Just like the murdered old man (actually his ghost), his body is white, his eyes are red, and his upper body is just flashing. Not terrible. You can go to the murder room to see the murdered person. The ghost looks and dresses like him. If you are afraid of ghosts, you can go up to the second floor first, and then go down the stairs to the victim's room, so you don't have to go through that dark corridor. Also, pay attention to the ghost in the bathroom of that room, don't go in; Don't open the double doors next to the room. That's the door leading to the dark corridor. You'll go to hell as soon as you enter.

If you want to study ghosts, I suggest you play music in crowded places during the day.
