A Delivery Guy Becomes a Rules Repairman

On a late-night delivery run to Room 404, Lin Du crashes headfirst into Building Three of Xingfuli, a place that doesn’t exist on any map.

Contradictory tenant rules, an endlessly looping fourth floor, living people whose traces vanish in the blink of an eye… Rule-based horrors sweep through the city overnight. One wrong step, and you disappear from the world for good.

The mysterious markings left behind three years ago awaken: a restorer’s vision. While others follow the rules to their deaths, he exploits their bugs, dismantles endless loops at the code level, and contains one out-of-control anomaly after another.

From a single safe house to a sanctuary for the entire city, he brings back the people whose names were erased and builds the last bastion of order in the apocalypse.

Across countless cycles of the eras, the Zero Repairer, who looks exactly like him, has been waiting for him again and again.
