The virus broke out and the world turned into a barren wasteland. Five ordinary people with different personalities formed a doomsday survival team by mistake, and forged ahead in the wilderness of laughter and tears. From robbing supermarkets, building armored vehicles, and making jokes with each other, to fighting mutant monsters, extreme weather, and mysterious organizations, the story progresses in many ways. The main plot is the exploration of the origin of the unknown virus, while the subplot shows the emotional bonds, growth and transformation of the team members. Each volume has a main line, which is advanced layer by layer, and at the end it directly touches on the truth and human choice.
