Geomsulmyeongga Mangnaeadeul

Jin Runcandel was destined to become the head of his swordmaster clan. But despite his best efforts, he's banished for his shoddy swordsmanship. Though Jin eventually makes a contract with the god Solderet and is freed from the curse that hindered his abilities, he meets a rather unfortunate end. In the next moment, however, he awakens as a baby, long before his tragedy began. Armed with a second chance and some new powers, Jin swears to fulfill his destiny and become the ultimate swordmaster.
