Three hundred years after the Tang Priest and his disciples succeeded in learning the scriptures, the earth shook, the devil suddenly fell, the Buddha died, and the three worlds were in chaos. Wu Tian occupied Lingshan, claiming to be "Wutian Buddha", and called all the demons to announce that Tathagata would be reincarnated with the help of Buddha body after 33 years.

Seize the nature of heaven and earth by seventeen relics, which is boundless in magic and belongs to the three realms. If you want to permanently occupy heaven and rule the world, you must use the Monkey King to gain seventeen relics and kill the reincarnated soul boy.

The Tang Priest, who is imprisoned in the underworld, knows well the lawless ambitions and plots that only Wukong can resolve. When Wukong learned about this, he immediately felt that things were not good. After burning the lamp to light the Buddha, he realized that the Three Realms were facing an unprecedented catastrophe.
