The background of the story is set in an imaginary dynasty, the Yue Dynasty, which was an era of divided nations. There were the neighboring ethnic minority regimes of Liao, Jin, and Xia surrounding the Yue Dynasty, and the Liang Dynasty, which was also a Han regime. Ling Nanqi was born in a Jiangnan family. His father, Ling Xuanxing, was a general in the imperial court, and his brother Ling Nanyuan served in the army. At that time, the Liao and Jin coalition forces raided the border, and his father and brother were sent to the border. He thought that just like before, he would receive news of his father's victory soon, but one day he suddenly received his father's suicide note. He rushed to the battlefield, but the war was already over. In Liang State, Zhou Heng's life also changed from a flag official.
