Ning woke before dawn coughing. The refinery vents had blown toward the labor quarter through most of the night. Each breath brought a dry rattle, then a pause in which she pressed her lips together and waited for the tightness to ease.
Yan pulled on his work shirt and reached for the cough tonic. “I’ll get the spoon.”
“I know where it is.” Ning took the bottle from the shelf and measured a dose herself. Her hand shook once when the cough returned. She waited until she could swallow, then drank the tonic in two small sips.
Yan sat on the stool beside the bed. “Does it help?”
“It soothes the scratch. The cough will take longer.”
He waited with her. The tonic had no cultivation herbs, and he had already tried a small sip. It had calmed his throat but changed neither his qi nor his channels. There was no reason to test it again. Ning’s breathing eased after a few minutes, though the cough did not disappear.
She capped the bottle. “You’ve been sorting your notes more carefully.”
“I’m trying to keep ordinary medicine separate from cultivation pills.”
“Because you think they change you in different ways?”
“Yes.”
Ning studied him. “You keep stopping before you say something.”
Yan looked at the notebook on the table. The split wrappers, receipts, and copied batch numbers lay beneath a clean cloth. He had kept the System to himself because he did not understand it. He had feared the same questions Zhao asked: what he had swallowed, when the change began, whether he had hidden a medicine. With Ning, the fear was different. He did not want to give her hope he could not fulfill.
“There is something I haven’t told you,” he said. “When I took the first draught, I saw a notice in my mind. It called itself the Bizarre System.”
Ning’s fingers tightened around the tonic bottle. “A notice?”
“It wasn’t a voice. It named what happened to the qi and the corrosion. The later pills gave short notices too. They kept the cultivation benefit and changed the cultivation-linked side effect.”
“Can it cure my lungs?”
“I don’t know everything it can do. I’ve seen it act on cultivation medicines. I haven’t seen it change ordinary tonic or heal an illness.”
Ning looked down at the bottle in her hands. “So you thought it might turn this cough into something useful.”
“I wondered. I took one sip before I understood the boundary. It only soothed my throat. I won’t test your medicine again.”
“Good. It’s for my cough.”
“I know.”
She put the tonic back on the treatment shelf. “I’m not angry you waited to tell me. I want to know if you’re frightened of it.”
Yan considered the question. “I’m cautious. I don’t know where it came from or what it can’t do. It hasn’t given me orders.”
“And you choose what to try?”
“Yes.”
“Then keep choosing carefully.” Ning shifted on the mattress and coughed once into her sleeve. The sound was weaker, but still rough. “Help me move the bed away from the draft. I don’t need you to find a pill for every bad night.”
They moved the bed to the wall nearest the inner courtyard. Ning wanted her books, water bowl, medicine, and spare clothes within reach. Yan tried to carry too much at once. A stack of folded cloth slid out of his arms and landed across the floor.
“Your new qi hasn’t taught you how many things fit in your hands,” Ning said.
“It’s a flaw in the training.”
“It’s a flaw in your planning.”
He crouched to gather the cloth. “I thought I could do it in one trip.”
“You can do it in three.”
They worked together. Ning carried the water bowl and her two smallest books while Yan moved the bed frame a handspan at a time. He stopped before the frame reached the wall, checked the floor for the loose board, then lifted his end while she pushed from the other side. The bed scraped, stopped at a seam in the stone, then moved free with a short groan.
“Wait,” Ning said. “That’s where the cold air comes through.”
She shifted the frame another foot, closer to the inner courtyard. Yan reset the blanket and lowered her medicine pouch onto the stool. Ning checked the tonic, her appointment slip, and the two fee receipts. Everything sat within reach.
The cough came again when a thin line of smoke drifted under the door. Yan opened it and looked toward the vent that fed the labor rooms. The draft had shifted. A ribbon of gray moved across the yard toward the outer wall.
“I’ll ask the vent attendant to note the hour,” he said.
“Ask if the wind changes on a schedule. Several people coughed last night.”
Yan went to the vent wheel. The attendant was tightening a chain beside the exhaust duct. Yan told him the smoke had turned toward the quarters before dawn and asked him to note the time on the shift board.
“I’ve had three complaints this week,” the attendant said. “I can mark the wind shift when I check the wheel.”
“Could the vent be turned away from the rooms?”
“Not without the supervisor’s order. But if I have the hours, I can show him the pattern.”
Yan thanked him and copied the time into Ning’s appointment note. He did not promise a change. A record of the wind was something she could bring to Physician He alongside the cough and the medicine bill.
When he returned, Ning had moved the books into a neat row. One cloth had fallen behind the bed. Yan reached for it, caught the edge with two fingers, and pulled it free.
“You don’t have to test your strength on every object,” she said.
“I was retrieving a cloth.”
“You were leaning as if you wanted the wall to challenge you.”
“I can be cautious and still reach.”
Ning smiled. “Then reach carefully.”
They finished the room together. She settled against the pillow in the new spot while Yan sat on the floor, writing in his notebook. The cultivation labels each named a qi benefit and an adverse effect. The cough tonic named no cultivation benefit. It soothed the throat and eased her breathing. Its bitterness was not a curse waiting to be reversed.
He wrote the tonic’s effect in a separate column, then added the time the smoke had shifted. Ning asked him to copy that last note onto her appointment slip. She would ask Physician He about the vent schedule and whether the cough needed a different treatment.
The cough returned once before midday. It was less frequent in the new spot, but it did not vanish. Ning took another measured spoonful of tonic, then rested with the window open toward the courtyard. Yan sat nearby and sorted the receipts from her medicine pouch, keeping the ordinary fees apart from the pill records.
He had learned where not to expect the System. It did not change every discomfort, and it did not turn an ordinary remedy into cultivation. Ning’s cough remained a cough. The tonic still helped in its plain way, and she had her own questions for the physician.
