Karlo collected himself, saying, "If your scrolls truly have such incredible effects, I agree to all of these demands, but for safety's sake, I'd like to try one of your fourth-rank scrolls. Let's go somewhere else."
Nian Bing thought to himself: This president of the Mercenary Guild is really extravagant, using two hundred purple gold coins for an experiment...
The two moved to the yard where Nian Bing took out a scroll from his spatial ring and tossed it to Karlo. The moment Karlo saw the scroll was made of top-grade white scroll material, he was already partly convinced. After all, the value of a regular fourth-rank scroll isn't even worth a top-grade white scroll. Using it to make a fourth-rank magic scroll reveals the value of this scroll.
