Not That Simple

Kafan shrugged his shoulders. "Why wasn't that enough? The reason was very simple. The higher their cultivation realm, the more Dead Souls they needed. What is the number necessary to reach the Divinity Realm as a Soul Devil? I can't even imagine, but I'm certain just a few billion is far, far from enough. Just like that, our Universal Transition Organization's Death Energy continued to expand."

Kafan sighed and decided to finish the story. "In the end, it took a total of three hundred and forty-three thousand years for our Death Energy to cover this entire side of the Universe. Our Divinity Realm Death Spirits of that time were dispatched to get rid of the Space-Time Realm Devils who, in the end, couldn't get enough Dead Souls to reach the Divinity Realm."
