After Sun Wukong protected Tang Monk from fetching scriptures, he was named the Victorious Buddha. Returned to Huaguo Mountain to reunite with Monkey Housun, but in the eighteenth level of hell.
The resentment left by Sun Wukong when he became an immortal grew quietly in the underworld, constantly absorbing the resentment in the underworld and becoming stronger and stronger.
He developed the ability to reach the sky, transformed into the Dark Sun Wukong, and called himself the Demon King.
The devil controls the underworld and leads the ghosts from hell into the three realms. Break into the sky, force the Jade Emperor to death, and control the immortals. He also led the ghosts to attack Lingshan Mountain, where the Buddha died in battle and all the Buddhas were destroyed. He also released the undead spirits from the underworld and disturbed the human world.
When the undead disturbed Huaguo Mountain, Sun Wukong learned about the chaos in the Three Realms, and led the monkey Sun Wukong to defeat the devil all the way.
