"Report, the energy reaction at the channel mouth continues to fluctuate."

"Report, the attached civilization fleet has been dispatched, and it is expected to start jumping and entering the defense line in 7 seconds."

"Report, there's an unknown glitch in quantum communication!"

......

Unknown failure of quantum communication?

It should be right, here they are!

"Activate the space map communication, immediately contact the military department, and report the situation here!"

"Yes, Captain!"

Before the fleet came out, communication jamming began first.

I have to say that this hand is indeed very effective against civilizations below the fifth order, or those who have just been promoted to the fifth order.

But for today's federal...

but no longer have.

Over the years, space communication technology has been thoroughly matured, and although it has not yet spread to every warship, a large number of warships equipped with space communications are now deployed in every fleet.

These warships can be used as transit stations, and after receiving orders from the base camp's own space communications, they can then use short-range laser communication to disperse and transmit the information to each warship.

"Legion Commander, there you have appeared!"

"Give me an observation!"

"Yes, Captain!"

In the next second, an image appeared on the bridge.

In the picture, at least 2,000 warships slowly flew out of the huge passageway.

"Sure enough, it's this group of guys, is the attached civilization fleet in place?"

"It's all in place!"

"The attack begins, tell them not to be afraid of energy consumption!"

"Yes, Captain!"

At the same time, hundreds of light-seconds away, only ten light-seconds away from the channel mouth.

Millions of Combined I warships suddenly erupted in a roar.

Countless attacks enveloped the past in an instant.

The Joint I battleship did have some crotch pulls.

However, its crotch pull is manifested in the fact that it is not equipped with a space shield.

On every Combined I battleship, there is a space penetrating cannon, albeit a castrated version.

But it's only the firing range that is castrated, as well as the recharge efficiency, and so on.

In terms of power, there is actually no such thing as castration.

After all, this is not a weapon of the old times, and it can be charged more, less, or the power of the ship's guns can be reduced.

This is a spatial attack, and there is nothing to block its attack except for a spatial shield.

Although, in the third-class legion of the Silver Light Empire, those warships also have space shields.

But the number of combined warships on the defense line is huge.

Millions of ships set fire to 2,000 ships.

Even if it's a battle star of the Federation, it can't be carried by it.

One battleship after another was blown up by volleys, and even those that were not blown up were pierced through countless holes in the hull.

The internal air leaked wildly, and in serious cases, it was even directly paralyzed.

"Commander, the first wave of salvo attacks will destroy 1,576 enemy ships!"

"Keep attacking and wipe them all out."

"Yes, Captain!"

At this moment, the million combined warships on the defensive line have begun to recharge and are ready for a second round of strikes.

But not before they were ready.

The other party took the lead.

Standing in the bridge, Luo Yu could clearly see that in the battlefield observation image, the space where a joint warship was located suddenly distorted, giving people the illusion of a visual model.

A few seconds later, when the distortion disappeared and everyone looked over again, they took a breath.

At this moment, the picture is no longer a joint warship, but a mess of twisted flowers.

Sure enough, as long as it is a spatial attack, each one is very terrifying.

Fortunately, a wave of concentrated fire just now killed most of the opponent, so this wave of counterattacks is not a big threat to the fleet on the defensive line.

Only a little more than two hundred warships were destroyed.

However, it's not that simple.

"Commander, the second fleet of the enemy has emerged from the unknown passage, the number is 2000."

"Activate the starry sky defense chain, and at the same time order the first cluster of affiliated civilizations to continue to output!"

"Yes, Captain!"

------

A few minutes later.

Virtual meeting room of the military department.

Commander-in-Chief Mu Zhengfeng and Chief of General Staff Gao Tianyang were already sitting in it at the moment, as if they were waiting for someone.

In the next second, Jiang Xingchen's figure was projected.

"Commander!"

"Xingchen, do you know the situation on Sextant A?"

"Yes, but the details are not clear."

Nodding, Jiang Xingchen said.

Indeed, he knew that the fleet of that unknown civilization had once again arrived at Sextant A, and that the battle with the defenders had already begun.

But the details of the battle, he really didn't know.

