If I Torture Myself Hard Enough, Even the Male Lead Has to Call Me Dad

I was reincarnated as the doomed illegitimate son of a villain in a fantasy novel.

I got bound to a "Heaven Rewards Hard Work" System: as long as I work hard, I'll be rewarded.

So I started working insanely hard: breaking my own bones, burning my flesh, and drinking poison like water.

System notification: "Self-harm ongoing. Infamy +1. Limb regeneration progress: 97%..."

At last, the day the male lead came to kill me arrived. My whole body was rotting, yet I smiled like a demon.

"Have you mastered the technique?" The male lead's sword tip pressed against my throat.

"No." I licked my rotten lips. "I just learned how to make you experience it too."

That night, amid the screams of the city's cultivators, the male lead looked at his own hand as it began to rot, and finally showed fear.

"Welcome aboard," I said, looking down at him on his knees. "This wonderful game of hard work."
