Insatiable Desire
Ryu's Phoenix Bloodline was a bit weirder and more difficult to pinpoint, and this was because there wasn't a direct one to one comparison he could find anywhere. As such, it was impossible for him to make calculations or even guesses.
At best, he knew that the individual pieces that made up the fused Bloodline were also considered to be at the First Origin Grade. As for what they were when they came together, he didn't know.
When it came to Ryu's Bone Structure, it had mutated and taken a half-step beyond the Ancestral Grade and was considered to be a Quasi-Origin Grade talent.
Then there were Ryu's Meridians. He was absolutely certain that they were not only Origin Grade, but very high up in Grade. The trouble was that their strength was contingent upon a very unique cultivation method, a method that Ryu simply didn't have.
