According to legend, the Yinglong clan protects the world's good weather and good harvests. The dragon keepers are linked to their fate and protect nature and peace. However, there are only two imprisoned dragons and the last dragon keeper, Ping, left in the world. In order to save her hamster friend Huahua who strayed into the dragon cave, Ping took the risk and went deep into the cave. Her encounter with Danzi and Luyu accidentally revealed her true identity and awakened her dragon keeper energy. Ping also received a serious task - to send the last dragon egg in the world to Yulongtan for incubation, and the adventure and growth journey of one person and one dragon began. The story is adapted from the fantasy novel of the same name by Australian writer Carole Wilkinson.
