After a while, katolanpus-3 sent some information: "this is the price table of these years. Because the trading market is about to dissolve, prices are constantly changing, most materials are becoming cheaper, and military resources are becoming expensive."

Zhang Yuan's heart moved. Are all kinds of military resources becoming expensive?

"... these are the list of conventional technologies, including some conventional technologies required by level IV civilization. You can buy directly from the trading market at a slightly higher price, but the quality is guaranteed; You can also buy from other civilizations and let the interstellar trading market act as an intermediary platform. Our civilization only charges some handling fees... "

"You can also sell technology to other civilizations and the interstellar market to get amoeba points. Jihaman civilization is a five level civilization. If you have science and technology that your civilization has never mastered, you will get high rewards. "

There are 1500 points in people's hands, neither too much nor too little. They can barely afford some science and technology of level Four civilization.

"We can sell new civilization historiography!" A young scientist had a whim.

People are also prepared in this regard. It would be good to sell the knowledge of one or two thousand points here again.

After some sorting, people passed some materials of new civilization history to the past and asked the other party to make an evaluation.

"Sorry, we already have this information."

Zhang Yuan thought carefully and understood that the technology of the whole amoeba faction should be interconnected. Because humans have been sold in another trading market, they can't be sold for the second time in this market.

Of course, mankind can sell the history of new civilization to other unwitting four civilizations.

However, the discipline of new civilization history is sometimes very effective, but it is actually useless for most civilizations. Because for any civilization, action is often more important and difficult than theory.

The social structure, ideology, culture and history of each civilization are very different. Copying human beings is a dead end. Therefore, some civilizations that know goods think it's great and a good subject. More civilizations that don't know goods think it has no use value. It's like a castle in the air. It's difficult to sell it at a good price.

Zhang Yuan said: "after this knowledge is sold, it will not do us much damage, but if it is sold cheaply, it is not appropriate to ruin the street."

"Yes!"

"That's it..."

Foreign Minister Lao Yang pondered for a while and said, "the most valuable technology we can sell is additional perception. We go to aliens and try to sell things in this regard. "

A serious extra perception, more than 10000, less than 7000 amoeba points. TOS civilization is almost stripped away by humans for this thing.

Although they only paid 1500 points, they gave most of the core technologies to humans, and they were still very happy to die.

Therefore, after eating the technology accumulated by the TOS civilization for tens of thousands of years, the inside information of the new human civilization suddenly rises, and there is no need for the technology of other three-level civilizations.

And Lao Yang wants to repeat the old trick and find some wronged big heads.

Making ten thousand dollars is the real level Four civilization!

There are more than 81000 interstellar civilizations in this place. Isn't there a species similar to the TOS civilization?

Everyone looked at Yuan Chang, and he has the final say in this matter.

Zhang Yuan waved his hand and said with a bitter smile, "Mr. Yang, you think about this thing too simply. Don't be too optimistic first. The individual brain structure of each civilization is completely different. Every additional perceptual development is equivalent to starting from scratch. There is no guarantee. "

"Of course, we have trained a group of excellent talents and accumulated a lot of experience. As long as we don't have a very strange brain, we should be able to do it in 40 or 50 years. Oh, there are also some preconditions. This civilization must have more powerful programmable assisted brain technology, otherwise it can't be transformed... "

"The most important thing is that this civilization should fully trust us, provide enough biological samples, and especially hand over its brain transformation technology to us."

"We also have to bear the risk of using virtual world technology... More use, but also the risk of exposure."

"If you can handle all this, there should be no problem on our side."

Lao Yang frowned. These are troubles, big troubles.

Finally, he clapped his hands and said, "don't worry about this. We are still measured and won't shout everywhere. Not really. We can also sell some scientific papers in this field. It's pretty good just to form extra colors in the brain. "

"Anything related to intelligence is extremely expensive. Don't worry about finding a buyer..."

"My biggest worry is that the trading market will move in 20 years. Do we have enough time?"

"No, no, no, you have to worry about another point!" An expert in the field of security has great differences in this regard: "such papers are sold more and have an impact on the security of human civilization itself. You know, extra perception is our unique technology. Even some old tier four civilizations can't compare with us. "

"Even if we put aside the virtual world, it will arouse the covet of other civilizations."

"We are all level Four Civilizations. What are we afraid of?"

During this conversation, the territory of new human civilization arrived, which was a bare metal plain without any buildings.

The spaceship on which man himself rides can only be used as a temporary embassy.

Zhang Yuan couldn't help sighing: "in the future, we will transport some construction machines from the rear base camp to build a truly magnificent embassy."

"I'll inform you right away."

As a result, the first hour after the establishment of the Embassy of the new human civilization, an alien civilization came directly to the door!

It is a "Galactic curvature science and Technology Standardization Organization", whose main purpose is to sign the next curvature science and technology non-proliferation treaty with the new human civilization.

"... young new human civilization, Hello, welcome to the palace of level 4 civilization. First of all, like self introduction, we come from the quadrilateral civilization. We are one of the main members of the Galactic curvature science and technology research organization. We are a civilization with a history of 200000 years. "

"This organization focuses on curvature technology and various space technologies, and signs a curvature technology non-proliferation treaty with each other."

This quadrilateral civilization alien looks like a black stone, four or five meters high.

Instead of entering the human embassy, it stayed in its own spacecraft and communicated with humans through electromagnetic waves.

"NPT?" Zhang Yuan's expression moved, thinking of some things he met when he was in the Huantai civilization trading market.

