During summer vacation, Fan Kun is working a part-time job when he is supposed to be transported with all of humanity to the land of the apocalypse three days later. Unexpectedly, he arrives ahead of schedule. He chooses a god-tier cave with the ability to "devour," allowing him to seize the attributes and resources of other shelters. In a region inhabited by beastfolk, he disguises himself as a royal nine-tailed celestial fox. While hunting the rotting corpses to increase his cultivation and stockpile spirit crystals, he builds a faction called the Heavenly Palace and recruits subordinates. Surrounded by both the rotting-corpse calamity and the beastfolk, he grows stronger step by step and faces cross-region competitions, carving out a path to survival for humanity in the apocalypse.
