Of course, the main body of the so-called "savages" is still the people who can't stand the rule of the demon clan and flee to the bottom of the earth in the dark age of the rule of the demon clan in the past tens of thousands of years. When the rule of the demon clan collapsed, they also stepped on the same road and fled to the bottom of the earth.

This is because, at the junction of the earth's crust and mantle, the environment is extremely bad. Not only is the oxygen available for breathing a fatal problem, but also the temperature is extremely high. Ordinary human beings simply can't adapt to the outdoor environment without air circulation system and cooling array. Soon after entering the field, they have annihilated one after another.

The demon clan, and the mankind ruled by the demon clan in the "Great Dark Age", have their own unique advantages.

Li Yao now knows that the so-called "demon tribe" and "human race" are the same thing. In fact, the "30000 years of great dark age" is the cruel oppression and domination of human beings.

However, it was an era of highly developed biochemical technology, and the research on the release of gene power reached its peak.

In order to explore underground mineral veins and use geothermal energy, many human beings are forced to accept genetic modulation, and become various demon tribes with little oxygen consumption and extremely drought and high temperature resistance, and even become strange giant reptiles.

After gene modulation, human beings are equivalent to breaking the "gene lock" in their bodies. The probability of gene mutation of their offspring is much higher than that of ordinary people. Generation after generation, such "human race" or "demon race" escape to the ground. Their offspring, under the subtle influence of harsh environment, further mutate, consume less and less oxygen, and are more and more resistant to drought and high temperature, Even in some mutant species, there is a fine layer of plants growing on the skin, plants devour carbon dioxide, spit out oxygen, demons devour oxygen, spit out carbon dioxide, such a wonderful relationship.

At first glance, this kind of demon clan seems to have become the essence, but in fact, it is just a poor man who is forced to migrate to such a bad environment.

Therefore, it is extremely difficult for the human beings in 10084 region who came down to the bottom of the earth in the era of the star sea Empire to adapt to a deeper life away from the refuge and human civilization. However, for those Terrans and Demons born in the era of the great dark, a very small number of their descendants can still live in the dark in the form of "savages".

In addition to savages, there are also spirit beasts, demon beasts, spirit plants and demon plants. No matter the demon emperors and demon gods in the dark age, or all the spiritual civilizations after the Xinghai Empire, they all want to explore the underground. In addition to building shelters and colonization bases in the underground, they also use the methods of gene modulation and radiation mutation to cultivate countless people who can adapt to underground hypoxia Creatures in dark and hot environments.

They tried to copy the whole ecosystem on the ground, so that they could expand their living space more than 100 times. However, 99% of the experiments on underground organisms failed. The cultivated spirit beasts, demon beasts, spirit plants and demon plants were at best adapted to the artificial environment in the refuge and colonization base, just like rock insects, It can only be found in a comfortable laboratory from birth to death.

However, after many shelters and underground towns were destroyed by the earthquake and magma eruption, 1% of the experimental creatures escaped. They were not only difficult but also lucky to get through a lot of difficulties. They survived tenaciously and became wild monsters and demonized plants!

The relationship between these monsters and rock insects is like that between wild boar and domestic pig, or between wolf or dog.

Li Jialing told Li Yao that although savages and monsters are ferocious, they usually don't easily attack the established towns like 10084 District, because although the refuge system here has collapsed, there are still some defense formations that have not completely failed, and the people here have also exchanged a large number of rock insects and the upper class residents for many powerful offensive magic weapons, If the savages didn't fight to the death, they were unlikely to swallow a town at a time.

What's more, there are also contradictions between savages and savages. They are divided into different ethnic groups and tribes. The hatred between them even lasts for more than ten thousand years. Most of the time, savages and savages fight against each other. On the contrary, they don't fight with the residents of 10084 district.

Li Yao asked Li Jialing, what is the hatred between savages?

Li Jialing replied that the savages gradually evolved into different tribes according to their origins and different times of going deep into the earth. The savages of this tribe were all oppressed human beings who came to the earth in the great dark age of 30000 years, but the savages of that tribe were the powerful members of the demon clan who were defeated and fled when the Xinghai Empire rose. Don't these two tribes have natural hatred?

When the two tribes were fighting with each other, the Xinghai empire on the ground collapsed again, and a large number of people who had just sprouted the idea of practitioners fled to the bottom of the earth. Although most of them stayed in the refuge, a few wanted to use the power of savages to make waves. In this way, it added fuel to the fire, Make this endless dark war more chaotic and cruel.

