In a world where the Demon Kings have destroyed human civilization, awakened human fighter Si Chen loses everything and, in despair, chooses a final “one-for-one”—he self-destructs and manages to take down one Demon King, the Glutton 婪月, with him. However, when he opens his eyes again, he finds himself ten years in the past, before the catastrophe and before the Demon Kings’ invasion has begun. Realizing he has awakened his powers early in this second chance at life, Si Chen decides to act in advance: prepare humanity, hunt threats ahead of schedule, and change key events to prevent the previous tragedy. As he moves, the original “script” of the world begins to shift—fates, timelines, and power balances all start to distort around his reborn presence.
