We searched the whole room from top to bottom but still found no way to access the power source that was powering this basement floor. The other floors did not have power at all, and this one floor alone was enough to take up the two city blocks. I was not sure about the other buildings, but I did not see any stairs leading down to this basement level from another building.
"I think I found something!" Sei yelled out from across the room. Everyone was split up on each side of the room, so it took us all a few minutes just to get to her.
Sei was standing on top of a section of the floor, stamping her foot. She then pointed at the ground and said: "This section sounds different from the others."
I looked down at where she was talking about and scanned the floor. A few inches away from where she was standing, I could see a thin hairline crack in the floor. "So easily missed….." I said while pursing my lips. "Alright, let's try to get it open."
