Author better delete the fact that he said the MC was both a hero and a sage , he is clearly being too retarded for someone who claimed to have lived twice. A sage is wise, a hero is powerful, being cautious and resourceful should be their acquired traits, and here this guy, not only having no common sense, he's not even trying to check what's the standard of his world (which even becomes more questionable, given he's 15 years of age, what did he do in that normal village for 15 years for not even having at least some inkling about common sense. Unless it was a village of OP heroes or something, this should never happen ).
