The entire alliance's first fleet set off from the earth and skimmed over the moon and Mars and finally returned to complete the mission, drawing a successful end to this ultra-high-standard global military parade.

At the same time, it also makes the people deeply aware of their own strength, and the pride of civilization is stronger.

After Xu Yun took charge of this task, he continued to devote himself to the front line of scientific research.

Research and development of new technologies.

In order to ensure that technology can keep up with the development of civilization.

And the more immersed you are in something, the faster time tends to pass.

Twenty years have passed in the blink of an eye.

During these years, Xu Yun took the lead in presiding over the construction of a new warship manufacturing base and a maintenance base.

This greatly increases the production speed of warships.

Up to now, the Alliance for Human Space Security has established the Alliance's Second Fleet and Third Fleet.

The total number of warships with it is more than fifty units.

The development and utilization of lunar resources has entered a mature and stable stage, which can ensure the demand for nuclear fusion reaction fuel.

In addition, the alliance has also officially opened starship tickets, which can be purchased to travel to the moon and Mars by taking a battleship, especially entering Mars City to experience a different life from Earth.

Yes.

After 20 years of development, Mars City has not further expanded in scale and issued new resident quotas, but it has opened up the access of others to create alternative tourism.

It can be said that Mars City is already quite prosperous at the moment.

At the same time, it is precisely because of the residents of Mars City that the Starfire project is going very smoothly.

So far, the factories built on Mars have successfully raised the temperature of Mars by emitting greenhouse gases, which is basically within the originally expected range.

The permafrost on Mars begins to melt and release carbon dioxide.

In some ways, this is equivalent to the successful completion of the first phase of the Spark Project.

Although the wish for Mars to truly live and breathe freely is still far away, the entire scientific community is still very happy and excited about the news.

Just because it's a lot earlier than expected to take.

What's more worth mentioning is that Xu Yun led a team of scientists to successfully conquer the hibernation capsule.

This allows the crew to speed up by autonomously hibernation when performing long-term missions in space.

Avoid spending a lot of time on a battleship to disturb your spirits.

This technological breakthrough has also allowed human civilization to successfully possess the ability to conduct long-distance interstellar voyages.

The importance is self-evident.

At present, the newly formed Third Fleet of the Alliance, all warships are equipped with such dormant cabins.

It can be called the trump card in the fleet of human civilization.

Meanwhile.

In the independent office of the councilor at the headquarters of the Earth Alliance, Xu Yun, who was full of silver hair, sat on the sofa and made tea himself, and opposite was the older Academician Zhou Mingwei.

Xu Yun is 70 years old this year.

Normally, the retirement age has long been exceeded.

However, because he was not assured of the project and the retention of the alliance, he still held the position of chief scientist of the alliance.

and Honorary Members of the Alliance for Life.

However, it may be because he had used active potions before, but he felt that he was in good health.

At least much better than other peers.

It is precisely because of his young mentality that he has never dyed his hair even if it gradually turns silver white.

"Your tea-making skills are getting better and better, I don't know how many times I can drink it." Zhou Mingwei shortened the teacup in front of him and put it to his mouth, and said to Xu Yun with a smile after tasting it.

He is already ninety years old, and he has long since retired as an old man.

At this age, it is basically possible to die at any time, and old friends from the past can only see one side and less side.

So even if his legs and feet began to be a little inconvenient, he would still find time to meet Xu Yun, Zhang Feng and others.

Xu Yun listened to this sentence in his ears, and he couldn't help but feel a little sad in his heart.

Although human beings have overcome various major diseases, the average life expectancy of residents has been greatly improved.

But when it comes to ninety-one hundred, there is still no escape.

From this point of view, what Zhou Mingwei said is not wrong at all.

may not want to talk about this kind of sad topic, Xu Yun immediately turned around and joked: "When the project on hand in the past two years is over, I should also consider retiring and enjoying my old age." ”

There is nothing false about what he said.

Son Xu Ziyan fell in love and got married freely at school, and now his grandchildren are quite old.

And Xu Ziyan has indeed fulfilled his promise, and now lives on Mars with his wife for a long time to be responsible for the Mars transformation project.

The grandchildren are all brought by him and Chen Shihe.

However, the eldest daughter Xu Ningxuan still has not chosen to get married.

