Chapter 154: Risa's Potential? (Bonus)

"Why did a vampire evolve from sucking my blood?"

When she heard that question, the fairy queen gave an answer as if she had read it in a book. "There are multiple reasons. First of all, do you know what the vampire sucks?"

"Blood."

"Then what does blood contain?"

"Hmm? Red blood cells, white blood cells, or something like that?" Nathan tilted his head in confusion. "I don't know a lot about biology."

The fairy queen shook her head. "Your blood is influenced by your Ena and your soul. If you are a being from another world, it will change your blood as well. And due to your unique Ena that can summon a beast, we know that your blood is different from other people."

"That is weird." Nathan thought for a moment. "If that's the case, why would the one who discovered me to have Ena in my body consider me to have a tremendous amount of Ena? Meanwhile, I only had 60 Ena when I summoned my first familiar."
