Rebirth of a technological power

Shennong star.

This is the name given by China to the outermost planet of life in the Proxima galaxy. Shennong belongs to the "Three Emperors" in Chinese myths and legends. He is the leader who led the rise of the Chinese nation and also represents hope.

The spacecraft landed, the hatch opened, and astronauts, scientists, and engineers in mechas walked out of the hatch, and engineering vehicles and robots drove out of the cargo warehouse.

They began to build communication base stations here. This was not an ordinary communication base station, but a large communication base station that could span star systems.

In addition to large communication base stations, they also need to build controllable nuclear fusion power stations to provide electricity for the entire base.

In two years, they will build a human base here and a space shuttle here to carry out travel between two living planets and develop resources.

Except that some of them will get married and have children here and work at human bases. They will not set off back to Earth two years later.

At the same time, scientists will study the two lives and establish a detailed database to provide scientific data for the future.

Such as the proportion of various gases in the air, temperature changes and other data.

For example, the types of creatures that exist, their characteristics, etc.

Even microorganisms such as bacteria will not be spared.

Two years may seem like a long time, but for this first group of people, it is very short.

The short time is so short that everyone has to work every day, and there is no such thing as a holiday.

The engineering vehicles and robots brought from the earth are only for initial use, and more engineering vehicles and robots will need to be built later.

Various types of robots are available in the technology library. You just need to follow the instructions in the technology library.

As the commander, Liu Yang is also the highest officer among the three hundred people. She also participated in the construction. Of course, as the commander, her responsibility is to coordinate and arrange the work of everyone.

In the command room, on the big screen, there are detailed goals. The goals are broken down to the sky and specific to the person. It is clear what work each person has to complete every day.

This is based on the twenty-four hours of the day while on Earth.

Of course, on the two living planets in the Proxima Centauri galaxy, a day is not 24 hours long, and a year is not 365 days, because the rotation and revolution periods of the planets are different.

But they still use the time on earth as the unified time.

They are the pioneers of mankind and need to build a complete human base here to facilitate the arrival of humans later.

…

Time flies in the blink of an eye, and the year is 2048 AD.

This year, Cai Jin is 48 years old and middle-aged.

It just looks like there is no change now from before.

With the advancement of biotechnology, China has developed a life gene medicine. One injection can greatly extend human life to 150 years, and the aging period does not begin until the age of 120.

In the past, the two stages of youth and middle age only lasted forty years, with infants, teenagers, and old age accounting for more than half. However, now the two stages of youth and middle age last for more than a hundred years. This means that human beings Have longer study time and longer prime working hours.

As the person who created the life gene potion, Cai Jin was naturally the first to use it.

But even now, not everyone can use the life gene potion. They either have to pay a lot of money, make military exploits, or make contributions to society.

After all, up to now, the annual output of life gene medicine is only 10,000 doses!

In recent years, intelligent mechanical dogs have become very common in society. There are 30 million intelligent mechanical dogs and 7 million intelligent robots in the entire human society.

Many industries have been replaced by intelligent mechanical dogs and intelligent robots.

The whole society has completely changed. For example, home robots. Many wealthy families will buy a home robot, and then by purchasing a package, the home robot can sweep and mop the floor, buy groceries, cook meals, serve as a family doctor, etc.

Many restaurants also directly use robots.

Various types of intelligent robots have replaced many jobs.

As for social welfare, it has also been greatly improved compared to 12 years ago. Free medical care is available to all people. Even the laziest lazy people can get the most basic living necessities and will not starve to death.

Of course, those are just the most basic supplies.

Today Cai Jin and his family came to the capital. This time they came to welcome the warriors of the expedition.

A full 12 years have passed since we bid farewell to these galactic expedition warriors.

In fact, the spacecraft had arrived in the Earth's space orbit three days ago, but it did not land directly on the Earth.

Liu Yang and the others received medical examinations and recovered their health on the large space station.

