Zhao Chen, a graduate student in the Department of Modern History, accidentally traveled through time and became the Marquis of Yong'an, a down-and-out clan of Dajing. The original owner's absurd behavior made him a death row prisoner. The powerful officials in the Dajing court were domineering, and the barbarians in the north were eyeing him. While Zhao Chen in prison was making a living by relying on waterwheel drawings, he received a secret letter from Prince Jing Xiao Che offering food in exchange for military power. After being released from prison, Zhao Chen used modern wisdom to accumulate capital and emerged in incidents such as imperial examination fraud cases and border wars. However, villains such as the Prime Minister's gang and old nobles continue to set up traps and obstacles, such as salt and iron franchise traps and obstruction of the Young Miao Law.
Although Zhao Chen and Xiao Che cooperate with each other, they also have many misunderstandings and conflicts due to their different ideas and positions. In the process of implementing the New Deal, Zhao Chen faced a dilemma between interests and beliefs: whether to compromise with the old forces to gain short-term benefits, or to adhere to reforms to achieve long-term development of the country. At the same time, Dajing was experiencing internal and external troubles, and the barbarians from the north might invade again at any time, leaving them with a tight time limit to reorganize the court and defend against foreign enemies.
In repeated confrontations and cooperation, they gradually resolved misunderstandings and worked together. But behind the success are the sacrifices of countless people and the difficult choices they had to make. In the end, it is still unknown whether they can create a bright future in this war of power and conspiracy.
