The heroine was originally a phoenix immortal of the Heavenly Court. She fell in love with another immortal, but that immortal was very cold and unwilling to accept the heroine. Later, the heroine did something with the devil. Anyway, it was for that immortal. As a result, the heroine was banished to the Beast Dao and became a chicken demon. The immortal felt very guilty and shared a trace of his soul.(It was probably a soul, anyway, it was separated from something). He separated another self and let him go to the mortal world to help the female lead cultivate and become a phoenix again. He went to the mortal world to take the female lead as his disciple and accompanied her on the mountain for more than 500 years.(After the female protagonist was banished to the Beast Path, she was reborn and could not remember anything.) The female protagonist fell in love with her master. One day, she secretly followed her master down the mountain and found that her master had been taken away by the heavenly soldiers. She wanted to save him and exchanged conditions with the fox spirit at the foot of the mountain: the fox helped her become a phoenix in advance to save her master. The price was that she had to cut off half of the flesh regardless of whether she succeeded or not. The female protagonist agreed to become a phoenix and killed many layers of heaven to see her master. However, her master scolded her and gave her a sword. She fell to the mortal world and fulfilled her promise. The fox cut off half of her flesh. Later, her master seemed to have escaped from the control of the immortal and went to find her. He found that she had gone crazy. Half of her face was covered by hair. When he opened her hair, he found that half of her face was covered by white bones.
