In the second line of defense, a large number of warships were activated in each defense area, and they drove out of the defense line one after another and flew towards the first line of defense.

This was originally one of belter's backers for the war.

Now, it has been used early.

"General west, all Gravity Gun warships have reached the designated position!"

Dozens of seconds later, the adjutant turned to report to WESTBANK!

"OK, order them to open fire immediately, assist the garrison on the first line of defense, and press the Zerg attack back!"

"I understand!"

Five billion Gravity Gun warships are scattered in 58 defense areas, with an average of more than 80 million warships deployed in each defense area.

At the moment of getting the order, they all gave out their own roar!

It has also been said before that unlike ordinary weapons, gravity guns are actually the further use of space technology. Therefore, they do not need a firing path. Once they fire, they will directly act on the attack point.

In other words, the gravity gun can carry out the general attack of fighting cattle across the mountain. It only needs to hide behind the defense line and keep firing. Most of the attacks of the Zerg will be blocked by the fleet on the defense line, and the threat to the Gravity Gun fleet is very small.

After firing, there is almost no time interval. In the front of the Zerg fleet, gravity tides appear in countless small areas in an instant. Then the uneven distribution of gravity leads to the tearing phenomenon. Finally, in a few seconds, all the Zerg warships in the area are destroyed!

Although the gravity gun is only the original version of space tearing, its attack range is not small!

The killing range of each gravity gun is about 30 kilometers!

In terms of the array density of the Zerg fleet, such a range is enough to cover about ten warships!

Finally, after the gravity gun attack, it directly acts on the target position. There is no time interval between them. That is to say, aiming means destroying. You have no chance to evade!

Therefore, the 5 billion gravity warships, just a wave of attack, caused huge casualties of the Zerg fleet, and destroyed tens of billions of them!

After all, the front of the Zerg fleet is close to the defenders on the first line of defense. Therefore, the overall array is not in the state of high-speed advance, and the warships are crowded together in a high-density state.

Only in this way can this wave of attacks achieve such great results.

If, like gilt's encirclement and annihilation war, he always deliberately kept a distance from the other side and scattered the fleet array, the casualties would be countless times smaller!

However, this is not the Zerg style!

The attack of the whole Zerg fleet stopped for a moment, while the garrison on the first line of defense took the opportunity to reorganize the firepower network and stiffly resisted the Zerg fleet that was about to face.

"Gravity Gun?"

It's also a bit of a surprise to watch Helmy on the battlefield through the Zerg spiritual network!

He thought that the highest level of civilization in this galaxy was only in the middle stage, but the scene before him changed his mind!

Gravity cannons can't be made by a medium-term civilization of level five. They involve some advanced applications of space science and technology. It's usually possible to master only the late or even peak civilization of level five!

Yes, it's just possible to master it. Most of the civilizations that master this kind of science and technology are level 6 early civilizations!

Although it seems that the range and speed of the gravity gun in front of us are a little less than what we know, the main weapon of the early civilization warship of level 6 is gravity gun, but we can't deny that it is gravity gun. It's just a little primitive.

Fortunately, the number is not many, only a few billion, if there is a trillion, Hermes should consider withdrawing, or even escaping from the Galaxy!

In fact, what Helme didn't know was that the Gravity Gun accidentally developed by Wilto's scientific research team was much worse than the level 6 early civilization in terms of power and attack interval, and its attack distance was even closer!

It is necessary to know that the main weapon used in level 6 civilization, namely gravity gun, is at least 20-30 million km in attack distance, even if it is only in the early stage.

By comparison, Vera's gravity gun is more than a generation behind!

Although the Gravity Gun fleet has shown its powerful attack power, it seems that it can only suppress the progress of the Zerg, which is already the limit. It seems impossible to beat back the Zerg fleet.

The most important thing is that although the gravity gun is powerful, it consumes a huge amount of energy every time it fires. When the energy reserve is sufficient in the early stage, it can attack at the speed of once a minute.

However, after a period of time, the reserve energy is exhausted and can only be recharged by the core energy. Limited by the output speed of the core energy, after ensuring the normal operation of the warship and maintaining the space shield, the firing speed will be reduced to about once every three minutes.Sure enough, five minutes later, the attack frequency of the Gravity Gun fleet suddenly dropped, forcing the Zerg fleet to a situation of one million kilometers away. Now, due to the lack of follow-up firepower, the Zerg is again under pressure!

"Damn, even if the Gravity Gun fleet is used, it still can't suppress the Zerg to a safe distance!"

Looking at the pictures and various materials displayed in the tactical video, West said out loud.

"To bring back the Gravity Gun fleet, general?"

"No, let them continue to attack, cooperate with the defenders on the first line of defense, and try to delay the time for the Zerg to come up!"

"But...

" no, but, now! "

"Yes, general west!"

In fact, for the adjutant, West's order puzzled him.

Now the Gravity Gun fleet has lost its biggest role. The best strategy is to withdraw the second line of defense, recharge the reserve energy, and then cooperate with the second line of defense.

However, looking at the meaning of general west, it doesn't mean to let them withdraw at all. On the contrary, it seems to be preparing to let them survive together with the first line of defense!

This made him very puzzled!

"Even if the attack power drops suddenly, but with the cooperation of gravity gun and the first line of defense, it's still no problem to continue to resist the Zerg for 10-15 minutes, and this time is enough for us!"

"Because... The strongest reinforcements will arrive soon!"

Looking at the adjutant's face full of doubts while ordering, West said as if to himself.

The strongest reinforcements?

What is the general talking about?

Even the fleet of the big three has run away. Where is the reinforcements, and they are still the strongest?

Wait, isn't it?

"General west, a large number of fleets are arriving one after another in all the battlefields!"

"This is... This is the battleship of the human Federation!"

Just as the adjutant guessed, the voice of the Suo enemy officer came to his ear!
