Delivery boy Lin Mo accidentally awakens the power of time retrieval when he breaks into a fight between people with supernatural powers on a rainy night. The dark pattern that appeared on his left hand, the flashing memory fragments of the laboratory, and the "seventh-generation container" gene lurking in his body dragged him into a dark war that had been hidden for thousands of years. When he rescued the amnesiac girl Bai Li who carried the genetic key, dormant forces from all sides suddenly awakened - the "Night Watch" in the name of order, the "Eclipse" who carried out the human cleansing plan, and the "Rebirth Society" who indulged in supernatural powers and pleasure, all wanted to turn his power of time and space into authority.
When superpowers around the world went berserk due to the genetic key, and the door to the abyss of sin in ancient ruins opened, Lin Mo had to struggle with the darkest choice: Should he erase all human superpower genes and return to ordinary life, or should he, as the gatekeeper of time and space, bet on an unknown new world in the countdown to doomsday?
