Ling Weilan, an orphan girl from the Zhenbei Hou Mansion, grew up in the military camp with her father and brother. At the age of fifteen, she changed her name to "Ling Lan" and went to war on behalf of her brother. With her original tactics, she defeated the barbarians and was awarded the title of "Polu Captain". However, after her father and brother died in the war, the imperial court took away her military power on the grounds that "women should not be in charge of the army" and forced her to marry the son of a dandy relative. Ling Weilan faked her death and escaped on the eve of her wedding, hiding among the people to secretly contact her old subordinates. Three years later, the northern border was in crisis again, and no one was available in the court. Zheng Chang (a secret prince, with the pseudonym of the army), who had a battlefield agreement with her, designed to help her return to the military camp as a counselor. While using her resourcefulness to solve the food crisis and repel the barbarians, she exposed the court's conspiracy to frame Zhongliang. In the end, her illustrious military exploits forced the court to abolish the old rule that "female generals are not allowed to be ennobled", which not only protected the peace of the family and country, but also broke free from the prison of fate.
