Review Detail of luksin in Everyone Has Four Skills

I'm 200 chapters in and there is one huge inconsistency, they mention that the world is in a post-apocalyptic state. According to many people there is a "border" between monsters and civilization, but currently there has been no fights against monsters. The only instance in which the MC fights a monster is at the beginning and even then its mentioned later on that it was a tamed beast. So far its all conspiracies between human powers, royal families, corrupt politicians, criminals, etc. The MC just goes on missions to clean up human society, there is no trips to the wilderness to push back the border or explore the rest of the world, which according to his teachers has been taken over by strong monsters. I thought after the firearms army ark, it would change but its more conspiracies, royal families, school competitions. I don't know if it changes later on, but for now i'm going to drop it.
