The figure beyond the marker remained in the mist while the whole village learned how long a person could stand without moving before stillness became a threat.
Shen Qing kept his sword low. He had once told Xiulan that men who raised weapons too early usually ended by using them. She had thought it sounded like professional superstition. Now she watched the tendons in his wrist and understood that restraint could also be training.
"Range," Shen Qing said.
Lan Jue checked the nearest survey plate. "Twenty-three paces if the road and the marker agree."
"Do they?"
"The readings diverge by eleven paces and are still moving."
"Then nobody crosses twelve." Shen Qing signaled two watchers into position. "Tell me when the number changes."
"That is an order I can satisfy."
The figure raised one hand again.
Keshi had stopped crying. That worried Xiulan more than the crying had. The boy stood beside his mother with both fists closed against his chest. "Anu never did that."
"No one said it was Anu," Xiulan told him.
"I know." He swallowed. "I am saying she would wave badly."
Qiao Rui, who had slipped out of the shrine despite Qiao Ming's instructions, whispered, "How do you wave badly?"
Keshi demonstrated without taking his eyes from the mist. His version involved too much elbow.
For one absurd moment, several frightened adults watched.
Then the road marker knocked.
Three. Two. Three.
Keshi jerked toward it.
The figure in the mist lowered its hand.
A second pattern answered from beneath the old well.
Two. Three. Two.
The boy stared at Tianhui. "That was mine."
Tianhui was already moving.
Slowly, because his body required honesty even when the situation did not. His first channel remained warm from training. Thirty-six controlled breaths had left his shoulder trembling. He crossed the courtyard while Lan Jue brought the response plate and Shen Qing repositioned two watchers between the village and the northern marker.
"Do not answer yet," Tianhui said.
Keshi's face tightened. "You told me to answer last time."
"I had fewer unknowns last time."
"My friend is still missing."
"Your count is unchanged," Tianhui said.
"Then stop talking as if waiting improved it."
Tianhui stopped beside him. The boy was not being clever. He was angry, and anger had made the arithmetic simple.
"Your arithmetic is sound. Give Lan Jue ten heartbeats."
Lan Jue crouched by the well and rotated the response plate a fraction. "Twelve. The plate is still settling, and I will not shorten evidence to protect his estimate."
Keshi muttered that adults invented numbers when they wanted children to wait.
Qiao Rui nodded in fierce agreement.
The marker knocked again.
Three. Two. Three.
This time another sound rode beneath it: a child shouting from very far away.
Keshi dropped to his knees.
"Anu!"
The road opened without permission.
Mist spilled over the northern stones. The figure beyond the marker vanished behind it. Every survey plate in the courtyard rang once, sharp enough to make people cover their ears. Tianhui felt relation pull at his channel.
He could have opened Branch-Sight fully.
The urge came with the old sweetness. Thousands of futures waited a thought away: Keshi answering; Keshi silent; Shen Qing charging; the village evacuating; the mist entering; the marker breaking. Tianhui took only what he needed.
Seventeen branches.
Then he stopped.
The present returned with pain in his shoulder.
"Keshi," he said. "Answer her."
The boy did not ask why. He struck the stone with two knuckles.
Two. Three. Two.
The mist tore open.
For a heartbeat the north road did not lead north.
It opened onto a square.
The other Hejingshui.
People scattered beneath a sky the color of wet ash. Xue was near the well, shouting at someone Xiulan could not see. A child ran across the square.
"Anu!" Keshi screamed.
The girl heard him.
She turned.
The square split.
There was no flash. No explosion. One moment Anu was running toward the sound. The next, the road offered two equally convincing positions for her: one beside the false village well, one three streets farther east where a house should have stood.
Both girls stumbled.
Both shouted Keshi's name.
The opening shuddered.
Lan Jue swore and drove both palms onto the response plate. "Two relations are claiming the same reference."
"Can you hold both?" Shen Qing asked.
"For perhaps six seconds."
"That is not an answer I can use."
"It is the only one available."
