In the silent ashes of the city, Yan Shu is a numbered "repairer" who repeatedly repairs broken memory fragments for the system every day. There are no stars in his world, only endless surveillance and tampered truth. By chance, he captured a "hope for the future" in the data afterimage, a revolutionary fire that had been completely erased. Yan Shu couldn't let go, and the glimmer of light ignited fanaticism in his heart. He secretly contacted the "scavengers" scattered in the shadow of the city. Between chasing the truth and escaping to death, Yan Shu worked step by step, vowing to piece together a complete picture of hope. But the real enemy is not the high wall and the iron curtain, but the "memory self-destruct command" implanted by the system that may explode at any time. In this competition between memory and will, how can Yan Shu protect humanity in forgetfulness? When hope becomes the most dangerous taboo, can he reverse his destiny and bring light back to a dark world?
