The Twilight Rain Saber

A blade that has never tasted blood, and a swordsman who has never killed. Li Muyu keeps to the common streets, drawing his blade only to save lives. When his fated enemy returns, he must face a choice between the blade in his hand and the path in his heart: should he keep his vow never to kill, or break it for the sake of all living beings? In this martial world, the sharpest thing has never been the blade.
