As a field survival instructor and a mountain warfare expert, Rambo's life after retirement is of course not just horse riding, fishing, drinking and watching TV.

　　 In fact, this tough guy with a heart and a heart, who has nothing to do after retiring, dug an underground maze that extends in all directions like a spider web under his farm.

　　 Originally, Rambo dug this tunnel just to vent his extra energy, after all, he is a bachelor. Later, Dora was very interested and often came to help.

　　 Rambo was happy, and simply dug according to actual combat, and set aside countless traps in the tunnel. Of course, there was no actual installation, just pretending to be for Dora and her friends to play military exercise games in it.

　　 But now, Rambo has activated all those traps.

　　What kind of mines, steel bars, dark arrows...In short, Rambo has installed any damaging weapons. Even ten kilograms of gasoline was hung on the top of the barn, ready to burn the living at last.

　　 When everything is almost done, the sky has gradually darkened.

　　 Rambo stood in the window at the top of the barn, looking up at the sunset in the sky. Under the bright red sunlight, he clearly saw five black SUVs galloping from a distance.

"coming!"

　　 Rambo turned over and jumped out of the barn, and quickly ran into the tunnel. From the reserved observation hole, staring at the movements of the SUVs.

　　 Those five SUVs knew that they couldn't hide their tracks on this endless plain. So when they got off the highway, they immediately spread out, forming a semi-encircled circle, and pressed towards Rambo's farm.

　　 But Rambo was prepared.

　　 When these vehicles were about to rush into the farm, Rambo pressed the detonator in his hand severely. In an instant, two fire dragons, one from the left and the other from the right, suddenly rose up, forming a wall of fire with lightning speed to protect the farm.

　　 Those SUVs were unprepared, a car rushed too fast and plunged into the fire wall. Under the wall of fire was a layer of trenches that had been covered. The wheels plunged directly into it, and the car and the people burned into a fireball.

　　With the lessons of the previous cars, the four cars behind have slammed the brakes. Looking at the wall of fire in front of them, everyone sighed a little. When they were discussing how to put out the fire, one of the cars found that the wall of fire was not completely enclosed, and there was a gap of about three meters.

　　 The gap was naturally made by Rambo deliberately. He knew that this wall of fire alone could not stop the enemy's invasion. The biggest purpose of this wall of fire is to force the enemy to go through that gap.

　　 so that they can receive the gift that they have carefully arranged in the gap.

　　 Those enemies are not fools either, they didn't squeeze in a swarm of foolish people, but ordered one person to drive and explore the road first.

　　 Then the sad buddy, driving the sad SUV, just passed the gap of the fire wall less than five meters away, and soared into the sky.

　　 "Land mine?"

　　 The remaining people's eyes widened.

what's the situation? Didn’t it mean that the target was just a NIA agent, a female intelligence agent without professional military training, plus a bad old man?

　　 How did you prepare so well that even the mines came out?

　　 The remaining masked militants did not dare to step forward for a while. God knows how many mines are buried inside. So the leader with a ponytail (don't think too much, he is a man) had to contact his superiors for support.

　　 But they are idle, Rambo will not be idle. He had considered this situation a long time ago, so he left countless hidden shooting holes outside the farm.

　　 These masked people were still sitting in the car and smoking cigarettes. Suddenly a gunshot fired and the head of a masked person sitting in the co-pilot exploded.

　　 These masked people are well-trained, and the moment their companions are shot, they can determine the direction of the bullet. While firing back, he quickly got out of the car and used the SUV as a shelter.

　　 It is a pity that their counterattack is destined to fail, not to mention that the shooting hole hidden on the ground is so small that bullets can't be shot in. It's useless to shoot in, because Rambo turned around and ran away immediately after firing the shot.

　　 Two minutes later, there was another shot, and a masked man clutched his thigh and started howling.

　　 The other masked men were shocked, and hurriedly turned their guns, and shot randomly at the empty rear.

　　 "Bring the car over and make a circle!"

　　 Under the command of the ponytail, the remaining three SUVs barely formed a semicircular line of defense. Unfortunately, this is still useless, because Rambo reserved a shooting hole just behind these masked men.

　　 Rambo slowly pulled open the baffle, a pile of sand poured in, and then a fist-sized hole appeared in front of him.

　　 He leaned forward to take a look, and he happened to see a huge buttocks twisting at himself.

　　 Rambo's cheek twitched slightly, and slowly pushed the muzzle into the shooting hole without aiming, and directly pulled the trigger.

　　 With a scream of "Woo", the poor masked man, like a toad, first jumped two meters high out of thin air, and then stuck his head on the ground without moving.

　　Only his high-puffed part, like a fountain, is spraying blood out.

"underground!"

　　 Ponytail roared, and simply inserted the gun into the hole of the eye and squeezed the trigger frantically.

　　 But Rambo was tempered from the Vietnam War, knowing the truth about changing a place with one shot, and immediately moved after firing a shot.

　　 Ponytail also knows that this is of no use at all, but if he continues to stay here, he can't escape the fate of being shot.

　　 The only line of defense is to rush in, find the tunnel entrance, enter the tunnel and fight the enemy in street fights~lightnovelpub.net~Although that is also very dangerous, it is better than it is now.

　　 After all, the ponytail is also afraid that he will become the next person who gets enema with a gun.

　　 Abandoning the injured companions, the remaining twelve masked men climbed into the car in embarrassment. Regardless of the mine ahead, he rushed in through the gap in the wall of fire abruptly.

　　 In fact, they really think too much. No matter how good Rambo is, it is impossible to transform his farm into a minefield. He has two mines in his hand, one used in the gap and the other in the tunnel.

　　Actually, Rambo wanted to lead the enemy to fight him in a tunnel battle, so when the three SUVs rushed to his residence, he lifted the plank at the tunnel entrance and leaned out half of his body to shoot at the enemy.

"over there!"

　　 The SUV turned around and rushed to the vicinity of the entrance. More than a dozen big men filed to get out of the car, lifted the plank very professionally, threw a stun bullet in it, and rushed down.

　　 It's a pity that they are professional, and Rambo is even worse than them.

　　 The first buddy who explored the way, just walked halfway down the wooden ladder, and suddenly a wooden plank full of steel nails ejected, and it happened to be caught between the buddy's legs.

　　 Amid the screams, the man rolled down holding the wooden plank nailed to him, and fell into the sinkhole below without a sound.

　　 The ponytail behind wiped his cold sweat, and continued to urge his hands to rush in. The people behind didn't dare to rush forward, cautiously, step by step, tentatively down.

　　 entered the tunnel and walked forward more than ten meters. After no accident happened, a masked man in the lead just wanted to breathe a sigh of relief.

　　 There was a muffled noise suddenly, and a crossbow arrow flew out from nowhere, just piercing his neck.
