For the first time preparing medicine on my own, my hands and feet were inevitably a bit clumsy, but following the methods and steps from the "Shennong Scripture," I still managed to look the part.
Having studied the pharmaceutical chapter of the "Shennong Scripture," I knew that alchemy was divided into three tiers.
The lowest tier was the preparation of relatively inferior medicines.
Next came preparing mid-tier medicines, which required mastering the heat. Otherwise, it was easy to waste all previous efforts.
The most difficult was preparing high-end medicines, which reportedly required the use of the Three Mystic Fires.
Luo Yang didn't know what the Three Mystic Fires were, though it seemed there was a time when he had understood such matters, but he could no longer remember.
The Master Servant Pill belonged to the lower-middle tier of medicines; a slight deviation in heat could still lead to a successful concoction.
