Chapter 607: Blood Exchange

---

"I never thought I would have to use this again, but here we are." Raven's face was somber as he held the Brush of Wisdom tightly. 

He looked up and released a long sigh before moving his hand. He raised the Brush of Wisdom bit his tongue and spat out a glob of his blood essence. 

The glob of blood essence flew towards the brush, dyeing the tip red. Raven paled considerably because of that but the glint on his eyes remained. He supplied even more Cosmic Energy on the Brush of Wisdom causing it to release a brilliant red light. 

'And here I thought I would never have to use this technique again. Well, it isn't so bad I guess. I could always recover my losses anyway.' Raven muttered inwardly as he witnessed the red flash of light getting more and more brilliant as time went on.
