A hundred years ago, the ancestors of the An family killed the green and white snake fairy who was about to transform into a dragon, and a blood curse has since entangled the descendants of the An family. A hundred years later, the 20-year-old An Xin was selected as a "sacrifice" by the tribe, just to save the life of his cousin who desecrated the snake temple and was hanging by a thread. Cousin An Ning even gained the power to sell her soul and transformed into a snake mother, forcing her step by step into desperate situations. At a critical moment, Qin Yu, the snake fairy who has been guarding An Xin for many years, finally appears. A girl who was abandoned by her family and a snake fairy with only a remnant of her soul join forces to fight against the snake mother and uncover the truth behind the centuries-old blood curse. And when An Xin discovered that he was actually the reincarnation of the White Snake, this guardianship also became a fateful reunion that spanned a hundred years.
