In the southwest direction of the defense line, more than 200 alien spaceships flew in at great speed, and in the north of the defense line, there were also 500 alien spaceships, crossing the Hengjiang River and heading straight for the Jiushi Mountain defense area.

To ensure that the lightning storm has enough energy to fight.

Ling Feng ordered a group of robots to prepare 600 A5 energy crates for the thirty-five lightning storms in the north of the defense line, and 300 A5 energy crates for the twenty lightning storms outside the southwest defense line.

In this way, there are 900 A5 energy boxes deployed in these two defense lines alone, and there are only more than 300 energy boxes left.

Of the more than three hundred A5 energy boxes, Ling Feng temporarily placed them in the command center of the first line of defense, and then sent them over to replenish them when there was a need in the future.

Now that 900 energy boxes have been prepared for battle, it stands to reason that they should be able to deal with the more than 700 alien ships that are coming to attack.

Soon, it was about ten o'clock in the evening.

At this time, the robots monitoring the base frequently sent urgent reports, saying that the alien spacecraft fleet attacking from Jiangbei had now entered the territory of Gandong Province, and at this moment, it was less than 400 kilometers away from the Jiushi Mountain Defense Area.

Hearing this, Ling Feng's face sank, he took a deep breath, and ordered all the robots that controlled the lightning storm: "The robots on the northern defense line obey the order, as long as the enemy target is within the range of the lightning storm's kill, immediately fire and destroy them!" ”

"Yes, sir!" The robots on the north side of the defense line responded respectfully after hearing the order.

The alien fleet that attacked in Jiangbei was far from the first line of defense. When there were still 300 kilometers to go, suddenly, twelve defense bases monitoring the enemy's situation reported to Ling Feng again.

"Report to the chief, the alien fleet attacking from Jiangbei is still two hundred and eighty kilometers away from the defense area, but just a minute ago, more than 3,000 small flying machines suddenly appeared around the enemy fleet, forming a guard formation. Will be five hundred large ships. Firmly guarded in it! ……”

Hearing this, Ling Feng's heart was shocked, and he was secretly surprised: "It seems that those alien creatures who fled back last time. Definitely put things inside the line of defense. Told their companions. This time, they sent a large fleet to attack the defense area, and they should have prepared everything a long time ago, like those thousands of small flying machines that suddenly appeared. It is estimated that the alien spaceship was released to protect the fleet, and they did this, presumably to intercept their own fighters and prevent their spaceship fleet from being knocked down by crazy fighters again! ”

Thinking of this, Ling Feng's back was covered with cold sweat.

At the same time, he was secretly glad in his heart, fortunately, he had deployed a large number of lightning storms on the periphery of the defense line yesterday, and with the perverted attack power of the lightning storm, it was enough to destroy those flying machines.

Otherwise, if he still carried out a death attack on the alien invader's spacecraft in the same way as a few days ago, it is estimated that all the fighters he sent out would not end well.

Because the enemy's fleet is guarded by thousands of small aircraft, even if he sends more fighters to charge, it is estimated that they will be intercepted and destroyed by those small aircraft.

It seems that after the first two battles, they have probably figured out the offensive methods of those alien invaders, and those alien invaders, they have also spied on their own armed strength and counterattack tactics.

They must have calculated that the biggest threat to them is those crazy fighters.

As long as all the fighters that come to collide are destroyed, then their spaceships will enter the defense area unharmed and carry out large-scale destruction and destruction of the Jiushi Mountain defense base.

In this way, these alien creatures, their combat IQ is indeed not low, but unfortunately, they can't think of it, and they don't need to use fighter jets to attack them now.

Because, I have already prepared super killers to deal with them, and when the time comes, the more than 100 lightning storms deployed outside the defense line should bring a big surprise to those alien invaders.

Thinking of this, Ling Feng set his eyes in the direction of the alien fleet, the corners of his mouth turned up slightly, and he secretly sneered: "Come on, you disgusting guys, I will have a big gift for you later, hum!" ……”

At this time, it was already past ten o'clock in the evening.

In the dark night sky, there were five hundred behemoths, on top of the escort of thousands of small flying machines, flying all the way straight to the Jiushi Mountain Defense Area.

Tonight, all the alien spacecraft, flying at an altitude of less than two kilometers above the ground.

Thousands of small flying machines, like a nest of hornets, firmly protected 500 behemoths in all directions.

The alien fleet of such a large scale, in flight, constantly emitted bursts of dull roaring sounds, which frightened the wild wild birds in the wilderness mountains and forests on the ground, screaming again and again, and running in all directions.

