They use the flesh and blood of dinosaurs to grow their bodies.

He also used the bones of dinosaurs to polish and manufacture the first simple but full of potential tools.

When the last dinosaur on earth was exterminated by them, these ancient people, who called themselves "dragon hunters", had created a splendid civilization and pushed this civilization to a level that was 100 times more advanced than today's earth civilization in the next thousands of years.

Of course, being able to do this was not only due to the inheritance of the primeval civilization from the depths of the Star Sea, but also to the concentration of aura on the earth at that time.

At that time, the earth was in the "rising tide" period of the spiritual energy tide, and the spiritual energy between heaven and earth was extremely strong, even if the flowers and plants were easy to become essences, snakes, insects, rats and ants could activate spiritual intelligence, not to mention that it was originally a carbon-based intelligent life, and it was much easier to absorb spiritual energy to cultivate and establish a super civilization based on spiritual energy to operate, which was much easier than the modern earth.

Growing up in an era of extremely abundant aura, the body structure of the ancient people was also different from that of modern earthlings.

There are only pores and hairs on the skin of modern earthlings.

There are also only blood vessels and neural networks in the body.

However, the skin of the primeval people was covered with mysterious and complex patterns, and in addition to blood vessels and neural networks, there was a third network that was more subtle than capillaries.

All of this is to better absorb the aura, guide the aura into the body, slowly flow along the skin and the third network in the body, strengthen the body and soul, and stir up a kaleidoscopic and infinitely powerful supernatural power.

Relying on such a special structure, the wisdom and combat effectiveness of the ancient people improved very quickly, and it was simply a rapid advance.

After completely occupying the earth for 300 years, they initially comprehended the mystery of shuttling through high-dimensional space, and established the first batch of hyperspace gates, thus discovering two planets that are close to the earth in terms of the concept of high-dimensional space.

That's where it's now called the "Immortal Cultivation Realm" and the "Illusion Demon Realm".

Hidden in the depths of genes, the inheritance from the sea of stars has driven the ancient civilization to continue to explore and expand.

A large number of expeditions and colonists soon formed an expeditionary force and crossed the gate of space to the Immortal Cultivation Realm and the Illusion Realm.

At that time, the immortal cultivation realm and the illusion realm were also in a state of extremely rich aura, strange flowers and plants, and rare beasts, in a state of beauty and beauty.

It's just that there is no highly developed civilization like the primeval earth, only some powerful carbon-based intelligent life, which divides one side and dominates the world.

In the face of the menacing formed expeditionary force, these lonely carbon-based intelligent beings were no match for them, and were quickly suppressed by the ancients.

In this way, the primeval civilization spread from the earth to the immortal cultivation realm and the illusion realm.

It's just that because the environment and aura concentration of the immortal cultivation realm, the illusion realm and the earth are not the same, the frequency and manifestation of the aura gushing are also different, and over time, the Taigu people who migrated here have also undergone many changes.

After conquering the powerful carbon-based intelligent life in the local area, the Swire people even chose to merge with them and turn their descendants into various strange shapes, but very suitable for the local living environment.

- In the history of modern mankind, similar things are not uncommon, conquerors kill all indigenous men, leave indigenous women, give birth to all kinds of mixed races, and in the end, mixed races have become the mainstream, whether it is "slaughter" or "integration", human civilization, this is what it is.

The ancient people were originally from the depths of the sea of stars, an ancient life form of half bacteria and half viruses, blended with the crystallization of various genes on the earth, and did not have any strange ideas of "if it is not my race, its heart must be different", and accepted all this calmly.

In this way, a thriving primeval civilization across the Three Realms has developed vigorously, and it seems that it has reached the point where flowers are brocade, fire is boiling, and it is flourishing for a while.

At its peak, the primeval civilization had already incorporated liquid metal solidification technology, strong and weak artificial intelligence technology, nanomechanical technology, and holographic technology...... All of them have been pushed to the pinnacle.

