The Divine Pill did not first appear in Swamp Prefecture but in another prefecture—Nanyan Prefecture. This Nanyan Prefecture is adjacent to the Pyu Kingdom and has many strange animals and plants. Lingnan has many peculiar things, but there are also very effective medicines made from the plants and animals here.
In the Western Regions, there are many forbidden drug ingredients, which are said to also originate from here. Most of the materials in the forbidden drugs from the Pyu Kingdom and Annan also come from here.
Here, there are also many poisonous insects, snakes, and ants, among other animals. The poisons from Lingnan are renowned across the world because there are many poisons here that people have never heard of. Moreover, the toxicity of these poisons is quite terrifying; once poisoned, one is almost certainly doomed, as there is no antidote.
