On the night of their wedding, the new emperor Xiao Che discovered that the jade seal left by the late emperor could "manifest" - as long as the memorial was pressed under the jade seal, the reviewing pen would automatically write comments with sharp brushstrokes and vicious opinions. At first he thought it was the late emperor's spiritual guidance, until one day, on the Jiangnan salt tax case, Zhu pen suddenly wrote a line of instructions that was completely contrary to his thoughts: "Accurate memorial. However, Wang Chong, the Minister of Household Affairs, was dismissed from his post and investigated." Xiao Che felt a shiver in his heart - Wang Chong was the hidden stake he had buried for three years. Yuxi's comments began to contradict his decrees. What's even more strange is that the important officials in the court began to act in accordance with Yu Xi's "instructions" consciously or unconsciously. He gradually realized that the person trapped in this Fang Yuxi might not be the late emperor at all, but an "it" who was completely opposite to his political views and whose methods were even more ruthless. And inside and outside the court, there seemed to be people who already knew this secret and were waiting to see how he would be ignored by his own jade seal.