At that time, the primeval civilization, no matter what tools they wanted to make, did not need to be carefully polished, as long as the drawings and parameters were planned on their supercomputers, and with the click of a button, the nanomachines could automatically assemble the tools they wanted.

Even without drawings and parameters, as long as the requirements are input into the nanomachinery with the ability to think on its own, the tireless nanomachinery can try the most classic appearance and internal structure again and again, and finally find the "optimal solution", which is automatically combined into what the owner needs.

In this way, the entire primeval civilization was occupied by these liquid metal-like mercury nanomachines, and they even entered the bodies of flowers and trees, snakes, insects, rats, ants, jackals, tigers and leopards, as well as the primeval people, helping the primeval people to better transform the earth, and also transform and strengthen their own bodies.

At this time, the primeval people could make any exquisite tool at will.

With the help of nanomachinery in the body, no matter how many injuries are suffered, as long as the aura is abundant, it can be healed in a very short period of time without medicine.

At first glance, nothing can threaten their existence and domination.

As a result, the entire civilization has even entered a period of burnout at a certain loss.

It's a pity that the good times didn't last long.

The existence of the primeval civilization is based on the premise of "abundant spiritual energy".

The body structure of the ancient people was completely evolved from a high-concentration aura environment, just like fish cannot do without water, they cannot do without the surging tide of aura.

After a hundred years of development, nanomachines with the ability to think for themselves have gradually been regarded as a part of the ancient people and even the whole world, and must continue to absorb aura in order to create an "inexhaustible" effect.

Reiki is to nanomachines, just like sunlight is to flowers and trees, it is an indispensable and vital thing.

However, the primeval people at that time did not understand, or they did not want to understand like ostriches with their heads buried in the sand, that the aura could not be so abundant forever.

Just as the tide rises and falls, the sun and the moon rise and fall, and the sea level is high and low, the seemingly inexhaustible aura also has peaks and lows.

The primeval civilization was fortunate to be born in the era when the aura was most abundant on earth, and became a pig in the storm.

- When a storm sweeps, even pigs will fly as long as they hit the tuyere.

But these flying pigs rarely think seriously about whether they really have the ability to fly freely, and how do they land once the wind stops?

Now, the "winds" of the primeval earth have stopped.

When the concentration of aura reaches the limit, it is like climbing to the top of a mountain, although there is a relaxing and pleasant view of the mountains, but then it is destined to be a wave of swooping and rolling down.

"The aura concentration is decreasing!"

This bad news, which is comparable to the sound of a death knell, has set off a panic in the world of ancient civilizations that is a hundred times more serious than the catastrophic era of modern earth.

Growing up in an era of abundant spiritual energy since childhood, the ancient people who took the inexhaustible mysterious energy for granted are like a rich boy who has been clothed and fed since childhood, even if he seems to have unparalleled strength, but in fact his soul is extremely fragile, he is a flower in a greenhouse, and he can't withstand the real wind and waves.

- From this point of view, the seemingly powerful Taigu people may not have been as strong as today's earthlings.

At least, even if today's earthlings don't have aura, they can still rely on their own hands to fight, fight with blood and sweat, hit their heads with their heads, bite with their teeth, punch and kick, how can they fight a bloody road.

But the primeval people lost their aura, like small fish in a dry pond, and they didn't know how to survive at all.

Just when the primeval people were like headless flies thrown into a hot pot, before they could think about how to survive in an environment where their aura was depleted, something even more terrifying happened.

Just like when the tide rises and falls, the sea will be swept away, smashed and swallowed up all the ships sailing on the sea.

In the process of the depletion of spiritual energy, the birth of "spiritual qi bubbles" will also cause disturbances in the high-dimensional space, thus cutting off the originally stable hyperspace channel.

In the era of abundant spiritual energy and stable space, the connection between the earth, the immortal cultivation realm and the illusion realm was quite close, and the residents of either side could easily travel to the other.

But now, the three worlds have been swept away by the fierce and frantic spiritual tide, the stable hyperspace channel has been torn apart, and the earth, the immortal cultivation realm and the illusion realm have become three isolated islands!
