What is the life of Xiao Jiu?
The nine-tailed fox fights Jiang Ziya in the film. Jiang Ziya was supposed to be killed in one blow. Suddenly, a little girl emerged from the tail of a nine-tailed fox. This little girl is Xiao Jiu. The nine-tailed fox threatened Jiang Ziya that if he killed her, the little girl would die. Finally, Jiang Ziya released the nine-tailed fox, and Jiang Ziya was banished from the mortal world.
At the end of the film, Xiao Jiu's life story was finally revealed. It turns out that Xiao Jiu is just an ordinary girl named da ji. She looked fresh and refined and kind-hearted, but then her temperament suddenly changed, just like a different person. It turns out that the nine-tailed fox is attached to Xiao Jiu and controls all the behaviors of Xiao Jiu, and the two will share life and death. Jiang Ziya didn't want to hurt innocent lives in the war with the nine-tailed fox, so in order to protect Xiao Jiu's life, he chose to give up hunting the nine-tailed fox.
Xiao Jiu, possessed by a fox demon, later became conscious of himself. She didn't want to be used as a puppet by monsters to hurt innocent people, so she asked Jiang Ziya to kill her. Finally, Jiang Ziya promised her. For the sake of the whole world, Xiao Jiu chose to die with the nine-tailed fox.
