- The whole fortress is boiling, and all the military fighters are mobilized, and they have taken their places, and they have transferred their monstrous anger to the pirates of the alien civilization in front of them, and they are holding back their strength to gather each other here and let out a good breath of evil.

The Grimm fleet stationed in the fortress still has a complete division, nearly a thousand warships, and now, all the battleships that can fight have risen into the air and are waiting in the airspace around the fortress.

Although the incoming enemy warship group was huge, with more than 3,000 ships, they were still confident, relying on the ground positions in the rear, to fight each other and teach the enemy a hard lesson.

They have this confidence, the other party is defeated in a hundred battles, it is their subordinates who are defeated, and this time will be no exception, I believe that this time, it is the last time these alien remnant pirates jump, and this is the place of their complete annihilation!

The idea of the Grimm people in the fortress is good, but what they never expected is that the alien alliance on the opposite side has already hooked up with the Milky Way people and formed an alliance, and this time the large army that came here included a small fleet of the Milky Way, ten main warships, and a thousand armed flying saucers.

Such a small fleet may seem small, but it is enough to kill the Grimns.

According to the prior agreement, the support fleet of the Milky Way is responsible for clearing the Grimm fleet above the fortress. When the Milky Way warships lined up, the dock mouth opened, and one armed flying saucer after another flew out, forming a formation in front of the battlefield, the fate of this fortress guard fleet of the Grimm people was already sealed.

"Boom, boom—"

This is the Grimm ground positions opened fire and launched interstellar missiles. One after another, the fire dragons streaked through the sky, and in a short period of time, they broke through the shackles of the planet's gravity and entered outer space, roaring towards the approaching alien alliance fleet at full speed.

Interstellar missiles that have entered outer space, without the constraints of the planet's gravity, have become "dust" wandering in this star field, and theoretically can strike at a long distance as long as they are under the guidance of radar and as long as they are within the radiation range of radar waves.

So the strike range of the interstellar missile can undoubtedly reach a long distance. Theoretically, it can reach the range of the star field. It is like a "tiny satellite" that can roam the entire satellite domain covered by ground-based radar waves, provided that as long as it is not captured by the gravitational pull of other stars in the field, the more powerful the ground-based radar station is. The wider the airspace covered by radar waves. The greater the strike range of the interstellar missile.

Of course. In reality, it is impossible for an interstellar missile to hit a target at any long distance like this, because the strike distance is too long. The interstellar missile travels in the void for a long time, which increases the risk of being intercepted by the opponent's anti-missile missile.

Therefore, the interstellar missile will only be launched after the target is close enough to a short distance, which is also more threatening.

The topography of the Prague Fortress is undoubtedly very conducive to defense, with more than 20 small satellites crisscrossing the main base in the middle, forming a three-dimensional defense network.

Such terrain is not conducive to attacking from all sides, so the attack tactics adopted by the Interracial Alliance are also very simple and clear, that is, to concentrate all forces, concentrate on choosing one direction, and carry out a strong attack and breakthrough.

All the ground artillery positions of the fortress, including the main base and the artillery positions of the twenty or so satellite bases in the surrounding airspace, opened fire at the same time, and for a while, I saw ten thousand cannons firing in unison, and countless fire dragons streaked across the sky, shining the entire starry sky as if it were day.

Because of the difference in distance and distance, these interstellar missiles do not arrive at the target at the same time, and there will be a time difference, but if the launch frequency and interval are controlled, the maximum intensity of the attack wave will also be formed in the follow-up attack, which is equivalent to a salvo.

After the ground positions of the Grimmites opened fire, the alien alliance fleet also aimed at the target one after another, launched anti-missile missiles, and intercepted the incoming interstellar missiles, the firepower of the interstellar missiles was very fierce, and the lethality of the battleships was very large, and for some small warships, it was completely possible to achieve the result of instant killing.

At the same time, from the artillery launch port of their warship, a series of fire dragons were also spewed out, which were air-to-surface interstellar missiles specially aimed at ground positions, and the characteristics of this kind of missiles were that they had a large strike coverage, and they could hit targets within a radius of thousands of miles with a single flick, which was really a big killer for attacking ground positions, and once the ground artillery positions were hit, it was basically a dumb fire.

The two sides began a fierce battle against each other.

At this time, the fleet above the Grimm fortress, under the cover of ground artillery fire, launched a charge against the incoming enemy.

But their menacing charge was soon interrupted, and when their warship rushed to a million kilometers away from the opposing alien alliance fleet, a beam of deadly light shot from the opposite sky, and the Milky Way people had been waiting for the armed flying saucer group to open fire.

