So-called sword qi can be simply understood as processed yuan qi. Heaven and Earth Spiritual Energy is absorbed by sword cultivators, forming a special kind of Yuan Power inside their bodies.
The same goes for saber qi, spear radiance, saber intent, and so on; they are all fundamentally the same.
Sword intent, much like saber intent and other similar manifestations, is another outward expression of a cultivator's willpower.
