The Wild Firstborn Daughter: The Prince Dotes on Her

Yin Youyue, a genius Mystic Physician from the twenty-first century, dies during an explosion while fleeing a dark organization and transmigrates into the body of a disreputable noblewoman in ancient Xuanyou Guo. The original host was the legitimate eldest daughter of the State Uncle’s Manor, known for her arrogance and shameless behavior toward men. Sent to her maternal grandparents, the Liu family in Bianhe Zhou, she was drugged and died after being framed for an illicit affair. Yin Youyue awakens in the same bed as a naked man, Xing Moyuan, who is actually a powerful lord disguised while tracking the Third Prince. Servants burst in, accusing her of infidelity, but she coldly rebukes them and claims the man is merely her male pet, shocking her aunt Bai Ruyan and cousin Liu Xinrou.

Bai Ruyan and Liu Xinrou have spent years systematically destroying the original host’s reputation and health under the orders of the State Uncle’s wife, hoping to prevent her return to the capital and her betrothal to the Crown Prince. They intend to lock Yin Youyue in the ancestral hall, where her frail condition would likely kill her. However, Yin Youyue reveals that Liu Xinrou is pregnant out of wedlock, causing chaos and allowing Yin Youyue to seize control of her living quarters. She asserts dominance over the abusive servants, including Nanny Bai, and forces them to provide her with proper food and care. During this time, she discovers a Medical System in her mind, a project she had commissioned before her death, which grants her access to advanced medicines and medical tools.

Seeking medicine to restore her deteriorating health, Yin Youyue visits Jiren Hall, a prestigious pharmacy owned by Ye Yixuan, a man Liu Xinrou loves. The staff and Ye Yixuan himself treat her with contempt, believing she is there to seduce him. Ignoring their hostility, Yin Youyue notices a dying child from the Blazing Fire Valley, a powerful faction of weapon makers. Despite the head physician declaring the boy’s condition incurable, Yin Youyue steps in and successfully treats the child using acupuncture and herbal medicine. Her medical expertise shocks the onlookers and earns the gratitude of the child’s father, Yan Xinhong, who offers her a substantial reward.

After the incident at the pharmacy, Yin Youyue returns to the Liu residence, where her uncle, Liu Lihu, confronts her for her recent behavior. Bai Ruyan manipulates the situation, claiming Yin Youyue has become violent and disrespectful. However, Yin Youyue counters by exposing the mistreatment she has endured, including being fed leftovers and dressed in rags. She threatens to report their cruelty to her parents in the capital, which terrifies Liu Lihu due to his ambition for promotion. Forced to back down, Liu Lihu orders Yin Youyue to be moved to the best courtyard in the estate and treated with proper respect.

As Yin Youyue settles into her new quarters, she begins to sell valuable items to fund her medical recovery. Meanwhile, Ye Yixuan visits the Liu residence, claiming he wishes to apologize for his previous behavior. His sudden change in attitude puzzles everyone, especially Liu Xinrou, who believed he was there to discuss their marriage. The narrative establishes Yin Youyue’s determination to recover her strength, uncover the truth behind her family’s betrayal, and navigate the complex political and social dangers of her new life while leveraging her medical skills and the support of the Blazing Fire Valley.
