Sea ​​Palace

I am Yi'er, the most beloved princess of Juanshui Kingdom. My dormitory is on the highest spire in the capital. The spire is shrouded in a layer of red light that no one else can approach all year round. My father said that it is a guardian sent down for me. When I was nine years old, the prince pierced my body with a short knife deeply. In the severe pain, I saw my blood stained clothes and the deep fear in the prince's eyes. Before my consciousness dissipated, I was carried into the dark room by my father. I seemed to see a jade sculpture similar to me. Could that look like my mother who died in childbirth? I thought the pain would dissipate over time, until many years later I finally understood the fear in the prince's eyes. He who gets red blood will conquer the world. Who am I and why am I here?
