Half-immortal civilization

At the end of the 61st year of the imperial calendar, the vast square of the prosperous imperial capital was crowded with people, and a tall flying saucer was ready in the distance.There are so many flying saucers that they can't be put down on the ground; but it doesn't matter, the advanced anti-gravity technology is enough to make the flying saucers stay in the air quietly and wait in line.

Passionate music filled the surroundings. Among the boundless crowd, there was a group of straight people wearing standard uniforms different from the imperial military uniforms, with the words "Yanhuang Empire" on their chests.They are heroes who are about to leave Venus!The Yanhuang Empire is a branch of human civilization that is about to rise in the whale constellation, and now, with the permission of the empire, they have established a country on Venus.

And today, in this square, a major event that will affect human interstellar civilization will happen!The newly established Yanhuang Empire, which has no territory of its own, will hold its first international exchange.

At nine o'clock, when the sun just appeared, a mighty group of people drove into the square. In the noisy square, people automatically made way for these people to come to the center.

The huge three-dimensional projection technology sends their heroic appearance to a thousand meters high, so that everyone in the square can see clearly!
Since the establishment of the empire, from the first generation of leaders to the current leaders, as long as they can attend, all of them have appeared, even great scientists and so on.Thousands of people are mighty.

Also present at this meeting were representatives from the Earth Republic.This is not only a grand event for Venus, but also a grand event for the Chinese nation and the civilization of the entire solar system!
Stepping... Zhang Jingyuan stepped onto the rostrum; the years did not leave any traces on him.

Long live... Long live... Zhang Jingyuan has not yet spoken, but all the citizens have already started to cheer.

"People of the empire, hello. I am very happy to see that you are full of energy." Zhang Jingyuan spoke softly, and the people boiled again.For the great emperor who built the empire single-handedly, this great man who single-handedly promoted the great progress of human civilization is almost a myth now.In addition, such a grand event is beyond Zhang Wenliang's control; among other things, only Zhang Jingyuan has that qualification and status.Announced that Li Changxing and others established their own empire.

Amidst the cheers, Zhang Jingyuan directly discarded the microphone, and the mighty voice slowly unfolded.Covering every corner of this city with a population of nearly 5000 million, "Throughout the history of mankind, human beings have appeared since millions of years can be examined; since ten thousand years, the process of human beings entering civilized society; Human beings have entered the era of technological development.

But I want to say, no matter what, human civilization will once again enter a new era today!From this moment on, human beings truly have the right to control their own destiny!From this moment on, we will begin to move towards the path of total domination of our own destiny!planet.Our steps cannot be bound, and the solar system cannot bound our minds.Our tomorrow lies in this vast universe.

And today, we will witness the newest page in the history of human civilization!The establishment of an empire outside the solar system.This empire is the Yanhuang Empire.From this moment on, we have officially entered the threshold of interstellar civilization!
(pointing to the 2000 million people who are ready) They are the 2000 million warriors who are about to leave Venus and the solar system.They will use their bravery and life to open up a new era.

We pay tribute to these warriors.Mankind can exist today because there are countless heroes who have gone on to succeed; and now, we are honored to have 2000 million pioneer heroes, who will expand a new survival base for the entire human race.

This is a turning point in history, a turning point in civilization.today.Here, let us pay high tribute to these heroes, and let us wish them all the best and success.Now, the grand ceremony begins.

First, let us celebrate the founding of the Yanhuang Empire together.They will be the third unified country of human civilization.They will continue human civilization and the spirit of China 12 light years away! "

"Long live..." people cheered.Although I already knew it, but I still can't help myself when I wait for it!

The passionate national anthem wafts.One nation, one song!The March of the Volunteers will surely fly over the sky of the third country.Maybe.In the future, all human interstellar countries will adopt the same song!This will be the bond of the human spirit!

Countless people at the scene sang quietly and watched the three national flags rise slowly.The new national flags of the Republic, the Chinese Empire, and the Yanhuang Empire... The new national flag is a phoenix reborn from the ashes!Heralds the birth of mankind.

The singing continued for a long time, over and over again, Li Changxing walked slowly onto the rostrum, "Hello everyone, my name is Li Changxing. Of course, I think many people know it. What I want to say is that the royal family of the Yanhuang Empire will have me and Represented by the Li family.

