looking for great hack n slash online online game

hello im looking good hack n slash type android game. i prefer online and i don't mind if its a bit pay 2 win. i prefer that the art style is realistic, open world, able to explore some dungeons/abandoned facility/house facility interiors(so the world is like skyrim) and the view is semi top view, i also prefer that it is Korean game i kinda not liking western game.
