As for how to solve the problem of underground caves, experts have been thinking for a long time and there is no particularly good solution.

At present, even if there are mines on the surface, people do not dare to dig because of the large caves underground. If the ground is dug up, it will be lost along with the entire base, wouldn't it be a loss of people and money?

With the current technology of human beings, it can actually fight against nature, and it can be done while mining and tamping the foundation, but the economic cost of doing so is too great and it is not very cost-effective.

Therefore, these scholars generally believe that it is better to go directly to the Arctic to mine......

There are no volcanoes, no geothermal heat, and it is cold all year round, so there won't be so many underground cavities, right?

After rigorous arguments by biologists, it is now possible to determine that large underground cavities have been corroded by black worms. Without geothermal energy, it is unlikely that there will be black worms underground, and it is unlikely that there will be cavities.

Listening to the discussion of the experts, Yu Yifeng kept thinking about it in his heart.

Changing bases is not a big deal...... Thinking about it economically, at least, it's much simpler than laying a solid foundation. The hollows underneath are almost endless, so there's no need to force them.

There is no shortage of equipment for human beings, and there are still a large number of flight bases and excavation machines on the Noah, which are not officially used. The new human civilization is only short of manpower, and if the base is rebuilt, the engineers here will be transferred to the Arctic region in large numbers.

Of course, according to the discussion of these experts, there are advantages and disadvantages to the new base moving to the Arctic region of the Knicks.

The temperature there is minus 200 degrees, the temperature is too low, the biological activity is weak, and the microorganisms are scarce...... Therefore, the task of biological control in the Arctic has been reduced a lot, and the probability of people getting sick will be greatly reduced.

And the combustible ice resources of the Arctic are relatively easy to mine, and there will be no shortage of energy from now on!

But then again, because the temperature is too low, all kinds of machines will be severely tested, and the mechanical failure rate will be greatly increased......

Many materials should be replaced, especially cement materials must be replaced with special cold-resistant cement to adapt to low temperatures of more than minus 200 degrees Celsius.

In short, these problems can be big or small, not that they can't be solved!

If you can solve a problem, it's not a big problem!

At present, the biggest problem plaguing the new human civilization is still the shortage of manpower! Population is the most critical factor restricting industrial development, no matter how intelligent the human machine is, it is not a real artificial intelligence, and it must be controlled by humans in the background.

That's it...... People must be encouraged to have a second or even a third, a fourth, or a fifth child! In short, the more the merrier!

We must vigorously strengthen social and public services, strengthen the education system of the entire civilization, and encourage people to have more children!

"Fortunately, with stem cell reactivation reagents, people are still passionate even if they are in their thirties, and the birth rate has increased a lot...... "Yu Yifeng thought.

"It would be nice if there were 200,000 high-quality people!"

"If you can't do it, you will close all the factories that produce ***! If you are pregnant, you will be born! "In the midst of such cranky thoughts, all the formal discussions ended.

"Then it was decided that we will build a new main base in the Arctic region, and the factories that have been built here do not need to be demolished on a large scale, so let's treat them as sub-bases!"

Yu Yifeng finally set all the agendas, and then tried to steer the conversation to the indigenous people.

He changed his words and said casually, "Oh, by the way, I have another very important thing to say here. Look at the video file I just sent. It was given to me by a soldier who had disappeared, so you can take a look at it first. ”

He clicked on the video, curious to see how everyone would react. He should have been the first to know about it besides the eight soldiers.

The others were still sitting silently until now, and some were even distracted thinking about what had just been discussed, and they only thought that Yi Feng wanted to show them some industrial videos.

Immediately, the video began to play, and from the first image, everyone was stunned, even a few people who had just been distracted were stunned, just like Yu Yifeng's expression at that time.

Some people have their mouths wide open and haven't closed for a long time, and a few have round eyes that don't blink!

The video begins with the lizardmen cutting bugs, then negotiating with the soldiers, and then returning to their large villages......

The lizardmen looked puzzled when they saw the liquid nitrogen that people took out and frozen. One of the curious lizards touched the ice on the surface of the power armor with its claws. After being stimulated, the paws immediately retracted, then touched again, and retracted again.

They wondered why the water was suddenly frozen.

Why are these "scales" so hard?

Sure enough, he is worthy of being the "messenger of the gods"!

However, they are also very smart, and after some negotiation with the soldiers, they seem to understand something, and take out some strange herbs to coat the power armor.

In this way, the smell of the special herb is avoided by black insects, and there is no need to spray liquid nitrogen on the surface.

Wu Hao and the others also stupidly followed over, as if they were not afraid of danger...... Or rather, they think they've taken the initiative.

From a distance, this indigenous village is divided into earthen bags and caves, and there are about a few thousand large and small earthen bags in it, and the total population of lizard natives is estimated to be tens of thousands, all stationed in the crater!

