After a simple introduction from Cofuran, Yuchi gained a general understanding of the Alchemist Valley.
In general, the reason why the living beings here were so good at alchemy was due to the sun and environment here. Various kinds of herbs grew in the valley, and the living beings here had learned to use and refine these in order to survive.
Although these living beings were not cultivators, the effects of their medicinal pills were dazzling. If they really fought, their actual combat strength would be similar to Dao heart realm cultivators.
In a sense, one could say that they consumed medicinal pills to increase the strength of their physical bodies to an absurd level. These pills had both permanent and temporary effects.
It was just that they had no way to make use of the Heavenly Dao. Otherwise, their strength would be even more terrifying.
