According to some information he knew, the Immortal Realm was only established after the primordial era. Before the primordial era, that was the era ruled by the Fiendcelestials.
In the primordial era, before the first immortal appeared, humans were all vassals of the Primordial Fiendcelestial. They learned from the Fiendcelestial and cultivated the Dao of the Fiendcelestial.
Ever since someone established the Immortal Path and found the most suitable path for the human race, immortals appeared one after another.
Most immortals relied on external objects. Their strength was much weaker than the Primordial Fiendcelestials, but as the number increased, their status gradually increased and they occupied more territory.
