In this terrifying planet flowing with natural strong acid, the Silver Star was just silently suspended motionless in the sea of strong acid.

As the saying goes, don't talk and pretend to be a master.

That's pretty much it.

After all, Lu Yu didn't need to observe unidentified objects thirty-five light-years away, he only needed to follow the triangular spacecraft to continuously receive information.

But actually.........

Because of the level of civilization, there is a very obvious difference between the two sides in terms of the concept of length of time.

Maybe a hundred years is already an unacceptable long time for Lu Yu.

But for the members of the higher civilization who have a long lifespan of the Ring Clan, it may only be a short moment, and even that lucky stellar civilization can be patient and use gravitational lensing to observe the situation of the star system for a hundred years.

So it doesn't seem strange that the triangular spacecraft has been squatting here for a hundred or two years.

But obviously Lu Yu didn't have time to waste it here, but it was ........... It's still more important to have points, so he can only endure it first.

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

As a carbon-based creature, he may turn into acidified black carbon, but the environment here is still of great scientific value for humans.

After all, even now, mankind's exploration of Venus has made a big step forward, and now there is a space station with a capacity of 100 people in the orbit of Venus, dedicated to the study of the Venusian environment.

This is just a scientific research base created by the slight remaining resources of Bluestar's strong support for the forward base.

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

It's better to develop Mars, it's easy.

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

But unfortunately, Lu Yu can't.

Because the triangular spaceship is not far away, if this guy finds that the silver star is all scientific and technological creations made by the second-level civilization.

Doesn't it collapse the image of civilization that was even higher than the Huan clan before?

So this wave of ........ is not talking and pretending to be a master, silently waiting for the triangular spaceship to toss and earn points for himself.

The cookie-cutter sea of acid outside could only make Lu Yu curious for ten minutes, and then he could only honestly put on a virtual reality helmet and connect to the long-awaited base zero.

The rare topic discussed online today is not related to science and technology, but related to the military.

The threat posed to humanity by the unknown fleet has gradually leveled off with the continuous explosion of science and technology.

All informed human beings seem to have sufficient confidence to meet this challenge from the universe.

Of course, having faith is a good thing, but human beings still have to be fully prepared, otherwise it will not be faith, but a kind of arrogance that treats one's own civilization as child's play!

Therefore, it is one thing to start training officers for the possible interstellar war that will break out later.

Now strategizing is another preparation, all preparations are for the unknown fleet that human civilization will face!

A circle of high-ranking elders sat at the conference table surrounded by a round table, and Lu Yu looked particularly young when he sat among them.

There is no need to say polite words at this strategic discussion that may determine the future of humanity.

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

A huge fleet is heading towards the solar system, and there are no planetary-level ships like the main warships of stellar civilizations, but there are too many fleets, and they are like black clouds in space.

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

Because there, any star has a distance of at least thousands of years, there is nothing, and if something happens, it is impossible for the civilization fleet to be replenished with any materials, and it is only possible to wait for the energy to run out, and then die, turning into cold cosmic stones, drifting with the tide in infinite time.

And that's just interstellar sailing, and if it's a river-level voyage, it's even more terrifying. There, in order to get an asteroid, you may need to travel at the speed of light for millions of years.

Therefore, stellar-level civilizations, or fourth-level civilizations that have just mastered the speed of light, will never challenge this extreme behavior, but are more about advancing from star system to star system, constantly obtaining materials from the arriving star systems to maintain light speed travel.

The premise of the image simulation given by the military is that the unknown fleet is a fourth-level civilization, and then they came to the solar system for the purpose of replenishing materials and fuel.

After all, human beings were unable to make any sound to the universe before, and in the eyes of this unknown fleet, which is very likely to be a fourth-level civilization, the solar system is just a star system that has not been developed by civilization

The military's simulation proceeded quickly, and the fleet of the fourth-level civilization came to the solar system and suddenly discovered that the indigenous civilization was developing at a rapid pace, and it was also intended to keep them out of the star system.

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

And the material they want to obtain is too large for human beings to accept, because for human beings who want to step into a stellar civilization in the future, they also need a large amount of solar system materials to ensure the foundation of civilization's take-off.

And so, the interstellar war began!

It can be seen that in the military's proposal, there seems to be some dissatisfaction with the Great Wall of Space program.

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

The 3,000 ships pre-built by humans were shattered by the terrifying onslaught of the opposing fleet.

It's not that there is a technological generation gap between the spaceships made by humans and the other party's spaceships, and even in simulations, one human spaceship can even replace five of the opponent's spaceships.

Even with such a battle loss ratio, the opponent's fleet that rushed up like a tidal wave still stubbornly executed the tactics of the redemption and annihilated the human fleet in front of the Great Wall of space.

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

Then the badly damaged engine exploded directly, shattering all the instruments and equipment within a radius of several hundred meters in the vicinity.

