Just like when Cain sent his Ego Wave into the starry gem that held Blood Hand, an illusion appeared in his mind, and he saw a man standing on top of an ocean full of blood.
What surprised Cain was the fact that the man was Bloodless #1. It seemed that the powerhouse was the one that engraved the technique into the starry gem.
For a moment, Cain wondered if he engraved his understanding of a Saint Technique in the future, whether people would see a picture of him going over the technique. Those thoughts did not last for long as soon his focus returned to Bloodless #1 as this one went over the Blood Refinement Art.
Bloodless #1 started from the beginning, devouring the blood beneath his feet and using it to nurture his flesh. Then came the formation of Blood Energy.
Those were the first and second levels of the Blood Refinement Art, something Cain knew very well, but the next part was completely new for him.
