Time trickled by. Chen Yao's Primordial Spirit steadily grew stronger. His realm remained unchanged, but his reserves kept deepening. Once he returned to his main body with his Demon Incarnation and synchronized their Primordial Spirit power, the benefits would be boundless.
The Ten Fiends possessed Immortal King bodies at the True Immortal realm. At the pinnacle of immortality, cultivating a king's body and a king-level Primordial Spirit before reaching the Immortal King Realm both helped their potential surge and their cultivation soar when they advanced.
Although he could not feel the pressure Shi Hao had experienced, with time passing so rapidly that it nearly drove him mad, Chen Yao still dared not relax too much. After testing the cage and finding that he could not exploit the power of the dark demonic blood to escape, he devoted himself fully to cultivation.
Chen Yao felt as though he had sat there for a year.
He devoted almost all his energy to drawing soul power from the void, striving to raise the strength of his Primordial Spirit.
Hard work rewarded the determined. Like a fish in water, he successfully raised his Primordial Spirit's strength to the Void Dao level.
He also sensed that the Dark Cage's restraint on him had reached its limit.
As he set his Demon Incarnation in motion, Primordial Spirit power far beyond his current limits erupted, enough to make gods blanch. Even sect masters of the Void Dao Realm could not take an attack from his Primordial Spirit power completely unguarded.
The benefit of cultivating a Yang God was that every aspect of his Dao Foundation could manifest through any of his incarnations. His Demon Incarnation, in particular, was an important component of his own power, practically an external avatar, and had inherited almost all his abilities.
