Sightless Eyes
The improvement was more than Ryu was expecting, or maybe he was only so surprised because he had underestimated his Bloodlines too much to begin with. As he had said previously, his Bloodlines couldn't be considered to be in balance, it was far more accurate to say that they tolerated one another, almost like an unorganized bundle of items forced into a small box. They ended up entangled like long wires, and it became difficult to extricate the power they should have had individually.
In reality, Ryu should have long since guessed that this was the case.
Back when he began his Body Realm cultivation, he had already known what he should have been able to expect from his Bloodlines. At the start of his journey, his Phoenix Blood should have given him 1000 jin of strength each while his Dragon and Qilin Bloodlines should have given him 2000 jin of strength each, this was the benefit of having Ancestral Grade Bloodlines in Sacrum.