Yes, the crater!

The whole video was just filmed from a distance and did not come closer.

But everyone here saw a thick layer of magma at a depth of a few hundred meters at the bottom! Their glow illuminates the area slightly. It's probably the brightest place underground.

However, the magma tumbling ground is not violent, perhaps because the area has been silent for too long without geological activity.

Wu Hao, these fools, followed the lizard natives unguardedly, and then walked to the crater area inexplicably, maybe their hearts were also broken......

A large number of black bugs crawled on the volcanic rock wall, this time it was really massive, many times more than they had encountered before, if the previous time was a desert, this time ...... It's a boundless ocean!

However, these bugs appear to be very docile when they are given enough heat. They absorb heat, survive, and reproduce on magma walls. Of course, over hundreds of millions of years of evolution, they have always found a suitable place to keep themselves from being ignited by the heat.

In this heat, the surface temperature is already as high as 30-40 degrees Celsius, and if you get closer, it may rise to 60 to 70 degrees!

The villages of the indigenous people are probably in the outlying areas around 30-40 degrees. Perhaps in this high-heat environment, even if you don't spray herbs and ice, the heat-generating power armor has no appeal.

This crater area is already the core of the underground ecosystem and the largest cave. Because magma provides a lot of heat, it is infested with all kinds of large creatures, as well as a large number of plants, fungi, and so on.

They're all geothermal creatures! Just by absorbing heat energy, it can synthesize organic matter, which is unique to the life of the Nix!

The rock walls and stone pillars around the crater have been corroded by acid and are crystal clear, and can even reflect the light of magma! Also thanks to the biological acids, these stones leave only the strongest mixture of substances, which are really hard and terrible.

One of the team members also sawed one of the pillars with a chainsaw out of curiosity, leaving only a shallow mark.

To know...... The material of the chainsaw is a super alloy Z! It is enough to see the hardness of these acid mixtures after condensation, so this huge cavern has not collapsed.

Spectacular, really spectacular!

Yu Yifeng was amazed in his heart while watching, although he had watched this video several times, he was still shocked every time he watched it.

Such an underground landscape is beyond human imagination......

The venue was very calm for a while, whether it was the Noah conference room or the Knicks Star conference room, even the sound of breathing was suppressed.

People are digesting the information they receive, as if they were watching a movie.

But everyone knows that Yu Yifeng can't be idle and show them a movie......

After the video, everyone seemed to be down and didn't say a word.

"It's ......"

After a long time, one of the biologist's eyes widened and let out the first exclamation in the conference room: "Underground caves? Indigenous civilizations? Could it have been found in a large underground cavern?! ”

"It can't be computer-generated, right? Mr. Yu, where did the video come from? ”

"Really? It can't be a movie special effect, right? ”

Everyone asked anxiously, and their first feeling was: this video is fake!

But judging from the rough shooting techniques and realistic scenes, it shouldn't look like a deliberate fake, and there is no need to fake to entertain everyone.

Even Xu Yunjin's eyes lit up and roared: "Isn't this Wu Hao?" Lao Tzu's soldiers, what's going on! ”

Hearing Xu Yunjin's anxious roar, everyone knew that the probability of the truth was extremely high! Their eyes are getting brighter and brighter, as if incredible!

A sprawling underground cavern, and even an indigenous civilization in it!

What does it mean to be indigenous?

Everyone in the conference room suddenly lost their breath with excitement and panted like a cow.

But they really can't figure out what to do with these natives for a while.

"! Catch them and go to mining! ”

Dr. Rimbaud screamed excitedly and jumped from his position. In fact, his field of study had little to do with indigenous people, and he was just shouting out curiously.

Suddenly, everyone recovered from the shock and turned to laughter.

Mining is such a thing...... These indigenous lizards have thin arms and legs, and it is estimated that the combined output of the whole village will not exceed that of a heavy excavator.

But after such a smile, everyone was silent and thoughtful.

What does it mean that intelligent civilization has been encountered so simply?

They are not simple-minded soldiers, but think about something deeper.

In this universe, civilization can't be a rotten street, right?

Perhaps, it is really possible......

Is humanity so lucky? If civilization is scarce, it can be encountered casually?

Life is rotten streets, and civilization may also be rotten streets, so it can be explained: just a fairly good planet meets civilization......

Whether civilization is rare or not is not considered for the time being, then...... What should be done with these indigenous lizards?

This is the primary issue before us.

Human beings are not virgins, nor butchers, and there is no good or bad for no reason in the world. From the perspective of civilization, we must think about problems from the perspective of "interests."

What can indigenous civilization bring to mankind? What's in slight? What can they do to help humans? Is it a threat?

These are all questions worth pondering......
