Thus, over the next few days, Duanmu Huai devoted his energy to researching the Human Magic System.
Although Duanmu Huai was not familiar with the Human Magic System itself, at its core, it was just another way of using Spiritual Energy. As a Judge, he understood the application of Spiritual Energy.
Therefore, all he needed was the theory of the Human Magic System.
However, it must be said that this theory was indeed extraordinary.
Humans can die, fire can be extinguished—such things anyone can imagine. But as intellectual beings, humans' imagination is conditional.
That is, rationality and instinct.
Take, for instance, the attack Frieren had previously launched against Duanmu Huai——she could certainly imagine the armor being penetrated, as anyone who has seen a similar scene could form such an impression.
But, rationality wouldn't have it that way. In Frieren's rational mind, she had already deemed Duanmu Huai's armor to be incredibly sturdy and hard to destroy.
