Why Does It Sound Familiar?

Grey's body stopped giving off the oppressive energy and the chaos energy he used to cover up the origin source had successfully eaten a chunk of the origin source. The fact that something like that was even possible was beyond Grey's imagination. 

A bold thought came to pass and it was something that he never thought would've been possible. Now that he had eaten a chunk of the origin source, he noticed that there seemed to be a difference in his elements. Not just that, but there was something else, he could vaguely sense the existence of more than eight elements. The feeling was small, but he had this itch in his heart that there were more than eight elements. 

He didn't think too much about it, after all, all he had heard of was eight elements, and he had all eight of them. Even though a few of them were weaker, he was certain that he would be able to raise all of them to the peak elemental grade.
