Around the silverheart channel, between the first main arm and the second main arm, on the defensive line of villa alliance side, there is an extraordinary 10 billion level war at the moment.

One side is the garrison on the silver channel defense line of Vera alliance, with a force of 10 billion class IV civilized warships.

On the other side is the Zora alliance's expeditionary force, with a force of 48 billion level 4 civilized warships and 2 billion level 5 civilized warships.

All kinds of color energy bombs and light beams crisscross each other in the whole channel, and even the dark channel space without light has been completely illuminated.

Due to the size of the Yinxin channel, only 10 billion warships from each side were engaged in direct combat. This number alone has completely filled the cross section of the whole channel.

The difference is that there are still 40 billion warships behind the Zora alliance. Once the warships on the front line are damaged, there will be warships to fill the vacancy immediately.

As for the defenders of villa, they don't have any back strength. Once there is a gap in the whole defense, they can only squeeze some warships from other positions to fill the gap.

Because of this, when the offensive and defensive war went on to the tenth day, the defense line on the side of villa alliance was much looser than at the beginning, and the warships had lost as much as 1.5 billion.

The Zora alliance side has enough back strength to make up for the loss immediately, so it is still 10 billion warships, maintaining the largest fire projection!

Inside the battle star, Oleg frowned at the battle ahead.

If we play like this, let alone three months, it's good for him to hold on for one month.

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

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 Vera league are not as vulnerable as human beings and can't bear to eat if they don't sleep for a few days, they are very tired after ten days of high-intensity fighting!

Although the defense line was a little loose, Oleg could maintain it for a short time until the 15th day after the war.

At the moment, there are about 7.5 billion warships left in the villa alliance defense line. Meanwhile, the remaining soldiers have entered a period of extreme fatigue. The combat effectiveness of the whole garrison fleet has been greatly reduced.

The commander in chief of Zora's expeditionary army was keen to find this point, and very decisively ordered that the expeditionary army's Killer 2 billion warships of the Republic of Buckland, a class five civilization, should attack immediately, break through from the center of the enemy's defense line and launch behind the enemy's back, forming a situation of double attack with the front attacking fleet!

An hour later, a star in villa's defence.

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

The adjutant's report immediately wiped out Oleg's tiredness, staring at the tactical video for a long time.

"No, the warships in the center of the other side are not retreating, but making way. Zora alliance is going to use its mace! It's very likely to be the warship of the Republic of Buckland, a class five civilization! "

Oleg immediately analyzed from the abnormality of Zola alliance. If it was in the past, it was not a big problem. Soldiers to soldiers, generals to generals!

You send out the warships of level five civilization, I also send out the warships of level five civilization!

But now? The problem is that all the Federation of villa have been transferred to the main battlefield, and now there are only four civilization legions of villa alliance.

Fortunately, though the class five civilization warships have been transferred, the defense facilities on the defense line are not of class four civilization, but made by the Federation of villa with its own class five civilization technology.

"Quick, immediately mobilize all the defense platforms on the defense line, prepare to concentrate fire to block the other party's central breakthrough, and let the class IV civilized warships in the central part move away. In the face of class V civilized warships, they just stay and die!"

"I understand!"

However, the order was issued a little later. Half an hour later, when the fleet in the middle of the defense line had just withdrawn, the two billion Buckland Republic warships opposite had already been killed in a shock formation!

The class IV civilized warships, which have not yet completed the evacuation, began to fire while evacuating, in an attempt to delay the other party's breakthrough speed.

Unfortunately, all this is meaningless. Weapons of level 4 civilization can't cause any damage to the space shield of level 5 civilization!

It's not only the energy bomb or the energy beam that strikes these warships of the Republic of Buckland. It's like being swallowed by something. All the attacks disappear instantly. This picture is quite strange!

"Let those warships leave me as soon as possible. Don't get in the way. They have said that they have no effect in the face of class V civilized warships!"

"Yes, commander Oleg!"

However, the 2 billion Buckland Republic warships have been entangled. Can these class IV civilization warships withdraw if they want to?Looking at this picture, Oleg knows that these fleets are hopeless!

"Change the order, direct all defense platforms to open fire on the enemy ships in the central penetration!"

Oleg clenched his teeth and ordered to the adjutant!

"Commander in chief, there are more than 500 million warships out there!"

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

"Yes, commander Oleg!"

When Oleg yelled at him, the adjutant also woke up. He also understood the truth. He just wanted to attack with hundreds of millions of his own warships. Normally, he would always hesitate.

When the command is issued, a few seconds later, all the defense platforms immediately began to attack!

These defense platforms are not energy bombs or energy beams, but a kind of solid projectiles, which are somewhat similar to rail guns.

However, it is quite different from the railgun. The railgun only shoots a simple solid projectile, while the defense platform of Vera alliance shoots a completely different one. The internal structure of the projectile is extremely complex. At the moment of hitting the current one, the front end of the projectile will release a super small one-way front space barrier!

When the projectile hits the warship of the Republic of Buckland, the first contact with its space shield is the one-way front space barrier. Its function is to counteract and destroy each other's space shield, so that the projectile can directly rush in from the small opening before the other's space shield recovers.

This is also a common way of attack when fighting among the five civilizations. It can effectively attack warships with space shields.

With the advent of a large number of attacks, the assault speed of the Buckland Republic warships was greatly reduced. Under this wave of attacks, one million warships were destroyed.

However, the warships of the Republic of Buckland were class five civilization warships. Naturally, they would not be beaten so obediently. They immediately ignored the class four warships around them, but launched a fierce attack on the defense facilities of the Vila empire!
