No wonder Ling Cang was so startled.
In the Cultivation Realm, as time passes and environments change, some spirit medicines go extinct, while new ones emerge.
All alchemists are aware of this.
Therefore, many Sects consider improving their inherited pill formulas.
This is to make the cost of refining elixirs within the Sect lower.
However, doing so is not easy.
Especially for a Sect like Jiuhua, where some inherited alchemy techniques have been partially lost for various reasons.
Improving a pill formula is by no means an easy task.
On one hand, it requires profound understanding and mastery of various spirit medicine attributes, fire control techniques, and pharmacological combinations.
This means only someone with very high alchemical skills can undertake such tasks.
Even then, such individuals can typically only improve pill formulas a few grades lower than their own alchemy skills.
For example, Ling Cang himself can now refine Advanced Middle Grade Elixirs.
