Although he was very surprised, Chu Tianjiang did not feel strange.

Obviously, the history of the development of human civilization on the United Continent is actually a microcosm of human history, or a copy of human history.

After mastering the power of the machine, the kingdom of Red grew rapidly.

In less than two hundred years, the kingdom of Rader had built up the most powerful navy on the United Continent, and used it to conquer almost all the islands and capture most of the major ports. Under the threat of strong ships and artillery, the other countries on the United Continent surrendered one after another.

Unfortunately, the Kingdom of Red was not able to complete the great cause of unification.

For the next 500 years, the kingdom of Red flourished. The problem is that after leaving the coastline and rivers, the fleet of the Red Kingdom is useless. On the United Continent, several of the most powerful nations are located landlocked and control the most fertile lands. Even though these countries were all threatened by the Red Kingdom, and some even broke out into a war with the Red Kingdom, they were not conquered by the Red Kingdom.

What's more, other countries have also begun to industrialize.

The hegemony of the Kingdom of Red was maintained for five hundred years, and during these five hundred years, all the countries on the United Continent completed the industrial revolution.

What happened next is obvious.

The strong productivity of industry requires a large enough market to digest, and any industrial country does not have a large enough domestic market to meet its own industrial production, so foreign expansion has become the only way out for industrial countries, and the competition for resources and markets is the main theme of the industrial age.

Where there is contention, there is also war.

About 2,500 years ago, in the 14th century of the United Continent's history, in just one hundred years, three full-scale wars broke out that affected almost everyone. These are three wars against the kingdom of Rader, and three wars of the industrial age. These three wars claimed the lives of hundreds of millions of people, but they also injected a shot in the arm for industrial development, especially scientific and technological development.

After these three wars, history on the United Continent took a major turn.

As with the history of mankind that Chu Tianjiang was familiar with, the key to ending the all-out war within the human race was not peace, but destruction that would be enough to make everyone fearful.

That is, nuclear weapons.

The advent of nuclear weapons not only ended the Third All-Out War and brought the Kingdom of Red into decline, but also ushered in a rare long-term peace for the United Continent.

For the next 1,500 years, the United Continent remained fragmented, but there was no more full-scale war.

Of course, small-scale local wars have occurred one after another, but several major powers that have mastered nuclear weapons have been at peace, at least not using force to settle disputes.

Interestingly, peace does not bring prosperity.

Although the use of nuclear energy has greatly benefited everyone on the United Continent, especially the emergence of controlled fusion nuclear energy, which has fundamentally solved the problem of energy, the development of science and technology has been very slow and even stagnant without the stimulus of war.

To put it bluntly, in peacetime, politicians who have resources in their hands and decide how to use them will never invest a penny more in the science and technology related to war. What's more, there is no reason for interest groups to allow technological development to undermine their vested interests.

This is almost exactly the same as the human civilization that Chu Tianjiang is familiar with.

According to the information obtained from the human shadow, as early as the beginning of the twenty-first century, human scientists have found an effective way to achieve controlled nuclear fusion. Unfortunately, research in this field was quickly terminated due to lack of funding, and the results of the scientists were sent to the library. It's not that there isn't enough money to sustain scientific research, but that controlled fusion technology will affect many interest groups, especially entrenched energy groups. Interestingly, it was the largest energy group in the world at the time that supported the development of this technology. The reason is also very simple, if the controllable nuclear fusion technology is applied, oil will no longer be the number one strategic resource, and even the energy structure of the entire human civilization will change, and the energy oligarchs will invest heavily in the development of oil fields will all become decorations. More importantly, the proliferation of controlled nuclear fusion technology will inevitably cause hegemonic countries to lose their ability to control the global economy, which will also lead to the decline of hegemony. In order to safeguard the common good, it is clear that the energy oligarchy and the hegemonic powers will work together to prevent controlled nuclear fusion technology from entering the practical stage.

Peace on the United Continent lasted for about 1,500 years.

A thousand years ago, the advent of a scientific invention that was not directly related to energy fundamentally shattered the terrifying peace established by nuclear weapons.

This is biochemical technology based on genes.

