Aspire to Yanyun

My name is Lin Huaixin, and I died once. Before I died, I was a history graduate student studying the reasons for the fall of the Sixteen Prefectures of Yanyun. After my death, I became a Han boy who was about to starve to death in Youzhou City. AD 957. It has been twenty years since Yanyun fell. On the street are the hooves of Khitan horses, and above their heads are the Khitan flags. Those with their heads lowered are my tribesmen. Someone told me: Yan Yun will never come back. I know what he said is true - historically, this land was lost for four hundred years. But I also know another thing: Where will Chai Rong make mistakes, in what year will Zhao Kuangyin die, and at what time will the Battle of Gaoliang River collapse? I know where everyone fails. So this time, it's me. ——This is not a story about a time traveler pretending to be a slap in the face. ——This is the story of a man who knows all the mistakes of history and spends his life filling them. [Iron-blooded military struggle + Yanyun battle to the death + brothers' life and death + temple game. No system, no golden fingers, conquer the world with your brain.
