"Aldred, how did you do that? How did these golems use spells without mana crystals?" Zafrina asked.
"I use my own mana, and put it inside of them. There are limits to how many they can contain according to their size and materials though."
"If I use mana crystals on them, they can have far larger capacities, and even regenerate their own mana. But I found something out."
"What is it?"
"Look at this." Aldred raised his palm, and then blue mist started to form on his palm, before it condensed into a crystal.
"It's a mana crystal!" Zafrina exclaimed. "But it's not an elemental type crystal. It's pure mana."
"Impossible!" Mary stared with widene eyes. "Mana crystals formed through condensation of the world-elements, and pure mana crystal was never seen before."
Aldred smiled. "Just like you said, Mary. It's a condensation of elements. I just have to condense my mana into a physical state."
