After a while of discussion, there was a precedent of the glitzer civilization, and people were very wary of this kind of cosmic businessman, even if they got a little benefit at the beginning.

The so-called heart of defending people is indispensable. Many soldiers have put on power armour and stand on their posts to prepare for accidents.

Some people also think that this civilization may be the enemy of amoeba. They deliberately rob here and ruin the reputation of amoeba civilization. Anyway, there are countless conspiracy theories. No matter what happens, it's possible, isn't it?

After a long discussion, many people still think that this opportunity should not be missed. As long as people are careful enough, there will not be any safety problems in theory through electromagnetic wave communication.

Even if the other party gives some fake technology, what about fake information?

Even if it's fake information, it's better to have a little real content in it than none at all.

Zhang Yuan listened to the discussion and said slowly, "what kind of information do you want to trade? We must not expose the fact that we are a rookie civilization, otherwise we will suffer a small loss, and the insecurity caused by it will be a major event.... "

Because the distance between the two sides is still far, it may take seven hours for information to come back and forth. So in order to ensure smooth communication, the amount of information should be as much as possible.

All of them hesitated for a while, and soon chose to turn away from the guests and talk to each other.

"Amiba civilization, Hello, we have a lot of common knowledge about cosmic civilization, including the specific history of lower civilization and some trends of higher civilization, as well as knowledge about biology, sociology, mathematics, physics and other aspects. Which do you want to trade? What price would you like to pay? "

“…… We are looking for knowledge about curvature engine. If your civilization is willing to trade this knowledge, we are willing to pay a high price... "

The reason why people want curvature engine technology is that this technology, in theory, is the dream of low-level interstellar civilization. The technical level of Kunlun Mountain is just the peak of the second level civilization, which is much higher than that of the earth civilization, but it is a little far from the fourth level civilization.

As for The technology "consciousness uploading" of the six levels of civilization beyond civilization itself can not be used for war.

Therefore, in the face of this suspicious "advanced civilization", human beings still hold a skeptical attitude.

After sending this message, people began to wait anxiously again.

Seven hours is short, seven hours is long

A lot of people are talking about what this deal needs to focus on.

According to the existing information analysis, the vast majority of civilizations will be stuck in the level of secondary civilization.

Just like human beings, all the fish that can be caught are caught, and the rest are big fish that no one can catch.

The three-level civilization should be about the exploration of sub atom, life science, nano robot and space science. Human beings are still in a very naive state, even at a loss. The most troublesome thing in the universe is not the difficulty of technological development, but the lack of discovery.

Inexplicably, among all kinds of discussions, the ship became a little suspicious.

Because it doesn't look as tall as expected. First of all, it's the structure of the star ramjet engine. It seems that it's just the technology of the third level civilization If there's curvature technology, what do you want with ramjets? No matter how advanced it is, it is only working fluid propulsion.

"This dark spaceship, it says it is the information transfer station of amoeba civilization, is it? Who knows if it's bullshit? Maybe it's a stuck vegetable chicken civilization, cheating here! " A young man named Rambo is making his point.

One of the professors shook his head: "Mr. Rambo, I think that even if a spaceship has the technology of curvature navigation, it still needs this kind of working fluid engine as an auxiliary. Curvature navigation may have some limitations, unlike the working fluid engine. So, even if there are three levels of civilization technology, you can't deny that it is a higher level civilization. "

That's true.

"This ship sent out this message after we used the flare Very suspicious. If we don't use flares, don't we send them? Is it going to be a road robbery or something? "

“…… If they are found, they will be merchants, but if they are not found, they will be robbers? "

Zhang Yuan frowned. The conspiracy theories put forward by those people made people panic, but there was some truth in what they said

But if the other side is really not amoeba civilization, only one spaceship can carry out robbery?

"Even if the other side launches an attack, as long as it does not destroy all the human spaceships at one time, it will inevitably suffer from the crazy counterattack of human beings. No one will survive in this starry sky There is no reason to do such a thing. "

"And what can the other side get when they attack Nothing but a pile of interstellar rubbish. "

All kinds of confused guesses made my head ache.Zhang Yuan shook his head: "we do not have substantive contact with each other. As long as we are not stupid enough to say that we have any high-dimensional fragments and consciousness upload technology, there should not be too many problems."

