The cold rain silently watered the earth, and a group of humans in black suits stood silently on the rainy earth, their expressions were cold and numb, and their eyes hid cruelty, pain, helplessness and deep fear!

"Here we are." Electricity, wind and rain, flames! At that moment, even the drifting rain was still, and it became a circle, lonely and frozen in the air

Fifteen Grievances silently closed the heavy book, changed his tone, changed his mood, and said to his younger brother Niankong: "Actually, what is the origin of the new human race, no one can give a real answer, because it was too chaotic at that time, no one dared to be 100% sure that what they knew was true, only one thing is worth being sure!" It was a catastrophe that had a hero named Askar Mana. ”

"Well, I really want you to be like that, so that I don't have to take care of you every day. Let's go, it's time to go to school. ”

"Oh, what kind of clothes am I going to wear today?"

Fifteen resentfully looked at this younger brother who was obviously only a month younger than him, but he was so dependent on him, and shook his head helplessly: "Of course, it's too late to wear a school uniform and go quickly." ”

"But," Niankong looked at the oil-stained school uniform with disgust, can this really be worn, and said in his heart

Thousands of years later, this seems to be a warm picture, but behind it lies deep fear and helplessness.

Thousands of years later, human beings are no longer the rulers of the earth, the mysterious void race, the benevolent sages, and the cruel aliens have taken over the dominance of the earth, while human beings are under the protection of the sages and are still alive, and the scope of their activities has been infinitely narrowed, just like those cattle and sheep that were grazed a long time ago, although they are alive, they have long lost their freedom, and it is the strange race that suddenly appeared - aliens that caused human beings to face the catastrophe of extinction.

No one knows how the xenomorph suddenly appeared on the earth, and the records about those have disappeared without a trace in the long river of history, but fortunately, the sages who appeared in time, and the sworn enemy of the xenomorph, the Void, saved the human race that was about to perish.

Although the sages are powerful, they are extremely benevolent, they have extremely strong spiritual power, they can build the strongest defensive positions, and they can also use these positions to complete some terrible attacks, humans can completely expel the aliens with the help of the sages, but they are wrong, the mercy of the sages does not seem to be only in humans, in the face of aliens who seem weak compared to them, they are also within the scope of their mercy, they not only protect humans, but also protect aliens, That is to say, just like humans treated animals back then, they delicately maintain the ecological balance between humans and aliens!

And the only thing that is not protected and intervened by the sages is the void.

The Void is the spokesperson of the mystery, their figure is extremely mysterious, and there are very few records about them since ancient times, but it suddenly appears from the air in various strange ways to hunt aliens, and then disappears.

According to the remaining information of human beings, the power of the void is as good as that of the sages, and they seem to have the ability to move in the plane, and they are even stronger than the sages in this regard, but it is a pity that they never communicate with humans, and the only possibility for them to appear in the sight of humans is that they are hunting aliens, and aliens can be said to be powerless in the face of the void, but despite this, the number of appearances of the void is very small, and the number of aliens is very large, Therefore, despite the existence of the Void, the blow to the Xenomorph was actually not huge.

Xenomorphs, as the natural enemies of humans, are the species that humans want to know deeply about! Because of that deep hatred and fear!

The cruel alien has an insect-like appearance, has the walking posture of a human being, and its powerful spiritual power, although it is not as terrifying as the sage, but it has a means of attack called resonance, that is, to use the advantage of numbers to improve their spiritual power level, theoretically if the number is enough, this power can even resist the sage, but it is clear that this is just a theory, how huge the number is needed to complete this theory, no one knows, because no one has seen it so far, and the best image of people is that the alien is, The only creatures they can brutally hunt are humans themselves!! That's right, they never hunt other creatures, and in terms of food, there are reports in many records that the aliens were found to be vegetarian creatures by dissecting the old and dead aliens, so it means that the aliens don't hunt humans for food, so people can't figure out why the aliens kill humans ruthlessly.

And humans.

Tens of millions of years ago, human beings perfectly developed their brains and created a powerful power called spiritual power, which was just like the special function that existed in many movies and novels at that time, which could kill people invisibly and control the wind, rain, thunder and lightning of nature. One disaster after another befell the world, the earth changed, the earth's crust changed violently, the continents were scattered into small islands, the small islands merged into continents, the rivers froze into glaciers, the glaciers dissolved into oceans, and human beings were barely able to adapt to all the great changes with the newly developed spiritual power! But with the passage of time, human beings finally can't bear the ravages of nature! Strange species, fission of the earth! Everything, everything.

