In the wasteland city after the collapse of human civilization, Yan Zhao is the last unmodified natural human being, living on the edge of the data desert. When he was captured by the Eternal Life Group and forced to sign a consciousness uploading contract, Ji Lin, the former chief engineer who had personally designed the eternal life system, showed up as a traitor just to save him. The two confront each other in the gap between the neon debris and the brain-computer network. One wants to guard the end of human nature, and the other wants to sacrifice eternal life to rewrite the underlying code of the world. Seventy-two hours before the contract takes effect, they are no longer pursuers and prey, but the only companions who will face the end together.
