Jia Bin, a modern-day ace soldier, unexpectedly transmigrates into an occupied zone in 1938 during a mission, becoming a puppet-army squad leader despised by everyone. Faced with the Japanese army's brutality and his countrymen's suffering, the soldier's faith etched into his bones leaves him unable to submit: with a blade at his throat, he would rather die than surrender; he goes undercover in disguise only for his country and people.
Branded a traitor, he walks a knife's edge: he pretends to carry out the Japanese army's “pacification” campaigns while secretly helping resistance supporters escape; he appears to train the puppet troops while covertly building anti-Japanese forces; he makes secret contact with the underground Party and uses his modern military knowledge to pass on vital intelligence, helping guerrillas seize food, destroy munitions, and break encirclements.
From squad leader at a stronghold to a puppet official in the county seat, from the secret police's torture to Japanese agents' tests, Jia Bin uses courage and cunning to navigate enemy territory. He persuades wavering collaborators to defect and eliminates die-hard traitors, weaving a secret resistance network across the occupied zone. He has seen comrades fall before dawn and heard his countrymen curse the “puppet army,” yet he continues to endure the stigma of “pretending to sell out his country” as he honors his vow to “truly resist Japan.”
When the bugle sounds for the counteroffensive, he leads the troops who have switched sides in tearing through Japanese defenses, washing away every stain on his name with blood. From ace soldier to infiltrator, from puppet soldier to resistance commander, Jia Bin's journey is a singular, battle-forged legend from an age of war: though trapped in the abyss, his heart turns toward the light. With solitary courage, he protects the land and its people.
