In the troubled times of the Eastern Wei Dynasty, the imperial power fell away. The great Sima Gaocheng was hypocritical and manipulated power. He framed Xue Wei, the commander of the imperial army, for collaborating with the enemy Rouran, and the entire Xue family was exiled. The youngest son Xue Liang went to Shazhou to serve as the chief historian as a guilty person, shouldering the important responsibility of clearing wrongs and guarding the border.
Shazhou is surrounded by crises, the governor Yu Wenxing is imposing excessive taxes, Gao Cheng's spy organization is infiltrating and lurking in Shuiyunjian, and Rouran's cavalry is watching eagerly. Xue Liang became brothers with Chang Huaiyu, a border general on the way, and received help from Wang Zhenyuan, an old member of the Xue family, to rectify the official administration and control the military power.
Su Qingyi, a childhood sweetheart, turned into a traveling doctor and came with medical skills and intelligence; Wang Ruotong, the daughter of the Minister of War, was angry at her father for clinging to powerful people, and after the breakup, she became Xue Liang's advisor with military strategies. Princess Yuan Le of Wen Le met Xue Liang due to an attack on the border. She fell in love with his integrity and took the initiative to help as a princess, never becoming a pawn.
Xue Liang stood side by side with everyone, fighting fiercely with Rou Ran on the battlefield, fighting wits with superiority in the court, disintegrating the water and clouds in the dark network, and finally clearing up the Xue family's injustice. After his success, Xue Liang declined the generous salary offered by high-ranking officials and returned to Shazhou. In the end, the war in Shazhou was silent forever, the people lived in peace, Xue Liang and Su Qingyi guarded the border, and Wang Ruotong took charge of the border defense.
