Shen Ling, daughter of a military family in the Great Shuo, appears to be a timid, bird-fearing wife of the Minister of the Imperial Stud, but secretly commands the Lingqin Pavilion, an intelligence network that uses birds to relay messages and investigate corrupt officials. She and her husband, Pei Zheng, work together in the open and in the shadows to expose the Second Prince's faction for embezzling military pay, trafficking in fine warhorses, and framing loyal officials, clearing her uncle's name. Shen Ling later infiltrates the enemy camp in Western Qiang and burns the enemy army's grain and fodder, helping secure a great victory on the frontier. After recognizing the emperor's suspicions, the couple voluntarily relinquishes control of their intelligence network and receives permission to retire into seclusion. On their way into retirement, they stumble upon clues to an illegal iron-mining operation and a rebellion plot, and join forces once more to protect their homeland. With devotion to their country and a deep understanding of the duties between sovereign and subjects, they embody the strength of a remarkable woman and the righteousness of loyal service.
