Common Sense Took a Back Seat...

Wang Chao maintained eye contact with me as he reached out behind him and placed his hand on the wall.  All of a sudden there was a rumbling sound as a section of the wall lifted up.  My forehead scrunched in confusion. How was this possible? Was it electronic? Where did it lead? Why the fucking Hell did they even have this in place here?

 

"There is a lever," said Wang Chao as he pointed to the section in the wall that, upon closer inspection, had a small switch in it that was barely noticeable to the naked eye.

 

"Well, that's useful," I said impressed. That answered the first two questions, but I still had no idea where it lead to.
