That's it, three months is not a long time, but it feels like it has passed in the blink of an eye.

Deep Space's velocity had reached 3 times the speed of light, and then began to decay rapidly, all the way to sub-light speed.

All the plans went according to plan, and nothing too big was going on......

By the way, it's just that recently, there is one more plan for the manufacture of frigates!

In the face of this manufacturing plan, scientists are also gearing up...... They just have nothing to do, anyway, building a few frigates, there is no big problem from a technical point of view.

The drawings of the first phase were quickly designed, and according to the scientific and technological strength and industrial standards of the Noah, the model machine could be built in a few months.

……

On this day, Yu Yifeng was working normally in the office, and after he made a conference call, he habitually clicked on the next document.

Suddenly, he noticed that the computer screen was already blank.

"Huh...... Don't have any papers? ”

He re-read it a few more times, only to realize that all the documents were marked "processed" and there were no new emails in the mailbox.

He's done all the work!

Yu Yifeng scratched his head, and suddenly felt a little uncomfortable, so he suddenly relaxed, and he felt that every muscle in his body was aching and aching.

I'm so tired, when was the last time I finished handling all the work?

It seems like it's been a long time since I've rested, right?

The first medium- and long-distance voyage of mankind seemed to be going well, and with all the work done, his nerves, which had been tense for many years, slowly relaxed...... Finally have the kung fu to catch my breath!

Just thinking about it, the tiredness came like a tidal wave, and he felt an extreme sense of drowsiness.

It is also said that he is too busy for the entire Deep Space project, a cycle of 160 years.

As the leader of civilization, not only do many internal affairs require him to be in charge, but there are also various issues of population distribution and resource allocation. He suddenly appeared on the surface of the planet Knicks, and suddenly flew back to the Noah, and he was busy all the time even during the New Year.

Even...... The sudden appearance of certain important technologies will also keep him busy for a while.

Because of these reasons, he and Yuriko are also less together and more separated......

The two have not been together for much time, and they have never had offspring.

Of course, the question of future generations is not just because of busyness, there are other possibilities......

Yu Yifeng even had some doubts, is it impossible for superhumans to have children?

It's really possible!

According to some animal experiments, after installing a brain chip in some dogs, the success rate of perfection modification can reach 80%-90%.

As a result, humans have harvested more than a dozen super dogs with outstanding abilities......

But these super dogs have never bred offspring, including the first super dog "Big Black".

Because the success rate of the experiment cannot be increased to 100% for the time being, Perfection has not been popularized in humans on a large scale.

The new government is not willing to lose 10%-20% of the population because of this...... When the natural life span is up, there is no way to go further, everyone will be willing to try it, and perhaps with the improvement of the brain chip, the success rate of future experiments will be higher.

As for the issue of Yi Feng's descendants, scientists have studied it for a long time, but they have not come up with any good results......

"Transhumans and humans will theoretically not be reproductively isolated. But it's weird...... The fertilized eggs formed seem to have lost their totipotency and are unable to divide and differentiate. ”

"The seeds of super plants also have such a problem, the reproductive ability is very low, and many of them cannot germinate...... But there are very few that can succeed. ”

"So we speculate that after the super individual is combined with humans, the reproductive ability is very low, which is a big disadvantage......

Perhaps out of a desire for a child, or perhaps a desire to be smarter, Yuriko finally mustered up the courage to accept the experiment of perfection.

Even if Yu Yifeng repeatedly stopped her, he couldn't persuade her.

Fortunately, the results of the experiment were successful, and the 80% success rate was not low, and she successfully became a superhuman......

However, two superhumans...... Still no children were born.

Well, these questions will not be discussed for the time being......

If superhumans are indeed low in reproductive ability, then it is indeed a problem to convert ordinary people into a large area, and it is really not possible at this time period.

The government intends to wait for the population to reach 5 million, and the technology will become more advanced, and it will be converted all at once.

After all, the share of Perfection is only six million, and if there is too much population and unfair distribution, it is not good.

Yu Yifeng shook his head and gave up thinking about this kind of problem.

At this birth rate, the population reaches five million, and I don't know if it will be the year of the monkey......

He was wondering if he was going to take a few days off and get some rest......

Not only him, but many people's nerves are slowly relaxing.

Especially the old guys of the first generation, they have struggled for so long and taken a decisive step. It's quite a sense of accomplishment to see this huge battleship alive......

After all, civilization is slowly pushed in its own hands and becomes stronger!

"Deep Space" is the sustenance of wisdom, sweat and feelings!

In the course of this voyage, this human remnant felt relaxed and happy for the first time.

Yu Yifeng rubbed his sour temples and lay down comfortably on the chair.

In the past 100 years, the overall improvement of individual morality and social hierarchy has gradually arrived, and the era of freedom has gradually arrived.

