Sixteen behemoths, staggered by hundreds of fighter jets, and after a violent tremor and shaking, they fell uncontrollably.

The place where it fell was Qiulin County, which was dozens of miles away from the first line of defense.

Boom! Boom! Boom! ……

A series of earth-shattering loud noises sounded one after another in Qiulin County.

As the sixteen behemoths smashed ferociously to the ground, Ling Feng, who was standing within the first line of defense, clearly felt that the earth was trembling slightly.

At that moment, he waved his fist excitedly and said excitedly: "Okay! Damn, I've finally taken you off the ground, now it's time for you to taste my awesomeness! ”

Driving the golden mecha violently, he flew to the top of a defense tower, glanced coldly in the direction of Qiulin County, and ordered loudly: "All the robots in the first line of defense obey the order, and immediately prepare two hundred Guard-2 large rocket launchers to bombard the targets that fall in Qiulin County!" ”

"Yes, sir!" After receiving the order, the robots in the first line of defense responded loudly.

A moment later, under the rapid preparation of a group of robots, two hundred Guardian-2 rocket launchers quickly locked on and aimed at the attack targets in Qiulin County, preparing to blow up all the sixteen alien spaceships that crashed in Qiulin County with a thunderous force.

Just when the two hundred Guardian 2 guns in the first line of defense were preparing, the sixteen alien ships that fell to the ground suddenly. There has been a change.

I saw sixteen behemoths, pitch-black and sturdy giant hulls, suddenly roaring and trembling, and then, on the tops of all the alien spaceships, several hatches with a radius of several meters opened.

Almost at the same time, a giant triangular cannon barrel suddenly protruded from within these black hatches.

Those triangular barrels are at least one meter in diameter and up to two meters long. Don't know about these barrels. What kind of terrible alien weapon is it used to launch it?

Soon, the monitoring base on the periphery of the defense line urgently reported the matter to Ling Feng.

When Ling Feng heard this, he was taken aback. Hurry to the robots who are operating the Guardian 2 rocket launcher. Urging loudly: "Are you ready to aim?" When you're ready, shoot now! ……”

At his urging. There are dozens of Guardian 2 rocket launchers that have already been aimed, and all of them are starting to attack!

Shout! Shout! Shout! ……

Dozens of giant rockets weighing more than 1,000 kilograms were like fierce meteors. Dragging a long flame tail, it shot towards the territory of Qiulin County like lightning!

Just as the first round of rockets was launched, more than 100 other Guard-2s were all aimed.

For a time, two hundred Guard-2 long-range multiple rocket launchers fired hundreds of giant rockets at the Qiulin County area, looking like this, almost trying to raze the entire Qiulin County to the ground.

Soon, Ling Feng clearly saw that in the territory of Qiulin County, there were constantly sky-high fires, and then, bursts of explosions like muffled thunder continued to spread to the first line of defense.

Obviously, the giant rockets launched by the two hundred gate guards 2 should be extremely terrifying, and the disturbances in Qiulin County are also extremely huge, but I don't know, those sixteen alien spaceships, under the bombardment of hundreds of giant rockets, have there been fatal damage?

Because, so far, in Ling Feng's mind, there has been no reward prompt sound from the system.

Two hundred Guardian-2 long-range rocket launchers and 1,200 launch pipes fired giant high-explosive rockets one after another.

In just one minute, 600 huge rockets had already rained down on the territory of Qiulin County like a storm.

Under such a fierce bombardment, Qiulin County, dozens of miles away, was completely reduced to a sea of explosion!

Suddenly, in the direction of Qiulin County, hundreds of black pillars of light about one meter thick burst out, and they swept towards the first line of defense!

Rumble! Rumble! Rumble! ……

In just dozens of kilometers, hundreds of black pillars of light are here in the blink of an eye!

What's even more frightening is that these thick black pillars of light, like black swords, pierced through one building after another, broke one big tree after another, and finally bombarded the first line of defense.

Suddenly, the defensive wall with a thickness of more than ten meters was directly bombarded with hundreds of triangular holes, and after the black pillar of light blasted through the solid reinforced concrete defensive wall, it actually hit more than a dozen tanks and artillery deployed behind the defensive wall without diminishing its power before gradually weakening and disappearing.

Ling Feng stood next to a triangular hole with a shocked face, almost suffocating in shock.

Just now, he saw with his own eyes that a pillar of black light pierced through the solid defensive wall around him, blasted through one main battle tank after another, and finally disappeared.

