The primitive version of Jiayu is riding, and it is indeed a dinosaur.

The three-story dinosaur.

It is also the feathered creature Tyrannosaurus rex that has been following Jiayu and wants to eat Jiayu - "turkey".

After nearly a month of domestication, it reluctantly identified with the little monkey, and the two creatures established an initial relationship of trust.

With the help of the Tyrannosaurus rex turkey, more carnivorous dinosaurs followed him.

And soon found several ignorant Homo sapiens colonies.

Almost under compulsion, Jiayu tied every Homo sapiens who was as stupid as a monkey to various dinosaurs.

Each was stuffed with a stone axe.

Assemble this ancient dinosaur cavalry.

In the magma of a volcano dozens of miles away, Jiayu rebuilt the stick sword in his hand.

In ancient times, the first metal sword made by primitive people was born.

…………

Hundreds of dinosaurs, with the stupid Homo sapiens who screamed wildly with the fear of the dinosaurs, rushed straight down.

Rush to the horde of terrifying Neanderthals!

In the face of hundreds of dinosaurs, Neanderthals were vulnerable.

A great battle was fought from the morning of the autumnal equinox, which I don't know when, until the afternoon, when the sun was about to set, and finally the dust settled.

The High Priest could not have imagined why, for hundreds of years, Homo sapiens, like the most docile rock sheep, would be helped by such ferocious dinosaurs!

The bravest warriors of his own tribe have no chance of resisting.

None of the Neanderthals survived.

Tribal sacrifices, warriors, old people, women, children, all slaughtered!

Even the corpses were eaten while they were hot by dinosaurs and primitive people.

As the greatest primitive man in history, the warriors of Homo sapiens reverently offered the most delicious parts of Neanderthals to Jiayu.

Jiayu himself was a primitive man, but he didn't eat it.

It's not because the taste is not used to it, but in his heart, he still wants to take a bite and chew it.

However, he did not stop these primitive people, eating the flesh and blood of human beings who were not much different from them.

Jiayu stepped on the dried blood and walked onto the high platform of the sacrifice.

At the top of the high platform, there is an altar more than ten meters wide, which can accommodate 4 primitive people to sacrifice for "work" at the same time!

The shaman first slit the carotid artery of the primitive man with a sword, and in two minutes emptied the blood of the mentally retarded Homo sapiens, and then the dead primitive man would be thrown to the operating table next to the high platform, and the butchers would cut off the head and limbs and make them into jerky as a ration for all the fall.

…………

Jiayu stood on the high platform of the sacrifice, looking at the altar soaked in blood for hundreds of years, there are several original carved murals.

He was in a daze.

The golden-colored greatsword in his hand was almost stained red with Neanderthal blood.

When the primitive version of Jiayu saw the mural, he was extremely shocked.

"What did Nebula simulate for me? Is it real or not? How could there be such a thing here? ”

The scene carved by the primitive Neanderthals on the altar is like a story of the end of an ancient supercivilization.

The first mural, the recorder of the primitive era, depicts the grandeur of an ancient super civilization city with abstract brushstrokes!

High-rise buildings are lined up, saucer-shaped spaceships fly in the sky, and there are several spaceships on top of the mural.

Although the depiction is rough, the thruster vent and the bridge are still very finely carved.

The second mural is a huge, abstract, symbolic army of monsters that has destroyed this advanced civilization!

The building was in ruins, the flying saucer was broken to pieces, and the spaceship was broken into several sections.

In the center of the picture is a monster that has never been seen before, like a life form composed of countless curves and line segments, and it rules everything.

Behind the altar is a third fresco, which begins to look like a myth.

Neanderthals lined up in four rows, following the illusory golden bridge, towards the planet in the distance of the picture.

This planet Jiayu took a closer look, and it looked like a planet-shaped space station made by some kind of civilization.

The fourth fresco, the last one behind the altar, is already blurred by the blood of centuries of sacrifice.

Jiayu could only barely tell that the artificial planet still existed.

But the passage was closed, and countless people were praying that the passage would open again, hoping to live a heaven-like life.

On the artificial planet, the Almighty God is looking at the praying crowd on the ground, without saying a word.

Jiayu doesn't know why this incomparably glorious prehistoric civilization has not left a trace.

Why would a tribe like the Neanderthals adopt such a savage and bloody ritual of human sacrifice to pray for God's favor?

He didn't know if the copy of the Nebula had actually happened.

Everything is an unsolved mystery.

Where is this planet where ancient civilizations migrated?

Will they come back and exterminate the descendants of the current Homo sapiens?

Everything is still unknown.

…………

In the unknown probabilistic enhancement space, Nebula has basically completed the simulation construction of a small piece of police king Jin's whole body neuronal cells.

There are 86 billion neuronal cells in the human brain, which is only the simplest content of the entire simulation system, and Wang Jin's simulation work has only just completed one-third.

More on the next step.

Nebula needed to simulate the construction of glial cells.

Coming to this point, it can be said that Wang Jin's central nervous system is completed.

After that, simulating his whole body peripheral nervous system, that is, the neural network of the whole body, will be relatively simple.

Nebula was also a little tired.

Six splendid nebula spiral arms, the number of stars is much less, and the brilliant galactic nebula has lost a little bit of luster.

