Okay.
Gu Yanshu looked at Qin Jinzhe and said, "Jump out of the house. Look for danger. Come back."
Qin Jinzhe's face changed at once.
The ceiling shadow was still hanging above the crack. The room still had that hard, tight feeling from before. The control point still hummed softly. And now Gu Yanshu had said the one thing Qin Jinzhe was not willing to do.
Qin Jinzhe shook his head.
"No, I will not."
His voice was low, but firm.
He stood there with his shoulders tight, eyes locked on Gu Yanshu, as if he had already chosen to stay in place no matter what the room did next.
Gu Yanshu did not move.
He only looked at him for a second.
Then he said to the others, "Go to the Library of Learning. Investigate the book."
He Mulin, Qiu Weiran, Yu Chang, Lan Wege, and Qu Yaoyang all turned at once.
The command was simple. No one questioned it. They moved toward the corridor immediately, still tense, still carrying the pressure of what had happened in the room.
Qin Jinzhe stayed where he was.
His jaw was set.
He did not speak again.
He had already made his refusal clear.
Gu Yanshu watched the others leave, then turned back to Qin Jinzhe.
The second strongest disciple remained standing near the control point, his expression hard, as if he expected an argument to follow. But Gu Yanshu did not raise his voice. He did not argue.
He only stepped closer.
Qin Jinzhe's eyes shifted slightly, not from fear exactly, but from caution.
The room was still moving through the sky.
The house still hummed around them.
The shadow above the ceiling crack stayed in place.
And the door to the corridor was now shut behind the others.
Gu Yanshu looked at Qin Jinzhe and said, "You heard me."
Qin Jinzhe's lips tightened.
"Yes."
"Then go."
"No."
The answer came again, just as firm as before.
Gu Yanshu stared at him.
Not long.
Just enough.
Then his hand moved.
It was fast.
Too fast for Qin Jinzhe to step away, too fast for the room to change shape around it. The movement happened and ended in the same breath. One instant Qin Jinzhe was standing there with his head high, and the next he was no longer standing the same way.
The room seemed to go still.
The house kept moving, but inside the room there was a hard, sudden silence.
Qin Jinzhe's body dropped out of its stance and hit the floor.
The motion was abrupt, final, and so sudden that the air around the control point seemed to pull tight for a second.
Gu Yanshu did not look away.
He bent slightly, picked up what he needed from the moment, and then turned toward Xon Leon.
The senior brother stood there in his strange, unnatural calm, still quiet, still wrong, still carrying that same sense of something unfinished. Gu Yanshu moved to him without hesitation.
He lifted Qin Jinzhe's headless body with a short, controlled motion and placed the severed head into Xon Leon's hand.
The room did not react at first.
Then the shadow above the ceiling crack trembled.
The control point gave one faint click.
Xon Leon's hand settled around the weight.
Gu Yanshu adjusted the grip just enough to make it look deliberate.
Not messy.
Not uncertain.
Placed.
The hand held the head as if it had been meant to.
Then Gu Yanshu stepped back.
The room stayed silent.
The shadow above the ceiling crack shifted once more, as if it understood what had just been done and disliked it.
Qin Jinzhe was no longer standing.
Xon Leon's hand was now the clearest thing in the room.
And the scene had changed completely.
Gu Yanshu looked at Xon Leon's hand.
Then at the body.
Then at the door.
He did not say anything.
The house continued moving through Area 909.
The control point hummed.
The ceiling shadow stayed above the crack.
And the room held the new shape of the scene, waiting for the others to return.
It did not take long.
The five disciples came back from the Library of Learning in a cluster, their faces already serious before they opened the door. He Mulin entered first, followed by Qiu Weiran. Yu Chang came in with his head slightly lowered, Lan Wege at his side, and Qu Yaoyang bringing up the rear.
They stopped the moment they saw the room.
No one spoke for a breath.
Their eyes went immediately to Xon Leon.
Then to what was in his hand.
Then to the body of Qin Jinzhe on the floor.
He Mulin's face changed first.
The others followed after him.
Qu Yaoyang's eyes widened.
Yu Chang went still.
Lan Wege's mouth parted slightly.
Qiu Weiran looked from one body to the other, then back again, as if trying to force the room to make sense in the time it had left.
He Mulin took one step forward.
Then stopped.
His gaze fixed on Xon Leon's hand.
The hand.
The head.
The position.
Everything about it looked wrong enough to become convincing on its own.
He Mulin's voice came out low.
"Senior brother…"
He did not finish the sentence.
Qiu Weiran looked at Qin Jinzhe, then at Xon Leon, and then at Gu Yanshu.
His face tightened.
Yu Chang's brows drew in.
Lan Wege stared at the floor for a second, then lifted his eyes again, looking more confused than anything else.
Qu Yaoyang's gaze stayed on Xon Leon's hand.
The way it held the head was too obvious. Too placed. Too clean in its meaning.
He Mulin's jaw tightened.
"This means…"
He stopped again.
Because the room was already saying the rest for him.
Qu Yaoyang looked at Xon Leon and then said, almost under his breath, "He killed Qin Jinzhe."
Yu Chang looked shocked, but he did not interrupt.
Qiu Weiran's eyes sharpened.
Lan Wege's face hardened a little.
He Mulin took in one breath and looked like he wanted to say more, but no words came out.
The wrong shape of the room had done its work.
Xon Leon was standing there with Qin Jinzhe's head in his hand.
Qin Jinzhe's body was on the floor.
And Gu Yanshu stood off to the side, calm as ever, unreadable as ever, as if the whole thing had already been finished before anyone else walked back in.
He Mulin's voice lowered again.
"Xon Leon…"
The name came out carefully now.
Not respectful.
Not fully accusing either.
Just the name, spoken in the middle of a room that had already become too strange.
Qu Yaoyang took another look at the hand, then at the body, and his expression shifted again.
"It was him," he said.
Qiu Weiran didn't answer.
Yu Chang still looked uncertain, but even uncertainty had started to bend toward the scene in front of him.
Lan Wege said nothing, but his eyes had already settled into a darker line.
He Mulin stared hard at the hand.
The senior brother's hand.
The head in it.
The body at his feet.
Then he looked at Gu Yanshu, who had not moved.
He Mulin's voice came slower this time.
"Lord…"
Gu Yanshu finally spoke.
His voice was quiet.
"Look carefully."
He Mulin blinked once.
Gu Yanshu did not raise his voice.
"Look at what is in his hand. Look at what is on the floor. Look at what was refused."
The five disciples all went still again.
The sentence did not clear anything up.
It made the room feel even more wrong.
Because they had already seen what they had seen.
He Mulin looked back at Xon Leon's hand.
Qin Jinzhe's head rested there.
And because the room was already tense, because the ceiling shadow was still hanging above the crack, because Gu Yanshu had not denied anything in front of them, the simplest answer sat in their heads and would not leave.
