Alchemy requires talent, but more importantly, countless repetitive alchemy practices.
What is the Dao of Alchemy?
Adept can create skill, skill can create precision, precision can create magic, which can lead to enlightenment.
Alchemy, thus, is the direct embodiment of talent and proficiency.
Having talent alone, without putting effort, is nothing more than an empty title with no essence, hence, hardly notable.
What if there's only effort without talent?
That will only lead one further astray on the wrong path.
This principle is not limited only to the Dao of Alchemy.
It applies to most of A Hundred Arts of Immortal Cultivation.
Enough digression.
In the career of a Pill Refiner, countless experiences in refining pills are necessary to become a high-grade pill refiner.
But the potential of a single person is extremely limited.
