In order to protect the little prince Jing'er, whom her sister had sacrificed her life for, Lin Ran moved into Fengyi Palace. She was ignorant and crying when she first entered the palace, but she gradually matured in the trials and tribulations of the palace. While learning to deal with palace etiquette, taking good care of the prince, she also resisted the conspiracy and calculation in the dark. After learning that the emperor sacrificed her sister to seize power, she united with like-minded people and challenged the chess player with her medical skills. After completing her mission, she resolutely put everything aside and pursued her own free life.