Xon Leon did it.
He Mulin's face slowly hardened.
Qiu Weiran looked uneasy now, but he did not challenge the thought.
Yu Chang looked at Gu Yanshu, then at Xon Leon, then at Qin Jinzhe's body.
Lan Wege swallowed.
Qu Yaoyang looked like he had already decided.
It was not a clean decision.
It was not careful.
But the room had not given them a clean way to think.
So they took the easiest one.
He Mulin's voice was low.
"He refused your order."
Qin Jinzhe's body was already still.
Xon Leon's hand was still holding the head.
Gu Yanshu looked at He Mulin.
He said nothing.
He Mulin swallowed hard, then looked at the others.
"He refused the command, and then this happened."
The words made the others tighten.
Qiu Weiran's expression changed.
Yu Chang's eyes sharpened a little more.
Lan Wege looked down once and then away.
Qu Yaoyang did not say anything, but he did not disagree either.
The room had now become a story they could almost tell themselves.
A refusal.
A death.
A senior brother with the wrong thing in his hand.
That was enough for them to believe the shape of it.
Gu Yanshu watched them build it.
He did not correct them.
Not here.
Not now.
He let the wrong shape settle.
Then he said, very quietly, "What did you find in the Library of Learning?"
The five disciples turned toward him.
The question cut through the room.
He Mulin's face was still hard, but his eyes shifted.
Qiu Weiran looked more uncertain now.
Yu Chang's attention came back to the present.
Lan Wege lifted his head.
Qu Yaoyang's jaw tightened.
He Mulin answered first.
"The book spoke about the house's hidden layers."
Yu Chang followed, "And the control point."
Qiu Weiran added, "And the library shelf behind the ninth row."
Lan Wege said, "It spoke about the room reacting before the visible thing does."
Qu Yaoyang looked at Xon Leon's hand once more and then said, "It said some things answer through the wrong place."
Gu Yanshu heard them all.
Then he looked at the room.
The shadow above the ceiling crack had not moved again.
The control point still hummed.
The body on the floor still lay where it had fallen.
And the five disciples stood with the wrong conclusion beginning to root itself in place.
That was fine.
For now.
He Mulin looked at Xon Leon again and then asked, with a harder voice, "Was Qin Jinzhe killed because he disobeyed?"
No one answered immediately.
The room itself seemed to tighten at the question.
Qiu Weiran looked from He Mulin to Gu Yanshu.
Yu Chang's face held a flicker of confusion.
Lan Wege stayed silent.
Qu Yaoyang's eyes remained fixed on the hand.
Gu Yanshu finally answered.
"Continue reading."
He Mulin frowned.
"The book."
Gu Yanshu's voice stayed calm.
"Read the rest."
The disciples hesitated only briefly before turning back toward the corridor, though their eyes kept flicking to the scene behind them as they moved. He Mulin went first again. Qiu Weiran followed. Yu Chang came after him. Lan Wege and Qu Yaoyang trailed behind.
But they did not leave the room unchanged.
The wrong meaning had already been planted.
And Gu Yanshu knew that.
When the last of them had almost reached the door, He Mulin turned back once more and looked at Xon Leon's hand.
Then at Qin Jinzhe's body.
Then at Gu Yanshu.
His face had hardened into something heavier now.
Like he had already accepted what he thought he saw.
The door opened.
The five disciples went out again to the Library of Learning, this time carrying the image of Xon Leon holding Qin Jinzhe's head as if it were proof.
The room went quiet after they left.
Quiet enough to hear the hum of the house.
Quiet enough to hear the faint shift in the ceiling crack.
Quiet enough to feel that the scene had broken into two truths now.
One that was visible.
And one that had not yet been spoken.
Gu Yanshu stood in the room with Xon Leon still holding the wrong thing in his hand, the shadow above the ceiling crack still hanging back, and the door still open to the corridor.
Then, very softly, he said, "Good."
And the room stayed still.Gu Yanshu stood in the room for a moment after that.
The house was still moving.
The ceiling crack was still open.
The shadow above had not gone away, but it had also not come down any farther. It hung there in the upper layer of the room like a piece of night that had forgotten where to settle.
Then Gu Yanshu turned.
Not toward the ceiling.
Toward the window.
He walked to it slowly, put one hand near the frame, and looked outside.
The world below had changed again.
The land was moving past in long blurred bands, the sky pressed above the house, and the sense of motion had become different from before. It was not just fast now.
It was forward.
The numbers on the outer route marker flashed by the edge of the window frame, and Gu Yanshu's eyes stopped on them for one second.
Area 913.
He looked again.
It was not a mistake.
The house had crossed into Area 913.
The number sat there for a breath like a mark in the air, then slid behind them as the moving structure kept going.
Gu Yanshu held the window frame a little tighter.
Then he looked down once more.
The boundary line had already passed.
Area 913 was not coming.
It was here.
The room behind him stayed quiet.
That quiet had a strange shape to it now.
The ceiling shadow remained above the crack.
The control point still gave that faint hum.
Xon Leon still stood in place, holding the wrong thing in the wrong hand, while the room itself continued to move through the sky as if it had no intention of slowing down for anyone's questions.
Gu Yanshu stayed at the window for another second.
Then he closed it.
Very slowly.
The latch clicked softly into place.
The sound felt small in the room.
Too small.
Like it did not deserve to matter, and yet it did.
He turned away from the window.
The outer area marker had already disappeared behind them.
Area 913.
That was where they were now.
He looked around the room once.
No one spoke.
The shadow above the ceiling crack shifted by a fraction, as if it had sensed the boundary change too. The room felt narrower than before, but not because it had changed size. It felt narrower because the new area carried a different pressure.
The house did not move the same way in every region.
That much could be felt without needing words.
Gu Yanshu crossed back toward the center of the room.
Then he stopped.
The others had not returned yet.
The corridor was still empty.
The library door was shut.
The moving house kept sliding through Area 913, and the quiet inside the room now had a new edge to it.
Not only because of the shadow.
Because the house itself had entered a place that did not feel familiar.
Gu Yanshu looked once at Xon Leon, then at the control point, then at the ceiling crack.
He did not speak.
The room held itself.
Then, from somewhere in the corridor side of the house, there came a soft sound.
Not a footstep.
Not a knock.
Just a faint shift of pressure against the door, like something on the other side had moved a little too close.
Gu Yanshu's eyes moved in that direction.
The door remained shut.
He did not go to it.
He only watched.
The pressure did not repeat.
The room stayed still.
Then the ceiling shadow made one tiny movement.
The lower edge of it pulled inward, just slightly, like a thing that had heard something and did not want to admit it.
Gu Yanshu noticed.
He did not react.
The door remained shut.
The corridor remained quiet.
Area 913 kept sliding underneath the house, and the sense of boundary-crossing lingered in the air like a taste that would not go away quickly.
