Qin Tianheng had just been promoted to deputy general of the Forbidden Army due to his military exploits in northern Xinjiang and was transferred to the Forbidden Army in the capital. He was ordered to follow his superiors to participate in the seizure of Taifu Weiguang's mansion. Wei Guang was framed for being involved in a princeling feud, and his whole family was investigated. When Qin Tianheng was searching a remote courtyard, he came across the concubine Wei Nanxing hiding in the woodshed trying to escape. He originally wanted to hand her over as a "remnant", but he was attracted by her unique fragrance. A strong physiological dependence drove him to temporarily change his mind and take Wei Nanxing back to his house as his wife. The heroine was forced to pretend to agree, and then actively started to save herself. Qin Tianheng was also involved in the thrilling palace struggle. After a series of events, the two finally understood each other.
