Because of the distance, each communication has to be transmitted for more than an hour. So for the sake of simplicity, I said it all at once.

After introducing himself directly, the other party sent a large number of chatters: "Blue Star Civilization, you are the first interstellar civilization we met in this event, and you are also a brand new customer!" ”

"So, after much consideration, we decided...... A big deal for you guys! ”

"We have various technologies at the L2, L3, and L4 levels, a large number of exotic life species, and massive material resources...... You can buy anything, you can sell anything, and you can get a big deal. Please refer to this table for specific prices......"

“…… If you feel that the price is not right, you can have a detailed discussion with us, everything is negotiable...... I hope we can build a deep friendship in the transaction. ”

In the words, the businessman seems to have a little "joy" because of the discovery of new customers, and there is a flattering statement.

Immediately after that, people received a large amount of radio wave data, and the information was encoded very routinely and was not encrypted.

After analyzing the data, the experts of the observatory found that all of the data were product information.

"Offer?" Hearing this word, Yu Yifeng instinctively brought a trace of vigilance.

This vigilance is not so much about security, but about that kind of ...... The psychology of fear of being "pitted".

"This businessman is so powerful, just a few words, it makes many people have an inexplicable good feeling."

It is deliberately showing weakness, like the kind of "surprise" that a salesman suddenly solicits business when he can't sell anything for a long time...... Coupled with what "discounts", people naturally have a psychological advantage.

This kind of psychological advantage is deliberately created by the other party.

Of course, he will not be fooled by this kind of psychological means commonly used by low-level civilizations, and it is impossible for him to be dizzy because of any discounts.

Yu Yifeng quickly stared at the form, and his heart moved slightly.

Even if there is no trading activity, this form alone is already a loss.

Through this information, the new humans can roughly estimate what the monetary unit of interstellar civilizations is.

"Assuming that this businessman really gives any preferential treatment, or plays some treacherous tricks, it will not be too different in theory. The approximate price should be accurate. Estimating with a price range of 50%-200%......"

There were many scientists in the captain's room, plus the staff scattered in various places of the Noah, and they all studied the data.

At the same time, he whispered with interest.

Sure enough, as people think, this table uses "antimatter" as the basic unit of trading.

Among them, there are a variety of trading objects, such as material, technology, biology, information and even labor, which can be traded.

A scientist converted the data in the table into units: "According to our calculation unit, 112.32 tons of antimatter can be exchanged for 1 amoeba point. ”

Yu Yifeng frowned slightly, this number is not small.

1 gram of antimatter meets positive matter, and after annihilation, it can produce 43,000 tons of TNT equivalent, and 112.32 tons of antimatter can produce ...... Nearly five trillion tons of TNT equivalent exploded.

Of course, after more than 100 years of development, there is no big problem for the new human beings to come up with hundreds of tons of antimatter.

"728,092,000 tons of helium-3, which is 1 amoeba credit." When Yu Yifeng saw this data, he felt a little pain.

700 million tons of helium-3, only one integral?

Helium-3 is a thing with an extra "10,000" in the back unit, which can't be sold for any money at all, and has purely become a kind of cheap labor.

So, the dream of buying with cheap materials is in vain.

"Again, deuterium is much cheaper...... 7,142,159,000 tons of deuterium, which can be exchanged for 1 amoeba credit...... There are also purity requirements. The scientist in charge of unit conversion scratched his head, headache over such numbers.

These things require pure substances, not just a little water that can be sold for money, but also separated and purified.

A cursory look at the past shows that basically everything is calculated by "10,000 tons".

In the case of very common materials in the universe, these things really can't be sold for money, at most they can be used as porters, selling a little "labor".

To Yu Yifeng's surprise, "tritium", "uranium" and "complex organic matter" are more valuable than ordinary nuclear fusion fuel.

However, if you think about it carefully, people quickly understand that the half-life of "tritium" is not long, it is quite difficult to produce and preserve, it is impossible to exist on a large scale, and it is normal for the price to be high; The production of "uranium" is also quite difficult, and can only be obtained in large quantities through supernova explosions, and the amount of uranium mined on each terrestrial planet is quite limited.

However, "complex organic matter" can only be produced on living planets, and artificial synthesis is more difficult and relatively "expensive". Of course, material resources, no matter how expensive, are bargains compared to the things below.

This alien commercial spacecraft does not receive, nor does it sell, these cheap things. Because the capacity of the spacecraft is so limited, if they are sold tens of billions of tons of cheap helium-3, it is impossible to put it underground......

"Understandable." Some scientists muttered to themselves: "It's good to use it yourself, but it's not good to sell it for money." ”

"I didn't see anything particularly expensive, and I didn't have a perfect vegetarian price......"

Yu Yifeng was not discouraged, but excitedly flipped the table to the next page.

"That's a lot of information!"

This page is information and intelligence on various indigenous planets. It may be that this commercial spaceship went all the way and collected it by the way. This kind of information is not particularly expensive, and it is simply written.

He didn't look much at it, and a fool would buy this.

If it was a complete map of the interstellar civilization, he might think about it.

On the next page, there are some ...... Strange creatures!

This "Libsis Civilization" proudly wrote: "We have collected thousands of powerful alien creatures, fierce and powerful, with extremely tenacious vitality!" Some of these individuals are the creative beings of higher civilizations and have very unique genetic material......

"The study of nanodynamics and gene dynamics has great reference significance. There are even silicon-based biological ......"

A large string of balabalas, somewhat interested. But at a glance, each creature needed several points, which made Yu Yifeng shake his head again and again.

No matter how strong a creature is, a nuclear bomb will kill it. Genetic material, special nanodynamics, gene dynamics templates, there is some value.

But a few points...... It's too expensive, right?

"Even if it's a rare silicon-based creature...... It's not worth the price either. ”

"What else is so powerful that it can't be used in interstellar battles? Is there any Star Colosseum? Feeling a little baffled, he skipped the page again.

But I made a note in my heart that these strange creatures are so valuable, and I will have to pay attention to them in the future.

Selling special creatures is much more cost-effective than stupidly collecting resources.

"I don't know how much our Gaia Creature Ling can sell?" Yu Yifeng thought to himself. However, he quickly smiled self-deprecatingly, and it was of course impossible to sell Ling.

Then there are all kinds of technology, and this is the big one. All kinds of patent-like pictures are displayed on the screen in rows, and there are only some specific introductions written on them, and there are as many as tens of thousands.

"There's a lot of technology! It seems that technology is the main part of the deal. ”

These technologies are all exchanged by "amoeba points", which are cheap, only a few points, and expensive ones cost thousands of points!

Yu Yifeng thought about it, this kind of point system is actually a kind of behavior that binds users, but it also simplifies the operation to a certain extent.

If the Amoeba Alliance has many markets in the galaxy and is strong, then "amoeba points" are common in all markets. Then the points of this business alliance will become the general equivalent of transactions between star civilizations, which is equivalent to a universal currency like the "dollar" on the earth, and the benefits are of course needless to say.

A group of scientists who have been hungry for a long time can't wait to study this scientific table.

Gradually, it was discovered that the theoretical part was generally expensive, because theory was common to all civilizations.

The table lists the basic theories of mathematics, physics, and chemistry, plus the theories of the interstellar civilization level. Because of the importance and difficulty, each has its own price.

However, the other side does not have a solution to the big problem of the "Riemann conjecture", which makes people quite proud. I don't know, it's because the other party doesn't want to sell, but because they haven't solved it.
