In a remote town called "Yin Fu Town", an ancient and strange Taoist technique - "Yin Fu Technique" is spread. This technique can communicate yin and yang, and even tamper with life and death, but the cost is extremely high. If you are not careful, you will attract evil and backfire on yourself and even the entire town. The people in the town kept it secret for generations, maintaining a fragile balance until a series of bizarre deaths broke the peace.
