Su Li, an abandoned disciple of Yaowang Valley, went down the mountain due to a strange plague, but unexpectedly uncovered a shocking conspiracy. She uses silver needles as blades and medical skills as strategies. In the turbulent court and rivers and lakes, she not only wants to find out the truth about the fire in Yaowang Valley twenty years ago, but also uncovers her dual life experience as "the saint of Yaowang Valley + the illegitimate daughter of the royal family". She fights side by side with her like-minded confidant Gu Qingyan, against the ambitious concubine Xian, the cruel and suspicious second prince, and the sinister Mingcha organization. In the game of revenge and perseverance, scheming and medical skills, Su Li finally fought back from the bottom, stirred up the storm with his medical skills, and became a generation of medical immortals, adhering to the original intention of "the benevolence of a doctor".
Purpose: to use medical ethics and benevolence to fight against power and conspiracy, to explore the connection between personal destiny and family, country and world, to show how women break through the shackles of identity in revenge and perseverance, and to protect justice and common people with their own strength. At the same time, it emphasizes the tacit understanding and morality among comrades and confidants, and finally realizes the unity of personal values and the justice of the world.
