Gu took Yan to the restricted library after the morning shift. The transfer note from the catalog pointed to an east cabinet, its label faded until only a dark rectangle remained. A narrow brass plate showed the shelf number, but the ink beneath it had flaked away.
“Is this the military manual?” Yan asked.
“We’ll know when the catalog agrees with the cover.” Gu touched the cabinet door but did not open it. “Attendant Mo has the key and the sign-out book.”
Mo arrived carrying a ring of keys and a ledger. Gu showed him the transfer note. Mo checked the number twice, then found the matching entry in the book. “The manual was returned after inspection. It should be here, but the old tag is nearly gone.”
“Can we inspect it?” Gu asked.
“You may read it for one hour. Someone else has reserved the case this afternoon.” Mo opened the cabinet and took out a water-damaged book wrapped in waxed cloth. Gu signed the sign-out line; Mo recorded the time and handed over the key.
They carried the manual to a dry table. The cover was softened and stained, but the binding held. Gu opened it carefully and turned to the final section. The missing breath pattern from the red-wrapped Nine-Death fragment appeared there, though several lines had blurred where water had touched the page.
Yan held the corners flat without pressing the ink. “This is the same diagram.”
“The marks match the fragment.” Gu compared the two texts side by side. “The chest turn comes before the limb surge. The last breath carries the force outward.”
Yan followed the lines with his eyes. “The missing part tells the qi where to go after the rise.”
“Yes. A novice who sent the pressure straight through the ribs could injure himself before the intended burst.”
Gu checked the sequence against a second reference, a military index from the same collection. He did not treat the two records as equal instructions: one gave the pattern, the other confirmed its use and warning. He marked the matching points on a blank sheet, then asked Yan to explain the route without reading.
Yan began with the first breath. He named where the qi gathered, how it turned through the chest, and where the limbs received it. At the release, he pointed to the line that carried the force out and away from the ribs. He stopped before making the motion.
“What is missing?” Gu asked.
“Nothing in the complete sequence. The fragment is missing the final breath; this manual has it.”
“And what remains dangerous?”
“The art burns a month of lifespan and leaves an ordinary cultivator too weak to stand. A failed route can stop the heart. The warning describes other bodies accurately, even if my response may differ.”
Gu nodded. “That is the difference between understanding a text and deciding to activate it.”
Attendant Mo returned to the table. “Your hour is nearly over. Another researcher has reserved this case.”
“Could we have one extra hour?” Gu asked. “The catalog tag has faded. I can repair it before we return the book.”
Mo looked at the broken label. “If you repair it, I’ll extend the sign-out. The book stays here, and no page leaves the room.”
“Agreed.” Gu brought out a fresh tag, paste, and a small brush. Yan held the manual open while Gu copied the catalog number, source, and damage notice. They worked quickly but did not hurry over the fragile pages. Mo read the entry aloud before Gu attached it to the case.
Mo compared the repaired tag to the old catalog number. “This book has been on the wrong shelf twice. One move was written in ink and one in pencil. That is how the transfer number got hard to read.”
“Was it missing long?” Yan asked.
“Long enough for someone to stop asking where it went.” Mo pressed the tag flat. “The case itself never left the library. It was mislabeled, not lost.”
Gu checked the tag’s edge and added a small protective strip. “Now the next reader won’t have to guess.”
Mo inspected the book’s water damage and had Yan hold the cover while she checked the lower hinge of the case. “Keep the pages flat, and don’t use a wet brush near the ink. We’ll let the cover dry before the next inspection.”
Yan adjusted his grip. The softened board flexed slightly, but the spine held. “I’ll support it here.”
“Good. A damaged book can survive a careful reader. It cannot survive a careless repair.” Mo returned the key to Gu and stamped the extended sign-out time. The extra hour was now properly recorded.
“The library has a talent for making dangerous arts harder to find than taxes,” Yan said.
“Taxes have better labels,” Mo replied.
The three of them laughed. The repair bought them time to compare the last breath, but the manual had to go back before evening. Yan copied the sequence once into his notebook, with the lifespan warning on the same page and the source number beside it. He did not remove the text or omit the risk.
Before they returned the case, Gu made him recite the opening and final breath together. Yan described the full method and then performed the motions without qi. His shoulders turned, his chest opened, and his hands traced the release point. No qi gathered. No silent notice appeared.
Mo checked the book back into its case. He stamped the return slip and asked Gu to keep the pages flat overnight. Yan folded his copy into his inner pocket, leaving the warning visible at the top.
“I’m excited to practice it,” Yan said as they left.
“Excitement doesn’t replace a second reference.”
“It doesn’t. We have the method, the index, the warning, and an empty courtyard.”
“And a teacher who will review your count.”
Gu agreed to supervise a low-output practice at dawn. They would mark a chalk boundary to keep the burst away from the storage wall. Yan would gather only enough qi for one careful circulation and stop if the route broke or an outside injury interrupted it.
The manual remained locked in the restricted case. The source tag was repaired and the complete breath pattern now had a reference. Yan felt eager to begin, but the hour had ended. He returned to the yard with the copy in his pocket and waited for the next day’s supervised practice.
Outside the restricted room, Gu checked that the notebook page had not been folded across the warning. “Your copy cannot replace the book. If another researcher checks it, they need to see the source and the damaged line.”
“I can show the catalog number and the index page.”
“And tell them which part came from which reference.”
Yan turned the page in his notebook. He had written the manuscript number next to the sequence and the military index number beside the arrow. “I did that.”
Gu read the copy and nodded. “Then tomorrow we can use the complete route. Today you have a clear transcription, not an activated art.”
Yan put the notebook back into his inner pocket. He did not feel the force of the method in his body; only the ordinary warmth of the morning sun reached his sleeves. The technique was still a set of instructions on paper.
