Bab 457: The Third Power 

Vicente had two Magic Gems that both "lived" in the same space. If he wasn't careful in his meditation, he could accidentally absorb a pentagram compatible with one of his gems into the other, which would cause terrible problems.

Not only that but since the pentagram he was absorbing was of a higher quality than what was suitable for people of his stage, he had to go through a few phases of absorption to make sure that nothing bad would happen to him.

His current body was already much more prepared than when he had absorbed the yellow pentagram from his first gem. However, it still wasn't like a Sovereign's, which meant the green pentagram could kill him!

That was why Vicente had suffered so much in the past few hours!

However, he was no longer so fragile and was in a better condition than before. As he absorbed this essence, he had a better idea of what he needed to do and naturally acted to get the best result, something that took time.