Almost all the energy is put into the company.

Because of this, Chen Shihe talked a lot, and also introduced blind dates like other parents.

Unfortunately, the results did not change much.

Xu Yun saw this quite openly.

As the saying goes, children and grandchildren have their own children and grandchildren, and sometimes they can only choose to follow their children's ideas.

When Zhou Mingwei heard that Xu Yun was also going to retire, a smile suddenly appeared on his face and waved his hand again and again.

"I don't believe you want to retire, the alliance alone shouldn't be willing to let people go like this, right?"

In recent years, although the rapid development of civilization has promoted the reform of education, many outstanding scientists have been trained for the alliance.

But no one can compare with Xu Yun.

It is no exaggeration to say that Xu Yun is now like the Dinghai Divine Needle of human civilization is a spiritual symbol, and it is completely normal for the alliance to be reluctant to release people in this situation.

Xu Yun seemed to have thought of something when he heard this, and took the initiative to end the topic in the next second.

"Let's not talk about this today, how is Lao Zhang doing?"

"Him."

"It's hard to get into the ground right now." Zhou Mingwei said sympathetically when he heard Xu Yun mention Zhang Feng.

The two of them are about the same age, and he is already relatively lucky that he can still walk on the ground.

After all, they are all in their nineties, who can be better.

"I'll see him another day." Xu Yun naturally knew Zhang Feng's situation, and paused in response.

Just as the two of them continued to drink tea, they heard a sudden knock on the door outside the office.

"Please come in."

As Xu Yun's words fell, a man in blue scientific research uniforms pushed the door and walked in, about forty years old and wearing a pair of glasses, he looked polite.

Xu Yun and Zhou Mingwei were obviously very familiar with the visitors, and immediately greeted them after raising their eyes.

"Xiao Liu is here, sit down and drink tea together."

"Would you like a drink?" Xu Yun gestured to the teapot in his hand and said.

Xu Yun is quite satisfied with the scientist in front of him, and the other party, as his deputy, can be said to be what he picked up and stayed by his side to cultivate and teach.

And the performance of the other party did not disappoint him.

As he gets older, he will let the other party do many things.

Give the other person a chance to grow.

However, Liu Rui did not sit down to taste the tea in the face of Zhou Mingwei and his teacher's invitation, but walked forward a few steps quickly, and said to Xu Yun with a serious expression:

"Teacher, there is a situation in the control center, let you go as soon as possible."

"Is there a situation?" Xu Yun was quite surprised.

The control center monitors all warships and space equipment, and under normal circumstances, nothing happens.

Unless there is an early warning of problems with the warship, the center will pay attention to it.

Like some small things, he can handle them by himself, and basically can't report them to him.

But now the control center is in a hurry to let him over, which is obviously not an ordinary situation.

It's just that he is more aware of the situation of the warships currently in service in the alliance, and when they are not yet close to the end of their service life, there should not be any more serious accidents.

His brain turned quickly, and seeing that he had no clue, Xu Yun stopped delaying time.

"Then I'll go over and see how it goes, and you drink here first."

"Go get busy."

got up and said to Zhou Mingwei, and followed Liu Rui to the hall of the control center.

Zhou Mingwei looked at Xu Yun's back, and did not turn around again until his figure completely disappeared from sight.

He was already surprised by this.

You must know that he knows Xu Yun's situation best, although he is now seventy years old, there are still not many times when he is usually relaxed.

The nascent team of scientists still needs to ask Xu Yun for advice when faced with unsolvable problems.

Therefore, Xu Yun's status in the alliance is also rising more and more.

——

Xu Yun and Liu Rui soon came to the hall of the control center, and as soon as they walked in, they found that the people in the entire hall seemed to be very busy, and they could see the scene of many people running back and forth.

So seeing this, he could no longer suppress the curiosity in his heart, and immediately asked the person in charge here about the situation.

"What's going on?"

"Old Xu, you can count it as coming." After hearing the voice, the person in charge who was standing there looked up and saw that it was Xu Yun, and suddenly seemed to have grasped a life-saving straw, and hurriedly walked over to greet him respectfully.

For the honorific title of Xu Lao, Xu Yun is also basically used to it.

Whoever made the people in the Alliance Academy of Sciences have become his juniors.

There's no way around it.

