"Report to the chief, outside the fifth defense on the left side of the first line of defense, thirty-five alien aircraft have appeared, and at this moment, they are less than two kilometers away from the defense line!"

"Report to the chief, outside the No. 7 and No. 8 defense zones on the left side of the first line of defense, hundreds of alien aircraft have appeared at the same time, less than two kilometers away from the defense line......

In just a few minutes, Ling Feng received urgent reports from many robots in a row, seeing that those alien invaders were about to kill under his defense, it really made him anxious like ants on a hot pot, turning around non-stop. Pen ~ fun ~ pavilion www.biquge.info

Quickly manipulated the mecha to the defense line, and loudly ordered all the robots on the first line of defense: "All the machine guns on the left side of the first line of defense are fired, and the enemy must not be allowed to enter within a kilometer!" ……”

"Boom! ……”

Before Ling Feng's words were finished, suddenly, more than a dozen black dazzling light clusters the size of a football shot in from outside the defense line and landed on the defensive wall dozens of meters away.

Boom! Boom! Boom! ……

More than a dozen black light clusters suddenly exploded.

Suddenly, a black shock wave spread out, and in the blink of an eye, it submerged a radius of tens of meters.

All the buildings, cannons, and munitions that were submerged by the black shock wave turned into piles of pitch-black char at this moment, and the scene was truly thrilling.

Seeing this scene, Ling Feng was taken aback in his heart, and hurriedly looked up, and sure enough, hundreds of meters away from the black light cluster, more than a dozen alien flying machines appeared.

These alien vehicles have successfully broken into the blind spot of tank artillery. Within a kilometer of the first line of defense.

As long as they are less than a kilometer away from the defense line, then these alien invaders can use their dark rays to cause deadly damage to all munitions and construction facilities on the defense line.

Now, in such a short period of time, the defensive line was under the attack of more than a dozen flying machines, and the hundred-meter-long defensive wall was surrounded by their terrifying dark light. It's almost destroyed.

Like a large number of cannons and ammunition deployed above the defensive walls. and many of the main battle tanks beneath the defensive walls, all of which were reduced to charred rubbish under their attacks.

"Quick! Fast! Fast! Defensive areas No. 3, No. 4, and No. 5, hurry up and use all the anti-tank missiles and heavy machine guns. Be sure to bring these dozen ships to the enemy who break in. Kill them all......" Ling Feng stood within the defensive line. He roared loudly with a panicked expression.

Soon, under his command, several defensive areas on the first line of defense. At the same time, thousands of machine guns and rockets were dispatched, and they opened fire and bombarded the dozen or so alien invaders who had broken into the danger zone.

Da-da-da-da! Da-da-da-da! ……

Rumble! Rumble! Rumble! ……

Countless powerful cannon ammunition and countless anti-tank rockets poured out of the defense line like a storm and blasted straight at the aircraft hundreds of meters away.

Suddenly, the dozen or so alien aircraft that broke into the threat area were seriously damaged by such frequent and intensive attacks, and a large number of craters and dents appeared on the hull of their aircraft.

Originally, after these alien aircraft were attacked by tens of thousands of steel rain rockets, they suffered some damage, but the anti-armor submunitions of the steel rain rocket launchers did not cause fatal damage to them, but only left a large number of bullet marks on their aircraft.

However, now thousands of machine guns and anti-tank rocket launchers were bombarding them, and they were so close that they were suddenly bombarded with nothing to bear, and they were directly knocked to the ground.

Although they were blasted to the ground, Ling Feng's mood still couldn't be calm.

Just now, he saw with his own eyes that these dozen or so alien aircraft, under the siege of thousands of machine guns and rocket artillery, they can still keep firing and counterattacking.

At the tip of each alien spacecraft, there are three launch pipes the size of bowls, and every few seconds, three black light clusters the size of soccer balls are emitted from within their launch pipes.

Anyway, in the process of competing with these dozen alien vehicles just now, the thousands of cannons and anti-tanks that attacked them were almost destroyed by their black light clusters.

To be able to successfully knock them to the ground, the robot door on the first defense line can be said to have spent a lot of effort and cost.

Due to the alien vehicles that just broke in, they caused great damage to the fortifications and weapons and equipment on the defense line.

Now Ling Feng had to quickly leave the first line of defense and hide in the second line of defense to command the battle.

