As for the current stealth technology and anti-stealth technology in the star refuge.
Also by the top local scientists of the earth civilization.
And the top scientists from those star systems surrendered to the earth civilization and were willing to become the subsidiary civilization of the earth civilization.
Under the research and development team formed together day and night.
Finally a breakthrough has been made.
Now, how good is the stealth technology in the star shelter?
Even if it uses a super-power energy detection radar with a hundred times the basic order of magnitude.
Or the most advanced anti-stealth energy detection radar of each civilization.
Close to the star refuge within one million kilometers.
Carry out continuous reconnaissance and detection around the clock.
They also absolutely cannot discover the existence of the star shelter.
Even Li Chen and others were singing and dancing in the star shelter.
Various ultra-high-power instruments, research equipment, weapons and equipment, etc.
Run at full power.
The enemy is still unable to detect a little bit of energy fluctuations.
This is the power of the most advanced stealth technology mastered by the current star shelter.
But to know one thing.
What one civilization imposes on another civilization.
Regarding the definition of invasion and the safe range of the weapon system set, it is 50 million kilometers.
That is.
Once there is an unauthorized target, it is within 50 million kilometers of a civilization.
That would be tantamount to intrusion.
And it will be directly exposed to the range of all weapons of the opponent's civilization, as well as within the perception range of the energy detection radar.
It will be automatically attacked after being automatically locked by the energy detection radar combined with the fire control radar.
That is to say, those third-level cosmic civilizations are generally recognized as a safe distance.
It is 50 million kilometers.
And the stealth technology of the star shelter.
On the other hand, Li Chen's earth civilization can directly face off, approaching a distance of one million kilometers in front of the enemy.
But it can absolutely guarantee that it will not be discovered by the enemy!
at such a distance.
Attack suddenly.
The enemy will not even have time to react!
This is the current situation, after more than two months of project approval and research and development, and nearly a month of emergency construction.
Star shelter, the most advanced stealth technology mastered!
Since there is a shield, of course there must be a spear.
If we talk about the stealth technology of the star refuge, it can guarantee that they will not be discovered if they are close to any third-level cosmic civilization within one million kilometers.
Then the anti-stealth technology of the star shelter.
It will allow them to discover any invisible targets at a distance of up to 610 million kilometers.
If this distance is specifically calculated according to the celestial bodies between the past solar systems.
It is about four times the distance between the sun and the earth.
Although this distance.
within the bounds of the universe.
Even within the range of a star system.
Nothing.
But you know, this anti-stealth technology.
Can directly lock any target in stealth state.
Whether it is the use of special materials plus fluid physics and other methods.
to achieve invisibility.
It is still stealth in the actual sense, that is, the so-called "absolute stealth".
Combining itself through energy barriers and special material technology.
Perfectly "blended" into the starry background.
Stealth technology that makes the enemy unable to detect its own existence.
The anti-stealth ability of the star shelter can successfully detect the target!
These hundreds of thousands of top scientists in related fields.
Made a significant contribution to the development of the star shelter.
Of course Li Chen had to reward them.
So give each of them a fifth-generation nano clone.
enable them to work more efficiently.
At the same time, when encountering danger, you can also obtain means of life-saving.
This is not excessive at all.
…
At this moment, the highest command center of the star shelter.
Li Chen looked at the wormhole space that flashed past one after another in front of him.
The mood can't help but start to become a little excited.
Also a little bit nervous.
This place is already very close to the border of the sixth star field.
Instead of showing signs of decreasing, the number of star systems is increasing.
The distance between each star system is also becoming denser and denser.
There are even some stellar systems, the shortest distance between each other is less than 1 light-year!
Surrounded by such a huge group of galaxies.
This area is destined to have no life forms.
Because the size of each of the stars here far exceeds that of the sun.
Even the smallest star ever detected.
They are also more than ten thousand times the size of the sun.
Intense light and radiation make this area about 195 light-years long and 107 light-years wide.
Known as the "Dead Zone" because no civilization exists here.
Just go through this dead zone.
They can reach the border area known as the "Great Rift".
There is the border between the sixth star field and the fifth star field.
The reason why it is called the "regional rift".
It's because the border there is really a huge vacuum.
The formation of this vacuum zone is naturally man-made.
Many, many, many years ago, when the tenth sector divided the star domains.
The stellar resources there have been artificially exploited.
All that remains is a dark vacuum band about 2.8 light-years across.
Can't feel it up close.
Because the nearby star system is too dense, the brightness of the light is very high.
But if the distance is extended, it can be observed even from hundreds of light-years away.
You can still clearly see the existence of that dark border line.
The border area is filled with dead silence.
There are even black holes inside.
And pass through this border line bordering the fifth star field.
They can reach the fifth star field.
The temporary outpost supply station set up by the enemy is in an area about 150 light years away from the border between the two sides.
An area called "The Rock Fortress".
That is where the border fortress of the Pulit civilization empire is located.
"Noah, is there any new movement on the enemy side now?"
Li Chen withdrew his gaze from staring at the scene outside the porthole.
Looking back at Noah's projection, he asked.
Getting closer to the border area.
The environment here has become strange and complex.
Around the dense star system, enemy troops may be ambushed at any time.
So one has to be careful.
After all, the enemy can already perceive the unusualness of the earth's civilization.
It is known that the earth civilization is exploiting the resources of the entire sixth star field at an extremely fast speed.
They are not fools, and they can judge the strength of the earth's civilization absolutely immediately.
So it's to be expected.
The enemy will definitely make some corresponding deployments in advance.
But what puzzled Li Chen was the 20-day voyage.
They didn't receive any news at all.
