"This is the last one."
"It should be on the wall, search carefully."
"Boing~"
A soft Slime body slammed into his hand.
With astonishing elasticity, it was immediately bounced back.
Lumine, beside him, quickly followed the rhythm.
Her longsword danced lightly, directly slicing the Hydro Slime into a puddle of sticky liquid on the spot.
In Stormterrors Lair, there were monsters and Slimes.
Although, theoretically speaking… for places with overly concentrated elemental energy, Hilichurl, who are more inclined towards Abyssal energy, would instinctively resist and not approach.
But just like the principle of survival of the fittest, over countless years, the Hilichurl remaining here gradually adapted to the environment of Stormterrors Lair and thus survived.
This did cause some trouble for Kai when collecting the parts.
However, fortunately, Lumine had forcefully dealt with them all with her sword.
Watching Paimon, full of fighting spirit, fly to the dilapidated wall and search meticulously, Kai stretched lazily.
He sighed slightly, "This finally brings an end to the boring collection journey."
Collecting parts was truly quite boring.
In fact, Kai himself didn't particularly like it.
However, having Paimon help wasn't because he wanted to be lazy.
It was purely because the parts were scattered in various strange corners.
In such a situation, with Paimon's small stature, she was indeed very suitable for collecting parts.
"I wonder how things are going with Diluc and Venti."
After confirming there was no danger around, Lumine exhaled softly, clearly having expended a certain amount of stamina.
"Them?"
"Let me see."
Hearing the question, Kai thought for a moment.
He turned to look at the distant tall tower.
Almost simultaneously… the three layers of glowing rings surrounding the outer perimeter of the tall tower crumbled one by one at a visible speed; a slight tremor could be vaguely felt even from a great distance.
After a moment, a red figure, utilizing the nearby wind currents, flew directly into the tall tower.
"Hmm, Diluc seems to have completed his task."
"As for Venti, he's probably almost done too."
"So, we'll be able to confront Dvalin directly in a little while, won't we?"
Withdrawing his gaze, Kai turned around and casually explained to Lumine.
"This…"
Lumine clearly hadn't expected him to be able to see the situation at the tall tower from such a distance.
Facing the vast expanse of the green storm barrier, Lumine's delicate little face froze, her clear eyes filled with surprise.
"Mr. Kai, you can see from so far away?"
"Just call me Kai, no need to be so polite."
Waving his hand, Kai never particularly liked people using honorifics with him, especially close acquaintances.
"My eyesight has always been quite good. It was enhanced during my travels in other worlds. If the weather is clear, even standing on the mountain top behind Qingce Village, I can see all the way to Stormterrors Lair."
"What is Qingce Village?"
Blinking, Lumine had clearly never heard of the place Kai mentioned.
"It's a very pleasant village in the Liyue region, with a great environment."
"From there, you can see Stormterrors Lair in the distance."
Kai explained simply, though it didn't draw too much attention from Lumine.
After all, as residents of the continent of Teyvat, it wasn't strange to have left Mondstadt to travel to other nations.
Especially since Liyue was a neighboring country.
However, "Just by looking into the distance, I can see the scenery far away?"
Lumine murmured to herself, suddenly thinking of something.
Her mood suddenly became heavy.
"If I stand far away and gaze…"
"I wonder… if I can see my brother."
"Your brother, huh?"
Kai withdrew his scattered gaze.
With his arms crossed, he faced the heavy-hearted girl.
He couldn't help but show a slightly gentle smile.
"Perhaps at this moment, he's thinking the same thing?"
"Hmm?"
Lumine looked up, meeting Kai's clear and bright eyes, seeing that seemingly heartfelt smile.
