"That black blood... You can only use it once, right? It was basically just a special sort of blood with a high amount of mana placed into it so that you can still control it from further away, but now, all the mana was used up." Eiro guessed, and the woman slowly opened her eyes wide in shock.
"How do you-" She asked, although she couldn't even finish the sentence before Eiro interrupted her, "Because I'm not an idiot."
Hearing this short conversation, Solomon grew curious about what they were speaking of, "Eiro, Evelyn, what is the meaning of this? What kind of 'black blood' do you mean?"
