This is a world where humans and feathers coexist. After a long war, the two very different races finally ushered in a short and fragile period of peace. However, the star stream pollen that the feathers rely on for survival is becoming increasingly scarce, making the feathers increasingly weak. At the same time, the human race secretly created the Sky City to balance the feathers, and a fierce battle between the two races is inevitable. Yi Fuling (Guan Xiaotong) is an ordinary girl of the feathers. In order to find her childhood sweetheart, the human prince Bai Tingjun (Liu Chang), she did not hesitate to leave her hometown and travel through mountains and rivers. However, the feather emperor Feng Tianyi (Zhang Ruoyun) was involved in trouble with Yi Fuling by mistake, and Feng Tianyi had long known that Yi Fuling's true identity was the reincarnation of the star stream flower god that was rare in a century. However, if the star stream flower god in Yi Fuling's body awakens, it means that Yi Fuling, a simple and lovely girl, will no longer exist. In order to protect his most beloved person, Feng Tianyi does not hesitate to be an enemy of the whole world.
