Imprisoned by My Traitorous Disciple, I Became Her Cultivation Furnace

[Multiple heroines + coercion + protagonist torment + male master and female disciple + rebellious disciple who seduces her master] Qin Jiu was a demonic cultivator who had lived for a hundred thousand years. But when he underwent tribulation, the heavenly lightning arrived a year early and struck him into a cripple, shattering even his primordial spirit! Worse still, his disciple Murong Shuang, whom he had raised with his own hands, had become an immortal. She came to his door to claim his pure yang physique, a treasure seen only once in a million years, and tormented him mercilessly. His fiercely loyal young disciple, Min Xiaobai, tried to protect him, but Murong Shuang brutally crippled her hand, nearly shattering her bones. Driven to the brink, Qin Jiu was forced to kneel before his enemy. His face swelled from slaps, and his dignity was trampled into the dirt. But no one knew that his pure yang physique concealed a world-shaking secret. Murong Shuang, you think you're so untouchable? Just wait! For today's humiliation, I'll repay you a hundredfold one day! You ungrateful wretch who betrayed your master, sooner or later I'll make you taste a fate worse than death! Qin Jiu clenched his fists. Even if he had only one breath left, he would reclaim everything he'd lost, twice over, and climb back to the top over your corpse!
