The modern elite accidentally traveled to the last years of Hongwu and became the companion/clan minister of the emperor's grandson Zhu Yunwen. Relying on his accurate prediction of the direction of history and his insights beyond the times, he skillfully dealt with the pressure of Emperor Hongwu in his later years and established deep trust with Zhu Yunwen.
When Emperor Jianwen ascended the throne, the discussion of reducing the vassal vassalage suddenly arose. The protagonist is well aware of the cruelty of the Battle of Jingnan and Zhu Di's ambition, and tries to guide Emperor Jianwen to adopt a more prudent strategy. However, Huang Zicheng, Qi Tai and other close officials are stubborn and the crisis is imminent. King Zhu Di of Yan boldly raised troops in the name of "Qingjun side", and the war raged across the north.
In times of crisis, the protagonist steps forward and uses modern military thinking and organizational skills to assist Emperor Jianwen in stabilizing the situation and turning the tide. From passive response in the early stage to proactive attack, he gradually reversed the situation of the war, defeated the Yan army, and preserved Jianwen's country.
After Jingnan was pacified, the protagonist assisted Emperor Jianwen in launching comprehensive reforms. He rectified the civil service, innovated the military, developed the economy, opened up the sea for trade, promoted science and technology, and enlightened the people's wisdom. The Ming Dynasty, which had many shortcomings and was on the verge of splitting, was gradually built into a new dynasty with a prosperous country, a strong people, a prosperous country, and a prosperous culture. It created a glorious era of "Jianwen New Deal" and eventually left a name in history, becoming a legendary minister of a generation.
