My science and technology museum

The first curvature light-speed spacecraft of the solar system civilization, the Golden Crow, sailed at twice the speed of light. After two years, it finally successfully approached the solar system and smoothly passed through the Kuiper Belt to reach the orbit of Neptune.

It’s different from when Xu Lei left.

Nowadays, the solar system has undergone great changes.

Although it has only been a few years, the Human Security Alliance has strictly implemented the development plan formulated by Xu Lei.

Implement the two-way flowering struggle policy.

Don't put all your eggs in one basket.

Vigorously build human civilization’s own galaxy defense force.

After all, Xu Lei made it very clear when he left the solar system. No one can be sure of the outcome of this trip to the outer galaxy, and he cannot place all his hopes on the Civilization Administration.

As the saying goes, to make iron you need to be strong, and a powerful fleet and planetary defense system are the core.

Compared to thirty years ago.

At present, cruise ships sailing everywhere in the solar system, as well as transport ships transporting various supplies, can only be described as lively.

After reaching the orbit of Neptune, what comes into view is no longer the vast starry sky, but a black structural defense ring. The whole is fully spliced, and heavy weapons such as laser energy and orbital running are also installed at intervals.

"I didn't expect the defense ring project to progress so quickly, which is a bit surprising."

Earth ephemeris.

November 20, 2053.

Thursday.

A node in the solar system defense ring.

In the cab of the Golden Crow's light-speed curvature spacecraft, Xu Lei faced the magnificent space project in front of him and glanced at the time on the screen with emotion in his heart.

I remember that the defense ring project was still under construction when he first left.

It now has preliminary defensive functions.

Although there are still weak nodes in the defense ring that can be found through spacecraft space radar scanning, it is already a miracle for humans to reach such a point.

It is no exaggeration to say that it is the largest project in history.

It can only be said that more than one billion mechanical life forms have achieved all this.

Ordinary carbon-based humans need to wear heavy space suits if they want to work in the space environment.

And there are many limitations.

Its efficiency must be very low.

But the new humans with amorphous alloy mechanical bodies are completely different.

They can lock themselves directly into the defensive ring and perform efficient operations.

Naturally, the ring belt can be built quickly.

Xu Lei was very pleased to see that the solar system was still developing rapidly after leaving him. This showed that everything he had done was worthwhile and that human civilization already had the potential and qualities to be promoted to a higher civilization.

It is also worth mentioning that Xu Lei did not choose to force his way through the defensive ring.

Although it can be easily done relying on the speed of the Golden Crow.

After actively initiating the application in accordance with the prescribed regulations for entering the solar system, a familiar voice was heard in the cockpit.

"You have entered the security defense ring of the solar system. This is the Space Command of the First Fleet of the Human Security Alliance. Please report your identity and state your intention, otherwise we have the right to forcibly evict you."

"repeat."

"Please report your identity and purpose of coming?"

"repeat."

"Please report your identity and purpose of coming!"

"Otherwise we will attack."

Living in alien galaxy civilizations tens of thousands of light years apart, although we can occasionally hear Chinese from the mouths of alien beings who like the solar system's language system, it is far less cordial than those of the same kind.

So at this time Xu Lei no longer hesitated and followed the process directly.

"Human Security Alliance Councilor Xu Lei, please go home."

As he said this with a slightly vibrato tone, a response soon came from the cockpit again.

"The identity verification is correct."

"Congressman Xu Lei, welcome home."

And almost at the same time as these words were heard, the defense ring in front of them automatically opened, and the node was in normal traffic status.

By this time, Xu Lei's homesickness had reached its extreme. He wanted to reach the Earth Star immediately, and had no patience to stay any longer. So he restarted the spacecraft engine the next second and headed towards the Earth Star at an extremely fast speed.

at the same time.

After the news of Xu Lei's return was conveyed to the Human Security Alliance headquarters, all the members were extremely excited and set out to meet Xu Lei as soon as possible.

It seems that the entire human civilization has been mobilized because of Xu Lei.

For other members of the alliance, Xu Lei is undoubtedly the backbone of civilization.

During Xu Lei's absence, although the construction of various space projects was progressing rapidly, everyone was unsure.

There is no complete certainty to deal with the Herald Empire fleet.

Especially as time passed and no news came from Xu Lei, everyone's mood became more and more depressed, fearing that Xu Lei would be in danger during the process.

But it's fine now.

Xu Lei successfully returned to the solar system.

Success brings light to their originally gloomy hearts.

In addition, there is one more thing that must be mentioned.

When Xu Lei took the Golden Crow to Proxima Centauri, he did not inform the public.

This approach is adopted mainly for the sake of the stability of civilization and to save people from worrying about future development.

Let the situation worsen.

Now that Xu Lei has returned safely, he will definitely hold a press conference to disclose relevant information about the Galaxy Civilization Administration to the public.

