The enemy has concentrated a large number of various aircraft here, and the protection is naturally very tight.

Looking down from this hill five kilometers away from the airport, you can see that there are barbed wire mesh three kilometers around the airport. At the same time, there are warning signs with landmines buried in many places, and soldiers patrolling back and forth, with a very high alert.

On the other hand, he also saw four air defense positions at the beginning and end of the airport. Two were double-mounted air defense guns and two were four-mounted. The calibers should be twenty mm and thirty mm. They were used to fight the United States and the Soviet bombers may not be enough, but they were completely enough to deal with unarmored *********.

Several searchlight cars were parked around the airport to provide air-to-air lighting.

It seems that the other party also knows that there are aircraft in the military sub-district. Although it is an unmanned model aircraft, it still makes some air defense preparations.

Guan Fei was not in a hurry. He first put the radio back into the backpack, then took out a flat plate like an arcade control version and placed it in front of him. He deliberately leveled the ground so that the control version could be placed smoothly, and at the same time, he fixed the board more firmly with clay.

This control board is so similar to an arcade, even the left and right ends have a rocker handle.

However, this rocker is more refined in workmanship and is less likely to slip after being frosted. At the same time, there is a red button on the top, instead of being distributed on the control board like an arcade.

Of course, there is only one button.

Guan Fei only needs this button, and there is no need for other unnecessary buttons to issue combination skills. After all, this is a practical battle, and you cannot use big moves such as wave fists.

Then, he pulled out a copper signal line from the control board, and with the help of night and weeds, he quietly hung it to a nearby ten-meter-high tree to act as a remote control reception and sending antenna.

With this extension antenna, he can achieve remote control of the drone ten kilometers away without risking it to approach hundreds of meters before he can *************.

Even if he was very careful and slow, it took him more than ten minutes to complete it.

There is still plenty of time.

He personally determined the final flight route of the drone, and the procedures were entered by him, so he knew very well how long he would have to wait.

The flight speed of the drone is 200 kilometers per hour, and from the military sub-district to the airport is 216 kilometers. In order not to be discovered, the choice was to fly above the mountainous area. The total circumference is 294 kilometers, and the entire voyage takes one and a half hours.

He was not in a hurry at all, slowly relaxed his body, and ate a few pieces of chocolate to replenish his energy.

He will sacrifice his life to avoid the enemy's inevitable search if he completes the air strike later. He does not have enough physical strength to avoid it.

After eating the chocolate, he simply closed his eyes and took a nap.

At 7:49 pm, Guan Fei suddenly opened his eyes and woke up from deep sleep. He rubbed his face, cheered up, and took a deep breath to relieve his nervous mood.

This night attack is crucial, and he is not sure whether it can succeed. Therefore, even with the biological secondary brain, his heartbeat can't help but increase a little.

He finally sorted out his bags, took out the high-power telescope, and skillfully aimed at the airspace where the drone was about to appear, waiting for the rabbit to get up.

A few minutes later, a black dot appeared faintly at the dark place where the dark world met.

The enemy has air defense radar, so in order to avoid radar search, the drone will be reduced to a low altitude of 300 meters in the last thirty kilometers and perform ground flight.

For radars of this era, due to the curvature of the earth, it cannot be detected if it is higher than 300 meters.

At night, because there is a starlight in the sky, it will be a little light, and if there is no lighting on the ground, it will be much dimmer. Therefore, looking from the sky, you will find that it is pitch black and you can see almost nothing.

However, when looking at the sky from the ground, due to the different brightness of the upper and lower parts, the flying objects will be clearly visible. If they are too high, they may not be visible, but a moving flying object that is nearly ten meters long, at least at a low altitude of hundreds of meters can be discovered with the naked eye.

Therefore, in order to further conceal, the whole of this batch of drones was painted black to reduce reflection.

It is impossible to have no reflection at all, but this glimmer of light can no longer be distinguished by normal people with the naked eye. Only with the assistance of biological sub-brain can it be distinguished from the night sky.

Guan Fei was also on the top of the mountain more than 700 meters before he could see this small black dot in advance.

For the airport radar, this black point is still below the ground. When the radar waves hit the ground, it is absorbed and cannot be detected at all.

"The biological auxiliary brain runs at 8% of its power! Start the night low light pattern recognition program, remove the sky background, and strengthen the target contour on the ground. If strong light is detected, the light will automatically drop to a level that the naked eye can withstand!"

Guan Fei was silently reciting in his heart, and the dark scenery in front of him suddenly lit up, like a layer of gauze being moved away from his sight, and from night to dawn in an instant.

Although it was not yet clear that was as clear as noon, it was enough for him to see everything around the airport: the airport command tower, the runway, the hangar, the long row of various aircraft on the apron, the earthen cranes, weeds, the convoy patrolling with headlights, the walking guard team, and the air defense combat positions on both ends of the runway are all vivid in my mind.

When he let his pupils shrink and enlarge the scenery, he saw it as if he was right in front of him, and even the rice grains on the face of a patrol soldier could see clearly.

very good!