The terrible explosion and dozens of secondary engines were directly burned and melted away by the excessive energy load, and the molten metal liquid was raging everywhere like magma from a volcanic eruption, and the interior of the spaceship seemed to have an earthquake, the artificial gravity equipment was damaged, and some instruments lost the attraction of gravity, and began to fly around inside the spaceship, crashing everywhere, with fires everywhere and explosion......s everywhere.

With an explosion of this magnitude, the ship won't be left with even a single recyclable thing. The mechanical structure will be completely damaged, and the metal made with advanced material technology will be completely restored, turning into a pile of scrap copper and rotten iron.

In virtual reality, silence is terrifying.

No one wants humanity to come to such an end.

However, the elder in charge of the docking of the Great Wall of Space program glared at the military representative, and he knew that this guy was clearly secretly rubbing his way to say that the speed of building spaceships was too slow now.

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

No one can be sure whether such a fleet will be sufficient.

But this is already the limit of what can be achieved by human productivity, unless it is in a state of readiness from now on.

"Next simulation."

When the Great Wall of Space in front of him was completely destroyed, and the next thing was to drive straight into the Blue Star, an elder sitting on Lu Yu's left hand finally couldn't stand it.

With the command, the image in front of me suddenly changed. 、

This time, the tactic used by the human side has been changed to start the blocking battle in the Oort Nebula.

With a first-strike attitude, launch an attack on the unknown fleet that has just completed the slowdown.

As the birthplace of civilization, any star system that is rashly approached by a civilization or even the origin of civilization can be regarded as an invasion.

This is the common knowledge of the universe that Lu Yu learned in the Planetary Academy.

Based on this philosophy, launching a first-strike attack on an unknown fleet can never be said to be an immoral act.

In this battle simulation, this unknown fleet seems to be stunned by the human fleet, not only falling into the trap of gravity bombs, but also being successfully attacked by antimatter bombs one after another.

The flash of the battleship's explosion can be seen even in the blue star, and in the days and nights of those interstellar wars, there are countless shining stars on the sky of the blue star.

When this tactic was successful, the wreckage of the Unknown Fleet almost added a Kuiper Belt to the solar system.

This combat simulation looks very pleasant, after all, no one wants to see the terrible fate of their own people after the defeat of their civilization.

But this tactic has come back around, and if you want to carry out such a blocking battle on the Oort Nebula, and prevent the opponent from breaking through the Great Wall of space in one go, it means more ships and more weapons.

This is a very real question.

War, how can it be that weapons are not needed?

This time, everyone whispered to each other.

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

It doesn't matter, I'll make a move.

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

Otherwise, the Silver Star can come back, and there will be nothing to do with the unknown fleet!

It doesn't matter if they pass through the solar system by chance, or if they want to come here to replenish their material and energy.

The Silver Star is here, and they have to sing and dance in the Oort Nebula, outside the solar system!

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

This was the case of the Oort Nebula's unsuccessful battle, but the weapons displayed by Blue Star that were far superior to civilization also brought the two sides into a stalemate.

Then the unknown fleet sent a large number of small ships, among which the robots equipped with the power system were released, they shuttled back and forth between the large ships, transporting one part after another, a large number of robots began to work, began to assemble these strangely shaped, almost inexplicable parts together, and more robots began to lay lines, equipment debugging, parts fastening and other work.

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

In just ten days, the unknown device was assembled into a volume the size of the moon.

And then it ......... It showed its role!

After calculating the orbit of the solar system, it launched an attack on the sun!

Intelligent beings have a very special affection for stars.

Just like the primitive worship of the sun in primitive times, the hungry sun god was created in various civilizations that were isolated by geography.

For civilization, the star is a generous giver of energy, and the energy it exudes gives birth to life, without which life would not have been born at all. In fact, even if the human beings of this era have the current level of science and technology, they are actually still asking for energy from the sun all the time.

As for the extraterrestrial civilizations, they don't have any emotions for the sun, and in their opinion, it is unlucky to hit such a star system, and since they can't get supplies smoothly, it is not difficult to understand how to destroy this star system.

In particular, it can inflict unimaginable blows on mankind, isn't it a perfect means of warfare?

This is also the helplessness of the civilization origin star field being discovered by other civilizations, which is equivalent to the other party having a handle to control human beings.

And destroying a star is 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 stellar core is extremely high, and this is the region where the stellar reaction is most intense and the energy generation rate is the fastest. A star is like a tall building, and the reason why it can stand majestically is because it has a solid foundation.

Buildings that have lost their foundations will undoubtedly collapse immediately, and so have stars that have lost their cores.

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.

When the sudden appearance of external gravity caused a part of the star's matter to undergo the Loch phenomenon, and the balance of the core was broken, the star could no longer maintain a stable structure, and its material was ejected in the direction of the gravity bomb, and the powerful kinetic energy caused a new round of nuclear fusion reaction, and in this instant, it created all the elements in the universe.

The immeasurably powerful energy burst out, and the sun, which laid an irreplaceable foundation for the birth of mankind, is finished!
