Chapter 463: Ghost City

The Nether Realm... A Realm that was much bigger than earth was so vast that just the area covered by the outer layer was twice the size of Earth's total area!

It wasn't easy to go from one later to another layer as it was equal to traveling circling the entire earth!

Fortunately, the beings in the Nether Realm weren't backward. Despite the absence of spiritual energy, they had found a way to increase the speed of travel between places. 

They couldn't use spirit formations that ran on spiritual stones since they were useless here. It was precisely because of that, they found another way! Using the undead!

There was an undead species that could use teleportation, without magic! The species was mentally weak, but had strong mastery of spatial concepts. 

In the world, every important place had a few people from the Undead Clan who could use teleport to other locations.
