Homo sapiens.

Of course, some people are willing to retain the physical characteristics of men and women, mainly for the purpose of expressing individuality.

For the new humans at this time, social forms such as gender and offspring have already undergone significant changes from the Earth era.

Celtic is a typical neutral person, he asked: "Li Fan, what's the matter?"

"This is an order from the board of directors." Li Fan, the purple-haired man, shared a document with him.

Celtic browsed right away.

After a while, Celtic nodded: "I understand, reply to the board of directors for me, and I will complete the preparations within three days."

"Ok."

After Li Fan drifted away.

Celtic immediately summoned a dozen subordinates.

They are in the control center of the star's gravitational system at this time.

After reading that document, an officer frowned: "Minister, time is too tight, there is no way to clear the direction of attack!"

But Celtic's eyes were cold: "There is no time. The other party has discovered our civilization fire, and we cannot let them destroy our nano-robots. We must use high-frequency resonant gravitational waves to strike and support the nano-robots."

"But……"

Celtic clenched his fists tightly: "There is nothing but two planets! It just so happens that the surface resources of this planetary system are almost mined, so just blow up those two planets."

Hearing Celtic's decision, everyone knew that it was not the time to care about the two planets, so they immediately replied in unison:

"Yes! Guaranteed to complete the task!"

Soon the inside of the control center of the stellar gravitational shield system began to get busy.

And the two planets that happened to be hit by this blow, the new humans, spaceships, and space battleships on them were also evacuated within two days.

Day three.

With Celtic's order.

In an instant, the radiant energy of this red dwarf star was quickly drawn, and then injected into a pseudo-gravitational field generator.

"emission!"

After adjusting the orientation and gravitational wave frequency.

A terrifying quasi-gravitational wave erupted from the void on one side of the red dwarf star, and swept towards another planetary system 6.7 light-years away at the speed of light.

The 5th and 8th planets of this planetary system are just within the strike range of pseudo-gravitational waves.

When the undulating quasi-gravitational wave swept over the two planets, the two planets soon began to show signs of disintegration.

After 14 days, one of the terrestrial planets had completely disintegrated, leaving a pile of planetary debris and nebula particles.

After 33 days, another gaseous planet couldn't hold it anymore, and disintegrated into hundreds of debris and a large number of nebula particles.

And the other side.

The planetary system 6.7 light-years away.

The silicon people who discovered the invasion of human nano-robots are now trying their best to encircle and suppress the human nano-robots scattered throughout the planetary system.

However, the result of the confrontation between the two sides shocked the leader of the silicon family in this planetary system.

[Why are these nanorobots immune to electromagnetic waves? 】

More than a dozen silicon engineers in charge of scientific research are also doing their best research at this time.

It's not that the silicon family has never encountered a first-level civilization with nano-robot technology before, but this is the first time they have encountered nano-robots that are not subject to electromagnetic interference.

It was precisely because they did not expect that, when they first responded, there were obvious loopholes.

Not only did they fail to destroy the nanorobots, but they took the opportunity to control an earth-like planet and two large natural satellites.

One of the silicon engineers guessed cautiously: [Leader Jaguli, I suspect that the enemy may have long-distance delay-free communication technology]

[Long-distance delay-free communication? ] Jaguli, the leader of the silicon family, blinked his electronic eyes, as if he was thinking about this possibility.

Other silicon engineers also spoke one after another. Obviously, after studying a series of data, they all tend to have long-distance delay-free communication technology for human civilization.

Jaguli, the leader of the Silicon Clan, actually believed in this speculation in the calculation and operation unit at this time.

After all, it is impossible for a nanorobot itself to have too strong computing power and information storage unit.

Without long-distance, delay-free communication, the opponent's nanobots could not be so flexible.

What makes Jaguli even more disturbing is the energy supply method of these nano-robots, and how they appear in the planetary system of the silicon family.

These two situations made Jaguli feel that the enemy was unfathomable.

It quickly ordered its subordinates: [You immediately report this incident to other tribes, and let them pay attention to check the interior to avoid being infiltrated by the enemy's nano-robots. 】

【Obey, leader Jaguli! 】

Then Jaguli wrote a speculative report and asked the communication department to launch it together.

After completing these arrangements, Jaguli also became ruthless, and at the same time, his inner ambition instantly swelled.

It began to mobilize all its forces, trying to capture some nano-robots, and then crack the communication technology and energy supply technology of human nano-robots.

Unfortunately, human civilization has long thought of this.

Don't give the other party any chance at all.

The two sides launched a crazy fight in this planetary system.

In front of the crazy silicon people, the nano-robots without the advantage of sneak attack began to retreat steadily under the attack of the opponent's nuclear bombs and plasma cannons because they did not have enough time to develop.

However, the human administrators who control the nanorobots are not vegetarians.

Since you can't do it head-on, let's play guerrilla.

Even if they are as strong as the silicon family, in the face of the starry space guerrilla warfare of nano-robots, they have no way to quickly eliminate all the nano-robots hidden in this planetary system.

In the blink of an eye, 6.7 years have passed.

this day.

The people of the silicon race who have driven the human nano-robots out of the inner circle of the planetary system suddenly felt their bodies floating in one direction.

High-frequency resonance gravitational wave strike arrives!

The entire planetary system was suddenly pulled violently for several ten minutes, and then the gravitational force disappeared without a trace.

However, this is just the beginning.

For the next 100 days, the planetary system was gravitationally swept up in unprecedented chaos.

And those human nano-robots also began to revive, and with the help of the window of the silicon family that was hit hard by the chaotic gravitational waves, they began to crazily expand and occupy the planet.

The offensive and defensive momentum was reversed instantly.