A little later, the library door opened.
The five disciples returned one after another, moving more slowly than before.
He Mulin came in first.
Qiu Weiran followed.
Yu Chang's expression was still serious.
Lan Wege looked unsettled.
Qu Yaoyang came in last, and the group stopped the moment they saw the room again.
The changed scene hit them at once.
Area 913 was now on the route marker outside.
The ceiling crack was still there.
The shadow above it was still hanging in place.
Xon Leon still stood in the room with the same wrong stillness around him.
The others' eyes moved from one thing to another.
Then back again.
He Mulin's face changed.
Yu Chang's brows pulled together.
Qiu Weiran looked at the room more carefully this time, as if trying to force the shape of it into something readable.
Lan Wege did not speak.
Qu Yaoyang stared at the window for a second, then at the floor, then at the ceiling crack.
Gu Yanshu looked at them all, then said, "You found something?"
He Mulin answered first.
"The book mentioned hidden layers."
Qiu Weiran added, "And the house's route memory."
Yu Chang said, "It spoke about places where the structure changes before the eye notices."
Lan Wege looked at the ceiling crack and then said quietly, "It said some sounds come before the room shows anything."
Qu Yaoyang was still looking toward the window when he spoke.
"It mentioned boundary crossings."
Gu Yanshu listened without changing his face.
The room was still quiet.
Area 913 sat outside the window now, and the moving house had a different pressure inside it than before.
He Mulin glanced toward Xon Leon again.
Then he looked at Gu Yanshu.
"There's something wrong with the room."
Gu Yanshu did not answer immediately.
He only stood there, looking back at him.
The shadow above the ceiling crack shifted once.
Not much.
But enough.
Qiu Weiran noticed it and turned his eyes upward for half a second before lowering them again.
Yu Chang saw it too.
Lan Wege's hand flexed once at his side.
Qu Yaoyang's face was hard to read now.
He Mulin's voice lowered a little.
"We saw the book," he said.
Gu Yanshu gave a slight nod.
Then he said, "Read it again."
The five disciples hesitated.
Not because they disagreed.
Because the room had changed while they were gone.
And now the same words felt different.
Qiu Weiran looked at the library door, then at Gu Yanshu.
He did not ask why.
He only moved first.
He Mulin followed.
Yu Chang went after him.
Lan Wege and Qu Yaoyang trailed behind.
Gu Yanshu did not stop them.
He stayed in the room.
The ceiling shadow remained above the crack.
Xon Leon stood where he had been left.
And the new area outside the window kept sliding by, as if the house had carried them into a place where every sound became a little more important than before.
A little later, the corridor side door opened again.
A breeze of moving-house air came through with the others returning from the library.
This time their faces were tighter.
He Mulin looked down as he entered.
Qiu Weiran's shoulders were stiff.
Yu Chang's expression had changed.
Lan Wege seemed uncertain.
Qu Yaoyang looked like he was trying not to look at the ceiling crack for too long.
Gu Yanshu watched them return.
They all stopped.
He Mulin said, "The book has another line."
Gu Yanshu looked at him.
He Mulin continued, "It says the house changes when it crosses deeper areas."
Qiu Weiran nodded once.
Yu Chang added, "It also says the ninth shelf shifts."
Lan Wege looked toward the back of the room and then said, "And the library can hear boundary changes."
Qu Yaoyang spoke last.
"It mentioned Area 913."
The room seemed to become stiller at that.
Gu Yanshu's eyes shifted once toward the window, then back.
Area 913 was not just the place outside anymore.
It was in the book too.
He Mulin saw the shift in Gu Yanshu's eyes and stepped half a pace forward.
"The book says the house's hidden channels become easier to hear after certain crossings."
Qiu Weiran looked at the ceiling crack again.
Yu Chang's voice was lower now.
"It also says if the upper layer opens, the lower layer will feel it."
Gu Yanshu stayed quiet.
Qu Yaoyang swallowed once, then said, "Something in the room is still listening."
No one answered him.
The room answered for them instead.
From above, very faintly, there came another soft scrape.
The five disciples all froze.
This time even Lan Wege looked up at once.
The ceiling shadow had not moved much, but the crack had widened by a sliver again.
The shape above still hung there.
Not leaving.
Not coming fully down.
Just waiting in that half-open way it had been all along.
He Mulin's voice dropped.
"Lord…"
Gu Yanshu looked at him.
He Mulin continued, "Should we stay here?"
That was a simple question.
But it made the room feel like it had become two places at once.
One place where the shadow above still hung.
One place where the library still waited.
Gu Yanshu did not answer immediately.
He walked toward the window again.
Area 913 still slid outside.
The house's movement had changed slightly since the earlier crossing. It was not slower. It was just less smooth.
The lines outside the window felt narrower.
The air felt more compressed.
Gu Yanshu watched the route marker fade and then turned back to the room.
"Stay close," he said.
The five disciples nodded at once.
He did not explain further.
He only looked once at the ceiling crack, then at the control point, then toward the corridor door.
Something had moved there before.
Not enough to show itself.
Enough to be heard.
He Mulin took a careful breath.
Qiu Weiran looked like he wanted to speak, but did not.
Yu Chang kept his eyes moving from the door to the ceiling and back.
Lan Wege stood a little closer to the others now.
Qu Yaoyang looked from Xon Leon to the door, then to the window, then back again.
The room stayed full of waiting.
Gu Yanshu turned and walked toward the corridor side.
He did not go all the way to the door.
He stopped a few steps short.
The others watched him.
The ceiling shadow remained above the crack.
The house kept crossing Area 913.
Then, from behind the door, came that same faint pressure again.
This time a little clearer.
A soft drag.
Then stillness.
He Mulin saw Gu Yanshu stop and looked at the others.
Qiu Weiran's face tightened.
Yu Chang's eyes narrowed.
Lan Wege held his breath.
Qu Yaoyang went still.
Gu Yanshu's voice was low.
"Someone is there."
No one argued.
The room did not need argument.
It was already enough.
He Mulin looked at the door.
"Should I open it?"
Gu Yanshu did not answer right away.
The shadow above the ceiling crack shifted again, a little lower this time, as if the sound outside had made it curious.
Then Gu Yanshu said, "Not yet."
He Mulin nodded.
The room stayed quiet again.
Area 913 slid beneath the house.
The route felt unfamiliar.
The pressure in the walls felt new.
The books in the library were now shut behind the five disciples, but the thought of the hidden shelf behind the ninth row seemed to stay in the air anyway, as if the answer had not been finished yet.
Qiu Weiran looked toward the library door, then back at Gu Yanshu.
"Lord… the book said the hidden chamber responds during boundary crossings."
Gu Yanshu heard him.
He did not turn.
"Then let it respond."
The sentence was quiet, but it changed the mood in the room.
Qu Yaoyang's eyes flicked toward him.
