Bronze Resonance Qi
Ryu stood in silence for a long while. He was so stunned that he barely registered the evolution his body was undergoing once again.
This wasn't just a small change, it was game changing. In fact, this change, even without considering the other abilities his Spiritual Foundation might have, was enough to change everything.
Ryu obviously couldn't use Essence as it would pose the same problems that Chaos Qi did to him. Flaunting his use of it would be like lighting up a beam that told the world he was here. However, this restriction wasn't as daunting as it had been with his Chaos Qi, and that was because of the existence of Primordial Qi and its derivatives.