Of course, it is also possible that someone with obsessive-compulsive disorder has to choose this day to return to Earth.

Twelve years ago today, these warriors set out from here.

And today, they return to Earth.

At this time, the entire space force base was decorated with lights and streamers, a long red carpet was laid out, the stage was set up, and there were flowers everywhere.

In order to welcome the returning warriors, the relevant departments took great pains to welcome them with the highest standards.

And they really deserve this courtesy!

This expedition to the Proxima Centauri galaxy brought back more information, allowing the earth to learn more about the Proxima Centauri galaxy.

The spaceship appears in the sky and then slowly lands at the designated location.

The cabin door opened, and the military band played the highest-level welcome song to welcome them back.

Liu Yang walked at the front, followed by the two deputy commanders, three in a row, who walked out neatly and then walked along the red carpet towards the stage.

The honor guards of the three armed forces paid their attention and paid attention to them.

Liu Yang and others were extremely excited. They had been away from the earth for twelve years, and when they came back this time, the country actually arranged such high-level courtesy.

The long red carpet, applause, cheers and flowers are dedicated to these brave warriors.

On the stage, the leaders are welcoming the warriors.

The return ceremony was broadcast live worldwide.

The main leaders of the Earth Alliance all gathered at this return ceremony.

In addition to the necessary personnel on duty, 300 people have returned and 250 people have returned to Earth.

The leader delivered a speech and spoke highly of this galaxy expedition.

On the big screen, what appeared was the Shennong star in the Proxima galaxy, as well as the scale of the human base.

"Man will conquer the sky! Heaven moves vigorously, and a gentleman will strive for self-improvement. The terrain is great, and a gentleman will carry it with kindness! There is no difficulty or obstacle that can stop our Chinese nation." The leader said with determination: "Even if the sun ages and expands into a red giant, Our Chinese nation cannot be destroyed, we have found our new home, and we will wander around the earth with us!"

Subsequently, these warriors were awarded the 'Hero of Humanity' medal. The medal was very gorgeous in shape and was carved from jade.

This is currently the highest medal in the world.

It will only be awarded and will make great contributions to the entire human race.

This is also one of the rare world awards that transcends countries and nations.

The words "Welcome home" made these warriors burst into tears.

The other 50 heroes who stayed on the Shennong Star said hello to everyone through pre-recorded videos, and also said hello to their families. These were all in pairs, and each pair had a child.

This is also the first time in human history that life has flourished on a planet other than the earth.

"Lao Zhang, how come you have become younger~~" Liu Yang was shocked when he saw her husband and daughter holding flowers.

My husband is exactly the same as when he was young.

Could it be that the spaceship is traveling too fast and time has gone backwards?

Zhang Hua presented flowers to Liu Yang, and then recounted the changes over the years. Only then did Liu Yang know that China had developed a life gene medicine that could greatly extend life. Because of Liu Yang, his family members all benefited from this and all had quotas for the life gene medicine. .

Liu Yang felt incredible and at the same time overjoyed. This meant that their family could be reunited, and it also meant that their careers could be greatly expanded.

In fact, Liu Yang felt very complicated when she came back this time, because according to their age, it was time for her and Wang Yaping to retire. Even though their spirits were still strong and their wills were still extremely strong, the decline in physical functions was an indisputable fact.

Now that the life gene medicine is available, it means that they can return to their youthful body functions and can also work on the front line in the aerospace industry, instead of relegating to the second line and doing aerospace propaganda.

Others were also extremely happy.

To be honest, when they embarked on the return journey, they were already prepared. Maybe some of their family members might have passed away when they returned to Earth.

But now I find that not only have my family members not died, but they have also become younger.

And some older people are already considering whether they are ready to have another child.

AD 2450.

In today's global climate, the lowest temperature is 30 degrees Celsius, and during high temperatures, it even reaches 80 degrees Celsius.

It has been many years since there has been any snow in the world!

The global population has also dropped sharply to 5 billion.

