Legion-5 shook his head. "I would call them pompous if they didn't have the power and right to be pompous. So they are only confident."
Apparently, the supreme alliance plans to take down the realm tree that the Realm of High Heaven will fight very quickly before others can interfere. They want to do so to monopolize the assistance of the realm lord so that they will be able to create a large batch of world gods through the era of conquest.
If someone else had dared to say that, they would be called out of their minds, crazy and overreaching. After all, how can a single race take down a realm on its own?
But the Supreme Alliance is not overreaching and they are not out of their minds. They control over 20,000 planes in the entire realm and that's only because they are not trying their best. A realm tree without a realm lord will find it difficult to resist them.
