The moment Rui bore witness to the chimera at the start of the battle, countless tactics and strategies emerged within the depths of his tremendous mind.
Yet, the most important among them was centered around chimera's mind.
More importantly, its SOUL.
It was the creature's greatest weakness. The greatest weakness of the entire species. The lag between decision and action in the chimera was twice as large as it normally was.
This was because, unlike normal creatures, action did not immediately follow the decision to act. The brain of the chimera was not directly connected to most of its body. Once it made a decision, it then indirectly manipulated the minds of the angel, phoenix, and dragon to make the decision that it wanted, and only then could it move its body.
