Black Feather Grass, a top-grade spiritual medicine.
It only grows on the body of the Yuan Ming Mountain, maturing by absorbing endless dark energy.
The growth period of this Black Feather Grass is extremely lengthy, requiring two thousand years to mature.
The primary function of Black Feather Grass is to use the endless dark energy to achieve Dark Divine Power.
Although the Black Feather Grass also contains some of nature's spiritual energy, it is only a small amount compared to the dark energy.
However, for Chen Yuan, that portion of nature's spiritual energy was already sufficient.
The True Sun Fire refined from the Nine Yang Fruit within his body was still half remaining, and together with the nature's spiritual energy contained in the Black Feather Grass, it should be enough for him to break through to the Condensing Stage.
Moreover, he could also cultivate the Divine Skills contained within the Black Feather Grass.
