The years spent in the Outer Lands benefited both Noah and his pack. He quickly learnt how to use his power better, and his underling improved under the constant influence of his aura.
The Demonic Sword and Night took a while to reach the eighth rank. They both had Noah's aura and methods at their disposal, but they still required a few decades to approach the breakthrough.
The Demonic Form didn't share the same difficulties. The parasite fed on Noah's power, so his breakthroughs had ended up accelerating its growth.
His underlings grew even faster than his abilities. Noah's ambition seeped into the ground and forced it to produce better nutrients. His aura also covered the surface and brought benefits to all the magical beasts that lived there.
The creatures that managed to evolve developed the ability to fly as their level increased. Also, most specimens in the lower and middle tier reached the upper tier and approached the peak of the seventh rank.