…

"What are you talking about? Councilor Xu Lei is back!?"

Alliance for Human Security.

First Fleet.

Space Command.

Fleet Captain Lei Zhan, the then commander, suddenly stood up from his seat after hearing the news, as if there were only two words written on his face.

Excited.

excited.

When it comes to his feelings for Xu Lei, Lei Zhan is undoubtedly much deeper than Zhang Jingtong.

He first relied on the future technology of neural connection prosthetics to repair his arm, and later became the first human in the world to complete the uploading of consciousness. Now he can become the commander of the first fleet of human civilization, and it is even more inseparable from Xu Lei's layer relationship.

To put it simply, his achievements today are all due to Xu Lei's promotion.

During Xu Lei's absence, he was worried day and night.

But because he had no choice, he had to be more responsible for the safety of the solar system and lead the space force to build a defensive ring.

And today is undoubtedly the happiest time for him in recent years.

"Yes Commander."

"According to the information given by the defense ring, Councilor Xu's Golden Crow passed Node 26 just now." His subordinates, who had not seen Lei Zhan's performance for a long time, were also happy from the bottom of their hearts, and immediately blurted out all the details. information.

Hearing this, Lei Zhan could no longer calm down.

While arranging his cabin clothes, he said to his subordinates: "Congressman Xu Lei will definitely return to the Earth Star when he comes back this time, and prepare a battleship for me immediately."

After several years, Xu Lei finally returned to the solar system safely. Under such circumstances, Lei Zhan couldn't sit still.

Will go back and have a look anyway.

The subordinate next to him naturally had no objection to this, and immediately replied excitedly: "It's the commander, I'll go and prepare right away."

Soon when the other party's figure disappeared from sight, Lei Zhan seemed to have thought of something again, and then murmured thoughtfully: "I wonder if there will be any surprises when Representative Xu Lei returns to Earth Star."

The perspective comes to Earth Star.

Binjiang City.

Longhu High-tech Park.

In the president's office of the Space Battleship Headquarters Building, Chen Shihe, dressed in a red suit, sat at his desk and was busy working.

In the second year after Xu Lei left the Earth, the Lunar Taiyin City Scientific Research Department, under the auspices of Qin Xiaoman, successfully used the pioneer's own genes to synthesize a new type of medicine that could completely improve the shortcomings of human beings threatened by the death substances of the Earth.

To put it simply, as long as you inject this new medicine, you can live a normal life on Earth like a pioneer.

This announced that humans had reoccupied the Earth planet after many years.

As soon as this news came out, it immediately aroused heated discussion among the public and the emotions were extremely high.

Mainly living on extraterrestrial planets such as the moon and Mars, the lifestyle is completely different from that of the earth, and there is a huge discomfort.

Even if the body can adapt to the new environment with the help of strengthening medicine, the yearning for the earth star will always remain in his heart.

They all want to return to life on Earth one day.

Under this circumstance, the Ministry of Future Science and Technology did not disappoint the public's expectations, and immediately began to produce this new medicine at full speed and injected it into the residents of Mars City in Taiyin City.

Return to Earth Star in batches.

Now the earth star has long been restored to its former vitality.

One billion permanent residents.

At the same time, mature cloning technology is also used to gradually resurrect the biological species on the planet.

Especially sea life.

It can be said that everything is developing in a good direction.

As for the new humans with amorphous alloy mechanical bodies, they will settle on the moon, Mars, and the newly developed Saturn satellite base. This will also be able to better utilize the advantages of mechanical life and speed up the construction of human space super projects.

With the future technology headquarters moving back to Earth and the gradual transformation towards genetic pharmaceutical biological cloning, the business has become larger and more complex.

It's like a giant machine that never stops.

But even in the face of such great pressure, Chen Shihe never complained.

He just resisted the entire company.

And the company's business development still shows an upward trend.

Fortunately, with Xing Tong assisting him, there were no accidents.

At this time, a knock on the door sounded from outside.

"Please come in."

Chen Shihe slowly uttered two words upon hearing the sound, but his eyes remained on the desktop files.

Xingtong pushed open the door and walked quickly to the desk, then said: "Shihe, boss, he is back and should arrive at Dixing soon."

Xing Tong, who has long been born with self-awareness, is no different from the new human beings in Chen Shihe's eyes. Coupled with the special relationship between Xing Tong and Xu Lei, she has always treated her like a sister, and her daily communication is very direct and without too much etiquette.

However, Chen Shihe, who had always been calm, straightened up suddenly after hearing these words, and couldn't wait to ask: "Xu Lei is really back, is it true?"

"That's right."

"The First Fleet Space Command has determined that it is the Golden Crow."

Faced with Chen Shihe's performance, Xingtong seemed to have expected it and still answered without changing his expression.

