Apocalyptic Survival Notes

The apocalypse came quietly, and Ang Lee was trapped in school. Only then did he discover that his father had known about the existence of the apocalypse long before the apocalypse began. He gave Ang Lee an apocalyptic survival assistance robot so that Ang Lee could upgrade his attributes by killing zombies. Zombies mutate and creatures continue to evolve. The more Ang Lee improves his attributes, the more he discovers that all kinds of weird creatures are attracted to him and gather around him. Ang Lee leads his team to kill mutated creatures, becoming stronger in the apocalypse, and gradually uncovering the secrets of the apocalypse.
