Ms. Yoon had created the appointment system by Tuesday evening.
It had three fields.
Name. Sect affiliation. Technique name.
It had a notes column.
The notes column was already very long.
Park Sung-Jin had printed the appointment list for Wednesday afternoon and brought it to Han-Ho at the GS25 on Tuesday morning because Han-Ho was on the route and Park Sung-Jin had learned that delivering information to Han-Ho on the route was more efficient than waiting for Han-Ho to come to the Registry.
Han-Ho looked at the list.
"Eleven appointments," said Han-Ho.
"The Sword Saint arranged them," said Park Sung-Jin. "He sent messages through the Dragon Vein Gate yesterday. The appointments filled within four hours."
"Eleven techniques in two hours," said Han-Ho.
"Two hours was your availability window," said Park Sung-Jin. "Before four PM."
Han-Ho looked at the list.
1. Wei Liang — River That Cuts Heaven (follow-up assessment)2. Cheon Daehyun — Mountain Heart Sutra3. Pak Junseok — Iron Body Foundation4. Lee Hana — Ten Thousand Petals5. Choi Gwangsoo — Thunder Step6. Ma Jinyeol — Void Sword7. Kim Sooah — Flowing Water Palm8. Yoon Daeho — Black Iron Fist9. Park Minji — Thousand Mile Step10. Jeong Taewoo — Blazing Fist11. Unknown — technique unspecified
"Who is number eleven," said Han-Ho.
"They declined to provide information," said Park Sung-Jin. "The Sword Saint said to include them anyway. He did not explain why."
Han-Ho made a note.
Appointment eleven: unknown. Technique unspecified. Sword Saint vouched. Keep slot.
"The intake desk," said Han-Ho. "Can Ms. Yoon add a preparation station. Each martial artist should have their technique qi-encoded in a transferable medium before the appointment. Otherwise the cleaning session requires them to be physically present and actively projecting which reduces efficiency."
Park Sung-Jin wrote this down.
"I will tell Ms. Yoon," said Park Sung-Jin.
"She will have it set up before two PM," said Han-Ho.
"She will have it set up before noon," said Park Sung-Jin.
She had it set up before ten AM.
The Sword Saint arrived first.
Not at his appointment slot.
At one fifty PM.
Twenty minutes before the first appointment.
He came to the rooftop where Han-Ho was doing the pre-session assessment of the Dragon Vein Gate residue.
"You are early," said Han-Ho.
"I wanted to observe the preparation," said the Sword Saint.
"There is no preparation," said Han-Ho. "I assess each technique. I clean what needs cleaning. I move to the next."
"No warm-up."
"The technique is always ready," said Han-Ho. "Warming up is for techniques that are inconsistent. Mine is consistent."
The Sword Saint looked at him.
"In ninety years of sword training," said the Sword Saint. "I have never met a practitioner who did not warm up."
"I clean things," said Han-Ho. "It is the same process every time. Starting from outside. Working inward. No unnecessary movements. No variation." He looked at the Gate. "The warm-up is the work."
The Sword Saint was quiet for a moment.
"Yes," he said. "I think you are right."
They went to the sixth floor.
The technique cleaning sessions ran from two PM to four PM.
Han-Ho sat at a table Ms. Yoon had arranged.
The qi-encoded mediums were already there. Small jade tablets. Each one carrying the structural encoding of a martial artist's primary technique. Ms. Yoon had figured out the encoding process from the old man's data and had developed a standardized protocol for it by Tuesday evening.
Park Sung-Jin was at the door managing the queue.
Han-Ho picked up the first tablet.
River That Cuts Heaven. Follow-up assessment.
He pressed his hand against it.
Read it.
Clean.
The cleaning he had done on Monday was holding. No new contamination accumulation in two days. The technique was performing at correct efficiency.
"Clean," said Han-Ho to Wei Liang. "No new accumulation. The Dragon Vein activation ambient improvement is maintaining the technique state."
"How often should I return for assessment," said Wei Liang.
"Monthly initially," said Han-Ho. "If the ambient mana quality continues improving the frequency can reduce. Eventually the technique will maintain itself without external cleaning."
"Maintain itself," said Wei Liang.
"A clean technique in a clean environment stays clean," said Han-Ho. "Same principle as a clean floor. If the ambient mana is clean and the practitioner's qi is clean the technique does not accumulate contamination."
Wei Liang looked at his tablet.
"In ninety years," said Wei Liang. "I have assumed the accumulation was permanent. A feature of long use. Not contamination."
"Everything that accumulates incorrectly is contamination," said Han-Ho. "The length of time does not change that."
Wei Liang was quiet.
"Monthly assessment," he said.
"Yes," said Han-Ho.
Wei Liang left.
The sessions continued.
