Late Dark Age 413.

It has been two years and eight months since the Starry Sky Zerg retreated into the Death Nebula.

At this moment, the atmosphere of the entire defense line is a little unruly.

Just three days ago, Kyle's surveillance devices deployed in the passage detected the presence of a large number of mounds.

However, it didn't take long for all of these surveillance devices to be destroyed.

Although it is impossible to determine how many troops the Starry Sky Zerg has dispatched this time, as far as the monitoring device was destroyed, it has been confirmed that there are more than 5,000 worm mounds, and the follow-up is still arriving.

This gave everyone a bad premonition.

After disappearing for nearly three years, how much has the strength of the Starry Sky Zerg swelled?

------

"How's it going, Xingchen?"

In the bridge of the Xingchen, Mu Zhengfeng's figure was being projected in front of Jiang Xingchen at this moment.

As soon as he heard that the insect mound had started to act, he immediately came to inquire about the situation.

"To be honest, it's not that good."

"How?"

Hearing Jiang Xingchen say this, Mu Zhengfeng also hurriedly asked.

After all, whether this line of defense can be held is also very important for human beings.

Now, the transfer of humans on the first and fourth main spiral arms is underway, and the second and third main arms will not be able to start until the Kairi Empire takes them.

That is to say, in the entire transaction, the transfer of the main spiral arm human will not be completely completed until three or five years later.

And if the Starry Sky Zerg completely breaks out of the nebula, it will inevitably affect the second half of the transaction.

That's tens of billions of human beings.

"Commander, how the defense line here is arranged, you can also see, the entire defense line is only one light second away from the exit of the passage."

"Although, this deployment can suppress the Starry Sky Zerg at the mouth of the passage with hemispherical crossfire when it first appears, making it impossible to deploy."

"On the surface, there is no problem with this arrangement, and I can understand the reason for Kyle's arrangement, after all, all the subordinates are second- and third-level civilizations, and the weapons of the battleships are too rubbish."

"But..."

"There are also three drawbacks to doing so."

"The first is that because the distance is too close, the fleet on the defense line will also not be able to fully deploy, and the hemispherical defense line with a radius of one light second will not actually participate in the firepower output, and it will not exceed 3 million warships."

"The second is that once you can't completely suppress the Starry Sky Zerg and let them rush out of the passage, then such a close distance will also shorten the Zerg."

"The last one is, Kyle seems to be building a super line of defense against him... Too confident. ”

Hearing this, Mu Zhengfeng nodded.

Jiang Xingchen is right, the tactic of blocking the door at close range is normally a very effective way.

But only if you have enough firepower to suppress the enemy.

Yes, the key is in the two words of suppression.

To put it simply, your firepower must be so strong that they can't rush out, and they can only be blocked at the entrance of the passage all the time.

But Kyle overlooked one important thing.

In this special environment, three million warships, all-round crossfire, can definitely beat any civilization in the galaxy into doubt.

Even if it's one of the four major civilizations.

But the enemy is not a technological civilization, but a starry sky zerg.

Just one thing...

Those second- and third-level civilization warships can blow up insect mounds?

Don't blow it up!

Since it can't be exploded, how can it be suppressed?

Not to mention, with only 3 million warships at this distance, can it suppress the overwhelming sea of insects.

So, the way this line of defense is deployed, there is this huge hole in the way it is deployed from the beginning.

"And what are you going to do?"

"If it really doesn't work, just withdraw it, if you don't do this deal, you won't do it, the humans on the main spiral arm, we can't think of other ways in the future."

After thinking for a while, Mu Zhengfeng said.

However, Jiang Xingchen shook his head.

"No, we can't leave hidden dangers in the future, and since we have finally reached an agreement, we must take advantage of this time to rescue everyone."

"Otherwise, when we return to the galaxy in the future, that guy from Gruen is really locked up hundreds or thousands of humans on each warship, how can we fight this battle?"

"As for the defensive side, I'll figure it out."

Shaking his head, Jiang Xingchen said.

Don't doubt it, this kind of thing can be said and definitely done.

"Okay, since you insist, but if the situation is not right, you must withdraw."

"We can't afford to lose a single Battlestar, and we can't afford to lose you!"

Looking at Jiang Xingchen's firm expression, Mu Zhengfeng didn't say anything more.

Anyway, with the ability of the Xingchen, even if there is an uncontrollable situation on the battlefield, if Jiang Xingchen wants to withdraw, there should be no problem.

"Don't worry, Commander, no matter how bad the situation is, I am still confident that I will withdraw, not only the Star, but also the other warships in the fleet."

"Well, when others say this, I only think he is showing his determination, but I still believe your words."

Nodding, Mu Zhengfeng said.

------

Hours later.

Along the entire defensive line, the sirens sounded in all the battleships.

Starry Sky Zerg, it's finally here!

Before they could even be seen, Kyle gave the order to fire.

At the forefront of the defensive line, more than 3 million warships were deployed in a hemispherical shape, and began to pour fire frantically in the form of crossfire.

Each wave was a physical projectile of tens of millions of railguns, densely enveloping the mouth of the channel.

Even if it is a distance of one light second, it will take about three minutes for the projectile to reach it with the help of a railgun.

Therefore, if you wait for the Starry Sky Zerg to appear from within the passage before firing, it will definitely be too late.

The time was calculated very accurately, and when the first wave of projectiles converged at the mouth of the passage, dozens of mounds flew out of it.

Suddenly, the overwhelming projectiles directly swept away the war insects around these insect mounds, and bombarded the body of the insect mounds.

Looking at this situation, I am afraid that every insect mound has been hit by at least tens of thousands of shots.

Of course, the power of the railgun is only like that, and it is almost impossible for such a thing as exploding the insect mound.

The warships of the second and third civilizations are not that they can't kill the worm mound, but it's just that it's difficult to take them out.

Because of their attack, for the mound, it is like scraping.

Even the wave of attacks just now probably ploughed the surface of the mound, cutting off the thickness of several meters.

But this damage is really nothing for a worm mound of thousands of meters, let alone those worm mounds of thousands or even tens of thousands of meters.

The next moment, a black fog appeared at the entrance of the passage.

Ah no, this is not a black fog, but a sea of black and oppressive insects.

Countless war insects are constantly flying out of the worm mound and joining this sea of worms, making it bigger and bigger.

At the same time, this sea of insects has also become a wall of flesh and blood.

Until it is completely scattered, it will be difficult for the fleet on the defensive line to attack the mounds again.

But it is very difficult to break up the sea of worms.

At least, that's how difficult it is for a second- or third-tier civilization.

You know, the railgun is not comparable to energy weapons, and can directly blast war insects into slag.

Most of the projectiles of the railgun are penetrating wounds for war insects, and they can't even be successfully killed if they don't hit the vital point.

And even if they were successfully killed, those dead war insects could still maintain a relatively intact body.

In other words, turned into corpses, but also fended off the attack of the mounds behind.

Therefore, this wall of flesh and blood will only get bigger and bigger, and...

Thicker and thicker!
