Xu Zitao's eyes turned savage, and his entire aura became extremely violent.
Even the Pill Essence circulating around him began to glow with a somewhat sinister light.
His originally pure Pill Essence had turned a foreboding, dark color. The sight sent an inexplicable wave of fear through the Cultivators from the various sects.
"What kind of power is this?" Many people watched in confusion.
The Pill Essence, once as pure as water, was now as dark and sinister as ink. No matter how one looked at it, it felt somewhat evil.
Dark patterns even swirled around him, looking as if they were about to form fish scales and attach themselves to Xu Zitao's body.
As this Blood Qi was activated, Xu Zitao's aura also grew incomparably powerful.
Ling Fei remained calm, simply staring at Xu Zitao before him.
"Ling Fei, watch my sword!" At that moment, Xu Zitao's Spirit Sword moved, and the sinister Pill Essence from his body surged out like a great river.
SWISH!
