To break through the Sky Apex Realm, one must experience the Heavenly Earth Energy Baptism. For ordinary people, it is simply the Heavenly Earth Energy entering their body. However, for genius warriors, the Heavenly Earth Energy Baptism they trigger is much more powerful than that of ordinary people.
Exceptional geniuses have the chance to trigger a Dual Baptism, a feat extremely rare and seldom seen throughout history. Xu Ruoyan was such an example, as she had experienced a Dual Baptism during her breakthrough.
The Four Saints Enlightenment is even rarer. Throughout the vast river of history, no one has ever witnessed it; its occurrences are documented only in historical records.
However, Ling Chen's breakthrough was now triggering the heavenly phenomenon of the Four Saints Enlightenment, a remarkable sight that occurs perhaps once in a millennium.
