Time flies, thousands of years, 10,000 years, 100,000 years have passed.

The Green Star civilization has long since left this starry sky and gone to other places to plague it. At this stage, human beings walked out of the African savannah and gradually entered the Paleolithic Age.

As a result, on the planet Karina, another intelligent civilization was born.

The second age of intelligent creatures, hemispheric 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 beings one after another. Just like the tiny earth, Homo sapiens, that is, humans, is a relatively clear intelligent species.

But humans are not the only intelligent species.

Just like the Thai macaque, West African chimpanzee, Brazilian black-banded capuchin monkey and white-faced capuchin monkey, these species may also have passed into the Paleolithic Age, and they have a certain probability of evolving into intelligent species in the distant future, without human intervention.

This is no joke.

These clever monkeys will use stones as their tools, smashing nuts, digging in dirt, and holding things. That is, they have a certain ability to learn.

The use of stone tools is not innate, but learned through social factors. Give them more time, and the monkeys may not be able to learn more.

These monkeys have a language of their own, and the last step away from sapient beings is simply the use of fire.

If they are given enough time and a certain opportunity, hundreds of thousands of years later, the monkeys may be able to develop a real civilization.

But if humanity on Earth doesn't perish, the monkeys will never have a chance.

The reason is not that human beings are afraid of the emergence of another intelligent life and do not allow them to develop. But...... The monkey's ecological environment is completely controlled by humans, and they can only live in the same environment forever, and there is no way to survive outside their habitat.

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

The banal theory of the universe is universal, and it applies to interstellar civilizations, as well as to the most primitive monkey natives. Comfort and contentment are the factors that most likely lead to mediocrity.

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

Closer to home, the Second Age sapient creatures, the Hemispheres, appeared in this world, and they are close relatives of the Polyspheres. Now that the polyspheres are extinct, the hemispherical people have gone through the Stone Age for more than 100,000 years and are very fortunate to be on the throne. However, due to the age, they did not know that there was once a wise civilization of the First Age.

With the development of the times, the hemispheres also gave birth to a brilliant civilization, created their own language and writing, and established feudal dynasties.

But they face a very big dilemma – they don't have fossil fuels.

There is no oil, no coal, no gas, not even combustible ice under the ocean.

No, nothing.

These fossil fuels were exhausted by the multispheres of the First Age, and it was impossible to produce a drop of oil or a single drop of coal in a mere hundred thousand years.

Without enough fossil fuels, the hemispheres are miserable, and no matter how smart they are, there is no way to enter the industrial age, and the cost of energy from plant combustion alone 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 amount of growth each year is fixed, and it is impossible to take it like coal.

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

Hemispherics, who have not been able to enter the industrial age for a long time, have slowly become a mediocre civilization......

They remained in the traditional handicraft era, where hemispheres were able to smelt some metals from charcoal, but the cost was too high, and it was very difficult to make steel on a large scale.

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

This slow era lasted for at least 50,000 years, and much of the historical material has been lost, which is too long compared to human contemporaries.

But after a long period of exploration, production experience can be accumulated, and in the long process of division and merger, the idle upper class began to prefer some spiritual enjoyment, mathematics, art, and ...... Archaeological culture.

Archaeological culture, the biggest variable of Karina.

In fact, hemispheres are often able to dig up strange things in their daily lives, which is the so-called "ancestral heritage".

Like some rusty steel bar, concrete bricks and so on, and some very strange things. The confused hemispheres have always thought that they are the traces of life left by their ancestors, and will hide these things.

Karina is an oxygen-rich planet, and over time, oxygen has corrupted most of the First Age legacy, so the hemispheres who have stayed in the feudal era for a long time have never regarded them as treasures.

Ordinary people picked up interesting garbage, and the metal content was directly smelted, and the ones that seemed to have some value were sold to the dealers who collected antiques.

Merchants then sold collectible antiques to the nobles.

The aristocracy compared each other's collection of antiques and suddenly discovered that modern arts and crafts were not as refined as those of ancient times, a fact that puzzled them.

The development of handicrafts to the present, how can it not be compared to ancient times? What kind of life in ancient times, they knew.

In particular, there has been no way to decipher the various ancestral scripts, which are very numerous and completely different from those they currently use. Under curiosity, some idle nobles began to organize people to decipher these words.

It wasn't until an archaeologist preliminarily deciphered the language of the "ultra-ancient civilization" that the entire upper class suddenly realized!

"It's not our ancestor!"

"Rather...... There was a super-ancient civilization in the world, and they were far more developed than us! ”

"What is this? Magic? ”

"The place where we live is called the planet, and the planet is round! There's a universe out there! ”

The discovery of this fact stunned the hemispheres.

Immediately after, the news spread throughout the kingdom, and the major nobles began to frantically loot antiques and collect those valuable things.

A massive archaeological operation has been carried out on Karina, where fanatical hemispheres have almost dug the entire planet into the ground, and in this high-oxygen environment, only a few shelters buried underground can be saved.

Just like digging an ancient tomb, every time one is excavated, it is a big catch. Everywhere you can hear the news that so-and-so dug up a treasure and became rich overnight

Although the heritage of the entire planet has been lost a lot, it adds up to a lot. These crazy nobles even went overseas to buy on a large scale, and as a result, they launched wars of aggression again and again to rob other countries of their wealth.

But it is precisely these archaeological data that provide a solid foundation for future development.
