In the apocalypse after the nuclear explosion, humans have degenerated into lower species, and those with super powers are kings. Xiao Mo, an orphan who was abandoned by the laboratory, accidentally activated the ancient taboo [Demon Seed] in his body when he was selected as a sacrifice by the Guangming Cult. He discovered that he was the reincarnation of a fallen evil god and could devour other people's powers, memories and even destiny. He rescued Bai Ruoxi, a girl who claimed to be a daughter, but found out that she was the real culprit who caused him to be sacrificed - a fake daughter who assumed his identity and controlled the entire divine religion behind the scenes. Xiao Mo smiled sickly and decided to drag everyone into his game and let them taste the feeling of being sacrificed. He single-handedly slaughtered the branch temple of the divine sect, tracked Bai Ruoxi into the ruined city, and gradually discovered her connection with the mysterious organization Old Days Society, as well as a conspiracy related to the resurrection of the old gods.
