Mysterious World Hidden Beneath the Sand

September 5 I was walking along the ridges of the sand dune when I found a strange black object shining beneath the sand. Like a moth attracted to light, I went up close to the object and reached out my hand. I walked inside, cloaked in darkness. The mysterious place consisted of many floors, connected like a maze. Though I had no idea where I was, I knew that it'd be difficult to find what I want. However, I couldn't find the exit. Feeling trapped, I started running with the compass in my hand. The path to the upper floor was destroyed and cut off. When I tried to look for another way, the floor collapsed and I fell through. This was the end. I closed my eyes and grasped the compass with all my might. Will it hurt? Of course... Poof. Huh? The rock floor was softer than I imagined. I looked around in daze to find myself out in the desert.
