When critical civilization was born, it had stepped on the limit of the depth of cosmic information.

The word "critical" refers to the possibility that the civilization has to break the boundaries and cross the boundaries of the next generation universe.

The man behind the manipulation of the compound eye is the first critical civilization known to mankind.

Now, after clarifying the concept of critical civilization, scholars have included mankind itself.

Whether it's self anesthesia or it's true, all theoretical calculations are proving this point - mankind must be the most special one in the current cosmic era.

You can find a lot of evidence.

The most important thing is the top secret held by a few core members of the salvation Society - Chen Feng's ability to travel through time and space.

Except that the critical theory can be explained a little, there is no more suitable theory.

Now human beings have realized the real details of the enemy.

This is a war that spans cosmic generations.

The cards of both sides are gradually opening.

The fishstar man is just another temptation.

Next, mankind will inevitably face more means beyond imagination.

Just in the 20 or 30 years since the end of the Voyager star war, there have been dozens of new means on the front line that have never been seen by humans, including special biological arms, strengthened giant guns, and an overlay field energy network that directly shakes the basic physical rules in the region.

Human beings must come up with more means at the same level or higher than the fragmentation bombs, or create super giant fragmentation bombs that can really destroy the universe, return everything to zero, and let the universe enter the next generation in advance, forcing the other party to throw a mouse.

This may at least win a short respite.

But new cognition will still bring new anxiety.

At the moment of the birth of the concept of critical civilization, people can not help but imagine and speculate whether there are really only those behind the scenes from the last cosmic generation in the present universe.

In other regions where humans have not yet arrived, will there still be other critical civilizations from the last cosmic generation or other unknown regions?

No one can be sure.

After all, so far, the time for human beings to enter space is too short. In addition to self discovery in the hunter's arm of the galaxy, the rest of their understanding and knowledge of the universe basically come from fans, compound eyes and a small number of information carriers floating in the hunter's arm, such as Rocky life planets.

The depth of human information has reached the actual energy, but the breadth of information is still limited to the Virgo supercluster, not even the Rania Kea supercluster.

As early as the age of ancient apes, the memory of human population was engraved with a strong vigilance against all unknowns.

Moreover, as Einstein once said, "the more you know, the more you feel ignorant". Human vigilance against the unknown will never disappear with the improvement of the level of knowledge, but will only become stronger and stronger.

This is the case now.

The concept of critical civilization not only expands the imagination and thinking space of scholars and provides a new direction for the next theoretical research, but also causes great fear.

Only blind self-confidence can support the creativity of the whole civilization, continue to forge ahead in the infinite universe and infinite years, and help the whole civilization become the next critical civilization in the real sense.

2713 A.D.

The junction of the gravitational coverage lines of the Han and Vito galaxies.

A small fleet of less than 50000 ships is moving quietly at twice the speed of light.

The fleet has 40000 medium-sized multifunctional main warships.

Each multifunctional main battle ship has a length of 37 kilometers and the whole body is in a geometric pyramid shape.

In addition, there are 5000 large supply ships and 5000 ships of various types, including super small command ships and super large spherical fortress ships.

The shape of these ships is also basically pyramid, and only a few ships are spherical.

A large number of scientific demonstration and practical research have proved that in the curvature flight of 500 times the speed of light, the pyramid shaped curvature bubble with symmetrical front and rear ends is the most stable, and it is the least easy to activate spatial turbulence when it is out of the curvature state.

These pyramid shaped ships are the first 500 times the speed of light cruise ships of CHENFENG empire. Their emergence marks that mankind has officially caught up with the compound eye in the scientific and technological level of manufacturing space flight vehicles.

The model and grade of pyramid ships are uniformly named cosmic type II.

The material of the shell of the cosmos II ship is different from that of the compound eye, which directly carries the underlying structure of the maze core. It is made by human beings using the control force of real energy accuracy and re kneading the triple unified force. It has fairly stable low-energy tearing space, perfect fit with the curvature bubble, ultra-high energy resistance, ultra-high toughness and ultra-fast self repair.

