The Strongest Live-In Son-in-Law

Duan Jiuyou, the legendary sect master of the Sword Demon Sect, is framed by others and transmigrates into the body of a live-in son-in-law. Being a live-in son-in-law would be bad enough, but his wife and sister-in-law bully him, too. I’m the mighty Demon Lord, after all! Father-in-law, since you’re unhappy with me, watch out or I’ll make you submit at swordpoint! Wife, since you’re unhappy with me, I’ll just have to make you submit in bed! See how Duan Jiuyou, the mighty Demon Lord, is reborn as a live-in son-in-law, sweeps aside the righteous sects of the world, challenges the Immortal Path, and turns the world upside down with a flick of his hand!
