Oni

talk to the dude with bald head by the gramps who sells armors.
then go to the one who wear weird glasses, the person where you can make cubes with weapons and armor etc.
then get 1 청동건틀릿 3 은괴 and forgot the cubes. It's white one and the purple or red ones. After that talk to the scientist dude again and he makes that thing for you and talk to the bald head once more and yeah finished.
