After meeting Sima Jiao, the master of Gengchen Immortal Mansion, who has been sealed in the mountains for five hundred years, and Liao Ting Yan, who unexpectedly came to the world of immortality, he was overcome by his "salted fish" (a term used to describe people who are self-deprecating and have no pursuits) instinct of wanting nothing. From then on, Liao Ting Yan began to guide Sima Jiao to be good step by step and became the person who changed him. During the process, they fell in love and experienced a love-hate entanglement spanning three lives in the fairy palace, the demonic realm and the human world. In the end, the two chose to protect their love and maintain peace in the three realms.
