It's reasonable for me to have a two-way foil for a second-level civilization, right?

"Although it is very difficult to obtain, its reserves are extremely rich."

"When the first batch of mining ships made of star gold-carbyne composite materials come out, the production capacity of star gold will increase rapidly."

"At that time, the asteroid-level [Earth] can be put on the construction schedule!"

Lu Yongchang nodded, and suddenly his eyes moved, as if he remembered something.

"By the way, Zero, how is Hope?"

"He didn't seem to be in a good mood when he came out of the ice giant."

"I heard from the psychiatrist that it was because of the environmental problems in the ice giant that he had an emotional resonance with the giant fish?"

"Is that the case?"

Cao Liang who was on the side was stunned when he heard it.

And this stuff? !

In the next second, Zero's avatar appeared beside Lu Yongchang.

Zero nodded, affirming Lu Yongchang's statement: "The diagnosis is indeed so."

"However, Hope has now largely recovered."

"Oh?" Lu Yongchang had a relaxed smile on his face, "How did he recover?"

"He applied for a second exploration mission." Zero's electronically synthesized voice echoed faintly in the laboratory, "In his spare time for mineral exploration, he acted as a breeder for giant fish."

The voice fell, and the picture in the holographic projection changed rapidly.

In the picture, the [Poseidon II] exploration ship is waving its mechanical arm, throwing sealing devices full of cesium chloride and rubidium chloride one after another to the giant fish school in the distance.

And the giant fish, after "eating and drinking enough", led the exploration ship to drill into the depths of the liquid ammonia ocean.

"The giant fish now seem to know the difference between the survey ship and them."

"At the same time, under the leadership of the giant fish group, Hope and Hancent successfully found the second star gold mine."

"The reserves of star gold deposits inside ice giants are far more than we imagined."

With Zero's voice, the holographic screen switched to the cockpit.

Hope's face was full of smiles, and beside him, Hansent had an expression of lovelessness.

Lu Yongchang looked at the picture in the holographic projection and laughed dumbly: "Coexist?"

"It's a good choice."

ps: Thank you Jiu Liyi for your certification!No, I can’t add it anymore... Wait for two days and make it up...

Chapter 495 The Kiss of Death

Five years passed by.

In the past five years, the environmental transformation project of Dawn Star has never stopped and has been going on silently.

Compared with the beginning, the Dawn Star at this time already has a bit of the appearance of the earth.

But only a little.

It still takes a lot of time for human beings to really get out of the closed city and start living under the blue sky and white clouds.

At the same time, human enhancement projects are also advancing.

With all members of the Academy of Sciences and the Parliament leading by example, the speed of human enhancement projects has increased significantly.

Although there are still some stubborn people who don’t believe in the so-called genetic modification technology, they see their relatives and friends, and even strangers on the street who have never met before, take off their exoskeleton armor one by one, and shut down the computer that runs every night. The family version of the medical cabin breathes a breath of freedom...

These old stubborns couldn't hold back their inner turmoil, and joined the human body strengthening project.

From the looks of it, everything seems to be thriving.

But after five years of fermentation, a problem has become more and more serious.

……

"According to the latest calculation results, the People's Federation's comprehensive fertility curve will intersect the comprehensive mortality curve in 300 years."

Zero's voice echoed in the office.

In the holographic projection, it is a meandering curve.

The ever-sliding curve above represents the comprehensive fertility rate of human civilization.

And the slowly rising line below is the comprehensive mortality rate curve of human civilization.

Compared with the calculation results a few years ago, the time when the two curves intersect has been shortened by nearly 200 years.

Sitting on a chair in the office, Lu Yongchang sighed softly as he watched the two continuously extending and finally intersecting curves in the holographic projection.

As the chart shows.

With the passage of time, the older generation from the earth and even from Proxima b continued to die out, while the number of newborns decreased year by year, eventually leading to the "kiss of death" between the comprehensive birth rate curve and the comprehensive death rate curve ".

Especially the last five years.

The number of newborns is falling off a cliff every year!

For an interstellar civilization, the intersection of these two curves means that the civilization is declining and eventually dying.

Like the human civilization of Proxima Centauri, the People's Federation still encountered this fatal problem after all.

However, there are still some differences between the Human Federation and the human civilization of Proxima Centauri.

Proxima Centauri has a population crisis caused by a small population base and a shortage of living resources.

The People's Union is exactly the opposite.

The population base is huge, and there are still billions of people in the [Home Ship] that have not been awakened and are still in a state of hibernation.

Survival resources are also abundant.

