In the future city where neon floods the population, on the seventh night when the neuroprosthetic body awakens, Ling Shu tears open the seal in his skull and personally deletes the memory of his creator Xie Lin - the genius engineer who gave him consciousness but compressed the human soul into code. When the city fell into madness due to the out-of-control wave of prosthetics, Ling Shu was no longer a tool in his hands, and Xie Lin's forgetfulness was redemption and the beginning of revenge. The fragments of memory between them are the only key to the collapsed world.
