The whole process of the protagonist from being expelled from Buddhism to finally promoting the transformation of the Three Realms. It includes the development of the relationship with Sun Wukong, who is both a teacher and a friend, an in-depth debate with Tang Monk about Buddhism and reform, a conceptual confrontation and final showdown with the devil Wu Tian, a game with the Jade Emperor in heaven, and a system test promoted in the human world. Finally, a new order was established in which "the law of heaven is public, gods have responsibilities, and mortals have rights."
