The Record of Sinister Cases

My name is Wang Yang and I am a private detective. I used to not believe in ghosts and gods, I only believed in the chain of evidence. Until I received a commission: a man who had been dead for seven days sent a voice message to his daughter on time every morning. The voice was generated after his death, and the sending device found no such number. Seventeen minutes of laundry surveillance were missing, and there was a girl no one had ever seen in the reflection on the glass. Someone told me that it was called "objects outside the case" - it was the death that was covered up, the identity that was deleted, and the fragments of the case file that reality refused to admit. They will crawl out along with mobile phones, surveillance cameras, navigation, and smart door locks, completely eliminating a person's existence. I can touch the remaining truth in the physical evidence, hear the deleted sounds, and see the erased images. The price is that my name is slowly disappearing from everyone's memory. My brother disappeared six years ago, and everyone said he ran away from home. Now I know that he is not gone, but has been erased from the case file. I want to get him back. Even in the end, I myself became a person outside the case file.