In such a short instant, he lost thousands of main battle tanks and artillery, and the solid defensive line he spent countless manpower and material resources to build was equivalent to nothingness in front of these terrifying dark pillars of light!

It's horrible! The attack of these alien creatures is really terrifying!

Ling Feng was short of breath, his chest was constantly rising and falling, and until now, he had not recovered from the shock just now.

At this time, a large number of robots kept reporting to him that the two hundred attacking Guardian-2 rocket launchers they had just deployed had been destroyed by those dark pillars of light.

Hearing this, Ling Feng hurriedly ordered loudly: "Add me another hundred rocket launchers, bombard the target with all your might, and you must completely destroy them!" ……”

As soon as these words came out, hundreds of eighth-generation robots, controlling a hundred Guardian 2 rocket launchers, joined the bombardment camp against those flying ships.

Hundreds of giant rockets, frantically roaring out from the launch pipes, rained towards the place where the dark pillar of light had just appeared.

With one rocket after another, flying and whistling in the sky, the sky-high firelight, and the earth-shattering explosion sound came from the territory of Qiulin County in an endless stream.

At this time, for the sake of safety, Ling Feng had to drive the golden mecha and retreat to the second line of defense.

Because, it is too dangerous to stay within the first line of defense.

He was almost hit by those terrifying pillars of dark light just now!

Although the defense of the golden mecha is very strong, no matter how strong it is, he does not dare to guarantee that his golden mecha can withstand the attacks of those dark pillars of light.

After retreating for dozens of miles, Ling Feng's heart was steady.

At that moment, he began to command hundreds of Guardian 2 rocket launchers, and carried out carpet bombardment of the places where the alien spacecraft fell.

In just a few minutes, more than 200 Guardian 2 rocket launchers fired nearly 3,000 giant high-explosive rockets, such a huge firepower could almost completely bomb the entire Qiulin County into ruins.

Under such a high-density and high-frequency bombardment, it is impossible for those alien spacecraft to withstand it.

Sure enough, when the two hundred rocket launchers launched the thirteenth round of attacks, finally, Ling Feng's mind remembered the system's reward prompt.

"Congratulations to the chief for successfully destroying a Precursor, so the system will give you a reward for mecha redemption permissions, may I ask, do you want to accept the reward immediately?"

Hearing this, Ling Feng was extremely excited, and hurriedly responded: "Yes, I want to accept the reward immediately!" ……”

After accepting the reward of this mecha exchange permission, Ling Feng did not relax his vigilance, but kept ordering the robot: "Keep banging me!" Be sure to destroy all targets! ”

Rumble! Rumble! Rumble! ……

Hundreds of giant rockets continued to fall in Qiulin County.

During this period, Ling Feng's mind sounded more than a dozen reward prompts from the system.

Finally, when the system prompted, Ling Feng learned that all the sixteen alien spaceships that crashed in Qiulin County were successfully destroyed by thousands of rockets, he breathed a deep sigh of relief, and then ordered all the Guardian-2 rocket launchers to stop the attack!

At this moment, the robot in the monitoring base suddenly reported to him: "Report sir, in the area of Qiulin County, hundreds of small flying machines suddenly appeared, and they are now secretly rushing towards Jiangbei at a supersonic speed......

Hearing this, Ling Feng's face changed, and he was secretly surprised: "I said that I just destroyed more than a dozen alien spaceships, and I only got the reward for destroying the alien spaceship, like destroying aliens, there should also be a reward, but the system didn't prompt any of them, it turned out that those cunning alien creatures actually all escaped!" ”

Thinking of this, Ling Feng was going to order the missile base to launch missiles to pursue those alien creatures that had escaped, but after thinking about it carefully, he still forgot it.

Consuming missiles to chase down the escaped aliens is not a good deal at all.

You know, the power of anti-aircraft missiles is really limited, even if they hit those alien vehicles that escaped, it is unknown whether they can successfully destroy them.

Now all the anti-aircraft missiles in the missile bases are not very rich in the first place.

In the future, if a large number of alien ships attack his military defense area, then he can still keep these anti-aircraft missiles and use them to consume the dark rays of those alien ships.

Otherwise, if you don't drain their defenses, how can your own fighters hit them to the ground?

Thinking of this, Ling Feng shook his head and sighed secretly: "It seems that those alien invaders are far more difficult to deal with than he imagined!" Sixteen alien spaceships came tonight, and they kept themselves busy, and if a hundred or a thousand alien ships attacked their defense area in the future, what would they do? ......"
