Training the Southern Song Dynasty

Zhang Liangchen, a guy who only knows how to fight and make trouble all day long, was finally punished by God and became one of the many time-traveling armies. And unfortunately, when Zhang Liangchen came to the Southern Song Dynasty, the Mongolian army was sweeping the world, and he was not able to let the flowers lead the country like many of his time-traveling predecessors. He had no choice but to start from scratch, accumulate strength bit by bit, expand his territory bit by bit, and finally compete with the Mongolian army in the Central Plains. With more people, there is more power, and farming is the greatest. Zhang Liangchen used his modern knowledge to cultivate a huge empire!
