In Xinhai City, a giant city built with "consciousness uploading" technology, classes are strung out like a chasm. "People in the clouds" enjoy eternal life in the virtual heaven "oracle", while "people on the surface" struggle to survive in the cold real world. Lin Che, a low-level prosthetic repairman, is constantly running for the sake of his seriously ill sister. In an accident, he touches the "fragment of consciousness" hidden deep in the late giant, and gets a glimpse of the shocking secret that may be hidden behind the immortality of the "oracle". For the sake of his sister and the truth, he will fight with his small body against the behemoth - Tianqiong Group. When the weak fight back, when the false immortality is torn apart, where will the fate of Xinhai City go? A cyberpunk epic about survival and resistance, reality and illusion, is about to begin.
