This is a strange and bizarre world, where the strong can move mountains and fill the sea, while the weak can live like ants. Li Yunfei, a blind orphan from a mountain village, although physically disabled, had a grandfather who was really kind to him. He originally wanted to live a life in paradise. However, a man-made disaster broke this peaceful life. Grandpa's body was wiped out because of the strong man's battle. Even they didn't know that the blind boy's grandfather died in this battle. The blind boy looked at all this and felt angry in his heart. Since there is no justice in this world, I will find justice myself. From then on, there is a blind boy practicing swordsmanship in the world.
