The dark figure was deeply troubled.

He had lingered at the pinnacle of the ninth-tier for endless ages, unable to advance further due to his failure to comprehend 'supreme substances.' This made him extremely eager for the void demon blood of the Source Realm.

Yet, whenever he thought of Courtyard Master Bei Yun, a trace of fear involuntarily surfaced in the depths of his heart.

"Damn Master Peng Hu, if he had just handed over that demon blood back then, none of this would have happened," the dark figure's expression was grim.
