I Became the Regent of the Song Dynasty

Ding Jiazhou was defeated, and I became the number one scapegoat of the Song Dynasty. I was shocked to realize that I had traveled through time with the knife on my neck. I disrupted the Mongolian camp with a false letter, changed my destiny against the will of the Song Dynasty and Mongolia, recruited famous generals, fought against powerful ministers, and took control of the military. Finally, I launched the Northern Expedition, and single-handedly extended the fate of the Song Dynasty against the heavens!
