In the Shanghai Concession, programmer Chen Guanchao spends all his time with a typewriter and telegraph codes. When the July 7th Incident broke out and war swept across the country, he accidentally intercepted a secret message from the Japanese army.
The military commander forced him to decipher the code on the charge of collaborating with the enemy. He jumped into the Huangpu River during his escape, hanging on by a thread. On the occasion of life and death, he unexpectedly received a golden finger.
You can see the afterimages of characters reorganizing in the air, deduce the laws of secret electricity, and predict the enemy's movements. Code becomes a weapon and logic becomes a shield.
He used algorithms to set traps, write passwords, counter-track, and disrupt the Japanese military's communication network. Others rely on guns and cannons to fight, but he relies on his thinking to win a thousand miles.
In the intelligence network behind enemy lines, he became the most hidden and deadly existence. The Japanese secret service was furious and wanted this invisible enemy throughout the country.
From foreign companies in the concession to cave dwellings in Taihang Mountain, from Sihang Warehouse to the surrender ceremony in Nanjing. He will eventually rewrite the outcome of the entire war with one line of code.
