Medicines in the world of Immortal Cultivation are broadly classified in much the same way as those on the Douqi Continent. There are healing medicines, supplementary ones, breakthrough aids, strength-enhancers, and unorthodox concoctions as well. Yet the medicines of the immortal cultivation world are far more complex and diverse than those of the Douqi Continent.
Take, for instance, the Demon-Slaying Pill, specifically used to combat inner demons, which does not exist on the Douqi Continent. Neither are there the Nine-Turn Golden Pill, the Nine-Turn Great Restoration Pill, the Taiyi Immortal Pill, and other elixirs capable of elevating ordinary mortals to immortality.
Of course, Gu Changqing did not possess them either, but he knew how they were refined.
