So there was a novel about guy that was swordmaster of some kind in modern world that was summoned into a world of sword and magic (or something like that) but he knew that he would be used (?) by royality so he escaped, on the way he meet 2 girls (slaves) and saved them from their master - then he took a part in civil ward in neighbour country where he saved royal faction but was feared by them at the same time and so they were too scared of his power to let him go his way (in case he would turn against them in future) so they gave him some remote barony or something like this that was constantly invaded by magical beast, but was fairly big. Sorry for engrish, ty for help in advance
