Weird Invasion, I Am a City Maintenance Worker

At 2:17 in the morning, night shift maintenance worker Gu Yan received an elevator repair order from the thirteenth floor of the hospital. But this building only has twelve floors. Outside the elevator door is an inverted corridor, and a caregiver is being swallowed by the wall. After rescuing people, Gu Yan found the work badge of his father who died three years ago at the bottom of a well. There was only one sentence on it: Node 13, repair prohibited. From that night on, Gu Yan could see the city's abnormal "fault points" and the only shortest repair path. A collapsed hospital, a subway that runs backwards, a streetlight that traps people at the same time... He knows where to start, but he may not be able to afford the cost of repairing it. Because every time a malfunction is repaired, the damage will be transferred to him: hypothermia, deafness, and even the loss of a memory. All faults point to the thirteen blocked nodes left by his father. When the fourteenth fault lit up in the rehabilitation center where his sister was located, Gu Yan finally understood: the city was not broken, it was looking for new "maintenance workers."
