In this chapter, we learn that the tulip family has been making glassware for many years, and that the first duke of the family, who was a transmigrator, has been in this business for a long time. The elves, who are also known as "children of nature," like to buy and sell things, but they can't do it on their own. They need to buy things from human beings, which is why they have so many factories. The only problem is that the elves only accept gold coins and gems for transactions, which makes it difficult for them to get their hands on some of the rarest and most precious items.
