I guess author is trying to change the world so that humanity has strong fighters
till this chapter all we saw was how weak they were compared to mc, at all times, even when going to the most deadly places (like that gem island) they werent able to do near anything and every responsibility fell on mc's hands
well about time I guess, but I would've preffered an actual reason for humans to have strong fighters, rather than "we didnt see them until now but humanity has strong fighters" kind of explanation
btw dont misunderstand I know how strong the mc is, and comparing him to normal humans is pointless, but regardless they were useless in all important events (non-existant in most)
