Nether Swordsman

I don't know since when, the legend of the Netherworld Swordsman has been circulating in the world. No one knows his name or his life experience. They only know that he owes countless lives. People are like ghosts and angels, and swords are like ghosts. Anyone he wants to kill can never escape. Over the years, the name of the Nether Swordsman has made the entire world fearful, and various sects have become vendetta and hostility against each other. The rivers and lakes then issued a killing order for him, stating that the person who could take the Nether Swordsman's life would be the next leader of the martial arts alliance. From this, a process of hunting down the Nether Swordsman began in the world.
