Xiao Yifeng's brows furrowed slightly, and his eyes flickered as he muttered to himself, "Absorbing blood for cultivation... what sect or power does this belong to? It seems Tianhai City hides quite a number of masters."
According to Xiao Yifeng's previous observations, the blood of the deceased had been completely drained, and the perpetrator was undoubtedly a Martial Path expert who specifically cultivated using human blood, hence why the victim's blood had been drained dry.
However, such a method of cultivation was extremely sinister, and it was unknown how long such an evil person had been hidden within Tianhai City.
After pondering for a moment, Xiao Yifeng decided not to concern himself with the matter any further. After all, as long as the person didn't cross him, everything was fine. Should they dare to provoke him, no matter who they were, they'd have only a dead end to face.
