[NAME REQUIRED] The prompt had waited since before dawn.
Lin Fan had not answered it.
The dark stain on the paving stones outside his room had been washed twice, but a shadow of it remained.
Every time Lin Fan looked toward the courtyard, he saw the disciple from the previous night folding around a current that had never belonged in his meridians.
A correct answer, copied into the wrong body.
He had spent half the night building safeguards.
By morning, the model contained more ways to refuse a user than ways to help one.
Then someone knocked.
Sun Yu stood beyond the door, a faded red cord wound around two fingers.
He was twenty, though three years in the outer court had left him stooped, his robe neatly patched, and his hopes reduced to numbers: two meals, four hours of sleep, six contribution points for hauling spirit-water jars.
“Wei Kang said you needed a second user.” “I did,” Lin Fan said.
Sun Yu glanced past him at the papers.
“Did?” “The method is unverified.” “That was true yesterday.” “Yesterday, no one had been hurt by copying me.” Sun Yu’s fingers tightened around the cord.
“That is why I came.” Lin Fan looked at him.
“Nine people came here for your answer,” Sun Yu said.
“You were the only one who told them you might be wrong.” The words landed more heavily than praise.
Sun Yu had a low-grade mixed wood-and-water root.
The testing crystal recognized it.
The outer-court registry recognized it.
Instructors still spoke about it as though recognition were a courtesy.
Twenty-seven supervised circulation tests filled his record.
Twenty-seven results read the same.
Zero retention.
Two years earlier, Sun Yu had spent eighteen months of contribution points on one incense stick in the Lesser Gathering Chamber.
After six failed circulations under an examiner’s eyes, he had returned the token before the incense burned out.
“I stopped cultivating for four months,” he said.
“Why did you start again?” Sun Yu unwound the cord.
“Because during the last failure, I felt something reach the root.” “The record says there was no contact.” “The record says a lot of things.” There was no anger in his voice.
That made it sharper.
“I do not trust you because I think you are right,” Sun Yu said.
“I trust you because I watched you stop when you might be wrong.” Inside Lin Fan’s mind, HEAVEN-01 answered before he could.
Transferability data is insufficient.
Predicted benefit does not justify exposure of a non-terminal subject.
Lin Fan turned inward.
“Every first validation begins without transfer data.” The first user was yourself.
This is different.
“Because he can refuse?” Because your first modifications occurred under terminal constraints.
Sun Yu still possesses a safer option.
“Refusal gives him another zero.” Zero retention is not physical injury.
The statement was true.
That was what made it difficult.
Lin Fan looked again at the old bloodstain, then at Sun Yu.
“Deacon Qiu sets the limits,” he said.
“If he refuses, we do not test.
If he stops, we stop.
If you hide pain or change an instruction, the test ends.” Sun Yu nodded too quickly.
“That was not agreement,” Lin Fan said.
“That was desperation.” The cord went still between Sun Yu’s fingers.
After a moment, he nodded again.
This time, he understood what he was accepting.
Deacon Qiu refused before Lin Fan finished the proposal.
“No.” They stood in the Healing Pavilion’s smallest diagnostic chamber.
Sun Yu waited near the wall.
Wei Kang had brought the records.
Lin Fan had brought the model.
Qiu had brought neither patience nor the illusion that caution made him popular.
“Minimum input,” Lin Fan said.
“No pills.
No spirit stones.
One variable per attempt.” “No.” “You control the formation.” “I controlled it last night.” Lin Fan fell silent.
Qiu opened Sun Yu’s file and ran one finger down the column of failed tests.
“Seventeen years ago, my senior devised a faster method for opening damaged meridians,” he said.
“The first eight patients improved.
On the ninth, the new route collapsed and took three healthy channels with it.” Sun Yu stopped twisting the cord.
“I held that boy still while my senior tried to save his cultivation.
He could not.” Qiu closed the file.
“New methods do not frighten me.
Early success does.” “Then do not let us call one success proof,” Lin Fan said.
Qiu studied him for several breaths.
“And if you want the test to succeed?” “Stop it.” “If he wants it to succeed?” “Stop it.” Qiu looked at Sun Yu.