Guan Fei put the telescope back into his backpack, tied his pocket tightly, and finally let out a breath of depression. He held a rocker in his hands, focusing all his attention on the drone that was approaching quickly.

Under the precise control of the biological sub-brain, he pressed the red button at the top with his left thumb, sending a signal to the drone.

According to the program settings, the first time you press this key is to request to take over the aircraft and realize remote control flight.

And the second time is detonation!

The signal is transmitted from the antenna hanging on the tree behind him. It instantly reaches the drone at a speed of 300,000 kilometers per second, and is received through the antenna on the back, and then transmitted to the control circuit and handed over to the processor for identification.

Guan Fei's control panel also has a Chinese processor made by the military partition, and the encoded password telecommunications are also embedded. If this telecommunications does not resolve the processor circuit and the encoding method, it will definitely not be cracked, at least it will not be cracked in the short term!

Without sound, a green light diode on the control panel lights up, indicating that the drone has received the signal and switched to manual control mode by program control.

At this time, Guan Fei had handed over the control of his body to the biological subordinate brain, and there was no turmoil in his heart. He lightly controlled the drone to lower the altitude to fifty meters with his left hand.

Even experienced pilots may not be able to ensure safety at this height.

However, under the precise control of the biological sub-brain, the drone skillfully jumped up and sometimes dived at a height close to the ground, just like a seagull flying on the sea, approaching the airport quickly.

Until this time, no one at the airport knew that a terrible killer was approaching quickly.

Just as the first drone lowered its altitude under his control, the second drone also appeared in the predetermined airspace, with an error of less than twenty meters.

Guan Fei immediately issued a takeover order to the drone with his right hand rocker and successfully accepted control of it.

The signal identification codes of the two remote control joysticks are slightly different to show the distinction.

After the first drone received the previous signal, it ignored the second signal. Only when the same signal came again will the detonation code in the program be triggered. The same is true for the second drone, it does not pay attention to the interference of the first signal, automatically block it, and only execute the instructions of the second signal.

Although it is controlling two drones at the same time, it is no different for Guan Fei to control one.

One thousand meters...

Nine hundred meters...

...

Five hundred meters...

...

Three hundred meters...

Guan Fei's heart was Wubo, and his face was as calm as an old monk meditating. His pupils were either open or shrinking, firmly locking the flight trajectory of the two drones, accurately controlling each of their movements.

In a blink of an eye, the first drone approached the airport within 200 meters and entered the airport lighting range.

At this time, even at night, even if the whole body is painted black, it cannot escape everyone's eyes under the light.

A team of patrolling airport guards immediately felt an abnormality from the corner of their eyes.

They suddenly turned their heads, and before they could carefully observe what it was, they felt a huge black shadow swiftly passing by. After a second or two, the thing that seemed to be a large bird plunged into the four-unit anti-aircraft gun air defense combat position at the end of the runway.

Immediately afterwards, a dazzling light lit up from the fall.

The bright light spread rapidly and expanded outward in an instant, expanding to about twenty meters in diameter, enclosing the entire air defense combat position.

As the bright light expands, the light also dims rapidly, and it quickly transforms from a flash that cannot be seen directly into a bright red and bright red.

When the light ball expanded to about twenty meters, a shocking sound also spread along the air and the ground to the patrol team. The sound was so loud that it seemed like the earth was shaking, which made their hearts feel like they were about to explode, and it was so difficult to take a breath.

No, it's not as if it's actually shaking!

Everyone was shaken by the shaking ground and couldn't stand on the ground, and fell down staggeringly.

Just as they fell to the ground, they saw black on the edge of the red light, which was the smoke of gunpowder formed by the explosion. At the same time, countless things flew out of the fire and burst out in all directions.

Among them are the anti-aircraft gun barrels, shields, steering handles, and other objects that are large and small indistinguishable, and there seem to be a cluster of tiny round particles that fly out in it.

That's all the sights these soldiers could observe.

Hundreds of steel balls were like the strongest projectiles. In less than a second, they flew in front of them, penetrated the unblocked clothing, the surface skin, muscles, and even bones, and then penetrated them with splashing blood from behind them, making a sharp sound of breaking through the air and continuing forward, destroying all the obstacles that blocked their flight route!

For the airport guards further away, they saw a huge ball of flames soaring into the air. The bottom vacuum area formed absorbed the surrounding air and narrowed rapidly, turning into a mushroom-like cloud flying upwards.

When the mushroom clouds soared into the sky, there was no trace.

None of the soldiers stationed in this artillery position were still alive, and were swept up by the huge impact of the explosion, and were violently torn into pieces in the air. The blood instantly evaporated in the high temperature, and the broken limbs and arms were thrown hundreds of meters away.

Just when everyone was shocked by this scene, there was a jingle sound from another double-mounted anti-aircraft gun position two hundred meters away, accompanied by the heart-wrenching screams made by many people.
