Ye Shu, who had an accident while replacing a brain crystal chip, was ejected by a powerful force and traveled to the Spring and Autumn Period. Due to Gongsun Wuzhi's conspiracy, he was involved in the royal family and replaced the terminally ill princess Qi Wenjiang (Jiang Xuan). According to the historical data she had, she clearly knew that Gongsun Wuzhi was a villain who wanted to usurp the throne, but in the end she was deceived by his hypocritical words and deeds, and became Gongsun Wuzhi's political tool intentionally or unintentionally.
In another emotional line, she tried her best to avoid this notorious brother-sister relationship, but in the end she couldn't escape the trick of fate and was trapped in it, unable to extricate herself. Until one day, after the incident was exposed, in order to escape this sin, she followed Qi Gong's arrangement and married Lu Huan Gong, the king of Lu. In the State of Lu, after experiencing a lot of sorrow and joy, Jiang Xuan's love for Duke Huan of Lu gradually faded, and he finally understood that his marriage was just a political deal.
Therefore, she used the knowledge in her brain to help Jiang Zhuer, the new king of Qi, avenge the nine-generation feud between Qi and Ji, and fulfill the wishes of all the kings of Qi. He also helped Qi in its battles and laid the foundation for Qi's dominance among the princes.
Later, taking advantage of an alliance between Qi and Lu, the old relationship with Jiang Zhuer rekindled. Unexpectedly, Jiang Zhuer killed Duke Huan of Lu out of anger. Jiang Xuan was unable to return to the state of Lu and temporarily lived in Gongzui. In order to maintain the stability of the country, his son Duke Zhuang of Lu relied on the power of his uncle Qi Xianggong and watched helplessly as his mother and uncle turned a deaf ear.
However, she discovered a problem. Jiang Zhuer was no longer the prince he was back then. He had become irritable, did not distinguish between right and wrong, and had no royal bearing at all. He understood that Qi Xianggong had run out of energy. Facing the tyranny of his brother Qi Xianggong, he finally understood that in this world, he was the one who could always rely on him, so he took advantage of this opportunity to remotely assist his son in governing. It was not until Qi Xianggong was killed that he returned to the State of Lu. She was good at dancing and finally made the State of Lu a relatively powerful country, showing the talent and wisdom of a generation of female politicians.
Later, she accidentally discovered that Qi Xianggong's mental illness was caused by Gongsun Wuzhi, so she participated in eradicating Gongsun Wuzhi and helped the new king of Qi, Xiaobai, establish the hegemony of Qi.
