Sun Wukong was suppressed and killed by Tathagata Buddha after he distinguished the true from the six-eared macaque. He was supposed to be in despair, but he was accidentally protected by the Chaos Bead (this bead was originally the Hongmeng Bead, and was downgraded from the Hongmeng Treasure to the Chaos Treasure due to damage during the Hongmeng Catastrophe), and traveled through time and space back to the beginning of his birth. From then on, he made up his mind to overthrow the gods and Buddhas in the sky, go to Lingshan Mountain, and personally find Tathagata Buddha to settle accounts.
