The Dark Blade of Qi Men

During the peaceful period of Song and Liao Dynasties, Tang Ziyan, an agent originally trained by the secret organization "Phoenix Fire Army", was assigned to serve in the Imperial City Department of Kyoto. When she wanted to retire and spend her life with her husband Zhou Qianan, her husband was kidnapped by the Phoenix Fire Army and coerced. Tang Ziyan was given a new task: to assassinate the visiting Northern Dynasty envoy Huang Taidi. During this period, before Zhou Qian'an was shot and killed by Feng Huo Army, Tang Ziyan was determined to overthrow Feng Huo Army, pretending to be unmoved and continued to delve into the next step of the assassination plan, but was surprised to find that the contact person was actually beside him. In the end, Tang and the emperor's brother worked together to narrowly defeat the Fenghuo Army, quelling the chaos and returning peace to Kyoto.
