This secret letter, which contained information about the revolutionary experiment, turned out to be the key to the continuation of their relationship in this life.
During the Republic of China, Su Li, the daughter of a warlord, and Gu Chenzhou, a revolutionary strategist, fell in love but could not stay together. She concealed the righteousness of her family and country in her love letters, and secretly conveyed revolutionary information. As the war raged, he was buried in the revolution, and she never married. This forbidden love sank into the long river of history along with the secret letters.
A hundred years later, antique restorer Su Li accidentally obtained a yellowed love letter and asked for help from cryptographer Gu Chenzhou. At the moment of deciphering, Gu Chenzhou's heartbeat accelerated wildly - and what was even more outrageous was that a love letter suddenly appeared in the middle of the letter, and it was clearly signed by his name.
Purpose: Emphasis on the tenacity and great power of love across time and space, embodying the mystery and irresistibility of fate. In addition, the interweaving of history and reality allows readers to appreciate the weight of history.
