Now that the agreement had been made, Amelia asked, "May I know what materials you need? I will have my servants secure the materials for you."
"In that case…" Nathan raised both hands, making a gesture as if there was something in his hand. "I need a mineral that can store energy. That is the foundation of this device."
"What?!" Amelia, the manager, and even the high-level summoner couldn't help but open their mouths in shock.
"Is there something wrong?" Nathan frowned, wondering if this was a rare mineral on this continent. He didn't know the name of this mineral on this continent, so he explained it in a vague way.
To his surprise, Amelia explained, "No. There's nothing wrong. This mineral is the most worthless mineral. How much do you need?"
He didn't understand why this mineral would be worthless. However, if it was indeed worthless, he might be able to get it in large quantities through them.
