"Whoosh!"

Without needing to draw upon the heavenly and earthly energies, the Chixuan Sword was swung using only the power of the Hidden Vein, unleashing a strike of Gang Qi!

In the face of Gu Yifei's massive Gang Qi, Su Mu's Gang Qi seemed pitifully small, lacking any apparent destructive power.

The onlookers frowned, many secretly shaking their heads. How could such an attack possibly contend with Gu Yifei?
