Hemispheric civilization was born on the planet Kalina, which is not far from its current position, only about 5 light-years away. If you start the curvature navigation at the highest speed, it will be less than two years.

However, hemispherics have long abandoned their home planet and become a nomadic nation, which is quite rare in interstellar history

It's a long story. Of course, a civilization with strange ideas is cultivated by a strange history.

"Karina star" is just like its name, a very beautiful and gentle planet.

Because the iron element on the planet is very abundant, whole continents are like burning clouds. The exposed backbone of the earth is orange, the vegetation on the planet is emerald green, and the light blue ocean.

The three colors complement each other, and the whole planet is very beautiful.

The intelligent creature of the first era of Karina, known as the "multi ball man", is not the so-called hemispheric man.

Compared with hemispheric people, multiglobes are taller and have a great difference in appearance. They have two tentacles on their heads, while hemispheric civilization has only one tentacle. From the perspective of species, it is almost the difference between humans and chimpanzees.

The history of this "multi global civilization" is too long. It has existed for millions of years and bred a brilliant cultural system.

However, after the multi ball civilization entered the information age, it was skewed by various entertainment trends, and began to indulge in a large number of virtual VR games that directly stimulate the brain. Therefore, it was lax in spirit and entered the low valley of mediocrity.

For millions of years, they have exhausted the fossil resources on the planet, and the whole civilization has fallen into involution, but they have not lit up the important technology line of controllable nuclear fusion. As a result, many global civilizations have been trapped in their own planet for a long time and live on solar energy.

In fact, it can't be said that whether a civilization is mediocre has nothing to do with people's happiness. Multi ball people mate and breed, play games, establish another spiritual world, and have a leisurely life.

If nothing unexpected happens, the multi sphere civilization will continue for a long time until it encounters an irresistible natural disaster: an asteroid impact, a sudden increase in the light intensity of the star, or a gamma ray explosion from a distance will completely sweep the planet

They are masters of the planet, with technology of 0.9 civilization. Natural disasters at the planetary level are not enough to exterminate this civilization.

But with the passage of time, small probability accidents really happened!

It's not a natural disaster, but a man-made disaster!

A notorious five-level civilization - "Green Star civilization", accidentally passed by "Karina star", which was attracted by its unique geographical appearance.

The beautiful "Karina star" is like a magnificent jewel in the eyes of the green star civilization.

In the middle of the Milky way, such beauty can be regarded as the top number in the row.

And because the "multi ball man" has laid too many solar panels on the surface of the planet, like pieces of cowhide moss on the planet, the green star civilization is very unhappy. So the strange green star civilization thought that the multi ball civilization was the destroyer of the Kalina star environment, so it declared war on this indigenous civilization under the banner of protecting the environment.

"Declare... Declare war?"

Zhang Yuan almost choked on his own saliva. A five-level civilization declared war on the 0.9-level indigenous people. This is not shameful at all!

And with the slogan of environmentalism, they make themselves very elegant and aboveboard. Why not provoke the sixth civilization?

As for the outcome of the war, there was no accident.

Multi ball civilization is dead.

As a five-level civilization, green star civilization does not need to destroy these barbarian Aborigines through conventional war.

The phenomenon of "explosion" is a completely barbaric act for the green star civilization. If they destroy the ecological environment in a mess through explosion, what is the difference between them and indigenous people?

Green Star civilization moved its fingers and made a specific gene virus for multi ball people. This virus is so powerful, cold resistant, heat resistant and highly infectious, but its lethality is almost zero. It is not too much to say that it is a perfect virus.

Yes, the real perfect virus doesn't need a high mortality rate, otherwise it can isolate the sick and let them die.

Infectivity and latency are the most important.

Unconsciously, "multi ball people" began to be infected with this disease in large quantities. Because they had no symptoms, they didn't even know they were infected with the disease.

The green star civilization left without taking away any fireworks.

Many people around the world breathed a sigh of relief. An extremely powerful alien civilization ran over, suddenly declared war, and then suddenly left. They were confused and thought they had survived the disaster.

But quietly, there are no healthy people in the world.

After a long incubation, the virus suddenly broke out, just like a set time bomb

"As far as human beings are concerned, biotechnology does not seem to have the ability to manipulate genes and mutate them regularly."

After the outbreak of the virus, it does not directly kill the individual, but invades the reproductive cells of the host and destroys the reproductive ability of multi ball people!

In this way, the first era intelligent creature, multi ball man, fell into a huge nightmare.

This is the biggest malice of the green star civilization. We don't kill life and never kill any life, including intelligent creatures. However, these intelligent creatures that destroy the environment should not reproduce the next generation, so they will disappear quietly.

A hundred years later, the multi ball people who fought against the five levels of civilization and technology finally became extinct

Seeing this, Zhang Yuan sighed deeply.

"What a misfortune it is. An indigenous civilization lives well on the planet, although it is a degenerate civilization. But a level five civilization came and suddenly destroyed them... This kind of thing... "

Only a few words of history can hardly present that sad disaster scene.

A hundred years of struggle and despair condensed into one sentence: they are extinct.

The love and hatred, struggle and laughter, pain and pity of countless lives, whether great men or ordinary people, who have appeared in this civilization, have all turned into nothingness. Five words can sum up their history, "they are extinct."

Zhang Yuan shook his head. In his eyes, many people suddenly found that the whole people could not bear the next generation. The society was in total chaos and fell into a doomsday state. The researchers struggled until they died, and it was still difficult to cross that barrier.

It's really hard to survive when the whole people are poisoned and the technology is not developed enough

"Alas, a weak civilization can only survive on the mercy of others. Weakness is a sin."

Fortunately, the notorious Green Star civilization has been killed by the crimson Industrial Alliance... Who knows, this is just a statement and can't be confirmed.

Then, with the extinction of the first era overlord "multi global civilization" on the planet, the genetic virus lost its host and became extinct.

The rest of life on the planet has no impact, which also reflects the virus fabricated by the green star civilization. It is really very powerful. This virus is like a remote-controlled bomb. It will explode whenever it wants to.

After the extinction of intelligent creatures in the first era, animals and plants grew wantonly on the planet, and soon all kinds of artificial buildings were buried. The law of nature became the only survival law of Karina. Animals ate and ate, and plants began to occupy the original construction site.

From a certain point of view, the environmental protection concept of Green Star civilization is indeed very friendly to other organisms, providing them with a better living environment. Unlike in the past, all animal and plant habitats are insufficient and in a state of exploitation. Different positions lead to different conclusions.
