"Zhaohualu: The Hand Across Time and Space" tells the story of an adventure spanning 568 years. In the third year of Jinghe reign of the Dajing Dynasty, the family of Hanlin scholar Shen Yan was framed by the powerful minister Wei Yong, and his entire family was executed. He fled with half of a "Zhaohua" white jade pendant, but was caught in the fire by the jade pendant and was involved in the turbulence of time and space, falling into the Sioux City Museum in 2024.
Modern curator Lin Mo was organizing cultural relics for the "Special Exhibition of the Dajing Dynasty" and unexpectedly met Shen Yanzhi, who was carrying the other half of the jade pendant. One is an ancient scholar who carries a blood feud, and the other is a modern scholar who is deeply involved in the history of Dajing. The broken jade pendant becomes a link between the two generations, allowing them to gradually trust each other amidst suspicion and temptation.
Shen Yanzhi relied on the power of the jade pendant to travel back and forth between ancient and modern times, trying to find testimony that could overturn the case for his family; in the process of helping him, Lin Mo constantly came into contact with the proposition of "whether history can be changed." From the ancient book library in Su City to the old house of Shuntian Mansion, from Wei Yong's copper water leak to the secret of Queen Xiaoxian, the two pursued the truth in the folds of time and space, and also developed a deep bond in the collision that spanned five hundred years.
When the secret of the jade pendant is gradually revealed, they discover that this connection across time and space is not only related to the redress of an unjust case, but also the ultimate understanding of "protection" and "fulfilment" between two souls - love may travel through time and space, but it will eventually become the light that illuminates each other in their respective eras.
