Jealous of her sister's popularity with the human they protect and the love she receives from the king, Mo Yin, the human form of Goddess Tengshe, colluded with the Demon Lord Shi You Ming to kill her sister Xian Yue. The act upset the balance between the God/ Human/ Demon worlds giving demons an upper hand. Xian Yue reincarnated as Ding Yao and returned to restore order. With the help of Wen Tian, a human-dragon hybrid, she set on a mission to re-forge the anti-demon vase using the holy pearls that Goddess Nuwa left behind from creating the human world.
