"No! Damn..." Hex Yuankui's face turned frantic, cursing through clenched teeth. His pupils quickly filled with a black force, giving a feeling of eerie coldness, like Yin Qi buried underground for many years.
That was Mystic Yin Qi, though not complete, it was still quite rare at the Qi Refining Realm. Thus, Hex Yuankui was stronger than ordinary cultivators of the same rank.
The Mystic Yin Qi surged wildly, flooding his arm and fist, then blasted out like a mortar shell! It fiercely collided with the fist of Blue Whale.
Boom!
The azure-colored Demon Qi and the black Mystic Yin Qi seemed to freeze mid-air at that moment, but seconds later, the black Mystic Yin Qi was shattered like a breaking bamboo!
"Not bad strength, but unfortunately, if you want to face me head-on, you are far off."
