To advance in rank, cultivators had to make immense efforts.
Moreover, the spiritual energy in the vast world had depleted to a maddening degree.
If the villagers practiced the Immeasurable Sword Art without the aid of spirit grass, it was very likely that they would never advance in their lifetimes.

Spirit roots and the martial veins needed to become a martial artist were different.
Whether a person had a spirit root was determined at birth.
