Reborn Sun Chuanting, I Want to Cleanse the Qing Army with Blood in This Life

I died once. In the 16th year of Chongzhen, Tongguan died in battle, and the Ming Dynasty also fell. Again The first time I opened my eyes, I went back to a year ago. This time, I know who's going to stab you in the back The knife knows where food and grass will be cut off, knows when Li Zicheng breaks the city, and knows which way the Qing army went south. In this life, I will kill the Qing army and rewrite everyone's ending. But I didn't expect that the biggest enemy was not outside the pass, but above the court. I never thought that I would become my final comrade-in-arms with my former mortal enemy Li Dingguo. Even though I knew I couldn't do something, I did it. This time, I want future generations to remember that in the Ming Dynasty, there were people who lived towards death.
