It was easy for a Grandmaster to set up an array.
The higher the cultivation.
The difficulty of setting up the formation was lower.
However ...
Setting up a formation also depended on the situation. It was not an easy task to set up a large formation that was millions of miles long and needed to block the spiritual energy of a continent.
"In addition, the formation can't have any flaws."
"Even if cultivators fought, the shockwaves wouldn't be able to destroy the formation."
"In that case, we'll need the array base."
Qin shujian thought to himself.
With his current means, it was not a big problem to set up a formation in the void.
It was still the same sentence.
In order for the formation to be powerful enough, it needed a formation base.
"If I use the void as the formation base, it won't be powerful enough. Unless I can create a small world, I'll still need to use external objects."
Qin shujian thought about this.
