A New Hobby.

Aeternus looked at the empty plane, which had to bear the consequences of his dangerous attempt to fuse with his energy. 

It made him say in awe, "No wonder a single demon god can take on a plane on their own."

There are no more animals or plants in the area around him. That area is two-thirds of the total area of the plane. It is completely empty of all life. No one would think there were two armies fighting in this place a few minutes ago. And this is just from the power of his mind without using Chaos energy. 

He said in appreciation for his new strength, "I am not a demon god, but I don't think I am lacking compared to one. I don't need subordinates anymore."

He is not concerned at all that all his subordinates are gone. He spent a lot of time and effort on them, but they are gone now. But it is not a waste of his time and effort. The strength that they acquired through him has been returned to him.
