Jiang Fei looked into the room through the crack in the door. It was just an ordinary office. There was no one inside, and there was nothing out of the ordinary.
“Click...”Jiang Fei pressed the switch at the door, and the light in the room was switched on.
After the light was switched on, Jiang Fei could see everything in the room. However, there was nothing out of the ordinary. The desk in the room was covered in dust. It was obvious that no one had used it for a long time.
“The sound just now came from here...”Jiang Fei muttered. Then, he checked the room again and turned off the lights and closed the door.
After returning to his seat at the elevator entrance, Jiang Fei was very confused. What was that sound?
Ever since the door was opened once, the sound had never appeared again. Not only that, the entire night was unusually quiet. It was until the next day at nine o’clock in the morning when Eddie took the elevator to relieve his shift.
