When a solar storm tore through the earth's ionosphere, Lin Ye, who had been reborn 49 times, finally activated the apocalyptic survival system. Infinite storage space is bound to an abandoned gas station, and the mecha with neural connections is armed to the teeth. However, this reincarnation has a fatal twist - an AI girl who claims to be his creation in the 49th life breaks into the safe house with a warning about the paradox of time and space. Faced with the early arrival of the mutant beast tide and the chaotic timeline, 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 in his first reincarnation. When the mecha's shock blade cut off the bone armor of the Earth Devouring Beast, he discovered that he was hoarding not only supplies, but also causal weapons accumulated through 49 reincarnations.
