The story of the game takes place after the completion of the Journey to the West, where Sun Wukong abandons his Buddhist throne and returns to seclusion on Mount Huaguo. However, the Heavenly Court believed that he was still an "unstable factor" and sent Erlang Xiansheng Zhenjun to suppress him. In the end, Sun Wukong died in the battle with Zhenjun, and his five roots were divided among the five demon kings, while "Yi" turned into a strange stone, becoming a legend passed down orally by monkeys and grandchildren.
