Cao Zhaohe, a medical student at Beijing University of Medicine, came from a humble background, but he opened the doors of the rich and powerful with his first-hand family pulse diagnosis. She nursed the body of Qin Hengzhang, the old man of the Qin family, and met his grandson Qin Shiyong for the first time - a business tycoon with an invisible edge. An autumn rain, a pursuit, she glimpsed the blade under his skin, and he saw the soft light in her toughness. Doctors don't ask where they came from, and the hidden blade must eventually be sheathed. When a silver needle meets a gunshot wound, when an ancient book collides with a secret file, can two "undocumented" people be each other's antidote in the turbulent capital?
Purpose: To explore the personality independence and self-persistence of contemporary women in the crisis-ridden reality. Love is never a haven to escape from the world, but two people covered with scars understand each other and rely on each other, but do not constrain each other's ideals and original intentions. The story uses the scientific research of traditional Chinese medicine as a clue to show the unique value of traditional medicine in today's world, and depicts the appearance of ordinary people who always stick to their ideals under the influence of profit and conspiracy.
