The 16.0 realm was the Rebirth Realm, the classification level for Big Data Cultivation.
The corresponding realms for other cultivation paths were:
Faith cultivation: Ignite Divine Fire, officially becoming a deity;
Immortal Cultivators: Void Refinement, fully known as "Refining the Spirit and Returning to Void," commonly called "Earth Immortal," having already transcended the concept of "human";
Mages: Ignite Divine Fire, officially becoming a god of magic; but this divine fire seemed to be some kind of tiny spiritual flame, somewhat like an Immortal Cultivator's primordial spirit. In any case, Chu Fei had never seen a level 16.0 mage;

Martial Dao: Return to Truth, but no one knew exactly how one returned to truth, because Chu Fei had never seen a Martial Dao expert at this realm either.
The other cultivation paths did not even possess theories concerning 16.0.

However, immortal cultivation had high requirements for talent, while Big Data Cultivation required an enormous foundation
