In the center of the palace, there was a carving of a sharp sword that seemed poised to pierce through the heavens, to break the skies asunder.
The next moment, the sword within the palace suddenly shot out. From atop the white jade-like palace, a beam of rainbow light burst forth, slashing across the sky as if a rainbow, and the void was instantly penetrated by this light.
Before the sword light even touched down, the lethal Sword Qi had already reached Cao Zhen's presence. The sharpness of the Sword Qi made Cao Zhen feel as though even the outermost layer of his Protective Divine Power would be pierced through without the Sword Qi actually landing on him.
This sword was sharp to the extreme.
Cao Zhen had fought many opponents, and among all those he had encountered, this strike was the sharpest!
Even Wu Jianzi, who practiced the Sword Dao and emphasized the sharpness of the first draw, had never delivered an attack as sharp as this!
