Under the Lingshan Mountain, Zhu Bajie, the envoy of the Pure Altar, indulges in endless worship and enjoyment. No one knows that under this greedy and lazy skin, five hundred years of undying hatred and shocking secrets are buried. The battle between the real and fake Monkey King was not a false alarm, but a killing plot carefully laid out by the Tathagata - the real Sun Wukong had long since fallen, those on the westward journey were just Buddhist puppets, Tang Monk was reincarnated and imprisoned, Sha Monk was sealed by the Buddha's throne, and everyone who had studied scriptures in the past became victims of the power struggle between heaven and Buddhism. Only Bajie understands everything and endures for five hundred years, just waiting for the day of revenge. When he finally broke free from the shackles of Buddhism, shed his disguise as the messenger of the Pure Altar, revealed his true nature as a wild boar, and took out the three life-saving hairs entrusted to him by Brother Monkey, his obsession with resurrecting the Great Sage ignited a prairie fire. From then on, Bajie left Lingshan alone and embarked on the road against heaven. He will travel through the three realms and gather together Yang Jian, Nezha, the Bull Demon King and other immortals and demons who are dissatisfied with the power of the Buddhist court. Using his hair as a guide, he will resurrect the Monkey King against the heavens and set off an unprecedented war against Buddhism and heaven, allowing the gods and Buddhas to repay the blood debt of five hundred years.
