Review Detail of AJ_Conquer in Restart:Untalented Man

I like reading Kingdom building novels and when this novel started I thought this was one of the best KB novels on web novel but recent chapters has been a huge let down. reading till chapter 350, the MC comes from a modern world yet has not shown any progress when handling diplomacy. I mean the way author has shown how diplomacy is handled by Riz or Rythium kingdom is very basic, even having a minister and ministry to handle external affairs they have not shown professionalism or handled things properly post war. Also why has author neglected the Spy network when crucial information about war and certain things have not been passed back to kingdom, the Inver issue was handled badly. Also the way war was won by being lucky is kinda let down. Hopefully author improves these things ( read other kingdom building novels if you have to).
