This time, the Federation is not as good as the people sent by these civilizations as before.

Instead, they were directly imprisoned.

As for how to make them willingly contribute to federal scientific research after the captivity.

Jiang Xingchen doesn't need to worry about this, Xue Qiang and the intelligence department he leads will naturally be responsible.

------

New Federal Calendar 1628.

The supply of Chiyou particles was cut off in less than three years.

The entire alliance had already depleted all the Chiyou particles in reserve, and it quickly collapsed.

By 1631 of the New Federation Calendar, one of the crossing points was completely lost, and countless Pretender warships poured into Livione.

Subsequently, the other three crossing points also collapsed quickly because of the enemy on their backs.

The entire alliance began to enter the stage of cosmic defense warfare.

But this is doomed to be futile, and at most it will only delay the time of destruction a little.

It was not until three years later in the new federal calendar in 1634.

All civilizations in Livione have been wiped out, and countless lives have been taken over by the Pretenders.

However, due to the resistance to the end, the Pretender was not able to get much reinforcement from Livione.

If in that sense, they are failures.

After all, in order to take Livio, the Pretenders lost at least 4-5 of the entire forces of the Black Chamber Realm.

But just as they are frantically searching for the survivors of various civilizations in one universe after another, and continue to parasitize, they don't know...

Before the crossing point of its Dot Black Cavity Realm, the Federation's army of more than 300 billion warships was ready to go.

The 50 billion main warships of the Federation and the 250 billion auxiliary civilization warships have formed an innumerable fleet phalanx, and the momentum is extremely huge.

"Start dropping the Chiyou Particle Compression Bomb!"

"After the launch, the first to tenth attack clusters of the affiliated civilizations will enter in order, and after arriving on the other side, they will quickly complete the cleanup operation of the surrounding pretenders, and ensure the safety zone of at least 500 standard black cavity units!"

Inside the bridge, Jiang Xingchen waved his hand and gave the order to start the battle.

The next moment, everyone was busy, constantly conveying orders one after another.

This time, Jiang Xingchen will let the affiliated civilization take the lead.

And the reason why I didn't do that last time was because the number of weapons of Chiyou Particle was limited at that time, and it only equipped tens of billions of federal capital warships, and there were no subordinate civilizations at all.

In this case, letting them take the lead is no different from sending them to death.

The point is, it hasn't worked yet.

But this time is different, whether it is the Federation fleet or the affiliated civilization fleet, after nearly a hundred years, all warships are equipped with the superray stream of Chiyou particles.

In terms of killing the Pretenders, it is no different from the Federation's main fleet.

In this case, there is naturally no need to let the Federation soldiers take risks.

Cross the other side of the point.

The pretender is naturally aware of the existence of its Dotney Federation, because the first thing they did after taking Livio was to set up defenses here.

More than 100 billion warships blocked the outside of the crossing point.

But they didn't realize one thing.

That is, after nearly a hundred years have passed, is there no change in the Federation's weapons against the pretenders as they were a hundred years ago?

Balls with a diameter of about 50 meters continue to emerge from the crossing point.

And before the pretender had time to fire, it was detonated as soon as possible.

Compared to when the Federation attacked its Dort Black Chambers a hundred years ago, each of today's Chiyou Particle Compression Bombs has a larger reserve of particles, due to the use of spatial expansion technology inside.

You may only see a 50-meter-diameter sphere, but the actual particle reserves are more than 10,000 times, and all of them are compressed reserves.

According to the Federation's calculations, 1 million such bombs can completely cover the surrounding 300 standard black cavity units in just five minutes, and ensure that they still have a lethal particle density to the pretender.

Even more than 300 standard black chamber units can ensure that within 500 standard black chamber units, the particle density is enough to temporarily paralyze the pretender.

This kind of weapon, even for a rudimentary black cavity civilization, did not pose any threat.

But for the pretenders ...

But it is undoubtedly a super killer.

In the first minute after the Chiyou Particle Compression Bomb was successfully detonated, all the pretenders were killed in dozens of standard black cavity units around the crossing point, and the battleship became unmanned, as if paralyzed.

At the same time, the First Attack Group of the Federation-affiliated Civilization began to arrive one after another, and quickly rushed outward.

After all, although the pretenders on these ships have been destroyed, the ships do not pose a threat.

But...

It's in the way!

If you don't blast them out, the warships that continue to arrive behind will soon run out of space for assembly.

The holding particles are constantly spreading outwards at an extremely fast speed.

And the Federation Affiliated Civilization Fleet is also constantly arriving.

Under the two phases, a safe zone is immediately formed outside the crossing point.

But this was not enough, because Jiang Xingchen's order was to establish a safe zone of at least 500 standard black cavity units.

So, they have to keep rushing out.

The real battle will not begin until these subordinate civilization fleets have been killed to 500 Black Chamber units.

Because after this distance, the Chiyou particles, which are desperately spreading outward, can no longer threaten the pretender.

After all, as the diffusion range increases, so does the particle density.

------

Three hours later.

500 Black Chamber Units from the crossing point.

The firefight begins!

The disguiser who knew that the cell needle was useless did not continue to engage in this useless work, but directly attacked with conventional fire.

I have to say that with such a fight, the casualties on the side of the affiliated civilizations are really large.

After all, the Federation's latest generation of combined warships is the level of the primary black chamber civilization, and the pretenders have a large number of medium or even high black chamber civilization standard warships.

But in fact, although the casualties of the Federation-affiliated civilizations are large, the casualties on the side of the pretenders are still more than five times.

Who made the Black Cavity Shield have no blocking effect on the Chiyou particles?

So, later, the Pretender's fleet simply turned off the Black Chamber's shield and replaced it with a particle barrier.

Because these two goods will interfere with each other and cannot be opened together.

You must know that the essence of the black cavity shield is the black cavity particles, and the existence of the particle isolation barrier will naturally cause the same isolation effect on the black cavity particles.

However, even so, the effect is still not very good, and even the casualty ratio is more exaggerated.

This is because the particle barrier is not defenseless.

For example, if a warship of a subordinate civilization has about 100 naval guns on it, originally, according to the standards of the primary black cavity civilization, if you want to burst the black cavity shield of the pretender warship, I am afraid that you need to hit hundreds of rounds.

But when the pretender removes the Black Cavity Shield, it can give you a direct dry explosion with one shot.

Even a combined warship of a subordinate civilization can lock on to 100 targets at the same time and attack at the same time.

That's where it gets interesting.

The superray stream of Chiyou particles will kill 2 or 30 ships as soon as they pass by.

But now it's likely that a wave of attacks will kill you 5, 60 or even nearly 100 ships.

So, while the pretender was able to defend against the superray stream of Chiyou particles, the casualties were much greater.

As a last resort...

After ten minutes of fighting, all the Pretender battleships could only close the particle isolation barrier ...

The Black Chamber's Shield has been reopened!

And the attached civilization fleet also used the Chiyou particle weapon once again to launch an offensive.
