The city wall was behind him, Gao Qi finally saw the wilderness.

There are no forests, no farmland, and nothing but weeds that are half a man tall.

After leaving the city gate, there is a cement road. The cement road leads to a roadbed that is higher than the flat ground. That is the former highway. You can still see villages on the highway, both far and near, but now it must be a ruin of the village without anyone.

Not everything is taught in college, so Gao Qi doesn’t understand many things, but he will definitely know some common sense.

For example, why don’t you farm near the city? It’s because the Second Catastrophic Beast War lasted for about five years, and the city was the main target of those beasts, so every city is a battlefield, and countless beasts died around each city.

The death of strange beasts will pollute the land. It is not that the contaminated land cannot be planted, but that the food grown is poisonous and people will go crazy after eating it, so these polluted land will naturally not be used again.

In order to fight against alien beasts, humans used all the weapons they can use, including nuclear bombs, so outside the city, but slightly farther away, the main source of pollution is nuclear radiation.

The residual nuclear radiation after the nuclear bomb explosion is actually not strong, so the harm caused by nuclear radiation is ranked behind strange beasts and is farther away from the city walls. However, the closer the city is, the less unusable the land is. This is a problem that every city will face.

Fortunately, the number of strange beasts is limited after all, and the residual radiation from the nuclear bomb cannot cover every inch of land, so as long as it is far enough away from the city, there will naturally be land that can be cultivated.

What Gao Qi never understood before was why cities refused to accept and help those deserted people. In his opinion, even in the ignorant ancient times, human beings knew that population size was the most important resource. So in today's extremely need for population resources, why do those who are in charge of cities not only refuse to accept those deserted people, but even those who were born and raised from cities and received higher education have to be driven out?

It is okay to drive people out of the city, move some people out of the city, and then let some deserted people live around the city, establish gathering areas in an organized manner, and conduct basic management of people in the gathering areas, and establish basic order. Then will not human society be restored naturally?

This question seems simple, but he never gets an answer. However, in his opinion, the best way to solve the problem is that no one can use it.

But after three energy explosion incidents, just today when Gao Qi had to leave the city, the moment he left the city gate, he suddenly understood what Professor Su meant by the words "Carnivorous Eater".

After two major catastrophes, humans retreated back to the city-state era. In Gaoqi, this was undoubtedly a regression of civilization. An important reason for this regression of civilization is that everyone believes that the third catastrophe will definitely come, and humans will eventually perish, and it will not take too long.

People will be short-sighted after despair. If there is no future at all, timely enjoyment will definitely be the consensus of the vast majority of people. Of course, not everyone in this world will despair, but it is not one person who controls the city, but a group. When a group reaches a general consensus, it is difficult for what happens next to change direction by the will of a certain person.

Those city controllers have already obtained most of the resources. They only want the best living conditions and enjoy the present, rather than rebuilding human civilization.

The city can be self-sufficient, but the number of people it can accommodate is limited after all, and the population is growing very fast. So when the inner city is near its limit, people will naturally drive people to the outer city, and people who do not need them can only drive outside the city.

Egoism is the mainstream value of human nature. If you live your own good life behind closed doors, who will care about those vulgar people who don’t know at all and will inevitably be very dangerous?

Chaoxicheng established a pioneering group and opened a farm outside the city. No matter what the starting point was, Gao Qi believed that this was the beginning of establishing initial contact with the deserted people and slowly starting to establish order outside the city, and it was a good start.

But with three energy explosions, this good start is likely to end.

Speaking of this, we must explain the basis of the existence of a city, especially the basis for why a city can operate in a closed manner.

First, let’s start with the first catastrophe. The first catastrophe was a sudden invasion of aliens.

A fleet of alien spacecraft of higher civilization suddenly appeared, three motherships stayed in outer space, and then a large number of small spacecraft entered the atmosphere and launched an indiscriminate attack on humans.

Aliens used energy weapons to attack human cities with some kind of microwaves, but humans had no ability to fight back at all, so nearly half of humans died in just three hours.

Humans could not respond at all, but humans survived because the alien attack lasted only three hours later. Three alien motherships exploded in outer space, and small spacecraft in the atmosphere fell to the ground one after another.

When humans opened the first small spaceship that fell to the ground with anger, they found that there were no aliens inside. Those who entered the atmosphere to launch attacks were only components of the alien weapon system.

As for the wreckage of the mothership, it was not until three months later that it gradually began to fall to the ground under the influence of gravity. For more than a year, the night sky would be illuminated by the burning fires when the wreckage of the alien mothership entered the atmosphere.

This was the first catastrophe, which made humans realize their fragility and ignorance. Humans were destroyed in ignorance and saved in ignorance, but they didn't even know what aliens looked like.

