The battle for Sextant A has lasted for 47 hours.

The number of enemy warships remaining at the entrance of the passage is close to 50,000.

The number of defenders on the defensive line has more than doubled compared to the first day.

"Legion Commander, the losses of the attached civilization fleet have exceeded 900,000, and the reserve fleet has also been consumed by nearly half."

"As the rate of subsequent losses continues to increase, we will exhaust all remaining reserve forces within 12 hours."

"Should we send our three legions up now?"

In the bridge, the adjutant said anxiously.

However, Luo Yu shook his head.

"It's not the right time yet. The number of warships gathered by the opponent at this time is close to 50,000. Sending only 30,000 Pangu-class ships is of little significance, and may even cause heavy casualties."

Luo Yu didn't feel sad at all about how many battleships were lost in the affiliated civilization.

But the Federation's own fleet is very particular about when to attack.

It is necessary to ensure that the maximum effect is obtained with the minimum loss.

And if you want to do this, you must clear the channel entrance and return everything to the original state without holding on for too long.

After all, even if 30,000 Pangu-class ships are sent up, and the number of enemy warships remaining is reduced to zero, it is impossible to say that all enemy ships can be completely annihilated in every wave, making it impossible for the opponent to gather strength at the entrance of the passage.

As time goes by, losses will continue to rise as the enemy retains more warships.

"Notify the Stellar Array Cannon to be prepared and the attack will begin in 57 minutes!"

After looking at the time, Luo Yu ordered.

"Yes, legion commander!"

------

At the same time.

It is about 1au away from the battlefield at the entrance of the passage.

At this moment, the scene here is very strange, with hundreds of stars arranged at equal distances into a huge triangle.

In the center of this triangular array, there is also an unknown triangular hollow device.

Apart from the different shape, it feels somewhat similar to a star ring.

This is a one-time tactical-grade weapon developed by the Federation in the past few years.

Official code name: fs105, Stellar Array Cannon!

Why is it said to be a disposable tactical-grade weapon?

Because after it is activated, it will continuously extract the energy of all the stars on the triangular array, and release the huge energy in the form of radiation through the irradiation port in the middle of the array.

Theoretically, these 369 stars can support continuous illumination for up to one hour, and the illumination range is large enough to cover all enemy fleets at the entrance of the passage.

However, after one hour of illumination, these 369 stars will all be extinguished because their energy has been drained.

The irradiation port located in the center will also be overwhelmed and cannot be used again.

It is a proper disposable weapon and can only be used in defensive warfare.

After all, if you go on an expedition, you can't bring hundreds of stars with you, right?

You know, the Federation spent a lot of effort to get these stars here three years ago.

------

The 50 minutes passed quickly.

"Legion Commander, the number of enemy ships remaining has reached 48,927."

"Instruct the star array cannon to start, and at the same time, tell the defenders on the ray to get out of the way immediately!"

"Yes, legion commander!"

After a while, part of the fleet on the defense line had received orders from the commander-in-chief at the rear.

The command is simple, give up the attack route as quickly as possible.

Give way to attack?

What's the meaning?

No one quite understands.

However, the good thing is that along with the order, there was also a tactical diagram.

In the dynamic diagram, somewhere behind the defense line, an attack suddenly shot out, and the place where this attack passed was exactly where their defenders were.

After reading this, no one still knows what kind of super weapon the Federation is going to use.

Without any hesitation at the moment, he quickly gave orders to all the warships in his fleet that were on the attack route to avoid the marked attack route as quickly as possible.

A few minutes later.

Hundreds of light seconds away, as the entire system started up, the rays of 360 stars arranged in a triangle became increasingly bright.

Then, each star poured out a huge amount of energy, which instantly hit the central hollow triangular illumination port at a speed similar to the speed of light.

"50%..."

"60%..."

...

"99%, 100%!"

"The stellar array cannon, the energy of the irradiation port has reached the critical point, and the irradiation preparation is completed!"

"Start irradiation!"

"Yes, star array cannon, irradiation begins!"

The next moment, he has reached the spiritual realm point and continues to vent his energy.

It was as if a valve had been suddenly opened, and it suddenly spurted out, blasting all the way towards the entrance of the passage hundreds of light seconds away.

At this time, both the defenders on the defense line and the third-class Silver Light Empire Legion at the entrance of the passage had all detected this terrifying and incoming attack.

"Legion Commander, it seems that the opponent has detected the stellar array cannon and no longer holds the bridgehead at the entrance of the passage. Instead, it is trying to break out to the side."

"Order all our fleets to dispatch to increase their firepower and confine them to the center of the defensive circle."

"Yes, legion commander!"

After the adjutant retired, Luo Yu looked at the real-time three-dimensional model of the battlefield again.

The direction where the stellar array cannon is deployed is actually the front of the Silver Empire's Third Legion after they exit the passage.

Therefore, the only way to avoid such a blow is to break out to the side.

Of course, the cosmic battlefield is not flat, but three-dimensional.

Therefore, the side here does not refer to the left or right, but a 360-degree circle around it, no matter which direction it is.

In short, as long as it is not directly in front of the fleet, it will be fine.

As for the stellar array cannon, it is not a space weapon after all, and its attack speed cannot exceed the speed of light.

The distance of 1 au is 499 light seconds, which is close to 500 light seconds.

In other words, based on the distance calculation here, it takes more than eight minutes from the start of irradiation until it hits the target.

What Luo Yu has to do now is to ensure that within these eight minutes, he pins the opponent firmly in the center of the encirclement and prevents them from having a chance to break out.

To this end, he sent out all three standard fleets of the First Legion of the Defense Fleet.

Two of them are deployed in the direction of the opponent's current breakout to increase firepower.

The other branch is deployed in other directions.

in case!

------

At this time, the third-class army of the Silver Light Empire was also trying its best.

They simply didn't care about the losses, didn't pay attention to the formation, and just rushed to kill.

He looked like he would not hesitate to kill a hundred enemies and lose ten thousand to himself.

After all, although they wanted to rush and attack in one direction, they were still within a hemispherical encirclement, and they were naturally unable to escape from the all-round crossfire.

Originally, it would have been better for them to gather the fleet at the entrance of the passage and set up a defensive formation.

But now they are all rushing in the same direction, even ignoring the fleet array, and the result can be imagined.

If there were only those fleets belonging to attached civilizations, it would really be possible to overwhelm the nearly 50,000 battleships.

However, after 20,000 Pangu-class battleships entered the defense line, it was unrealistic to rush out in just a few minutes.

Until eight minutes later.
