The Southern Song Empire

After a medical accident, Zhao Bing fell down a flight of stairs and transmigrated into Zhao Gou of the Southern Song dynasty. After searching the mountains and scouring the seas, Zhao Bing promptly gave up on sailing south and landed at Taizhou, where he organized his troops to hold the Huai River defense line. He then drew on the history he had learned in the modern era to reform the Song dynasty's three redundancies and two abuses, strengthen control over and the standing of the army, and appoint civil and military officials from the war faction, including Li Gang, Zhao Ding, Yue Fei, Han Shizhong, Wu Jie, Wu Lin, and Liu Qi. He stockpiled supplies and trained the army, then conquered the Jin, marched south to destroy Dali, and west to destroy Western Xia, building a mighty Song Empire.
