The width is 100 light seconds, the height is 30 light seconds, and the depth is 300 light seconds.
This is the only way for the Galactic Center Channel to enter the second main spiral arm.
It is completely a flat channel-like space.
The Viking Defense Line was built here by the Prol Community in more than a year when the Empire attacked the Lane Republic and the Filna Union.
Within this short span of one hundred light seconds, there were gathered 15,000 level-4 civilization main battleships, millions of gunboats modified from civilian spaceships, more than 100,000 large and small defense platforms, and hundreds of war fortresses.
If these forces were placed elsewhere, they would definitely not be a match for the empire's more than 50,000 battleships and millions of affiliated civilization battleships.
But here...
The troops cannot be fully deployed, and the empire's side does not have any advantage, and even has a considerable disadvantage.
After all, the more than 100,000 defense platforms of the fourth-level civilization and the hundreds of war fortresses of the same fourth-level civilization are not just showy.
Of course, it is also possible to force an attack and engage in a war of attrition.
Brown has even done many simulations for this purpose, but the results were not very good.
Although it was successful every time, the one with the smallest casualties required 80% of the attached civilization's battleships and 60% of the empire's main battleships to be consumed before the breakthrough was finally completed.
The key is that even after paying such heavy casualties, the Prol Community managed to escape with 10,000 main battleships and more than 300,000 gunboats converted from civilian spaceships.
This greatly damaged the empire's vitality, and its speed was seriously damaged in the subsequent advancement process.
Not to mention, after learning that the empire has suffered such heavy losses, will the Republic of Lane take the opportunity to reach an agreement with the Association, or will some of the affiliated civilizations defect and re-align...
This is all possible.
At this moment, Brown also regretted that he should not have left only 10,000 battleships and withdrew from the second main spiral arm.
If 15,000 or even 20,000 warships were left behind, although it would reduce the strength of other battlefields, it would only take a little more time and would not allow the Prol Community to make such a good move.
But since a month ago, after receiving Guren's order.
The depression in Brown's heart...
It dissipated directly.
------
Viking defense line.
Inside a giant war fortress.
Command center.
"Warmaster, according to intelligence, the Kerry Empire's fleet of approximately 40,000 main warships has arrived at the exit of the third main spiral arm. It will take at most two months to reach us."
"Let them come. The Viking defense line was set up to bury them. As long as we consume most of the empire's military power here, the entire situation will be completely reversed!"
Vicarlo said nonchalantly.
In this environment and the deployment of the Viking defense line, not to mention directly defeating the empire and its minions, but making them pay a heavy price, I still have great confidence.
The question is just how high the cost is.
Sixty percent?
Seventy percent?
Eighty percent?
still...
Ninety percent?
"Report, it is discovered that the fleet of the Kaili Empire is approaching, in a battle formation, with a number of 10,000, and a distance of 27 light seconds!"
"Um?"
Hearing this, Vicaro looked stunned.
Although he knew that there were 10,000 imperial warships staying on the Galactic Center Passage, he even considered whether he should go out and kill some of them before the main force of the empire arrived.
After all, he now has superior military strength, doesn’t he?
However, these 10,000 warships took the initiative to attack, and they still attacked their own Viking defense line.
Is that guy Brown out of his mind?
"Warmaster, is there a conspiracy in the Kerry Empire?"
On the side, Vicarlo's adjutant was also very surprised and suspected that there was a conspiracy.
Otherwise, it is impossible to explain the current behavior of the Kaili Empire fleet.
"Sound the battle alarm and order all fleets to strictly guard their defense lines and not to attack wantonly."
"No matter what conspiracy they have, as long as we hold the line of defense, any conspiracy is meaningless."
"But if they really dare to attack the defense line, that's just right. Let's treat it as a drill before the war. By the way, it can also weaken some of their troops and create more favorable conditions for subsequent battles."
From a normal perspective, there is nothing wrong with Vicaro's logic.
However, at this moment, a shout suddenly rang out from the command center.
"Report, a large number of gravity waves have been detected, the number is more than 50,000!"
"Impossible, the imperial fleet is right in front of us. Where did they get 50,000 battleships?"
The next moment, just as Vikaro's roar had just ended, a large number of warships continuously arrived at the Viking defense line through the jump.
However, when Vicaro looked through the observation screen and saw what was jumping over...
Somewhat dumbfounded.
Are they all cargo ships?
What is the Kerry Empire planning?
Could it be that these cargo ships are filled with space fighters to activate and disrupt the defense lines, creating opportunities for the main fleet to break through?
But if this is the case, is it too small to underestimate the Viking defense line you have deployed?
"Order all warships and defense platforms to immediately lock on to those cargo ships and destroy them all. At the same time, all fighter groups are dispatched, ready to destroy any enemy space fighter units that may appear."
"Yes, Warmaster!"
The entire defense line, all battleships, and all defense platforms, turned their guns and pointed them at the tens of thousands of cargo ships scattered throughout the defense line, and were soon ready to open fire.
However, they no longer had the chance to fire.
In just one moment, more than 50,000 cargo ships exploded one after another, turning into terrifying energy groups one after another, each covering a range of thousands of kilometers.
The silvery white light completely swallowed up the entire defense line.
Whether it's a battleship, fighter plane, defense platform, or war fortress...
None of them could escape such a blow, and were destroyed one after another, and even turned into dust in the starry sky.
Just like a general cleaning, the entire defense line was completely cleaned. Only a few uncovered corners survived, and some battleships survived.
but...
The number of survivors is less than 2,000.
As for the war fortress, only the one where Vicaro was located was not affected because it was located three light seconds behind the defense line.
But even if he survived, Vicaro was already on the verge of collapse at this moment.
Because, nearly all the combat forces of the Prol Community are on the Viking defense line at the moment...
"The Prol Community... is over!"
Vicaro, whose eyes were blank, finally just uttered this sentence from his mouth.
Although he had a chance to escape at this time, he no longer had the intention.
------
Half an hour later.
After the imperial fleet annihilated all the remaining battleships of the Prol Community and destroyed the war fortress where Vikaro was located...
Go deep into its territory.
And all the way to the capital area of the Purlo Community, the distance of hundreds of light years...
