"Some histories should not be forgotten, and some truths must be buried."
Genius antique restorer Zhou Qinglan received a broken lacquer box from a mysterious man Qi Mo on a rainy night. When he touched it, fragments of memories of the Republic of China flashed out. When she accidentally triggered the mechanism during the repair process, she and Qi Mo traveled to Ningcheng in 1925 and discovered that the famous theater actress Zhou Manqing, a woman with the same appearance as her, was involved in a spy war involving the fate of the country.
As the investigation deepened, Zhou Qinglan was shocked to discover that Zhou Manqing was her great-great-grandmother, and she was actually the "intelligence container" that was sent to the future.
The antique box contains key evidence of the Japanese military's germ warfare, and various forces compete across time and space.
The "Guardian of Time" organization to which Qi Mo belongs strictly prohibits changing history, but Zhou Manqing's death in three days is a foregone conclusion.
When a cultural relic restoration knife meets a space-time weapon, when blood and family ties collide with the torrent of history - how to choose between saving one person and protecting billions of living beings?
