I am a nine-tailed fox, born with two demon cores. Years ago, I was captured by a Taoist priest, who, being kind-hearted, released me. Later, I pledged myself to him, and we spent a hundred years together. But that day, his junior sister lost her spiritual core and was near death. Without a word, he tried to dig out my demon core: "Qingqing, you already had two demon cores. Losing one won't be a big deal. Saving Qingci would be an act of kindness." What he didn't know was that when he was seriously injured, I had already given him one of my demon cores. Without my demon core, I will die soon. But it doesn't matter, I was born to descend to the mortal realm.
