General Zhenxi died on the battlefield. There was a severe drought in the western border, and there was no harvest. The enemy took advantage of the opportunity to attack. The general's daughter {Su Linshuang} took over the power in a critical situation, but found that the army rations had been embezzled by the deputy general Wei Kun, leaving the soldiers hungry and weak and the people displaced. Gu Yanchen, the imperial censor sent by the imperial court, initially suspected that she was a woman unable to take on such an important task, but he saw that she used military tactics to deploy defenses, open warehouses to help the people, and train troops to defend against the enemy, and managed to sustain the crisis in the western border. Facing Wei Kun's betrayal, the spread of the epidemic, and the enemy's fierce attack, Su Linshuang used iron-blooded means to maintain military discipline, resist natural disasters, and repel enemy troops. She even joined forces with Gu Yanchen to support the people of the Western Region in the famine and write a legend of a female general guarding the mountains and rivers.
