Legend has it that five hundred years ago, the Chu family, a family of monster hunters, was cursed by a monster for generations because of a forbidden love. From then on, the Chu family fell into a dilemma.
Five hundred years later, the curse came true, and now the only descendant of the Chu family is Chu Qi.
Chu Qi inherited all the Chu family's monster-catching skills and became a modern monster-catcher. With her own skills, Chu Qi started her own business of catching monsters, catching and exorcising ghosts in exchange for rewards, and lived a simple life.
As fate would have it, Chu Qi met Jueying, a thousand-year-old monster, and formed an indissoluble bond from then on. The two disliked each other and always fought secretly. However, they did not expect that this pair of happy enemies would unknowingly develop feelings for each other.
Recently, the usually peaceful Youyun City has been undercurrent. Chu Qi discovered that many strange events have occurred, starting from the girl troubled by the nightmare technique, to the grievances between the Hu and Li families, and even affecting Jueying's personal safety. Behind all of this, there is a huge conspiracy...
At the same time, Chu Qi also gradually discovered the truth about the decline of the Chu family. The Jueying beside her was actually the monster that cursed the Chu family back then!
Faced with a family tragedy and the vengeance of annihilation, where will the relationship between the two go?
Facing the enemy in the dark, how should Chu Qi resist the enemy's attack?
