Ming Dynasty: Charge, Yongle Emperor!

In the early Hongwu years, the newly established Ming Dynasty faced persistent threats from the Northern Yuan remnants and unrest across its borders. A soul from the modern era transmigrates into the body of Zhu Di, the fourth son of the Hongwu Emperor. Armed with foresight and ambition, this reborn prince leads campaigns into the northern steppes, subdues the Mongol tribes, and achieves legendary feats at the ancient battlegrounds of Langjuxu and Hanhai. He opens border markets, lifts the maritime ban, conquers Japan, and projects Ming power across the Western Oceans. He fosters industry, pioneers new schools of thought, establishes banking systems, and founds overseas colonies—steering the Great Ming Dynasty onto an entirely unprecedented path. In the ninth month of the twenty-fifth year of Hongwu (1392), the Crown Prince Zhu Biao passes away, and his son Zhu Yunwen is named the Imperial Grandson-Heir. The Prince of Yan, Zhu Di, raises an army under the banner of "clearing the sovereign of evil ministers," launching the Jingnan Campaign and seizing the capital Yingtian. Facing his father, Zhu Di declares that the aging emperor must step aside, while his young nephew accuses him of treasonous usurpation—to which the Prince of Yan replies that the throne is a burden the boy cannot possibly bear.
