In the troubled times of Daliang, Shen Hengzhi, the concubine of the Hou Mansion, was abandoned by her family and replaced her eldest sister and Prince Xiao Yan. When he first entered the palace, his stepson was as timid as a mouse, his stepdaughter was arrogant and domineering, her husband looked on with cold eyes, and the power of the family was controlled by the concubine Xie Zhaohua. What's even more fatal is that during the Royal Heavenly Sacrifice Ceremony in the twelfth lunar month, if there is even the slightest mistake in the prayer session she presides over, the entire palace will be buried with her. Shen Hengzhi did not argue or argue. She held a volume of "Etiquette Tongjian" in her hand. She endorsed it to the emperor's son in the morning, punished his concubine to copy scriptures in the afternoon, and handed her husband a bowl of soothing soup at night. She used her upbringing methods to make her stepson memorize the "Book of Filial Piety" in three days, and used the blade of etiquette to expose Xie Zhaohua's conspiracy to secretly change the sacrificial vessels. Xiao Yan went from cold probing to dressing her up late at night: "Princess, you want to take charge of the family? I will clear the way for you." That month, the Queen Mother issued an order to take back Xie Zhaohua's custody of the prince and give full power to Shen Hengzhi. The Shen family who had abandoned her knelt outside the gate of Jiankang City and begged her to return home and recognize her ancestors. She only smiled across the curtain: "The Shen family's ancestral hall is dirty." But a bigger storm was coming - the Northern Yan army was approaching, and the four major families in Jiankang City joined forces to force King Yong to hand over military power. Shen Hengzhi stroked her stepson's head: "Son, I'll teach you the first lesson in the art of emperorship: how to make the enemy kneel down and beg you."
