A car accident that traveled through time and space caused Lin Yue, a modern workplace elite, and Su Qing, a descendant of a family of traditional Chinese medicine, to fall into the Forbidden City in the 28th year of Qianlong's reign with the knowledge and memories of the 21st century. They replaced the troubled Xiao Yanzi and the talented Ziwei, but under the nine-story glazed tiles of the Qianqing Palace, they set off an innovative storm that subverted the era.
Lin Yue used martial arts and modern thinking to break through the situation, and used the "Qing Dynasty Logistics Network" to break down trade barriers, allowing Qianlong to face the people's livelihood hardships; Su Qing used traditional Chinese medicine anatomy to revolutionize the Imperial Hospital, and used artemisinin to save people from the plague, but she fell into a life-and-death crisis because "a female doctor was involved in witchcraft". They worked hand in hand on the road of reform, but they were also shocked at every step because they touched the foundation of imperial power.
When the secret came to light, Qianlong stamped the paternity test with a jade seal, and when Su Qing's manuscript turned yellow and was stained by Erkang's ink... They finally found themselves caught between imperial power and civil rights, lighting up the night sky of the Qing Dynasty with the light of modernity.
However, the flow of history never turns back - should we choose to forget our mission and stay in the Forbidden City, or should we choose to return to modern times with our memories? This two-way redemption spanning three hundred years has long transcended the love between children and has become an eternal dialogue between two generations on freedom and change.
