Before the Taoist Ancestor opened the way of Immortal Path, the cultivation systems in the Primordial Era were numerous.
Body Refining, Soul Condensation, Qi Refining, Blood Sacrifice, Harvest Supplementation, Dual Cultivation...
These cultivation systems were complex and chaotic, without a clear and complete division of realms.
It was not until Hong Jun Taoist Ancestor pioneered the Immortal Path cultivation method, focusing on Primordial Spirit cultivation, comprehending the great Dao of Heaven and Earth, and imparting this method to all species in the Primordial, that the Immortal Path became the mainstream cultivation system and also obtained a clear and complete division of realms.
Unfortunately, although Yu Yuan tried to practice the Immortal Path, with his initial step into it, he became a superior Profound Immortal, but then... there was no follow-up.
The more he practiced the way of the Immortal Path, the more his Dao Xing realm regressed.
