Actually, the Heavenly Devil Lord knew full well that the Blood Demon was no ordinary figure. Hundreds of years ago, he had already been a notorious devil of his generation. But over the past century, he had kept a low profile, stayed out of sect affairs, and focused all his attention on breaking through to the Nascent Soul Mid-tier.
Whether or not he had already succeeded in reaching the Nascent Soul Mid-tier, the terrifying Blood Sha Divine Skill he wielded could not be ignored.
The Blood Sha Divine Skill was a variant of the Great Yin Sha Technique, a divine skill of immeasurable power. Yet even within the Yin Sha Sect, few chose to cultivate it. The reason was simple: though powerful, it required practitioners to constantly absorb Blood Sha and alter their physique, even the very structure of their bodies. Blood Sha itself had an exceptionally sinister origin. Unlike Yin Sha or Yang Sha, which formed naturally between heaven and earth, Blood Sha came from blood pools. These pools required the blood and Living Souls of countless humans, refined through an array until resentment and blood energy intertwined, forming wisps of Blood Sha that surged with resentment.
