But Samuel knew what this is.
It was one of the few techniques that rune master often used, called disappearing formation. But this technique could not be used often because it interfere with the mana flow in normal formation.
So this kind of formation would only be used in some special formation.
Samuel didn't expect Riya could use it so easily like this, though.
"Do you not want them to know there's a formation here at all?" Samuel asked.
"I figured it'll be troublesome if they found out that there's a formation here," Riya replied calmly. "Besides, the disappearing technique would not hinder the performance of this formation."
She has confidence in her formation.
Samuel heard this and nodded. "That's good."
Riya smiled and then put down the bucket containing the magic beast's blood that she used to draw the formation. While it might be better to use bottle, but for a large scale formation like this, the among of magic beast's blood that she has to use was enormous.
