Sherlock took out a precious white pearl and said, "Due to time constraints, I'll omit the background information and other nonsense. Simply put, this is called the Doppelganger Precious Pearl, and it's what allowed Samael to walk out of the Spirit World. It isn't very useful to anyone aside from Devil Kings that want to get out of the Spirit World. However, if we use this item as an intermediary station for the Underworld, we can invade the Surface World a few hundred years in advance."
"Invade the Surface World?"
"That's correct!" Sherlock said firmly.
"Without a huge army, we'll be surrounded by humans if we invade the Surface World. With the Doppelganger Precious Pearl, we can set up a Dungeon Core on the Surface World and expand our Dungeon. The most important thing is that we can recruit the Surface World's races."
