In the Taoist Cave of Qingxuan Mountain, the senior brother Gu Cangyan, who was transformed from the Chaos Qingling, has followed Taoist Xuanqing since he was a child, teaching on his behalf, and has seen the ups and downs of the three realms. One day, a stone monkey with clear eyes became his apprentice and became his most beloved junior disciple. The stone monkey is extremely talented and only seeks immortality, but in the chess game of cause and effect set up by the immortals and Buddhas, he goes from the stubborn monkey seeking immortality to the Holy Lord Tongtian who makes trouble in the heavens, to the demon-conquering Arhat who travels west to obtain Buddhist scriptures. He finally sees through the hypocrisy of the gods and Buddhas and rebels against heaven.
