Xia Wuji's words made Li Su and Zhu Jing's expressions turn solemn.
The chill of anger surfaced on Li Su's face after his sword strike had failed just now. He said, "Xia Wuji, what you just said is rather ungrateful."
"I've been in Azure Star Academy for a year, and I'm now at the ninth level of the Primal Energy Realm. Moreover, in an environment like Azure Star Academy, every aspect of my abilities has improved tremendously."
"Especially my swordsmanship!"
"Next, I'll show you just how formidable a low-grade Profound-tier sword art from Azure Star Academy is. I hope you'll gain something from my swordsmanship, so that my painstaking efforts won't be in vain!"
As he spoke, Li Su's sword technique rose again.
Whoosh!
A sheet of sword light instantly spread from the edge of his sword.
The sword light was actually vibrating violently, carrying tremendous destructive power.
This was a low-grade Profound-tier sword art known as Vibrating Light Swordplay.
Li Su's mastery of this sword art had already reached the Minor Achievement stage.
Facing the sheet of sword light erupting from Li Su, Xia Wuji remained indifferent. He swept up his sword and unleashed the Shadowfall Sword Art he had practiced in the courtyard just now.
Dense sword shadows burst forth, directly tearing apart the vibrating sword light.
Li Su gave a low shout and strode forward. The spirit sword in his hand swept horizontally toward Xia Wuji's abdomen.
If this sword struck him, slicing open the flesh of his abdomen would be the least of his worries. The unique vibrating force of Vibrating Light Swordplay would surge into its target's dantian.
Damage to the dantian was something no martial artist could recover from in a short time.
Xia Wuji now had a clearer judgment of Li Su's objective.
