I was seventeen when I picked her up. She was a newborn, covered in blood and her lips were purple. The suicide note was soaked in blood, and no one saw the name. So I named her - Shen Yin. Because the night I found her, there was only the sound of wind on the back mountain and her very thin and light breathing. My name is Chen Shu. I'm an ordinary person. But I raised an extraordinary person. She awakened at the age of fifteen, went to war at the age of twenty-five, and spent half of her five-hundred-year life guarding the world for me.
