Xie Jinxue's real name was Jiang Zhaoning. When he was eight years old, the entire Jiang family was falsely accused of rebellion and was stained with blood. She was rescued by a loyal old servant, but she lost her memory due to a high fever. She was adopted by the hidden medical fairy Xie Qingya and renamed Xie Jinxue, which means to burn away the past and wash away the grievances.
For twelve years, Xie Jinxue devoted himself to studying medicine and secretly collected clues about the tragedy that year. She had superb medical skills, but had a certain coldness until she met Xiao Yanci, the king of Yanbei. Xiao Yanci seems to be cynical, but in fact he has the world at heart. He met Xie Jinxue when he was investigating the corruption case in the court. The two worked together to investigate, supporting each other in dangerous situations, and their love gradually grew.
As the truth gradually emerged, Xie Jinxue discovered that the man behind the scenes was actually the elder brother of the current queen and a highly respected left prime minister. Facing the overwhelming power, she ignored Xiao Yanci's dissuasion and ventured into danger alone. In the thrilling confrontation, Xiao Yanci was seriously injured in order to protect her. In the end, Xie Jinxue exposed the crimes of the left prime minister with her poison-treating skills, but Xiao Yanci was too seriously injured and closed his eyes in her arms. Xie Jinxue, whose great revenge had been avenged, filled her heart with sorrow and turned the rest of her life into a long song in memory of her lover and the Jiang family's grievances.