"Whoosh-whoosh-whoosh-"

One after another, the beams of positive energy heat, like deadly ghosts, hit the battleships of the Grimnes who charged one by one, and the mighty and sturdy warships of the Grimnes, after hitting the beam head-on, seemed to be fragile soap bubbles, which burst in an instant, and there were big explosions in the airspace one after another, and thick mushroom clouds rose up, and the entire airspace was shrouded in thick smoke screens, which was extremely tragic.

The Grimmites were stunned. Only this round of salvo, nearly a thousand Grimm warships were beaten to pieces in the blink of an eye, and the losses were exhausted, and the fleet like a dark cloud quickly disappeared and shrank in the blink of an eye, leaving only less than a hundred lone ships.

The Grimmites were stunned by this head-on blow, and before they could come to their senses, another round of deadly salvos was killed, and the remaining remnants of less than a hundred warships were also destroyed and exploded one by one, and a thick mushroom cloud appeared.

The entire fleet of thousands of ships was wiped out in the blink of an eye, and there was no scum left.

Seeing the instant destruction of the Grimm fortress fleet, the alien alliance side rejoiced and boosted morale, while the Grimm side was stunned and almost couldn't believe this fact, but the facts were in front of them, so they couldn't believe it.

Their fortress fleet was indeed slaughtered and annihilated like this by the other party!

The fortress was suddenly filled with a lot of mourning, and morale completely fell to the bottom.

"It must be the Milky Way!"

The commander of the Grimm Fortress, Biksic stood in front of the large screen in the command hall, stunned as if petrified, and after a long time, he had to accept the fact that his fleet had been completely wiped out by the other party, and then he realized that it must be the Milky Way people coming.

With those alien alliance pirates alone, it was impossible to wipe out their nearly a thousand warships in the blink of an eye.

Biksic clenched his fists, his expression was depressed and defeated, his heart was both distressed by the instant destruction of his fleet, and terrified by the imminent tragic end, the loss of the fleet guarding the fortress, the fortress completely lost air supremacy, and there was basically no suspense in this battle, and the fall of the fortress was inevitable.

After completely annihilating the fleet of the Grimmites in Prague Fortress, the support fleet of the Milky Way people has completed its mission, and thousands of armed flying saucers began to fly into the battleship one after another, preparing to withdraw from the battlefield in order to avoid the possible crazy retaliation of the Grimmites in the future.

The confrontation between the alien alliance fleet and the ground positions of the fortress continued, but fortunately, until now, the human support fleet was safe and sound, and did not suffer any losses.

Naturally, the artillery fire of the ground positions of the Grimmites would not be aimed at the flying saucers of the Milky Way, and the targets they prioritized were naturally those warships of the Alien Alliance fleet. Of course, if they knew in advance that this was the flying saucer of the Milky Way, they would be the heinous murderers who slaughtered their fleet, and they would definitely not let it go, and they would definitely give priority to attacking.

And the ten warships of the human race, in this round of strikes, two battleships also suffered a few shots, but fortunately, there was a new type of energy shield to block it, but there was no danger.

As for the warships of the Alien Alliance, in this round of artillery salvo fire from the ground positions of the Grimm, more than ten warships that were unfortunately targeted by the other side were destroyed, and the ground positions of the Grimmites were inevitably bombarded by the fleets of the Alien Alliance, and many positions were hit by artillery fire and were dumbfounded.

According to the prior agreement, the human support fleet was only responsible for killing the Grimm fleet, and did not participate in the ground attack on the fortress, so after the thousands of armed flying saucers returned to the battleship, the ten human warships greeted the headquarters of the Alien Alliance, and quickly began to turn around and leave the battlefield.

The headquarters of the Interracial Alliance did not say anything, the Galactic people had already annihilated the fleet of the Grimm Fortress, and they had done them a great favor, how much more could they ask for, and now they only have gratitude in their hearts, and there is nothing to complain about.

And they also believe that without the threat of the fortress fleet, they can calmly arrange, steady and steady, it can be said that the Prague fortress in front of them is already in the bag, and the fortress without air protection cannot compete with their fleet with the artillery fire of the ground position alone.

The Milky Way warships left the battlefield, first of all, they were worried about the retaliation of the Grimm, although there was a new type of energy shield protection, but this was not the kind of small base of the Jialan Star Base, if the Grimmites were determined to avenge their fleet, leaving the Milky Way Warships, under the fire of ten thousand guns, I was afraid that their ten warships would only fall here.

Second, this is also a predetermined plan before the war, in fact, it is useless for them to stay here now, and it is impossible for their positive energy thermobeam artillery to attack the ground position, and their missiles will not pose any threat to the opponent's position, so it is better to evacuate as soon as possible.

What happened next had nothing to do with them, and they also believed that there was no suspense in this fortress raid. (To be continued......)