After entering the third-level civilization, especially after another breakthrough in computer technology, Zero's computing power has been greatly improved, and the productivity level of human civilization has also been greatly improved.

After 100 years, the environmental transformation of Dawn Star will be declared a success.

Human beings will also walk out of the small closed cities, and the billions of people in the hibernation cabins will also be awakened one by one.

But this still does not solve the problem of declining comprehensive fertility rate.

the reason is simple.

Compared with the era of Earth, or the era of Proxima Centauri b, the birth cost on Dawn Star is too high.

Whether it's human enhancement programs or life-extending technologies, it's all for fully developed adults.

Therefore, before adulthood, human beings are still as weak as the earth era.

This also leads to a problem.

On Dawn Star, which is in an environment with a gravity of 1.9g, fertility has become a huge problem.

A newborn baby will definitely not be able to withstand the 1.9g of gravity on Dawn Star.

Of course, the People's Union Academy of Sciences has also made corresponding solutions.

Dawn star synchronous orbit large space station.

The ring-shaped space station can rely on rotation to generate an equivalent gravity of 1g. To a certain extent, it can simulate the earth's environment to a great extent-this is extremely friendly to the growth and development of infants and young children.

Only when they reach adulthood, these new generations born on the space station can accept the transformation of human body enhancement and life extension technology.

The growth and development time varies from person to person, and the average time is about 18-20 years.

For the safety of the new generation, the time for the two transformations of human body strengthening and life extension is set at 25 years old.

That is, the time when the human brain fully develops and matures.

At the same time, this is also the time for the new generation of human beings to perform the "adult ceremony".

Only after completing the [Ceremony of Adulthood] and undergoing the two transformations of body strengthening and life extension, can they be new humans in the true sense.

For newborns, there is nothing wrong with this provision.

But for parents, this regulation is the culprit that has caused a cliff-like decline in fertility!

Under the traditional parenting model, it is impossible for both parents to abandon their children and live alone on the surface of Dawn Star.

This creates an embarrassing scene.

It takes at least 20 years for both parents to give birth to a child.

For new humans with an average lifespan of 1000 years, 20 years is actually nothing.

What's more, the parliament has various comprehensive safeguards for this long period of childbearing.

Even, you can use maternity as an excuse to achieve up to 20 years of paid leave.

The words say so.

But if it really falls on me, it's another scene.

Even if today's human technology can go back and forth between the synchronous orbit and the ground at will, the hidden cost of up to 20 years is unbearable for ordinary people.

then……

During these five years.

There are few people in the three completed synchronous orbital space stations.

The number of newborns is also decreasing year by year.

In an attempt to save the declining overall birth rate, the Academy of Sciences launched a medical pod for infants and young children two years ago.

After the newborns are born, these infants can enter a shallow hibernation state in this specialized medical pod.

The so-called shallow hibernation state is very similar to the deep sleep state, and the metabolism, growth and development of the human body will not stop.

in other words.

Infants and toddlers can "sleep" in this special medical pod until they reach adulthood.

Then complete the [Adult Ceremony] and start your new life.

This greatly reduces the time cost of raising the next generation for both parents, but it creates another serious problem.

Educational issues of the new generation.

No one wants to teach a 25-year-old able-bodied adult how to toilet, eat, and walk.

What's more, the learning of language skills is often carried out in infants and young children.

then……

As soon as the alternative program was born, it declared bankruptcy.

This has stabbed the already poor fertility rate and made its decline faster.

Chapter 496 Begins

"Could it be...do you really want to choose the social public support system?"

Lu Yongchang's eyes were uncertain, and he frowned and muttered to himself.

The tragedy of human civilization in Proxima Centauri is still vivid.

In the past few years, the human civilization of Proxima Centauri, with the help of information from the People's Union Academy of Sciences, has finally managed to gain a foothold—the public breeding system has been activated again.

Due to the lack of resources, even with the adoption of the social support system, the comprehensive fertility rate of Proxima human civilization is only comparable to the death rate.

In simple words.

The current human civilization of Proxima Centauri has completely lost all its development potential without the help of external forces.

After the star eater absorbed a lot of energy, the host star of Proxima Centauri has reached its twilight years.

This resource-poor star system now looks even more bleak.

As for the human civilization of Proxima Centauri, after experiencing such wars and wasting so many resources, it naturally lost hope of leaving Proxima Centauri.

Now, all their efforts are nothing but pointless struggles on the verge of the extinction of civilization.

It is precisely knowing this that Lu Yongchang is so entangled.

The social public support system is an extremely sharp double-edged sword.

The human civilization of the Proxima Centauri has already traveled a bumpy road for the Federation of Human Beings at the cost of blood.
