The nine-tailed fox Fu Lingyue, who has always been accustomed to wandering, borrowed the help of a girl who was forced to get married, took away the groom on the wedding night and helped the girl escape from the magic cave called marriage.
That day, when he was finishing the girl's affairs and preparing to absorb the groom's demonic power, he suddenly encountered Yin Lihan, a soul-collecting ghost who was a white snake and wandered between the three realms. He couldn't help but compete with Fu Lingyue, who had used half of his demonic power to form a seal, for the soul of the eldest son of the Zhang family.
The turning point came when Yin Lihan said that Fu Lingyue could take back half of his demonic power when he met him two hundred years later, so the two formed a seal of life and death for two hundred years, and they were dependent on each other for life and death.
Yin Lihan took him back to his stronghold. Fu Lingyue put aside all his past and opened a medical clinic opposite the stronghold according to his wishes. It healed people openly and treated demons secretly. The business of the medical clinic was far more than just treating diseases. Fu Lingyue returned to his old business and simply helped all kinds of demons and ghosts to solve difficult problems. At the same time, he thought about leaving Yin Lihan immediately after two hundred years.
There seems to be something hidden behind Yin Lihan - Fu Lingyue only knows his code name, Soul Collector, but knows nothing about his past.
Fu Lingyue helps people who become cocoons to become butterflies get rid of the curse of having their wings shattered, and helps book demons in dry lands solve the mysteries in the thousand-year-old book.
But behind the scenes, there is a bigger picture unfolding.
Concept: The interweaving of ancient Chinese proverbs and fantasy, the atmosphere of the three realms where many monsters and people are linked together.
