In modern society, spiritual power has decreased. Some monsters have gone into the mountains to practice, and some have entered human society.
When there are more monster clans, more troubles will be caused. So the human race set up a demon management office to deal with cases where demons hurt people.
The seventh eldest son of the Blue Fox family, Hu Qitian, is a vixen who has entered human society. When he was a child, he worshiped a bald Taoist to learn the art of catching monsters, and he specialized in taking orders to catch monsters to support his family. Therefore, he was also regarded as a traitor by the rebellious demon clan.