After finally confirming the news about Xu Lei, Chen Shihe no longer concealed his inner emotions at this moment, and the corners of his eyes became moist almost instantly.

"Very good."

"It's really great."

"I knew he would be fine."

I kept repeating these words in a daze, feeling like I was crying with joy.

But she quickly came to her senses and quickly said to Xingtong: "First of all, postpone or cancel all my schedule for today. Also, I have to go home quickly and tell my parents and Xuanxuan the news as soon as possible. .”

After saying that, he didn't bother to wait for Xing Tong's answer, so he quickly stood up and walked outside.

In response, Xingtong just stared at Chen Shihe lovingly, until the figure completely disappeared from sight, then a smile appeared on the corner of her mouth.

——

Relying on the Golden Crow's flight speed, even if it doesn't turn on all its power in the solar system, it won't take long to reach the Earth.

When the blue planet comes into view again.

He suddenly felt that all the previous efforts were worth it.

"The development of human civilization is really changing with each passing day. The scale of the space shipyard has expanded several times."

Moving his gaze to the nearby low-Earth orbit space shipyard, he saw that the size of the original shipyard has increased many times, which means that the production speed of warships will also increase exponentially.

Facing more and more surprises, I feel very happy.

However, he did not choose to change his route to inspect the space shipyard.

After a moment of emotion, he restarted the spacecraft.

Directly through the Earth's atmosphere.

Driving quickly towards the location of Binjiang City.

Because Future Technology had already received the news, many people spontaneously came to the square in front of the headquarters building before the Golden Crow arrived.

Let’s welcome Xu Lei’s return together.

With a casual glance, you can see many familiar figures.

For example, Chen Shihe.

Xu Lei’s father and mother.

As well as the company's core personnel Jia Zhongjie, Lu Hongbo, Liang Fuxing and others.

There are also dozens of research institute personnel Li Chengzhe and Qin Xiaoman who have returned from the moon to the earth.

As for Lei Zhan, Zhang Jingtong and the others, because they are far away from the Earth Star and the cruiser's sailing speed is limited, they will not be able to return to the Earth Star for a while.

After all, the speed of a battleship cannot catch up with the speed of light spacecraft.

But what is strange is that there is a five or six-year-old girl standing next to Chen Shihe.

Tie two small knots.

The face looks like a porcelain doll and is very cute.

Although she didn't quite understand what she was doing, she still stood beside her mother obediently, looking very well-behaved.

Not long after.

Under everyone's gaze, an elegant figure soon came into view.

Then the roar of the engine came to my ears.

It was the Golden Crow driven by Xu Lei.

The originally quiet crowd became completely lively.

"Look, it's Mr. Xu's spaceship."

"As expected, Councilor Xu is back. It's great."

"Today is a good day."

"Mom, is that dad?"

…

When the Golden Crow stopped smoothly in the square in front of the headquarters, Xu Lei came out of the cockpit and felt a little dazed when he saw the welcoming crowd not far away.

Because in his impression, Earth Star is a forbidden area for ordinary humans.

Even when wearing protection, going to Earth Star is still very dangerous.

But now everyone is gathered here.

and not wearing protective clothing.

Xu Lei's first reaction in this situation was that they all uploaded their self-awareness and became new mechanical humans.

Thinking of this, he couldn't help but frown.

The development of human civilization should not completely abandon the body. The correct direction should be genetic optimization. The current semi-mechanical and semi-carbon-based structure is completely caused by emergencies. If you do not upload your consciousness and transform into a mechanical body, you can only wait for death.

Even he himself is like this.

If it weren't for the fact that his own brain was too highly developed, an ordinary body wouldn't be able to bear it.

He will never upload his consciousness easily.

Fortunately, he was lucky enough to encounter living gold, a special active metal, which gave him a chance to condense an eternal body.

Become a special life form.

But his dissatisfaction did not last long.

As he approached them, he realized that they were still ordinary carbon-based life forms.

It's not a mechanical body.

This made him even more confused.

Don't know what happened during his absence.

"Is everyone okay?"

Finally, Xu Lei stood half a meter away from everyone and said this greeting from the bottom of his heart.

"Dean, we all miss you very much." Li Chengzhe, then deputy director of the Future Science and Technology Nuclear Research Institute, was the first to respond, with a smile on his face.

At this time, Qin Xiaoman, who was next to him, seemed to see the confusion in Xu Lei's eyes, and then took over the words and explained: "Dean, I finally lived up to your expectations. We have successfully developed a drug that can be immune to the death substances of the Earth." Potion, now humans have returned to the Earth Star."

Although Xu Lei had vague speculations in this regard, he still couldn't restrain his excitement when he heard Qin Xiaoman's confirmation with his own ears.

Unexpectedly, this regret was solved by the scientists he trained.

