In the fifth year of the apocalypse, Zhou Meng is betrayed by his most trusted brother and the woman he loves, who together shove him into a horde of zombies. Only as he dies does he learn that he has been nothing but a pawn from the very beginning. Consumed by rage, he hears a mechanical voice just as his consciousness fades: "Extreme will to survive detected. Binding System... Binding failed. Host's vital signs have ceased. Initiating temporal rewind program..."
When he opens his eyes again, Zhou Meng finds himself lying on the bed in his rented apartment. His phone screen shows that the apocalypse will begin in one hour! Given a second chance, he is no longer the naive, trusting ordinary man he used to be. A mysterious entity called the "Infinite Growth System" merges with him. From then on, killing zombies makes him stronger, completing missions earns rewards, and he gets to choose his own path of evolution.
Reborn, Zhou Meng has clear goals: First, survive. Second, find Su Qing, the doctor who saved him in his previous life, and repay his debt to her. Third, make that pair of wretches taste utter despair. But when he uses his memories to track down Su Qing, he discovers that the calm, astute doctor seems to be hiding a secret of her own. Meanwhile, the traitors from his previous life have joined forces ahead of time and are waiting for him to walk right into their trap.
This is a race against time, and a battle against human nature. As the city's order collapses and zombies howl across the skies, Zhou Meng carves out a path to survival through mountains of corpses, armed with the System and his memories of his previous life. He will build his own power amid the ruins and uncover the shocking conspiracy behind the apocalypse. He will face powerful figures who are neither wholly good nor evil, and with each choice, redefine the boundaries between trust and betrayal, humanity and survival.
