The supreme devil didn't have a lot of memory about the previous civilization. When the apocalypse happened, he was still a kid. He was rescued by a group of people who somehow joined the group that Alexander Ardagan led.

"We should find other demon kings…" The land demon king suggested.
"Do you think it will be possible? No, each of them went their way one thousand years ago. Finding them is going to be hard even for us." The sky demon king shook his head.
