X years later, an unknown biochemical disaster broke out. Zombies, monsters, and natural anomalies made the world a mess. Li Qingning leads a team with different personalities to find a way out of a ruined city: they fight side by side against mutated creatures, ruthless survivors, resource crises, and the team makes fun of themselves. Crisis came one after another, and conflicts arose inside and outside the team. They complained and grew up along the way, completing their understanding of their homeland and their mission. Different stages have their own ultimate goals: first to escape from the city (Volume 1), then to find material bases and survivors (Volume 2), to overcome internal and external troubles and the test of human nature (Volume 3). In the final volume, under the great changes in Wang Qiming's organization, they work together to resolve the final crisis of the apocalypse, and usher in the rebirth of the world with laughter. The whole book uses humor to smooth out the scary atmosphere, but the pace is tight and the climax is ups and downs. The absurdity of the doomsday is full of human warmth and warmth.
