This is a classical fairy tale about a female doctor who time-travels and establishes herself, balancing medical practice and managing her husband. This is a love story between an intelligent female protagonist and a strong male protagonist. Ending: V, HE. Yao Fengge, the eldest daughter of Governor Yao Yuanzhi, is critically ill. In order to benefit the family, the Yao family arranges for Yao Yanyu, a concubine-born sister, to enter the post-marital residence of Lord Dinghou. They only wait for the death of the legitimate daughter before designating Yao Yanyu as the official wife. Yao Yanyu, a modern female Ph.D. in Western medicine, spends ten years incognito in the Yao family, hiding her capabilities and waiting for the right moment. She doesn't want to marry someone second-hand and live her life in mediocrity. She uses the leverage of healing her legitimate sister to obtain her freedom, leaves the mansion, and goes to the countryside for a peaceful life. Unexpectedly, she abandons all constraints and leaves the Hou Mansion with her meager possessions, but her peaceful life doesn't last. Living alone in a mountain estate, farming and raising chickens, she attracts the attention of a playboy and a fierce military general who come to visit her in succession. Since then, the family values her, her father and brothers cherish her, her legitimate sister cares for her, and her brother-in-law pities her. Life turns into a myriad of beauties, with constant deceit and unfading wealth and glory. Yao Yanyu once said, "This young lady is neither skilled in embroidery nor knowledgeable in chess, calligraphy, painting, or music. I have no looks or manners, and I have a strange temperament. I am not suitable for a family or a husband, and I am not a good match for you, sir." Yao Yanyu also said, "If a woman can stand on her own in the world, why would she need to marry? Finding a man is just equivalent to finding trouble for oneself." Yao Yanyu further stated, "When a woman marries, she not only brings her dowry but also has to support her husband and raise children. And if one day she dies accidentally, she has to leave her dowry for another woman to enjoy. It is truly an unprofitable deal." To sum it up, I live well on my own. Why do I need to marry? Su Yuxiang said, "When your parents sent you to my house, you became mine. Even if your legitimate sister doesn't die, you are still a member of my Su family." Su Yuxiang continued, "Whether you are a concubine or an official wife, the story of you two sisters is still a beautiful tale." In short, Yao Yanyu, you can only be my woman in this lifetime! Feng Shaochen said, "Only because of one glance from you, I am constantly thinking about you day and night. Yan Yu, Yan Yu, do you know how much I long for you?" Feng Shaochen continued, "The small longing message cannot express my deep affection for you. Yan Yu, I cannot eat or sleep without you. I only wish to grow old hand in hand with you." In short, Yao Yanyu, without you, this young master cannot live. I am bound to you in this lifetime! Wei Zhang said, "Since childhood, I have been independent. I don't need you to take care of my clothing, food, shelter, or transportation. General Wei's parents are deceased, I have no elders to serve." Wei Zhang continued, "I will give you my 3000 acres of land, 1000 households to support, 600 buildings in the general's mansion, countless treasures, 600 servants, and 1200 soldiers. All of these belong to you. If there are no objections, I will request the emperor's order for our marriage tomorrow." Wei Zhang declared, "I promise you: I won't take concubines, and we won't be separated until death." In short, the person I, General Wei, chooses, I will do anything to obtain. Anyone who dares to compete with me will suffer an unbearable fate!
