Journey to the West ended five hundred years ago, and Hunyuan restarted five hundred years later. When Xuanzang passed away mysteriously, he discovered that the faded brocade cassock actually concealed the totem of the Setting Moon and Three Stars Cave. When the Buddha's light turns black and the moonlight flows backwards, the truth behind the sutra becomes a sharp blade that pierces the three realms - the inscription on the golden cudgel is the stanza of Bodhi's enlightenment, the Sanskrit inscription on the tight hoop is the key to the Hunyuan calamity, and the spiritual stone monkey bred by the Sky-Mending Stone is actually the half of the Taoist body chopped off by the ancient saint.
In order to find out the mystery of the disappearance of his mentor Bodhi, Wukong breaks through the rift in time and space and faces the thousand-year bet between Tathagata and Bodhi. The secret realm of Sanxing Cave hides loopholes in the way of heaven, and the wordless scripture contains the manual of the God-killing Sword. Every step of awakening tears apart the foundation of the Three Realms. When it was discovered that the essence of Journey to the West to obtain scriptures was to fill the black hole of cause and effect after the death of the saint, the Monkey King faced the ultimate decision: expose the lie that maintains the three realms, or sacrifice his body to eternally suppress Hunyuan? This battle spanning the thirty-third heaven to kill the master and achieve enlightenment will eventually rewrite the history of history.
