Paranormal Files My Last Yin-Yang Detective

When my grandfather died, he said that he would burn these belongings of his, but I hid them without thinking and spent a lot of time studying them. It was this decision that changed my life... My name is Chen San, the last Yin-Yang detective in the world. I have seen hundreds of ghosts walking at night, and I have also seen evil ghosts resurrect, but if you want to ask me what is the scariest thing in the world, I will tell you the answer without hesitation: "Human nature". Speaking of detectives, I think you may first think of crime-solving experts such as Conan or Qin Feng, Tang Ren. In fact, they and I have the same job and hobby in a substantive sense, which is to solve cases, but the case-solving in my words is a bit special, because... I only solve cases for evil ghosts! Maybe some friends are confused about what Yin Yang Detective does? Give me your time, and I will use my life's experience to reveal the veil of human nature to you. Please be patient and listen to me slowly... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
