A hundred years ago, the tenth son of the Dragon clan, Hai Ya, was born. She was a dragon girl. The dragon clan has always only had nine sons. The birth of the tenth son shocked all the gods. Then each clan divined disasters. The results obtained by the Dragon clan's tortoise shells were unclear, with good and bad fortunes interdependent. The Phoenix clan's results were the same. However, because the Phoenix clan's priests had some grudges with the Dragon clan, they declared that the tenth princess of the Dragon clan would bring disaster to the Phoenix clan, and ordered all Phoenix clans not to have any contact with the little princess. Then the dragon and the phoenix met without knowing it, and got to know each other and fell in love. A misunderstanding led to the dragon girl leaving sadly, and a secret conversation once again stimulated the dragon girl. In order not to cause trouble to anyone, whether her family or lover, the dragon girl resolutely chose to die. Who knew that her potentially powerful ability to travel through time and space would temporarily use her magic power? Hai Ya, who had lost all his time, was sent to that earth's time and space, named Qin Hanxin and grew up to the age of 20. On the other hand, Zhu Yan couldn't bear the pain of her lover's departure and the blame of her clan, so she chose to escape Nirvana and be reborn, losing all memories of her previous life, and becoming the patron saint of Feng Qi Country; the hatred between the Dragon and Phoenix clans was thus forged. The snake protects the phoenix and leaves the phoenix after 100 years. The phoenix looks for the snake in the dragon room.
