In the near future of 2080, in an era of highly developed science and technology but acute social conflicts, breakthroughs in quantum computing and biotechnology have brought about changes in social structure. The story begins with the vertical urban structure of the "dome area" and "underground city" in New Shanghai, and later expanded to many distinctive future cities around the world. The world has been changed by the black market of "memory trading". Human beings can sell/purchase memories through brain-computer interfaces, leading to identity crisis and social unrest. Seven major technology groups control the core technology of memory editing.
