The Monkey King, whose ancestral home is Dongsheng, China, was born out of the immortal stone. Because he led a group of monkeys into water curtain cave and became the Monkey King, he was honored as the "Monkey King". After worshipping Bodhi as a teacher, Qian Shan was named the Monkey King, and learned the superb spells of the earth demon, such as seventy-two changes, somersault cloud and immortality. The Monkey King, whose magical powers are just emerging, first made a scene in the Dragon Palace to get the golden hoop, and then made a scene in the underworld to check the life and death books. Later, he was blessed by heaven and was named Bi Marvin. Knowing that he was in a low position, he angrily returned to Huaguoshan, forcing the Jade Emperor to make him the Great Sage of Qitian, and set up the Great Sage of Qitian in heaven, ordering him to manage the Flat Peach Garden.
Because of drunkenness, I disturbed the flat peach banquet of the queen mother, stole the elixir of the old gentleman, and became an indestructible body. By mistake, she was turned into an alchemy furnace of Taishang Laojun. Later, it caused chaos in the heavenly palace. Hundreds of thousands of heavenly soldiers, heavenly generals, four heavenly kings and twenty-eight stars can't beat them. Later, he lost a bet with the Tathagata, and was crushed by the Five Elements Mountain (renamed Liangjie Mountain in the Tang Dynasty) abandoned by the Tathagata, and repented for more than 500 years.
