Black technology: starting with space jump machine

In this terrifying planet with strong natural acid, the Silver Star just quietly floated on the sea of ​​strong acid without moving.

As the saying goes, pretend to be a master without talking.

This is almost the state.

After all, Lu Yu does not need to observe the unknown objects thirty-five light years away. He only needs to follow the triangular spacecraft to receive intelligence continuously.

But in fact...

Due to the level of civilization, the two sides actually have a very obvious difference in the concept of time length.

Maybe a hundred years is already a long time that is difficult for Lu Yu to accept.

But for the members of the advanced civilization with a long life span of the Ring Clan, it may be just a short moment. Even the lucky star-level civilization can be patient and use a hundred years to use gravitational lens to observe the situation of the star system.

So it doesn't seem strange that the triangular spacecraft squatted here for one or two hundred years.

But obviously Lu Yu didn't have time to waste with it here, but at least the points were more important, so he could only bear it for now.

In the living area, Lu Yu looked at the terrifying environment outside through the holographic projection.

As a carbon-based creature, he would probably turn into acidified black charcoal, but the environment here is still of great scientific research value to humans.

After all, even now, human exploration of Venus has made a big step forward. Now there is a space station in the orbit of Venus that can accommodate hundreds of people, which is dedicated to studying the environment of Venus.

This is just a scientific research base created by the slightly surplus resources of the Blue Star's strong support for the forward base.

But even if such a little energy is allocated, judging from the data collected from this scientific research space station, it is still quite difficult to develop Venus with the current leaping human productivity.

It is easier to develop Mars.

And now if the environment where Lu Yu is docked can help collect some data and even make some attempts, it may contribute to the development of Venus.

But unfortunately, Lu Yu can't.

Because the triangular spacecraft is not far away, if this guy finds that the technological creations made by the second-level civilization are all from the Silver Star.

Wouldn't it collapse the image of civilization that was higher than the Ring Clan before?

So this time... just pretend to be an expert without saying anything, and wait for the triangular spacecraft to toss and turn, so as to earn points for himself.

The monotonous acid sea outside could only make Lu Yu curious for more than ten minutes, and then he could only put on the virtual reality helmet and connect to the long-awaited Base Zero.

The rare topic discussed online today was not technology-related, but military-related.

The threat brought by the unknown fleet to humans has gradually become stable with the continuous technological explosion.

All informed humans seem to have enough confidence to meet this challenge from the universe.

Confidence is of course a good thing, but humans still need to make sufficient preparations, otherwise it is not confidence, but an arrogance that treats their own civilization as a joke!

Therefore, starting to train officers for the interstellar war that may break out later is one aspect of preparation.

Now formulating strategies is another aspect of preparation, and all preparations are to meet the unknown fleet that human civilization will face!

A circle of powerful bosses sat at the conference table surrounded by a round table, and Lu Yu looked particularly young sitting among them.

There is no need to be polite at this strategic discussion meeting that may determine the future of mankind.

At the beginning, it was a virtual image given by the military.

A huge fleet is heading towards the solar system. There are no planetary-level ships like the main battleships of the star-level civilization among them, but the number of fleets is too large, and they are connected together, like a black cloud in space.

In the universe, the place where meteorites fly around is not the most dangerous place, but the empty place is the most dangerous place.

Because there, any star body is at least thousands of years away, there is nothing there, and if an unexpected situation occurs, the civilization fleet cannot get any supplies. It can only wait for the energy to run out, and then die, become a cold cosmic stone, and drift in the infinite time.

This is just a voyage between star systems. If it is a galaxy-level voyage, it will be even more terrible. There, in order to get an asteroid, you may need to fly at the speed of light for millions of years.

Therefore, a star-level civilization, or a level 4 civilization that has just mastered light-speed travel, will never challenge this extreme behavior. Instead, they will advance to each star system and continuously obtain materials from the star systems they arrive at to maintain light-speed travel.

The premise of the image simulation given by the military is that the unknown fleet is a level 4 civilization, and their purpose of coming to the solar system is to replenish materials and fuel.

After all, humans were unable to make any sound to the universe before. In the eyes of this unknown fleet that is most likely a level 4 civilization, the solar system is just a star system that has not been developed by civilization.

The military's simulation image progressed quickly. This level 4 civilization fleet came to the solar system from afar and suddenly discovered that the indigenous civilization was developing at a rapid speed, and it was also intended to keep them out of the star system.

For the fleet that has begun to lack materials and energy, they must enter the star system to obtain nourishment, otherwise it means that they will not be able to maintain the current fleet size and may develop to the point of abandoning civilization members.

And the amount of material they want to obtain is so large that humans cannot accept it, because for humans who will enter the star-level civilization in the future, they also need a large amount of solar system material to ensure the foundation of civilization.

So, the interstellar war began!

It can be seen that the military's proposal seems to have some dissatisfaction with the Space Wall plan.

After all, the first scene is the appearance of the Space Wall being broken by endless aliens.

The 3,000 spaceships built by humans in advance became fragmented in the impact of the opponent's terrifying fleet.

It is not that there is a technological gap between the spaceships made by humans and the spaceships of the opponent. Even in the simulation, one human spaceship can even replace five spaceships of the opponent.

Even with such a loss ratio, the opponent's fleet that rushed up like a tide still forcibly implemented the exchange tactics and annihilated the human fleet before the Space Wall.

A circle of bigwigs looked at the last human spaceship in front of them indifferently because the engine was severely damaged, the output power began to be unstable, and some parts of the engine even caught fire, causing a large-scale energy short circuit, resulting in sound and fire everywhere inside the spaceship.

Then the severely damaged engine exploded directly, smashing all the instruments and equipment within a few hundred meters around.

