The secret room was about hundreds of square meters. The thick walls were made of hard black bricks, and the four walls had demon characters engraved on them. Several burning magic torches emitted light, but they could not illuminate this secret room at all. There was a weird, dark atmosphere in the room, and a strange force field spread over the room, seemingly protecting and covering this place like a barrier.
Roy controlled the Demon Eye and did not dare to get too close. He found a corner where he could observe and let it hide.
The secret room was currently empty. There was only a giant demon skeleton on one of the walls. This skeleton's demon horns were still there, but its face had three hollow eyes, and the third eye was at the center of its forehead. Roy did not know what race this demon was before it died.
