Gu Yan didn't send Wuchen to Han's clerk with a message.
He sent him with a body.
A body that would lie without paper.
By late afternoon, Wuchen's palms could hold warmth for three breaths and then let it spill like sweat. The trick was not to spill too cleanly. Clean leaking looked like technique. Ugly leaking looked like weakness.
Gu Yan wanted ugly.
"Don't be clever," Wei said as he walked Wuchen to the registry corridor. "Clever smells like effort."
Wuchen bowed. "Yes."
The registry hall was loud in its quiet way: brush-scratch, paper-flip, stamp-thud. Clerks sat behind desks like spiders, each with a small web of slips and seals.
Han's clerk was at the side desk again, fingers ink-stained, eyes tired and sharp.
He looked up when Wuchen bowed. "You," he said. "Gu Yan's runner."
Wuchen held a small stack of blank forms and an ink pouch as cover, like last time. Ordinary cargo.
The clerk's gaze flicked to the jade edge at Wuchen's cuff, then lingered on Wuchen's face.
"You've been moving a lot," the clerk murmured. Not accusation. Measurement.
Wuchen lowered his gaze. "This one carries errands."
The clerk's mouth twitched. "Everyone carries," he said. "Some carry trouble."
He leaned forward slightly. "Did you go out last night?" he asked softly.
Wuchen's stomach tightened.
So the unlogged night had still left a smell.
Not on paper.
In rumor.
Wuchen did what Gu Yan trained him to do.
He let the qi in his belly rise a thread up his arms, into his palms, then he let it leak out through his fingertips in a sloppy way. His fingers warmed. A faint tremor ran through them, real enough to look involuntary.
He bowed lower, shoulders slightly hunched. "This one… doesn't know," he said, voice small. "This one only follows orders."
The clerk watched Wuchen's hands.
His eyes narrowed.
He saw the warming fingers. The slight shake. The breath that wasn't fully steady.
He didn't have the skill to name it, but he had enough instinct to decide: still thin.
Still leaky.
Not dangerous.
The clerk snorted softly. "Too many boys get fed a grain or two and start thinking they're people," he muttered.
Wuchen kept his gaze down, letting the leak continue just a little too long so it looked like he couldn't stop it.
The warmth drained from his palms. The three grains in his belly felt lighter, as if he'd truly spilled something.
But it was controlled.
Gu Yan's performance.
The clerk's posture eased. "What do you want?" he asked.
Wuchen slid the blank forms forward. "These need the registry header stamp," he said quietly. "For courtyard supply records."
The clerk stamped without fuss, as if stamping was beneath him but still his pleasure.
As he did, he said casually, "Han is watching Ridge Patrol passes now," he murmured. "Boys think unlogged doors are clever. Han thinks clever is a confession."
Wuchen's throat tightened. "Yes."
The clerk glanced up. "If you're smart," he said softly, "you stay inside the walls. Outside is where people disappear and everyone pretends they don't."
Wuchen bowed. "This one understands."
The clerk handed the stamped forms back. "Go," he said. "And tell your master to stop stirring patrol. It makes paperwork messy."
Wuchen bowed and left, palms cooling, breath stacked again once he was out of sight.
He returned to Gu Yan and reported what mattered.
Not the stamp.
Not the clerk's boredom.
The question: Did you go out last night?
And the clerk's warning about unlogged doors being confessions.
Gu Yan listened, then smiled faintly. "Good," he murmured. "So the clerk smelled smoke, but he tasted weakness."
Wei's eyes stayed flat. "Painted."
Gu Yan nodded. "Painted," he echoed.
He looked at Wuchen, eyes bright. "Now you can be visible when it helps you," he said softly. "And invisible when it hurts."
Wuchen bowed, throat tight.
Because painted weakness wasn't freedom.
It was another skill inside the cage.
A prettier leash, woven into his own breath, so he could pull it tight on himself before anyone else had to.
