ZTE Ming Dynasty: Save Lu Xiangsheng at the Beginning

Modern historians accidentally traveled through time and became Emperor Zhu Youjian of Chongzhen. It was September of the 10th year of Chongzhen, one year and three months before the Qing army entered the fortress and Lu Xiangsheng died in the battle with Julu. Relying on his accurate prediction of history, the protagonist completely abandons the original owner's suspicious and stubborn personality weaknesses, and breaks the situation with a strategic vision that transcends the times: he directly rescues Lu Xiangsheng in the beginning, and the imperial commander personally marches to repel the Qing army.
