Surprisingly, it turns out that the place they were in was right below the white tower. It's just that Rean couldn't tell which side of the tower it was. Levid then nodded in response and guided Rean outside the building. With that, Rean was finally able to see the area where the formation was. "That's quite a big formation."
The area below was at least a kilometer wide. However, it didn't go very deep. After all, the Upside Down World had a barrier that prevented anyone from escaping. 'Speaking of the barrier, I guess that hole in the center of the formation is connected to it.'
Surprisingly, Rean was right. At the center of the formation, there was a hole which one could see the barrier from. Then again, Rean couldn't tell what was being done there as he was too far away.