Yu Chang stood straighter.
Lan Wege looked toward the back of the room again.
The door remained shut.
The ceiling crack stayed open.
And then, very softly, the shelf near the back of the room made a dry sound.
Everyone heard it.
Even Xon Leon, standing still in the middle of the room, seemed to sharpen slightly at the sound.
He Mulin turned his head immediately.
Qiu Weiran followed.
Yu Chang's eyes widened a fraction.
Lan Wege looked almost startled.
Qu Yaoyang's mouth parted.
The shelf had not moved much.
Only enough to be noticed.
Gu Yanshu walked toward the back of the room.
The others held still and watched him go.
He stopped in front of the shelf and looked at it.
A thin seam had appeared where there had been none before.
Not large.
Just enough to suggest the shelf was not fully fixed anymore.
He touched the edge lightly.
The seam widened by a hair.
Then the shelf moved.
Not outward.
Sideways.
A hidden panel slid open.
The room remained very quiet.
The five disciples all leaned their attention toward it without moving their feet.
Inside the compartment was a narrow dark space and a book sitting alone in the center.
Gu Yanshu looked at it for a moment, then reached in and took it out.
The book was thinner than the others.
Its cover was dark gray.
No title.
He opened it.
The first page was blank.
The second page had one line written in a hand older than the others.
When the house enters Area 913, the hidden layer begins to remember.
He read the line again.
Then he turned the page.
The next page had a small map drawn in the center.
Not of the whole house.
Only of the room they were standing in.
There was a mark on the ceiling.
There was a mark by the door.
There was a mark at the back shelf.
And there was a mark near Xon Leon.
He looked at the page for a second longer, then turned to the next.
The page after that showed a corridor.
A narrow route.
And beside it, one line.
If the door answers first, do not answer at the same time.
Gu Yanshu's eyes stayed on the line.
The room behind him was very still now.
The shadow above the ceiling crack had not moved.
The door remained closed.
The five disciples were watching from a short distance away, waiting to see what the new book would say.
Gu Yanshu turned another page.
The next line read:
If the hidden chamber opens during the crossing, someone in the room will have to choose.
He stopped there.
The line seemed to sit in the air for a breath.
He Mulin looked at the book from where he stood.
Qiu Weiran's face tightened.
Yu Chang's gaze sharpened.
Lan Wege frowned.
Qu Yaoyang stayed quiet, but his eyes had moved from the door to the book and back again.
The house outside was still crossing Area 913.
The room felt tighter now.
Gu Yanshu kept the book open and looked at the next page.
A dark line appeared under his fingers as if the paper had just decided to write again.
He read it once.
Then again.
Then the line widened.
Not a lot.
Just enough.
The hidden chamber beneath the ninth shelf had answered.
And from behind the closed corridor door, the faint pressure returned one more time.The hidden chamber answered.
A thin sound came from behind the panel, almost like a small breath moving through a narrow gap. The book in Gu Yanshu's hand stayed open on the page with the dark line, and the line on the paper seemed to deepen by a shade, as if the page itself had been listening.
Behind him, the five disciples had gone quiet.
He Mulin was the first to notice that Gu Yanshu had stopped moving. Qiu Weiran noticed second. Yu Chang, Lan Wege, and Qu Yaoyang all held their positions without speaking, their eyes moving between the open panel, the book, the door, and the ceiling crack. The room had already changed once tonight. Now it was changing again.
Gu Yanshu did not look back at them.
He only turned the book one page.
The next page showed a line drawing of a door, a shelf, and a room within a room. Under the drawing was a sentence written in a thin hand.
When the hidden layer opens, do not touch it first.
He read that sentence once.
Then he closed the book halfway and looked toward the door.
The pressure there had not left. It had only waited.
The sound behind the corridor door came again. This time it was closer. A slow drag, like something had leaned its weight against the other side and was standing still to listen.
Qin Jinzhe was no longer on the floor. His body had already been moved out of the center of the room, and now the room itself seemed to have forgotten the exact shape of that earlier moment. The five disciples were all watching Gu Yanshu, waiting to see what he would do with the opened shelf, the book, and the sound behind the door.
Gu Yanshu looked at He Mulin.
"You hear it too?"
He Mulin nodded once. "Yes, Lord."
"Good."
That single word made He Mulin straighten a little.
Gu Yanshu looked at Qu Yaoyang next.
"You were the first one to say the wrong thing earlier."
Qu Yaoyang's face changed.
He did not speak.
Gu Yanshu continued, "You saw a hand and a body and thought the hand was enough."
Qu Yaoyang lowered his eyes.
Gu Yanshu shifted to Yu Chang.
"You look at the center first. That is why you miss what comes in from the side."
Yu Chang's brows tightened slightly, but he did not interrupt.
Gu Yanshu then looked at Lan Wege.
"You keep watching the ceiling because you think danger only matters when it is large."
Lan Wege said nothing.
Gu Yanshu's gaze moved to Qiu Weiran.
"And you, when the room changes, you wait for someone else to tell you what it means."
Qiu Weiran stayed still.
Then Gu Yanshu looked at all five of them together.
"You are all here because the book was not enough."
No one answered.
The room stayed silent except for the hum of the moving house and that soft pressure behind the corridor door.
Gu Yanshu set the gray book down on the open shelf panel and shut it lightly, just enough to leave it where it could be seen.
Then he walked to the center of the room.
He did not go to the door.
He did not go to the ceiling crack.
He did not go to the shelf.
He stood in the middle and looked at each disciple one more time.
"Qin Jinzhe heard the sound outside," he said. "He did not speak. That was a mistake."
The five disciples looked toward Qin Jinzhe at once, then back to Gu Yanshu.
"He should have spoken sooner," Gu Yanshu continued. "The room would have changed sooner."
The sentence made the others go quiet in a different way.
It was not praise.
It was not punishment.
It was a way of placing blame in a shape they could understand.
Gu Yanshu turned back toward the shelf.
The hidden panel was still open.
The book inside it sat in the dark like it had already decided to stay there.
He did not touch it again.
Instead he walked to the door.
The pressure outside had not changed. The same faint drag came once more from behind the wood.
Gu Yanshu stood close enough to the door to feel the air shift around it.
Then he spoke, not loudly, but clearly.
"You've been listening for too long."
The room tightened.
He Mulin's eyes sharpened.
Qiu Weiran looked from the door to Gu Yanshu's face.
Yu Chang's breath slowed.
Lan Wege moved half a step closer to the others.
Qu Yaoyang watched the doorknob.
From the other side, the sound stopped.
Gu Yanshu's voice stayed calm.
"You want the house to answer first."
He said it like a fact.
Not a guess.
Not a theory.
The five disciples looked at him.
The corridor remained quiet.
Then Gu Yanshu turned his head a little and looked back at the open shelf.
"Qiu Weiran."
Qiu Weiran straightened.
