Gu Feng's old face was stern, a cold glint flashed in his eyes, and he immediately controlled the Purple Flame Flying Dagger to shoot out, directly striking the formation barrier.
As he moved, the other twenty Foundation Establishment Cultivators also reacted quickly. Being well-trained, they all cast their specialized spells, attacking the seemingly fragile formation barrier with full force.
"Zzzzz…"
Dozens of spells, Spiritual Treasures, and Spiritual Artifacts landed simultaneously, Spirit Power converging, and light shining brightly.
However, the result stunned all the Zhao State Cultivators; every attack was repelled by the formation, without exception!
The entire formation was like an indestructible copper wall and iron barrier, still intact, without a single crack.
"What? It can't be broken?" The Crown Prince of Zhao's face instantly turned ugly, filled with disbelief.
