I'm Raising the Villain's Genius, Beautiful Disciple

At death's door, I jolted upright, then slept for thirty thousand years.

The primordial demon Shen Cang awoke once more and looked at the beautiful girl he'd nearly drained dry.

"Young lady, you have the bearing of an immortal!"

The girl swore at him: "Have you ever heard the legend of the third stage of Qi Refining?!"

Shen Cang thought for a moment, then held out a hand. "Then how about becoming my disciple?"

"I, Shen Cang, pioneer of the Heavenly Court's great upheaval, guide to the monsters' path, and destroyer of the Heavenly Pillar, once charged from the Southern Heavenly Gate to the Northern Heavenly Gate with two watermelon knives in hand and my disciple at my side, without so much as blinking. What's wrong with taking in a pretty young disciple and enjoying myself now? Keep the music playing and the dancing going!"
