This chapter begins with a flashback to a time when Lin-shan was a child. He is now a young man, but he is still very much a member of the family. He has been trained in body refinement, and he is eager to learn more about the art of medicine. He wants to know how he can use the healing powers of the stone to improve the health of others. He explains that he makes a medicinal liquid from the stone and then exchanges it for a grade 3 elixir. This medicinal liquid is useful for those who want to train body refinement. He says that he does not have the money to buy the whole thing, so he will find another store. The medicinal liquid he makes is a mixture of ten drops of the medicinal liquid and one drop of the grade 3 liquid. This is a very useful medicinal liquid for anyone who wants to improve their health. Lin-Shan explains that when he makes the mixture, he only needs to collect ten drops. He can then exchange the ten drops with five stalks of the same grade 3 medicinal liquid. The difference between the two amounts is that the first ten drops are pure medicinal liquid, while the second ten are pure elixirs. This means that Lin-Sung can buy the same amount of medicinal liquid as he can buy any item without having to pay anything for it. This way, he is able to exchange medicinal liquid with any item that he wants without worrying about buying it. He also explains that the rune-stone produces the same medicinal liquid that he can exchange for any item he wants. This allows him to buy anything he wants from any store at any time. He even buys a hair pin from the cake shop.
