Time flies, thousands of years, ten thousand years, and hundreds of thousands of years have passed.

The Green Star civilization had long left this starry sky and ran to other places to cause disaster. At this stage, humans walked out of the African prairie and gradually entered the Paleolithic Age.

As a result, another intelligent civilization was born on Kalina Star.

In the second era, intelligent creatures, hemisphere civilization was born!

When Zhang Yuan saw this line of text, he couldn't help but raise his eyebrows.

It is not uncommon for a planet suitable for the evolution of life to develop two different intelligent creatures one after another. Just like the small earth, Homo sapiens, that is, humans, is a relatively clear intelligent species.

But humans are not the only intelligent species.

Just like Thai macaques, West African chimpanzees, Brazilian black belt capuchin monkeys and white-faced capuchin monkeys, these species may have been overly in the Paleolithic Age. If there is no human interference in the distant future, there is a certain probability that they will evolve into smart species.

This is no joke.

These smart monkeys will use stones as their tools to smash nuts, dig dig soil, and store things. That is, they have a certain learning ability.

Using stone tools is not innate, but learned through social factors the day after tomorrow. Giving them more time may not necessarily lead to more things.

These monkeys also have their own language, and the last step away from the intelligent creatures is just using flames.

If they are given enough time and certain opportunities, monkeys may be able to develop a true civilization in hundreds of thousands of years.

However, if humans on Earth do not perish, monkeys will never have a chance.

The reason is not that humans are afraid of the emergence of another intelligent life and will not allow them to develop. Instead... the ecological environment of monkeys is completely controlled by humans. They can only live in the same environment forever and cannot survive outside their habitat.

In the case of extremely stable environment, no mobility means that there are no variables. As long as monkeys maintain their current lifestyle, they can live well. In this way, the society composed of monkeys will inevitably be inverted and society will stop progressing.

The theory of mediocrity in the universe is universal, applicable to interstellar civilizations, and also to the most primitive monkey natives. Comfort and satisfaction are the factors that are most likely to lead to mediocrity.

Therefore, the development of civilization requires internal factors and changes in the external environment. If there is no change, you must find changes by yourself. This is also the main reason why the new human fleet is constantly wandering in the universe.

Back to the topic, the second era of intelligent biological hemispheres appeared in this world. They were close relatives of the multi-ball people. Now the multi-ball people are extinct. The hemispheres have gone through more than 100,000 years of Stone Age and are very lucky to have risen. However, because the times are still the same, they do not know that there was a first era of intelligent civilization.

With the development of the times, people in the hemisphere have also born a brilliant civilization, created their own language and characters, and established feudal dynasties.

But they face a very big dilemma without fossil fuels.

There is no oil, coal, natural gas, and even combustible ice under the ocean.

No, nothing.

These fossil fuels were consumed by the multi-ball players in the First Age. In just tens of thousands of years, it was impossible for any drop of oil or coal to be born.

If there is not enough fossil fuel, hemispheres will be miserable. No matter how smart they are, they will not be able to enter the industrial age. The cost of relying solely on plant combustion to provide energy is too high. The production of charcoal requires a large number of people to mine, and the productivity is limited. After all, the growth of plants depends on photosynthesis, and the total growth of each year is fixed, and it is impossible to obtain it like coal.

Under such conditions, the accumulation of capital is too slow, and technology will naturally not be able to develop.

Hemispheres who have not been able to enter the industrial age for a long time have gradually become a mediocre civilization...

They have been staying in the traditional handicraft era. Hemispheres were able to use charcoal to smel some metals, but due to the high cost, it was very difficult to further make large-scale steelmaking.

Large steelmaking is one of the very important conditions for industrialization.

This slow era lasted for at least 50,000 years, and many historical data were lost. Compared with the human contemporaries, it seems too long.

But long exploration can eventually accumulate production experience. In the long-term separation and reunion, the idle upper class began to prefer some spiritual enjoyment, mathematics, art, and... archaeological culture.

Archaeological culture, the biggest variable of Kalina Star.

In fact, in histograms, people in his daily life, can often find strange things, namely the so-called "ancestor legacy".

Such as rusty steel bars, concrete bricks, and some very strange things. The confused hemisphere people always thought that they were traces of life left by their ancestors and would store these things.

Kalina is an oxygen-rich planet. Over the long period of time, oxygen corrodes most of the first era heritage, so the hemispheres who have been in the feudal era for a long time have never regarded them as treasures.

The common people pick up interesting garbage, and they will directly smel them with metal components. Those that look a little valuable will be sold to those merchants who collect antiques.

The merchants then sold antiques of collection value to the great nobles.

The nobles compared the antiques collected by each other and suddenly discovered that modern art and crafts were not as exquisite as those in ancient times. This fact made them puzzled.

How come handicrafts have developed to this day, but they are still not as good as ancient times? They know what kind of life they were like in ancient times.

Especially the various ancestral texts have never been able to decipher them. The number of these texts is very large, completely different from what they are currently using. Under curiosity, some idle nobles began to organize their hands to decipher these texts.

It was not until an archaeological expert initially deciphered the language of "super ancient civilization" that the entire upper class suddenly realized it!

"It's not our ancestor!"

"But... there is a super ancient civilization in the world, and they are far more developed than us!"

"What is this? Magic?"

"The place where we live is called a planet. The planet is round! There is also a universe outside!"

The discovery of this fact shocked the people of the hemisphere.

Immediately afterwards, the news spread throughout the kingdom, and the great nobles began to snatch antiques and collect valuable things.

A grand archaeological operation appeared on Kalina. The fanatical hemispheres dug almost three feet into the entire planet. In this high oxygen environment, only some refuges buried under the ground can be preserved.

Just like digging an ancient tomb, every time one is excavated, it is a big harvest. You can hear the news that XXX has dug up treasures and become rich overnight.

Although the legacy of the entire planet has been lost a lot, it has really been quite a lot. These crazy nobles even went overseas to acquire them, and thus launched wars of aggression to seize the wealth of other countries.

But it is these archaeological materials that provide a solid foundation for future great development.
