An Invincible Creature with Added Swordsman

With a golden finger, he cuts through the western fantasy world. Mercer traveled to a different world in Western fantasy. His family was poor, his parents died, and only three brothers and sisters were left to depend on each other in the slums. . . His elder brother disappeared mysteriously while rescuing someone while on an outing. Without his brother's protection, Mercer and his sister encountered threats from gangs in the slums. The thugs laughed ferociously and threatened to sell Moses and his sister into slavery. Moses relied on lies to scare off the thugs, and the old man saved by his brother found temporary refuge by joining the swordsman training hall in the city. In the swordsman training hall, Messer used the golden finger to quickly upgrade to gain strength, eliminate the eager thugs, and start his own journey to become an invincible swordsman.
