"Horn civilization, we have found the key image!"

"Located in the four-dimensional space coordinates kjs44asd4dfacv41....... you can also observe."

A series of garbled characters seem to be the coordinates of the four-dimensional space, but unfortunately Lu Yu is still in the point of grasping space-related technology.

Is it the lack of basic physical theories? Or is there still a lack of thinking logic, and it is impossible to recognize the spatial structure in front of us? Or is there an irreparable gap in materials technology?

In any case, mankind is now investing a great deal of energy into space technology, but it has not received any return.

Obviously, the research environment of human beings on space technology is more advantageous than that of some sixth-level civilizations, and they can't get so many typical space materials for them to study repeatedly.

The promotion from a first-level civilization to a second-level civilization relies on breakthroughs in energy technology, and the control of nuclear energy has completely changed the way civilizations obtain energy, giving civilizations the ability to change planets and colonize planetary systems.

The more perfect and systematic control of energy, coupled with the breakthrough of intelligence, has promoted the second-level civilization to the third-level civilization, mastering the productivity of colonizing the entire star system.

The breakthrough of the basic theory of the Great Unification has allowed the third-level civilization to break through to the fourth-level civilization, becoming a primary stellar civilization, mastering the light-speed engine, and completely opening the door to the universe.

Breaking through to the fifth-level civilization is to master antimatter and have a warp engine that travels faster than light, and at this point, civilization can transform into a real cosmic civilization, and stars are only the batteries of civilization from now on.

And between the sixth-level civilization, and the promotion of the sixth-level civilization to the seventh-level civilization, there is a gap for Lu Yu.

Judging from the recent research on space technology, this gap is even more difficult than the primitive man directly studying nuclear fusion.

Lu Yu can be sure that from a fifth-level civilization to a sixth-level civilization, the breakthrough point will not be energy technology. Because by the end of the fifth-level civilization, after mastering the antimatter energy supply technology, it has been possible to convert 100% of the mass into energy, and basically the energy technology of the stellar civilization has developed to the top.

However, there is a connection between the development of civilizations, for example, if a fourth-level civilization wants to pursue more efficient interstellar travel, then the related technologies and theories of high-efficiency warp engines will inevitably become the next focus of civilization science and technology.

In order to use such a technology, the more efficient energy use method than nuclear fusion is bound to be a new direction.

The development of civilization is slowly interlocking, and each technology will promote the corresponding scientific development until the complete adaptation of civilization to the universe is satisfied.

Humanity is now involved in the scientific and technological system of the fifth-level civilization, but now scientists can't find the next step. In front of the fifth-level civilization, there seems to be a fog, and this fog blocks the explosive progress of human scientific development.

Perhaps this is the normal path of civilization development, and it should be explored in countless possible paths for the development of science and technology.

Instead of human beings, they are running fast on the road of science and technology, and even to the point that it takes time for the technology to land, otherwise it will fall behind and iterate.

"Space Science and Technology...... It's still too far away. ”

"Maybe the sixth-level civilization is the preliminary research and application of space theory?"

Just like the Wisdom people in the past, although they are only stellar-level civilizations, the Zhizi computers they developed already have some spatial characteristics.

It's just that no one can be sure whether such an application will be aided by the Alliance of Conscious Lifeforms.

Therefore, Lu Yu couldn't say whether the opportunity for the fifth-level civilization to be promoted to the sixth-level civilization was related to space technology, maybe he would be able to uncover it when he captured the sixth-level civilization in the future.

The sixth-level civilization was promoted to the seventh-level civilization, and from the stellar-level civilization to the river-level civilization, which involved the space technology, and now Lu Yu was thinking about how to get it from the Huan Clan civilization.

And the first thing to do now is to pretend to be a master of the Silver Star, which does not speak, and has to think about how to get the observation results of the triangular spacecraft in vain.

Through the negotiation of No. 7, Lu Yu still got it very smoothly.

After all, the Silver Star and the No. 7, which is in charge of foreign exchanges, both show the level of a super-eighth-level civilization, and even the Ring Clan civilization seems to have reached the level of the legendary cosmic-level civilization.