As for the miraculously destroyed aliens, we can only speculate that they were done by higher-level alien civilizations, or the help of God. Apart from setting up conclusions in an idealistic way, there is no other explanation.

The first catastrophe almost completely destroyed humans, but it also promoted the development of science and technology. Humans have obtained many key technologies, and the most critical one is controllable nuclear fusion.

With nearly infinite energy such as controlled nuclear fusion, humans can make breakthroughs in many technologies, including agriculture, of course.

Humans built buildings to plant food, cultivate without soil, and combined with the uninterrupted light brought by infinite energy, factories that can plant crops without land were born, so humans also had the basis to completely operate a city.

Therefore, after experiencing the first catastrophe, humans actually entered a period of rapid recovery, with population growth and breakthroughs in key technologies, and humans may even enter a higher dimension of civilization.

But only six years later, a door with strange light appeared. Behind the door was a strange world, and countless strange creatures surged out from behind the door with strange light.

Four star gates appeared in four places. Behind the four star gates, four extremely powerful alien beasts appeared, and four extremely powerful alien beasts led countless alien beasts to launch attacks on humans.

It also happened inexplicably. Then, two days after opening the four star gates began to disappear one after another, and the four extremely powerful alien beasts also died one after another, and they were deaths of unknown causes.

This is the beginning of the second catastrophe. After the death of four alien beasts that were enough to destroy humans, the remaining alien beasts continued to attack humans, and the worst thing is that these alien beasts can reproduce.

The war of strange beasts changed the world, humans gave birth to superpowers, and of course mutants appeared, and humans also used walls to protect themselves and the city.

Five years after the war between the strange beasts, another star gate opened and another powerful super beast appeared. However, this time, the star gate disappeared for only three seconds, and the fifth super beast disappeared after appearing. Some people said that the super beast was dead, and some people said that the super beast did not die but hid.

This is the second catastrophe. Because it was caused by strange beasts, it is also called strange beast wars. In this war, humans gave birth to psychics, and of course mutants appeared. In addition, after humans eliminated the city wall for many years, they encircled themselves again in the city wall.

Strictly speaking, the second catastrophe has not ended yet. Because the alien beast still exists, the important reason why humans return to the city-state era is also the most fatal reason, which is that humans have lost the ocean.

The ocean has been completely occupied by alien beasts, the land is shared by humans and alien beasts, and the sky is controlled by humans. However, air freight alone is obviously unable to maintain the freight demand between several continents. Lu Yuan is also extremely risky because of the widespread distribution and cannot be completely eliminated. Therefore, various cities are actually isolated islands, and it would be strange if there is no city-state in this case.

The origin of the city-state is roughly like this, and now it can explain the origin of the deserted people.

When the city residents were also defenders and strange beasts fought for five years, no matter what the reasons for the deserted people were, they were indeed absent from the war. So when the war ended, those who had not made any contribution to the city wanted to enter the city and share the survival resources with the city defenders, and the result was imagined.

The city residents look at the desolate people as defenders, which is guilty of original sin.

In the eyes of the deserted people, the abundant survival information is the original sin of those people in the city.

The urban residents are organized and have resources, and are still winners of the war of strange beasts. They have an overwhelming advantage over the deserted people and will inevitably be able to dominate. Therefore, although those deserted people dream of entering the city, they do not mind entering the city and taking away everything from the people in the city, they can only survive in the wasteland with difficulty.

During the two catastrophes, the human beings who lost hope, driven by human nature, built a new world on the wasteland, a strange but reasonable world.

Not everyone can clearly understand the world. Most people just live in a daze, waiting for the third catastrophe in fear. However, Gao Qi is now one of the few people who can see the essence of this world clearly and one of the few people who can figure out their positioning.

Gao Qi positioned himself as a person abandoned by the city. He knew how he should survive, but he didn't know how to change his destiny.

But now, after three energy fluctuations in three days, everything is different.

These three energy fluctuations are very likely to be the precursor to the third catastrophe, or it may be the third catastrophe that has already occurred, but these are not important to the height. What is important is that the first energy fluctuation is at the center of the explosion, the second time he is still there, and he has a very strong hallucination during the two energy fluctuations. If this can be regarded as a coincidence, it would be a bit too coincidental.

But hallucinations are the opinions of others. No matter how reasonable Han Ruofeng and Huang Fei said, Gao Qi still doesn't believe in all the hallucinations he experienced. The overlapping world, those vortexes, and the light spots in nothingness, everything is so real.

The most important thing is not vision, but feeling, the feeling of regret and sadness that has appeared briefly.

Regret and sorrow were just a short moment, but it made Gao Qi unforgettable, making him impossible to forget, and making him firmly believe that it could not be an illusion.
