Pei Xingjian, a doctor of full-level literature and history, travels through the Yong Dynasty. At the beginning, he is actually regarded as a scapegoat by his family and is about to be sent to the Jedi for his brother's bastard. There are many clans in Dayong, strict etiquette and class barriers are like natural chasms. Faced with clan strife and a life-and-death crisis, Pei Xingjian had no system, let alone force. He only had the vast ocean of cultural and historical heritage in his mind and his absolute insight into the feudal patriarchal system. Are you talking to me about dignity? I use the "Dayong Rules" and "Book of Rites" to teach you how to behave! Using the dead to oppress the living, and using family rules to break the family law, Pei Xingjian fought back in the murderous side courtyard, stepping on the pride of a high-ranking family, from imperial examination to officialdom, to power in the government and the public. Using etiquette as a sword and history as a situation, let's see how a humble concubine can tear apart this prosperous family and rise to the top step by step, with the purple robe at the top!