“If either of you argues after I stop the formation, neither returns.” Sun Yu bowed.
Only then did Qiu place his hand on the control crystal.
Lin Fan reached for the first record.
His hand stopped.
For one breath, the empty platform held the shape of the disciple who had fallen the night before.
Qiu waited until Lin Fan could write the date.
“If this needs a name in my record, give it one.” The empty field appeared again.
Lin Fan had once given a grand name to an intelligence built to replace human work.
This method deserved nothing grand.
It was only a process for asking a body what it could safely do.
“Algorithm Cultivation Model,” he said.
[NAME ACCEPTED] [ALGORITHM CULTIVATION MODEL] [TRANSFERABILITY: UNVERIFIED] No power entered the room.
No ancient inheritance opened.
Qiu adjusted the formation by hand.
“Sit.” The standard Azure Cloud Basic Breathing Technique failed exactly as Sun Yu’s records predicted.
He inhaled deeply, as the manual required.
Five threads of qi entered his chest.
His narrow meridians could not carry them together.
They crowded beneath his lungs, scattered into useless branches, and vanished before reaching the lower dantian.
Heat gathered beneath his sternum, then went cold in his fingertips when the current vanished.
[INPUT: 5.1 UNITS] [RETENTION: 0.0%] Sun Yu opened his eyes.
There was no surprise in them.
“First failure,” Lin Fan said.
“Excessive input.” “I followed the manual.” “The manual says to breathe deeply.
It does not define deeply for your body.” Qiu lowered the chamber’s qi supply.
The second attempt used a single thread.
Sun Yu guided it down the standard route.
Without the pressure of four additional currents, the qi traveled farther.
It reached the constricted junction beneath his left lung and stopped.
He pushed.
The thread folded against the obstruction and dispersed.
The failed thread left a bitter-metal taste at the back of his tongue.
[ROOT CONTACT: NONE] [RETENTION: 0.0%] Sun Yu’s jaw tightened.
“Second failure,” Lin Fan said.
“Unusable route.” “So less qi changes nothing.” “It separated two problems.” Wei Kang set the two records beside each other.
“Too much input hid the obstruction.” Lin Fan pointed to a minor channel curving around the left lung.
The standard manual classified it as a leakage path because it lost nearly half the current passing through it.
“Use this branch.” Sun Yu stared at him.
“That route wastes qi.” “The direct route wastes all of it.” For the third attempt, he drew one thread and let it drift sideways.
The current entered the minor channel.
It weakened as it curved around the obstruction, but it did not stop.
Below the lung, it rejoined the primary meridian and touched the faint branches of Sun Yu’s spiritual root.
The pavilion crystal pulsed.
[ROOT CONTACT: ESTABLISHED] Sun Yu made a sound too small to be a laugh.
For three years, every instructor had told him to pull harder, hold longer, and endure more.
The first response from his root broke something loose behind his ribs.
He seized the returning current.
“Release it,” Lin Fan said.
Sun Yu inhaled again.
The second current entered before the first had cleared the narrow branch.
Lin Fan’s model assumed a recovery interval.
Sun Yu’s hope erased it.
The two currents struck beneath his lung and reversed.
Pale blue lines on the diagnostic formation flared red.
Qi kicked upward toward the heart meridian.
Sun Yu doubled over.
Qiu cut the chamber input.
The current already inside him kept moving.
[FLOW REVERSAL DETECTED] [SAFE ROUTE LOST] Lin Fan crossed one step toward the platform and stopped.
If he touched the wrong channel, he would add a third force to a system already out of control.
Last night’s disciple flashed across his mind: blood on stone, one breath between pain and permanent damage.
Sun Yu’s pulse stumbled.
“Left branch,” Lin Fan said.
“It has not reached the primary heart channel.
Vent through the shoulder junction.” Qiu was already moving.
A silver needle entered below Sun Yu’s collarbone.
Qiu turned it once, opened the minor channel, and struck the platform with his free hand.
The formation pulled.
Qi burst from Sun Yu’s shoulder in a spray of blue light.
He collapsed forward, coughing.
A thin line of blood ran from one corner of his mouth.
Then his pulse steadied.
No one spoke.
