Zheng Nianru went from being a Commandery Princess who could be killed at any moment to the position of the Empress Dowager, wielding power over the world. What she couldn't accept was that she didn't end up with a good fate. However, Zheng Nianru thought that no one would have been able to save Nanzheng State.Yet, she was reborn and, having deeply reflected upon her pain, also considered several past mistakes. Firstly, she should not have married down into the family of Ju Nanyi, a man with a narrow mind who came from a minor house, who only thought about romantic affairs and entangled with her in desperate affection, incapable of assisting Nanzheng. Secondly, she should not have killed everyone in Qiandao Temple, which was the spiritual pillar of the people of Nanzheng State. After all, there were better ways, weren't there, like seduction? Thirdly, she should not have been so confident that the monarch of the neighboring country would fall at her feet, nor should she have trusted the promise of that fickle neighboring monarch, which led to years of drawn-out conflict between the two states.Um, Zheng Nianru felt she was not wrong. She just wanted to live well and to be a good Empress Dowager. Since she had the chance to live again, why did she have this chance? Could it be that she was expected to once again turn Nanzheng State upside down?
