Baek Woo-Jin is the youngest son of a renowned swordsman family who has neither talent in swordsmanship nor an impressive Aura, despite trying harder than anyone. Although he was dishonored by his own family and killed, he reincarnates as the owner of a Magic Sword. His only goal is the destruction of his own family. (Source: Naver, translated)
