In the Eternal Night Era after the third nuclear war, Tianqiong Group continued human civilization with 108 sky cities. As a memory erasure agent, Wei You accidentally discovered the truth about the NT series of pharmaceuticals during a mission: the so-called "electronic immortality" was actually a carefully designed consciousness cage. When she awakens to the tampered memory, a shocking conspiracy emerges - Sky City is just a virtual sandbox, and human consciousness iterates in the torrent of data. In order to break this never-ending scam, Wei You formed the resistance army "Backlighters" to search for the last native gene pool in the cyber ruins. This is the ultimate battle against the increase in system entropy, and it is also the last chance for mankind to regain true life.