This time, the alien spacecraft in the sky did not drop a large number of dark bombs on the ground, no matter what beasts or livestock appeared on the ground, they all turned a blind eye.

The goal of their attack was clear: a defensive line built by humans ahead.

The humans within this line of defense are too hateful and too difficult to deal with.

In the past few days, they have lost more than a hundred ships and nearly two thousand elite dark warriors in order to attack this defensive line.

This loss makes them angry, because they have conquered the entire earth in the past few days, although they have also suffered some losses in the process, but the total losses in the world are not more than half of the losses on this defense line in the past few days.

Therefore, today they will be scattered in Jiangbei all the spaceships with sufficient energy, all assembled, ready to completely bomb this defense line into ruins tonight, and those dirty humans hiding in the defense line will also be destroyed one by one.

Hundreds of huge ships quickly flew towards the defense line of Jiushi Mountain, and soon, they were less than 150 kilometers away from the attack target......

Ling Feng left the cockpit of the golden mecha and sat on the defensive wall and lit a cigarette.

Just after taking a few bites, the robot's alarm voice sounded in his head: "Report to the chief, the five hundred alien spaceships and more than three thousand small aircraft attacked from Jiangbei are currently less than one hundred and twenty kilometers away from the defense area, will you launch an attack?" ”

Ling Feng took a deep breath of his cigarette, threw the remaining half of the cigarette to the ground and stepped on it, and then ordered all the robots north of the defense line: "All the robots on the periphery of the northern defense line obey the order, the lightning storm will prepare for battle immediately, and in a minute, attack the enemy's fleet!" ”

"Yes, sir!" ……

At Ling Feng's order, all of a sudden, the thirty-five lightning storms deployed outside the northern defense line were all equipped.

At this time, five hundred alien spaceships, escorted by thousands of small aircraft, drove into the killing area of the lightning storm.

"Lock on to the target!" A ninth-generation robot in charge of Lightning Storm began to command.

Suddenly, the thirty-five lightning storm launch bases emitted a dull humming sound at the same time, and the thirty-five circular pagodas weighing hundreds of tons also began to tremble slightly.

At the top of the launch base, thirty-five giant cannon barrels, after a rapid rotation, Qi Qi aimed the huge cannon ports at the alien fleet a hundred kilometers away.

"Fire, attack!" The ninth-generation robot gave the order to attack suddenly.

Not! Not! Not! ……

Rumble!!!!!

Within the thirty-five giant cannon ports, a strong energy light wave flickered at the same time, and a moment later, all the cannon ports suddenly fired a series of extremely dazzling giant laser columns!

Suddenly, thirty-five incomparably thick laser pillars, like thirty-five giant lightning bolts that cut through the darkness, were like angry thunder, spanning a distance of nearly 100 kilometers, and the unparalleled destructive power of the carrier enveloped the area where the alien fleet appeared!

Rumble! Rumble! Rumble! ……

As soon as the giant laser pillar appeared, those alien invaders knew that something was wrong, and they panicked and controlled the spaceship, turning back and forth, preparing to escape from the laser pillar's attack range.

However, how can they react to the attack speed of lasers?

As soon as all the alien invaders discovered the appearance of the laser pillar, their fleet flying in the night sky suffered a fatal blow.

A series of extremely fierce laser pillars, it only took less than half a second to bombard through the small aircraft, and finally directly bombarded the hulls of those behemoths, in the blink of an eye, those extremely strong alien spaceships, under the bombardment of the laser pillars, quickly melted a huge hole, and then, the extremely powerful laser pillars slammed through the melting hole, directly from the outside inside, destroying the entire alien spacecraft.

Suddenly, the bomb bays of more than a dozen alien spaceships were hit by laser columns, and all of the dark bombs stored inside the spacecraft exploded.

Rumble! Rumble! Rumble!......

In an instant, the black flames in the sky rolled, and countless terrifying black shock waves spread out in mid-air like a mountain and a sea.

Suddenly, the air area with a radius of more than ten kilometers was all shrouded in the extremely violent black waves.

A large number of alien aircraft were swept by the black waves, and they were hit hard one after another, turning into clumps of coke and falling to the ground.

Like the larger alien ships, their defenses may be a little stronger, and although those black shockwaves will cause them less damage, they will be enough to cause them to lose control of their ships and then stagger and fall to the ground.

The nearly 100 spaceships and thousands of aircraft at the back of the alien fleet turned around and fled when they saw that something was wrong. (To be continued......)
