Because the protagonist has the same name as the Great Sage, he was originally the one to die. However, his body was contaminated by the Great Sage's aura, and he became the Great Sage through the seduction of the underworld. However, by accident, he inherited a ray of "monkey energy" from Sun Wukong and gained extraordinary abilities. In order to reverse his own destiny, and to rescue the Great Sage who was in danger due to the loss of "monkey energy", the protagonist is forced to be involved in the dispute between the three realms: on one hand, he has to deal with the accountability and correction mechanism of the underworld, and on the other hand, he has to face the demons and ghosts who covet the "monkey energy". With the secret assistance of the scripture collection team, he must find a way to restore the power of the Great Sage and uncover the conspiracy behind the wrong connections in the Book of Life and Death.
The story revolves around "redemption" and "growth". From the initial passive survival, the protagonist gradually understands the responsibility and courage carried by "monkey energy" through the experience of dealing with the forces of the three realms and conquering demons. In the end, he not only successfully rescues the great sage, but also reveals the deep secrets involving the power game between heaven and earth, completes his self-transformation, and becomes a special guardian connecting the human world and the three realms.
