In ancient times, humans, gods, and monsters lived together, and Shennong, Xuanyuan, and Gaoxin were three kingdoms. After a hundred years of hardships, Gaoxin King Ji Jiuyao (Xiaoyao) who was exiled to the wilderness not only lost her identity but also her appearance. She settled in Qingshui Town and became Wen Xiaoliu, who "had nowhere to go, no one to rely on, and no way to protect herself." He made a living by practicing medicine and was unrestrained. Xiaoyao's cousin, Prince Xuanyuan, even though he lived under someone else's roof and endured dormancy, traveled all over the wilderness to find Xiaoyao and came to Qingshui Town. The days in Qingshui Town were plain and warm. Wen Xiaoliu accidentally saved the dying Qingqiu Prince Tu Shanjing, and the two gradually fell in love with each other as they spent time together day and night; Wen Xiaoliu also met the nine-headed monster Xiangliu, and they became close friends after a fight. Wen Xiaoliu and Xuanxuan did not know each other when they met, and after several twists and turns, she finally recognized Xuanxuan and restored her identity as a princess. In order to unify the world, Xuan gave up his personal feelings for the throne. After Xiangliu Shouyi died in battle and Xiaoyao helped Xuan complete his great cause, he and Tushan Jing retired to the rivers and lakes. Xuan, who was unable to achieve his goal, put all his energy into governing the country, because he knew that as long as the world was peaceful, his Xiaoyao would be happy and healthy.
