The upper limit speed of the universe is the speed of light.

The disappearance of pulsars is only more than 20 days, and its macroscopic impact on the universe is only limited to 20 days of light cones.

The spaceship in front of him did not show any traces of its activities in the vicinity during the previous monitoring of the seventh.

This means that it is coming from somewhere outside the light cone of the pulsar vanishing event.

That's interesting.

Rushing to the pulsar, or a boring guy like Lu Yu, came to take a look after receiving the broadcast from the pulsar. Either they have been paying attention to the pulsar's situation before, and when it was frozen into a [glass ball], it immediately came here from a long distance.

Whatever the situation, Lu Yu was surprised by the high-civilization spaceship in front of him.

"We should just jump away! After all, judging from previous experience, all civilizations turn to conflict when they encounter unexpectedly, so why waste time here, can they provide us with space technology? ”

"I think that judging from the technology displayed by this spaceship, it is not the same as the stellar civilization, which will blatantly act as soon as we meet, so it is better to try to communicate?"

That's right.

The spaceship that showed a certain amount of space technology in front of him did not look like a stellar civilization.

According to Lu Yu's strange attributes, judging from the fact that they must fight when they encounter a stellar-level civilization, they may be able to stay and have a good talk?

Maybe I can get the whole star map from him!

Therefore, in the discussion of experts, Lu Yu obviously chose to support the exchange faction.

"Hello, civilization has come suddenly, we are the Horn Clan."

Well, Lu Yu, as a virtual horn clan, had no guilt and asked No. 7 to send a reply to the spaceship: "May I ask what is the purpose of your coming here to find pulsars?" ”

He had already received enough benefits here that he could leave at any time, so Lu Yu was very hard to get straight to the point.

Rather, this message seemed to wake up the ship that was very close, and it reluctantly pulled away again, and only stopped when it regained an astronomical distance.

Well?

That's subtle.

The other party who takes the initiative to approach is more like the frightened party.

However, the universe is so big, and there are thousands of strange civilizations, or civilizations that do not conform to the logic of human thinking can basically be regarded as strange by human beings.

But in the eyes of their civilization, human behavior may be strange.

Lu Yu, who had already understood this on the Planetary Academy, was not surprised by the ship's actions.

Just waiting for it to stop again, it sent a message: "I have visited this pulsar, and you may not believe it, but a special form of life was born on this extreme celestial body. ”

"Out of curiosity, I stayed and taught them some basic science and technology, this kind of microscopic life with neutrons as a special form, has computing power beyond intelligent lifeforms."

"In a matter of microseconds, they were able to grasp the knowledge I had imparted and even deduce it perfectly."

"They can quickly evolve into a higher civilization, but if I want to give the technology I have to other races, I need the permission of the civilization to authorize it......"

The spaceship, which was far away, was unusually honest and told the reason for its arrival.

That's right, they are the Enlightenment civilization that neutron life forms once mentioned.

"Such a civilization with potential, once developed, will become one of the staunch allies of our civilization."

"After I left the faster-than-light communication device on the pulsar, I hurried back to civilization to try to convince them to open up their permissions and cultivate this special life with great potential."

"But unfortunately, after nearly 10,000 years of absence, I couldn't convince my fellow clansmen, and one day when I was still trying hard, I suddenly received a brief signal from the speed-of-light communication instrument that was automatically triggered, which is a mechanism that is triggered when there is a huge anomaly in a pulsar."

So I hurried over and found out that the pulsar was gone......... So I can only ask questions to those of you who are still there. ”

"Excuse me, Horned Civilization, do you know where this pulsar has gone? And where did the neutron lifeforms on it go? ”

Judging from the information Lu Yu had, most of the information transmitted by the spacecraft was in line with the description of the Enlightenment civilization.

But there is only one thing,

Neutron life forms didn't say that pulsars have faster-than-light communication devices?

Forgotten, perhaps? After all, they selectively forgot a lot of things in order to transform pulsars, so that they could squeeze out enough transformation power.

