Plot of Swordmaster’s Youngest Son

Jin Runcandel was born into the Runcandel family, the most prestigious swordsman clan in the land. However, despite his noble bloodline, Jin was deemed a failure — lacking talent and strength. His disgrace led to his expulsion from the family and a meaningless end.
But fate gave Jin a second chance. Reincarnated with the memories of his past life, Jin made a contract with a powerful god, gaining the strength and potential he had once lacked. Determined to rise above his former failures, Jin returns to the Runcandel family with a new resolve and unmatched talent.
As Jin begins to establish himself within the family, he faces resistance from his siblings and the family elders. His rise in power disrupts the delicate balance of authority within the clan, creating both allies and enemies. Jin’s contract with God grants him extraordinary abilities, but it also binds him to a mysterious fate that remains unclear. With each victory, Jin inches closer to his goal of becoming the greatest swordsman — but the path is fraught with danger, betrayal, and the burden of his contract.