Similarly, here, I promise that the Yanhuang Empire is still the empire of the Chinese people, and it is also the country of civilization of the Chinese people.On the basis of retaining all the systems of the empire today, changes in line with public opinion will be made. "

"Wow..." Although the applause was not as enthusiastic as Zhang Jingyuan's, these promises still made people feel good.People who live in the empire certainly understand how open the empire is. Not to mention anything else, just saying that they carry guns with them is enough to make everyone grateful.Especially in these years, the laws of the empire are just and strict, and the politics are clear and clear, which has made the cause of the empire flourish and made people completely sure of the existing centralized system.

"Continue to the second item." Zhang Jingyuan walked slowly onto the rostrum again, "The Republic and the Huaxia Empire jointly presented the Yanhuang Empire with a gift! A memory card with the March of the Volunteers inside.

Same nation, same song.No matter the ends of the earth, no matter what system, no matter what kind of national flag, national emblem and national policy we have, we will all have the same song!

He is: March of the Volunteers! "

Li Changxing quietly took the memory card packaged in an ordinary box, and held it high above his head.

Hush, huh, huh... the same nation and the same song, the atmosphere on the scene reached its peak at this moment.Similarly, people far away on the earth can also watch the live broadcast—the live broadcast relayed by the superstring communication technology.

"Finally, let us congratulate the heroes and wish them a smooth arrival at their destination and the successful establishment of the first human settlement outside the solar system!"

The passionate national anthem is the best accompaniment.All the people sang a song together, and a kind of pride was completely detonated.

With neat steps, 2000 million people began to board the plane one by one.Go to space.The flying saucer in the sky is like a long dragon and a ladder to the sky, sending the heroes into space one by one.

Everyone looked up at the sky, and under the scorching sun, a spot of light the size of a fist shone brightly in space. It was the Civilization spacecraft that was ready.Large and small flying saucers rose and landed; the passionate national anthem resounded through every corner of the empire.

Look at the busy scene in space.People sing solemnly.Passionate, blessed, and yearning.

With 2000 million people on board, even if the empire activated almost all flying saucers that could be confiscated, it still took a day to send everyone into space.

Li Changxing and others left at the last moment, under the attention and blessings of the world.In any case, the first interstellar migration of human beings has already started.People are full of hope for the future.Perhaps, that planet already has its own intelligent race, but at this moment.No one thought of saying something for those intelligent races!have been selectively ignored.

Although the battle of civilization has not yet begun, everyone seems to know the process.There is only one place to live, so this is destined to be a fierce battle!Until one party disappears completely!
In space, Zhang Chengye held the battle in person.Leading the technological team of the empire, quietly waiting for the moment of departure.The entire 150-kilometer-long Space Research Institute now concentrates almost all functions to serve the Civilization spacecraft!Today, it is the heart of the empire in space.

"Tick tock..." In the [-]-square-meter control room, apart from hundreds of central computers tracking various detectors, there are tens of thousands of central computers.All hit forces monitor and contact all dynamics of the spacecraft.Even, it is expected that they will pass by as much as possible near the location with superstring communication devices along the way, so as to grasp everything about the spacecraft in time.Of course, the spacecraft itself must carry a superstring communication device, but humans still need another way to monitor the spacecraft-because of it.It's so important!We do not allow the slightest deviation!

Standing here at the Space Research Institute, it is enough to see the huge spaceship in the distance.The flying saucer, which is thousands of meters in size, shuttles back and forth on it like ants, transporting people.

At the same time, the entire human society is also paying attention to this migration.Not looking for new continents, but looking for new new planets and new stars.Pride is difficult to express in words.Everyone looked up to the sky.There is an inexplicable impulse in my heart.

Now, every 10 minutes, Zhang Chengye needs to contact Li Zhengying, the chief controller of the spaceship.

"Zhengying Zhengying, I'm Zhang Chengye. We still have three hours to take off. Is there any problem with you?"

"Checking!" Li Zhengying replied simply and simply.In fact, it is indeed being checked!It's just that I don't know how many times this inspection has been done.In addition to checking with different software, manual checking is also required.In the ten years since the construction of the spacecraft was completed, the spacecraft has been inspected countless times, and it should be perfect in theory.However, such a huge spacecraft is under great stress and must be checked at all times.And the technical team on the spacecraft led by Li Zhengying needs to monitor the spacecraft at all times.

