Ye Shuang, the daughter of a general, fell in love with a counselor from a poor family. They fell in love with each other at the border, but they were separated due to the turmoil in their home and country. Four years later, Ye Shuang guarded the border with the hatred of the country and family, while Shen Ji rose to prominence in the court. The two of them, one on the battlefield and the other in the court, thousands of miles apart, using the mountains and rivers as a chessboard and letters as a link, worked together to clear the court and repel foreign enemies. In the end, they stood side by side to see that the mountains and rivers were safe and guarded together.
