This time, Leonel wouldn't be leaving even a single one of his brothers behind. He had already decided that even if he had to carry them up the steps one by one, putting them on his back, he would do so.
Leonel didn't actually believe that his brothers were untalented. Among them, there were several geniuses.
Arnold was a genius of Universal Force. He had mastered higher levels long before Leonel did, and the only difference between the two of them was that Arnold had gone off on a wrong path because of a lack of guidance, while Leonel had been lucky to unlock it during his battle with Lionel.
Back then, Arnold didn't know that you could have a ubiquitous form of Universal Force because no one talked about it. As such, he always focused his Universal Force on his palms until Leonel taught him that another route could be taken. It was only after that that he managed to start following the right path.
