Before the End, I Received Tomorrow's Scraps

In 2042, Cheng Ye, the director of the old resource recycling station, would receive a piece of waste from the accident 24 hours later at 0:17 every day: a broken door lock, a burnt gas valve, and an emergency light stained with white glass powder. There are no instructions, just the injury itself. In order to save the people of tomorrow, he must read the disasters that have not happened yet from the wreckage, but gradually discovers that these accidents are not accidents, but "sacrificial costs" actively calculated by a set of urban algorithms. When the "white tide" of extreme rainstorms approaches, the entire city only has twelve days left. He could fix a machine, but he had to learn to work with ordinary people to fix a city that judged them as of low value.
