Start sweeping the universe by rubbing the CPU with your hands.

Huo Xiyu obviously meant that he gave up on a major matter related to the fate of civilization just because of a mere emotion. This should not be done by a high-level civilized person like Lu Xinghe.

Lu Xinghe said calmly: "From the perspective of us humans, maintaining the dignity of civilization is the greatest benefit."

Huo Xiyu said no more. After a moment of silence, he stood up and bowed slightly to Lu Xinghe through the glass: "Your Excellency Lu Xinghe, I would like to apologize in my own name and in the name of the head of Luotu civilization for my previous rude behavior towards you.

sorry. "

Lu Xinghe solemnly said: "I accept your apology."

Huo Xiyu said: "Now, everyone with knowledge of this matter already knows that Mr. Lu Xinghe terminated this negotiation because of our impolite behavior.

This space carrier is indeed a cargo ship. No other senior management knows about my arrangements here. This is the place where secrets can best be kept, so you can tell us what you humans are planning. "

Lu Xinghe's heart moved.

From this point of view, President Huo Xiyu's insistence on not apologizing does not seem to be that simple.

In the beginning, it was probably because of emotional factors. But later on, he took advantage of the situation and deliberately took advantage of this matter to send a signal to the outside world that the negotiations were terminated. Then he appeared here unexpectedly.

In this way, leaks will be prevented to the greatest extent.

But this is all in the past, it doesn’t matter anymore.

Lu Xinghe said in a deep voice: "As you can see, our human civilization is suffering from the same predicament as your civilization at the moment. You cannot be promoted to a sixth-level civilization, and we are also unable to be promoted to a fifth-level civilization due to external factors.

Our civilization is seeking to advance to level five, and in the future level six. Your civilization is currently seeking to advance to level six. We have the same interests and naturally have a basis for cooperation. "

"Promoted to level six, and promoted to level five, huh..."

Huo Xiyu sighed.

His meaning was clear.

Can these two things be confused? Can two ants compete for a crumb of bread, and two major companies compete for hundreds of millions of dollars in profits, be the same thing?
Lu Xinghe said calmly: "The essence is the same."

Huo Xiyu said: "Drag our Luotu civilization into the water and make us fail in the lawsuit. Is this your plan? The purpose is to make me recognize the reality? What a good method."

"The reality is there. It is better to wake up early than to wake up late. Besides... this can probably be regarded as a show of strength. If we humans have not shown the ability to plan certain things, I believe that the Head of State will not give me and you Opportunity for an interview?”

Huo Xiyu did not hide it, but admitted generously: "It is indeed true. Then, let me see your strength."

Lu Xinghe said: "We need to make one thing clear first. If you stay within the Silver Alliance system, your civilization will have no hope of promotion."

Huo Xiyu whispered: "I used to have some illusions. Now... I have to admit that what you said is right."

"The hope of promotion to level six civilization lies outside the Silver Alliance."

Huo Xiyu suddenly raised his head and stared at Lu Xinghe with two sharp eyes.

"I knew you humans were brave, but I didn't expect you to be so brave. Leave the Silver Alliance, oh, leave the Silver Alliance..."

Lu Xinghe was not afraid at all and looked directly at Huo Xiyu.

Huo Xiyu lowered his voice, which was full of solemnity: "If your human plan is just like this, then there is no need to say it! You can't be promoted within the Silver Alliance, and you can't be promoted outside the Silver Alliance! The Greenoka civilization has gone through millions of years of development. There’s no time for promotion!”

“Although we humans are only a fourth-level civilization, we can also make certain guesses about the promotion method of a fifth-level civilization.

If our prediction is correct...the key to advancing from a fifth-level civilization to a sixth-level civilization should be the observation of certain special physical processes that occur in the natural environment, right?
However, this kind of physical process is relatively rare in the Milky Way. In this way, the sixth-level civilization only needs to block these locations to strangle the promotion channels of the fifth-level civilization, right? "

Huo Xiyu admitted again: "Yes. The key to promoting a fifth-level civilization to a sixth-level civilization lies in the birth process of a macroscopic black hole. It must be observed closely. Only in this way can enough data be collected."

"Oh, in this case, there are only certain types of supernova explosions and neutron star mergers.

