The story of A Yin, a diligent Shuining Beast, and Gu Jin, son of the true God whose magic power was sealed. They met each other by accident and have embarked on the journey to find Feng Yin's Immortal Essence.

Feng Yin (Zhao Lu Si) is a female spirit who has reincarnated into a difficult predicament. She learns that she may be the incarnation of a powerful goddess - or she may be a lowly spirit who has actually displeased the most powerful deity of them all. The only way to find out is to collect the pieces of her immortal essence. Fortunately, perhaps, she is not alone in her quest. Also searching for the essence is Gu Jin (Wang An Yu), the son of the "true" god. Gu Jin has problems of his own to resolve, and his relationship with Feng Yin is complicated. The duo once had a master-servant relationship, but this has since been broken. Since then, he appears to have developed feelings for Feng Yin, who also admires and trusts him. Could love help them find a way to stay together - and solve the mystery of Feng Yin's true identity?—Rakuten Viki
