My name is Lin Yu, and I am an ordinary private detective Lin Yu. I make a living by taking on some small cases of finding cats and dogs, and investigating cheating. On that day, I received a mysterious commission. The client only left an address on the phone and asked me to go there to investigate a bizarre disappearance case. Lin Yu came to the address and found that it was a long-abandoned mental hospital. As soon as I stepped into the door of the hospital, a gloomy atmosphere hit my face, the lights flickered, and there were still some strange graffiti and bloody fingerprints on the walls. The story will unfold from there...
Purpose: In the layers of fog in the abandoned mental hospital, explore the truth behind the disappearance case, explore the boundary between "madness" and "sanity", and expose the concealed human nature and sin.
