When Qiao Wan steals Li Zhao’s identity, she thinks she is simply reclaiming her right to survive. What she doesn’t know is that Li Zhao’s body contains the ‘doomsday key’ that can restart civilization, and that she is gradually being consumed by the other half of the key’s consciousness. Qin Shang manipulates events from the shadows; Bai Rui alters memories; Shi Jin guards a forbidden password; and Su Ling bears the name of a sinner. The four fit together like interlocking gears, setting in motion a civilization’s reboot that no one knows is coming. When two souls confront each other in the abyss of consciousness, what the key truly opens is not the future, but a past humanity has never dared to face.
