It has been two years and eight months since the Starry Sky Zerg retreated into the Death Nebula.
At this moment, the atmosphere along the entire defense line was a bit tense.
Just three days ago, the monitoring devices Kyle deployed in the passage detected the appearance of a large number of worm mounds.
However, it didn't take long for all these monitoring devices to be destroyed.
Although it is impossible to determine how many troops the Starry Sky Zerg dispatched this time, it was confirmed before the monitoring device was destroyed that there were already more than 5,000 insect mounds, and the follow-up ones are still arriving one after another.
This gave everyone a bad feeling.
After disappearing for nearly three years, how far has the strength of the Starry Sky Zerg expanded?
------
"How's it going, Xingchen?"
In the bridge of the Star, Mu Zhengfeng's figure was projected in front of Jiang Xingchen.
After hearing that Insect Mound had started taking action, he immediately came to inquire about the situation.
"Honestly, it's not a good situation."
"How to say?"
After hearing what Jiang Xingchen said, Mu Zhengfeng also asked quickly.
After all, whether this line of defense can be held is also very important to mankind.
Nowadays, the handover of humans on the first and fourth main spiral arms is in progress, and the handover of the second and third main spiral arms cannot begin until the Kerry Empire has captured them.
This means that in the entire transaction, the handover of the main spiral arm to humans will not be completed until three to 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 humans.
"Commander, you have also seen how the defense line here is arranged. 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 entrance of the passage with hemispherical crossfire when it first appears, making it impossible to expand."
"On the surface, there is nothing wrong with this arrangement, and I can also understand the reason for Kyle's arrangement. After all, his subordinates are all second- and third-level civilizations, and the battleship weapons are too rubbish."
"but..."
"This also has three disadvantages."
"The first one is that because the distance is too close, the fleets on the defense line cannot be fully deployed. A hemispherical defense line with a radius of one light second will not be able to actually participate in the firepower output, with no more than 3 million warships."
"The second is that once we fail to completely suppress the Starry Sky Zerg and let them rush out of the channel, such a close distance will also shorten the Zerg."
"The last one is that Kyle seems to be too confident in the super defense line he has built..."
Hearing this, Mu Zhengfeng nodded.
Jiang Xingchen is right. The tactic of blocking the door at close range is generally a very effective method.
But the premise is that your firepower must be enough to suppress the enemy.
Yes, the key lies in the word suppression.
To put it simply, your firepower must be so powerful that they cannot rush out and can only be blocked at the entrance of the passage.
But Kyle overlooked one very important thing.
In this special environment, three million battleships and all-round crossfire can definitely beat any civilization in the galaxy to doubt.
No matter which one of the four major civilizations.
But the enemy is not technological civilization, but the starry sky Zerg.
Just say a little...
Can those second- and third-level civilization battleships defeat the Baneling Tombs?
Can't hit it!
Since it can't be destroyed, how can it be suppressed?
Not to mention, whether there are only 3 million warships at this distance can suppress the overwhelming sea of insects.
Therefore, the way this defense line is deployed has a huge loophole from the beginning.
"Then what are you going to do?"
"If it really doesn't work, just withdraw it. If we don't do this deal, we won't do it. Humans on the main spiral arm, we will think of other solutions later."
After thinking for a while, Mu Zhengfeng said.
However, Jiang Xingchen shook his head.
"No, we can't leave hidden dangers in the future. Since we finally reached an agreement, we must take advantage of this moment to rescue everyone."
"Otherwise, when we return to the Milky Way in the future, that guy Guren will really imprison hundreds or even thousands of humans on each battleship. How can we fight this battle?"
"As for the defense line, I will find a way."
Jiang Xingchen shook his head and said.
Don't doubt it, Guren can say this kind of thing, and he will definitely do it.
"Okay, if you insist, but if things go wrong, you have to withdraw."
"We can't afford to lose a battle star, let alone you!"
Seeing Jiang Xingchen's determined expression, Mu Zhengfeng said no more.
Anyway, with the capabilities of the Star, even if an uncontrollable situation occurs 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 in our ability to withdraw. Not only the Star, but also other battleships in the fleet."
"Well, when others say this, I only think that they are expressing their determination, but I still believe your words."
Mu Zhengfeng nodded and said.
------
A few hours later.
Along the entire defense line, alarms sounded suddenly in all battleships.
The Starry Sky Zerg are finally here!
Before they even showed up, Kyle had already given the order to fire.
At the forefront of the defense line, more than three million warships were deployed in a hemispherical shape, and began to pour out firepower in a cross-fire manner.
Each wave is composed of tens of millions of railgun solid projectiles, densely packed towards the entrance of the passage.
Even if the distance is one light second, it will take about three minutes for the projectile to arrive using a railgun.
Therefore, if you wait for the Star Zerg to appear from the passage before firing, it will definitely be too late.
The time was calculated very accurately. When the first wave of projectiles converged at the entrance of the passage, dozens of insect mounds just flew out of it.
Immediately, the overwhelming projectiles swept away the fighting insects around these insect mounds and bombarded the insect mound itself.
Looking at the situation, every insect mound was probably hit by at least tens of thousands of rounds.
Of course, the power of the railgun is only so small, and it is almost impossible to blow up the insect mound.
It’s not that the battleships of the second and third level civilizations can’t take down the worm mounds, it’s just that they’re very difficult to take down.
Because their attacks are like scraping for Chongzhong.
Even the wave of attacks just now probably plowed through the surface of the insect mound and shaved off several meters of thickness.
But this damage is really nothing to an insect mound that is over a thousand meters long, let alone those that are thousands of meters or even tens of thousands of meters away.
The next moment, a black mist appeared at the entrance of the passage.
Ah no, this is not a black mist, but a black sea of insects.
Countless war insects are flying out from the insect mound and joining the insect sea, making it larger and larger.
At the same time, this sea of insects has also become a city wall of flesh and blood.
Before it is completely broken up, it will be difficult for the fleets on the defense line to attack the insect mound again.
But it is very difficult to disperse the sea of insects.
At least, it is so difficult for second- and third-level civilizations.
You know, railguns are no better than energy weapons, they can directly blast war bugs into dregs.
Railgun projectiles mostly cause penetrating damage to war bugs, and even if they don't hit their vital points, they won't be able to kill them successfully.
And even if they are successfully killed, those dead war insects can still maintain relatively complete bodies.
In other words, it turned into a corpse, but it was still fending off attacks for the insect mound behind it.
Therefore, this city wall of flesh and blood will only get bigger and bigger, and...
