Xu Qing was originally the arrogant eldest daughter of an aristocratic family. When she was five years old, her father and grandfather turned against each other, and her parents were expelled from the house. Her mother gave birth to a younger brother and died in childbirth. Her father was seriously injured and passed away soon after. With her eldest sister just like her mother, she hunted and worked in a small town to support her frail and sick younger brother. She expected that her life would be nothing more than a life of loneliness and dependence. However, she did not want to be involved in the family succession struggle, and she became a pawn in the conflict between her grandfather and her second uncle. In order to save the life of her younger brother and regain her father's glory, she went out with a sword, fought with the gods for fate, and fought with others, vowing to find a path to immortality in this troubled world.