"Take the book back."
He moved immediately.
Gu Yanshu continued, "He Mulin, stand by the panel."
He Mulin obeyed.
"Yu Chang, watch the corridor door."
Yu Chang moved to the side.
"Lan Wege, watch the ceiling crack."
Lan Wege lifted his head.
"Qu Yaoyang, watch Xon Leon."
Qu Yaoyang's gaze snapped toward the senior brother at once.
That left Gu Yanshu standing in the middle again.
The room now had a shape.
Book.
Panel.
Door.
Ceiling.
Xon Leon.
And the people placed around them.
Gu Yanshu let the silence settle for one breath.
Then he said, "If something moves, do not rush it. You will only show it where to go."
The others nodded almost at the same time.
No one spoke.
The house kept moving through Area 913.
The control point hummed.
And then the book under Qiu Weiran's hands made a very soft sound.
Like a page shifting by itself.
Qiu Weiran froze.
He looked down.
The book had opened one page farther on its own.
He did not touch it.
Gu Yanshu noticed.
"Read it."
Qiu Weiran's eyes scanned the page.
His face changed slightly.
He looked up again, not understanding everything, but enough to know the page had changed at the right time.
"It says…" he began.
Gu Yanshu waited.
Qiu Weiran swallowed.
"It says the hidden chamber opens when the room is being watched by too many directions."
That made the others still.
Gu Yanshu nodded once.
Very small.
Very controlled.
Then he turned toward the shelf again and looked at the open panel.
The hidden chamber had already answered once.
Now it was waiting for the room to become crowded in the right way.
That was the kind of thing that could be used.
He looked at He Mulin.
"Bring the book here."
He Mulin did.
Gu Yanshu took it, opened it again, and turned one page at a time until he found the line he wanted. He did not look hurried. He let every movement be visible. Let the room see that he was not afraid of the panel, the door, or the crack above.
Then he spoke to all five disciples.
"You will stand where I put you."
No one objected.
He pointed once.
He Mulin shifted left.
Qiu Weiran moved to the other side.
Yu Chang took a step toward the door.
Lan Wege moved closer to the ceiling crack.
Qu Yaoyang stepped back and angled himself toward Xon Leon.
Gu Yanshu watched the arrangement.
Then he turned and moved to the corridor door.
The pressure outside had changed again.
Still there.
Still waiting.
Gu Yanshu raised his hand and tapped the wood twice.
The sound was light.
Inside the room, every disciple held still.
The shape behind the door moved.
Not much.
Enough.
Gu Yanshu turned back to the others.
"The thing outside wants a response," he said. "It wants us to open the wrong side first."
No one asked how he knew.
They were past that now.
Qiu Weiran held the book tightly.
He Mulin kept his position by the panel.
Yu Chang stayed on the door.
Lan Wege watched the crack.
Qu Yaoyang watched Xon Leon.
The room was now split into six attention points.
Gu Yanshu stood in the center and looked at the whole thing once.
The hidden chamber under the shelf.
The door.
The ceiling crack.
Xon Leon.
The moving house.
The five disciples.
Then he spoke to Qiu Weiran.
"Read the next line."
Qiu Weiran lowered his eyes to the book and read it out.
"When the room is divided correctly, the hidden layer opens from the side that was ignored first."
The sentence sat in the air.
He Mulin looked toward the panel.
Yu Chang looked toward the door.
Lan Wege kept watching the crack.
Qu Yaoyang glanced toward the shelf and then back to Xon Leon.
Gu Yanshu turned his head toward the panel.
There was a soft sound from inside it.
A single click.
The hidden chamber had shifted again.
Qiu Weiran's grip tightened on the book.
"It's opening," he said quietly.
Gu Yanshu nodded.
Then he looked at the door and said, "Do not answer it."
Yu Chang kept his hand near the frame without touching it.
The sound outside the door came again.
This time shorter.
Then silence.
Gu Yanshu spoke again.
"Qu Yaoyang, what is Xon Leon doing?"
Qu Yaoyang looked.
His voice was low.
"Nothing."
Gu Yanshu stared at him for one second.
Then asked, "Nothing at all?"
Qu Yaoyang looked closer.
The room had been moving this whole time, but Xon Leon still carried himself in that same strange quiet. Then Qu Yaoyang noticed something in the hand.
The grip had shifted.
Not much.
Enough.
He said, "His hand moved."
Gu Yanshu turned his eyes there.
Xon Leon's hand was now a little more open than before. Not fully. Just enough to show that the thing placed there was no longer resting exactly the same way.
The senior brother had not spoken.
Had not moved the rest of his body.
But his hand had changed.
That was enough for Gu Yanshu.
He looked at the others.
"Stay exactly where you are."
The room did.
He moved toward Xon Leon without hurrying.
The shadow above the crack shifted too.
Gu Yanshu noticed that the moment he stepped toward the senior brother, the line behind the door stopped making sound entirely.
That meant the room was listening to the movement.
Good.
He wanted it listening.
The closer he got to Xon Leon, the more the open panel behind him seemed to deepen. The hidden chamber under the shelf had not fully opened, but it had widened enough to show a darker space inside.
Qiu Weiran saw it and whispered, "Lord…."
Gu Yanshu did not turn.
He reached Xon Leon and took the object from his hand.
The room changed immediately.
Not violently.
Not softly either.
It just shifted.
The air in the room felt suddenly more direct, like something had been removed from the middle of a sentence.
The shadow above the crack tightened.
The door remained quiet.
Qin Jinzhe, still near the edge of the room, looked between Gu Yanshu and the others with a face that said he knew this was not over.
Gu Yanshu held the object in one hand and looked at the others.
The five disciples were staring now.
He Mulin looked like he wanted to ask what had just changed.
Qiu Weiran's attention was fixed on the open panel.
Yu Chang was still watching the door.
Lan Wege kept glancing between the ceiling and the shelf.
Qu Yaoyang's eyes were on Xon Leon's hand.
Gu Yanshu did not speak yet.
He only turned the object once in his fingers and then looked at the hidden chamber.
The chamber had opened wider.
Inside it, another book could be seen.
Smaller.
Thinner.
Deeper in the dark.
He Mulin noticed and took one step forward.
Gu Yanshu stopped him with one glance.
He Mulin froze.
Gu Yanshu then looked at Qiu Weiran.
"Read the last line."
Qiu Weiran lowered the book again and read.
"When the hidden layer opens, the wrong witness leaves with the wrong truth."
The room stayed still.
No one spoke.
Then the corridor door made that same faint sound again.
Very soft.
Very close.
This time the sound was followed by a little pressure on the wood.
Not a knock.
A presence.
Yu Chang's hand stiffened on the frame.
Gu Yanshu turned toward the door.
Now he knew what the room wanted them to do.
It wanted a choice.
The hidden chamber had opened.
The wrong truth had already begun to form.
