The register chose him. The night shift will never be the same.

Lin Chuan is 24, broke, and working nights alone at a Linhai convenience store to pay off his father's medical debt. Then, at 2:00 a.m., a customer with antlers pays for batteries with a coin that isn't money — and a System wakes up in Lin Chuan's head.

[QUEST: The store must never close. No customer leaves unserved.]

After 2 a.m., Linhai has a second economy: fox-fairies in delivery jackets, hungry ghosts, minor river gods — and they all shop at convenience stores. Every customer served earns Night Coins. Coins upgrade the store. And an upgraded store is a sanctuary — which makes it a target for the Hollow Merchant, the thing quietly buying up every place in the city where people wait.

His cheat isn't strength. It's retail.

Night Shift System is the first book of the Lantern Street series — an urban fantasy LitRPG with a consistent, auditable System, a night-city China setting, and a hero whose superpower is customer service.
