The peak of strength in South Korea is the Esteemed Martial Lee Clan. In that martial clan, Lee Cheol was looked down on and chased out because of his status as an illegitimate child. In order to survive, he lived in shadows, but he was chased down and killed because of his family's schemes. He was then granted a second chance—regression. Using his "ability to absorb the memories of a weapon" as a foundation, Lee Cheol would train and go down a path of struggle. Persistent competition and schemes regarding the right to inheritance, attacks from other races and monsters in dangerous, unexplored lands, and even local clashes related to his family's internal struggles... His growth would bring about these things, bringing hardship upon Lee Cheol. Life itself would be a struggle for Lee Cheol, and this is his destiny. But in order to protect himself and his surroundings—in order to protect everything—as the fight continues, he'll unravel secrets from his past life, one by one...!
