Discarded Skill Hunter

Han Siwoo is an F-rank scavenger who makes a living cleaning up dungeons after the real hunters are done. Broken weapons, dead mana stones, useless skills—he survives by picking through whatever everyone else throws away. Then a dying hunter passes him a unique ability: Remnant Reconstruction. It can't make him strong overnight. But it can combine Skill Stones and skills he already owns, turning worthless abilities into something entirely new. To everyone else, an F-rank skill is trash. To Siwoo, it's a crafting material. Still broke, still cautious, and now employed as the porter of an absurdly strong swordswoman, Siwoo begins climbing from the bottom one discarded skill at a time. Everyone else hunts for treasure. Siwoo hunts what they throw away.