After comprehensive evaluation, the comprehensive performance of the shell material of cosmos II ship is 1.7 times that of compound eye edge ship.

It seems to be only 70% stronger, but in fact it has formed an overwhelming advantage.

In order to create this fleet, scientists and engineers drained the energy of hundreds of stars in a very short time, and consumed a large number of rare resources in special planetary systems that are difficult to regenerate.

The so-called difficult regeneration means that the cost of artificial synthesis is too high and takes too long.

It's not impossible to synthesize a little from the perspective of real energy level, but it will waste a lot of valuable time.

At present, more than 95% of the universe II ships made by humans are all in this nameless fleet.

The General Commander of the fleet is Qin Guang, who emerged in the battle of traveler galaxy.

At Qin Guang's current rank, he did not dispatch troops on the main battle front, but led such a small fleet to move quietly. Of course, it can only be because the task to be performed by this fleet is extremely important.

This is the first time in the long history of human resistance to send an expedition fleet to the silver heart, ready to go straight into the heart of the compound eye in the galaxy.

The unknown fleet has many tasks, such as destroying the long-range command center of the compound eye, uprooting the habitat established by the compound eye in the Milky way, and liberating and attracting as many slave families enslaved by the compound eye for millions of years as possible.

If you can, you should also obtain as many communication records as possible between the compound eye in the Milky Way galaxy and the compound eye in the Virgo local Galaxy Group, so as to analyze the scientific and technological development route, military strength, social system and other information of each other's parent star.

At the same time, humans also want to intercept each other's intelligence and see more information about the Virgo supercluster and larger space units.

Risks and opportunities coexist forever. Compound eyed people are not only the sword of extermination hanging over the head of human civilization, but also may become a stepping stone for human beings to step into the universe.

If nothing happens, the unknown fleet will quietly cross the front line with the help of the latest camouflage technology, avoid the travel route of the follow-up army of the compound eye, enter the second level supercurve flight from another channel, reach 500 times the speed of light, and finally reach Yinxin in about 2980.

The shortest sailing time of the fleet is 267 years.

Today, the human body freezing technology is still not perfect and can not stop the disintegration of human brain thinking. 120 million soldiers, 20 million scientific researchers and 30 million engineers in the fleet never considered returning to their hometown when they set out.

Even most people here are unlikely to live to reach their destination.

But what does it matter?

Human beings have been used to this way of continuing to advance in the universe through the reproduction and survival of generations.

Even if the folding star gate can infinitely accelerate the pace of human progress, there must be the first batch of people who eat crabs at the forefront of everyone, and they will always be on the way forward?

Otherwise, who will collect information, complete accurate parameter capture, and finally establish the Stargate step by step?

Wearing a major general's uniform, Tong Ling, an adult, stood in the communication room of the loading ship of one of the small special operations units of the unknown fleet.

She looked at the telematics with a smile.

The projection shows her parents far away in Ceres.

Her parents now live in the ahuna mountain villas on Ceres.

A family of three has not seen each other for 28 years.

Tong Ling is now a valiant young soldier, but the crow's feet can be seen in the corners of her parents' eyes.

It seems that the short twenty-eight years have made them a lot older.

They are indeed over 110 years old.

The second old man seems to be standing on the balcony of the villa. From behind the second old man, you can see the distant new sun.

The new sun is far away from Ceres. It looks only the size of sesame and mung bean, and the light is also very dim. After filtering the anti radiation energy field, the new sun looks like a red bean floating in the air.

But Tong Ling can't help but pinch her fists. This is the sun of her hometown.

She smiled and said, "Mom and Dad, I'm going to perform a long-term task and may go far away. For confidentiality, this is also our last quantum communication. In the future, you two should take care of your health. Dad should go to bed on time and mom, don't work too hard."
