I am a stone. I don't know when I became a spirit, but I know that I practice to become an immortal. I don't know where this idea came from. I just know that a gentle voice has been reminding me since I was born: Ammu, I want to become an immortal and protect myself. When I was getting closer to becoming an immortal, I met him and he told me that he would protect me forever. What I know is that what he wants to protect is not me, but my stone heart. Maybe God took pity on me and saw that I had such a stupid and unenlightened brain, so he gave me a stone heart that can gather my soul. Yu Ming told me that my stone heart was very precious and I must not let others know about it. But, he didn't know that this stone of mine was contaminated by the love and affection of the world, and I was just like the girl in the storybook, who lost her head and was deceived by him, ending up with her body completely destroyed and her soul scattered. When he hugged me and called Amu, I knew he was not calling me. I touched his face and said slowly: "I am not that Amu. Aheng, I am tired. I will never love you again in the next life. Let's let each other go, and we will have nothing to do with each other from now on."
