Demon Doctor of the Tang Dynasty

I'm just a little monster, Looking for the direction of the avenue, It's a pity that we can't choose Confucianism, we can't convert to Buddhism, let alone talk about Taoism. These three families don't like demons, they only want to rob the Tang Dynasty that I like. After thinking about it, I can only hold back all other schools of thought and practice medicine for fun. I believe that if I start this business, those guys who look down on demons will go crazy. Don't you believe it? Hey hey hey, it's okay, Because I want to have a good operation on this Tang Dynasty that I like.