However, the members of this unknown civilization in front of him are also knowledgeable, and they suddenly realized the terrifying speed of technological development of neutron lifeforms, if he can give the great unified theory to neutron lifeforms in advance, then there will be nothing to do with Lu Yu.

Lu Yu thought about it, but there was no need to hide it, as the first civilization to help neutron lifeforms, he was also qualified to know the glorious story of neutron lifeforms.

Especially without their help, the neutron lifeforms would not be able to send broadcasts, and Lu Yu would not have been able to find them, let alone earn such a large amount of points.

So, Lu Yu described what happened before.

"Cosmic-level civilization?"

"Have they really developed towards a cosmic-level civilization?"

"And there was no resistance from the rebooters? Could it be that the Great Universe broadcast was real before? ”

The information from the spaceship full of questions made Lu Yu have an inexplicably happy mood rippling in his heart.

Because the broadcast of the universe was transmitted by him himself, the rebooters can be regarded as the last nail that he personally nailed the seal.

Lu Yu didn't need the civilization of the Great Universe to thank him, he only hoped that what he had done would not be ignored by other civilizations.

It would be enough to wake up the civilizations that had been scared by the rebooters and hide in the darkness, so that they could once again shine the light of civilization in the great universe, so that this universe would no longer be so silent.

And now, he has finally met a civilization that has mastered advanced technology, and how can he not be happy when he talks about it.

As long as civilization remembers it, then this announcement will slowly sprout like a seed.

It wasn't until the first ninth-level civilization willing to believe in it stepped forward and made a cautious attempt, and then let them touch the door of the cosmic-level civilization, that they would understand that the content announced to the great universe was the greatest blessing to the civilization born in this era.

"It's a rare civilization that can communicate well."

Lu Yu, who was in a good mood, gave a rare positive evaluation of the spacecraft in front of him, and with such a good start, the foundation of communication was naturally established.

Lu Yu wanted the star map of this advanced civilization, and the spaceship seemed to want to know more details about the promotion of neutron lifeforms.

The two sides hit it off and communicated on the site of this pulsar.

……………

When Lu Yu was communicating with this self-proclaimed neutron life form enlightenment civilization, a high-profile thing was happening on the Blue Star.

The development of civilization must be accompanied by an increase in the scope of influence.

In ancient human times, a valley could be used for the survival of an entire civilization. After reaching the middle and late stages of a second-level civilization, the space and support needed by this civilization will drive humanity out of the home planet and begin to occupy the entire star system.

In this process, 5 to 10 percent of the speed of light is sufficient.

Taking the current solar system as an example, if it is going back and forth between the forward base and the Earth-Moon system, the spacecraft often has to slow down soon after accelerating to 10% of the speed of light, otherwise the reserved deceleration distance is not enough, and it will not be easy to enter the orbit of the forward base.

After reaching the stellar civilization, the energy required for the development of their civilization has far exceeded that can be provided by a single star system, so the development of multiple galaxies has become necessary.

At this time, the distance of a few light-years or more than a dozen light-years makes the light-speed engine crucial, and when the distance expands to hundreds or thousands of light-years, the warp engine is the choice of civilization.

Such a process of civilization often takes more than 100,000 years to evolve.

Because a civilization is not only the development of science and technology, but also the development of its society, and the history of humanity will have an impact on the process of civilization.

This seems to be ineffective on the Blue Star.

Because technology is developing so fast, social and human history is not even prepared for it.

Because most of the scientific and technological development in recent years originated from Lu Yu's journey to the stars, not from his own civilization.

Otherwise, every time there was a big explosion of science and technology before Bluestar, it was actually inseparable from the humanities and history.

This is true both in the Steam Age opened by the Renaissance and in the Cold War when the two currents of thought collided to give birth to the Information Age.

However, the source of scientific and technological development in recent years is not itself, so now it is the rapid development of science and technology that drives the transformation of thinking, which can be regarded as a wonder in the development of cosmic civilization.

On this day, a large fully automated factory in China was in a state of total martial law for a few days.

