Lin Wanzhao, the daughter of the Lin family, a wealthy businessman in Shanghai during the Republic of China, was forced to marry into the Shen family of the enemy camp because her family was framed by a rival. On the night of the wedding, she was poisoned and faked to death. After her rebirth, she changed her name to Su Wan and became a female Chinese medicine doctor at the "Huichun Hall" in the French Concession. With the "Traditional Chinese Medicine Inheritance System" and her ability to identify medicinal materials, deduce prescriptions, and see through lesions, she gradually penetrated the enemy's business network and revealed the truth about the family's downfall. During the process, she discovered that her fiancé Shen Yanqing was actually the warlord marshal who secretly rescued her back then. The two went from testing each other to falling in love and killing each other, and finally joined forces to thwart the conspiracy of the powerful powers to plunder cultural relics and achieve revenge and redemption.
