I'm Calling a Red Alert in the Apocalypse

In modern society, a sudden global disaster strikes. It may be a mysterious virus brought by alien creatures, or an unknown scientific experiment goes out of control. In short, most humans quickly mutate into zombies. They have no reason and only know how to attack and bite all living creatures crazily. The whole world has fallen into chaos and darkness, cities have become ruins, and resources have become extremely scarce. The survivors are struggling to survive under the threat of zombies, and conflicts often break out between various small groups to compete for limited supplies. In such a desperate apocalyptic background, the protagonist unexpectedly embarks on a different path of survival.
