Yang Fei couldn't help but take a deep breath.
This White Bone Longsword was imbued with countless True Martial Divine Arts of Yang Fei and further tempered by Phoenix Mysterious Fire.
It can be said that even a tank's alloy steel plate cannot withstand the slash of the White Bone Longsword.
However, the body of the Nine Child Sky Demons is even harder than alloy steel plate.
If caught by the claws of the Heavenly Demon, even an iron man would be torn to pieces.
In the blink of an eye, the White Bone Longsword and the Nine Child Sky Demons had clashed hundreds of thousands of times, with countless sparks flying.
The Nine Child Sky Demons appear and disappear unpredictably, as if following some kind of formation among the nine demons.
Yet, even so, they cannot break through Yang Fei's Thousand Extremes Sword Formation.
Zhou Gongzhi, standing by, greatly restrained his arrogant demeanor.
