Now that Michael knew what he had to do to increase his combat prowess rapidly, he could focus on studying the Tekur's memories and alter the wide variety of Soul Techniques he'd procure. In fact, Michael was pretty sure that he could experiment a lot and create a new series of Soul Techniques. These techniques wouldn't be on par with Common Class Soul Techniques right off the bat, but that was something he could work on.

Michael's pupils were now entirely silver, creating a stark contrast to his vibrant golden irises. Upgrading Spirit Gaze didn't stimulate an evolution. It didn't hurt that much either. Michael could easily endure the pain.
