As the flames of the Jingnan Campaign erupt, Shen Chengze transmigrates to the final years of Jianwen’s reign. He predicts the surrender of Jinchuan Gate and earns Zhu Di’s favor with a strategy to secure the city. Using his modern financial expertise, he revitalizes the Ming economy; agricultural innovations fill the granaries; and firearms, ironclad ships, and a powerful navy expand the empire’s maritime frontiers. Amid the clash between the crushing weight of imperial authority and the legacy of Confucian traditions, he advances cautiously, building a prosperous and powerful nation and helping the Yongle Emperor usher in a golden age far greater than anything recorded in history.
