Jiang Nuan, a modern female doctor, travels through time in a car accident and becomes the legitimate daughter of a waiter who was bullied in ancient times. While relying on her superb medical skills to save herself from trouble, she unexpectedly saved the son of her old enemy, which attracted the attention of General Xiao Beichen. In order to escape the engagement arranged by her stepmother, she reached a deal with Xiao Beichen, who was pretending to be a businessman, and went with the army to the border to treat strange diseases. During the epidemic crisis, she used modern medical wisdom to achieve miracles repeatedly, but she was involved in a military power struggle. When Xiao Beichen was trapped in the enemy camp to get medicine, Jiang Nuan did not hesitate to use fireworks to send a message to expose his position; when he was forced to marry the princess, she used curing the Queen Mother's chronic illness as a bargaining chip to deal with the court. From mutual use to life and death, the silver needle and the long sword intertwined a legend that spans time and space.
Purpose: Through the growth and struggle of modern female doctors in the adversity of ancient times, it explores core themes such as the benevolence of doctors, female awakening, and class breakthrough.
