Absolute Sword Sense

Soh Woonhwi was the black sheep of his family—given up on after his dantian was destroyed and forced to serve as a third-rate spy for the Blood Cult. During a mission to retrieve a legendary sword immortal's secret records, he is killed. But instead of death, he wakes up ten years in the past, on the very day he was kidnapped. Armed with a mysterious new ability that allows him to hear the voices of swords, Woonhwi now has a second chance to change his fate and rise from the ashes of his former life.
