This Needs Serious Editing before becoming readable ! So many grammatical mistakes ! World background is almost non-existent ! Too much focus explanations on every useless thing(explanations mostly are all boring so they must explain necessary stuff and shorten it as much as possible leaving place for plot, but here its complete opposite), but when it comes to about necessary things giving explanation about how mc chose and worked in his now chosen profession with all damn time skips and especially power levels there is None. Since they were in orphanage there was never mentioned what power levels they reached accurately and on what power levels were their enemies. Action and Skills needs also huge improvement and better explanation, but with this horrible writing quality everything is Useless, Unreadable !
