Ghost Knocking on the Door in the Middle of the Night

I'm a police officer, the lowest on-duty police officer. One time the police station was short of manpower, so they sent me out as well. I was curious about what kind of incident it was... After all, an ordinary police officer like me was not qualified to go to the scene. But when I arrived at the scene, I realized that things were beyond my knowledge... It was this police dispatch that completely changed my view of the world, and also changed my future life... This novel and its characters are purely fictitious.