Throughout the universe, supernova explosions can be observed approximately three to four times a day. When the scope is reduced to the Milky Way, the number is much smaller, about once every one hundred years on average.

The number of neutron star mergers is much less than the number of supernova explosions and can be ignored.

In this case, there will only be one hundred observation opportunities within ten thousand years. With the strength of the founder civilization, there is no pressure at all to dispatch fleets in advance to guard these stars that are about to explode as supernovas to avoid being closely observed by any level five civilization. "

Huo Xiyu said: "This phenomenon of macroscopic black holes merging into larger black holes is also possible. However, the frequency of black hole mergers is lower than that of neutron star mergers and can be ignored."

"Can't a black hole swallow other stars?"

"The swallowing rate is too slow and the mass growth is too slow, it won't work. Unless it is a black hole swallowing a neutron star, but there are strict limits."

"I understand. In this case, as long as you are still in the Milky Way, no matter whether you break away from the Silver Alliance or not, there is no hope of promotion... No wonder the founder civilizations are so confident..."

Huo Xiyu snorted: "So, what plans do you humans have that can bring us hope of promotion?"

A smile appeared on Lu Xinghe's face: "If it doesn't work within the Milky Way, what about outside the Milky Way?"

An angry look appeared on Huo Xiyu's face immediately: "What nonsense are you talking about? Who doesn't know that the tentacles of the founder civilization cannot extend to extragalactic galaxies? Who doesn't know that as long as we can reach extragalactic galaxies, we can observe the birth process of black holes without any scruples?

But, what’s the use of knowing? Even the tentacles of the founder civilization cannot extend to the extragalactic galaxy. How can a mere fifth-level civilization reach the extragalactic galaxy? "

Lu Xinghe said: "From your perspective as a fifth-level civilization, what is the reason why even a sixth-level civilization cannot reach extragalactic systems?"

Huo Xiyu snorted again: "Of course it's the distance.

Even the closest satellite galaxy to the Milky Way, the Canis Major Dwarf Galaxy, is 2.5 light-years away from the Milky Way from its closest point. "

"At the speed that the most advanced six-level civilization spacecraft can reach, calculated at 1000 times the speed of light, it only takes 2.5 years to sail these 250 light-years. This seems like nothing." "There is no supply."

Huo Xiyu shook his head again: "The interstellar space is too empty, and super-light navigation of 1000 times the speed of light requires too much energy."

Lu Xinghe pondered: "In this case...why don't level six civilizations consider remote control and launch some unmanned machinery or spacecraft to satellite galaxies? There is no doubt that the energy consumption and quality of unmanned spacecraft are lower than that of manned spacecraft. many."

Huo Xiyu said: "It's still an energy issue. Even an unmanned spacecraft needs to carry energy. And, the more energy and the greater the mass, the greater the energy required to travel faster than light speed.

This is a simple mathematical problem. A simple calculation can show that unless there is a technological breakthrough, even if you carry the mass of the entire universe as an energy reserve, you will not be able to reach the Canis Major dwarf galaxy. "

Lu Xinghe pondered: "Is it feasible to collect materials from star streams as energy?"

The so-called star stream is a phenomenon in which the gas, dust and other materials in the satellite galaxies of the Milky Way flow toward the Milky Way like a river under the influence of the Milky Way's gravity.

"It's not feasible. The density of star stream material is too low, even compared to the density of interstellar dust in the open areas of our galaxy. How is it possible to collect enough energy?"

"Then...there is only one last option left. Is it feasible to adopt conventional navigation? Conventional navigation can rely on inertial navigation and basically consumes no energy.

For example, directly send an unmanned spacecraft, directly accelerate to 0.9 times the speed of light, and make it fly to the Canis Major dwarf galaxy in a regular navigation mode. It's nothing more than a flight of more than years. Your Luotu civilization has a history of hundreds of thousands of years. It seems worth waiting for more than years for the hope of advancing to a sixth-level civilization. "

Huo Xiyu's tone was a little unkind: "If you humans are just fanciful and speculate on the behavior of advanced civilizations based on the technological level of your own fourth-level civilization, then I don't think there is any need to continue this negotiation."

Lu Xinghe insisted: "Please tell me why it's not feasible first."

Huo Xiyu said coldly: "You probably don't know that the basic principle of long-distance communication, the underlying physical basis, is a certain effect of manifest matter and dark matter.

