In the tenth year of the endtimes, human civilization collapsed, with only a few surviving super main cities building walls to defend themselves amid the gaps of zombie hordes. Survivor Li Xingyue gained total immunity to the zombie virus due to his unique physique. In the dead city of Xinghai City, by a twist of fate he came to know the four eighth-tier corpse kings (Tyrant, Asura, Nun, and Blood Moon) who had already birthed independent spiritual intelligence, and became sworn brothers with them amidst comical interactions. To explore the truth of the endtimes and the survival rules of human society, Li Xingyue disguised his identity and headed to "Free City", starting from the bottom corpse-hunting team assessment, making companions, forming a squad, and shuttling between dangerous ruins to hunt and rank up.
