"What is this?" Catherine took the dark little stick from Pannis's hand, feeling its unique texture. Softer than normal wood and more flexible, it wouldn't break even when bent at a right angle. She examined it in the light for a while, unable to discern anything. The only result she got was her fingers stained black as if she had been holding a piece of charcoal. The knight girl casually rinsed her fingers with water, becoming even more convinced of the charcoal-like texture and couldn't help but ask in confusion, "This thing is really strange, but why show it to me?"
"You don't know?" Pannis made a surprised face and exaggeratedly exclaimed, "Good heavens, you actually don't know!"
"Big sis, this is a type of casting material, called Wood Essence," Vivian took the black object from Catherine's hand, playing with it as she spoke, "A really rare thing; it's buried seven or eight thousand kilometers underground, even Dwarfs can't dig it up easily."
