"What's that?" Yorko stared at the illuminating object in surprise despite its dazzling light. "Is it also something you sell in the exhibition?"
"It has several names. For example, Sun Stone and Light Crystal... but we prefer to call it Magic Stone because it's said the stone comes from the lairs of demons." No. 76 explained in a low voice. "'Black Money' once sold them in an auction, and the final bidding price was around 2,000 to 3,000 gold royals. They're expensive and rare, so they won't be sold in every exhibition. At least, it's not included in the list of products for sale tonight." She paused for a second and asked, "Sir, is this your first time to come here?"
"Well... sort of." Yorko stroked his nose to conceal his uneasiness. If one stone cost that much, then all the magic stones used for illumination on the stage would be worth more than 10,000 gold royals. This was just such a lavish exhibition!
