Terminally ill youth Li Xingyue wakes up to find himself in Xinghai City, ten years into the apocalypse. Naturally immune to the zombie virus, by a twist of fate he swears brotherhood with four eighth-rank zombie kings, including a tyrant and a nun! Entrusted with an undercover mission by the zombie kings, Li Xingyue infiltrates Freedom City, a human survivor base. Inside the city, human hearts are treacherous, the zombie-hunting trials are perilous, and the adjudicators are mercenary. Possessing zero combat power himself, he recruits partners to build a team. Watch as he relies on extraordinary intellect, backed by a group of max-level zombie king brothers secretly escorting him, playing the pig to eat the tiger, and maneuvering between the human and zombie factions!