The terrible explosion caused dozens of secondary engines to be burned and melted by the excessive energy load. The melted metal liquid was like magma from a volcanic eruption. It seemed that an earthquake had occurred inside the spacecraft, the artificial gravity equipment was damaged, and some instruments lost the attraction of gravity and began to fly around inside the spacecraft, colliding everywhere, with flames and explosions everywhere...

Under such a degree of explosion, the spacecraft will not leave even a little recyclable material. The mechanical structure will be completely damaged, and the metal material made with superb material technology will be completely restored and turned into a pile of scrap copper and rotten iron.

In virtual reality, it was terribly quiet.

No one wanted humans to have such an ending.

Instead, a big man in charge of docking the Great Space Wall plan glared at the military representative. He knew that this guy was clearly secretly saying that the speed of building spacecraft was too slow now.

When facing an unknown fleet in the future, the plan of the Great Space Wall is only 3,000 warships.

No one can be sure whether such a fleet is large enough.

But this is the limit of human productivity, unless we start to prepare for war from now on.

"Next simulation."

When the Great Wall of Space in front of him was completely destroyed, and the next step was to drive straight into the Blue Star, a big man sitting on Lu Yu's left finally couldn't stand it anymore.

With the order, the image in front of him suddenly changed. ,

This time, the tactics used by the human side became a blocking war in the Oort Nebula.

With the attitude of preemptive strike, they launched an attack on the unknown fleet that had just completed deceleration.

As the birthplace of civilization, any star system that rashly approaches a civilized star field, or even a star field where civilization originated, can be regarded as an act of invasion.

This is the cosmic common sense that Lu Yu learned in the Planetary Academy.

Based on this concept, launching a preemptive attack on an unknown fleet cannot be said to be an immoral act.

In this battle simulation, this unknown fleet seemed to be stunned by the human fleet. Not only did it mistakenly fall into the trap of gravity bombs, but it was also successfully attacked by antimatter bombs one after another.

The flash of the warship explosion could be seen even on Blue Star. During those days and nights of interstellar war, countless shining stars appeared in the sky of Blue Star.

When this tactic was successful, the wreckage of the unknown fleet almost added a Kuiper belt to the solar system.

This battle simulation seemed to make people happy. After all, no one wanted to see the terrible fate of their own civilization after the defeat.

But this tactic came back again. If you want to carry out such a blocking war in the Oort Nebula, you have to prevent the other side from breaking through the Great Wall of Space in one breath, which means more spaceships and more weapons.

This is an extremely realistic problem.

How can war not need weapons?

This time, everyone whispered to each other and discussed it.

Sitting on the right side of Lu Yu was Professor Han, who asked Lu Yu's opinion in a low voice.

It doesn't matter, I will take action.

Although I really want to say this, the reality is that Lu Yu has not found the way back to Blue Star yet, and he may miss this interstellar war to defend the solar system.

Otherwise, the Silver Star can come back, and there will be no unknown fleet!

Whether they are passing through the solar system by chance or want to come here to replenish materials and energy.

As long as the Silver Star is there, they must sing and dance in the Oort Nebula, outside the solar system!

After a period of discussion on the second simulation, the military finally released the third simulation.

This is the situation where the Oort Nebula blocking battle failed, but the weapons displayed by Blue Star far exceeded civilization, which also led to a stalemate between the two sides.

Then the unknown fleet sent a large number of small spaceships, among which robots equipped with power systems were released. They shuttled back and forth between various large spaceships and transported out one component after another. A large number of robots began to work and began to assemble these strange and almost inexplicable parts together. More robots began to lay lines, debug equipment, tighten parts, and other work.

With the hard work of the robots, in the center of the fleet, a huge unknown device is taking shape rapidly. With the terrible productivity of the fourth-level civilization, it is like a snowball rolling on the snowfield, and its volume is getting bigger and bigger.

In just ten days, this unknown device has formed a volume the size of the moon.

Then it... showed its role!

After calculating the orbit of the solar system, it attacked the sun!

Intelligent creatures have a very special feeling for stars.

Just like the primitive worship of the sun by humans in the primitive era, all civilizations isolated by geography have created hungry sun gods.

For civilization, stars are generous energy donors. The energy they emit has given birth to life. Without stars, life would not be born at all. In fact, even if humans of this era have the current level of technology, they are actually asking for energy from the sun all the time.

For alien civilizations, they have no feelings for the sun. In their opinion, it is simply unlucky to hit such a star system. Since they cannot get supplies smoothly, it is not difficult to understand why they want to destroy this star system.

Especially, it can also inflict unimaginable blows on humans. Isn't it a perfect means of war?

This is also the helplessness of the star field where the civilization originated from being discovered by other civilizations, which is equivalent to the other party having a handle to control humans.

And destroying a star is actually not as difficult as imagined. For a star, its stability comes from the core.

Due to the compression of its own gravity, the material density of the core of the star is extremely high. This is the area where the star reaction is the most intense and the energy generation rate is the fastest. A star is like a tall building. The reason why it can stand majestically is that it has a solid foundation.

A building that loses its foundation will undoubtedly collapse immediately, and the same is true for a star that loses its core.

The opponent's weapon is a high-frequency gravity bomb. When these bombs come to the sun at a speed that is difficult for humans to intercept.

The sudden appearance of external gravity causes part of the star's matter to undergo the Roche phenomenon. When the balance of the core is broken, the star can no longer maintain a stable structure. Its matter is ejected in the direction of the gravity bomb. The powerful kinetic energy causes a new round of nuclear fusion reaction. At this moment, it creates all the elements in the universe.

An energy so powerful that it was difficult to estimate suddenly exploded. The sun, which laid an irreplaceable foundation for the birth of mankind, was destroyed!
