Sterl felt both surprised and delighted. This was the first time he had absorbed and refined a soul so smoothly, without encountering any resistance throughout the entire process.
It's important to note that while the Soul Devourer Sphere's effects were terrifyingly powerful, the backlash it caused could be a deadly disaster. Every time he absorbed and refined a soul, it was a test for his own soul.
This was especially true when refining the souls of powerful beings, as the backlash could even cause him to fail in the most straightforward situations.
But now, it seemed that Sterl had found a far more perfect method for refining!
That method was to first wipe out the enemy's soul and will using the Soul Prison's Eerie Eyes ability, turning them into his puppets, and then proceed with the refinement. This way, even when refining the soul of a higher-level divine authority, no backlash would occur!
