Chengfeng: the History Books Are Unknown and I Wrote Them Myself

In the seventh year of Chongzhen, there was a carriage gorge. Forty thousand rebels were trapped in a desperate situation, and history books determined that the entire army was annihilated. Ren Chengfeng, an undergraduate student in the Department of History, fell off a cliff and traveled across the cliff, holding all the answers to this period of history. He fought with the thirty-sixth battalion and entered the governor's residence alone in order to break the deadlock. If there is no name in the history books, then I will write the history with my own hands!