As for curvature navigation, it's really a technology that people are eager for, which means that it can break through the barrier of light speed, but people don't expect much.

At present, it is quite convenient to rely on cosmic strings for gravitational acceleration, but there are still some limitations. It is impossible to break through the speed of light for the navigation mode relying on kinetic energy, and the route can only be limited to a small area around the cosmic string.

In fact, according to the estimation of experts, it is limited by material technology, escort technology and communication. If it is a spaceship fleet, accelerating to 10-15% of the speed of light is almost the limit. If it is a planet, it can accelerate to 30% - 40% of the speed of light.

But the use of curvature navigation, means that 10 times, 20 times faster than the speed of light navigation, no longer limited by the cosmic string, that is the real freedom!

In fact, this is just a piece of rubbish. Which civilization around the cosmic string that uses the cosmic string for navigation does not want to obtain real curvature technology?

Zhang Yuan didn't expect to get qusu technology. He just said it casually.

As time goes by, everyone is anxiously waiting, waiting

The other side's response appears!

"Hello, unknown civilization. We will analyze the authenticity of the information you sent. If it is really valid information, we will convert it into a certain amount of amoeba points. You can use these points in the amoeba market, or you can buy our information and technology in turn. "

"As for fairness and justice, please do not doubt the integrity of amoeba civilization accumulated in the galaxy for thousands of years. "

" as for curvature engine technology, it belongs to four level civilization technology, which is not included in this transaction for the time being. Please go to the amoeba market to seek relevant transactions. "

Below is a table of information prices.

Such as first level information, second level information, third level information, fourth level information and so on. Because information is valuable only if it is unknown, and it will not be valuable once it is known, so the conditions of judgment are very vague, and there is no very clear qualitative standard at all.

Many people immediately yell, which is too bullying!

Zhang Yuan's brow wrinkled, that is to say, the pricing power is completely in the hands of the other party?

Rely on the integrity of the other party?

However, there is no way to do this. Even if human beings bargain, what about the pricing power?

First of all, let's not talk about whether the other party agrees or not. People nowadays lack common sense in this respect, and it's impossible to trade fairly and reasonably Human beings don't even know what they want.

Col. Guo, who is in charge of the military direction, suddenly said, "I think we can exchange some information and test each other. It's nothing to lose a little. "

"For example, what is the so-called amoeba integral, a universal currency in the universe? So how to design anti-counterfeiting, how to have a higher degree of identification Anyway, it's better than giving up this deal. "

Zhang Yuan nodded, which is what he thought

What is the currency of interstellar civilization? It can't be paper money. Is it a digital currency with a password It's still a bit far fetched. Let's not talk about whether this kind of password can be broken or forged. How can we ensure that these passwords are amoeba points? Maybe they are made up in a random way. How can we judge the amount of money?

Or the bitcoin mode of networking, which can guarantee authentic anti-counterfeiting, but human beings have no network between interstellar civilizations.

"If there is a network between interstellar civilizations, it's not bad. We can take this opportunity to connect."

"Don't think too much! It's going to have to go faster than light. "

After a while, everyone calmed down.

But what kind of message does it send? What do humans have?

There are many things that human beings have, but for the sake of safety, many of them can not be exposed, such as their birthplace, the scientific and technological strength and military strength of the whole fleet, and so on.

"Or send a copy of the structure of the helium hydrogen ion gun?"

As a variety of ion gun, helium hydrogen ion gun can only be installed in a large spacecraft. In fact, the theory is not difficult, the main problem is the material.

Zhang Yuan shook his head. "There's no need. Maybe through this kind of structure, the other party can infer our scientific and technological strength and material level. What if the other side has the ability to miniaturize this weapon? No doubt it's the act of teaching others how to teach others. "

Li Zhendong asked: "or send some conventional scientific and technological materials to test It's just conventional technology anyway. "

By the way!

There was a flash of inspiration in Zhang Yuan's mind."We can send some messages to test whether the other party is an amoeba civilization..."

He typed in a text on the screen: "Dear amoeba civilization, we know that the Gaowei prison on ETA has exploded, and a large number of super life have taken the opportunity to flee. ETA, the AI manager of η Gaowei prison, has issued a warrant for the pursuit of these super life. If the super life escapes, it will be rewarded by Gaya civilization. "

"Please evaluate the value of this message."
