Yuan Huai participated in his familys trials, but during the trials, villains stole his chance to cultivate immortality. His mother was murdered, his sister was kidnapped, and he himself was severely injured and thrown off a cliff. On the verge of death at the bottom of the cliff, he encountered Sun Wukong, who had been suppressed under Five Fingers Mountain ten thousand years ago. He gained the opportunity to become Sun Wukongs disciple and was reborn. He escaped from the bottom of the cliff to avenge his mother, and with Sun Wukongs help, he entered the immortal realm and embarked on the path of cultivating immortality to save his sister.
