Of course, an easier method would have been to simply allow themselves to be caught, or bow to one organization or family or whatever, gain information from them, and try working from the ground up like a normal person would as they adjusted to the Upper Galaxy, which would in turn also grant them a level of protection and guidance.
But the Demon King and the God were two beings who had lived for over a billion years, their pride was immense, although people like the Demon King hardly projected it outwards in an obvious manner. Their confidence in themselves to always survive, rise, and conquer was too deep-rooted, far too ingrained within their very existence. They had been in power for far too long, one ruling over an entire Galaxy, the other ruling over an entire Realm that had the entire Galaxy on constant defensive mode.
Did anyone truly believe these two beings would set aside their pride and bow to another person after staying so long in power? Definitely not.
