I Use Sword Bones to Cultivate Ghosts and Immortals

Everyone says that at the age of 22, Ji Wang is a master of swordsmanship and is unparalleled in the world... But who knew that he only had three years left in his life? In order to save his sister, he burned his life span, bloodbathed the immortal sect, and finally died of exhaustion. When he opened his eyes again, he crawled out of the grave and found himself in the unpredictable land of the underworld. He used to be a swordsman, but now he has become the lowest "earth soul", not even qualified to become an immortal. There is only a faded red rope tied around the wrist, engraved with a sword and a peach blossom... "After drinking the water from the Yellow Spring, all the past will be forgotten." "They said I was a poor man and laughed that my path to immortality was cut off." "But I don't know that my sword once made the Tianhe hang upside down."
