"Soul ring? Martial soul?"
Having seen the Clear Sky Hammer before, Tian Hao quickly understood what was going on.
It turned out that not only had Shi Nian's consciousness and Mental Power attached themselves to the soul bone, but even his martial soul had been brought in. This was likely due to the special nature of Shi Nian's martial soul. The remaining half of his soul had also scattered apart and been instinctively absorbed by the martial soul to sustain its existence.
"No, it's not that simple."
His gaze fell upon the outermost black Ten Thousand Year Soul Beast ring. Tian Hao sensed that the Soul Power aura on it was identical to the Soul Power aura within the Illusionary Soul Bone he had refined. They clearly came from the same source.
"Did they come from the same soul beast?"
Deep in thought, Tian Hao felt that Shi Nian's head soul bone must have been a lucky drop obtained when he killed a soul beast for its soul ring.
Soul Masters generally killed soul beasts to obtain soul rings. Few would slaughter large numbers of soul beasts solely for soul bones.
The main reason was that soul bones had an extremely low drop rate. Aside from Hundred-Thousand-Year Soul Beasts, which were guaranteed to yield soul bones, other soul beasts might not possess one even if they had reached ninety thousand years of cultivation.
Furthermore, soul bones were not indestructible. Soul ring skills of the same level could damage them. Tang San's Eight Spider Lances had been shattered several times.
Thus, even after so many years, there still were not many soul bones in the world—at least, not many out in the open.
Therefore, most soul bones possessed by Soul Masters without the backing of major powers came from soul beasts
