I like the fact that only this manga portrays the MC as very close & constantly communicating with the goddess/god that blessed him. Not many MCs do that.
what does a hot spring have to do with a criminal investigation?
"the water is so good I will declare your friend innocent"
That knight family worked for the noble for generations, either Howard knew full well or he looked the other way while dozen of people were kidnapped, tortured and disposed. There is no way that the personal guard didn't knew anything.
This MC never used his brain cells. He has a navigator, his OP magic and physical strength, appraisal, internet that let him buy, etc. But he never seriously practice his magic and strength. Also, he didn't research about the new world he lived in. He could literally make a new village, kingdom, or what not an empire from scratch.