And the thing outside the door had not stopped listening.
He looked at the five disciples.
Then at Qin Jinzhe.
Then at Xon Leon.
Then at the open panel.
And finally at the corridor door.
"Stay ready," he said.
No one moved.
The house kept going through Area 913.
And the door waited.Gu Yanshu closed the smaller book slowly.
Then he looked at the others and said, "Keep your positions."
No one moved.
The room stayed tight.
The house kept crossing through Area 913, and the air inside the library felt thinner than before, as if the open hidden panel, the ceiling crack, and the closed corridor door were all pulling at the same thread.
He Mulin stood by the panel with one hand still near the shelf edge.
Qiu Weiran held the other book open but did not turn the page.
Yu Chang kept his body angled toward the corridor door.
Lan Wege watched the ceiling crack without blinking.
Qu Yaoyang stayed fixed on Xon Leon's hand and the stillness around him.
Gu Yanshu stepped once toward the center of the room, then stopped.
The small book in his hand did not move.
Neither did the hidden chamber.
Then, from behind the corridor door, came another soft sound.
Not a knock.
Not a step.
A slow pressure, as if something on the other side had leaned closer and was listening through the wood.
Yu Chang's fingers tightened against the doorframe.
He did not open it.
Gu Yanshu looked at him once.
"Do not answer it."
Yu Chang nodded.
The shadow above the ceiling crack shifted by a fraction.
The thin line hanging down from it drew in slightly, then steadied again.
Lan Wege noticed and lifted his chin a little higher.
"It moved."
Gu Yanshu heard him.
"Yes."
That was all.
The room did not need more.
The hidden chamber under the shelf remained open, and the small book inside Gu Yanshu's hand carried a page with a blank center and a single word beneath it.
Choice.
He looked at the word one more time, then closed the book halfway.
Not all the way.
Enough to hold it steady in his hand.
The house moved on.
A faint hum rolled through the floor.
It changed the feeling of the room by a small amount, but it was enough for everyone to feel it. The library shelves did not shake. The floor did not lurch. The air simply adjusted, and the pressure of Area 913 settled a little more deeply around the room.
Qu Yaoyang was the first to notice that the book he held had changed again.
He lowered his eyes and read.
His expression shifted.
"The page is different."
Gu Yanshu turned his head.
"Read it."
Qu Yaoyang swallowed once, then read the line aloud.
"When the house crosses the deeper route, the hidden layer stops waiting and begins answering."
The sentence hung in the room for a second.
He Mulin's face hardened.
Qiu Weiran looked down at the book in his own hands.
Yu Chang's eyes shifted from the door to the shelf and back again.
Lan Wege kept watching the ceiling crack.
Gu Yanshu did not speak for a moment.
Then he stepped toward the open hidden panel and placed the smaller book beside it.
The hidden chamber remained open.
Inside, the dark space looked a little deeper than before.
He Mulin glanced toward it.
"Lord…"
Gu Yanshu looked at him.
He Mulin hesitated, then spoke carefully.
"The chamber is not empty."
Gu Yanshu nodded once.
"No."
That answer made He Mulin go still.
Gu Yanshu continued, "It only looks empty because the thing inside is not fully showing itself yet."
He Mulin's eyes moved to the dark inside the shelf.
The others heard the words too.
The room tightened.
Qiu Weiran kept the other book open and turned another page.
His voice came out lower now.
"There's another line."
Gu Yanshu looked at him.
Qiu Weiran read it aloud.
"When the wrong witness is removed, the room becomes clearer."
The line was short.
Too short.
The others all looked at the book.
Yu Chang's brows drew together.
Lan Wege's eyes shifted.
Qu Yaoyang stayed quiet.
He Mulin looked toward the door again.
The pressure behind it had not left.
It was still there.
Waiting.
Then Gu Yanshu moved.
Not to the door.
To Xon Leon.
He crossed the room slowly and stood in front of the senior brother. The body remained in that same strange state, quiet and wrong, as if it had settled into a pause that did not belong to ordinary people.
Gu Yanshu looked at Xon Leon's hand.
The hand still held the wrong thing.
Not clean.
Not natural.
But placed.
The room had already made its judgment once. That was why the others had gone away carrying the wrong shape of the scene with them. Now only the room, the shelf, and the door were left with the remaining pressure.
Gu Yanshu lifted the smaller book again.
The page with the word choice remained open.
Then he looked at the others.
"Watch carefully."
No one moved.
He held the book above Xon Leon's hand for a second, then lowered it slightly until the shadow from the pages fell over the hand.
The room changed.
Not loudly.
The change came through the floor first. A small shift in the hum. Then a faint movement from the ceiling crack. Then the hidden chamber under the shelf gave one dry sound.
He Mulin turned his head sharply.
The chamber was answering.
The small book inside it had shifted by itself.
Gu Yanshu watched it and then looked back at the others.
"Do not touch the door."
Yu Chang nodded once.
"Do not touch the ceiling crack."
Lan Wege stayed still.
"Do not close the panel."
He Mulin held position.
"Do not turn the page too fast."
Qiu Weiran froze with the book open.
The room had become a set of balances.
The hidden chamber.
The ceiling crack.
The door.
The book.
Xon Leon.
And Gu Yanshu moving between them.
He turned one page in the smaller book.
The next line appeared almost immediately, as if it had been waiting for him to reach it.
The false center leaves the room first.
Gu Yanshu read it twice.
Then he lifted his head.
The others were all watching him now, waiting for the next thing to happen.
He did not speak at once.
Instead he turned toward the corridor door.
The soft pressure behind it had become still again.
Too still.
The kind of stillness that means the thing on the other side is no longer leaning in to listen.
It is waiting to hear whether the room will open itself.
Gu Yanshu stepped toward the door.
Yu Chang shifted automatically, but Gu Yanshu's hand stopped him with a small motion.
"Stay."
Yu Chang stopped.
The door stayed shut.
Then Gu Yanshu took the smaller book and pressed it lightly against the wood.
The room held its breath.
The door did not open.
But the pressure behind it changed.
A soft sound passed through the wood.
Then silence.
Qu Yaoyang's eyes narrowed.
He looked at the door, then at Gu Yanshu.
"It reacted."
Gu Yanshu gave one short nod.
The hidden chamber under the shelf made a small click.
He Mulin turned at once.
The panel had shifted again.
Not outward.
Only inward.
Like something inside it had adjusted its position.
Qiu Weiran saw it too and held his book more tightly.
The page he was reading had changed again.
He looked down and read.
"There is one place the room keeps its true answer."
Gu Yanshu looked at the page in Qiu Weiran's hands.
Then at the hidden chamber.
Then at the ceiling crack.
Then at the door.
He knew enough now to feel the shape of the trap, even if he did not need to name it yet.
The room had split attention before.
Now it was trying to force attention into one place.
