Gao Lingjun, the daughter of the commander of the Military and Horse Division in the capital, learned martial arts from a famous teacher since childhood. He is as beautiful as a lotus, dazzling as a pearl, polite and dignified, and deeply loved by his grandparents. At present, the capital is a mixed bag. With the entry of rogue parties and illegal personnel, various cases occur frequently. Gao Lingjun transforms into a man in black at night to help Li Changjun, a royal guard, capture the key criminal and let him perform meritorious deeds. When homicides and arson cases occurred in the capital, Gao Lingjun captured criminals several times at night in order to prevent his father Gao Yan from being censured by the Inspectorate.
Li Changjun lost his father when he was young and was raised by his mother Dou Lanzhi. Later, he became a disciple of Wudang Taoist Yuan Xin and became a Jinyiwei at the age of nineteen on the recommendation of Gao Yan. Later, Master Yuan Xin was killed at the hands of evildoers, and Gao Lingjun unintentionally avenged him.
Li Changjun's grandfather was a descendant of an anti-Japanese general, and he had been friends with Gao Lingjun's grandfather for many years. Under the control of the two old men, the two finally got married.