The first thing Lin Fan felt was relief.
The second was the knowledge that relief had arrived one breath from being useless.
The user violated the defined recovery condition.
“The condition existed in the model,” Lin Fan replied silently.
“Not in him.” Human compliance cannot be guaranteed.
“Then the model is incomplete.” Qiu withdrew the needle.
His hand was steady, but his face had lost its usual color.
“The test is over.” “Yes,” Lin Fan said.
Sun Yu looked up.
“I can continue.” “No.” The answer came from Lin Fan before Qiu could give it.
Anger sharpened Sun Yu’s face.
“The root responded.” “And you nearly drove the next current into your heart.” “I know what I did.” “You know now.” Sun Yu tried to rise.
Pain folded him back onto one hand.
Lin Fan crouched outside the platform boundary.
“Last night, someone was hurt because he copied an answer I had not made safe.
Today, you were hurt because my model treated your choice as if it would remain constant.” “I changed the instruction.” “I failed to design for the moment you would want to.” Sun Yu looked away.
Qiu gave him water and ordered bed rest until morning.
The model, the records, and the unnamed future of algorithm cultivation left the chamber with Lin Fan.
The third failure had not been input or route.
It had been a person reaching the first sign of hope after three years without it.
HEAVEN-01 reviewed every measurement twice.
Emotional response cannot be modeled with current data.
“Then we do not predict it.” Clarify.
“We assume it will happen.” Lin Fan made every root response trigger a mandatory recovery interval.
Pulse, meridian pressure, and breathing—not the user’s confidence—had to return to baseline.
No concealed pain.
Then: The user may end a test without losing the right to return.
Refusal remained part of the method.
Now it belonged to the user too.
Near midnight, Qiu found him revising the record.
“You are still trying to make it succeed,” the deacon said.
“I am trying to make the next failure survivable.” Qiu read the new conditions.
“Better.” It was not approval.
From Qiu, it was enough.
At the outer-court records hall, a red line crossed Elder Du’s archive stone and bypassed the routine filing queue.
The Healing Pavilion reported a flow reversal during an approved experiment.
Beneath it sat Sun Yu’s ordinary root classification, a route marked INVALID, and a root response the same archive said should not exist.
The contradiction forced open a live review channel.
Elder Du called for all twenty-seven previous records and left the channel open.
If Qiu allowed another attempt, he would receive the result as it happened.
Sun Yu returned after sunrise.
The red cord was no longer wound around his fingers.
He laid it beside the control crystal.
“I left the Gathering Chamber before my time ended,” he said.
“Everyone thought I quit because I was ashamed.” “Were you?” “Yes.” He looked at the platform.
“But I came back to cultivation because I had felt the root once.
Yesterday, I felt it again.” Qiu watched him carefully.
“Is this your last chance?” Sun Yu shook his head.
“No.
If you stop me, I leave.
If the model fails, I come back only if you permit it.
I want to continue because we found something the old test did not.” This time, Qiu accepted the answer.
He allowed one attempt.
Sun Yu sat on the platform.
Lin Fan remained outside the boundary.
Wei Kang opened a fresh record beneath the twenty-seven old ones.
One thread entered.
Sun Yu stopped inhaling.
The qi moved into the leaking branch beneath the left lung.
He let it weaken.
He did not force it toward the blocked route.
It touched the root.
The crystal pulsed.
Desire crossed Sun Yu’s face so openly that Lin Fan could see the next mistake before it happened.
Sun Yu closed his hands.
Then opened them.
He waited.
His pulse slowed.
The pressure beneath his ribs fell.
Only when Qiu gave a single nod did Sun Yu guide the returning fragment downward.
The thread passed the lower junction and entered the dantian.
Most of it faded.
Sun Yu did not chase it.
He exhaled and allowed what his root could not hold to leave.
A fragment remained.
Small.
Weak.
No brighter than warmth left in a cup after the tea was gone.
But it remained through one heartbeat.
Then two.
The pavilion crystal glowed.
[COMPLETE CIRCULATION: CONFIRMED] [EXTERNAL SUPPORT: NONE] [RETENTION: 1.2%] The number left the chamber before anyone inside it moved.
