Soon Zhu Lei found a lot of good things, and the price of these things is not very high, some can even be said to be the price of cabbage, but these things are only useful for the cultivation of civilization, and are basically useless for other civilizations, of course, there are some things that can only be used by scientific and technological civilization, but the price of these things is basically very expensive, such as pulsar fragments, planetary cores, etc., and even the corpses of cosmic monsters.

Of course, there are even rare materials that can only be used by high-level civilizations and top-level civilizations, and civilizations below high-level are useless at all, so the price of these materials is very low.

Therefore, he marked the cultivation materials he had discovered, as well as the materials that could only be used by various advanced civilizations, and asked the Yongan Group to purchase them.

In addition to these, Vena's list also includes slaves from other civilizations in the universe, all of whom are captives of civilizations that he has defeated from some primordial planets or in cosmic wars, and these captives are in different forms, and some are even very similar to humans.

It's just that although the Ming Empire still has a very large demand for population, it has no interest in these slaves at all, because if it is really needed, the population of the Ming Empire can even be doubled in five years, after all, the life expectancy of the Ming Empire is now very long, and the mortality rate of the population is very low in recent years, and even the mortality rate has been reduced to double digits in the first two years. Then it won't take a few years to directly fill up the galaxy currently owned by the Ming Empire.

And the Ming Empire now doesn't know how to deal with the Sirius captives in its own hands, after all, the lowest class of the Ming Empire is the sinners, and they also have certain human rights in the laws of the Ming Empire, so there is no need for slaves for the Ming Empire.

He thought for a while and said to the adjutant behind him: "How many Sirius prisoners do we have, just keep it in our hands, it's useless for our Ming Empire, I think it's better to sell it directly to Vina, anyway, our Ming Empire is not afraid that they will rise again to take revenge on the Ming Empire." ”

"Lord Wang, at present, there are nearly 10 million Sirius civilization captives in the hands of our Ming Empire, and these captives are basically old, weak, women and children, and those strong Sirius people basically died in their home galaxy in the war." The adjutant, who had been standing behind him, replied.

"Okay, I see, you can talk to the upper echelons of the empire later, and sell them directly to this interstellar merchant, it will be a trouble to keep them in your hands."

After finishing speaking, he carefully looked at the list in his hand, after all, it was impossible for him to read so many goods in a while and a half, so the Ming Empire must set up experts in all aspects, especially those materials and Pan monks to conduct detailed research on this list, and it will take at least half a year in this world.

At the same time, the Ming Empire determined that this interstellar merchant was a real interstellar merchant and not a space pirate and other civilization exploration spacecraft with malicious intentions, so the Ming Empire also began to organize preparations to trade with him, and the officials of the Ming Empire also notified some of the big merchants and nobles in the Ming Empire, and if the ordinary people of the Ming Empire want to trade with foreign civilizations, the interstellar merchant who is coming now does not have this qualification.

Therefore, if civilians want to trade with him, they can only trade through the great nobles or big merchants of the Ming Empire.

First of all, the government of the Ming Empire also sent a list to Vina, which included the industrial products of the Ming Empire, silk, porcelain, paper, weapons, etc., as long as it was not secret, it was all available for sale, and even included the most powerful nuclear bomb of the Ming Empire.

Although cosmic trade sounds very lofty, in fact, the essence is similar to the trade between countries during the Earth period, in which the advanced civilization exports various industrial products in exchange for huge wealth, and the low-level civilization has to sell a large amount of resources or labor cheaply in exchange for the industrial products of the advanced civilization and various technologies that are far outdated in the eyes of the advanced civilization in order to survive in this cruel universe.

Of course, if the earth does not have Zhu Lei and the existence of the mall, then when the scientific and technological level of the earth's civilization reaches a certain level, the promotion method of the civilization will follow the step-by-step method, then the earth civilization will inevitably use this way to enhance its ability to survive in the universe.

The cosmic trade is no longer used in the currency or other precious metals of the Earth period, and most civilizations use energy as natural currency or barter.

The energy used in the Yuzhuo trade includes various energy ores, antimatter energy, and various energy blocks.

In addition to all kinds of natural energy ores, the rest of the various energies are not produced by low-level civilizations, even the reserves of natural energy ores in the entire galaxy are very small, and the mines where these ores are located are in the hands of high-level civilizations, even if compared to the civilization to vent these energy minerals, high-level civilizations will be desperate to snatch them, because this is one of the ways in which high-level civilizations in the universe enslave low-level civilizations.

It is not that other low-level civilizations in the universe are unaware of this situation, but there is no way to escape such a situation, because the most basic law in the universe is that the law of the jungle is the law of the jungle, so all kinds of industrial products and all kinds of arms and materials produced by high-level civilizations are very popular in low-level civilizations.

For example, the Kara civilization, a vassal of the Ming Empire, before becoming a vassal of the Ming Empire, many things must be purchased at a huge price, or the price of the item itself is hundreds of millions of times the value of the item, just like the Kara civilization buys a spaceship from the black bear and you buy an ordinary medium-sized spaceship from the black bear civilization, the price allows the Kara civilization to make thousands of spaceships of the same size, but the technological content of this is very different. Therefore, the Kara civilization had to pinch its nose and buy these spaceships from the black bear civilization to enhance its strength and improve its survivability in the universe.

After reading the list sent by the Ming Empire, Vena felt very excited, because in the list of the Ming Empire, there are many things that cannot be bought in other fifth-level civilizations, especially some weapons of mass destruction, because these weapons are the foundation of the survival of these civilizations, and they are generally not easily sold to the outside world.

In addition, he also found some special things, maybe these things are very worthless in the eyes of the Ming Empire, especially some plants, these plants are of no use to the humans of the Ming Empire, but for some other civilizations in the universe, these things are very precious.

Just like the common dog tail grass on the earth of the Ming Empire, Vena bought a large number of them, because he knew that these plants called dog tail grass by the Ming Empire were a very tall spice in a fifth-level civilization hundreds of light years away from the Ming Empire, and its price was very high, but this plant was very rare in the galaxy, and he was very happy to be able to encounter a large number of this plant here.
