In April of the 25th year of Hongwu's reign, Prince Zhu Biao was critically ill. Zhu Zhe, a modern civil servant, accidentally traveled through time and became Zhu Yunxi, the second son of Zhu Biao, and found himself at the most delicate historical node of the Ming Dynasty. Facing the tragic fate of being deposed, poisoned and executed in history, as well as the civil war and seclusion that Ming Dynasty was heading towards, Zhu Yunxi was determined to use "On Contradiction" and "On Practice" as ideological weapons to start a road to change his destiny against nature. On the surface, he is humble and tolerant, but secretly adopts the strategy of "surrounding the city from the countryside"; through the remnants of his mother's Huaixi Group, he contacts the old and central military departments, uses the principle of "seeking truth from facts" to promote high-yielding crops to improve people's livelihood, and uses the "mass line" to cultivate talents from poor families. When dealing with Zhu Yunwen and his civil servant group who advocated empty talk, he insisted on the "united front" strategy and united all the forces that could be united - analyzing the contradictions among the kings; King Qin's tyranny lost the hearts of the people, King Jin was suspicious of power, King Yan was talented and great but his reputation was not justified, King Zhou was obsessed with academics, and King Xiang was strong and easy to break. Different strategies were adopted for different personalities. He and Xu Da's daughter Xu Miaojin (sister-in-law of Zhu Di) went from political marriage to knowing each other. They supported each other on the road of reform and jointly faced the heavy pressure from the family and the court.
After the battle for the reserve position in the late years of Hongwu and the turmoil in the early years of Jianwen, Zhu Yunxi finally reversed the situation at the critical moment of the Jingnan Campaign, defeated the Yan army with a new army with improved firearms, and started the "Yongxing Era" after he ascended the throne. Implement the cabinet system to reform the government, open the Ming Bank to activate the economy, build new schools to cultivate talents, and build an ocean-going fleet to usher in the age of navigation. Under his leadership, it became an "empire on which the sun and moon never set" in the true sense.
