Beneath the glorious golden armor of Sun Wukong, the Victorious Fighting Buddha of Flower-Fruit Mountain, lies the mystery of the Six-Eared Macaque's tragic death. When he stumbles upon the Long-Armed Ape and the Red-Rumped Horse Monkey secretly discussing the prophecy of “the four monkeys joining as one” in the back mountains, the Golden Cudgel is already at his brother's throat. This fratricidal slaughter uncovers the grand celestial game that the Lingming Stone Monkey has borne for a thousand years.
Guanyin appears and reveals the secret of heaven: only by uniting the four monkeys' origins can the world-ending calamity be suppressed, and Wukong is the key to the formation. The Long-Armed Ape takes his own life, and the Red-Rumped Horse Monkey perishes. The three monkeys weave a lie with their lives, luring Wukong into inheriting the position of the Spiritual Monkey. Only when his Buddha nature suppresses his demonic nature and his spiritual essence is sealed inside the Heaven-Mending Stone does Wukong realize that this so-called heavenly destiny is a shocking deception, paid for with his brothers' lives.
As demonic energy ravages the Three Realms, a youth bearing fragments of the Golden Cudgel shatters the lies. Following a labyrinth of memories, he encounters the fading image of the Six-Eared Macaque calmly embracing death, touches the Long-Armed Ape's still-warm blood, and hears the Red-Rumped Horse Monkey's resentful roar. When the spiritual essence within the spirit stone takes the form of a youth and enters the demonic realm, three phantom figures resonate upon the Golden Cudgel. They are the starry river of Wukong tearing apart his fate.
“With this strike, I shatter destiny and sever karma!” The reborn Wukong breaks the shackles of Mount Sumeru, forging his Buddha, demon, and spiritual natures into a blade that can overcome the calamity. No longer a pawn, he swings his cudgel toward the heavens, with burning peach blossoms and three undying phantoms behind him. He fights for loyalty and love, for all living beings, and to prove that love can rewrite the Heavenly Dao.