People can do what they want to do without being constrained by the question of "survival".

The inertia of work and beliefs and ideals that have been maintained for more than 100 years have become ironclad facts.

Especially the later generations, their education is not the same as that of the Earth period. For these generations, work and "ideal goals" are necessary and part of life.

"Science" has become the highest belief for many people, and people can get a lot of pleasure from their work...... Especially in this golden age of technological explosion, it has become a little difficult to think of results.

That's it...... The government can only impose specific working hours, and cannot work too late, because there are too many workaholics.

And because the brain chip has improved from generation to generation, everyone has become smarter, so much so that more than 70% of the population is scientific researchers, including scientists, engineers, and so on.

The rest of the population is doctors, teachers, soldiers, and the like, which is also determined by the atmosphere of the new human civilization.

"To celebrate the smooth operation of the Deep Space, I propose a few days off, 3 days off for everyone, how about this proposal?"

Yu Yifeng made a conference call, but no one responded to this proposal.

In the end, it was the Minister of Security Xu Yunjin who broke the ground.

Xu Yunjin said with a smile: "Old Yu, if you want to rest, go by yourself, everyone knows that you are hard, we don't need to rest!" We've got a weekend! ”

"Hurry up and have a son! Your wife is dying! ”

In the midst of laughter, Yu Yifeng walked out disgraced...... In retaliation, he temporarily threw all his work affairs to Xu Yunjin.

"Just take a day off, three days is too much!"

Yu Yifeng finally made up his mind, and he directly dialed Yuriko: "I'll have a day off tomorrow, how about we go out to play?" ”

"Huh? What did you say? We're testing...... Ion Accelerator ...... Test ......" Yuriko's voice came over the phone. The signal was intermittent and may have been affected by some of the experiments.

Faintly, Yu Yifeng heard the unique sound of high-voltage current. He felt like he could imagine what it would be like in the lab.

"Okay, you guys go ahead...... Stay safe. ”

He shook his head, hung up the phone, edited a text message and sent it.

After a while, the other party replied: Tomorrow off, really? ”

"It's true, go out and play, right?"

This time the reply was quick, but there was only one word: "Good!" ”

Although the reply was very simple, you could feel the enthusiasm and surprise of the other party.

Speaking of which, they have never hung out together since they got married. I don't have time, I can't even think about a honeymoon or anything......

Thinking of this, Yu Yifeng felt a little guilty in his heart......

A quiet night.

The next morning, at 7 o'clock, Yu Yifeng instinctively opened his eyes and wanted to get up and dress, but was forcibly pressed back by the girl next to him.

He immediately smiled, remembering that today was a day off, and he gave himself a holiday......

I'm still a little unaccustomed to waking up late.

"Do you just sleep in bed? Sleep for a day? Yu Yifeng asked.

"Isn't it good to sleep? I finally managed to sleep in...... It's been a long time since I've slept in. Yuriko said in a daze.

She rolled over lazily, habitually pinning his arm under her neck, and wanted to lie down a little longer.

"How does sleeping compare to doing experiments?" Yu Yifeng quipped.

"It doesn't feel the same."

"You never know what the next experiment will turn out to be...... If it is as expected, the experiment is of course successful and it feels very good. If it doesn't match expectations...... Maybe something new will be discovered and it will feel even better! ”

In just like that, the two of them had gradually woken up, and they no longer had any sleepiness.

“…… I'm so awake that I don't even want to sleep since I installed my brain chip......"

"It indirectly changes our habits." Yuriko smiled and brushed her hair.

As brain chips have improved from generation to generation, so have become more and more functional, and some inherent defects in the human brain have gradually disappeared.

Brain diseases such as epilepsy and insomnia no longer exist.

At the same time, people's intelligence has greatly improved, they are more rational, and they are able to control their emotions. At the same time, it can also enter deep sleep more quickly and get better rest.

"It's boring to sleep, how about we go out?" Yu Yifeng proposed.

"Okay, where are you going? You can't go to an amusement park, can you? Yuriko smiled and was in a very good mood...... This is the first time for the first time.

"How about a barbecue in the forest?"

"A barbecue for two? Boring. ”

Indeed, this kind of thing is fun when there are more people, and it is better to go to a restaurant for two people to have a barbecue.

Yu Yifeng frowned, and suddenly remembered something he heard a few days ago. "I've heard that a couple of lads have remodeled the Gold Coast, so let's go check it out."

"That dead sea? I've seen it, it's not very good......"

"Yes, it's said to have gotten a lot prettier."

"Okay, then go to the beach and soak up the sun."

Now that they had made up their minds, the two got up and took action.

Yuriko rubbed between the underwear for half an hour, and finally chose a beautiful white shirt, and deliberately combed her hair, which looked very beautiful. Of course, people of this era, regardless of age, are very beautiful.
