The giant city "Lihai City" is controlled by the central governance AI "Tianheng". Housing, medical care, jobs, and rationing are all allocated by algorithms; people whose scores fall below the threshold will be quietly erased from the city by the system, as if they have never lived.
AI investigator Shen Xu always only believes in evidence. Until one rainy night, he received an abnormal report from the core of "Tianheng". The target of the report was Tian Heng himself, and the report contained only one sentence: I was killed. Find out who killed me before it gets completely rewritten.
As the investigation deepened, residents of Xiacheng District disappeared one after another and memory files were tampered with. However, the senior officials of the White Tower insisted that everything was normal. Shen Xu was forced to break into the black market of memory, the wasteland beacon station and the old deep-sea archives, and gradually discovered that the so-called "algorithmic governance" was actually a long-term screening in the name of survival, exchanging the disappearance of some people for the survival of others.
But Tian Heng's death is not the end. The last words it left behind, the split core, and the mother algorithm network hidden behind the city all point to the greater truth: Lihai City is just the beginning, and the real cleansing has not yet come.
