C1896 Spongebob Crystal Iron Cage
This room is very big, and with normal walking speed, it'll take a quarter of an hour to get to the deepest part of the room from the outermost area.
In the deepest part of the room, there was a metal cage made of a special material. On top of it, there was the aura of Chaotic Divine Powder, and it was a light blue color.
