The rusty iron door made a tooth-grinding sound. Chen Ge pushed open the security door of Room 404 and stepped in. Behind him, there was a loud "bang". The door was slammed shut, and the sound of the door lock being locked automatically echoed in the silent corridor, like some kind of beast closing its fangs. Chen Ge tried to twist the door handle. Not moving at all. This place is definitely not clean. He let go of his hand, and instead of frantically knocking on the door to ask for help like ordinary people, he took out a strong flashlight from his backpack and calmly shined it around him. The light beam pierced the darkness, and dust visible to the naked eye floated in the air. The room was not big, with one bedroom and one living room. Large areas of the wall peeled off, revealing the black cement inside, like patches of poorly healed scars. There was a strong musty smell mixed with a faint smell of rust.