After all, at present, Mu Zhengfeng has just finished reading the report that Luo Yu has worn.

"Very good, you can learn more about the details on the road, what you have to do now is to make the development fleet ready and set off in the shortest possible time."

"Yes, Commander!"

Nodding, Jiang Xingchen directly exited the virtual conference room.

After all, this is not a regular military meeting, and Mu Zhengfeng's order has been issued, and he must complete it in the shortest possible time.

"Ling Xiao, the first to second legions, directly subordinate legions, and elven legions are urgently assembled, and the combat readiness level of the development fleet is adjusted to 1."

"Yes, Commander!"

Nodding, Ling Xiao immediately went to do it.

And Jiang Xingchen touched the armrest of his command chair a few times.

A few seconds later, a figure was projected in front of it.

"Lao Luo, the military department has ordered us to immediately = go to Sextant A to take over and take charge of the defense line over there."

"In an hour, I will lead the First and Second Legions, the legions directly under the headquarters, and the Elven Legion in combat preparation."

"As for the 3rd to 6th legions in the rotation, after recalling all the soldiers, they will set off as the second echelon, led by you."

Looking at Luo Fei, the chief of staff of the Pioneer Fleet in front of him, Jiang Xingchen said.

"Don't worry about going first, I'll take care of the rest!"

"Well, thank you!"

------

Sextant a.

Unknown channel port.

At this moment, at the speed of each wave of 2,000 warships, this third-class legion under the command of the Silver Light Empire had already flown out of the passage with almost 50 waves of warships.

50 waves...

That is, 100,000 warships.

Almost 10% of the defenders on the defensive line.

Of course, you can't do that way.

After all, in the defensive battle at the mouth of the passage, the defenders have an absolute advantage.

Due to the width of the passage, the attacking side cannot allow all ships to enter and arrive at the same time.

Take this third-class legion as an example, each wave reaches 2,000 ships, which is already the limit.

At the same time, the defender can also set up a hemispherical defense line centered on the passage entrance, attacking from all directions to form a super firepower network.

In the era of cold weapons on the home planet, if you want to attack a city, you usually need several times the strength of the defenders.

But put it on this kind of channel mouth offensive and defensive battle in the interstellar age...

I'm afraid that it will only be possible if you have to have dozens of times the number of troops.

After all, in the early stages, the attackers were at an extreme disadvantage in terms of numbers and position.

It will take a long time to slowly gather a sufficient number of ships with each wave of remaining warships and try to break through the defenders' defenses.

In fact, a hundred times lighter.

Because, the enemy is not only the fleet, but also the defense system, and even deploys various special means and so on.

In many cases, the attacker even needs to gather more than 100 times the number of troops to be considered relatively safe.

So, although this third-class corps has already come out before and after fifty waves, one hundred thousand warships.

But in fact, the warships that can still fight at this moment are only worth more than 10,000.

The rest...

Basically, it was destroyed the moment it came out of the passage.

But in any case, this number has slowly accumulated to tens of thousands, isn't it?

This also allows them to destroy more defenders on their lines each time they counterattack.

After all, those Combined I warships on the defensive line ...

But there are no spatial shields!

It's just a hit and a blast!

Although each time it is about enough to destroy thousands of combined warships.

But this also made Luo Yu very heartbroken.

You know, he only has a total of 3 million Joint I warships in his hands.

Moreover, he has to rely on these warships until the arrival of the pioneer fleet.

"Let those 200,000 Combined Type II warships immediately enter the defensive line to enhance the firepower of the defensive line!"

"In the shortest possible time, the growth of the enemy's forces will be suppressed, if not completely suppressed, the growth rate will be slowed down to the greatest extent!"

There was a hint of solemnity on his face.

Luo Yu said clearly.

It's not that he doesn't want to send more warships up and suppress them with absolute firepower.

It's that this line of defense is so big, after all, it's just a passage that can pass through 2,000 warships at the same time.

Around the entrance of the passage, a hemispherical defensive line is arranged at a distance of ten light seconds, and in addition to the position occupied by those defense systems, it can accommodate another 1.23 million warships...

That's the limit.
