The Tianhu clan was jealous of the Emperor of Heaven, and the Manchus slaughtered them all. Princess Yue Ya was forced to have her memory sealed by the Queen of Fox with the Nine-Xuan Heavenly Jade, and was pushed into the Forgotten River to escape as a white fox. She was adopted by a mortal and named Jiuniang. It just so happens that the soul of a female politician from her previous life has passed through this body. She has no golden fingers around her and can only rely on her power and tactics to make a living in Qingqiu. Qingxuan, the Lord of Qingqiu, is actually the ancient demon king. In order to wash away the "despicable" destiny of the demon clan, he has laid out the three realms for a hundred thousand years. He resurrected his body and hid it in the body of Xuan Yuan, the second prince of the Tian Clan, and started a war between gods and demons. After the defeat, he hid in Xuan Yi's body and lay dormant, waiting for the right time. He chose Jiuniang as the cauldron of the ten-tailed demon god, hoping to use her to supplement the demon god's original power and escape his fate. The two of them stirred up the turmoil in the Three Realms as chess players. Qingxuan aspired to the Three Realms, but pushed Jiu Niang into the tenth life trial to sharpen her character and strengthen her bones. Little did they know that they were already entangled in love and desire without realizing it. After ten lives of love and hate, Jiu Niang finally breaks the relationship, cuts off the cause and effect, and achieves the completion of the ten tails. She vowed to overthrow this hypocritical way of heaven, but Qingxuan teamed up with the Emperor to suppress her. In order to protect the people of the three realms from being refined by Qingxuan, Jiuniang cut off her ten tails, abandoned her body in the cauldron, and lost her soul. Qingxuan was in great mourning, but he used the power of gods and demons to reverse time and space. Jiuniang was reincarnated as a human princess, and returned with the memories of two lives. She used Qingxuan's obsession as a blade to sweep through the enemies of the three realms, kill the Emperor of Heaven with her own hands, and finally avenge the annihilation of her clan and unify the three realms. The cause and effect of the three lives has come to an end, and all love and hate have turned into ashes. Jiuniang breaks free from the shackles of fate and love and no longer lives for anyone - between heaven and earth, she finally becomes a free ten-tailed celestial fox.
