Marcellus' Breakthrough!!
After Aether left to go back to train, Marcellus pulled out the last he had of Arthur's blood and sat in the lotus position on the ground!
Marcellus drank the blood and his consciousness immediately went into his Lifeblood Heart!
He could see the golden blood fall and drip into the otherwise red sea of blood! After it fell, Marcellus' body lit up into his demon form and covered himself with lightning!
However, it was fading in and out of existence because of {Skill: Dark Rulers Meditation}!
At this point, the filled up mass of energy that was his lifeblood heart would have been drawing all the impurities from his body to it, the energy looks like a tasty meal for the impurities, you could say!
However, there were no impurities, so the only thing that ended up rushing towards his lifeblood heart was the waves of energy that had replaced all of his impurities!
