"Ha… finally, it's all refined."
The backlash from the soul's impact came to a sudden stop. Sterl let out a long breath, but the aftereffects of his soul's damage didn't disappear. His brain throbbed with sharp pain, his vision blurred, and his mind felt unusually fatigued.
"The soul resilience of an Upper God is far beyond that of a regular god. The difficulty of refining their soul is at least ten times greater. If I plan to absorb and refine the soul of another Upper God in the future, I'll need to ensure absolute safety."
He shook his head slightly, trying to ease the weakness that had settled in his spirit and soul.
Had someone attempted to strike him down while he was refining the Silver Moon Wolf God's soul just now, not only would he have had no strength to resist, but his mental will might have become unstable, causing his soul to fluctuate and lead to even greater damage.
