Review Detail of AJ_Conquer in Reincarnated as Napoleon

I really liked the other 2 novels written by the author but I don't know why but this novel has sort of been a let down... in the starting only I don't understand how the character Nepolean gets admission in the military academy also how can his parents let him travel alone so far to Paris when he is not even 14-15. I don't think it was normal for kids to travel that far alone at that time period as it was very unsafe. Also the way he introduces technology is way too fast, besides before MC transmigrated he was not brilliant in wars and even though he knows history how can you show him win every battle? That's too much of smooth sailing without much of a struggle. It's like he can't do no wrong in the world, he is not god nor has super powers so why does he always gets what he wants?
