The demonic thing clicked its tongue in admiration. Although this technique was completely different from the heavenly spell formation sect 's, it was not inferior in terms of the exquisiteness of the formation.
Combining two or more low-level formations to form a higher level formation was something unheard of.
The normal method of setting up a formation was to stack different formations of the same level together to form a stronger power, but combining them was something he had never heard of before.
If he could master this technique, his speed of setting up arrays would increase greatly. After all, the speed of setting up low-level arrays was not just one or two times faster than that of high-level arrays, but at least ten times or even dozens of times faster!
Setting up a high-level array with the technique of combining arrays and then stacking them on top of each other, the increase in speed and power was simply immeasurable.