"Give me the details." Xu Yun didn't have the patience to talk to the other party about irrelevant topics, so he immediately got straight to the point.

At this time, the person in charge naturally did not dare to hide anything.

Even if there is a report on what happened.

"That's like this, Elder Xu, we just detected the signal of the aircraft outside the solar system."

"Aircraft signals?"

After Xu Yun understood the situation, the whole person was stunned at first, and then a joy surged in his heart.

Calculate the timeIf the Voyager 3 mission goes well, then it should return to the solar system according to the original route.

Now that a signal has been detected in the outer reaches of the solar system, it is likely to be Voyager 3.

Keep in mind that Earth has been out of touch with Voyager III for a long time.

No one knows if Voyager III is still in operation and whether it will be able to fulfill the mission given to it by human civilization.

This matter is also Xu Yun's biggest knot.

I didn't expect my luck to be so good, and I really witnessed the return of Voyager 3 from Proxima Centauri in my lifetime.

The thought stayed here, and he couldn't hold back the excitement in his heart any longer.

Hurriedly asked the other party: "Have you established contact with the other party to confirm its identity?" ”

"Not yet." The person in charge replied with some weakness, and then questioned in a low voice: "Because according to the scheduled time, Voyager 3 should not have returned to the solar system." ”

The original voyage of Voyager 3 was carefully calculated, and the approximate time of the normal return voyage was basically determined.

Now that the signal has been detected in the outer reaches of the solar system, the timing is indeed a bit out of place.

And if the detected signal does not belong to Voyager 3, it means that it is likely to be an alien spacecraft, so it is definitely not possible to establish contact rashly without knowing the purpose of the other party.

When Xu Yun heard this, he almost didn't have to think about it to guess the other party's worries.

But what the other party didn't know was that in the environment of a strange universe, it was normal for Voyager 3 to return early or late.

In addition, it is just a flying machine, even if it is really an alien spaceship, with the strength of the current human fleet, there is no need to worry at all.

So he didn't have anything to worry about about this matter, and directly issued an order to carry it out.

"Let's try to make a connection and identify this craft as soon as possible."

"Personally, I think it is more likely to be Voyager III, and the Third Fleet will be arranged to go to the outer reaches of the solar system to stand by and be ready for combat at any time." In the end, out of insurance, Xu Yun arranged one more item.

If a formal order is issued, the other party will definitely not say anything more, and even if it is implemented.

"It's Old Xu, I'll arrange it."

At this time, Liu Rui next to him couldn't help but ask: "Teacher, what do you think is the probability that this unidentified aerial vehicle is Voyager 3?" ”

When Voyager 3 set sail, he hadn't yet entered the Alliance Academy of Sciences to work on projects, so he didn't know much about the more confidential situation.

But as a scientist, I must hope that Voyager 3 will actually bring back information from Proxima Centauri.

This is essential for the study of extragalaxies.

Xu Yun knew very well what Liu Rui was thinking, raised his eyes and glanced at the other party, and then said in a soothing tone: "I hope it's Voyager III, after all, this is my last chance to study Proxima Centauri, and if I finish this, I really don't have any regrets." ”

"I also think that there is a high probability that it is Voyager III, as long as we establish a connection here, we will be able to confirm the identity soon." Liu Rui nodded immediately after hearing this.

That's it.

The two of them didn't leave the rest of the day.

Always stay in the hall and wait for the final result.

As for the Third Fleet, which received the order, it immediately set off at full speed and headed for the outer reaches of the solar system.

In this way, even if it is determined to be an alien spacecraft, it can be controlled or destroyed in the shortest possible time, so as to avoid the impact of the battle from spreading to Mars, the moon and even the earth.

As time gradually passed, when Xu Yun and Liu Rui waited patiently, they only heard an excited voice suddenly sound in the hall, which immediately attracted their attention.

"Is that confirmed?"

"Good news Elder Xu, your judgment is not wrong at all, I just received the information from the other party, and I can be sure that this is our Voyager No. 3." Before Xu Yun got up to ask, the person in charge had already come over to explain the situation, without hiding the excitement on his face.

And it was only at this time that Xu Yun finally breathed a sigh of relief, and then a smile appeared on the corner of his mouth and said: "Announce this news and let everyone get ready to welcome our heroes." ”
