The burly man passed by Dudian and pressed on the wall next to the iron gate.
Dudian had seen through the x-ray vision that there was a secret compartment inside the wall which was connected to the bearing and lead wire. As the burly man pressed on the loose wall, the iron gate slowly opened and opened to both sides. There were hidden sharp blades and poisonous arrows waiting to be fired. If someone forcefully broke the iron gate, it would trigger the mechanism.
Behind the Iron Door was still a dark world. Everything was hazy in the darkness. But Dudian could clearly see that there was an extremely spacious room. There were sofas and tables made of animal hair and cloth, there were also several rows of bookshelves and several spacious tables. There were messy papers piled on them. In addition, there were several strange instruments in the open space of the room.
Dudian recognized one of the instruments. It was a microscope.
