The Library of Infinite Beginnings
We entered the large tower before us, known as the Library of Infinite Beginnings. The automatic doors slid open, and we walked inside. The interior was beautifully delineated, with lots of space all around so that it didn't feel cramped like lots of libraries on the outside. There walls of this cylindrical structure were all transparent, so they were more like windows, really. There was a massive exquisitely designed glass spiral staircase in the middle of the first floor, leading upwards. The floor above us was also transparent - we could essentially see through it and even beyond to floors further up, but curiously, we couldn't see any actual people.
"Is there no one on the upper floors?" I asked.
Old Man Leng chuckled. "Nah, they're there. Ya just can't see them from down here."
"But...the ceiling above us is transparent. I can see all the bookshelves and even other floors further up," Feng Mian mused.
