After leaving the room, Shang found himself in another long hallway, and this one was even longer than all the other ones.
Shang estimated that it was over 500,000 kilometers long.
With the previous hallways, Shang estimated that he was beneath the Eternal Ocean right now.
Finally, Shang reached the next door and opened it.
Library.
There was a humongous library on the other side. It wasn't as big as the Lightning Emperor's library, but it still had about 10% of its size.
One had to remember that the Lightning Emperor's library was probably the biggest one in the entire world unless the Archivist had his own library.
10% of the Lightning Emperor's library was already very much.
Shang slowly walked through the library without touching any of the old tomes.
The library was several kilometers wide, long, and high.
