Negotiation

"As long as you put the magic cores inside the four formations, it would connect automatically." Riya chuckled. "Their design made sure that even if there's some distance from the other formation, it could still be connected as long as the mana can be transported between them."

And this was another weakness of this formation.

Because if the mana was cut off through one way or another, the formation would fail.

Thinking about this, Riya quickly said about it to Samuel.

Samuel nodded and then asked, "What about the price?"

This is a trade, so it was necessary to put up the price first. 

Riya thought for a moment about this.

The formation required to make this formation actually encompassed several types of formation. It was another question whether they could make it or not after she passed the method over to them. 

"10,000 rank 4 magic cores or a hundred times rank 3 magic cores," Riya replied. 

1,000,000 rank 3 magic cores.