As long as the Horn Clan civilization recognized the level of its own technology, it naturally would not suspect that Lu Yu in it was just a guy who couldn't even control space technology.

After passing the processing of No. 7, what was presented in front of Lu Yu was a magical scene.

There seems to be a layer of transparent glass above the three-dimensional universe, through which Lu Yu can see the distant starry sky through the thick atmosphere of this planet without hindrance.

With the guidance of the seventh arithmetic, Lu Yu will not be lost in the macroscopic and weird four-dimensional perspective.

He had only been stunned for half a second, and his perspective had already shifted to hundreds of light-years away.

In front of you is a neutron star's strong gravitational pull, which deflects light.

Therefore, the scene in front of Lu Yu is also distorted, just like seeing things through smoke, vaguely unreal.

Light can propagate in four-dimensional space, and in his view, the extremely dense and high-temperature neutron star matter has some similarities with the strong interacting materials that make up the Silver Star.

That's where the fun comes in!

Although Lu Yu had arrived in an extreme environment more than once before, he had observed neutron star matter so clearly.

The observation of the four-dimensional space seems to be different from any observation method that Lu Yu is familiar with, even if it is light years away, the composition of matter can still be captured so clearly.

Space chords?

Or is it a special substance that mankind has not yet been able to establish conjectures or theories?

However, the detection can only reach the surface of the neutron star, and the deeper and tighter material structure blocks Lu Yu's snooping, or because this neutron star is not the target of the triangular spacecraft, there is surface information.

The situation of the neutron star was only a quick glimpse, and Lu Yu was under the guidance of the seventh, so that he would not get lost in the strange perspective.

Under the guidance, Lu Yu soon came to the location marked by the triangular spaceship.

It was a spaceship.

Compared to the main warships of stellar-level civilizations, it is not large, only half the size of the moon, and the spherical structure design makes the ship look unremarkable.

At this moment, the spaceship is orbiting a planet at a relatively steady speed, and it seems that it has been captured by the planet's gravity.

Based on its appearance alone, Lu Yu couldn't determine the specific level of technology of this spaceship.

But in the four-dimensional perspective, everything in the three-dimensional is visible, as if sinking into the spaceship, and everything in the spaceship is displayed in front of Lu Yu.

In the process, Lu Yu made new discoveries in this star system, many of them looked like fragments of battleships, some of which probably still had intact shapes, but they seemed to have lost all their mobility, and could only follow a fixed orbit and move slowly.

And when Lu Yu invaded the spacecraft through a messy four-dimensional perspective, No. 7 thoughtfully converted the perspective into three-dimensional, otherwise Lu Yu's current human body would not be able to control this perspective outside of this dimension.

At this time, Lu Yu could finally see the inside of the spaceship, which had completely lost its energy supply, there was no trace of life in the cold space, and he could only barely deduce that this spaceship should be the creation of a fourth-level civilization through some scientific and technological devices.

"Why did the triangle ship send me this ship?"

"This galaxy doesn't seem like the star we're going to examine, right?"

Inside the spaceship, Lu Yu didn't find anything from the corpse of any living organism.

While it is possible that the intelligent race of this civilization is similar to the existence of conscious beings, it is not necessary that they may have given up their physical bodies long ago.

But as Lu Yu explored the abandoned spaceship, he saw the obvious living area module, and saw a large number of dead plants in it.

This indirectly proves that the intelligent life forms in the spaceship may have physical beings, but they mysteriously disappeared from the spaceship.

Building a spaceship is not just a matter of technology, but involves a lot of things. The larger the ship, the more aspects are involved.

A spaceship with such a large volume is not just as simple as the accumulation of building materials, the things involved in it are simply everything, in Lu Yu's estimate, the civilization that can build a spaceship with half the volume of the moon has at least reached the late stage of the fourth-level civilization, and is ready to be promoted to the fifth-level civilization.

The current human civilization has not yet had the ability to create a spaceship of this scale.

Even if a large asteroid on the Blue Star is selected and reluctantly transformed, it will have no value in the spaceship due to maneuverability, defense, attack power, etc. Like Ceres today, it was almost hollowed out by the Forward Base.

