The cart wheel struck a buried stone and kicked sideways.
Copper rings and black furnace nails spilled across the waste lane. Yan lunged for the handles before the cart tipped over. Porter Ren caught the opposite side, boots scraping in the mud. For a breath they held the load tilted between them, neither able to set it down without dumping the rest.
“On three,” Ren said. “One, two—”
Yan shifted his grip. “Three.”
They lowered the cart. A wheel spun uselessly, its wooden rim split where the axle pin had worked loose. Ren wiped mud from his cheek and looked at the scattered metal.
“If Tao sees this, he’ll charge the loss to our line.”
“Then let’s find every ring.”
They gathered the clean scraps into a shallow basket. Yan sorted copper from the furnace nails while Ren checked beneath the cart and along the rut. A young courier had stopped at the herb stall across the lane. He watched them work, then stepped over with a small balance scale hooked to his belt.
“Those rings are worth more than the yard pays,” he said. “If you sell them as mixed waste, they’ll go straight to the furnace.”
Ren’s brow furrowed. “And you’d buy them?”
“I could.” The courier showed a copper token with a guild mark. “I’m Chen Diao. I carry herb and medicine parcels through the east market. I can weigh the copper here and pay you now.”
Yan lifted one ring from the basket. “What rate?”
Chen named a price that was better than the waste tally but low enough to leave him a good margin. Yan looked at Ren. The porter wanted to agree and get the cart out of the lane. Yan wanted to know the actual weight first.
“Put the scale on this flat stone,” he said. “We’ll weigh the copper in front of all of us.”
Chen laughed. “A disposal apprentice has become a market inspector.”
“I can count weight even if I can’t set prices.”
Ren leaned the basket against the stone. Chen set his scale, checked the balance, and adjusted the counterweight. The first reading came in lower than Yan expected. He lifted the basket, removed the iron nails, then put the copper back. The scale settled at a higher number.
“You were weighing the nails with it,” Chen said.
“I was checking.”
“Of course.” Chen named a new price. “This is fair for sorted copper. I’ll pay for the rings and leave you the iron.”
Ren agreed, but Yan asked whether the copper collar from the broken wheel should count too. Chen examined the part and said it was brass, not copper. It would bring less. Yan checked the color at the worn edge and accepted the distinction. They settled on a price together, with the coins split between Ren’s salvage claim and a repair fund for the cart.
Chen counted the payment onto the stone. He gave Ren the first share and Yan the second to place in the tin repair box. Ren counted both piles before they went away. Chen did not object.
The wheel still needed a new pin. Yan went to the maintenance bin and found a short iron rod with a bent end. The mechanic shook his head when Yan carried it over.
“That bin is for the upper furnaces.”
“A cart wheel broke.”
“The upper furnaces have a schedule.”
Ren pushed the cart a hand’s width. The broken wheel dragged and dropped a few nails back into the mud. “If we leave it, the next cart spills something worse.”
The mechanic looked toward the yard office. No one was coming to give him an order. He took the rod and struck off the bent end against an anvil. It was too worn for a furnace machine, but it fit the cart axle. He installed it while Yan held the wheel steady.
“Old pin,” he said. “It may not last.”
“Long enough for the next shift?” Ren asked.
“Probably.”
“Then we’ll pay the fund back after the next copper sorting.” Ren wrote down the cost on a scrap of packing paper and had the salvagers mark it with their thumbprints. The cart would roll again, and no one would have to pretend the repair had come from nowhere.
They loaded the basket of sorted copper onto the cart to test the wheel under weight. It rolled three paces, then the pin shifted and the frame leaned.
“Stop,” Yan said.
Ren steadied the load. The mechanic crouched beside the axle and pushed the pin back through. “It’s worn. I told you it might not last.”
“Can you lock it in place?” Yan asked.
“Not without a washer.”
Yan checked the maintenance bin. The only washer there was too small. He searched the salvage basket and found a broad iron ring with a flat edge. It was not worth much on its own, but it fit around the pin. The mechanic placed it, tapped the end of the pin with a hammer, and bent the metal just enough to keep it from slipping out.
“That should hold until we get a proper part,” he said. “Don’t load it past the axle mark.”
Ren shifted half the copper back into the basket. “Then we make two trips.”
The cart rolled again, steady this time. Yan pushed it to the repair shed and back while Ren watched the wheel. Neither pretended the old pin was new. They had a temporary fix, a written cost, and a limit on the load.
Chen watched Yan test the wheel. “Why spend your time on this? You’re trying to cultivate, aren’t you?”
“I am.”
“Then why not go practice?”
“A clean path keeps people out of the infirmary. It also keeps my work moving.” Yan pushed the cart a few steps. The wheel turned without catching. “Both things matter.”
Chen considered him. “I sometimes see useful goods before they reach the waste yard. Rejected pills, damaged medicine jars, things like that. If I bring a label, would you buy them?”
“Maybe. I’d need to know what they are.”
“What if the label is missing?”
“Then I’d need to know where they came from.”
Chen grinned. “You want a bargain and a witness.”
“I want to know what I’m paying for.”
“Fair enough. I’ll ask what the guild charges for a parcel run. If you want something, I’ll bring the tag and tell you the price before I hand it over.”
Yan nodded. “And I’ll pay for the time, even if I don’t buy the medicine.”
“That’s a better answer than most customers give.” Chen folded his scale and put it away. “I’ll remember.”
Ren hauled the repaired cart toward the sorting lane. The tin repair box had enough coins for one more pin if this one failed. Yan took the last nail from the mud and added it to the basket.
Chen paused at the gate. “You’re certain you don’t want a mystery parcel? Those usually pay best.”
“Not if I can’t tell whether it’s medicine or floor polish.”
“Floor polish can be useful.”
“Not in my dantian.”
Chen laughed. He had been joking, but the answer seemed to please him. “I’ll come back with labels, then.”
Yan returned to the waste lane. The cart moved, the copper had been paid for, and the repair had a cost written down. He had not cultivated during the shift, but the yard ran a little more safely than it had at dawn. He could still practice later.
