The great disciple of the Demon Sect came out of the mountain and caused a catastrophe in the martial arts world. One is a weak scholar who does not know martial arts and comes from a noble family; the other is a peasant boy who carries hatred and worships the devil's sect. The two people with very different backgrounds became partners by chance. After going through hardships and experiencing adventures, they finally came together to take revenge. Good and evil have not been coexisting since ancient times, but the righteous can also be possessed by the devil, and the devil can also be corrected. He walks the rivers and lakes with a piano and a sword, creating a legend of swordsmanship.
