The protagonist shares a name with the Great Sage. He was supposed to die, but because he carried the Great Sage’s aura, the underworld’s soul hunters mistook him for the Great Sage. Through a series of accidents, he inherited a strand of Sun Wukong’s “monkey aura” and gained extraordinary abilities. To change his own fate and save the Great Sage, who is in danger because his “monkey aura” is draining away, the protagonist is forced into the conflicts of the Three Realms. He must deal with the underworld’s efforts to hold him accountable and correct its mistake, face the monsters and demons coveting the “monkey aura,” and, with the pilgrimage party’s covert help, find a way to restore the Great Sage’s divine power and uncover the conspiracy behind the mistaken entry in the Book of Life and Death.
The story revolves around “redemption” and “growth.” From his initial struggle to survive, the protagonist gradually learns the responsibility and courage carried by the “monkey aura” as he navigates the powers of the Three Realms and faces trials in vanquishing demons. In the end, he not only succeeds in saving the Great Sage, but also uncovers the deeper secrets of the power struggle between the Heavenly Court and the underworld. He transforms himself and becomes a unique guardian connecting the mortal world and the Three Realms.
