Time is like an arrow, and time is like a shuttle.

Year 2153!

A full hundred years have passed since the return of human beings to the earth, and the human population has reached 600 million.

Humanity has gone from being able to modify the Earth to being able to transform entire star systems on a large scale.

The giant intelligent Dyson sphere has already enveloped the entire sun, and the endless energy emitted by it has been converted into a huge amount of antimatter by the nearby antimatter factory.

At the same time, in the Earth's orbit around the star, there have been more Venus and Mars, in order to smoothly move these two big guys to the Earth's orbit, human beings began to study the planetary curvature engine in 2070, and it took more than ten years to create two huge planetary curvature engines, and consumed about hundreds of billions of tons of antimatter, which is equivalent to the accumulation of two years of Dyson sphere, which was only one-tenth of the completion at that time.

But everything is worth it, the orbit where the earth is located, the most suitable for human survival, the difficulty of the next planetary environmental transformation is the lowest, and the time required is also the shortest, just a few decades or more, these two originally dead planets have become vibrant, except for the slightly smaller size, they are no different from the earth.

Moreover, in the process of construction, the countless technical difficulties overcome have also accumulated valuable experience for humans to build super-large creations in the future.

Before the Dyson sphere was established, mankind once optimistically predicted that at least in a thousand years, mankind would never worry about energy problems again, but in fact, human energy consumption is growing much faster than human imagination.

As the so-called poor have a poor way of living, the rich live a rich way, the poor can't imagine, the rich man's monthly consumption of the figure, is the money he can't earn in his lifetime, this can also describe today's human beings, when the energy supply is huge, in order to consume the extra energy every day, all kinds of crazy creations began to be built in large quantities.

For example, a gaseous planetary multi-functional mining platform that is absorbing gaseous planetary material from Jupiter and is known as a "planetary vacuum cleaner".

For example, Planet 4 in the Barnard System and Planet 5 in the Sirius System are slowly stripping away rock layers, known as "planetary strippers", and are multi-functional mining platforms for rocky planets.

Another example is a planetary fortress that stays near the earth, is known as the third "ultimate guardian of mankind" on the earth, and can fly at 50 times the curvature of the speed of light.

These behemoths, each of which has a diameter of hundreds of kilometers, consumes an astronomical amount of energy per second during operation, especially the planetary fortress, which is a behemoth with a diameter of 500 kilometers, although it is much smaller than the moon, but the mass is 1.5 times that of the moon.

The alloy layer with a height of 100 kilometers of collapse, unless it is directly hit with a large mass of antimatter, even if human beings use all their strength, they will not be able to break the defense in a short time.

It's not that the amount of antimatter produced can't keep up with the consumption of this bastion of confidence, but that in recent years, humanity has begun to consciously reserve this strategic resource.

Even today's human beings are not at ease in the face of this vast starry sky.

Forty years ago, with the commissioning of the new fourth-generation space exploration equipment "Sky Eye", the detection distance of human beings began to penetrate into the surrounding area of 1,500 light years.

The number of extraterrestrial civilizations discovered has also jumped from three to twelve, and the weakest ones that can be discovered by space exploration equipment are all civilizations that can explore the star system where they are located, and there are also interstellar civilizations.

Human beings have their own strict hierarchy of dangers to various extraterrestrial civilizations.

The lowest is harmless: this kind of civilization, even if it uses its strength, cannot hurt humanity in the slightest, they can only shrink in the star system and circulate, without the slightest threat to the earth.

This type of civilization accounts for the vast majority of all extraterrestrial civilizations discovered by mankind, and more than two-thirds of civilizations are mostly at this level.

The second is the mild threat level: this kind of civilization has a certain degree of danger, they have been able to explore the stars, some powerful have even developed curvature technology, but the huge gap in technology level, as long as there is a war, there is no suspense about the outcome of the victory, such as the Boxing civilization that was destroyed by humans more than a hundred years ago.

The next medium threat level is already a great threat to mankind, this kind of civilization is basically at the same level as human beings, and some of them are even stronger, and it is unpredictable to win or lose in the event of a war.

As for the highly threatening level, and finally the destruction level, it is already far stronger than the human civilization, and in the face of such a civilization, all human beings can do is to flee far away before the other party shows its aggressive intentions.

Fortunately, humanity has not been so unlucky, and what humanity has discovered this time is a civilization that is moderately close to a high threat level.

It is located about 1,200 light-years away from the solar system, and its power tentacles spread across the five surrounding star systems, and it is like a hegemon that dominates all the civilizations around it.

Since it was detected, human beings have been paying attention to this powerful civilization for forty years, and in the past forty years, the number of technological creations in the main galaxy where it is located has been expanding at a rapid rate, not to mention this civilization, and human beings are in fact the same.

More than 100 years have not been able to make mankind forget the years of war, although over the years, the old human beings who have experienced that period have gradually passed away, but the new human beings who have a longer life span are still in the prime of life, and most of them are already in leadership positions, and the sense of crisis in their hearts is still there.

Immediately after the discovery of this civilization, humanity went into a state of war.

That massive planetary fortress, which is the result of this arms race, and even two of them are still under construction.

In addition, in the past few decades, the number of warships built by mankind has exceeded 50,000, and the construction of space defense on the scale of the solar system is completely different from the density and intensity of the glass star at that time.

Compared to the general pessimism of the war with the Bosnians, there is nothing to be feared by humans.

In the past hundred years, mankind's research on energy quantization has become more and more in-depth, and the energy quantum leap technology has gradually matured, and human energy weapons have entered the threshold of faster-than-light.

The military significance of this is not an exaggeration, even if it is a metamorphosis.

In the past, there was no better way for humans to deal with faster-than-light targets except for heap attack density and relying on luck.

On the one hand, there is no accurate detection system, and there are huge errors in the detected spatial fluctuations and specific positions, and on the other hand, the target speed is too fast and the attack distance is too far.

After all, even if the target detection is accurate, no matter how accurately the quantum computer of the fire control system calculates the position that can attack the opponent and launches it.

There are too many variables in the hours or even a day or two that the speed of light approaches the target, a faint fluctuation in space, the refraction of thin air in space, and the occasional random change in the speed of the target, all preparations can be useless.

However, the faster-than-light energy leap weapon completely changed all this, it greatly skipped the shackles of the attacking party's distance and the interference variables in the distance, and the moment it was launched, it could jump to the target in an instant.

Combined with the miniaturized space exploration equipment and more advanced quantum computers, the hit rate of faster-than-light targets has increased by hundreds of millions of times.

Of course, even if it has increased by hundreds of millions of times, because the base is too small, the hit rate of a single attack is still pitiful.

But the war of interstellar civilizations has always been the fire of hundreds of millions of artillery in unison, and the lack of hits can be made up by numbers, even if the hit rate of a single battery is negligible, under the regional coverage strike, hundreds of millions of energy shells wash the ground, even if the target speed is fast, it is useless.
