As Lin Mu continued to observe the Spatial planes, he started to learn more and more.
The next thing he saw was the Habitat Formations coming into play.
They first created a stable layer with formations on which earth started to appear. This layer of earth was nearly a kilometer thick and extended for tens of kilometer as well. The earth was just like normal earth and had a mix of rocks and other materials mixed in it.
If one looked at it they would find it to be no different than the normal earth on Rust Sky world.
Once the stable layer of earth was created, the ground was formed.
Next thing they needed was some light!
While most immortals could use their Immortal sense to 'see' it was still not good for there to be total darkness there. The issue with light was easily solved by a simple Sky Illumination Formation.
