Time flies. Thousands, thousands, and hundreds of thousands of years have passed.

The green star civilization has long left this starry sky and gone to other places to harm. At this stage, mankind walked out of the African prairie and gradually entered the Paleolithic age.

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

Intelligent creatures in the second era, hemispheric civilization was born!

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

It is not surprising that a planet suitable for life evolution has developed two different intelligent creatures. Like the small earth, Homo sapiens, that is, human beings, 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 also transition to the Paleolithic age. In the distant future, if there is no human intervention, they have a certain probability to evolve into intelligent species.

This is no joke.

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

Using stone tools is not born, but learned through social factors. Given more time, monkeys may not be able to learn more.

These monkeys also have their own language, and the last step from intelligent creatures is only to use fire.

Given enough time and opportunities, monkeys may be able to develop a real civilization in hundreds of thousands of years.

However, if human beings on earth do not perish, monkeys will never have a chance.

The reason is not that human beings are afraid of the emergence of another intelligent life and don't let them develop. But... The ecological environment of monkeys is completely controlled by humans. They can only live in the same environment forever and can't live outside their habitat.

When the environment is extremely stable, there is no mobility, which means that there are no variables. Monkeys can live well as long as they maintain their current lifestyle. In this way, the society composed of monkeys will inevitably be involuted and the society will stop making progress.

The mediocre theory of the universe is universal, applicable to interstellar civilization and the most primitive monkey aborigines. Comfort and satisfaction are the most likely factors to lead to mediocrity.

Therefore, the development of civilization needs both internal causes and changes in the external environment. If there is no change, we must find the change ourselves. This is also the main reason why the new human fleet keeps wandering in the universe.

To get back to business, the intelligent biological hemispheres of the second era appeared in this world. They are close relatives of multiglobes. Now the multi ball man is extinct. After more than 100000 years of the stone age, the hemispheric man is very lucky to be on the top. However, because the age is 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 also gave birth to a splendid civilization, created their own language and established feudal dynasties.

But they face a very big dilemma - no fossil fuels.

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

No, nothing.

These fossil fuels were consumed by the first era multinationals. In a mere 100000 years, it is impossible to produce any drop of oil or a piece of coal.

Without enough fossil fuels, people in the hemisphere will be miserable. No matter how smart they are, they can't enter the industrial age. The cost of relying solely on plant combustion to provide energy is too high. To produce charcoal, a large number of people have to mine it, and the productivity is limited. After all, the growth of plants depends on photosynthesis. The total amount of growth every year is fixed, and it is impossible to take anything like coal.

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

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

They have been stuck in the traditional handicraft era. People in the hemisphere can use charcoal to smelt some metals, but limited to the high cost, it is very difficult to further large-scale steelmaking.

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

This slow age has lasted for at least 50000 years, and many historical materials have been lost. Compared with human contemporaries, it is too long.

However, the long exploration can always accumulate production experience. In the long-term opening and closing, the idle upper class began to prefer some spiritual enjoyment, such as mathematics, art and... Archaeological culture.

Archaeological culture, Kalina's biggest variable.

In fact, people in the hemisphere can often dig up strange things in their daily life, that is, the so-called "ancestral heritage".

Like rusty steel bars, concrete bricks and so on, there are some very strange things. Muddleheaded hemisphere people have always thought that it was the traces of life left by their ancestors and would collect these things.

Kalina is a planet rich in oxygen. In a long time, oxygen has eroded most of the first era heritage, so people in the hemisphere who have stayed in the feudal era for a long time have never been aware of them as treasures.

Ordinary people pick up interesting garbage. Those with metal components are directly smelted. Those that look valuable will also be sold to dealers who collect antiques.

Merchants then sold Collectible antiques to the great nobility.

The nobles compare their antiques with each other and suddenly find that modern art and crafts are not as exquisite as those in ancient times. This fact makes them puzzled.

With the development of handicraft industry, why can't it compare with the ancient times? They know what kind of life was in ancient times.

In particular, there has been no way to decipher all kinds of ancestral characters. The number of these characters is very large, which is completely different from what they currently use. Under curiosity, some idle nobles began to organize people to decipher these words.

It was not until an archaeologist preliminarily deciphered the language of "super ancient civilization" that the whole upper class suddenly realized!

"It's not our ancestor!"

"But... There was a super ancient civilization in the world. They are far more developed than us!"

"What is this? Magic? "

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

The discovery of this fact shocked people in the hemisphere.

Then the news spread all over the Kingdom, and the nobles began to loot antiques and collect valuable things.

A great and vigorous archaeological action appeared on Karina. Enthusiastic hemisphere people almost dug the whole planet three feet. In this high oxygen environment, only some shelters buried underground can be preserved.

Just like digging ancient tombs, every time one is excavated, it is a great harvest. Everywhere you can hear the news that so and so has dug up a treasure and become rich overnight

Although the legacy of the whole planet has been lost a lot, it adds up to a lot. These crazy nobles even went overseas to buy, and therefore launched wars of aggression again and again to rob the wealth of other countries.

However, it is these archaeological data that provide a solid foundation for future development.
