These hands aren't only good at fingering!
"I intend to extract the Primordial Yin Qi from your legs and veins and open your spiritual meridians using acupuncture. I know of different methods to cure you. However, all of them need materials that aren't present in the empire, don't exist in markets, are too hard for my subordinates and me to find in the wild, or are worth so much that this husband of yours isn't rich enough to purchase. Moreover, as your illness can erupt anytime in the future, I don't want to wait anymore before curing you. So I can only wrong you and resort to poking you with needles. I will try to be gentle. It won't hurt much that I can promise. But things can go beyond my control during the treatment, and an unexpected situation can occur. So if you feel the pain is unbearable, grit your teeth and try to endure it. I will finish it as fast as I can."