Chapter 7 Ten Deadly Distance

Galaxy for 23325 years.

More than 1000 years have passed since the strike of human civilization reached the Andromeda cantilever.

And the Andromeda silicon family not only failed to counterattack human civilization, but fell into continuous wars.

In the joint command center of the humans in the Andromeda constellation, the officers of various groups who communicated synchronously looked at the huge holographic projection star map.

This star map is exactly the distribution map of the forces of the Xianying Constellation Cantilever at this time.

Although the Andromeda cantilever is the old nest of the silicon family, it is still gnawed down by human civilization.

Judging from the power distribution on the star map.

The side of Andromeda's cantilever close to Orion's cantilever seems to have been eaten by worms with 11 big holes.

Each hole is like a huge bowl, with a radius of about 600-700 light-years.

Three of the occupied areas have now been connected together to form a whole.

At this time, the silicon tribes of the Andromeda Silicon tribe who are close to the front line finally know that human civilization is invading the Andromeda cantilever, but it is a pity that they know it too late.

Now that the humans in Andromeda have gained a firm foothold there, once the planetary system of the Silicon Race is occupied by human civilization, it is almost impossible to regain it again.

The more serious problem is because of the communication technology of the Silicon family, the speed of light communication is too slow inside the star system, and the communication delay of hundreds or thousands of light years makes a lot of information lose its timeliness.

Now, only some of the tribes near the front line of the Silicon Clan in Andromeda know that the enemy is invading, while other tribes that are farther away only know that they have been attacked by an unknown enemy.

Even a part of the tribes of the silicon race in the outer area of ​​the cantilever of Andromeda has not been hit by the neutron shells of human beings.

This is the huge limitation of light-speed communication in the era of stellar systems.

Human civilization is undoubtedly fortunate.

Just entering the stage of first-level civilization, synchronous communication technology was developed by mistake. This communication technology allows human civilization to avoid many dangers and obtain long-distance real-time information.

Even if they are as strong as the silicon civilization, they have no way to avoid communication delays, which is the fundamental reason why the silicon civilization has developed into isolated tribes.

Even if human civilization separates a large number of subsidiaries, these subsidiaries are still not completely independent.

Synchronous communication has guaranteed the unity of human civilization to a certain extent, especially the technology and cultural exchange conference held every 10 years, which has made the technological development speed of human civilization not decline as fast as other first-level civilizations.

This is another problem discovered by human civilization after a series of observations and researches.

In the process of civilization development, it is actually very difficult to maintain the speed of internal technological development.

There are a lot of "forked roads" and "traps" hidden in it. Without other civilizations to refer to, it is as difficult as eternal life to maintain the rapid development of science and technology.

From the perspective of think tank scholars of human civilization, there are many factors that restrict the development of a civilization's science and technology.

These include: the way race is learned, cultural habits, individual identities, patterns of social functioning, and more recently, the speed of transportation and communication.

Compared with human civilization in other respects, silicon civilization is actually similar.

Even if they are information creatures, they have already realized that the superorganism mode is a dead end, and abandoned the superorganism mode very early, forming independent individuals with various personalities.

However, the scientific and technological development speed of the silicon civilization is not much faster than that of the omnic civilization. The silicon civilization that has developed for 766 million earth years is still inferior to human civilization. What is the problem?

In the final analysis, it is the limitation of communication and transportation.

This is also the reason why human civilization separated a large number of subsidiaries.

Under the limitation of traffic, the maximum utilization radius of resources of a first-level civilization that cannot travel faster than light will not exceed 10 light-years.

In this case, without setting up subsidiaries or separating semi-independent tribes, there is no way for a first-level civilization to manage colonies more than 10 light-years away.

Even management is difficult, let alone utilizing the colony's minerals and energy, as well as the colony's talents.

After all, as the distance increases, the time interval for communication between the two parties becomes longer and longer.

Take the situation of the silicon civilization in the Andromeda cantilever as an example. Their tribes on the inner and outer layers of the cantilever reach a distance of about 1.7 light-years.

Even at the speed of light, it takes 3.4 years to go back and forth.

Moreover, light-speed communication is difficult to maintain information density over long distances.

The information technology of the silicon civilization is definitely unique, but it can only guarantee the integrity of high-density communication within 5000 light-years.

It takes a long time for a communication.

Even if the various tribes of the Silicon family are united, there is no way to achieve talent sharing and rapid technical exchange.

This limitation has further led to the fact that each tribe can only fight alone in terms of scientific research, and there is no way to work together.

Human civilization uses synchronous communication technology to allow each subsidiary to focus on only a few scientific research fields, and other fields to be completed by brother companies. At that time, everyone will communicate at the exchange conference and quickly make up for other shortcomings.

In this way, talents and technology within human civilization can join forces.

However, the various tribes of the silicon civilization are limited by communication technology, so there is definitely no way to compete with human civilization in scientific research speed.

Regardless of the current territory of human civilization, it is still less than 30% of the silicon civilization, but in fact, the total strength that the two sides can use in the warring area, human civilization is at least [-] times that of the silicon civilization.

The difference between communication technology and transportation technology has led to a reversal of the advantages of the two in local areas and within a specific period of time.

This is like, silicon civilization has [-] soldiers, but human civilization has only [-] soldiers.

The two sides are at war, and the human side is all heavy armored cavalry equipped with walkie-talkies and binoculars; the silicon clan is all infantry, and communication depends entirely on roaring.

When the war broke out, the Silicon tribe was still stationed in various small towns. Even if all the human cavalry did not attack, there were hundreds of cavalry fighting dozens of infantry during local battles.

In this case, how did the silicon family arrive?

This is simply an unsolvable deadlock.
