"Turn on visual recording."

Ian doesn't play any nonsense, and now is not the time to be shocked, he directly asked the chip to record all the murals he saw with his eyes on video!

The murals are crude, but very clear and charming. Obviously, the painters are professionals who have studied this field.

Ian held his breath and carefully observed the scenes in the mural.

The mural in front has been damaged and can only be seen from the Broken Moon.

After the fragments of the moon fell to the earth, all living beings on the earth were surrounded by flames, and the towering cities and buildings collapsed in the meteorite rain, and those flying vehicles and airships also fell with black smoke—— This should not be caused by meteorites, but a large-scale mechanical failure. A strong electromagnetic shock or a change in the spiritual energy field swept the entire city. Residents in robes and various costumes scattered in fear on the streets.

Their appearance and characteristics are different. Ian also found common races such as humans, elves, and dwarves. There are also many demihumans with various animal ears and animal characteristics, and sea descendants also appear.

And if you look closely, you can also distinguish the differences between the white people, the iron people, the red people and the golden people from the pigments that have not faded.

It seems that in the pre-epoch, many races of the present have appeared, but there is no distinction between the races. Some people still have cyber-modified parts on their bodies. They walk on the streets equally, but suddenly encounter catastrophe.

The impact of the meteorite was just a prelude. With the collapse of the moon, the light on the earth was gone, and everything on the murals became black and white. Ian speculated that it might be an artistic expression that all electronic instruments were temporarily unavailable.

Then, the scene returns to the coast—a sky-high tower is collapsing.

Something even more terrifying seems to have happened in the ocean... Although there is no description of the meteorite falling, huge tsunamis, earthquakes and geological changes are happening. It is these natural disasters that have destroyed all coastal cities, and Tongtian Tower is not immune either. Sink into the sea with the prosperous city.

However, deep in the ground, a base that was originally designed to resist natural and man-made disasters is still operating.

That's Sequoia Base.

The people in the Sequoia base seemed to be arguing, because of the cover of the earth's crust and sea water, the electromagnetic waves that seemed to interfere with the entire Terra world or the influence of other psionic fields did not interfere with them, and there were still colors inside the base.

But they still fell into a panic, a group of people around a glowing thing were beating each other and civil war, many people died in the base, until the four leaders stood up and reached an agreement.

They made four keys, representing 'energy', 'maintenance', 'circulation' and 'future' respectively, locked many dangerous and damaged areas in the base, and carried out transformations inside the base.

Only when the four keys are gathered together can those blocked dangerous areas and the gates of the base be opened.

The natural disasters outside are still going on, but the interior of Sequoia Base has been stabilized, and the four leaders have jointly managed it. They have successfully established an internal cycle inside the base, borrowed the ubiquitous light to cultivate and raise meat, and maintained enough number of people.

Time flies, and the elder leaders who were already old before the moon shattered passed away one by one, and the other leaders who followed up were also very good, leading the internal staff of Sequoia Base to continue to maintain the ecological circle and repair many facilities inside the base.

This section of murals is skipped very quickly. Just a few paintings tell about the change of several generations of leaders. Obviously, the painter is not very clear about this period of history, or feels that there is no need to describe it in detail—in short, several generations Leaders have changed, and the Sequoia base has always maintained stability.

However, time is always the biggest killer.

Soon, Ian understood why the mural was specially painted for the process of leader change.

Because, after a clean water irrigation facility was destroyed by meat animals, the leader wearing 'green' clothes and representing 'circulation' showed no worries, and everyone else was silent.

obviously.

They have forgotten how to maintain this facility.

Maybe not forgotten.

Ian watched this mural silently. He knew very well that in a highly differentiated modern society, many functions are replaced by extremely professional maintenance machinery or professional workers. The machinery is familiar, and it is impossible for the maintenance workers to master the technology of repairing all the siege equipment.

Except for spaceships and space exploration systems that carry as few people as possible, it is basically not necessary for professionals to master multiple skills.

The larger the civilization and the more sophisticated the department, the stricter the division of employees, and the more people it needs to maintain the 'knowledge' needed for its own existence.

To put it simply - although everyone knows basic mathematics or advanced mathematics, except for mathematicians who specialize in mathematics, few people know what they are usually studying.

The rest of the techniques are the same.

After the natural disaster, Sequoia Base chose to be self-proclaimed underground to avoid natural disasters and isolate themselves from the world. They established a complete ecological system and used the energy of the base to raise animals and grow food, which solved the problem of survival.

However, when all the first-generation Sequoia staff gradually aged, or even died, the loss of technology was inevitable.

Their descendants did not have the conditions to receive a comprehensive higher education like them. Even if they mastered a lot of technology, they would never be able to cover everything and draw inferences about other cases from one instance.

Not to mention, there may not be professionals who can repair water purification facilities among this group of people.

According to Ian's own personal experience, this kind of thing is usually outsourced-cheap, efficient and professional, and it really needs to be staffed when recruiting people.

So, the recession sets in.

In addition to water purification equipment, many other equipment began to have problems.

Of course, there are only a few that cannot be repaired, and most of the key facilities are the key points. Those first-generation Sequoia Base people have already anticipated this problem, and their children and descendants certainly cannot compare with their most elite parents. , but the level has not dropped too much, and the civilization of the pre-epoch can be regarded as an intellectual who has completed higher education.

However, what should the heirs of their heirs do?

If this continues, in less than three generations, the Sequoia people will turn from the adherents of the previous era into outright technological barbarians-they have mastered some high-end technologies, but they cannot carry out further analysis and development.

In order to change this, the man in blue and white, who represents the future and sustains the leader, thought of many solutions.

—For example, using a huge machine to let people learn knowledge.

——Or artificially cultivate an external memory organ, record key knowledge in it, and transplant it from generation to generation to pass on memory and technology.

——Another example is to engrave knowledge directly in the blood, and as they grow up, human beings can gradually understand the knowledge in their own blood.

These are the methods that the civilization of the pre-epoch has been developing for a long time, and has already become quite proficient.

In the end, because the huge learning machine was too extravagant, easy to damage, and unable to manufacture some key parts, they chose to modify their own blood and an external memory organ as a way to help future Sequoia people maintain their technical level. method.

They put newborns and even fertilized eggs in jars similar to culture bins, and then prepared them to write a lot of knowledge into their instincts... There are a lot of genetic engineering equipment in the Sequoia Base, which I saw with Ian Many alien ecosystems match.

Bloodline inheritance is not difficult for them.

——Now, Ian has almost understood the source of the Sequoia natives.

The Sequoia natives are undoubtedly the descendants of the staff of the Sequoia Base!

It’s no wonder that most of the Sequoia natives are Jinzhimin, because among the former staff, the Jinzhimin who are the most adaptable to the environment have the greatest genetic advantage, and most of the newborns born after intermarriage are Jinzhimin... Other races are not adapted, so The ego suppresses the phenotype gene and ensures the continuation of the ethnic group.

But here comes the problem...

Sequoia Base, or in other words, the South China Sea ruins group, has sufficient energy, a lot of resources, and a complete ecological circle-the life here is definitely more comfortable than living outside.

At the very least, the indigenous ancestors living in the base have never worried about food, nor have the whole family 'adaptively' become that short due to lack of nutrition.

"Why are they going out? Giving up al Qaeda membership to become 'indigenous'?"

With such doubts, Ian gradually looked behind the mural.
