Book of Demons and Ghosts in the World

I am a magician who specializes in dealing with "unjust things" in the world - if people are unfair, I will harm them; if monsters are wronged, I will also pacify monsters. The world is becoming increasingly turbid, and demons and ghosts no longer hide in the mountains, but seep into the streets and streets, living next to people. My name is Chen Pingan, and I am a "harmony master" from my ancestors for three generations. My job is not to slay demons, but to mediate. When the fox girl is deceived by the unfaithful scholar, when the house monster goes berserk due to internal fighting in the family, when the river uncle has no place to live due to the relocation of the river course - people look for the government, and the monster looks for me. I use an ancestral ruler to measure right and wrong, use a volume of "Hundred Demons Book" to deduce cause and effect, and use the simplest principles in the world to solve the strangest puzzles. Demonic matters are human affairs. To solve the demon, you must first solve your heart. The world is about to be in chaos, and hundreds of ghosts are walking at night. And I just want to guard a small yin and yang shop, between humans and demons, Seeking justice and a way to survive for this crumbling human market.
