Hundred Flags of Void Sealing

Before the doubtful gazes of the three master teachers, the young man stared intently at the land below with the formation flags in his hand, seemingly calculating the positioning of the flags.

"Zhang shi intends to set up the Illusory Footsteps Beguilement Formation?"

Seeing his actions, the eyebrows of the three master teachers shot up in astonishment.

Putting aside how narrow the gorge was, just the battle below was sufficient to cause immense chaos in the spiritual energy in the air. Even with a compass in hand, it would be impossible for one to accurately read the flow of spiritual energy. As such, how could one possibly set up a formation?

Even if a 7-star formation master were to arrive on the scene, he would surely be unable to successfully set up a formation as well!
