The result...... The population is seriously underpopulated!

For now, population has become the biggest obstacle!

For the almost unsolvable problem of population, Yu Yifeng really had a headache, and he discussed with various experts, but in fact, he couldn't discuss the results. Ｘ

The development of indigenous lizards is important, the mining of the Arctic region is important, and the exploration of the ruins of civilization is also needed. Where did so many people come from?

Now more than nine years have passed since the Earth exploded, and the total population of Noah has reached more than 80,000 people, including nearly 30,000 children!

With the new government constantly encouraging childbearing and constantly improving social and public welfare, many families have finally given birth to a second or even a third or fourth child! The growth rate of the population has almost reached its limit.

Raising children requires energy, and these families refuse to have children anymore no matter how much they encourage them. It is impossible for a man to give birth to one every year like a pig.

These children, the oldest of whom are only eight years old, are still in a particularly troubled stage, and the large number of babies brings a heavy burden of social support.

Even today, when robots are fully popularized, it is impossible for robots to do all the work, and many children must be raised by humans.

So, these kids are dragging a large number of people. If there are too many people who have been dispatched, the Noah society will not be able to run smoothly.

After all, the Noah is the real home of mankind, and its stability must be ensured, so that the people in front of the desert can work with peace of mind.

Perhaps one of the pioneers is the father or mother of two or three children, who are here to fight for a better future for the next generation.

Therefore, the Noah must not have an accident, not even a little safety hazard.

Yu Yifeng calculated carefully, and what he could really deploy at will in his hands was ...... Eight thousand, at most ten thousand will be the sky!

Really couldn't have more!

More than 10,000 is beyond the capacity of the Noah!

You can't all the adults come down to clear the wasteland, and the Noah has a bunch of children, right?

Yu Yifeng sighed, he really missed that time when there were no children...... The population of 50,000 is all bachelors, who can be dispatched at will, and one person is fed, and the whole family does not worry.

Now that the total population is increasing, the available population is decreasing, and there is really no way.

Such a period of oral pain, patience will always pass. This time may take one or two decades, and then the population structure will gradually become reasonable, and everyone will be liberated......

In this way, even in the case of lack of population and serious lack of motivation, Yu Yifeng still gritted his teeth and consulted a large number of experts, held a large number of meetings, and formulated the final plan......

They took relatively unimportant posts and put all the available population to good use!

The new human civilization began the next era of great excavation......

Mining, and digging cities!

With the help of a large number of machines, in just one month, the fanatical humans cleared the underground city buried beneath the dirt.

People can finally happily pick up trash.

It's a real city, not a primitive village of indigenous lizards. It has a variety of buildings and a large amount of mechanical residue.

In the course of the excavations, the remains of individuals of this civilization were even found, that is, ...... Some fossilized bones of creatures!

Covering an area of about 7.6 square kilometers, the city does not look very large, but it was built on the extinct volcano below, so to speak, on the crater.

Unlike human cities, only a small part of it is a surface structure, and most of it is buried deep underground to withstand the cold weather of Nix.

The Forbidden Land in the Lizard's Mouth, where the nuclear power plant originally existed, was located on the surface of the city at the very edge of the city and supplied electricity to the original city.

After the nuclear power plant was destroyed by the war, the nuclear waste inside was leaked significantly, so it has been radiated for so long......

The city is a three-dimensional structure, with a depth of about a kilometer at the bottom, and at the bottom, there are all kinds of plumbing and mechanical equipment.

Scientists speculate that the small city could use the heat of the entire volcano to power the city through these devices.

Of course, this volcano was once dormant or extinct, and the probability of an eruption is not very high. If the eruption is unlucky, these residents have to flee collectively through emergency equipment, and the eruption has some signs that can bring a certain amount of time to escape.

However, most of the houses inside have collapsed, and the original equipment has been damaged, so it is impossible to see the original pomp.

Many things are fused with mud and stones, and it is quite difficult to distinguish them. In particular, the metal in the open air is basically impossible to survive until now under the action of microorganisms and oxygen.

"Based on geological analysis, we believe that the city was built in ...... Eleven million years ago! The error will not exceed two million years. Therefore, the time from the extinction of the Knicks civilization should also be that era. ”

A geologist who came up with a final report from his computer said with some shock as he looked at the results. This time is too far away for humanity to prove that this unknown civilization has fallen into an endless period of time.

And what he was holding in his hand was a biological fossil, a fossilized skull of the Knicks!

It is also on the basis of these fossils that one can calculate the final conclusion.

Hearing this number, Yu Yifeng's heart was also shocked, and he had to sigh at the vicissitudes of the universe...... Eleven million years!

Eleven million years is simply unimaginable time for human beings, and on the scale of the universe, it is also a long time......

Eleven million years have passed since the fall of the "Knicks civilization", which is too long. It is only today that the city has been rediscovered thanks to human excavations.

For 11 million years, nuclear contamination still exists...... It is enough to prove the pollution of nuclear waste!

I have to mention that this extinct unknown civilization is called the "Knicks Civilization" by humans!

They are the real top of the food chain for Nix.

The indigenous lizards in the back are called the "indigenous lizard civilization". In this way, the two can be easily distinguished.

"Judging from the excavated skull fossils, the Nix civilization and the indigenous lizard civilization underneath the ground are actually two different species." The geologist explained while leading Yu Yifeng through the various items excavated.

Individuals of the Knicks civilization also look very reptilian creatures, but they are larger and stronger than the indigenous lizards, they have six legs, an average height of 1.6 meters, and a head the size of a human. They have a slender tail two or three meters long on the back, which seems to have other functions.

And judging from the fossils, their body structure and the extracted DNA are completely different from those of indigenous lizards.

So, these two species are actually different.

The indigenous lizard is likely to be a native species that evolved after the extinction of the Nix civilization...... On a planet, two different intelligent civilizations have appeared before and after!

This is a bit unbelievable!

Especially...... The living environment of this planet is not very good, and the creatures here are just barely able to survive compared to the earth.

But...... The two intelligent civilizations before and after, this is one thing that makes many smart people extremely afraid, which shows that it ...... Wisdom is not uncommon in this universe!

Even, civilization is not uncommon!

Some people even speculate that before human civilization, there were also super-ancient civilizations on the earth. And then they went extinct before there were humans?

At least, there are indeed traces of ancient civilizations on the previous earth...... All kinds of unsolved mysteries.

The universe is really cruel, since civilization is not rare...... So why are so many civilizations trapped on their own planets? Why is it so difficult to become an interstellar civilization?

It can only be stated ......

There is a great probability that human beings will face the great filter of life that has not yet been crossed, and it is almost insurmountable!

Even an optimist like Dr. Rimbaud has to admit that the probability of the Great Filter of Life being in front of humanity is extremely high......

However, what this life filter is, humans still don't know, maybe when digging the ruins of the Nix civilization, some clues can be found......

Humanity is still optimistic for the time being, and it is impossible to be intimidated by something that has not yet appeared...... r
