Although there is a subtle difference from spiritual energy, overall, there is nothing significantly different from it.
Moreover, Wang Yang only needed to absorb a little to determine that, even if what was being cultivated was not spiritual energy but the energy of this continent, the end result would still be the Power of a Saint.
This point truly could be described as reaching the same end by different means, no matter how the energy changes, it ultimately becomes the Power of a Saint.
For this reason, Wang Yang's Primordial Spirit continually absorbed the energy of the heaven and earth, and just before his landing on the ground, it condensed into a new body to carry his Primordial Spirit.
Looking at it, there seemed to be no difference from the Three Realms.
Wang Yang landed in a forested mountain area, took in the surroundings, the same lofty mountains and flowing rivers, the same towering trees, with plants and creatures all around indistinguishable from the Three Realms.
