What is the prototype of the exorcism comic novel?

The comic novels of exorcism department have no prototype, and they are all fictional.

During the Tang Dynasty, ghosts and gods were deeply rooted in people's hearts. God Buddha, who does not hear its voice or see its shape, has left immortal Taoism and Buddhism on earth. Demons, appearing in the middle of the night, charm all beings and harm the people. Mortals, painstaking cultivation, or keep the Tao to get rid of demons, or pursue power and profit.

In the end, this balance was broken during Tang Zhongzong's rule, and outsiders degenerated into this world, colluding with powerful people and causing trouble in state affairs. As a result, Sheng Yuan, a Taoist genius, took charge of the exorcism department of Jinwei, which came into being to deal with all kinds of ghost events, protect the people, and expose the conspiracy to protect the Chaogang.
