A Bad Situation.

Aeternus decided to leave too. There's no use staying here anymore. 

"I am glad that I came." He said to himself as he entered the purple energy sea.

This meeting was eventful and very useful. He learned a lot of things. He knows now that he has not been suspected yet of being a king of kings. The demon gods would have never allowed him to join the coalition if they suspected him. In fact, they wouldn't let him talk at all. They would have grabbed him and inspected him down to his soul. Then they would have eaten him.

"I have also found a worthy foe. I wonder how it will feel to tear the crown of a king of kings out of their soul and absorb it?"

He also learned that he might not be the only demon king of kings. He noticed some odd demon kings who came with their main bodies and also possessed a heavy presence. It can be easily mistaken for them being very strong. But he knows better than that.
