In 2025, Zhang Ke, a history student at Nanjing University, accidentally traveled to Yuncheng County in the late Northern Song Dynasty and became the county government official. Faced with the troubled times when officials were corrupt and people's livelihoods were in decline, he used modern knowledge as an edge to rewrite the plot of "Water Margin": he wisely changed the birth plan and taught the formula of simple explosives; he proposed "equalizing land and exempting taxes", transforming the Liangshan Rebels from grass bandits into a prototype of a political power that implemented the New Deal. He designed the "Three-Three System" tactics, improved firearms formations, planted "earth-shaking thunder" with magnetic fuses in Poshui Village in Liangshan, used parabolic artillery to severely damage the Jin Army's Iron Pagoda in the Julu Plain, and promoted the governance concept of "people's livelihood is combat power" in the tug-of-war between Jiangnan and Fangla.
From the counselor who outsmarted the birth plan to the architect of the Dashun regime, Zhang Ke has always wandered in the gaps of history: he used the name of recruitment to reserve strength, connected the grassland tribes with trade strategies, integrated modern management concepts into the ancient official system, established the Ministry of Civil Affairs, the Ministry of War, and the Ministry of Justice to perform their respective duties, making the land deed of "land to the tiller" the foundation of the new regime. When Song Jiang ascended the throne of Mount Tai, Fang La bowed his head and proclaimed himself a vassal, and the Kingdom of Jin submitted a peace treaty, he retreated bravely, leaving behind the stone tablets of "Government of the World" and "Practice for Heaven", hidden deep in the reeds of Liangshan Mountain.
Hundreds of years later, the bronze cannons from the Shuntian Mansion Site, the fragments of the "Government of the World" from the Dunhuang Buddhist Scripture Cave, and the pens from the Old Sophora Tree Cave in Yuncheng jointly piece together the legend of a time traveler - he did not rewrite the dynasty changes recorded in the history books, but planted the fire of "the way of heaven is the people's heart" in the hearts of millions of people, transforming "the way of heaven" from the slogan of the world into the eternal pursuit of institutional justice.
