In the middle of the Dajing Dynasty, the new emperor ascended the throne for the first time and was determined to implement the New Deal in order to weaken the intertwined power of the aristocratic families. However, he was secretly restrained by the old noble group headed by Prime Minister Li. Chang'an, the capital, is the center of the power struggle. The political games in the court are intertwined with the grievances and grievances in the inner courtyard of the house. The silk brocade in the prosperous land in the south of the Yangtze River is not only the pillar of people's livelihood, but also a bargaining chip for the secret profit-making of all parties. The contradiction between it and the military supply of the northern border defense is becoming increasingly prominent.
The Shen family, a prominent family in the south of the Yangtze River, has been engaged in silk weaving for generations and is loyal and patriotic. However, because they have evidence that Prime Minister Li embezzled military supplies and colluded with the vassal king, they were executed by Luo Zhi on the charge of "collaboration with the enemy and treason." Only the legitimate daughter Shen Zhiyi was rescued by a loyal servant at the risk of death. From then on, she remained anonymous and lurked in the fireworks market of Chang'an, waiting for an opportunity to clear the family's wrongdoing.