That meant the true answer was not where everyone was looking.
It was where no one wanted to look yet.
He turned toward Lan Wege.
"Watch the ceiling."
Lan Wege nodded.
He turned toward He Mulin.
"Watch the panel."
He Mulin obeyed.
Then he looked at Qiu Weiran.
"Read the next line."
Qiu Weiran turned the page carefully.
His face changed a little when he read it.
He looked up.
"The hidden chamber opens fully only when the room accepts that the first door was never the only door."
The line stayed in the air.
Qu Yaoyang frowned.
Yu Chang looked from the corridor door to the shelf and then back again.
The room had become strange in a new way.
Not because anything had moved.
Because everything had started to look connected.
Gu Yanshu turned toward the open chamber and reached inside.
The small book in the hidden panel had already shifted farther forward than before.
He took it out.
The moment it left the chamber, the ceiling crack gave a tiny scrape.
Lan Wege looked up instantly.
The shadow above the crack had moved again.
Not far.
Enough.
Gu Yanshu did not look up.
He opened the small book.
The first page showed a drawing of the room with the shelf, the ceiling crack, the door, and the center marked empty again.
The second page had only one sentence.
The room accepts one answer at a time.
He read that once.
Then again.
Then he turned the page.
The next page had a second sentence.
If too many answers enter at once, the true one hides.
Gu Yanshu paused there.
That explained the shape of the room now.
Not in full.
Just enough.
He looked at the five disciples.
They were all watching him with different expressions, but none of them looked calm anymore.
He Mulin was serious.
Qiu Weiran was focused.
Yu Chang was alert.
Lan Wege looked upward often.
Qu Yaoyang kept glancing at Xon Leon.
Gu Yanshu spoke quietly.
"Leave the books open."
Qiu Weiran and He Mulin both adjusted their grip.
He continued, "Keep the door in sight."
Yu Chang turned his body slightly.
"Keep the ceiling in sight."
Lan Wege lifted his eyes.
"Keep the panel open."
He Mulin did.
"Keep Xon Leon in sight."
Qu Yaoyang stayed fixed on him.
The room now had five points of attention around it.
That was what Gu Yanshu wanted.
Not a rush.
Not a clash.
A room held in place by too many eyes for one hidden thing to move freely.
The door behind Yu Chang made a faint sound.
Again.
This time, Qu Yaoyang heard it too.
He turned.
The pressure behind the wood had not gone away.
It was simply holding still now.
Gu Yanshu looked at the smaller book again.
The page in front of him changed while he watched it.
A line appeared slowly.
When the room is held correctly, the hidden layer will answer.
He read it.
Then he moved one step toward the center of the room.
The others kept their positions.
The ceiling crack remained open.
The hidden chamber remained open.
The corridor door remained shut.
The house outside remained in Area 913.
Gu Yanshu stopped at the center and looked at all of them once.
Then he said, "Now we wait."
No one spoke.
The silence in the room was different again.
Not empty.
Held.
The hidden chamber under the shelf gave one soft click.
The door behind Yu Chang made one shallow sound.
The ceiling crack widened by one fraction.
And the small book in Gu Yanshu's hand turned its next page on its own.The room stayed still after the soft breath came from the doorway.
Not silent.
Still.
The difference mattered.
Silence was empty. Stillness was full.
The corridor opening remained narrow, just a hand's width, and nothing stepped through yet. The shelf panel stayed half-open behind them. The ceiling crack held its line above. The black strip on the floor sat in the center of the room like a stain that had learned how to wait.
Gu Yanshu did not move.
Neither did the others.
He Mulin stood near the shelf, his hand still close to the panel but not touching it. Qiu Weiran kept the book open in both hands, his eyes flicking between the page and the doorway. Yu Chang was frozen by the door, one hand near the frame, his body turned toward the opening without leaning into it. Lan Wege kept his head lifted toward the crack above, and Qu Yaoyang had turned slightly so he could watch both Xon Leon and the corridor at the same time.
The house kept moving through Area 913.
Outside the windows, the land below slid past in long blurred lines. The light beyond the glass looked thinner here, like the route had taken them somewhere with less color in it. The moving house did not shake. It only carried the feeling of crossing deeper into itself.
The soft breath came again from the corridor side.
A little clearer this time.
Yu Chang's fingers tightened on the doorframe.
Still nobody stepped forward.
Gu Yanshu looked at the narrow gap, then at the black strip in the center of the room.
The strip had not moved since it reached the middle. It lay there flat and long, dark as wet ink, but it did not shine. It seemed to absorb the little light that reached it.
Qiu Weiran swallowed and looked down at the book.
Another line had formed.
His voice came out very quiet.
"Lord… the page changed again."
Gu Yanshu did not turn yet.
"Read it."
Qiu Weiran lowered his eyes.
The line was short.
The witness has entered.
The room changed at once.
Not visibly at first.
The pressure shifted.
The ceiling crack seemed to lengthen by a hair, and the shadow above it drew in slightly, as if it had heard the page and adjusted its own shape.
The corridor opening stayed narrow.
Then, from inside the doorway, a second sound came.
A step.
Soft.
Careful.
It did not enter the room.
It only moved just behind the opening.
Yu Chang's breath caught.
He looked to Gu Yanshu once.
Gu Yanshu still did not move.
"Stay," he said.
Yu Chang stayed.
The black strip in the center of the room gave one very small twitch.
He Mulin saw it and stiffened.
Qiu Weiran noticed too and lowered the book a little.
Lan Wege's eyes sharpened.
Qu Yaoyang's mouth pressed flat.
The strip moved again.
This time it did not slide toward the door or the shelf. It rose a fraction from the floor, then settled again, like something inside it had just realized it was being watched from three directions at once.
Gu Yanshu finally took one step toward the center.
The room held.
He took another.
The black strip did not retreat.
It only turned its narrow edge a little, as if it had no face but still knew where the room's attention was landing.
The shadow above the crack shifted very slightly.
Not enough for anyone to call it a movement.
Enough for everyone to notice.
Gu Yanshu stopped near the strip and looked down at it.
It looked thinner this close.
Not longer.
Thinner.
Like a line that had been drawn twice and then pressed flat.
He crouched slightly.
The strip did not move away.
Then, from the corridor opening, the soft breath came a third time.
This time the sound carried a small wet scrape at the end of it, like something had brushed the wood on the other side.
Yu Chang's eyes widened a fraction.
He did not open the door.
He did not speak.
But his shoulders tightened hard enough that the others could see it.
Gu Yanshu remained crouched by the strip.
Then he put one hand near it, not touching, just close enough to feel whether it changed.
It did.
The strip drew in one millimeter.
Then stopped.
He did not pull his hand back.
The room had become so held in place that even this small movement felt large.
The black strip remained where it was.
Then, from the shelf panel, the hidden chamber answered again.
A small click.
He Mulin jerked his head toward it at once.
