The Liang Kingdom under the Liuli Dynasty was originally a powerful country among the three kingdoms of Liang, Chen, and Wei, but successive years of natural disasters had damaged its national power. Minister Qi Qiu advocated reform. The king of Liang was secretly pleased that he could seize the land of the hereditary nobles. At the same time, in order to check and balance the various forces in the court, Qi Qiu was wronged and imprisoned. Qi Qiu suffered from asthma. The person who falsely accused Qi Qiu was Minister Lang Xiong.
Qi Qiu's daughter Qi Man fled with her younger brother overnight and was hunted down by Lang Xiong's eldest son Lang Qi, the sworn enemy of the Qi family. Lang Qi recognized Qi Man as the clever and outspoken woman who had helped him at a certain minister's birthday party. At the moment of the lightning and thunder chase, when Lang Qi took back his bronze sword from Qi Man, he traveled to modern times.
The two have different goals. In order to survive in the modern world, Lang Qi teaches swordsmanship, while Qi Man is spotted by You Qiaomu, the owner of a brokerage company, because of his classical charm. Both of them felt that finding each other was the key to going back, so they each demonstrated special skills brought by ancient times in the live broadcast room: Lang Qi's Qinggong, Qi Man's "circle dance" to expel ghosts.
After a series of events happened, they unexpectedly returned to ancient times. The place they settled in was a forest full of ghosts and wars between several countries were about to begin.
They used modern technology to stop the impending war in time. Qi Qiu was also released because of Qi Man's meritorious service, and he recovered after taking the hormones for treating asthma that his daughter brought back from modern times. Lang Qi and Qi Man became friends of the Qin and Jin Dynasties, and together with You Qiaomu, who loved ancient times, they used modern technology to benefit ancient people.
Intention: After traveling to modern times, the two people did not linger in the prosperity. After accidentally traveling back to ancient times, they used modern technology to benefit the ancients.