Although the dark matter halo of the Milky Way covers the Canis Major dwarf galaxy, there is only very little apparent matter in the empty area of ​​more than 20,000 light-years between the two galaxies.

This effect is too weak to support communication over long distances.

In other words, once it leaves the galaxy, the unmanned spacecraft will lose contact with the controlling party.

Flying solely relying on preset programs for more than 20,000 years without human control? Even the sixth-level civilization can’t do it, let alone our fifth-level civilization.

Besides, even if the flight finally arrives, so what? Simply rely on preset programs to collect data on your own from more than 20,000 light-years away?

Even if the data collection is completed, the relevant information cannot be sent back at all. Unless it returns on its own under the control of the preset program.

The entire process lasted more than 60,000 years. Relying on preset programs to run on their own for more than 60,000 years? impossible. "

Lu Xinghe sighed: "I see, it is indeed so. Although President Liu Yuan has guessed that there must be some kind of restriction that prevents level five or level six civilizations from carrying out any form of cross-river navigation, he did not know about this What exactly are the limitations.

Now I know that this is the case.

But... if I say, we humans have some way to launch multiple unmanned spacecraft and related scientific research facilities, sail to the Canis Major dwarf galaxy through conventional navigation, and complete data on the birth process of the black hole there. Collect, and then fly back by regular sailing to bring these data back so that the fifth-level civilization trapped in the Milky Way has the hope of being promoted to a sixth-level civilization... Are you interested, head of state? "

Huo Xiyu was suddenly shocked. After a long while, he exhaled lightly and shook his head: "You humans can't do it."

"It is true that we can't do it now. However, after being promoted to a fifth-level civilization, there is hope that we can do it. And if we want to be promoted to a fifth-level civilization, we must first break away from the Silver Alliance. Just like your civilization wants to To be promoted to a sixth-level civilization, you must first leave the Silver Alliance."

Before Huo Xiyu could speak, Lu Xinghe continued: "Let's not discuss the possibility of our human civilization achieving this for now. Let's assume for the moment that it is true. Then, if it is true, what will you do, head of state? choose?"

Huo Xiyu said coldly: "It turns out that your real purpose is to use the power of our civilization to break away from the Silver Alliance."

"Indeed."

Lu Xinghe admitted frankly: “In the process, it also helped your civilization break away from the Silver Alliance and gain hope for promotion.

I said from the beginning that this is cooperation, a cooperation that seeks common interests. "

"So, your complete plan is to use our power to help you break away from the Silver Alliance, and then you will help us break away from the Silver Alliance. After both of us break away, and when your human civilization is promoted to a fifth-level civilization, you will adopt that routine Navigate to the Canis Major dwarf galaxy, wait tens of thousands of years, and bring back the data on the birth process of the black hole, so that everyone can advance to a level six civilization?"

"Yes."

Huo Xiyu sneered: "It's so easy to break away from the Silver Alliance... Our civilization can't even break away. How can we help you break away?"

"Don't talk about us for now, just talk about your civilization."

Lu Xinghe raised a question: "As far as I know, the Milky Way is vast and there are too many places that the founder civilizations cannot cover.

It is very simple to leave the Silver Alliance. You can just take a spaceship and leave. Can the Silver Alliance also monitor the course of each of your spaceships? "

"Civilization migration can't be so simple."

Huo Xiyu said coldly: "With a population of one trillion, how many spaceships and supplies are needed?
Calculated in hibernation, a large space carrier can accommodate up to about 100 million people. This is a 10,000 large space carrier.

In order to transport supplies, our civilization needs to start a large-scale material reserve plan and carry out large-scale production for at least a hundred years.

In order to ensure that civilization will not perish due to lack of energy after arriving at the destination, we also need to build a large number of bases at the destination in advance and carry out environmental transformation at the level of the entire galaxy.

This in turn involves a huge amount of manpower and material transportation.

How could the entire relocation plan be kept secret with such a huge amount of work? I'm afraid it was noticed by the founder civilization from the beginning. "

He was already a little impatient at this moment. Because he felt that the human in front of him was always talking about some very ridiculous plans and asking some very untechnical questions.

But Lu Xinghe saw a smile appear on his face again: "What if I said that we humans have the ability to allow you to go into battle lightly, without any preliminary preparations, just transporting people?" (End of Chapter)
