When a solar storm tears through Earth’s ionosphere, Lin Ye, reborn for the 49th time, finally activates the Apocalypse Survival System. An abandoned gas station is bound to an infinite storage space, and his neural-linked mech is armed to the teeth. But this time, the cycle has a deadly variable: an AI girl who claims to be his creation from his 49th life, carrying a warning about a spacetime paradox, breaks into the safehouse. With the mutated beast tide arriving ahead of schedule and the timeline in disarray, Lin Ye must complete three impossible tasks before the countdown reaches zero: destroy the antimatter signal tower, recover the star core fragments, and kill himself from his first cycle. When the mech’s vibrating blade cleaves through the bone armor of a Devourer, he realizes he hasn’t just been stockpiling supplies, but weapons of causality forged over 49 cycles.
