In the eyes of humans and other species, the demons of the Abyss were all chaotic and disorderly, but this was actually a misunderstanding.
The reason why such rumors spread was essentially that most humans could only come into contact with low-rank and middle-rank demons. The demons of these two ranks were indeed bloodthirsty and violent. There was no order to speak of, only destruction and ruin.
But it should be known that even unintelligent animals and wild beasts would have certain rules in their groups, let alone intelligent species like demons.
However, the order between demons was usually some specific rules formed over tens of millions of years. It was not like humans, whose laws had been engraved into words and passed down. Moreover, demons would only obey these rules when necessary. If they were powerful enough that no one could restrain them, they could also ignore them.
