Rise in the Southern Song Dynasty

A mechanic who likes being rich and contented, traveled to the Southern Song Dynasty, when the country was strong but the military was weak, and became the guardian of a wealthy businessman's daughter. Just when he was about to enjoy his comfortable life, he was threatened by the eldest lady to make muskets for the court. Because his brother was robbed, he had to fully assist the ambitious and talented Prime Minister Han in cutting down the gold. For this reason, he trained naked soldiers in the cold winter, rode alone to the enemy's country, fought against bandits in the Taihang Mountains, and fought against the golden soldiers under Xiangyang City... During the Lianjin campaign against Mongolia, he defeated Genghis Khan's best cavalry in the world. In the end, the cowardly Song Dynasty successfully rose and became the real most powerful country.
