Black snakes cannot cross the sea. Jin Hai, originally an ordinary female college student, survived a car accident. Unexpectedly, she had the ability to open the door to the spiritual world. She became a "Spirit Ji" and worked with her boss Xu Nuo to solve supernatural cases and became famous in the spiritual world. But what Jin Hai doesn't know is that her identity is not that simple.

Because of this, the gray atmosphere can be exploited.
