章 1912: The core area _1

The arrangement of runic magic circles started from the simplest, but the more one went on, the more difficult it became.

Runic magic circles of different grades had different levels of difficulty in setting up and required different materials.

It could be said that Tang Zhen had put in a lot of effort in order to set up this trap. Otherwise, he would not be able to complete the plan.

In fact, this was very normal. The operation of each demon tide consumed a large amount of resources and time. How could it be possible to disguise it in a short time without spending a lot of money?

If he thought of using the illusory formation to fool the evil demons, he would be looking down on them too much. They were not weak to that extent.

As long as the evil demons were slightly stronger, they would be able to see through this kind of illusory array. It must be known that they were the real experts in fooling and deceiving.