While people were cheering, the scientists of the empire were in the most tense state.To be exact, this is the battlefield of scientists in the peaceful age!

The countdown ticked away, and people looked up at the sky, even if they couldn't see it, they silently blessed in their hearts.

Some people shed tears because they have family members and relatives, and they are in this immigrant team.There are also some people who really feel the tenacious power of human civilization and the spirit of never yielding and always moving forward!

In the huge square, people are quiet, and the stereoscopic projection technology allows people to observe everything on the ground.

"On August 61, 8 Imperial Calendar, at 10:15 noon, the spaceship will start to ignite, and mankind will enter a new era!" Zhang Chengye closed his notebook.

In the distant space, with the end of the countdown, the huge spacecraft has begun to launch.It seems that the ancient giant is waking up!The smooth surface suddenly wrinkled, and then a huge solar sail slowly stretched out.Today, the solar sail is still one of the most ideal acceleration devices in the human universe technology system.

However, the solar sail of the Civilization spacecraft is a bit scary!With a diameter of more than 500 kilometers, it spreads out in space, like a continent!The area is 20 square kilometers!

And to propel this monster's spaceship.The empire even built two mirrors of more than [-] million square kilometers to focus the light from the sun and transmit it to the huge base of the Academy of Space Sciences.Then superimpose through dense arrays one by one, and then emit these rays of light into space.Push the spaceship forward!
Now, the powerful light force is pushing the spaceship to start moving.But in order to get rid of the gravitational force of Venus and the sun, the spacecraft itself needs to be stronger.

The whole body of the spaceship adopts the most mature and advanced propulsion technology in the empire: Gentian Engine No. 1, with a single thrust of up to 1 tons.Different from the previous single-shaft engine, Gentian 100 is a combination engine, which is composed of multiple power chambers, and the energy conversion efficiency is close to [-]%, which is the top technology and process in the world today.

but.Such an engine needs to consume up to hundreds of tons of pure water per hour; for these working media, the Empire extracts water from the permafrost layers of Mercury and the Moon—the water on Venus itself cannot be wasted like this.You must know that the water in the space will be distributed to every corner of the universe, which is a kind of wasteful behavior.used up.It will never be taken back!
In addition, in the past ten years, the empire has used light decomposition technology to decompose water into hydrogen and oxygen, and then compress and store it to store energy.And now, that hydrogen and oxygen are in the Gentian 1 engine.It burns violently, and is then catalyzed into plasma by huge electric power, driving the engine blades to work with a high temperature of tens of thousands of degrees.

In order to send this monster out of the solar system, the empire has really been preparing for ten years without interruption.Energy is one of the most important considerations.Nuclear energy is good.But the explosive power is lacking!Traditional fixed energies, such as fossil fuels, have good explosive capabilities, and as much as is needed can be ignited immediately-as long as the quantity is sufficient.Its flexibility is something that nuclear power cannot achieve anyway.certainly.If the cost is not considered, nuclear power is still possible, but considering the cost, it has no practical value.

In space, the empire uses light to decompose water to store energy. Now, these compressed liquid hydrogen and oxygen are the best propellants.For these, the empire has been stockpiling for 20 years.And such an excellent energy storage method will also be one of the ideal ways for the empire to store energy in the future.Water is still relatively abundant in the universe.

It is very difficult to start a spacecraft weighing hundreds of millions of tons.Just the gravitational force between it and Venus is very huge.If a small object can move under a slight force in space; then this huge object will not see any change even if it is pushed by water for tens of thousands of years.

Therefore, in order to start, not only the engines of the spaceship itself are all turned on, but even the solar sails are fully opened.

The silent space, the light blue engine tail flames make the spacecraft seem to become a city wall dotted with blue flowers, a new Great Wall that escorts humans to space, but this city wall moves extremely slowly.The huge mass makes the anti-gravity magnetic engine useless here, and only the top plasma engine can do it today.

Gradually, faint water vapor began to permeate thousands of kilometers of space, like a dream under the sun.

There is also a golden pillar of light—like a celestial pillar, connected between the spacecraft and the Institute of Space Science/Base.Such a huge light thrust can reach one billion tons of thrust!Of course, the Academy of Space Science, which is the turning point of light, also has to bear the reaction force of one billion tons, and has to start all the engines to adjust the balance.As for the large mirrors that reflect light in space, the force received is very small, and the built-in motor is sufficient to complete the adjustment.

