Earth's civilization collapsed instantly with an inexplicable "big bang", and the survivors struggled to survive among the devastated ruins. Zhao Tianqi and others struggled to survive under conditions of ridicule, chaos, and absurdity, encountered good and evil by chance, intertwined their fates, and embarked on a journey to find "the wreckage of meaning." They formed a temporary alliance, but also experienced internal fighting. They experienced absurd trials, siege by nonsensical monsters, fantasy order construction, large-scale psychological invasion, etc., And finally gave a new definition to a new society and self-destiny in the "human ruins" where despair and hope intersect. Absurdity and tenderness, hope and confusion, animality and divinity are presented in the quarrels and coexistence of the survivors. At the end, the group reaches a fragile harmony in conflict and cooperation, sacrifice and choice, and the fire of civilization is rekindled in a grand "Doomsday Carnival".
