My Pure Yang Body Attracts Demon Girls

Lu Xun, a cocky demon slayer, thought he was hot stuff—until he met the thousand-year-old White Snake Demoness. One brutal beatdown later, he wakes up bruised, battered, and forced into an engagement with her frosty 400-year-old disciple. Why? Because his rare Pure Yang Body is the only cure for their millennia-old cultivation affliction. Without him, they face agonizing destruction. But here's the twist: the more he's around them, the more his own cultivation explodes! Every \"forced\" interaction makes him exponentially stronger. Can he survive being constantly \"used\" for power, or will he accidentally become strong enough to turn the tables on his beautiful captors?
