Chen Yue plans to produce a fixed type of spy detection satellite.

In his plans, the spy satellite was about the shape of a round ball, only ten centimeters in diameter, about the size of a large apple, with four antennas extending from it like toothpicks.

This kind of gadget only has a mass of about 10 kilograms. Moreover, this kind of spy detection satellite has a simple structure and a single function, even if the second-level civilization has a scientific and technological level, it can be manufactured, and at this moment human civilization has really become a third-level civilization, and there is no difficulty in manufacturing this thing.

In particular, Chen Yue has done his best to optimize the structure of this spy detection satellite and sort out the manufacturing process with the technology of the three-level civilization, so that its manufacturing difficulty has been greatly reduced, and the demand for special materials is very little, almost nothing. It can be produced by relying only on some common elements and compounds, and the production cost and difficulty of production are reduced to the point that there is no lower level.

In addition, all of Chen Yue's construction tasks in the Weia galaxy are mainly based on the construction of this simple spy detection satellite, except for some necessary repairs, basically no computing power and resources are wasted in other aspects.

Under such circumstances, it is foreseeable how terrifying Chen Yue's production capacity will be with this kind of spy detection satellite.

But...... Faced with the production tasks in the future planning, Chen Yue was still a little excited.

Although this kind of spy detection satellite is simple to manufacture, simple in structure, and low in cost, all these advantages are completely offset by one factor.

Quantity.

That's right, quantity!

What Chen Yue wants to build is not 10,000,000, not 100,000,000, not 100,000,000,000,0......00,000,000,000,000,000,000,000,000,000,000,000,000,000 Ten billion billion!

The mass of a single such satellite is 10 kilograms, or 0.01 tons. The total mass of 10 billion of these satellites is 100 million tons!

You must know that before the earth was destroyed, the mass of the entire earth's atmosphere was only 5.15 trillion tons.

These gases are the source of all the wind, rain, thunder and lightning on Earth. They envelop the entire earth like a thick cover, creating a thousand magnificent sights and incredible weather phenomena.

And the mass of all the gases that make up the Earth's atmosphere adds up to just over half of that mass.

This is an unimaginably huge project for any third-level civilization, or even a fourth-level civilization. In the face of this level of production demand, even a fourth-level civilization is unsustainable.

But Chen Yue embarked on this task without hesitation. And, he has absolute confidence that it will be done.

Chen Yue had to complete this unimaginably large construction task. Because Chen Yue planned to do something unprecedented that no level of civilization would dare to think about, or even think about at all.

Chen Yue tried to cut off the communication link of the entire Wang Liang Samsung system to the outside world!

Only by cutting off the external communication link of Wang Liang's Samsung system can Chen Yue carry out follow-up plans, and can he smoothly "join" the Star Alliance system, and complete his own development with the help of Star Alliance protection.

The actual environment requires Chen Yue to do this in order to grasp the initiative of the right to survive in the future to a certain extent.

However, it is very difficult to cut off the communication link of an entire galaxy to the outside world. Even ordinary civilizations don't even think about it. For any sane person would have known with a simple calculation that such a thing would not have been possible.

Civilizations of Level 3 or above generally use over-distance communication technology as a means of communication. The Southern Star Civilization and the Blue Moon Civilization are of course no exception.

Chen Yue's over-distance communication distance, along with the development of mathematical sciences during this voyage, extended to a distance of about 180 billion kilometers, about 0.019 light years. The communication length of the Southern Star civilization is 0.1 light-years.

Beyond this distance, it is necessary to build a communication relay station to transmit the information piece by piece, so that it can be transmitted to a place far beyond the upper limit of the communication distance.

It's like the Southern Star civilization. The Southern Star System is about 27 light-years away from the Wangliang Samsung System. Theoretically, as long as 270 communication relay stations are laid in this distance, the front-line headquarters located in Wang Liang's three-star system can maintain real-time communication with the civilization headquarters of the Southern Star System.

Of course, this is only theoretical. In reality, the number of communication brokers will never be so small. It can be a thousandfold, ten thousand times that. These communication relay stations will be located in different places according to different communication needs and interstellar environments, make different camouflages, and use each other as backups to ensure the security and stability of the entire communication link.

Communication is an extremely important part of interstellar warfare. To some extent, cutting off communications from the front and the rear is tantamount to winning the war.

So, in an interstellar war, why don't the warring parties try to cut off each other's communication links to win the war?

If you don't do such a huge benefit, there can only be a single reason, and you can't do it.

Yes, the real reason is that it can't be done.

The reason is simple, the universe is too empty and too vast. The opposing side simply cannot search every interstellar space, and find the enemy's communication relay stations that exist in this space.

For example, at this moment, the super-distance communication technology of the Southern Star Civilization and the Blue Moon Civilization is almost the same, both of which are 0.1 light-years away. Then, if you want to completely cut off the communication link between the opposing civilization and the rear, you need to find and destroy all the enemy's communication relay stations within a radius of at least 0.1 light years.

It has to be all of them, and none of them can be left. Because, even if you destroy 10,000 and only one remains, this one communication relay station can still perform the communication relay mission, and the whole operation is meaningless.

Because the communication distance limit between the Southern Star Civilization and the Blue Moon Civilization is 0.1 light-years away. And all the communication relay stations within this 0.1 light-year range have been destroyed, so it is obvious that this communication link has been cut off.

No amount of transit points in the rest of the place is of any use.

It's like a 10,000-kilometer railway that has only been interrupted by one meter. A one-metre interruption is enough to make the entire railway unimpeded.

So, how difficult is it to search for and destroy all the communication brokers within this 0.1 light-year range?

The realistic answer is that it's too hard to do. It's so difficult that ordinary third-level civilizations, or even higher-level civilizations, don't think about this at all, and they don't even think about it.

If someone proposes to aim at this and try to do it, whoever it is, will think that he is a madman.

But now, Chen Yue intends to do this.