Tianhui saw the two Anus and understood the trap before he understood the cause. If they pulled toward one position, the other weakened. If they tried to hold both, the road widened into something his single channel could not support.
Xiulan saw the calculation pass across his face.
"What can the rest of us hold?" she asked.
"Keshi's relation. Nothing else will remain stable long enough."
The boy was already kneeling at the marker.
"Which one is your friend?" Tianhui asked.
Keshi stared through the opening. "Both."
"Which relation can you name?"
"That does not make sense."
"I know. Answer anyway."
The Anu near the well was crying. The one in the eastern street had gone very still.
Keshi shook his head hard enough to send rainwater from his hair. "The mill weight."
Xiulan caught his shoulder. "What about it?"
"She cheated."
"Keshi."
"We were carrying it. Old Meng said whoever dropped it first had to clean the wheel pit. She put her end on the wall and said the wall was helping."
Across the road, the Anu near the well shouted, "It was helping!"
The eastern Anu shouted at the same time, "You agreed the wall counted!"
Keshi made a broken sound that might have been a laugh.
Tianhui felt the relation change.
There. Not identity. Shared event.
"Again," he said.
Keshi stared at him.
"Argue with her."
The boy's face twisted. "This is your plan?"
"It is the plan that exists."
Keshi slapped both hands on the marker. "You cheated!"
Both Anus answered.
The road buckled.
Lan Jue shouted, "Too much!"
Tianhui opened his channel.
Pain lanced through the shoulder. He ignored the old instinct to force more qi. Instead he let the living route bend the way Lan Jue had taught him. The current curved through scar tissue and entered the response plate.
He could not hold two people.
He could hold one relation.
That distinction mattered.
"Keshi," he said through clenched teeth. "Keep talking."
The boy swore at Anu with the inventiveness of a child who had been saving complaints for six days. The two girls answered over each other. One remembered the wall. One remembered Old Meng throwing a rag at them. One remembered Keshi falling into the wheel pit anyway. The memories overlapped, diverged, collided.
Tianhui stopped asking which girl was real.
He traced the event instead.
Mill. Iron weight. Mud. Two children lying to an old man. A friendship repeated often enough to survive catastrophe.
The road narrowed around that relation.
The false square steadied.
The eastern street did not.
Xiulan understood what was happening. "Tianhui."
"I know."
"If you stabilize one—"
"The other may move beyond reach."
Keshi heard.
"No."
Tianhui wanted another minute. Another hundred futures. A better answer.
He had none.
The eastern street was already breaking into grey rain. The Anu standing there looked toward the square and saw the other girl.
The two children saw each other across the split.
Neither screamed.
The eastern Anu lifted one hand.
The girl by the well lifted hers.
Tianhui closed his eyes for one heartbeat.
Then he chose the relation he could actually hold.
"Lan Jue. Narrow to the mill event."
"Understood."
"Shen Qing, get everyone away from the north plates."
"Moving."
"Xiulan—"
"I am here."
"Do not let Keshi stop talking."
She crouched beside the boy. "Tell her about the wheel pit."
Keshi was sobbing now. He kept talking.
The square snapped into focus.
The Anu beside the well fell to her knees.
The eastern street folded sideways and vanished.
No one crossed.
No body appeared in Hejingshui. There was no miracle to misunderstand.
There was only one visible child on the far side, still alive, and one relation Tianhui had failed to keep.
The opening collapsed.
Tianhui's channel went dark.
He hit the ground on one knee.
Keshi grabbed the marker with both hands. "Anu!"
A voice came faintly through the stone.
"I am here."
The boy pressed his forehead against it.
"Which one?" he asked.
Silence.
Then, from very far away, another knock answered.
Three.
Pause.
Two.
Pause.
Three.
The pattern came from somewhere other than the false village.
Tianhui remained on one knee and listened.
One Anu was still reachable.
The other had not become nothing.
At the northern boundary, the human-shaped figure had disappeared.
In the mud where it had stood, someone had written a single word in characters older than every house in Hejingshui.
