Good ideas and story, horrible pacing, horrible dialogoue, horrible story telling, pretty bad characters. Sum it up and you get a bad manga, worth a 4 rating just for the potential. It could have been a very good experience, if only the one resposible with the story would have been capable of narrating, but it seems like this wasn't the case. We got at least 15 chapter worth of action and plot cramped in 4 so... not very fun, as you can guess. The only saving grace for this manga was the story, and maybe the MC, but aside that everything was pretty bad (and theart was mediocre). Not even the characters are worth liking, aside the MC there's nothing new to them, instead we even got a mom obsessed with his son (almost crossing the incest line) and a female hero-descendant with a basic tragic backstory that falls in love with the MC in 3 chapters because he's nice.

So, would you gain anything by reading this? Maybe just a bitter feeling for the wasted potential of the story, but aside that, nothing.