Mountain Heart Sutra: dense accumulation from fifty years of training in the sect's mountain valley where a Dragon Vein junction had been partially blocked. The blocking had contaminated the ambient qi of the entire valley for generations. Every technique trained there carried the valley's contamination signature.
Han-Ho cleaned it.
Made a note.
Mountain Heart Sutra: valley contamination signature. Sect location directly above partially blocked Dragon Vein junction. Activation may have cleared it but historical accumulation in techniques remains. Recommend sect leader file report for full valley technique assessment. Significant remediation possible.
Iron Body Foundation: this one was interesting. The qi hardening technique — similar to Hwang Ryeok's but more refined. The contamination was minimal. The technique was in good condition. But the fundamental structure of the technique had a micro-inefficiency that was not contamination. It was original. Built into the technique itself.
Han-Ho cleaned the contamination.
Then he pressed his hand more firmly against the tablet.
Read the original structure.
The micro-inefficiency was in the qi circulation path of the third reinforcement layer. A slight redundancy. Not harmful. Just — not optimal.
Han-Ho hesitated.
Then he addressed it.
Not cleaning. Slightly different. The way you straighten a surface that is clean but not quite level.
He handed the tablet back to Pak Junseok.
"The contamination is cleared," said Han-Ho. "I also addressed a minor structural inefficiency in the third reinforcement layer. The technique was not contaminated there. But the circulation path had a slight redundancy from the original design."
Pak Junseok took the tablet.
Read his own technique.
His eyes went wide.
"What did you do," said Pak Junseok.
"I straightened it," said Han-Ho. "The redundancy was small. The correction is small. The efficiency improvement should be approximately three percent."
Pak Junseok looked at the tablet.
At the technique that his sect had been practicing for four hundred years.
With a structural inefficiency in the third reinforcement layer that had apparently been there since the original design.
That Han-Ho had just fixed.
In approximately forty seconds.
"Four hundred years," said Pak Junseok.
"Yes," said Han-Ho. "The original designer probably intended the current path. But the optimal path is slightly different. Small correction."
"Small," said Pak Junseok.
"Yes," said Han-Ho. "Three percent."
"Three percent," said Pak Junseok. "In an Iron Body technique. That is not small."
Han-Ho thought about this.
"Relatively small," said Han-Ho.
Pak Junseok sat down.
Not because he was tired.
Because sometimes information required sitting.
Han-Ho moved to the next tablet.
The Sword Saint was watching from the side.
He had stayed for the entire session.
Not in the queue. Just watching.
By appointment seven he turned to Ms. Yoon who was managing the documentation at a side desk.
"He fixed the Iron Body technique," said the Sword Saint.
"Yes," said Ms. Yoon.
"Not just cleaned it. Fixed an original design inefficiency."
"Yes," said Ms. Yoon.
"That technique is four hundred years old."
"Yes," said Ms. Yoon.
"He fixed a four hundred year old design inefficiency in forty seconds."
"Yes," said Ms. Yoon, writing something in her file.
"And he called it relatively small."
"He calls most things relatively something," said Ms. Yoon. "It is how he contextualizes. Everything is relative to the job. The job is what matters."
The Sword Saint watched Han-Ho move through appointments eight and nine with the focused efficiency of someone running a route. Same approach every time. Read the tablet. Assess the contamination. Clean from outside in. Address any structural issues. Note the findings. Next.
"He is not just cleaning techniques," said the Sword Saint.
"No," said Ms. Yoon.
"He is improving them."
"When improvement is available yes," said Ms. Yoon. "He will not improve something that does not need improvement. But if the surface is clean and an inefficiency is visible he addresses it. Same principle as the cleaning." She paused. "He filed a report about it last week. The report said: correct not better. But correct sometimes means better when better was always what correct was supposed to be."
The Sword Saint looked at her.
"You understand him very well," said the Sword Saint.
"I have been building his file for four years," said Ms. Yoon. "You develop an understanding."
The Sword Saint looked at Han-Ho.
"How long," said the Sword Saint. "Until word spreads through the martial world that he can fix techniques."
Ms. Yoon looked at her appointment system.
At the notes column.
At the eleven appointments that had filled in four hours.
"It already has," said Ms. Yoon.
Appointment eleven.
The unknown.
Technique unspecified.
The door opened.
Han-Ho looked up.
The person who came in was not a martial artist.
Not in the conventional sense.
Old. The specific old that made the old man's approximately sixty look recent. This person looked approximately eighty but with the same quality of having stopped aging at eighty and remained there for a very long time.
Plain robes. No sect markings. No formal bearing.
The kind of person who had stopped performing their credentials so long ago that the absence of performance had become its own statement.
They sat across from Han-Ho.
Looked at him.
Han-Ho looked at them.
