Only He

Ryu's mind was churning wildly, quickly making deductions and then tossing them away.

He, of course, didn't think that the Phoenix Sky God did this out of kindness, that was asinine. If he died or was ruined prematurely, how could he be of use to this God amongst Dao Gods?

Ryu didn't know why the Phoenix Sky God wanted him to have this Spiritual Foundation, but what was a fact was that he wouldn't have been able to form it in the first place if he didn't piece together the Phoenix Sky God's story, and he wouldn't have been able to piece the Phoenix Sky God's story without great comprehension skills, great comprehension skills he had in large part due to his Heavenly Pupils.

Ryu's baseline of comprehension ability was high, that was how he had managed to form a Founding Dao even with his eyes sealed. However, with his eyes, he was on another level entirely, one that put shame to the greatest minds to maybe ever exist.