Through modulation, in addition to being able to make ordinary people have superpowers, there is also an additional effect, that is, the modulator with superpowers is not afraid of nuclear radiation!

It is clear that nuclear weapons are of little value in the face of an army of modulators.

Although the high temperature and high pressure produced by a nuclear explosion still have extremely strong lethality, its principle of action is not much different from that of conventional bombs made by special methods. More importantly, the explosion radius of nuclear weapons is not very large, even if an air explosion is carried out, the high-temperature and high-pressure killing radius of a nuclear warhead with a TNT equivalent of 200,000 tons is only a few thousand meters, and the radioactive contaminants produced by it can pollute an area of tens of kilometers. In other words, the area affected by the high temperature and high pressure of the explosion of a nuclear warhead is less than one percent of the area of radioactive contamination. For ordinary people, the biggest threat to nuclear warheads is the radioactive fallout produced after the explosion. Unfortunately, the modulator is not affected by nuclear radiation, so it is impossible to kill the modulator with nuclear radiation.

The peace of terror was broken, and war was once again the main theme.

It was the largest and shortest-lasting war in the history of the United Continent, affecting all countries and everyone, but it lasted less than a month.

For ordinary people, this is almost a war of total destruction.

Although the modulators are not affected by nuclear radiation, very few people are concocted, and most of them are military personnel, and civilians are almost ordinary people.

After the outbreak of the war, several major powers used nuclear weapons for the first time.

In order to prevent other countries from becoming the last winners after the war, the major powers that possess nuclear weapons not only strike at the powers that also possess nuclear weapons, but also attack all countries by the way. In less than an hour, all cities on the United Continent with a population of more than 200,000 were hit, and those military bases located far from the cities and in remote areas did not escape.

As a result, nearly three billion people died in the war.

In total, less than a million people survived this war, and half of them were modulators.

What's worse is that the large-scale use of nuclear weapons has filled the United Continent with radioactive fallout, and all the land and rivers have been contaminated.

For ordinary people, there is no place on the United Continent anymore.

Of the 500,000 civilians who survived, only about 50,000 survived five years later.

Thankfully, these 50,000 people survived and were exposed to radiation for a long time, which made a fundamental difference for them.

That is, their genes are affected by nuclear radiation, and they are more or less changed.

Luckily, the surviving modulators re-established order and provided civilians with all the resources they needed to survive. In the first hundred years, these modulators continued to help civilians in any way they could, establishing many cities on the United Continent.

It was these 50,000 people, as well as 500,000 modulators, that allowed the human civilization on the United Continent to be preserved.

After about 500 years, the population of the United Continent has recovered to three billion, all descended from the original 50,000 ordinary people. The reconstruction work on the United Continent also lasted for 500 years, and cities, towns and villages reappeared, and people once again lived in peace.

Of course, the situation on the United Continent has also changed dramatically.

The most significant change is that the "Doomsday Empire" established by the modulators has become the only country on the United Continent, and the United Continent has finally achieved great unification.

With the help of scientific materials preserved during the war, science and technology were restored.

What's more, the people who survived are actually the owners of superpowers, but they don't show it, so among their descendants, there will occasionally be some people who are born with superpowers, and even if they don't have superpowers, their descendants have stronger intelligence than their predecessors.

It is in this way that human civilization has been restored on the United Continent and has achieved greater success.

Unfortunately, the Doomsday Empire has focused on biochemical technology, that is, through the study of genes, to fundamentally improve the abilities of human beings themselves. In other areas, especially in the vital space technology, the Doomsday Empire has not invested much, and no progress has been made.

Perhaps, this is also the reason why the Doomsday Empire has been able to grow and develop.

Over the next 500 years, the ruling order established by the Doomsday Empire was accepted by everyone, but no one mentioned a crucial issue.

That is, why is there only such a big world in the world?

Not to mention ordinary people like Memphis, even scientists from the Imperial Academy of Sciences rarely mention it, and are not even allowed to think about it.

To everyone, this doesn't seem to be a problem at all.

It's just that some people definitely know that the United Continent is not the only existence, and the world world where human beings live is not just a piece of land on a sphere. There must be other continents outside of the United Continent, and the United Continent is just a continent within a planet, and there are other planets, as well as other stars.
