As a field survival instructor and Mountain Warfare expert, Rambo's life after retirement is certainly not just riding, fishing, drinking and watching TV.

In fact, the tough old man, who had nothing to do after retirement, dug up an underground maze extending in all directions like a spider's web under his farm.

Originally, Rambo dug this tunnel just to vent his excess energy. After all, he is single. Later Dora was very interested and often came to help.

As soon as Rambo was happy, he simply dug according to the actual battle and reserved countless traps in the tunnel. Of course, there was no real equipment, just pretending for Dora and her little friends to play military exercises in it.

But now Rambo has enabled all those traps.

What mines, steel bars, hidden arrows... In short, Rambo has installed all kinds of insidious and poisonous weapons. Even ten kilograms of gasoline were hung on the top of the barn, ready to burn people alive.

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

Rambo stood in the window at the top of the barn and looked up at the sunset in the sky. In the bright red sun, he clearly saw five black SUVs speeding from a distance.

"Coming!"

Rambo jumped out of the barn and ran into the tunnel. From the reserved observation hole, keep an eye on the movements of those SUVs.

The five SUVs knew that their tracks could not be covered up in this endless plain. So when they got off the road, they immediately spread out, forming a half bag encirclement and pressing on Rambo's farm.

But Rambo was on guard.

When the vehicles were about to rush into the farm, Rambo pressed the detonator in his hand. In an instant, two fire dragons, one on the left and one on the right, suddenly soared, 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. There was a covered trench under the fire wall. The wheels fell directly into it, and the car and people burned into a fireball.

There was a lesson from the past, and the four cars behind slammed on the brakes one after another. Looking at the fire wall in front of them, they were a little disappointed. When they were discussing how to put out the fire, a car found that the fire wall was not completely enclosed and there was a gap of about three meters.

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

In this way, they can receive the gifts carefully arranged at the gap.

Those enemies were not fools. They didn't rush past in a swarm of fools, but ordered one person to drive to explore the way first.

Then the sad man, driving the sad SUV, just passed through the gap of the fire wall not five meters away, and soared into the air.

"Mines?"

The rest opened their eyes.

What happened? Doesn't it mean the target is just an NIA agent, a female intelligence agent without professional military training, and a bad old man?

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

For a time, the remaining masked militants dared not come forward again. God knows how many mines are buried inside. So the leader with a ponytail (don't think much, he's a man) had to contact his superior for support.

But they're idle. Rambo won't be idle. He had long considered that this would happen, so he set aside countless hidden shooting holes outside the farm.

These masked people were still smoking in the car. Suddenly, a gun rang and the skull of a masked man sitting in the co pilot burst open.

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

Unfortunately, their counterattack was doomed to fail, not to mention that the firing hole hidden on the ground was very narrow, and the bullets could not be shot at all. It's no use shooting in, because Rambo immediately turned and ran away after shooting.

Two minutes later, there was another gunshot, and a masked man covered his thigh and howled miserably.

Other masked people were shocked, and hurriedly turned the muzzle of the gun and fired indiscriminately at the empty rear.

"Drive the car and circle!"

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

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

He leaned forward and saw a huge hip twisting at himself.

Rambo's cheek twitched a few times, slowly pushed the muzzle into the shooting hole, didn't need to aim, and pulled the trigger directly.

With a scream of "ow", the poor masked man, like a toad, jumped up two meters out of thin air, and then stuck his head on the ground.

Only his high pouting part, like a fountain, is puffing out blood.

"Underground!"

The ponytail roared and simply inserted the gun into the hole and pulled the trigger madly.

But Rambo was tempered from the Vietnam War. He knew the truth of changing a place with one shot. He moved immediately after firing the gun.

Ponytail also knows that he has 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 entrance of the tunnel, enter the tunnel and fight in the street with the enemy.

Although that is also very dangerous, it is better than being shot in the cold.

After all, ponytail is afraid of becoming the next person to be shot ~ in the intestines.

Abandoned his injured companion, the remaining twelve masked men climbed into the car in some confusion. Regardless of the mines in front, he rushed in through the gap in the fire wall.

In fact, they really want more. No matter how good Rambo is, he can't transform his farm into a mine array. He had two mines in his hand, one in the gap and the other in the tunnel.

In fact, Rambo wanted to lead the enemy to fight a tunnel battle with him, so when three SUVs rushed to his residence, he opened the board at the tunnel entrance, leaned out half of his body and shot the enemy.

"Over there!"

The SUV turned around and rushed near the entrance. More than a dozen big men got out of the car, opened the board professionally, threw a vertigo bomb into the car, and then rushed down.

Unfortunately, they are professional, and Rambo is worse than them.

The first man to explore the way just walked half down the wooden ladder. Suddenly, a board full of steel nails was ejected and buckled between his legs.

In the shrill scream, the man rolled down with the board nailed to himself, and fell into the pit below without a sound.

The ponytail at the back wiped the cold sweat and continued to urge his hands to rush in. The people behind did not dare to rush forward rashly. They walked down cautiously and tentatively step by step.

After entering the tunnel and walking more than ten meters forward, there was no accident. A masked man in the lead just wanted to breathe a sigh of relief.

Suddenly, there was a dull clank, and a crossbow flew out of nowhere, right through his neck.
