This is basically the exact same story I've already read several times. So at best, this deserves a rating of 5, because it has no unique elements or twists.
It's the same extremely OP MC that for some reason doesn't realize he is OP. Surrounded by women that want to fuck him, without realizing it.
Strong enough to enact real change and embark on an epic journey, but instead just wants to chill out and pick herbs like the extreme loser he is.
An MC like that is boring, and thus the story surrounded such an MC will be boring.
