"Fearsome" hardly described Usopp, or the enthusiastic hug he sprung on Yuber. Yuber was obviously less-than-pleased by Usopp's thanks, in a pretty funny way-- a few years ago, Zelnick probably would have laughed at Yuber's expense. As it was, he drew a few drops of tact and managed to keep his reaction down to a quickly-muffled amused noise.

"Yeah, saltpeter, too," Zelnick said, amusement clear in his tone, despite his best efforts. "As much as I could find. Also ethanol, ammonia, formaldehyde, hydrochloric acid..." Not as nice as missiles, but still plenty deadly. "Oh, and a mortar and pestle. Which will probably be useful," he added. "I don't suppose you have sulfur or charcoal on hand for gunpowder? Or even just charcoal?"

At Sai's question and Yuber's reply, Zelnick shrugged. "Resources are never a bad thing." He'd been short on them often enough... "I wouldn't mind looking for more."
