A legend of faith that spans the flames of war, a life-and-death spy battle in the airwaves**
**Introduction:**
In 1935, during the artillery fire after the fall of Peiping, Xu Jiashu, a physics student at Yanjing University, witnessed his home being shattered and his father arrested. He accidentally inherited half of a code manual and an unfinished anti-Japanese contact map. From then on, he stepped into the secret front and grew from a young student to a "double-faced ghost" wandering the intelligence networks of the country, the Communist Party, and Japan.
In the army, he improved radio stations and deciphered secret messages, only to discover that the commander he was loyal to was actually a spy codenamed "Ginkgo";
In the underground party, he met the female agent **Cheng Yuqing**. The two went from testing each other to sharing life and death. During the darkest moment of the Nanjing Massacre, they made a bloody and tearful accusation to the world;
When his father's "List of Stars" revealed the truth about high-level treason, and when his most trusted mentor committed suicide in front of him, Xu Jia Shu finally understood: true loyalty never attaches to any party, but only belongs to this suffering land.
**From Peking to Yan'an, from Nanjing to Hong Kong**
He used the code taught by his father to deliver top-secret information, and used the "Nightingale" radio station designed by himself to penetrate the enemy's blockade;
She works as a reporter in high society, but she hides a miniature camera under her cheongsam to record the atrocities of the Japanese army;
When the two found their dying father in Taiyuan Prison, and when the ultimate conspiracy of the "Ginkgo Network" emerged, this secret battle about faith, betrayal and redemption finally ushered in a bloody dawn...
