A global catastrophe caused by a mysterious virus has destroyed modern civilization. In their journey of survival where humor and madness coexist, Mo Xiaoye and his "Wasteland Happy Team" constantly encounter absurd dangers, tests of human nature, power struggles, and intertwining love and hate. The three volumes respectively tell the story of team formation and survival, the fierce conflict between power and conspiracy, as well as the revelation of the truth and the ultimate choice. During this period, multiple story lines are intertwined and advanced, each protagonist has unique growth, and the endings of each volume are closely linked. In the end, they "laughed into the doomsday" with an optimistic attitude and used each other's lives to write the last hope of the doomsday.