But if you want to turn the forward base into a spaceship....... it can only be said that it does not have the ability to travel at high speed at all, and is just a pile of broken copper and iron that is simply piled up.

Then it can be deduced that in terms of the ability of a fourth-level civilization, this spaceship is probably one of the capital ships built by the power of civilization for a while, and it is impossible to abandon it easily.

"If we arrive in person, we can analyze how long this ship has been abandoned."

"But ....... something is wrong!"

"Is there anything about this ship that makes the triangular ship care?"

When Lu Yu was still a little puzzled, No. 7 had already found an answer for him.

A new image popped up in front of me, and a large number of shipwreckage were spread in front of me, which was something that had been involved in the wreck trap.

These large number of ships do not belong to just one civilization. Among these spaceships, there are fourth-level civilization creations, fifth-level civilization creations, and even sixth-level civilization creations, but it's a pity that because they have been cut by space countless times, they no longer have any possibility of extracting technology.

But No. 7 still got a lot of useful information from a relatively intact spaceship wreckage.

There were no lifeforms on that piece of wreckage, and all the parts that made it up were all damaged, and it could still be seen through comparison that its modules were ninety percent similar to Lu Yu's current living quarters.

Basically, it's certain that they come from the same civilization.

That's interesting.

The wreck trap is more than a million light-years away, how could this civilization cross such a long distance to get to the wreck trap?

Moreover, the wreckage trap has been in the RingClan civilization for a long time, and this civilization will appear in the inner layer of the trap, indicating that they have discovered the wreckage trap before the Ringclan.

The triangular spaceship discovered this, so did it allow Lu Yu, a more advanced civilization, to come and see the scene?

"Spatial coordinate point, in another place."

The tip of the seventh sounded, allowing Lu Yu to continue shuttling in the spaceship for a while before stopping in a corner of the spaceship.

It seems to have once been a command room, full of retro computers and lots of display screens.

It seems that in an electromagnetic storm, such a technological creation is more resistant than a holographic projection display.

This is the four-dimensional space coordinate point sent by the triangular spacecraft, and they seem to have found some important evidence here.

was still a reliable number seven, and quickly switched Lu Yu's perspective to the image she extracted.

This is an image observed through a high-precision optical telescope, and a civilized fleet is greatly panicked in the footage.

This should not be a scene in a highly intelligent civilized fleet, especially in the space voyage fleets basically maintain a fast speed, if there is a mistake, there is a spaceship collision accident in the huge fleet, then the speed makes the spaceship with a huge mass directly become a kinetic weapon.

Therefore, the shipboard main engine will coordinate the speed and distance between each other.

This is a coordinated voyage that can be achieved by the fleet of human civilization, and there is no reason why this space fleet that has already stepped into deep space cannot do it.

But panic did happen, and some ships changed direction in the fleet formation without any hesitation, just trying to get out of the fleet.

At this time, Lu Yu discovered that this high-precision optical telescope was a device installed on this abandoned spacecraft, and this image seemed to record the scene before the collapse of this civilization fleet.

The spacefleet stretched out one astronomical unit was so large, but the ships that escaped were only a small fraction.

They were all ships on the periphery, probably less than five hundred.

And there was a huge and innumerable fleet, which stood silently in the void, motionless, without any movement. It's like a creature that has been drained of all its life force in an instant, and immediately dies on the spot.

And then, it seemed that the behemoth that had been invisible appeared in this fleet.

In one bite, hundreds of ships disappeared from the fleet.

In another bite, a huge gap appeared in the huge fleet.

Bite after bite.

The fleet was devoured by invisible beasts.

And this scene is clearly like the planet that was affected by the mysterious weapon before.

It's like [Erase], but it's actually a weapon attack with an unknown mechanism.

Really!

And the vanished wreckage trap was caught here again by the triangular spacecraft, this miraculous four-dimensional space reconnaissance technology.

But if that's all it is, it still doesn't make sense!

After all, they were looking at an unknown object, not the abandoned ship.

Is it a windfall?!

With these questions, Lu Yu carefully continued to look at the image in front of him.
