The First Chaos of the Nine Tribulations in the Upper Three Heavens

Sixth-grade Sword Saint!

This was the highest cultivation that Gu Duxing could expose now that he had concealed his cultivation. It was also the most unconcealable aura. Mo Tianji tailored it for Gu Duxing, deliberately allowing him to reveal a sharp edge.

Lan Yingyu fixed his eyes on him and saw that Gu Duxing was full of inner strength, and within each movement, there was sword intent. It was as though every hair of his contained a sharp sword aura.

It was also the charm of sixth or seventh-grade Sword Saints: The sword aura flowed like a river, the sword light shone like the Big Dipper stars.

Lan Yingyu was immensely shocked. He had tried to solicit Gu Duxing in the Middle Three Heavens solely because he saw his potential. Although Gu Duxing was already a Sword Emperor at that time, in Lan Yingyu's opinion, he just had a terrible potential.
