@BigCoffee True. I hope that's why it's called "The
scholar's reincarnation", and we get to see him struggle with politics through involvement with the princess and such.
In the matter of martial arts, he's pretty much already a god, since he's stronger than he was in his previous life as THE supreme master in the craft. Sure, he does get noticed by his former enemies (he doesn't exactly hide his identity all too well), but they can barely even dream of being at his level (read: like ants to an elephant). If anything, the only way they could take revenge on him is by playing it smart and attacking his family/clan/territory.
Which is why I'm kiiinda hoping this last arc's villain will at least be a clever guy. He does already have the looks of a fox, anyway. And in manga/anime terms, that would mean he should be a very tricky enemy. Although it'd be a bit boring if the story will follow the cliché villain-of-the-season structure. Hopefully, this enemy will last longer than one season, especially if he's a bit smart.
If you were asking this as a curious new reader, then I can say season 1 has been interesting, since it focuses on his new family life (to which he has to adjust as being a former complete loner). Also, his (new) father nurtured him as a scholar, so that's still an open job window. He does fight from time to time 'though, and as you can imagine, that's pretty much a curbstomp fest. But hey, he does use his brain, and as the son of an important merchant family, he needs his tactics and social networks to stay afloat.
