The security guard has carried the actor inside the box out?
Standing at the door to the autopsy room, Chen Ge turned back to look down the corridor that he had come from. His eyes narrowed. The influence of a dark environment was not that huge on him. I did not hear a shuffling sound, so they should only be in hiding.
Closing the autopsy room door, some rust fell from the frame. The props inside Tian Teng Haunted House looked old. Feeling the rust, Chen Ge stood up and inspected the tools in the room. Doesn't look like these have been painted to look old. They seem to have been taken from an abandoned hospital directly.
For authenticity, some Haunted Houses would use a low price to buy abandoned equipment in bulk and work on them before placing them into the Haunted House, examples being the surgery bed and the electrocardiograph in the autopsy room.