The panel had opened a little wider while nobody was looking directly at it.
Not much.
Enough to show the edge of the small book inside had shifted forward again.
Qiu Weiran's eyes widened.
"That book is moving."
Gu Yanshu stood up slowly and looked at the hidden chamber.
The smaller book inside it had not fallen out.
It had only slid forward by another inch.
The page edges were visible now, pale against the dark inside of the compartment.
The room had become very quiet again.
The corridor opening held its stillness.
The ceiling crack held its shape.
The shelf panel remained open.
The black strip at the center sat in place like a marker.
And the house continued to carry them through the deeper route.
Gu Yanshu looked at the five disciples.
Then he looked at the opening in the corridor.
Then back at the shelf.
The room felt as if it had split into three separate listens.
One for the door.
One for the ceiling.
One for the shelf.
He moved toward the shelf panel.
He Mulin stepped aside immediately.
Gu Yanshu reached in and took the small book out.
The moment it left the hidden chamber, the room gave a very faint hum.
The black strip in the center of the floor twitched once.
The opening in the corridor held still.
The shadow above the crack lowered by a line.
Gu Yanshu opened the book.
The first page had one sentence already waiting.
The witness is not the door.
He turned the page.
The next line appeared slowly.
The witness is not the shelf.
He turned again.
The third line came up even slower.
The witness is what remains when the room has finished choosing.
Gu Yanshu's gaze stayed on that line for a second.
Then he looked at the black strip on the floor.
It was still there.
Still flat.
Still waiting.
He heard movement behind the corridor opening again.
Not a full step.
A slight shift.
As if something had moved a shoulder or leaned a little closer without entering.
Yu Chang's breathing changed.
Gu Yanshu looked at him.
"Do not answer it."
Yu Chang nodded once.
The book in Gu Yanshu's hand turned a page by itself.
No one touched it.
The page came up clean, and a new line appeared at the top.
When the witness arrives, the room forgets one of its names.
That line sat there for a moment before the rest of the page filled in below it.
He read on.
The name forgotten first is usually the one nearest the door.
He lifted his eyes to the corridor opening.
The room had already begun to feel that way.
Not empty.
Just less fixed.
He Mulin's face changed a little.
Qiu Weiran looked from the book to the panel.
Lan Wege stayed under the crack, but his expression had tightened.
Qu Yaoyang's attention stayed between Xon Leon and the corridor.
The black strip on the floor moved.
Only a little.
It drew itself longer across the center, then stopped again.
Gu Yanshu looked at it closely.
It was no longer a strip.
Not fully.
It had become a line that seemed to hold the space between floorboards together.
Then the corridor opening gave a tiny shift.
Something had moved behind it again.
This time the sound was accompanied by the faintest scrape of fabric or wood, impossible to tell which. It was close enough for Yu Chang to feel it, because his hand tightened immediately on the frame.
The others noticed that too.
No one spoke.
The room had become a place where every small response stood out.
Gu Yanshu turned one more page in the book.
The page showed a rough drawing of the room again.
The door was open a little wider now.
The shelf panel had shifted farther.
The ceiling crack had lengthened.
The black strip on the floor was drawn as a dark line through the center.
And at the end of the corridor opening there was a small empty figure, drawn as if it had been left out on purpose.
Below the sketch was one short line.
Do not greet the witness first.
Gu Yanshu looked at the line.
Then he closed the book halfway and held it at his side.
He did not move toward the corridor opening.
He did not move toward the ceiling crack.
He did not move toward the shelf.
He only stood in the center of the room, with the black strip at his feet and the others spread around him.
The house moved again through Area 913.
This time the motion was smoother.
The room felt almost calmer.
That made the pressure behind the door harder to ignore.
Yu Chang looked at Gu Yanshu once, as if waiting for the next instruction.
Gu Yanshu did not give one yet.
He only said, "Keep your eyes where I placed them."
The disciples held position.
The shadow above the ceiling crack lowered a fraction.
The room did not react immediately.
Then the black strip on the floor lifted at one edge.
Not high.
Just enough.
The line started to turn toward the panel.
He Mulin saw it first and took a small breath.
The line shifted again.
Now it was moving in the direction of the hidden chamber.
Qiu Weiran's eyes widened.
"It's going back."
The strip did not answer him.
It slid across the floor, slow and smooth, toward the open shelf panel.
Gu Yanshu stepped in front of it before it could reach the edge.
The line paused.
The shelf panel gave a quiet click at the same time.
The small book inside the hidden chamber moved another inch forward.
Lan Wege's gaze snapped to the ceiling crack again.
The shadow above it was now lower than before.
It looked like the upper layer of the room had begun to pull toward the center.
The corridor opening stayed open.
The pressure behind it had gone very still.
Then the book in Gu Yanshu's hand turned its page by itself once more.
This one had only three words.
Choose the witness.
The words sat there for a moment.
Qiu Weiran saw them from the side and his expression changed.
He Mulin noticed too.
Yu Chang's eyes flicked to the corridor door.
Lan Wege looked at the ceiling crack.
Qu Yaoyang stared at Xon Leon.
The room had now put all of them in a strange kind of waiting.
The black strip at the center remained where it was.
Gu Yanshu looked down at it.
Then he looked up at the ceiling crack.
Then toward the corridor opening.
Then back to the hidden panel.
The room had not yet made the choice for them.
The small book remained in his hand.
He opened it again.
The next page was almost blank.
Only one line was written at the bottom.
The chosen witness will make the next sound.
Gu Yanshu's eyes stayed on the page.
Then, from behind the corridor opening, the same soft breath came again.
This time it was deeper.
Longer.
And after it came a second sound.
Not a step.
Not a knock.
A slow dragging shift, as if something had moved its weight from one side of the doorway to the other.
Yu Chang's face went still.
He did not open the door.
The black strip in the center of the room trembled once, then stopped.
The shadow above the ceiling crack pulled down another line.
The shelf panel clicked.
The small book inside the chamber moved a final inch forward, until half of its cover could be seen.
He Mulin stared at it.
Qiu Weiran held his breath.
Lan Wege lifted his chin.
Qu Yaoyang stayed fixed on Xon Leon.
Gu Yanshu closed the book in his hand and looked at the room one more time.
The house kept moving.
Area 913 slid below them.
The corridor opening remained narrow.
The ceiling crack held.
The shelf panel stayed open.
The black strip at the center did not move.
Then, from the corridor opening, a shape appeared.
Only a little.
Just the edge of it.
A shoulder line, maybe.
Or the side of a body.
It was hard to tell because it stayed half-hidden behind the door.
The room did not make a sound.
Even the house seemed to quiet down around it.
Gu Yanshu did not step forward.
He only looked at the shape at the doorway.
It did not enter.
It stayed in the opening.
And the moment it did, the small book in Gu Yanshu's hand turned to a fresh page on its own.
