Chen Xuan, a graduate student in the Department of Modern History, traveled back to the Wanli period of the Ming Dynasty in an accident. At this time, the Ming Dynasty was plagued by internal and external troubles, fierce party struggles in the court, people's livelihood was difficult, and border wars continued. With modern knowledge and understanding of history, Chen Xuan is determined to change this era. He started from the bottom and met like-minded partners, such as the witty and brave female detective Lin Wan'er, the world-minded scholar Su Yu, and the skilled craftsman Zhao Tie. Under the leadership of Chen Xuan, they set off changes in the fields of business, technology, military and other fields, and launched a fierce struggle with conservative forces. They finally succeeded in bringing the Ming Dynasty to new prosperity and opened an unprecedented historical chapter.
