Wang Yuan was originally an ordinary college student. By some mistake, he traveled to the earth hundreds of years later. The earth is on the verge of extinction because of human overexploitation. But humans still go their own way, which may annoy the earth.
The water quality of the earth has changed, starting from European countries and spreading to the entire earth. Not only humans have mutated into the species in the movie that loves to eat creatures and has no sense. Even animals began to mutate. Humans are called zombies. At first, the country did not pay attention to it. Just send troops to hunt mutant species.
Gradually, things improved. Humanity returned to its former greedy state, but a zombie wave occurred. No one knows what's going on, maybe it's because of human beings' impenitence. All in all, most humans died in this tide of corpses. The government immediately sent troops to control the situation. But he found that ordinary weapons could not hurt him at all, because humans underestimated the enemy. Most of the human race died again.
Humanity finally began to panic and repent. The Earth probably didn't want the child he had cared for for thousands of years to die like this. So one after another, superpowers appeared. They fought off the zombies for the time being.
The superpowers got together and established two bases, one was the Al base and the other was the AX base, which were established by Qiao Yisui and Xiao Ji respectively.
