The tradition of Yin Yue Kingdom has always been that women are superior to men, and the daughter is the king. After the king "Ming Yue" found the "mother's energy", he was jealous of the three realms and was cursed. The whole country would live in darkness forever without the sunshine. After Ming Yue, someone secretly told her that her fate was hanging by a thread. But when her life was dying, she gave birth to her daughter Xiao Mingyue. The prophet predicted that his daughter Xiao Mingyue would break this curse.
