Everyone discussed for a while, and with the precedent of the Gliese civilization in the past, people were still very wary of this kind of cosmic merchant, even if they got a small benefit from the beginning.

The so-called defense of people is indispensable, and many soldiers have already put on power armor and stood at their posts, ready for accidents.

Some people also think that this civilization may be the enemy of amoeba, deliberately robbing here and ruining the reputation of amoeba civilization, anyway, there are countless conspiracy theories of all kinds of nonsense, and anything can happen, isn't it?

After discussing for a long time, there are still many people who believe that this opportunity should not be missed, as long as people are careful enough to communicate through electromagnetic waves, there will be no safety problems in theory.

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

Even if it's false information, it's better to have a little truth in it than nothing at all.

Zhang Yuan listened to everyone's discussion and said slowly: "What kind of information do you want to trade?" We must not expose the fact that we are rookie civilizations, otherwise the loss is small, and the insecurity caused is a big thing......"

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

Everyone hesitated for a while, and soon chose to be anti-guest, and in turn to talk to each other.

"Amoeba civilization, hello, we have a lot of common knowledge about cosmic civilizations, the specific history of low-level civilizations and some trends of high-level civilizations, as well as knowledge about biology, sociology, mathematics, physics and other aspects. Which one would you like to trade? What price are you willing to pay? ”

“…… We're looking for knowledge about the curvature engine, and we're willing to pay a dearly price if your civilization is willing to trade that knowledge......"

The reason why people want curvature engine technology is because this technology is theoretically something that low-level interstellar civilizations can only dream of. The technical level of Kunlun Mountain is only the pinnacle of the second-level civilization, which is much higher than the technology of the earth civilization, but it is a little far from the technology of the fourth-level civilization.

As for...... The sixth-level civilization technology "consciousness upload" that is beyond the civilization itself cannot be used to fight wars.

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

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

Seven hours is a short time, and seven hours is a long time......

Many people are discussing what to focus on in this transaction.

According to the analysis of the existing information, the vast majority of civilizations will be stuck at the level of second-level civilizations.

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

The third-level civilization should be about the exploration of subatomics, life sciences, nanorobots and space science, and human beings are still in a very naïve state, and it can even be said that they are at a loss. The most troublesome thing in the universe is not that technology is difficult, but that there is no development discovery.

Inexplicably, in the midst of all the discussions, the ship became a little suspicious.

Because it doesn't look as tall as it seems, first of all, it's the structure of an interstellar ramjet engine, which seems to be just a third-level civilization's technology...... If you have curvature technology, why do you need to ramjet engines? No matter how advanced it is, it is only a working fluid propulsion.

"This pitch-black spaceship, it says it's an information relay station for amoeba civilization, is that what he is? Who knows if it's? Maybe it's a rookie civilization that has been stuck, and it's scam here! "A young man named Rambo is expressing his opinion.

One of the professors shook his head: "Mr. Rambo, I think that even if a spaceship has the technology to travel with curvature, it still needs this kind of working engine as an aid. Curvature sailing can have certain limitations and is not as freewheeling as an industrial engine. Therefore, even if the technology of a third-level civilization appears on it, you cannot deny that it is a more advanced civilization. ”

There is some truth to that.

"This ship didn't send this message until we used a flashbang...... Very suspicious. If we don't use flashbangs, don't we send them? Will there be some roadblocks and robberies? ”

“…… If you are discovered, you are a businessman, but if you are not discovered, you are a robber? ”

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 party is really not an amoeba civilization and only has a spaceship, can it also carry out robbery?

"Even if the other party attacks, as long as all the human spaceships are not destroyed at one time, they will inevitably suffer a crazy counterattack from the human race. When the time comes, no one will survive in this starry sky...... There's no reason to do that. ”

"And what do you get by attacking the other side...... I won't get anything but a bunch of interstellar garbage. ”

All kinds of messy speculations have caused headaches.

Zhang Yuan shook his head: "We don't have substantive contact with each other, as long as we are not stupid enough to say that we have any high-dimensional fragments, consciousness upload technology, there shouldn't be too many problems." ”

As for curvature navigation, it is indeed a technology that people are very eager for, which means a technology that can break through the barrier of the speed of light, but people do not expect much.

