In the second book about the dragon princess, Liu Yi miraculously travels to the luxurious palace of the dragon king under the water of the lake. He delivers the letter from the Dragon Princess to her father who is overcome with remorse for having ignored his daughter. The Dragon King is full of gratitude to Liu Yi who has faithfully brought the letter from the world of humans. Just then the king’s violent and powerful brother dragon appears dramatically amidst thunder and lightning and frightens Liu Yi. When Liu Yi has calmed down, the king arranges a feast for him where Liu Yi is surprised and pleased to find that the beautiful princess has already somehow returned to the palace.
The sumptuous palaces, the presence of dragons in thunder and lightning and the belief that the dragon kings controlled the waters of lakes and rivers are all traditional Chinese beliefs and legends.
