A modern history college student traveled back in time and became King Li Chuang, who was about to die with only two months left in history. He was familiar with history and decided to use his life to do something for the entire Han people so that the Han people would no longer fill in the history of sorrow and humiliation. So he captured Beijing, issued an order to eliminate the invaders, and fought a bloody battle with Dorgon in the Shahe River. History eventually changed because of him, and the Manchu Qing Dynasty died in the late Ming Dynasty.
