As the battle progressed, David and Darren started to get a better understanding of each other. They familiarized themselves with the style and strength of their opponent.
After fighting for quite some time, David was finally able to recognize all of the artificial talents that Darren had. Most of those talents were auxiliary ones that could be more helpful in battle such as ocular talents and special body constitution.
The ocular talent that Darren possessed was similar to foresight which could read through the movements of his opponent and predict their next course of action. Aside from that, it also had the ability to see the invisible energy within the air which greatly countered most mentalism techniques.
