Once the gray flames had fully flooded the body of the member of the Dark Brotherhood, the Eye of Gluttony began to tremble before unleashing an immense devouring power that drew the gray flames.
Cain could feel a much higher devouring efficiency using the Soul Devourer Legendary Cultivation Technique. The Eye of Gluttony consumed the life force, vitality, energy, and Spirit Force, leaving nothing left.
It did not take long for a halo of gray flames containing a massive amount of energy and vitality to appear around Cain's energy pool, brimming with power that he could use later to replenish his reserves or, more importantly, advance in the crystallization process.
Cain was exhilarated by the devouring power he now possessed, a sensation that escalated to pure and absolute bliss as he witnessed a stream of golden force being carefully extracted from the energy pool and merging with his own.
