Lan Shi was originally a modern historian, but his soul accidentally traveled to a powerless official in the prosperous age of Kaiyuan. He was keenly aware of the hidden dangers behind the superficial prosperity. Not only were various forces within the palace fighting for power, but also foreign enemies were eyeing the invasion. Wu Hua is an unpopular concubine from a noble family. Although she is in trouble, she has a righteous heart. After the two met, they decided to work together to protect the people.
However, in order to protect their own interests, the villain forces obstructed them at every turn. Due to Lanshi's low status, his modern ideas and behavior were misunderstood by ancient powerful people, causing many misunderstandings. They not only have to face the complex power struggle within the palace, but also have to resist the invasion of foreign enemies within a limited time. In the process, Lanshi and Wuhua continued to grow, using modern knowledge to stir up the market, crack down on political conspiracies, and gradually establish their own power. But in the struggle for power, they face a dilemma: whether to stick to the bottom line of modern morality or to make appropriate compromises to achieve their goals. In the end, they successfully resisted foreign enemies and reshaped the social order, but they also experienced a lot of bitterness and sacrifice in the process.
