In the history of the world of Kolo, at the beginning, on the edge of the ancient ocean 100 million years ago, it was some kind of vertebrate creature that first stepped on the beach, looked at the vast land, breathed the primeval air, and reached a critical turning point in evolution in a state of confusion. Without that moment, there would be no human civilization.

But in the history of the Rota civilization, at the beginning of another biosphere hundreds of millions of years back hundreds of millions of years older than the beginning of the biosphere familiar to Croò, at that moment, in a very different environment, the first person to land was an invertebrate.

As a result, the evolution of life branched, and in tens of millions of years of evolutionary accumulation, in that ancient biosphere, invertebrate intelligent beings called themselves "Rota" appeared.

That was the starting point of that civilization.

Amazingly, perhaps because they are also carbon-based creatures, the biosphere in which they live is also somewhat similar, and the development trajectory of the Rota civilization is somewhat similar to that of human civilization.

They were the first use of fire, then the power of machinery and electricity, and then the age of electronic information. However, they are particularly good at the study of biology, and even in this area have long reached the point where human beings cannot reach the dust.

The Rota civilization has perfectly analyzed more than ninety-eight percent of the animals on the planet, and has constructed countless possible but unverifiable animal types, but there is one thing...... They didn't dare to touch it anyway.

That's the plant.

In the biosphere in which the Rota civilization lived, plants and animals were in opposite positions. Animals can obtain energy in a similar way to photosynthesis, but plants need to parasitize animals and suck flesh to survive.

The plants in the biosphere of the Rota civilization have gone astray on the path of evolution, and after countless extinctions caused by plants, the Rota civilization completely destroyed all plants on the planet.

The last remaining bloodthirsty plants were locked up in an absolutely secure underground research institute, and the Rota civilization, believing that it had swept away everything that hindered the development of civilization on the planet, ambitiously explored the planet's moons, and launched manned ships to many nearby planets.

The Rota civilization threw a glimpse of the endless galaxy with confidence.

Sadly, it's only a glimpse.

It wasn't until that moment that the Rota civilization knew nothing about the planet beneath its feet.

At that moment, the bloodthirsty plants that should have been completely wiped out and almost only existed in the nightmare of the Rota civilization suddenly appeared in every space where Rota's intelligent creatures lived.

Every city, even the undersea immigration city or even the lunar immigration city, these places where bloodthirsty plants did not exist at all, were occupied by bloodthirsty plants in just a few days.

Even, these bloodthirsty plants that kill wildly, are difficult to kill, can move on their own, and can kill parasitic animals and sow seeds in the blink of an eye, which is countless times more powerful and terrifying than those recorded by the Rota civilization!

It's like...... Those bloodthirsty plants were born from the deepest nightmare of the Rota civilization.

After nearly 100 years of struggle, animals finally lost to plants.

The Rota civilization, which has spread for 8,000 years, has initially entered the universe at the level of science and technology, and once had the pride of every rapidly developing civilization. Until this moment, in the mighty bloodthirsty plant, declared extinct.

They built many underground shelters, but it wasn't the inhabitants who sheltered, but the heritage, the legacy of the Rota civilization, and everything about the Rota civilization was recorded in the core of the electronic intelligence.

At the same time, in order to prevent the loss of the data due to the damage of the electronic intelligence, they also used another method that could carry the endless years - the shelter was densely packed with all the building types and common tools of the Rota civilization, and many stone tablets were engraved with their words......

In this way, they have survived everything of the Rota civilization in the most enduring way possible. The supreme leader of the Rota civilization announced to his people in a hollow voice that the Rota civilization was officially ...... because the number of individuals was so small that it could not even maintain basic reproduction Annihilation.

Eventually, the once-glorious civilization of Rota vanished into the dust of history, and endless years shattered their surface ruins into dust. The ecological catastrophe finally came to an end, and after the bloodthirsty plants devoured the last animal on the planet, these strange organisms also went extinct on their own.

I don't know if it's a coincidence, the destroyed biosphere returned to its original state, and in the 100 million-year-long biosphere reset, new life sprouted again in the chaotic sea.

Then came the origin of human civilization in Kolo......

……

Survival or destruction, that's a question.

This question, even if it is placed on the state or even on the individual, is enough to make people ponder for a long time. When this problem is placed above civilization, it brings about vicissitudes that are deeper than the years.

That grand history of the prosperity of civilization, the hasty and strange destruction of civilization, is like a drama that is about to be pushed to the climax and is cut off in the most exciting place!

"You are great, you are ...... It's also sad. Xiao Yao said softly.

"The Rota civilization has long recognized the fate of destruction, which is inevitable, and there is no point in fearing it." The synthesized voice said calmly, and in that tone, there was a nobility that was beyond the reach of human beings in the face of inevitable destruction.

Silence, in the face of the destruction of a civilization, all words of praise or regret are pale.

"Rota is not afraid of destruction, Rota only wants to be remembered." The synthesized voice was still abruptly altered without emotional fluctuations, with the excitement of an intelligent being, "We hope you will know that we have been in this world. We didn't get into that galaxy, but we really worked hard. ”

If Xiao Yao didn't guess wrong, this passage was not the logical language of the electronic intelligence in front of him, but the last words of the civilization that was destroyed 100 million years ago.

"Rota Civilization...... Since you have existed, and you have looked up at the starry sky on the same planet as us, it is the responsibility of humanity to remember you. Luo Yunfan's voice was extremely serious, "I don't know if I have the right to represent the entire human civilization, but at this moment, I know that in the face of this greeting that has been shuttling for 100 million years, I have an obligation to help you." ”

"Thank you for your commitment, humanity." "Then the Rota civilization will give you a gift in return—a startling guess made by our scientists on the eve of civilization's destruction: there were many other civilizations before humanity and Rota. These civilizations, like the Rota civilization, are almost all abruptly destroyed at a certain critical juncture! This destruction will be so complete that the biosphere will be reset after each destruction! The change of the global environment has led to the fact that each repeated civilization is completely different! ”

"What!" Everyone exclaimed in unison, this blockbuster fact was far beyond their expectations, the existence and destruction of the Rota civilization had overwhelmed them, and at this moment, there was an even greater shock hidden behind this shock!

The electronic synthesizer continued without hesitation:

"The memory inheritance of the Rota civilization begins, the tombstone system, and the mission is completed."

"Mission duration, 98340234 years."

"Database sorting, over."

"The 'tombstone' electronic intelligence mission is complete, and the unit is about to be shut down permanently."

"The transfer of the memory of the Rota civilization has been successful, humans, it is a pleasure to meet you, thank you for your willingness to remember our existence."

"The Last Message of the Rota Civilization: Live, Humanity."

One by one, the synthetic voices that were not mixed with any emotion sounded in an orderly manner, and the bright metal tombstones were extinguished little by little, until they lost all their luster, and the surface of the metal became old and decayed, as if the previous 100 million years had been compressed to this moment.

Fortunately, this 100 million years of waiting was not in vain, this emotionless electronic intelligence, this lonely watchman with a mission, and the last recorder of the Rota civilization 100 million years ago, in the end still waited for the existence that he had to wait.

Finally, Xiao Yao lowered his head and whispered, "Rota, good night." ”