Relying on cosmic strings for gravitational acceleration is now quite convenient, but it still has certain limitations. Relying on the kinetic mode of navigation, it is impossible to break through the speed of light, and the route can only be limited to a small area around the cosmic string.

In fact, according to expert estimates, it is limited by material technology, escort technology and communication. If it is a fleet of ships, it is almost the limit to accelerate to the speed of light at 10-15%, and if it is a planet, it can accelerate to 30%-40% of the speed of light.

But using curvature to sail means that ten or twenty times faster than the speed of light, no longer limited by the cosmic strings, that is the real great freedom!

In fact, this is a complete nonsense, around the cosmic strings, the civilization that uses the cosmic strings to sail, which one does not want to obtain real curvature technology?

Whether he can get warp speed technology, Zhang Yuan doesn't have any extravagant hopes at all, but just says it casually.

As the minutes ticked by, everyone waited anxiously and waited......

The other party's response appeared!

"Unknown civilization, hello. Regarding the information sent by you civilly, we will analyze the authenticity of it. If it is indeed valid information, we will convert it into a certain amount of amoeba points, which you can use in the amoeba trading market, or you can buy our information and technology in turn. ”

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

"Regarding the technology of the curvature engine, it belongs to the fourth-level civilization technology, and it does not belong to the scope of this transaction for the time being. Please go to the amoeba trading market to seek relevant transactions. ”

Below is a table of information prices.

Like what level 1 information, level 2 information, level 3 information, level 4 information, and so on. Because information is such a thing, what you don't know is valuable, and once it is known, it is worthless, so the conditions for judgment are very vague, and there is no very clear qualitative standard at all.

Many people immediately scolded, which is really too bullying!

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

Relying on the integrity of the other party?

But there is no way to do it, even if human beings bargain, what about the pricing power that they want?

First of all, not to mention the question of whether the other party agrees, people nowadays are too lacking in common sense in this regard, and it is impossible to trade fairly and reasonably...... What exactly human beings want, even they don't know.

Colonel Guo, who was in charge of the military direction, suddenly said, "I think we can exchange some information and test the other party." It's okay to suffer a small loss. ”

"For example, what exactly is the so-called amoeba points, a universal currency of the universe? So how should the anti-counterfeiting aspect be designed and how to have a higher degree of recognition...... Anyway, it's better than giving up this deal. ”

Zhang Yuan nodded, this was also what he thought......

What is the universal currency of interstellar civilizations? It certainly can't be paper money. Could it be a digital currency with a cryptocurrency...... It's still a bit far-fetched, not to mention the question of whether this kind of password can be deciphered and forged, how to ensure that these passwords are amoeba points, maybe it's just messed up, how to judge the amount of currency?

Or the networked Bitcoin model, which can ensure authentic anti-counterfeiting, but human beings do not have a network between interstellar civilizations at all.

"It would be nice if there was a network between interstellar civilizations, and we could connect to it while we had the opportunity."

"Don't overthink it! That's going to have to be a faster-than-light network. ”

After a while, everyone calmed down.

But what exactly is the message being sent? What does humanity have?

There are many things that human beings have, but for the sake of safety, there are many things that cannot be revealed, such as one's place of origin, the scientific and technological strength of the entire fleet, and the military strength.

"Or send a helium-ion ion cannon in a way that's built?"

The Helium Hydrogen Ion Cannon is a variant of the Ion Cannon, and only bulky ships are capable of installing this weapon. The theory is not difficult, but it is mainly a matter of materials.

Zhang Yuan shook his head, "There is no need for this, maybe through this kind of structure, the other party will be able to infer our scientific and technological strength and material level." What if the other side has the ability to miniaturize such weapons? It is undoubtedly the behavior of the class to get an axe. ”

Li Zhendong asked next to him: "Or send some conventional scientific and technological materials to test and probe ...... It's just regular technology anyway. ”

That's right!

A flash of inspiration flashed in Zhang Yuan's mind.

"We can send some messages to test whether the other party is an amoeba civilization ......"

He typed a text into the screen: "Dear amoeba civilization, we have learned that the high-dimensional prison located on the η star of the ship's base has exploded, and a large number of super lifeforms have taken the opportunity to scatter and escape. Ita, the AI that manages the η High Dimensional Prison, has issued a hunt warrant for these super beings, and if they capture the escaped super life, they can get a reward from the Gaia civilization. ”

"Please evaluate the value of this piece of information."
