In 2025, a quantum-collapse disaster strikes, causing reality to overlap with parallel universes. Every 10 days, the “Doomsday Countdown” begins. Ordinary college student Lu Chen awakens the Doomsday Simulation System, which lets him spend his lifespan to enter a simulation space and prepare for crises. But each simulation splits off countless versions of himself, and only Lu Chen, who devours the others from different universes, can survive. The price: for every day he “lives,” his lifespan in reality shrinks by 100 days.
