Kapitel 1620: More Contribution.

Of course, the demon gods of the Tyrant realm were wrong about the assumption that all of them and the demon gods of the High Heaven realm should possess more energy than Aeternus. In fact, they would be wrong to think that all of the abyss of both realms combined possess more energy than him.

But what else they were wrong about was that the demon gods of the high heaven realm wouldn't have fought Aeternus even if he hadn't gained a lot of power recently. They don't want to break the pacts of the abyssal coalition now that the era of conquest has started. 

They were not going to attack him, despite the fact that they hate him a lot and know one of Aeternus's weaknesses. This weakness is that he has only one body, so he will die permanently if they manage to kill him.

So they have a real chance at eliminating him for good. But they also know of many of his strengths, such as his powerful Supreme Law.
