What William asked for was a small flute. Zin tried to blow air into it, tried to inject his spirit power inside, but all failed.
"This is the Dream Flute, one that's truly a scary item," William paused before adding, "to activate it, you need to use two antagonising elements you have, pour them inside, and let them explode inside and fuel it."
"I don't buy any of that," Zin had few spirit elements by birth right, but they weren't antagonising at all.
"Let me try it then," William simply extended his hand, and Zin looked at him in doubt, "what? Do you think I dare steal something from you?"
"You are shameless enough to do it!" Zin didn't hide what he was thinking about. And that brought out chuckles and smiles all over everyone watching this interesting talk between an old man and a youngster.
"Don't act like this, as if I can beat you or overrun you or something," William rolled his eyes and Zin finally complied.
