1941, Shanghai Concession.
Ling Chen, who worked in the Archives Section of the Japanese and Puppet Intelligence Service, was recognized by the entire agency as a "trash" - he could break a teacup when handing documents, he could stutter from nervousness when reporting, and even the watchdog of the Secret Service Section would bark twice when he saw him.
No one knows that this "coward" who doesn't even dare to step on ants has poison-quenching silver needles hidden in his cuffs and top-secret passwords in the pocket of his pocket watch. No one knows that his codename is "Breaking Dawn" and he is the hidden ace of the military command who scares the Japanese invaders!
When Japan's Special High School was about to attack the underground party "Nightingale", Ling Chen deliberately knocked over the coffee and wetted the arrest list, stalling for time with a stuttering tone: "T-Taijun... This, this document... I, let me check it again?"
When the mole "Venom" tried to pass on false information, he pretended to organize files, but tapped his fingertips on the table in Morse code to pass the real news to his contact.
A certain operation was exposed, and the moment the gun was pressed against his temple, Ling Chen activated the system to rewind for 10 seconds, grabbed the gun with his backhand and pressed the enemy against the wall. His cold eyes were different from usual: "The game is over."
From the Archives Department to the Special Higher Education Course, from Shanghai to Nanjing, Ling Chen danced on the tip of a knife, dealing with lies. Not only does he want to find out the insiders in the military system, but he also wants to smash the Japanese army's "Sakura Project", and he also wants to protect the newsboy girl who always secretly stuffs him sweets in troubled times...
Dawn is approaching, the hidden dragon is out to sea, this darkness should be broken by my own hands!
