Lin Mo, a college student in the history department, woke up and traveled to Shanghai in 1937 on the eve of the Songhu Battle. His identity is a student of the same name at St. John's University, and his father is an underground party liaison. He mysteriously disappeared after leaving a pocket watch engraved with "Daybreak" and an encrypted suicide note.
In order to find his father's trace and survive, he was forced to step into the shadow world, using his student identity as a cover to deal with the Japanese invaders, the military command, the underground party and the Wang Puppet regime. He is a "suspicious scholar" in the eyes of the special high school, an "unpredictable variable" in the eyes of the military commander, and a "comrade with secrets" in the hearts of the underground party.
From the neon lights of the Shanghai Concession to the ancient book bookstores in Nanjing City; from the radio station in the Chongqing air raid shelter to the ice fields of the Puppet Manchukuo 731 Base. Lin Mo used modern cryptography to crack secrets, used historical predictions to reverse the deadlock, and used carefully planned "performances" to complete a fatal lurk in the heart of the enemy. And the pretty daughter Shen Qingyue who always appears at critical moments, is she a monitor sent by the military commander, or is she a life-or-death partner who can be trusted to support her?
When the love between father and son, the righteousness of family and country, the love between sons and daughters and the path of faith fiercely collide, and when the truth of the "Dawn" project and the mystery of his father's sacrifice are gradually revealed, Lin Mo finally understands: The mission of a time traveler is not to watch history, but to be the beam of light that pierces the darkest night. This is the ultimate spy war across time and space.
Using knowledge as a blade and faith as a shield, we will fight for the survival of the nation in the gaps of history.
