In the late autumn of 1931, in the bloody snow of Fushun, Chen Yan, a doctor of military history archives and a restorer of anti-Japanese war cultural relics, suddenly traveled through time.
He does not have the fighting skills of a special force, nor the invincible golden finger that creates things out of thin air. The only thing he relies on is the Japanese army's declassified files that are half right and half wrong, and a pair of hands that can repair scrap metal into standard firearms.
The smoke of September 18th has not yet cleared, and the Northeast has already fallen. The powerless scholar bumped into Wang Tieshan, a veteran of the Northeast Army who was cornered by the military order of non-resistance, and rescued Lin Mo, an underground party intelligence agent who was betrayed by a traitor. Three desperate people lit a lonely lantern of resistance against Japan on the abandoned black land.
Mistakes in the files pushed them into desperate situations again and again, and the encirclement and suppression of Japanese ace Ishihara Shinji was pressing harder. From desperate survival in mountain villages to a full-scale counterattack during the 2014 war, they made up for the regrets of history with their own flesh and blood, defended the bottom line of their home and country with their bravery, and carved their names into the everlasting history of the Anti-Japanese War.