In this space, a person suddenly appeared out of nowhere.

The man was half-crouched on the ground, like a sturdy gorilla, ready to bite at any moment.

"Ojira, Ojima?"

This person has the appearance of Jiayu, but his expression is completely an uncivilized primitive person.

The virtual officer Wang Jin was stunned, "This is Jiayu, why did you just go out for a few hours, and it became like this?" Got into a fight? ”

…………

It was a long time before Jiayu adjusted back from the state of a primitive man.

No longer thinking and shouting like primitive people, but just eating and walking around, a few times from time to time.

Woohoo woohoo.

After Jiayu's sanity returned to normal, he grabbed one of Xingyun's spiral arms with a stomach problem, and asked urgently.

"Nebula Instructor, this copy ...... You made it up, how could you possibly know what happened on our planet at least a few million years ago? ”

Nebulae hummed and shook the air.

"Any information in this universe will not be extinguished, every little thing that happens on the earth will travel outward at the speed of light, and you only need to process the messy light signals to get the full picture of anything. This piece of information was captured from 2.31 million light-years to 2.32 million light-years away, which is very close and the least difficult. ”

The nebula means that it has a camera installed at a distance of more than 2.3 million light-years from Earth.

More than 2.3 million years ago, everything that happened on the earth was "photographed", and almost every photon recorded a huge amount of information.

Jiayu was stunned, "You mean to say...... Did this history really happen? ”

Nebula made a simple calculation, "The probability of existence is 99.999999999%!" ”

Jiayu understood that if he hadn't gone into prehistory, the primitive Homo sapiens would have to go through at least hundreds of thousands, nearly a million years before they could gradually exterminate Neanderthals and occupy the space of the earth.

It is even possible to be exterminated by Neanderthals.

And after he indiscriminately entered, in less than a year, he established a super-large tribe in the Eastern Continent.

Kill not a single Neanderthal on that continent.

In the process of extinction, he also thought that the two civilizations would live in peace and develop together.

But the two civilizations are completely unable to communicate, and there is no possibility of coexistence in terms of genetic structure, way of thinking, and even adaptation to the climate.

In normal history, Neanderthals were eventually exterminated by their new species.

The story of "The Rise of the Ape Star" is being staged at any time.

…………

…………

There was a strange thought that lingered in his mind, but he could not grasp the slightest hint of inspiration.

It wasn't until he unconsciously raised his left hand to look at the time that he suddenly thought of it!

"What about my system? Where's my sword? ”

Xingyun thoughtfully displayed the treasure of the town hall, the Great Sword, which Jiayu had taken away from the museum, in the form of a holographic image.

For the first time, Jiayu began to carefully observe every detail of the sword's body.

Ever since he got this big sword in the Qingcheng Museum, he has been slashing people and monsters everywhere, and he has never taken a good look at this treasure from the prehistoric era.

The sword was excavated from under a set of fossilized dinosaur bones.

The more Jiayu looks, the more familiar it becomes.

On the sword grid, it was originally a square metal block, but later it became a hexagonal metal.

It seems to be the piece of metal he enshrined in the altar during his attack on the southern Neanderthal tribes!

The blade of the sword seems to be an irregular piece of metal found by chance under the altar that sacrificed nearly tens of millions of Homo sapiens in the Neanderthal capital by the river.

I don't know if the gadgets that I installed on Excalibur millions of years later will still be usable.

Jiayu finally understood.

Why did the hilt change to suit the shape of my hand when I first got this sword in the museum?

Why is it that when you first pick up the sword, you have a feeling of flesh and blood?

This is the weapon he used more than 2 million years ago, the name of the sword: "extinction"!

…………

…………

Looking at the virtual image of the Great Sword, he thought of his own war years in ancient times.

Laughed.

"That Tyrannosaurus rex dinosaur fossil should be a turkey...... Brother, I miss you so much! ”

Did you really change history?

Jiayu's mind was a little confused.

He grabbed the pale blue nebula spiral arm with countless stars.

"Master, master, take me farther away, I want to know what the primitive civilization is all about? This civilization is too powerful, right, there are actually large spaceships? Can you still make a Death Star? ”

Wang Jin interjected, "What? Death Star? ”

Jia Yu said, "Death Star, have you ever seen Star Wars?" It is said that in order to suppress the rebellion in various places, the Galactic Empire has created a powerful weapon, the Death Star, who disobeys and shatters the star with one shot. ”

Wang Jin "......"

Nebula ignored him, just showed a row of words in the room that Jiayu could read.

"The second scene is about to begin, 10 ......"

Jiayu was anxious, "10? 10 days? 10 hours? ”

The subtitles began to change, "9...... 8…… 7……”

Jiayu, "I still have a lot of problems, my evolution core is broken, is there a way to remedy it?" My evolutionary ability is too weak, what magic skills do I have? No one in the base listens to me, what else can I do......"

Then the chiayu disappeared.

The pure white room is quiet again.

…………

…………

Jiayu opened his eyes, and it was darkness in front of him.

It took him a moment to distinguish the stars in the darkness and the magnificent nebulae. Every star is so clear.

After looking at it for a while, Jiayu felt that something was wrong.

"Why don't these stars twinkle?"

Then he heard his own heavy breathing.

Wearing a heavy spacesuit, he floats alone in the universe!
