After thinking for a while, Zhang Yuan frowned and said: "theoretically, a high-dimensional fragment should not be able to replace the core technology of the fourth level civilization I didn't even see the price of curvature technology in the transaction list. This means that the price is at least 50000 points or more! "

The price of a conventional technology with three-level civilization is about two digits. For example, the full set of production methods of an electronic chip only needs 33.2 amoeba points! There are some simple technologies that can be obtained in single digits.

The price of a conventional technology of level 4 civilization ranges from three to four digits.

But when it comes to core technology, its price will rise sharply. In this table, the highest price is a kind of subatomic material theory, the price is 50000!

More than 50000 things have not been written down. Maybe they are Planetary Fortress, curvature technology and so on, which must be beyond human's affordability.

Zhang Yuan sighed and said: "although the high-dimensional debris has a high technological content, it is just like a Book of heaven for the low-level interstellar civilization. Even the fourth level civilization is not enough to solve the mystery."

"This kind of unseen and useless thing, besides being used as a collection, can at most be used as an electromagnetic shell..."

The high-dimensional debris has been studied for such a long time, and no great achievements have been made. Some good guys have specially designed an acceleration weapon for it, just like an electromagnetic gun.

Anyway, no matter what material the other party is, or even a neutron star, as long as it is hit by this thing, it will still be eaten.

Speaking of this, Zhang Yuan said with a smile: "if high-dimensional debris can really be exchanged for curvature navigation technology, it must be exchanged! It is the amoeba civilization that knows that we have virtual space technology. However, the amoeba civilization is a level six civilization. They should not tell all the information they know to their subsidiary civilizations. "

"What's more, this trading market is monitored by amoeba civilization, and there are other six civilizations Huantai civilization is not going to start in its own market. "

"If these conjectures are true, there is not much risk in trading this high-dimensional fragment. Ten birds in the forest is better than one bird in the hand Where is there anything safe in the world? Compared with the benefits, the risk is worth the effort. "

"Curvature technology is our top priority at the moment."

"Yes, that's what I think."

In addition to high-dimensional fragments, another system that human beings can trade is their own unique science, the history of new civilization.

This is an applied mathematics and a management discipline. Human scientists think it is of great value.

Trafficking in this subject, in theory, will not endanger the safety of mankind itself. Just like "capital" and "wealth of nations", what about letting others know?

Each civilization is different in ideology and has its own unique history. Therefore, according to the history of new civilization, it will also follow its own unique path and will not repeat with mankind or interfere in human internal affairs.

Of course, the so-called "high value" is also imagined by human beings themselves. If the other party's bid is low, it will not be sold at all.

The last thing to win is virtual world technology, which is the core technology of human beings. Although it has high value, it will not be sold.

There is not even a word mentioned in the transaction information

That's all human property.

In such a discussion, the speed of the spacecraft is gradually speeding up, and it is estimated that it will take one month to reach the central trading place.

As time goes by, some strange plasma clouds appear outside the window, just like large clouds floating in the universe. Human transport ships almost navigate in the gaps between the clouds.

Zhang Yuan frowned, thinking that these plasma clouds might be some defensive war weapons.

The various observation devices of the spacecraft have no way to penetrate the thick plasma cloud, and they don't know what is in the middle of the cloud.

One of the weapons experts said: "there are a small amount of helium and hydrogen ions in these plasma clouds, which are corrosive to a certain extent. If a spaceship flies around in it, it will soon be scrapped. Therefore, it should be a defensive means in positional warfare. "

As the strongest acid in the universe, helium hydrogen ion can react with almost any substance, including various carbon nanomaterials and composite ceramics. The Huantai civilization has also warned human spaceships not to fly in the clouds, otherwise they will only be responsible for the accidents.

“…… At the same time, it can prevent laser, interfere with electromagnetic wave communication, and stop foreign spacecraft flying everywhere. A market must be orderly. "

"But how did such a large plasma cloud come into being? I guess there must be a space fortress in the middle, using the super magnetic field to control these clouds. "

"Maybe there are mines and other weapons in it?"

It took nearly 10 days to pass through these fuzzy clouds.Finally, the clouds in front of us dissipated, and everything in the inner layer of the whole planetary system suddenly became bright again, including more than 20 star fortresses and two wooden planets that can supplement energy.

Human transport aircraft have received all kinds of electromagnetic information.

Zhang Yuan's mood was slightly excited, and the dreariness of crossing in the clouds a few days ago was swept away.

But

The Battle Fortress of planet class is really big!

This large transport ship is huge, but compared with the planet, it is really an ant at the foot of an elephant. No, it's like a gravel in the mountain

All kinds of huge buildings, as huge as the sky, are displayed in people's eyes. There is a big round guy. I don't know whether it's a gun barrel or something else. The black hole can even fill the next "Kunlun Mountain"!

"It should be a planetary engine. It's too violent! "

Planetary Fortress, an interstellar civilization that has lived in the galaxy for more than 100000 years, usually chooses to develop such super spaceships. For example, there is a Planetary Fortress in the parent planet of badit civilization captured by human beings.

First of all, we need to empty most of the planet's interior, and then install a huge engine. At the same time, we need to ensure that the planet's interior is strong enough. When it sails, it will consume tens of millions of tons of nuclear fuel in one second, which is the highest aesthetics of violence below the fourth level civilization.

In a planet 1 million kilometers away, countless spaceships and robots are coming and going on the planet, so that there is a huge ditch on the surface of the planet.

This should be a planet that has not yet been fully developed. Now, as the whole trading market will leave in 3000 years, if it is still not completed, it may be disposed of at a low price.

Zhang Yuan and others just looked at it eagerly. It is impossible for human beings to buy anything. It is the dream of all mankind to have a Planetary Fortress But think about it carefully. Without curvature navigation technology, this thing's mobility is really not good.

"Without curvature navigation, Planetary Fortress can only navigate near the cosmic string. Once out of the cosmic string, lose gravitational acceleration, rely on their own planetary engine, mobility is too poor, and it will cost a lot of fuel to be able to promote themselves