After more than 400 years of reproduction, China's population has reached 4.8 billion people, spread all over the world.

All planned underground cities around the world have been built.

All planned planetary engines have also been built.

Cai Jin is still young. As breakthroughs in life gene medicine continue to be made, human lifespan continues to increase. For example, Cai Jin's lifespan limit is as high as a thousand years.

And the thousand-year lifespan seems to be a bottleneck. Even if you have a golden finger, you can't break through this limit.

But Cai Jin is already very satisfied.

It is enough to be able to watch the implementation of this huge plan with my own eyes.

With the army maintaining order, people on the ground began to enter the underground city one after another.

Due to high global temperatures, the ice sheets have melted, and there is no more ice in the Antarctic and Arctic. Sea levels have also risen significantly, and many islands and coastal low-lying land have disappeared.

Even Cai Jin's hometown was submerged in the sea a hundred years ago.

Compared with more than 400 years ago, global sea levels have risen by a full 66 meters!

The opening of underground cities means that the earth is about to begin wandering.

In the underground command hall, thousands of staff are busy.

The situation of each underground city is constantly being reported.

In the past, drills were conducted on a city-by-city basis.

But now, it is really implemented.

"Report, all Chinese will be transferred to the underground city!" Finally, when everyone entered the underground city with their certificates, the person in charge reported.

"How about the planetary engine?" Cai Jin asked.

"All planetary engines are in good condition and can be started at any time!" the person in charge of the planetary engines replied immediately.

"How are the preparations for the space station?" Cai Jin asked again.

"The space station is all ready!"

"How are you preparing for the moon?" Cai Jin asked the last question.

After more than four hundred years of development, the moon's resources have been basically exhausted, and there are not many resources left.

Once upon a time, according to the plan, the moon was to move out of orbit.

But in the end, after several arguments, I thought it was best to keep the moon alive.

In the end, the moon will be transformed into a fortress. It will fly to a distance of 30 million kilometers from the earth and maintain an absolute distance from the earth. Space dust, comets, and small celestial bodies along the way will eventually hit the moon, thus protecting the earth.

"The moon is ready!" the person in charge of the lunar command center said firmly.

"The Wandering Earth Project, start!" Cai Jin's eyes showed determination.

Suddenly, according to the procedure, the moon's planetary engine started, pushing the moon out of its original orbit.

Finally, the moon was 30 million kilometers away from the earth, and the earth's planetary engine also started and began to leave its original orbit.

At this time, there are no more tides or ocean currents at the sea level on the earth.

As the earth moves away from the sun, the temperature within the earth's atmosphere begins to drop.

The speeds of the moon and the earth are increasing, but the distance between the two always remains 30 million kilometers.

Between the moon and the earth is a super-large space station. It is also the command center and the most elite group of people in China.

The super-large space station leads the earth's flight and becomes the connection hub between the lunar command center and the earth's underground command center.

The temperature of the earth continues to drop, and eventually it snows, and then seawater and rivers freeze.

Countless animals and a few people were frozen into ice sculptures.

On the ground, only a small number of troops remain. These troops are responsible for the operation and management of the planetary engine. Once a problem occurs, it will be repaired immediately.

The sea water froze, and many places that were originally submerged suddenly appeared again.

It is a pity that the once prosperous cities have been corroded by the sea water and have become completely different.

Cai Jin also bid farewell to his children on this day. Cai Jiye and Cai Yanyan, with their teams, each left the earth on the spaceship that Cai Jin built for them.

After all, the earth is too big. Even with so many planetary engines, the speed is always limited. They don't want to live in underground cities or space stations. They choose to explore further ahead.

A total of 365 spaceships are scattered around, protecting the earth.

Once it is discovered that a celestial body that is too large will impact, laser cannons will be used to bombard the celestial body.

The earth has entered an era of wandering. People of this generation live in underground cities. They can only understand the previous earth by watching TV series and movies.
