Gu Yan didn't ask whether the trap worked.
He asked who saw it.
Wuchen knelt in the pavilion and reported the courtyard wobble, the hand on the lacquer, the servants bowing too fast, the ridge-mark token flashing under lantern light. He reported Luo Ping's instant suspicion and Lan's calm interest.
Gu Yan listened with bright eyes and a faint smile, like a man enjoying a story he already knew the ending of.
When Wuchen finished, Gu Yan tapped the table once. "Good," he said softly. "Now Lan will dig."
Wei stood to the side, expression flat. "And the shadow will panic."
Gu Yan nodded. "Panic makes names fall out," he murmured.
Wuchen's throat tightened. "Senior Brother wanted a name."
Gu Yan smiled faintly. "Names aren't harvested the way herbs are," he said. "You don't pull. You water."
He gestured toward Wei. "Bring it," Gu Yan said.
Wei stepped forward and placed a thin folded slip of paper on the table. No emblem. No wax. The kind of note that could be carried in a mouth and swallowed if needed.
Gu Yan slid it toward Wuchen. "Return to the inner library," he said gently. "Ask the clerk for the Ridge Patrol roster for this month. Use this."
Wuchen's stomach tightened. "He'll refuse."
Gu Yan's eyes brightened. "He'll pretend to," he said. "Then he'll show you the part he wants you to see."
Wuchen swallowed. "And the shadow?"
Gu Yan smiled. "He'll hear you asked," he murmured. "And he'll come to you, because you're the only one who can erase his mistake."
Wuchen's chest tightened.
Gu Yan added softly, "Walk the same corridor again. The service courtyard. Let everyone see you go to the library."
Wuchen bowed. "Understood."
Gu Yan leaned forward slightly, voice gentle. "And Wuchen," he said, "if someone offers you a name in exchange for silence…"
He paused, letting the pause tighten like a rope.
"…you listen," Gu Yan finished. "Silence is also a currency."
Wuchen bowed lower. "Yes."
The inner library was dim and cool as always. The clerk behind the desk looked up when Wuchen approached, eyes tired and annoyed.
"You again," the clerk said.
Wuchen bowed and slid the plain slip across the desk.
The clerk read it once.
His eyes narrowed.
"Ridge Patrol roster," he murmured. "This isn't for runners."
Wuchen kept his gaze lowered. "Senior Brother Gu requests it for record comparison," he said quietly, repeating the rehearsed line.
The clerk snorted. "Everyone compares records when they want to cut someone," he muttered.
He stood, walked to a locked shelf, and pulled out a thin bamboo slip bundle tied with cord.
He didn't hand it over fully.
He opened it on the desk, keeping one hand on it like a leash, and let Wuchen see a list of names and small tokens marks.
"Look," the clerk said, voice low. "Don't touch."
Wuchen's eyes moved across the names, pretending to search slowly while his mind hunted for patterns.
Ridge Patrol didn't have many junior inner disciples.
A dozen at most.
Each name had a small mark beside it, indicating patrol route assignment.
Wuchen saw one mark that matched what he'd glimpsed on the corridor shadow's belt plaque: a ridge stamp shaped like a crooked line with a notch.
He read the name beside it.
Jiang Ren.
Wuchen kept his face dull.
He didn't react. Reaction would be noticed.
He bowed slightly. "This one has seen enough," he said.
The clerk tied the bundle again immediately and slid it back into the shelf. "If Gu Yan wants to cut Ridge Patrol boys," he said, "tell him to do it quietly. Loud cuts make elders ask questions."
Wuchen bowed. "Yes."
He left the library with the name inside his head like a stone.
Jiang Ren.
Now he needed to see if the name would walk to him, or if he would have to walk to it.
He took the corridor route back that passed the service courtyard again, letting his pace stay steady, letting his sleeve shift so the jade token edge showed.
He didn't have to wait long.
At the lantern bend near the courtyard, the shadow stepped out from behind a pillar.
Same clean robe. Same ridge-mark token.
Same faint smile, but tighter now.
"Runner," the man said softly.
Wuchen bowed. "Senior Brother."
The man's eyes narrowed. "You went to the library," he said.
Wuchen kept his gaze lowered. "This one had an errand."
The man stepped closer, voice still polite but thinner. "You're digging," he said.
Wuchen shook his head slightly. "This one doesn't dig," he said. "This one carries."
The man's smile twitched. "You carry trouble," he murmured.
He leaned in just enough that his voice could not travel. "You want my name," he said softly.
Wuchen's throat tightened. He didn't answer.
The man exhaled once, controlled. "Jiang Ren," he whispered, as if spitting something bitter.
So the name had walked to him after all.
Wuchen kept his face dull, but inside he felt cold satisfaction.
Jiang Ren continued, "Now you stop," he said. "You stop telling Gu Yan stories about my hands."
Wuchen's voice was quiet. "Senior Brother touched Lan's box."
Jiang Ren's eyes sharpened. "I steadied it," he hissed. "You made a show."
Wuchen bowed slightly, posture obedient. "This one is clumsy."
Jiang Ren's smile turned thin and dangerous. "Clumsy boys fall," he said.
Wuchen's fingers curled inside his sleeves.
Then Jiang Ren did exactly what Gu Yan had predicted.
He offered currency.
"I can make your life easier," Jiang Ren said softly. "Ridge Patrol can turn eyes away. Deacon Han can be distracted. Lan can be satisfied with other prey."
Wuchen kept his gaze down. "In exchange for what?"
Jiang Ren's mouth tightened. "Silence," he said.
Wuchen nodded slowly, as if considering.
He didn't say yes.
He didn't say no.
He said the safest thing: "This one obeys Senior Brother Gu."
Jiang Ren's eyes flashed. "Gu Yan isn't an elder," he said. "He's just an inner disciple with teeth."
Wuchen's voice stayed flat. "Teeth still bite," he said.
Jiang Ren stared at him, then smiled faintly again. "So you choose fear," he murmured. "Fine."
He stepped back, gaze cold. "Tell Gu Yan," he said softly, "that Ridge Patrol hands aren't as dirty as he thinks."
Wuchen bowed. "This one will report what this one sees."
Jiang Ren's smile vanished. He turned and walked away, posture controlled, but his steps were a fraction faster than before.
Wuchen watched him go without moving.
He had gotten the name.
He had gotten an offer.
Now he had to do the most dangerous part.
Carry the name back to Gu Yan without letting it become an invitation for Gu Yan to cut too loudly.
Because loud cuts made elders ask questions.
And when elders asked questions, runners were often the first ones to be silenced.
