In the Ring Silver Heart Channel, between the first main spiral arm and the second main spiral arm, on the defense line on the side of the Vera Alliance, an abnormally ten-billion-level battle is being launched at this moment.

On one side is the garrison on the defense line of the Vera Alliance's Silver Heart Passage, with a strength of 10 billion rank 4 civilization warships.

On the other side is the expeditionary force of the Zola Alliance, with a strength of 48 billion fourth-class civilized warships and 2 billion fifth-class civilized warships.

The various colored energy bombs and beams of light in the entire channel were intertwined, and even the dark and lightless channel space had been completely illuminated.

Due to the size of the Silver Heart Channel, only 10 billion warships on each side were directly engaged head-on, and this number alone had completely filled the cross-section of the entire channel.

The difference is only that there are still 40 billion warships behind the Zola Alliance, and once the battleships are damaged on the front line, there will be warships to fill the vacancy immediately.

On the other hand, the defenders of the Vera Alliance do not have any back strength, and once a gap is made in the entire defense line, they can only squeeze out some of the warships in other positions to fill the gap.

Because of this, when this offensive and defensive battle was carried out on the tenth day, the defense line on the side of the Vera Alliance was much looser than at the beginning, and the warships had lost as much as 1.5 billion.

And because the Zola Alliance side has enough back strength, it can immediately fill up as much as it loses, so it is still 10 billion warships, maintaining the largest firepower projection!

Inside the battle star, Oleg looked at the battle situation in front of him and frowned slightly.

If he continues to fight like this, let alone three months, it would be good if he could hold on for a month.

People have enough back strength, and the people in front are tired, and they can pull out 10 billion warships at any time in the back and gradually replace the warships in front to rest.

And what about your own side? It's been ten days! All the soldiers haven't closed their eyes for ten days!

Although most of the people in these Vera Alliances are not as fragile as humans, and they can't bear it if they don't fit their eyes for a few days, they are also very tired after ten consecutive days of high-intensity fighting!

Although the defensive line was a little looser, for a short time, Oleg was able to hold on until the fifteenth day after the battle.

At this moment, there are about 7.5 billion remaining warships on the Vera Alliance defense line, and at the same time, the remaining warriors have also entered a period of extreme fatigue, and the combat effectiveness of the entire garrison fleet has been greatly reduced.

And the commander of the expeditionary force of the Zola Alliance keenly discovered this, and very decisively ordered the killer weapon of the expeditionary force to let the killer 2 billion warships of the fifth-level civilization of the Republic of Buckland attack immediately, break through from the center of the enemy's defense line, and spread out behind the enemy, forming a two-sided attack with the frontal attacking fleet!

An hour later, inside a battle star on the Villa defensive line.

"Grand Commander Oleg, the attack array of the Zola Alliance has changed, and the warships in the central part are retreating!"

The adjutant's report immediately swept away the fatigue on Oleg's body, and he stared at the tactical image for a long time.

"It's not good, the battleship group in the center of the opponent is not retreating, but giving way, the Zola Alliance is going to make a killer move! It is highly likely to be a battleship of the Republic of Buckland, a fifth-level civilization! ”

Oleg immediately analyzed the anomaly of the Zola Alliance, if it was in the past, it would not be a big problem, soldier to soldier, general to general!

You send a fifth-level civilization warship, and I will also send a fifth-level civilization battleship!

But what about now? The problem is that all the Villa Federation legions have been transferred to the main battlefield, and now only the fourth-level civilization legions under the Vera Alliance are here.

However, fortunately, although the fifth-level civilization warships have been transferred, the defense facilities on the defense line are not the things of the fourth-level civilization, but the Vera Federation with the technology of its own fifth-level civilization.

"Quick, immediately mobilize all the defensive platforms on the defensive line, prepare to concentrate firepower to block the opponent's central breakthrough, let the fourth-level civilization warship group in the middle get out of the way, and in the face of the fifth-level civilization warship, they stay and just send them to death!"

"Understood!"

However, the order was given a little late, and half an hour later, when the fleet in the center of the defense line had just withdrawn halfway, the 2 billion warships of the Republic of Buckland on the opposite side had already been killed in an assault formation!

The fourth-level civilization warships that had not yet completed their evacuation began to fire while evacuating, in an attempt to delay the opponent's breakthrough speed.

It's a pity that all this is meaningless, the weapons of the fourth-level civilization can't cause any damage at all for the space shield of the fifth-level civilization!

I saw that not only the energy bomb, but also the energy beam, hit these battleships of the Republic of Buckland, as if they were swallowed by something, and all the attacks disappeared in an instant, this picture is quite weird!

"Let those battleships leave me as quickly as possible, don't get in the way there, I said it, they have no effect in the face of fifth-level civilization warships!"

"Yes, Grand Commander Oleg!"

But the 2 billion warships of the Republic of Buckland have already been entangled, how can these fourth-level civilization warships be withdrawn if they want to?

Looking at this picture, Oleg knew that these fleets were hopeless!

"Change the order and directly let all the defensive platforms fire with all their might at the enemy fleet in the central assault!"

Oleg gritted his teeth and ordered to the adjutant!

"Great Commander, there are still more than 500 million of our warships there!"

"Shut up, if we don't fire now, we won't lose 500 million, but the entire defense line has collapsed, fire immediately!"

"Yes, Grand Commander Oleg!"

was yelled at by Oleg, and the adjutant also came to his senses, and he understood the reason, but he had to attack with hundreds of millions of his own warships, and normally speaking, he would always hesitate.

When the order was given, a few seconds later, all the defense platforms immediately began to attack!

Instead of energy projectiles or energy beams, these platforms are firing a physical projectile, somewhat similar to a rail cannon.

But it is very different from the rail cannon, the rail cannon shoots out a simple physical projectile, and the defense platform of the Vera Alliance shoots out a completely different, the internal structure of the projectile is extremely complex, and at the moment of hitting the current one, the front end of the projectile will release an ultra-small single forward space barrier!

When the projectile hits the warship of the Republic of Buckland, the first thing that comes into contact with its space shield is this one-front space barrier, which is used to cancel out and destroy the opponent's space shield, so that the projectile can directly rush into this small gap that was opened before the opponent's space shield recovers.

This is also a common attack method when fighting between level 5 civilizations, which can effectively attack warships holding space shields.

With a large number of attacks coming, the speed of the surprise attack of the warships of the Republic of Buckland suddenly stopped, and under this wave of attacks, 1 million warships were destroyed.

However, the warships of the Republic of Buckland were fifth-level civilized warships, so they naturally would not be beaten so obediently, and immediately ignored the fourth-level warships around them, but launched a fierce attack on the defense facilities on the Vera Empire's defense line!
