After the explosion in the laboratory, Lin Zhao, a 26-year-old graduate student in traditional Chinese medicine, opened her eyes again and became a 15-year-old concubine of the Yongchang Hou Mansion in Dazhao. Caught in a whirlpool of house fighting, she used modern medical techniques to break the situation, but unexpectedly awakened the ancient medical scripture "Nine Volumes of the Spiritual Pivot". From then on, the weak concubine embarked on a journey from the deep residence of the prince's mansion to the secret bureau of the palace, from hanging a pot to help the world to cultivating immortality and seeking enlightenment.
She rescued her sister-in-law, fought against her stepmother, stirred up the chaos in the court with a silver needle; met the prince, met the medical fairy, and kept her benevolence amidst the machinations and Taoism. The seemingly frail prince Xiao Chengyu is actually a forbearing prince who has been hiding for many years. From using each other to relying on each other in life and death, the two jointly uncovered the secrets of the previous dynasty and the conspiracy to cultivate immortality.
When the gate to the underworld opened and the plague raged, Lin Zhao resolutely faced the catastrophe of heaven and earth as a doctor. From "seeking for life" to "saving people", she finally realized that the way of medicine is the way of humanity, proved the way to immortality with the most kind heart, and wrote a legendary chapter of a generation of medical immortals.
