A Tao transformed into the last spine in the blood and tears. The green hair on her temples and the never-fading moonlight are the mark of all the dead souls she bears. Every detail in the article is filled with coldness: the sound of crushing nails, black hair soaked in blood, bubbles on the frozen river... When I read it, I felt like falling into an ice cave, and after reading it, it burned into my bones. This is not a story, it is a bronze inscription made of suffering.
