Alchemy, Artifact Refining, Array Creation, and Talisman Making are the Four Great Skills of Cultivation.
Why are they called the Four Great Skills?
On one hand, these skills are extremely broad in scope. Any cultivator, without exception, frequently encounters them in their practice.
On the other hand, if a cultivator masters any one of them to a relatively profound level, they can earn resources through the skill, supporting their cultivation.
Even if they haven't dedicated specific time and energy to study and explore them, as cultivators age, they naturally accumulate considerable experience in these four skills.
The reason for this is simple—living long means more interactions with the Four Great Skills, naturally enhancing understanding in these areas.
