Su Qinghuan, a modern Chinese medicine graduate student, accidentally traveled through the space of an ancestral jade pendant and became the legitimate daughter of the Zhenbei General's Mansion in Daning Dynasty. The original owner committed suicide by throwing herself into a lake because she refused to marry Gu Zhaoheng, who was rumored to have been "treasonous and deposed". In order to protect her family, Qing Huan was forced to marry as a substitute, but she was tortured by officers and soldiers during the escort. She relied on space medical skills to rescue Gu Zhaoheng from death. After the two were exiled to the border, Qing Huan used the space spirit spring to reconnect his veins, used modern medical techniques to help him recover, and conquered the soldiers and civilians on the border with his kindness as a doctor. Gu Zhaoheng secretly contacted the old troops and exposed Emperor Zhao Hong's "treason" conspiracy. The Beirong invasion was actually bribed by the emperor. Three thousand soldiers of the Gu family died unjustly. He had his veins cut, his throat sealed and mute, just to seize his military power. In the end, the two teamed up to rectify the unjust case. Qing Huan helped Gu Zhaoheng ascend to the throne of God, but chose to retreat to the countryside, give up the throne, and stay on the border with her lover, writing fireworks and affectionate daily life of the emperor and empress.