Inch, inch... The bulky spaceship is so reluctant to leave its hometown.Although all the thrust has reached its peak, its acceleration is still slow.Citizens of the empire who are accustomed to high speeds find it difficult to accept this kind of acceleration of only one meter per second.

You know, when the cosmic probe was launched back then, it was launched by a star cannon, which accelerated to 0.4 the speed of light in 0.15 seconds!Converted down, its acceleration is as high as 14.25 kilometers per second!
In addition, the technological progress of the empire over the years has allowed the trains on the ground to easily reach a safe acceleration state of 20 meters per second-in fact, it is said that the limit state will be even higher and higher.

In the report, the top space shuttle can even reach an acceleration of more than 800 meters per second!Also, it is said that the momentary acceleration during the attack of the mecha.Possibly up to 1200 meters per second!
In comparison, the acceleration of the current spacecraft is really unbearably slow.But—this spaceship is too heavy! 2000 million people!Sealed up all the engineering equipment needed for an industrial system!Basic living material requirements - In the 30-year living environment of Space II, there is always a need to produce some basic living materials!Not to mention that there are hundreds of millions of tons of water, massive amounts of compressed air, tens of thousands of fighter jets, internal rail traffic shuttling every corner, and the spaceship itself is a metal monster!

Massive amounts of water vapor spread in space... a space with a diameter of one thousand kilometers, two thousand kilometers... ten thousand, one hundred thousand kilometers...

gradually.The thin and hazy water vapor actually enveloped the entire Venus...

With a medium, sound can travel...

From the civilization spacecraft, the huge roar of all the engines spread through the thin water vapor!It has been transmitted to man-made objects in space, to space science bases, and even to the ground of Venus.

The sky is really trembling!

The multi-billion-ton thrust engine was working at full power and unscrupulously. The blades stirred the plasma, and after the panting plasma cooled down, it was a violent eruption of water vapor.Trembling so violently, a terrifying sound erupted, even if the water vapor in space was thin, there would be a roar.

That roar was more like the roar of heaven and earth.It was as if the sky was being torn apart.

But even if the acceleration is only one meter per second, after 30 hours of uninterrupted acceleration, its speed has reached a terrifying speed of 108 kilometers per second.Space, the space is too big, as long as there is a basic acceleration, and the acceleration continues, theoretically any object can reach 99% of the speed of light - infinitely close to the speed of light.

30 hours down.The spacecraft has advanced a distance of more than 580 million kilometers.Perhaps, this distance looks very small in the universe, but from the perspective of human beings—this spaceship with the hope of all mankind has begun to take its own steps towards the unknown space.

Today's space is beautiful...and spectacular!
The water vapor emitted by the engine also extends for nearly 600 million kilometers.Although thin, it is enough to carry the sound.For 30 hours a day, Venus is enveloped in the ripping sound of the sky.In space, this water vapor range is more like a pyramid, a celestial pillar!
At the position of Venus, the water vapor has spread to a radius of 50 kilometers.The spaceship in front is still tirelessly releasing its power, and a large amount of water vapor is still violently erupting.So much water vapor inevitably blocks part of the sunlight, and even reduces the efficiency of the solar sail to [-]%; half of the light is thus intercepted by water vapor.

Seen from the sky, in the center of the water vapor pyramid with a diameter of 580 kilometers at the bottom and hundreds of kilometers at the top, is a golden beam of light [-] million kilometers long!It is the sunlight after polymerization!
In fact, there is no good way for the empire to do this.In the beginning of the spacecraft, whether it was the engine itself or the light itself, the thrust alone was insufficient.The gravitational force from Venus and the sun makes the spacecraft unable to break free; only two-pronged approach will be effective; in one day, it has reached a speed of 108 kilometers per second, and as it escapes from the gravitational circle of Venus, the acceleration is getting faster and faster. come faster.

Suddenly, the voice from space disappeared.After searching, people found that the spacecraft had already shut down all its engines, and now it only relies on the solar sail to move forward.Engines use a lot of water - and water is precious.During the entire progress of the spacecraft, there is no way to replenish any resources at all.After leaving the solar system, you will enter the vast and almost empty space until: reaching the constellation of Cetus!

For nearly 30 years, people could only live on the supplies of the spacecraft itself.The environment in space will not be too luxurious—it may even be struggling on the line of food and clothing.
