When I woke up, I found myself naked, lying on a stone bed covered with mysterious runes. When I got up, I found that my original 4x5 square meter bedroom had turned into a circular secret room with only a five-pointed star skylight above it. The surrounding walls were made of worn-out bricks spliced ​​together, and there were some things placed on the ground around it. I was very puzzled, but I still searched for these things exploratoryly, and finally figured out my current situation and situation, so I continued to explore this strange place.
