Laying a trap for Gu Daoyi

Yet Ling Han knew nothing of this. He was engrossed in formations, and completely had no knowledge of the passing of time in the outside world.

In the blink of an eye, two years had passed.

Ling Han suddenly moved, and opened his eyes underneath the Reincarnation Tree. He had completely grasped the Blood Crow Formation.

For formations below Saint-level, one only had to completely comprehend the formation patterns. But above that level, one would have to possess the power of construction. Without comprehension of that aspect, even if Saint-level formation patterns were inscribed on a formation eye and given to you, you would not be able to release its saintly might.

Just like how the power of a Saint Tool in the hands of an Eternal River Tier was limited to the peak stage of the pinnacle level, perhaps the power could reach Saint-level, but without corresponding power of Regulation, it could still not be claimed to be Saint-level power.
