The demon exorcist literally means to drive away demons. The real meaning is to send the souls left in the world back to the underworld.
Why not call it the Demon Sending Master? That's because the leaders of the three major demon exorcist sects felt that sending the demon exorcists was too hard to say, so they simply called them exorcists.
Speaking of the three major sects of demon exorcists, they refer to the Zhenyang Sect, the Xuanyin Sect, and the Yin Yang Sect.
Zhenyang Sect uses the power of gods to send away various ghosts and monsters. You can combine with gods or demons to increase your spiritual power.
The Xuanyin Sect uses the power of ghost soldiers from the underworld to fight ghosts back to the underworld. The descendants of the Xuanyin Sect are demon exorcists in the underworld and civil servants in the underworld.
Yin Yang religion does not belong to the jurisdiction of the Yang world and the underworld, and is a gray area. The descendants of the Yin-Yang Sect often send ghosts from the Yang world to the underworld in some special ways, but most ghosts are beaten to half death before being sent back to the underworld. Yin-Yang teaches that men are weak, and most people only have a son after giving birth to three daughters. Therefore, in order to reproduce the Yin Yang Sect, the tribe allowed polygamy. However, under socialism, monogamy was the only option, so there are very few descendants of the Yin Yang Sect.
Not to mention the Yin-Yang Sect, there are even fewer descendants of the Xuanyin Sect and the True Yang Sect. At present, the only descendants of the three religions are the Luo family, the Cai family, and the Murong family.
Taboos for exorcists:
One: The ghosts must not be completely destroyed, but must be sent to the underworld intact. (The descendants of the Yin-Yang Religion do not need to abide by this point)
Two: Do not use spiritual power to deal with strangers.
Three: Don't ask too much about the ghost's life. (The descendants of the Yin Yang and Xuanyin religions do not need to abide by this point)
