On an island continent called Dachuan, four countries, Qianjin City, Red Dan Kingdom, Snow Kingdom, and Desert City, stand side by side, as well as more than ten small vassal states. In 1169 AD in Dachuan, the barren desert city went to war with Qianjin City to solve its resource problem. The victorious Desert City brought Qianjin City's only young master back to the desert as a hostage on a twelve-year agreement, and Qianjin City had to pay tribute in huge amounts of various materials every year during these twelve years. To ensure the safety of the hostages. Encouraged by Desert's move, the Red Dan Kingdom also invaded the Snow Country on a large scale in the summer of 1170 AD. They fought for fourteen months and finally occupied the Snow Country's territory. Four years after the young master of Qianjin City was taken to the desert as a hostage, General Yuan Yufei of the Jingtian Department of Qianjin City, who had planned for a long time, killed the leader and established himself as the master of the Jingtian Department. Qianjin City suffered too much losses in the war, and the large amount of materials it paid to the desert every year caused Qianjin City's treasury to be in deficit and unable to conquer the Jingtian Department. He had to be recognized as the leader of the Jingtian tribe. And in the Snow Kingdom occupied by the Red Dan Kingdom. Because the Red Dan Kingdom imposed brutal taxes on the people of the Snow Kingdom, it aroused the resistance of the hot-blooded elements of the Snow Kingdom.
