In 1939, Pei Heng, the youngest cryptographic genius in the military, woke up and found that he had become a sleeper in Telecommunications Office 76.
The headquarters was bloodbathed, the files were destroyed, and the contact person disappeared - no one knew his true identity. The enemies regarded him as one of their own, and the comrades regarded him as a traitor.
And his only weapon is all the predictions of future intelligence wars in his mind. Who will be the next top agent to be caught? Which top-secret telegram is enough to turn the tide of the war? He wandered between the interrogation room and the code book, dancing on the tip of the knife every second.

When the layers of multiple identities were peeled off, the entire Far East intelligence network was trembling at his fingertips - this name forgotten by history was about to rewrite the course of the war in the dark.
