Southern Song Dynasty 1276

Accidentally traveling through 1276, the situation in the Southern Song Dynasty was already very critical. Boyan was about to conquer Lin'an, and the Song Emperor was anxious and wanted to surrender. This is a tragic era with indescribable painful memories. When the Mongolian cavalry trampled the great rivers and mountains of the Southern Song Dynasty, the court did not resist, and the people of the Song Dynasty could not sit still and wait for death. They had no other choice but to resist. I traveled through time and became Zhang Yun, the son of Sichuan Zhizhi Zhang Yu, and became a soldier with a transformation system. Let's see how I can turn things around, kill the Tatars, and return our mountains and rivers. Military system: Xiang has jurisdiction over 10 armies, the army has jurisdiction over 5 battalions, and the camps have jurisdiction over 5 capitals. 100 People each.