You must know that he originally thought that after his influence was enough, he would look for technological exhibits in the science and technology museum to solve the problem of the earth and the stars. Unexpectedly, this regret would disappear before the matter was done.

Facts have proved that human beings have great potential.

As long as it is properly guided, it can perform very well.

Qin Xiaoman is the best proof.

Crucially, this also saved him a lot of influence.

Faced with such a happy event, he naturally would not be stingy with his praise and immediately replied: "I knew you would succeed. This is not only the pride of future technology, but also the great pride of the entire human civilization."

"This is what I should be the dean of." Hearing that his achievements were recognized, Qin Xiaoman was happy but remained humble.

Always treat Xu Lei as the dean.

Obviously, in her mind, Xu Lei was not a member of the alliance who was in charge of the destiny of human civilization, but a dean who supported future generations and trained scientific researchers.

for the rest of the time.

Xu Lei also expressed his condolences to the core management personnel of the company.

After also affirming their contributions to the company over the years, he finally focused on his parents and Chen Shihe.

"It's good to come back. It's just that Shihe has suffered a lot these years." Xu Lei's mother held her son's hand tightly and did not forget to speak for her daughter-in-law.

His eyes soon became moist.

In response, after Xu Lei withdrew his palm, he immediately reached out and gently touched Chen Shihe's face. His eyes were full of distress: "I have made you suffer, how are you all these years?"

"I don't feel tired just thinking about you."

Chen Shihe touched the palm of his face, his eyes full of tenderness.

But the next second she seemed to have thought of something, she quickly picked up the little girl next to her and said after hearing the voice: "Xuanxuan, call daddy quickly."

Although it is blood.

But since the two parties met for the first time, their expressions seemed a little dull.

It's just big eyes staring at small eyes.

Each other loves each other a lot.

Chen Shihe said this before Xu Lei left Earth Star. After all, leaving a descendant to his parents is a comfort to their spirits.

So he knew the existence of the little girl in front of him.

It's just that the sudden change in identity will make you feel a little overwhelmed for a while.

But after all, he was also a father, and he couldn't let a child speak first, so after a slight hesitation, he took it from Chen Shihe, held her in his arms, and asked aloud: "Her name is Xuanxuan?"

"Well, it was our dad who got the name." Chen Shihe nodded.

Xu Xuan felt her father's embrace without any intention of struggling.

It was like accepting it instantly.

The main reason is that after Xu Lei fused so many living gold particles, his body has almost reached semi-living gold state, and the substances emitted by his body have a considerable strengthening effect on carbon-based life.

It will make the carbon-based life that is close to you feel at ease.

And after experiencing so many big and small things, feeling the almost negligible weight in his arms at this moment, he had an unprecedented feeling.

So much so that I am completely unwilling to let go.

Even if Li Chengzhe, Qin Xiaoman, and Lu Hongbo dispersed on their own without disturbing Xu Lei and his family's reunion time, Xu Lei always held Xu Xuan in his arms. When Chen Shihe saw such a scene, the smile on his face became brighter and happier.

After all, when she first learned that Xu Lei was back, she felt a little uneasy.

I was afraid that Xu Lei would not like Xuanxuan.

Facts have proved that the relationship between father and daughter is very good.

However, given Xu Lei's status, it is destined that it will be difficult for him to enjoy stability for a long time, at least not at this stage.

Not long after, Xingtong came over.

And bring a message.

"boss."

"Many alliance members have arrived, and Lei Zhan, Zhang Jingtong and others are also on their way back."

"They want to meet with you."

After listening to Xingtong's words, Xu Lei knew that the congressmen were here because of the affairs of the Galaxy Civilization Administration and wanted to know the specific situation and results.

After all, this concerns the fleet of the Pioneer Empire.

Although Xu Lei really wants to be stable for a while and spend time with his family, he should tell everyone the good news first so that everyone can settle down and pursue development.

So after thinking for a moment, Xu Lei gave Xingtong an order: "Let's arrange for them to settle down first, and then hold an alliance meeting after everyone has arrived. We will also prepare to hold a civilization-wide press conference."

"Okay boss."

Although Xu Lei handed Xingtong to Chen Shihe before leaving, Xingtong, who has self-awareness, will still obey his orders unconditionally.

that's all.

After alliance members from various regions waited patiently in Binjiang City for a period of time, Lei Zhan, Zhang Jingtong and others stationed at the Space Command finally returned to Earth and went to Longhu High-tech Park to attend the first offline meeting of the Human Security Alliance. .

In the past, alliance meetings were held online through virtual helmets for convenience and speed.

And everyone is used to this method.

Now, taking this opportunity, all the congressmen have come together to participate in the alliance meeting offline, which is quite a novel experience.

At the same time, the outside public does not know that Xu Lei, who has disappeared from everyone's sight for a long time, is about to drop a bombshell to the entire human civilization.
