Xiao Yi's Blood Slaughter Sword in his hand gently quivered.
In mid-air, a vortex of Spiritual Energy suddenly appeared.
It was more than ten times larger than the vortex condensed by the Netherworld Sky Sword.
"High Grade... High Grade Spiritual Artifact," Guu Changkong had a moment when he couldn't believe his own eyes.
Not just him, even his Guu Family and the major clans of Baiwu City only possessed Low Grade Spiritual Artifacts.
Even with the help of the Sword Hall Elders and obtaining the Starlight Stone,
they merely had a Netherworld Sky Sword that could only compare with a High Grade Spiritual Artifact.
What a real High Grade Spiritual Artifact represented and how terrifying it was, he knew all too well.
That was something even a Mystic Breakthrough Ninth Layer Martial Artist would covet.
At that moment, Xiao Yi casually pointed with his sword.
"Guu Changkong, do you still remember the score from over a year ago?"