It seems that he saw the doubts of mankind. The stone man continued: "... You know, the biggest difference between class IV civilization and class III civilization is curvature technology. It is an earth shaking qualitative change from the military and transportation levels."

"Our convention organization was linked by a five-level civilization millions of years ago. Its purpose is not to prevent the three-level civilization from acquiring curvature technology, but to promote the peaceful development of the galaxy. We just hope that the four civilizations will not simply give them science and technology directly. "

"... giving curvature technology directly does not make much sense, and will cause chaos in the galaxy and trigger various contradictions and conflicts."

The reasons for this are very complex. First, the most important thing is to ensure the advantages of level Four civilization, and second, to ensure the stability of the situation in the galaxy.

Because it's too easy for the fourth level civilization to escape. If this technology is bad, the situation in the galaxy will become extremely unstable.

"... only five civilizations have directional superluminal communication and sufficient strength to block a space. Even the fourth level civilization has no good way to pursue warp speed. "

"Please think about it. Once this technology is widely spread and primary and secondary civilizations can also have it, what will they think?"

"Their other technologies are poor, but with warp speed, will they risk plundering other civilizations to obtain rapid improvement? Attack is always simpler than defense. First class civilized nuclear weapons can still cause damage to our spacecraft. I think you should know that. "

"If the form of the galaxy becomes extremely chaotic, how can the interstellar trading market continue?"

"The communication between civilizations will also become more difficult, not simpler. Any real fourth level civilization, through tens of thousands of years of development and long historical experience, knows that it is not easy, but does the first level civilization know? They won't know, and it's hard to have such a history. "

"Some civilizations have not even unified the countries on their own planet and are still in a state of dictatorship."

"Once there was a galaxy where the warp speed was greatly spread, resulting in a large number of wars, slavery and slavery. Those indigenous civilizations in remote areas that have not yet stepped out of the planet cannot develop at all. "

"This is another kind of injustice."

Zhang Yuan has to admit that what the stone man said seems reasonable... But it's a little strange. Is the fourth level civilization very moral and the lower level civilization has no morality?

In a word, it is to ensure your own advantages.

The stone man added: "our treaty stipulates that... The value of any clue about curvature technology is 10000 amoeba points, and the value of complete curvature technology is 100000 points. This is the standard price set by this organization. As long as you don't sell at a low price at will and disturb the prices. "

After signing the relevant treaties, the organization will give away some knowledge about curvature free of charge. Of course, it will not be any particularly profound knowledge. It is just some ordinary things, but it can be regarded as good knowledge for human beings who have preliminarily entered the fourth level of civilization.

On the other hand, if human beings want to obtain higher-level space technology, it will be cheaper to buy it in this organization.

"We have another question..."

A human diplomat seemed to think of something and asked, "what kind of punishment will we receive if we violate this Agreement and teach this technology to other civilizations?"

The stone man said with deep meaning: "if you secretly violate and are not known by any other civilization, there will be no punishment..."

"But if you are known by other civilizations, you may lose the friendship of other civilizations... And all the trading markets of the amoeba faction will deduct the goodwill of your civilization."

"However, even if it violates the relevant treaties, we have no force to threaten your life. Please rest assured."

I see. Zhang Yuan nodded. This treaty may have been made by the amoeba faction.

It has been discussed for some time. It is generally believed that curvature technology is the core technology of new human civilization after all, and it is impossible to blindly give it to low-level civilization. Since it is the regulation signed by most four civilizations, there are not too many side effects and nothing to avoid.

The other party said, "please tell us the specific reason for obtaining curvature technology. Just state it briefly. We need to track and understand the approximate source of warp speed for any civilization. "

The collision between the two neutron stars was described, about 400 light-years away. In order to reduce trouble, he also described that he had an ally. Of course, he didn't say the name of "TOS civilization".

The other party seemed to suddenly realize, "I see. We observed this neutron star collision. According to previous data, it was indeed detonated in advance! So I can make a job. "

Just as the alien spacecraft was about to slowly fly away, people soon stopped him. Because this guy looks lively and doesn't speak coldly like the big bug of jihaman civilization. It would be nice to ask for more information.

"This... Sir, we still have some questions to ask you. Are you free?"

After pondering for a while, the stone man replied, "Oh, my time is very limited... What else does your civilization want to ask?"

"About the owner of Dyson ball, tabby civilization. This should be a very powerful civilization. We are interested in the master ship of Dyson ball... What do you know? "

The other party immediately replied: "we don't know much about the Tabi civilization. It has been a long time since the disappearance of the Tabi civilization. The last subsidiary civilization of the Tabi civilization also disappeared 150000 years ago. In the A-1 area, there is an artificial intelligence 'Omega' left by the Tabi civilization, which is responsible for the engineering construction of the whole Dyson ball. "

"If you are interested, you can consult your assistant and go to area A1 for more information. I'm sorry, I have to report to the superior department as soon as possible... "

With this sentence, the guy quickly opened the ship and ran away.

"What an anxious civilization!" Zhang Yuan shook his head

If you consult through "katolanpus-3", you will find that the self introduction of quadrilateral civilization is "acute lattice" and "single process".

The so-called "single process" means that you will not do the second thing until you finish one thing.

In fact, human beings are also single process creatures, but human beings have a bad habit. They always want to use one heart and two purposes, and often wander.

Zhang yuanluewei can imagine that the internal situation of this civilization, quadrilateral civilization, is normally orderly and full of order and rules.

"Four levels of civilization, indeed, has its own advantages."
