After his soul crosses into the Journey to the West as an orange cat on Flower-Fruit Mountain, he activates the Achievement System. The first time he meets the unnamed Stone Monkey, he gives him the name Sun Wukong. He starts a school to teach physics, levers, and pulleys, builds an ironclad ship to accompany the monkey across the sea, and withstands Guanyin's schemes to capture the Third Prince of the West Sea alive. Through the Achievement Shop, he gradually unlocks the secrets of the Journey to the West and the chance to return across worlds.