In particular, the area around the assembly plant has been directly transformed into a military camp, with dozens of tents erected on an open field.

There are not only drones around, but also a large number of soldiers wearing mechanical exoskeletons patrolling back and forth, and even laser weapons set up in some important hubs!

The barrels of the guns that glow with a faint blue glow indicate that they are in a state of charge, like an indifferent Grim Reaper who can be dispatched at any moment, intimidating any threatening creature from approaching!

In the large assembly plant, a large number of miniature cameras are watching every detail, and a group of experts and scholars are watching the situation through virtual reality.

And they were also engaged in heated discussions, or rather, simple consultations, far away from Base Zero.

Many experts and scholars woke up to the holographic projection in front of them at this time, and carefully recorded the details and data about the assembled engine.

And the experts who were surrounded by them looked like young people.

Because of the further maturity of genetic MRI technology, the appearance of human beings can no longer judge the age, but judging from his demeanor, he is a young man.

"Regarding the conception of engine number 15, it is ...... as follows"

"In fact, we have obtained a large number of blueprints for the design of the light-speed engine, which can already be designed by humans in engineering theory."

"But our relevant materials have not been up to the requirements, so there are no theories and drawings but can not be realized, which is also a kind of shortcoming!"

"But not long ago, my breakthrough in new materials in the Materials Research Institute increased the strength of the original core part by more than 3 times, so I have the No. 15 engine in front of me."

"It can achieve an estimated speed of 65%-70% of the speed of light in simulation tests, which is more than twice as fast as the engines carried by today's spacecraft, and it is basically capable of traveling across star systems."

Now assembling the engine in a fully automated workshop turns out to be a completely new engine made by humans, and its theoretical speed allows humans to step into a stellar civilization with half a foot!

Think about the primitive era of human beings, our ancestors set foot on almost all the continents on the Blue Star by walking and simple tools, and now human beings will step out of the solar system and spread the fire of civilization to a farther and broader universe.

"Professor Li, how did you discover the order of atoms in this new type of material?"

"Most of this atomic structure is a step-by-step experiment, and of course, the irregular trajectory of the atomic structure in the internal journal of the base, and the important logical link of the atomic structure for the composition of molecules, these two papers also inspired me a lot."

The research institutes in Base Zero are the most cutting-edge of the cutting-edge, and everyone needs to pay attention to each issue of the journal, otherwise it will be difficult to move forward behind closed doors.

However, if the regular journals of Base Zero are lost to ordinary scientific journals, I don't know how many subversive results will be obtained.

"I see!"

The professor who had questioned him earlier suddenly realized that he also had an impression of the papers in those two journals, but he didn't think much of it at the time, which made him have to admire the young man's talent.

The rest of the experts and scholars also had mixed reactions, but the admiration was not hidden at all.

The scientific research ability in Base Zero is your pass, as long as you have enough ability, you can even connect with Lu Yu and let him give you a part-time job.

In between conversations, one of the core components of the engine has been assembled in the automated assembly shop.

There are also dozens of automations in China that support this manufacturing task, and then send the parts here for final assembly.

It will be the engine of the small ship, which will leave the Blue Star to reach the dock at the Lagrange point.

The small ship is disassembled into the components of the spaceship, and the engine will be the most important test site for the new spaceship.

In space, we can really test the speed that this engine can achieve at full power.

As long as you are in space, you dare to go all out and let the engine run at full power.

Now, dozens of large factories are working at the same time, and the entire process of building the ship's vital engine and launching it into the air can be completed almost in a week.

Such a speed can once be the world's aerospace industry practitioners have left tears of envy, and at the moment when China is presiding over the global order, it has begun to draft a space elevator plan, when the space elevator is completed, it will step into the national space era, and everyone goes to space as easy as taking a high-speed train.

That kind of picture is all on the premise that humanity will resist the unknown fleet, and a group of experts look at the core components that have been assembled in the workshop, and they will not doubt that humanity can have such a future.

Engine 15 is just one step, the next step is the lightspeed engine!
