Punk Hazard is the first island where straw hat pirates landed after entering the New World. A terrible accident happened, and a large number of corrosive substances were released from the island, resulting in the island becoming an uninhabited island. Two years ago, the Qing Dynasty and Chiyou fought a duel in Punk Hazard for the position of Admiral of the fleet (the duel lasted for ten days and ten nights, and Chiyou won in the end), which completely changed the climate on the island and turned it into an ice and fire island with half ice and half flame burning.