It is not until today, thousands of years later, that mankind has finally been reduced to the state of this moment.

Nowadays, there are only five major places where human beings can survive on the earth, and the combined area of these five bases is not as large as half of Asia thousands of years ago.

The number of human beings has also shrunk dramatically due to alien shapes and changes in the environment, and the total population is about 900 million people so far.

In the face of this miserable number, the current human beings no longer feel miserable, because the facts have worn out their proud self-esteem, and it has been proved that they are no longer dominant, so human beings have long been accustomed to putting down their self-esteem and living under the protection of the sages, the sages sent some clansmen to settle in the five strongholds of the human race, and laid a defensive position barrier in the five strongholds to prevent the invasion of aliens, so that the human beings were firmly imprisoned in the five strongholds, and at the same time the condition of providing protection was exchanged for the knowledge sharing between humans and the sagesHuman beings are also willing to exchange this for their own stability.

So how long can this stability be stable? Whether the ultimate fate of human beings is silently reduced to captive domestic animals, or ruthlessly eaten away by aliens, no one can see the future

Let's turn our attention back to the original place, one of the five strongholds, the empty stronghold.

The Empty Stronghold is the smallest of the five strongholds, but it is also the safest stronghold, because he is in the middle of the other four strongholds, and the other four strongholds are like the city wall to protect the empty stronghold, so human beings think that the empty stronghold is the safest place, and the safest place should be used to protect important things, and the root of everything is the descendants, and the descendants are even the most important things!

Therefore, the largest educational institution of mankind, the Board of Education, was set up here, and it was stipulated that most of the minors in the five bases must be transferred to the empty base after three years of birth, and spend the next fifteen years under the education of the education committee, until they reach the age of eighteen, they can be sent back to their original hometowns, during which they are not allowed to leave the empty base unless there are special circumstances, otherwise they will be found guilty and punished.

For tens of millions of years, in order to survive, human beings have long forgotten how to write the word freedom.

And our story is quietly coming in this country where there is no freedom.

Fifteen Grievances and Niankong, who was wearing a school uniform full of oil, hurriedly left from the dormitory and rushed to the first-level college of the Board of Education, Fifteen Grievances is only twelve, and his immature face may be because he has to take care of Niankong all year round, and he has more tenacity that he shouldn't have, and his short black hair and those big eyes that are infinitely gentle give people a very peaceful and assertive feeling.

Niankong, may be the reason why the name is too down-to-earth, Niankong's hair has been relatively small since he was a child, and even if it grows out, it is pitted, so Niankong simply shaved his hair from childhood to adulthood, a pair of eyes are bright but it's a pity, the eyelids are too obstructive, and all the bright places of Niankong's eyes are perfectly covered, only the small beanie eyes remain, sometimes even Niankong himself is thinking, he is really related to the fifteen grievances, this appearance is not at all!

According to the regulations, people between the ages of 3 and 12 complete the initial new human course at the first-level college.

During this period, the first-level academy can rely on the performance of the period, and distribute everyone to the second, third, fourth, and fifth level according to the level of spiritual power, each level is a conceptual field of spiritual power, the higher the level of course, the better the person, the more excellent people in the human realm after the age of eighteen, the better they will be treated, and even have the opportunity to work directly with the sages and learn more powerful spiritual power from the sages.

In today's human world, it is everyone's dream to be able to join the fifth-level academy, but according to legend, there is actually another level of existence in the Board of Education - Level Zero.

The awe-inspiring word of zero level spreads in every corner of the academy, and it is said that people of this level are all world-level powerhouses, what is the world level? Their spiritual power can compete with aliens, voids, and even sages, and their responsibility is to try to compete with the powerful aliens and save humanity from thousands of years of slavery!! But the existence of the zero level is like a void, and no one knows whether it really exists or not.

Fifteen Grievances and Niankong walked into their class 202 class with a slight rudeness, because the first level takes the longest time, so the first level has the largest number of people and the largest class 202 represents of course not two hundred zero two, but the second of the second group.

"Ah, it's finally there." Niankong lay on his seat tiredly, planning to take a good rest, fifteen shook his head helplessly, if it wasn't for Niankong's insistence on listening to the story early in the morning, and then because the school uniform was not washed, how could he be so late in the morning.

is also convinced of this younger brother who is inversely proportional to himself in terms of appearance and personality.
