Nourishment Pond Formula

"Father, you probably knew a few things about Hosts. Currently, I need a Nourishment Pond formula. Do you know anything about this?" 

Merlin did not expect Count Stanwin to have the Nourishment Pond formula. After all, this was the lifeline of every Host, so they certainly would not reveal it easily. Seeing how eager Heroult was to bring Merlin along with him and use him as a test subject, it showed how important this Nourishment Pond was. 

Without a Nourishment Pond, the Hosts were completely unable to level-up and cannot enhance their abilities. This meant that they were forever inferior to those who possessed the almighty beast bloodline. Therefore, a true Host must have his own Nourishment Pond. 

"Nourishment Pond? Of course, I've heard of it. The most important element for every Host is the Nourishment Pond. An almighty beast's will and a Nourishment Pond – those two are essentials for every Host."
