In this chapter, we learn that willpower is the key to success. We learn that our little girl, Wenxin, is a "person of willpower" and that she will get the best results from anything she does. We also learn that she is a princess, which means she is equally noble as a prince and a mermaid. The mermaid asks the sea witch to give her legs in exchange for her voice, but the mermaid says that she would not do such a terrible deal. The princess does what she says. She observes the merchant ships and listens to the sailors. She then organizes an army and uses the sea resources to trade openly with humans. What happens next? The princess then becomes the lord of sea. All countries that wish to trade on the sea must visit her at her underwater palace. The sorcerer of mankind invents a potion that costs more than gold and transforms the prince into a mermaid in order to gain a trade permit. When the prince arrives at the palace, he realizes that the princess is not just a princess; she is actually a queen.
