OK, so, 30 chapters in, the guy has a monstrous (problematic?) harem of every female races possible, a legion of demon wolves, a freaking gigantic army of OP demon spiders, a ton a enormous killer bees, is allied with a dragon nation, the maou (who is afraid of him) and beastmen, he already has a kid, built a farming village/spa resort... And now, his demon wolves legion started, by their own will, to destroy a dungeon like nothing.
In 30 chapter, the guy has accomplished more than every other isekai MCs COMBINED.
