A god-level alchemist, starting by manually crafting forbidden pills.

While others refine pills, I make them by hand. But what they don't know is that there's something wrong with the pills I make.
My senior sister took my top-grade Lesser Rejuvenation Pill, and that very night, she was embraced by a warm and soft body.
My junior sister took my Tiger Strength Bone Pill and was forced to comprehend the Ten-Person Godhood Domain. She chased after me calling me "husband."
Elder Qian took my Tranquilizing Pill and immediately awakened his Eye of Truth. He publicly criticized the sect leader's fake makeup and was chased down across eight mountains.
Even the Golden Core demonic cultivators who were chasing me cried out for me as their master after detonating my Exploding Core.
Until the sect leader was seriously injured and needed the Nine-Turn Soul-Condensing Pill to prolong his life.
In the face of utter despair, I silently took out a batch of pills radiating five-colored light.
"Um... this pill was refined a bit too aggressively, and the side effects can only be countered by dual cultivation with me."
"Sect Leader, will you choose to take drugs, or will you choose me?"
The sect leader looked at the pills, then at me, and smiled sweetly, "I want both."
