Lin Hai Tian Defense Silent Blade

Deep in the vast forest sea of ​​Daxing'an Mountains, the world can only see the steel army on the parade ground, but they don't know that there is a top-secret defense system hidden in the clouds and mist in the northern border of the motherland. Recruit Jiang Lei stepped into the border duty platoon and followed veteran platoon leader Zhao Feng to patrol the boundary markers day after day. From the confrontation on the narrow road in the valley on a rainy night, to the clearance of cross-border criminal dens in deep mountain caves, from guarding the border alone in the cold winter snow, to the head-on defeat of the raid by overseas special forces, Jiang Lei gradually lost his youth and understood the true mission of the border guards: holding a sharp blade is to stop the war, and concealing natural defense is for peace. Generations of border guards have taken root in the wilderness with their flesh and blood. The powerful weapons are hidden in the clouds to intimidate all directions. Mortals guard the mountains and rivers, and the sky protects their home and country. Together they build a national border barrier that will never fall.
