After discussing the Genetic powers of his Chaos Level Genes with his daughter, he spent the next four days mastering it. He focused on training his genetic power and learned to utilize it.
Genetic power creates a unique aura that is genetic energy. This energy can be used to manipulate and control technology. Brian had never controlled technology utilizing this sort of energy.
But, he was quick enough to learn the basics since he has been dealing with techs his entire life. To create any tech, he needed enough knowledge about it, and using his powers now, he could transform them in any way he wanted.
For now, he is simply learning to generate and utilize the aura. Not to mention using Secret Gene Art, he can't even generate aura.
He can't do much with his abilities until he grasps the basics of generating aura. But, there was something that he found. The aura generated from the gene relies on stamina.
