Li Liangliang, a senior history student at Tsinghua University, accidentally traveled to the ancient Ming Dynasty and became Emperor Jianwen Zhu Yunwen when he took the high-speed train through a tunnel when he returned from vacation in 2025 for the New Year. After waking up, Li Liangliang discovered that this was the first year of Jianwen, and he was familiar with historical knowledge. I know that in the 4th year of Jianwen, King Yan Zhu Di raised troops on the pretext of "Qing Jun's side" and launched the "Jingnan Campaign". In order to avoid the historical event of "Battle of Jingnan" from happening, Li Liangliang used modern knowledge. After the successful implementation of the policy of reducing the number of officials, Zhu Di's rebellion failed, creating a prosperous era of Jianwen.
