The apprentice library was missing half its roof.
Rain came through the open rafters when the wind blew from the ridge. On dry days, the holes let in enough light for a worker to read without borrowing a lamp. Yan liked that. He could study before the night watch and still make it back to the labor quarters before the doors were checked.
He sat at the end of a long table with a public circulation diagram open in front of him. The page showed a simple route: draw qi from the breath, guide it through the chest, then let it settle below the navel. There were arrows but no words explaining why the path worked. A warning at the bottom said to stop if pain sharpened.
Yan copied the route onto a sheet of discarded wrapping paper. He had practiced the first turn after his shift and felt his channels tighten under his ribs. He had stopped before the ache became sharp. Now he planned to try again with fewer breaths and a looser shoulder.
“Those books aren’t for laborers,” said a voice behind him.
Yan covered the copy with one hand. The library attendant, Mo, had come around the shelves carrying a bundle of catalog slips. He was old enough that one eye watered in the cold, but he moved quietly and rarely missed a loose page.
“I thought the reading room was public.”
“The room is. The manuals are listed by class.” Mo tapped the board near the entrance. “Apprentices may read these during posted hours. Workers may use the primers when their overseer approves.”
“My overseer doesn’t approve of anything that takes me away from the waste yard.”
“That is not my problem.”
“No. It’s mine.” Yan pulled the paper free and showed the attendant the diagram. “This one was on the public table. I only copied it.”
Mo took the book and checked the catalog slip. He moved his finger down the list, then across a row that had been written in faded ink. “It’s filed under beginner circulation. Someone shelved it in the wrong place.”
“Does that make it public?”
“It makes it misfiled.” Mo studied Yan’s face. “You’re trying to cultivate?”
“I want a job that doesn’t send me through furnace ash all day.”
“Then learn before you practice. Bad circulation can injure you.”
Yan nodded. “I read the warning.”
Mo checked the clock over the door. “You can copy it while the room is open. Bring the book back before the watch changes. No other shelf.”
“That’s fair.”
Mo moved a stool to the table and sat where he could see the public shelves. “Show me what you’ve copied.”
Yan laid out his paper. Mo compared the arrows and marked a small turn near the abdomen. “You skipped this bend.”
“I thought it was a wrinkle in the page.”
“Then you’re fortunate you didn’t copy it as a straight line.”
Yan looked closer. The old ink had faded, and the diagram crossed a crease. He redrew the bend and checked it against the next page. “Would the route still work without it?”
“Work is a generous word.” Mo pointed to the warning. “The pressure would stop. If you forced it, it could hurt.”
Yan put down his brush. He had thought the pain came from not having enough qi. It might have come from following the route badly. “I’ll try again slowly.”
“Not here.”
“I meant later.”
Mo watched him copy the correction. “You don’t need to prove you can endure pain.”
“I’m not trying to.”
“Everyone says that right before they do.”
Yan smiled. “Then I’ll write it down so I can prove I stopped.”
Mo returned to his catalog slips. Yan finished the copy, adding the number of breaths he had used and where the ache began. The notes looked small beside the printed diagram, but they were his observations, not guesses. He put the original book back on the public table and waited until Mo checked it in.
The next evening, he returned during the posted hours. He had rested his shoulders before sitting, then followed one full turn without forcing the breath. The pressure caught again, but this time it eased when he followed the bend Mo had shown him. He managed one more turn before the ache returned. He stopped at once.
The gain was slight. Nothing rushed into him. No voice spoke, no hidden sign appeared. His channels remained his own, with the same limits they had the night before. But the second attempt had gone farther because he had followed the line more carefully. He marked the result beside the first: one additional turn, no sharp pain.
Mo checked his notes. “You’re measuring breaths?”
“I’m measuring where the route stops working.”
“That’s less likely to fool you.”
“Will you show me another diagram?”
“After you can explain this one.” Mo pulled the paper toward him. “Tell me where the qi enters.”
Yan traced the first arrow. “From the breath into the chest, then down.”
“And what do you do if the pressure catches?”
“Stop, loosen my shoulders, and check whether I’ve missed the bend.”
Mo nodded. “That’s the first useful answer I’ve heard today.”
He did not smile, but he returned the paper. Yan took it to the labor quarters folded inside his shirt. Ning was awake, sitting near the window with her medicine jar. She reached for his notes.
“Did it hurt?” she asked.
“Not sharply. It caught, then eased when I followed the full turn.”
“You stopped?”
“Yes.”
She read the marks along the edge of the diagram. “How many tries?”
“Two.”
“And you wrote down what happened?”
“I did.”
Ning handed it back. “Then keep the notes with the diagram. Don’t spend my medicine money on a manual yet. First find out whether this route is enough to keep practicing.”
“I won’t buy anything without asking.”
“I’m not asking you to ask me before every choice.” She returned her attention to the jar. “Just don’t use the money we set aside for my treatment.”
Yan sat beside her and checked the medicine label. It named the broth, the dose, and the days she should take it. “Did He say this is helping?”
“He says we’ll know after another week. I breathe easier when I’m away from Furnace Three.”
“Do you want me to ask Tao about a different shift?”
“I want to ask. You can come with me if you’re free.”
“I’ll come.”
Ning placed the jar beside the bill. “And if you find a better cultivation diagram, you can show me before you try it.”
“I can do that.”
“Good. Now eat. You look like you’ve been counting arrows all night.”
Yan took the bowl she had set aside. The broth was thin, but it was hot. He ate slowly while she folded the treatment bill and put it into a cloth pouch. Her plan remained expensive and uncertain. His own route had barely moved. Still, the diagram was no longer just a set of arrows, and Ning had a next question for the physician.
Before sleep, Yan copied the bend once more onto the inside of his work list. He placed the diagram beside the treatment bill on their shelf. Both plans were unfinished. Neither needed a grand promise tonight. At dawn, he would return to the yard, find the right count, and keep learning where the path went.
