Reborn as a Swordsman Genius from an Enemy Country's Family

The overall story is quite smooth [eating melon], except that the protagonist's personality flaws are relatively large, but combined with some of his previous experiences, it is still acceptable (barely rationalized). The content is a bit rough and not delicate enough, but there is still room for improvement [love].

It's pretty cool, but the current division of combat power is not very clear. Is there any correlation between the levels of each profession?

Come on, author, it's very nice.
