At 11:50 p.m., delivery rider Zhuo Xiaoman receives a strange order. The address is Old Locust Tree Alley, an area completely demolished three years ago. The recipient’s details are blurred, and there isn’t even a name.
Everyone else can see the eerie rules written across the ruins, but he can’t see a thing. Braised chicken deliveries, an abandoned school building, a sealed freight depot, an old restaurant buried underground… One after another, supernatural pocket dimensions that appear only late at night come looking for him.
His mother, missing for three years; a scar-faced rider trapped for a decade; a convenience-store girl with a secret; a stationmaster hiding his past: all of them are drawn into a cycle by a series of orders with no recipients. The source of the chain lies underground, endlessly swallowing anyone who strays inside.
Clutching the only copper key that can protect him from being assimilated, Zhuo Xiaoman follows the delivery route step by step toward the heart of the rules.
On this late-night food delivery, what is he really delivering: a meal, or his own life?
