Sterl observed that after absorbing the soul energy, the soul puppets had indeed grown slightly in size. However, this increase wasn't a fundamental enhancement—it merely added ordinary soul volume to their existing high-tier Divine Authority-level quality souls.
"Forget it. If it doesn't work, it doesn't work," he muttered.
Sterl had initially hoped that using ordinary soul energy could directly enhance the fundamental capacity of the soul puppets. If successful, it would have allowed him to convert ordinary soul energy into high-level soul energy in a roundabout way.
But it was clear he had been overly optimistic.
This outcome made sense. Though both ordinary and high-level soul energy belonged to the same category, their essences were entirely different.
Even if ordinary soul energy could increase the total soul volume of the puppets, the conversion ratio would likely be so steep that it would hardly be worth the effort.