Qiu checked the formation.
Wei Kang checked the record.
Then Qiu opened Sun Yu’s old file and placed the final page beside the new one.
Twenty-seven official tests.
Zero point zero.
Yesterday’s baseline.
Zero point zero.
One point two was not fast.
It was not powerful.
It would not impress a talented disciple whose root retained ten times as much without thought.
It was not zero.
For the first time, the number proved that something had stayed.
Sun Yu stared at the crystal.
“Read it again.” Qiu’s voice was quieter than usual.
“One complete unaided circulation.
Retention: one point two percent.” Sun Yu closed his eyes.
The tears came without sound.
At fifteen, he had been called limited; at seventeen, useless; at eighteen, told to stop wasting sect resources.
For three years, every official measurement had reduced his effort to the same empty number.
Now the number had changed.
“Is that enough?” he asked.
“Enough to measure,” Qiu said.
“Enough to repeat.
Not enough to call proven.” Sun Yu laughed once.
The sound broke in the middle.
“Then we repeat it.” “Tomorrow,” Lin Fan said.
Sun Yu looked offended.
“Success is slow.” “Safe success is.” Colorless text appeared at the edge of Lin Fan’s vision.
[SECOND USER DETECTED] [ALGORITHM CULTIVATION MODEL] [TRANSFER RESULT: PARTIAL SUCCESS] [USER CONDITION: STABLE] Transfer observed.
Safety remains unverified.
“I know.” The model had not repaired Sun Yu’s root or made him talented.
It had only helped one weak root keep a fraction of what it could already touch.
That was all.
For now, it was enough.
Qiu sealed the record before the second evening bell.
The original remained locked in the Healing Pavilion.
Everyone present was ordered to speak of nothing until the result had been repeated.
Before sending the copy to Elder Du, Qiu pressed it into the pavilion archive.
The formation read Sun Yu’s name, his root classification, and the twenty-seven previous results without hesitation.
Then it reached the final page.
[REGISTERED ROOT: LOW-GRADE MIXED WOOD/WATER] [HISTORICAL RETENTION: 0.0%] [OBSERVED RETENTION: 1.2%] The blue script went dark, returned, and attempted the comparison again.
[RESULT OUTSIDE REGISTERED PATTERN] [CLASSIFICATION: UNRESOLVED] [SECONDARY REVIEW REQUIRED] Qiu watched the last line remain above the archive stone.
The formation did not understand what had happened.
It understood that its old answer was no longer sufficient.
Silence lasted until supper.
By midnight, Cao Jin had heard three versions: Sun Yu completed ten circulations, his root transformed, and the useless disciple from the assessment had created a method for everyone the sect had written off.
Near the kitchens, Sun Yu heard two disciples argue over whether Lin Fan had found an ancient inheritance.
He held the faded red cord in one hand.
For years, useless had sounded like an ending.
Tonight, it sounded like a question.
High above the kitchens, the lamp in the outer-court records hall was still burning.
Elder Du placed Sun Yu’s file beside Lin Fan’s.
The first record described a spiritual root the sect could not classify and a circulation pattern the archive could not match.
That had been troublesome, but singular.
One disciple could be an accident, an unknown inheritance, or an error that had learned to survive its own damage.
The second record belonged to a low-grade mixed root already measured twenty-seven times by ordinary formations.
Nothing about Sun Yu was unclassifiable.
Only the result was.
“One point two percent,” Elder Du said.
Qiu stood across from him.
“One complete unaided circulation.” “One cycle is not proof.” “No.” Elder Du looked at the two files again.
“But it is transfer.” A thread of gold light crossed the ceiling and descended over the desk.
The archive’s unresolved classification had triggered a review request from the inner court.
An elder’s seal burned at its center.
Full cultivation record requested.
Qiu read the words.
“Will you release it?” “After Sun Yu repeats the result.” Elder Du covered the request with his hand, but he did not dismiss it.
Until that evening, the sect could treat Lin Fan as an exception.
Sun Yu had made that explanation smaller.
Elder Du opened the reply field and wrote one sentence.
A second cultivation model has appeared in the outer court.
Before the ink dried, the gold seal carried the sentence toward the inner court.
