Taking Another Person Into The Chaos Space

"You broke through… took you long enough." Lucas commented when Grey walked out of the cave. 

He sensed it the second Grey broke through. While Grey was fighting with Klaus and the others, he sensed that Grey would've been able to break through while fighting, but he stopped himself on multiple occasions. 

The intensity of the battle was exactly what Grey wanted to hone his cores. Grey continued honing his cores as the battle intensified. After a few more times, he knew he was ready to finally break through to the next stage. 

He took a glance at his father and smiled softly, before nodding. His experience has been one of surprise. If he was told ten years ago that he would be where he is at the moment, he would never have believed it. From a regular person, to a Ninth stage Elemental Venerable.
