Chu Yuan left.
He left without a sound, carefree as the wind.
As for Zhang Han.
He was standing at the entrance of the hall in a daze.
Of course, he had no doubt about what his Respected Master had said.
It was just that the words had left him with a profound sense of shock.
No need for formation materials.
A single thought draws upon the forces of heaven and earth to form the array...
Is that really possible?
You should know that in the Cultivation Realm, formations always require the prior gathering of materials.
Powerful formations even need one to refine Array Diagrams in advance, infuse them, repeatedly practice the formations, and then they can be successfully set up.
To successfully establish a formation is incredibly difficult.
Therefore, when facing an enemy, no one would foolishly stand there waiting half a day for someone else to complete their formation before fighting.
The Array Master's shortcoming was just laying there.
