It's fucking hilarious how ignorant he is of his own power. Like how he thinks it's cause he had his past lives worgh of combat knowledge that they were surprised. I bet his master was like the grandpa from wiseman's grandchild and he was like the former hero or something.
I don't care about anything other than Mc having a Fun time of being ignorant and naive cuz its ok since its gud in this kind of manga not the other types of shit manga
Wants to live a simple life, doesn't wear a mask, doesn't change their name, doesn't work unseen, how does he think that's going to be different from the last 2 lives?
He is op as fuck, but if you think about it, he has 200+ years of training (he's had 2 previous lives) of which he's op in both. It only really makes sense that his common sense and lack of common understanding is so out there.
