At this point he's just humiliating himself and he relies too much in his skills and his sword but without hard work you're just brawns without brains basically.
Nonetheless the story is still satisfying because i get to see their reactions. lol
Man, I'm starting to actually feel bad for this so called hero now. The fuck kind of logic was he going for though? He increased his power but it's useless if he's still slower than a turtle compared to him.
All joking aside, I love how the author points to the other dude being a completely normal isekai protagonist. The legendary sword also turns into a little girl for his harem - because of course it does. It’s those little touches I find funniest tbh.
