The leader of the righteous path, Immortal Chu Yao, is cold and desireless, and is the white moonlight in the world of cultivation. Her only stain is the traitor who deceived her master and destroyed her ancestors and fell into the devil's path - Demon Lord Xie Yuan. Just as she was in seclusion to enter the realm of ascension, the inner demon came and took the form of Xie Yuan to disturb her Taoist mind. Chu Yao slashed her with a sword, but the inner demons did not dissipate. Instead, they condensed into a three-year-old child, hugging her legs and calling "Mother", pointing at the demonic energy in the sky and calling "Daddy". The little boy possesses the power of both immortals and demons. When he cries, the spiritual plants in the immortal mountain wither; when he laughs, the blood lotus in the demon realm blooms. What's even more terrible is that the child said that he was born from a "divine relationship" between his parents! In order to stabilize this "walking weapon of the law of cause and effect", Chu Yao had to go down the mountain and find her nemesis who was already the supreme leader of the demon world. "Xie Yuan, our inner demon has become a spirit, do you care?"
