On the surface, Lu Jinzhi is a student of St. John's Medical College and the heir to the Lu family pharmacy. In fact, he inherits the legacy of his brother Lu Qiming. He uses the pharmacy as a cover to secretly deliver medicines to the front line, and starts a battle of intelligence and courage with Japan's Mitsui Trading Company. In crisis after crisis, she gradually uncovered the secret identities and complex positions behind her father, cousin Shen Mengdie, accountant Lao Chen and others, and also discovered surprising clues that her brother may still be alive.
As incidents such as the "Penicillin Batch Number Mystery", "Angelica Project" and "Ci'an Tang Connection" progressed, Lu Jinzhi continued to make choices between the survival of his family and the justice of the nation. With the wisdom of a doctor and the courage of a warrior, she stuck to her faith in Shanghai, shrouded in mist and rain, paid "diagnosis fees" and guarded hope.
Purpose: When the country is in crisis, personal sacrifice and choice create the immortal backbone of the nation
