The transformation of the Primordial Spirit Body was something Milton Cheney could distinctly perceive.
After all, it was considered an advancement of his Realm.
In the Primal Spirit Realm, the cultivation level is essentially the stage of the Spiritual Body's transformation.
In this respect, Primordials and Demons share similarities.
Once the transformation of the Primordial Spirit Body began, Milton Cheney could clearly feel his Spiritual Body continuously drawing energy from the Sea of Primordials.
The energy was vast, and Milton Cheney didn't need to actively extract it from the Sea of Primordials.
Rather, the energy from the Sea of Primordials ceaselessly surged towards Milton Cheney.
This sensation was extraordinarily comforting and completely different from the feeling during a Demon's transformation.
The transformation of a Primordial wasn't something that happened imperceptibly; instead, one could clearly sense the changes within their Spiritual Body.