"You have no tablet," said Han-Ho.
"No," said the person.
"The appointment system requires a qi-encoded tablet for—"
"I know," said the person.
"Then—"
"I did not come for a technique cleaning," said the person.
Han-Ho made a note.
Appointment eleven: present. No tablet. Not here for technique cleaning. Purpose unknown. Assessing.
"What did you come for," said Han-Ho.
The person looked at him for a long moment.
With the specific focused attention of someone who has been looking for something for a very long time and is not entirely sure they have found it but is not entirely sure they have not.
"I came to see you," said the person.
"You could have seen me at the Registry intake desk," said Han-Ho.
"I did not want to see you at a desk," said the person.
"Then why use the appointment system."
"Because the Sword Saint said it was the correct protocol," said the person. "And I follow correct protocol."
Han-Ho looked at them.
"Who are you," said Han-Ho.
The person was quiet for a moment.
"In the martial world," they said. "I am called the Formless Sage."
The Sword Saint, still in the room, became very still.
Ms. Yoon's pen stopped moving.
Park Sung-Jin, at the door, looked at the Sword Saint with a question on his face.
The Sword Saint's expression answered it.
The answer was: yes. That is who you think it is.
Han-Ho made a note.
Appointment eleven: Formless Sage. Martial world. No sect. No technique tablet. Purpose: to see me. Filing.
"You are very old," said Han-Ho.
"Yes," said the Formless Sage.
"Older than the old man."
"Yes."
"What realm."
The Formless Sage was quiet.
"I am beyond the realm system," said the Formless Sage.
Han-Ho looked at them.
"Beyond the Life and Death realm," said Han-Ho.
"Yes."
"The Divine realm."
The Formless Sage did not respond to this.
Which was a response.
Han-Ho made a note.
"You came through the Dragon Vein Gate," said Han-Ho.
"Yes."
"You left residue."
"...Yes."
"I will need to clean it after the session."
The Formless Sage looked at him.
"Yes," said the Formless Sage. "I imagine you will."
Han-Ho looked at his appointment list.
At the time.
At the remaining sessions.
"The appointment was for two PM to four PM," said Han-Ho. "You came at three forty seven. You have thirteen minutes."
"I know," said the Formless Sage.
"What do you want to know in thirteen minutes."
The Formless Sage looked at Han-Ho.
At the work uniform.
At Moru on his shoulder.
At Kjor on his other shoulder.
At River in the bag pocket.
At the notebook.
At the appointment list.
At the clean table.
At everything that was Han-Ho in the specific complete way that someone who has been alive since before the realm system existed looks at everything.
"I wanted to know," said the Formless Sage, "if you were real."
Han-Ho looked at them.
"I am a Mana-Janitor," said Han-Ho. "Rank F. One skill. I am very real."
The Formless Sage was quiet.
Then they said: "Yes. I think you are."
They stood.
Bowed.
Not the formal sect bow.
A different bow.
The bow of someone who does not bow to anyone bowing to the specific exception.
"I will not take more of your time," said the Formless Sage.
"The residue zone is three meters from the Gate," said Han-Ho. "Please step back when you go through."
"I will," said the Formless Sage.
They left.
The room was quiet.
Ms. Yoon looked at her file.
Added an entry.
The entry was very short.
It said: The Formless Sage came to confirm Han-Ho was real. Filed.
The Sword Saint looked at Han-Ho.
Han-Ho was reading the next appointment note.
There was no next appointment. The session was over.
He was reviewing the notes from the afternoon.
"Han-Ho," said the Sword Saint.
"Yes."
"The Formless Sage."
"Yes."
"Do you know who that is."
"They told me," said Han-Ho. "The Formless Sage. Beyond the realm system. Probably Divine realm or approaching it."
"They are the oldest living martial artist in our world," said the Sword Saint. "Older than the Unmoving Mountain by several thousand years. They have not left their mountain in five hundred years. They came through a dimensional Gate to a building in northern Mapo-gu to confirm you were real."
Han-Ho made a note.
Formless Sage: oldest living martial artist in martial world. Older than old man by several thousand years. Five hundred year reclusion ended to confirm I was real. Notable. Filing.
"And," said the Sword Saint. "What do you think about that."
Han-Ho closed his notebook.
"I think I need to clean the Gate residue," said Han-Ho. "They came through without stepping back from the residue zone."
The Sword Saint looked at him.
"That is what you think about the oldest martial artist in the world coming out of five hundred years of reclusion to see you."
"They left residue," said Han-Ho.
"HAN-HO—"
"The residue does not clean itself."
The Sword Saint looked at Ms. Yoon.
Ms. Yoon was writing in her file.
She was smiling.
Very slightly.
The specific smile of someone who has known something for a very long time.
