The gray service robe didn't change Lin Wuchen's bones.
It only changed how people looked at him.
When he stepped out of Gu Yan's courtyard dressed in cleaner cloth, the servants in the corridor lowered their eyes a little faster. The outer boys he passed later would stare a little longer. Everyone understood one thing the sect taught well.
If someone higher marked you, you became dangerous to touch.
Wei led him through the inner service corridor without hurry.
"You're a runner now," Wei said flatly. "That means you're always in the way."
Wuchen bowed slightly as he walked. "Yes."
Wei stopped at a side gate that led into a quieter portion of the inner halls. Two stone lanterns stood there, glass clean, flame steady. A wooden plaque hung beside the gate with a single character carved deep.
Medicine.
Wei said, "Inner Apothecary."
Wuchen's stomach tightened.
The apothecary wasn't just herbs and salves. It was where elders and inner disciples bought the right kind of pain relief and the wrong kind of poison.
Wei looked at him. "Senior Brother Gu wants two things," he said. "A wound paste and a breath pill."
Wuchen kept his voice calm. "For Senior Brother Gu?"
Wei's gaze stayed flat. "For his use," he replied. "Don't ask who swallows."
Wuchen bowed. "Understood."
Wei pushed the gate open and motioned Wuchen inside.
The inner apothecary hall was warm.
Not cozy warm. Furnace warm. A steady heat that smelled like dried roots, bitter bark, and alcohol used for cleaning tools. Shelves lined the walls. Jars sat sealed with wax. A low counter ran along one side where a thin old woman ground herbs with a stone pestle, her movements slow and exact.
Her eyes lifted when they entered.
Not welcoming. Measuring.
Wei bowed slightly. "Auntie He," he said.
So not a servant.
Auntie He looked at Wei, then at Wuchen's gray robe. Her mouth tightened. "Gu Yan's runner," she said, not asking.
Wuchen bowed. "Yes."
Auntie He snorted. "He's collecting strays," she muttered. Then she turned her pestle once more and set it down like it was punctuation.
Wei spoke without softness. "Two items," he said. "Stone-marrow paste, and three breath pills."
Auntie He's eyes narrowed. "Stone-marrow paste isn't cheap," she said. "And breath pills are rationed during Beast Tide Season."
Wei's gaze didn't change. "Gu Yan pays," he said.
Auntie He tapped the counter. "With what?" she asked.
Wei looked at Wuchen. "You," he said. "You pay."
Wuchen's stomach dropped. "Silver?"
Wei reached into his sleeve and tossed Wuchen a small pouch. It clinked.
Wuchen caught it with both hands and bowed. "Yes."
Auntie He watched Wuchen's hands the way Auntie Mu had: not the money, the grip.
"Count," she said.
Wuchen opened the pouch and counted silently, placing coins on the counter one by one. He didn't rush. Rushing looked greedy. Hesitating looked weak. He kept his face blank.
Auntie He nodded once, satisfied.
She disappeared behind a curtain and returned with a small ceramic jar sealed with pale wax and three tiny pills in a lacquered box.
She set them down and said, "Paste is for flesh. Pills are for lungs. Don't confuse them."
Wuchen bowed. "Understood."
Wei reached for the items.
Auntie He slapped the counter lightly, stopping him. Her eyes moved to Wuchen again. "Boy," she said, "hold out your hand."
Wuchen froze for half a breath, then extended his right hand, palm up.
Auntie He pinched his wrist with cold fingers and pressed. A faint pulse of pressure slid into his arm like a needle testing fabric.
Her mouth tightened. "Thin," she muttered, echoing Elder Qin. "Too thin to waste."
Wei's expression didn't change, but his eyes sharpened slightly. He had heard it.
Auntie He looked up at Wei. "Gu Yan wants a tool," she said. "He should feed it."
Wei said flatly, "He does."
Auntie He snorted and reached under the counter, pulling out a tiny paper packet and flicking it onto Wuchen's palm.
Wuchen caught it, startled. It was light, warm, and smelled faintly bitter.
"What is this?" Wuchen asked quietly.
Auntie He's one eye narrowed. "Bone-warming powder," she said. "One pinch in hot water at night. It won't make you strong. It will keep you from breaking."
Wuchen's throat tightened.
Free things in the inner hall were hooks. But refusing was also a statement.
He bowed. "Gratitude."
Auntie He waved him off. "Don't thank me," she said. "If you die too fast, Gu Yan comes back and bothers me."
Wei finally took the jar and pill box. "We're done," he said.
They left the apothecary hall and walked back into the corridor.
Wei spoke without turning his head. "You don't speak about what you heard," he said. "Auntie He's words aren't for the outer yard."
Wuchen bowed. "Yes."
Wei's pace didn't change. "Now," he said, "you deliver these to Senior Brother Gu."
Wuchen's stomach tightened a second time.
This was the first inner errand.
It looked simple.
But he already understood the trap inside it.
If the paste was wrong, if a pill was missing, if a seal was broken, Gu Yan wouldn't need to punish him loudly.
Gu Yan would just stop investing.
And in this sect, the only thing worse than being owned was being discarded.
