Elemental energy was nothing uncommon.
During the early Cultivation Era, it was heavily studied but not utilized as widely. Due to spiritual force’s more abundant and active nature, it was easier to use than elemental energy. In fact, the ample production of spiritual force suppressed the generation of elemental energy, and so the study of elemental energy was mostly limited to small sects.
It was only in the Wilderness where the spiritual force was thin that elemental energy could dominate.
It had to be said that the cultivation world was favored by nature, as if the heavens had blessed the people with abundant spiritual force that covered the land. For a long time, almost every cultivator held themselves upright with pride, assuming their cultivation world as the core of the world.