Even with the passage of time and the annihilation of civilization, most of the lights of civilization fade from the bottom of their minds, but the brand of hatred has been passed down from generation to generation. Up to now, even these savage tribes don't know why they want to fight with hostile tribes, which has become an instinct engraved in their gene chain.

Li Jialing told Li Yao that there are three savage tribes dormant in the dead area near 10084 Town, which are called "heijia", "yeyi" and "honghuan".

As the name suggests, the black beetle has an extremely strong black shell. This shell not only has a strong defense, but also has a very special structure like a solar panel, which can store the high temperature underground and convert it into part of the necessary energy for survival, greatly reducing the demand for food, It will reduce unnecessary foraging and hunting behavior to the limit and greatly improve the survival ability.

The night winger has a pair of broad membranous wings, which are not used for flying or gliding in the rugged cave and narrow underground space. Instead, they can wrap the whole body of the night winger and turn it into a cold giant pupa. On the one hand, they can lock up the loss of body temperature and water, and on the other hand, they can prevent other underground hunters, To spy on them.

Many residents in 10084 District believe that after wrapping themselves with their skin wings, the yeyi people will become a cold stalagmite, able to go into a special hibernation state without eating or drinking for several years. Of course, this is overstatement, but it also shows the survival ability of the yeyi people.

The red ringer is the most terrifying hunter in this area.

Black armour and night winger's talent is more defensive, while red ring's gene mutation is more offensive.

They have a pair of red eyes that are extremely sensitive to infrared rays, and have evolved ultrasonic detection organs similar to bats. These two abilities enable them to perceive everything around them clearly in the dark without any light.

With the help of powerful hunting ability, the red ring people have been fighting against the yeyi people for thousands of years, and even the skin organs of the yeyi people may have evolved to avoid the prying of the red ring people.

It was not until the black beetles moved here from other places and fought with the night wingers against the red ring that the war of the savage tribe returned to the balance of power. This is only the most crude statement. Outsiders naturally neither understand nor are interested in the specific situation.

However, recently, earthquakes near 10084 area have become more and more frequent, which seems to have destroyed the habitats of many monsters and demonized plants. Monsters and demonized plants are the main hunting and gathering objects of the savage tribes, and most of the food sources have been destroyed. The conflicts between the savage tribes have become acute.

If such contradictions are not resolved in time, they will evolve into two possibilities.

On the optimistic side, the three savage tribes, heijia, yeyi and honghuan, will all be destroyed in a fierce battle.

But it's also possible that if none of the three tribes had any food source, they might temporarily endure the hatred deep in their genes and join forces to attack the nearest 10084 town. After all, the hum and haw of thousands of fat rock insects can travel all the way down the crack to the bottom of the earth.

It was against this background that long Yangjun took some compressed food to the activity areas of the three savage tribes, heijia, yeyi and honghuan. With her, there were many carefree believers - in addition to the believers in 10084 towns, there were many believers in four digit towns and even higher.

In the concept of worry free religion, all human beings are brothers and sisters. No matter what class they live in, or even the underground wilderness without numbers, they are worthy of help and salvation.

After hearing Li Jialing's introduction, Li Yao frowns and wants to pursue long Yangjun's coordinates with him and go deep into the savage tribes.

When he passed the "towering tree" in the middle of 10084 town again, he suddenly changed his mind.

"Wait a minute."

Li Yaodao said, "tell me where the air circulation system of 10084 area and the core magic unit of cooling array are. Take me to have a look."

As Li expected, the core magic units of the air circulation system and cooling array are all under this "towering tree", that is, the main control crystal brain.

These two things are the lifeblood of the underground people. Once they are damaged, they will either suffocate without oxygen or be heated to death by extreme high temperature.

However, the underground people do not know whether it is out of fear of the "immortals" or out of absolute trust in the "forget worry tiannv". They believe that the guests of forget worry tiannv will not harm them. Unexpectedly, none of them dare to come forward to stop their investigation, but just shrink their necks and watch from a distance.

There are doubts, confusion and tension on the faces of the young onlookers, but on the faces of the middle-aged and old people, there is only the usual, submissive calm and silence.

The magic weapon of air filtration and circulation is one of the essential basic magic weapons in the navigation of the star sea. Every star ship has it, and it can't be more popular.

What's more, Lee Yao is the little prince of ventilation ducts. He has a deep research on various forms and structures of ventilation ducts and air circulation systems, so there is no possibility of failure.

He opened the shell of the magic weapon unit like flowing water. The carbon dioxide screen, filter and pure oxygen generator inside made Lee's expression sink slightly.
