Time Travel into Jianwen? Zhu Di, You Are Finished!

On the tenth day of the fifth month in the thirty-first year of Hongwu (June 24, 1398), Taizu Zhu Yuanzhang died in Yingtian Palace. Zhu Yunwen, the grandson of the emperor, ascended the throne and became Emperor Jianwen. However, Emperor Jianwen's throne faced potential threats from many of his uncles, especially the powerful King of Yan Zhu Di. In order to stabilize his rule, Emperor Jianwen, on the advice of his ministers Qi Tai and Huang Zicheng, began to reduce the vassal status. The King of Yan, Zhu Di, was not willing to sit back and wait for death, so he launched the Jingnan Campaign in the name of "Qingjun's Side". At this critical moment, Zhu Yunwen talked nonsense as if he was suddenly insane, and refused to convene a court meeting, which was suspected of cowardice. It turns out that Huang Shang, who graduated from college, time-traveled into him. So, can Huang Shang, who is familiar with Ming history and a military strategist enthusiast, turn things around as "Zhu Yunwen" and defeat the Yan army led by Zhu Di? And will Huang Shang's arrival bring new glory to this "last dynasty of the Han people"?
