An opportunity that could have advanced humanity transformed into the ultimate weapon for its destruction due to an accident. Ordinary zombies with physical abilities on par with top-tier athletes, bizarre mutant zombies, mutant rats wreaking havoc underground, aggressive flocks of mutant birds attacking living beings in the skies, and deep-sea creatures that humans are utterly unprepared for have emerged. The arrival of these monsters has delivered a devastating blow to humanity, leading to the fall of major cities globally, one after another. To defend themselves, humans resorted to nuclear weapons, but this resulted in the emergence of even more formidable nuclear mutant zombies due to radiation. As the zombies continually evolve, humans are forced to retreat gradually, establishing gathering places where they do their utmost to defend against zombie assaults with whatever weapons they possess. Cai Wenjie, who had managed to survive for a decade in the post-apocalyptic world, ultimately met his demise at the hands of zombies. Perhaps God did not wish for the world to end in such a manner. The deceased Cai Wenjie returned to life, finding himself back three days prior to the apocalypse. He also acquired an arms system that enabled him to exchange points for various weapons to battle the unending horde of zombies. Decades later, confronted with a tsunami of zombies, Cai Wenjie coldly commanded, "Start the attack!" Following his directive, armored forces comprising countless tanks, armored vehicles, and mechas launched a counteroffensive against the zombies. The skies were filled with aerospace motherships, fighters, and bombers responding to Cai Wenjie's commands. Thus, the final confrontation between humans and zombies commenced.
