Young Sun Jian accidentally stumbles into the world of Journey to the West. After discovering that he has taken possession of Sun Wukong’s body, he has no choice but to bear the fated task of accompanying Tang Sanzang on his journey to the Western Heaven to obtain the scriptures. Tang Sanzang may seem selfish and scheming, but when life and death are at stake, he can still stand firmly for what is right. Greed possesses Zhu Bajie, whose ravenous, murderous nature must be restrained by the tightening spell, yet he remains infatuated with Chang’e. Sha Seng may seem dull-witted, but he has secretly pledged himself to the demon realm. Sun Jian has the body of the Great Sage Equal to Heaven, but after losing all his demonic power, he starts out as one of the weakest fighters around. They journey west, growing stronger along the way. After the four of them become gods, they each lose their restraints. Then the supreme ruler of the demon realm, sealed inside the Golden Cudgel, uses Sha Seng to break the seal and gathers the demons to launch an assault on the Celestial Realm. The Buddha is defeated, the Heavenly Court falls, and Flower-Fruit Mountain becomes the gods’ final stronghold. Amid the calamity engulfing the three realms of demons, devils, gods, and humans, Sun Jian turns the tide, transcends the limits of his race, and becomes the Great Sage Equal to Heaven who unifies the three realms!
