The modern part paved the way for Yun Nunu's professional skills (dissolving disputes, drafting apology plans, and coordinating relationships) → Traveling to the Qing Dynasty due to an accident while repairing ancient books with inscriptions → Relying on the ability to "mediate disputes" to establish a foothold among the people → Being noticed by Shen Yanzhi and recommended to the Metropolitan Procuratorate as a handyman → Using modern logic and communication skills to resolve conflicts between the government and the people, helping the people handle small cases, and gradually being promoted to Yuanwailang → Competing with Gu Yanchen, and being tested by Li Song → Helped Concubine Wan to resolve the crisis and then got involved in a secret fight in the harem (low point: framed for "interfering in the palace") → Shen Yanzhi and Su Qingwan teamed up to help clear the grievances → promoted to imperial doctor, and worked with Shen Yanzhi and Gu Yanchen to investigate corruption cases (high point: involved the interests of the powerful and were hunted down) → In the end, corrupt officials were brought down, but they also recognized the boundaries of officialdom, chose to pursue their own affairs in their positions, and protected their original intentions in an "alternative" way.