50,000 main battle tanks are still firing and bombing, but more and more alien aircraft are pouring into the dangerous area like a tide, and they are frantically attacking tens of thousands of tanks deployed under the defense line.

Although the artillery and heavy machine guns and other armed firepower on tens of thousands of main battle tanks have been constantly strafing and bombing the enemy, they still pose a limited threat to those alien invaders flying in the air.

Especially when more than 100 alien aircraft, scarred, broke through the artillery blockade and narrowed the distance and defense line to within a kilometer.

Suddenly, these tank groups deployed under the defense line suffered fatal damage.

Tens of thousands of main battle tanks, their machine gun bullets and rockets, in the dark of the night, like a line of fire, spread all over the wilderness.

But helplessly, the defense of those alien vehicles is too perverted, although their sturdy hull has been bombarded by countless bullets and shells, but as long as they are not destroyed, their counterattack is for those tank groups. It's a nightmare.

Hundreds of alien vehicles often launch hundreds of dark light clusters at the same time, and all of them can hit the target in an instant.

A dark light cluster exploded, casually and suspiciously destroying several main battle tanks, hundreds of light clusters exploded together, and in an instant, Ling Feng had to lose at least a thousand main battle tanks.

At the same time, the dark light they emitted also caused extensive damage to the thick defensive wall.

In just a few minutes, the 50,000 main battle tanks that Ling Feng deployed outside the defensive line were damaged by thousands.

It took such a heavy price to destroy hundreds of flying machines of the alien invaders.

Finally, tens of thousands of tanks deployed outside the defensive line fired all the shells.

At this time, there was no threat of long-range artillery fire, and the alien vehicles that were blocked in the threat area all rushed into the danger area with great momentum, no matter how dense the machine guns and machine guns above and below the defense line were, they still could not stop their progress.

At this time, a large number of robots kept reporting to Ling Feng: "Report sir, there are already one thousand and forty-three alien flying machines that have broken into our defense zone!" At present, the firepower of our defensive line is limited, and it is simply impossible to inflict fatal damage on the incoming enemy in a period of time! Request support! ……”

Ling Feng stood within the second line of defense, and his heart was really nervous to the extreme.

He never imagined that these alien invaders were so ferocious, not only could 48,000 steel rain rockets be helpless against them, but even the dozens of shells fired by 50,000 main battle tanks could not completely annihilate them.

Although nearly 1,000 of the nearly 2,000 alien aircraft were killed by their own armed firepower, there were still thousands of aircraft that entered the dangerous area, posing a huge threat to their own defense lines and weapons and equipment.

No, find a way to solve them as soon as possible, otherwise, after a long time, a large amount of equipment deployed on the first line of defense will be greatly damaged by them.

However, for a while, he had no weapons and equipment to deal with them effectively.

Although there are still a large number of fighters and bombers stationed in several airfields, those fighters simply cannot fight under a hundred low altitudes, and those flying machines are not able to defeat those alien aircraft with perverted defense.

What to do? Now what? It seems that he was too careless just now, underestimating the combat effectiveness of these alien invaders.

Thinking of this, Ling Feng rubbed his forehead painfully, suddenly, as if he remembered something, he came to his senses in an instant, and at that moment he patted his head violently, and secretly scolded: "I'm really in a hurry, I actually forgot that I still have nearly 10,000 gunships!" ……”

Immediately, he quickly contacted all the robots driving the helicopter gunships, and ordered them to send 3,000 Apache gunships to fight in the fastest time to support the first line of defense!

"The Apache helicopter gunship team obeys the order, and you will immediately dispatch 3,000 Apache to counterattack the enemy who invades the first line of defense!"

"Yes, sir!"

Under Ling Feng's order, soon, the robots stationed in the first and second lines of defense quickly dispatched 3,000 fully armed Apache helicopter gunships to the first line of defense for fire support.

Click! ……

Thousands of Apache helicopter gunships were dispatched in unison, and suddenly, the overwhelming propellers spun wildly, creating bursts of deafening noise.

At the same time, the strong winds from the helicopter blew the vegetation and trees inside and outside the defense line, swaying from side to side, almost tearing.

When a pair of helicopter gunships swept over the field, all of a sudden, the dead branches and leaves, dust and gravel on the ground were blown into the sky, and the scene was as amazing as a sandstorm within the defensive line.

At this time, the offensive and defensive battle on the first line of defense has entered a white-hot stage. (To be continued.) )
