Special Forces King Lu Zheng died heroically during a cross-border rescue mission, but his soul accidentally traveled back to the war-torn Anti-Japanese War era. Living in troubled times when mountains and rivers were broken and his compatriots were suffering, he relied on his top-notch modern special warfare literacy and practical experience to form an assassination team codenamed "Dark Blade". The team hides in the darkness and specializes in intelligence collection, precise sniping and killing of enemy leaders, and eradication of traitors. It wanders in the night and on the edge of life and death. Using flesh and blood as blades and loyal souls as shields, they set off a bloody storm on the battlefield behind enemy lines, vowing to cut off the clutches of the invaders, prevent tragic events from happening, and protect this precarious mountain and river with iron and blood.
