From the Start, I Used the Twin Full Hands to Change the Demon Cult Leader's Sex

My name is Li Ailian, though people call me “Jade-Faced Green Lotus.” Everyone in the martial world says I can bring the dead back to life and restore flesh to bare bones. Truth is, I'm just a doctor who charges a little too much and has pretty good skills. Then one day, the leader of the Demon Cult came to my door on a stretcher, claiming his yang energy was about to burst out of him and begging me to save his life. He (roaring): “You can kill me, but you can't humiliate me! I'd rather die than become a woman!” Me (calmly): “Fine. Then I'll get ready to bury you.” Him: “...Do it.” I used every ounce of my strength to remake him from the inside out, turning him from a man into a woman, from a brawny man into an unparalleled beauty. I gave him a flawless body of pure yin with limitless potential, and threw in an incomparable beauty for free. He gave me fifty thousand taels of gold, and even threw in a brand-new clinic. By any measure, I got the worse end of the deal, right? As for that future demoness... Oh, she's still in my clinic, waiting to have her bandages taken off.
