The catastrophe of the three realms, the destruction of the Demon Lord Ni Lun, and the Nine Nether evil spirits scattered and fled into the human world. Chong Zi is pure and kind, but she is the daughter of Ni Lun. Because she was saved by Yun Jun Zi Chu Bu Fu, she was determined to study in Nanhua, but she was rejected because of her natural evil spirit. Min Yunzhong, the superintendent of Nanhua, declared that she would definitely become evil. At the critical moment, Luo Yinfan, the venerable of Chonghua, stepped forward to accept her as a disciple, and from then on Chong Zi became Luo Yinfan's only disciple. Chong Zi relied on Luo Yinfan and only wanted to accompany her day and night. Luo Yinfan also promised to protect Chong Zi. However, he could not resist Jiuyou's conspiracy. Luo Yinfan saw Chong Zi imprisoned but was powerless, and had to "finish" her personally for the sake of the people of the world. Above the clouds, Chong Zi appeared in Nanhua again to become a disciple. Luo Yinfan recognized her at a glance. In order to protect her, he sealed her evil spirit and kept her by his side, and the two continued their relationship as master and apprentice. However, fate has changed, and Chong Zi still cannot escape the manipulation of those with ulterior motives. She has become the target of public criticism and has fallen into the evil spirit in anger. It turns out that Chong Zi is the daughter of the former Jiuyou Realm Lord Ni Lun, born with evil spirits, and destined to be an evil spirit. Fate plays a trick on them. One is the Zhonghua Master who is committed to saving the people of the world, and the other is the Jiuyou evil spirit who is born with evil spirits. They love each other helplessly, but they kill each other helplessly. The master and the apprentice are in opposition, but it is difficult to break the love. But in the end, both of them sacrificed themselves under their firm belief in goodness and fulfilled their love and the people.
