Review Detail of Higgs in The Insurrection of the Inept Hero

The story has some good potential. Good idea even if its a bit cliche, its quite entertaining. The problem is the leveling system. The level range from the kingdom the hero was summoned at was so far away compared to other places like maroon city. There should have been a clear "Max level" if you will or a level range of people at the apex of strength residing in that world but what you see in the story is one kingdom having people 1-100 while other cities have people 4000 and up in levels. Its sounds so weird. If the author had given the level of usual knights or kings and court mages maybe then it would've been fine or if the level range would have been more logical.
