Drake had no idea that Pandemonium's body had a limit of how much he could maintain summoned at the same time, his current limit were three Demon Gates, and at the same time, no more than ten thousand Demonic Beasts and three thousand Demons.
This was a limit nobody could have ever tried to test anyways, a single Demon alone could destroy half a continent's worth of kingdoms, villages, and everything on their wake. An army of a hundred could destroy the entire continent's ecosystem, and thousands? They could probably conquer the whole continent and go for the next.
Yet Drake and his family were doing something utterly impossible and surpassing all limits. After all this training, after making sure to empower their souls, to give them soul gear, and more. They were advancing rapidly. And also Drake's own powers.
