Chapter 154: King of Beasts

Castiel glanced up at the beautiful sky, seemingly lost in some thought. 

"There is still some time..."

He snapped his fingers, instantaneously casting a spell. A formation circle appeared under his feet. 

"Little one, you need to learn how to use these spells. Without them, you can never catch up to your opponents."

As the formation circle started gathering energy from the nature, Castiel didn't forget to remind Atlas once again of the importance of the spells. 

Every Progenitor had a special advantage, and being able to use spells was the advantage of Castiel, and it was supposed to be one of the best. These spells and his vast knowledge were what made him so strong throughout the years.
