It's just that the number of parts of the battleship or the number of finished spaceships is very small, and it can be seen at a glance that it is a low-end product, and there is no battleship used by frogmen at all.

Ye Fei could already determine that the Eight Achievements of the Frog Clan was the Shang clan that the Atlanteans said, but the play had to continue, he turned over the part of the battleship and continued to look at the goods on this price list.

On this price list, battleships are classified as a branch of technology products, in addition to battleships, there are also a variety of spaceships, special alloys and other miscellaneous products under the catalog of technology products, all of which have detailed introductions.

In addition to physical objects, some products under the science and technology catalog can also sell manufacturing technology, but the price is much higher than that of finished products, and the lowest can reach more than ten times that of finished products, and it is not uncommon to see hundreds of times higher.

The number of products on the price list was too much, Ye Fei was dazzled before he finished reading one percent, he simply let go of his authority and let everyone look through it with him.

Within a few minutes, Xia Zhuoyan suddenly screamed and shouted like a treasure: "Boss, what do you see I found?" "The picture on one side of the big screen changed, and a cylindrical object full of science and technology appeared on the screen, and a line of words was marked on the side of the rotating three-dimensional screen: Split Beam Cannon!

The black bear saw the word "consignment" under these five words at a glance, and couldn't help but grin: "This thing can't be entrusted by the Atlanteans to the merchant clan to sell on behalf of the people, right?" Is it a specialty of the subhumans? Or are they so poor that they have to sell weapons to make money? ”

Scissors pouted: "You don't know this, do you?" Since ancient times, the windfall profits of the arms trade have been much higher than (poison) goods, and the warships of the subhumans are not afraid to break up the beam. I don't have to worry about falling into the hands of the enemy if I sell as much as I want, and I can also sell it out as much as I can! Boss, how about we buy a few decomposing beam cannons and go back? The above should agree. ”

"I want to!" Ye Fei sighed in frustration, "We don't even know what currency the merchant clan uses to trade, what do we buy?" ”

"I know this!" Ruan Peng excitedly raised his arm high, "There is an introduction on the price list, which is mainly barter, and it can also be settled in gold. ”

"Gold?" Several people shouted these two words in unison.

They all believed that the currency of the Shang clan was something unfamiliar to humans. So just think about looking at the products on the price list. I didn't even look at the introduction of currency.

"Impossible, right? Aliens also like gold? The wolf cub glanced at his wife in surprise, and couldn't figure out how the merchant liked those glittering things as much as women, and almost didn't put an equal sign between the two...... In his perception, there are many times when women are more incomprehensible to men than aliens.

Ye Fei smiled dumbly: "It's not strange. Gold is rare in heavy elemental galaxies. There are so few galaxies with heavy elements. There is nothing incomprehensible about using gold as the settlement currency for interstellar trade...... Other large atomic heavy elements and rare precious metals may also serve as currency. ”

"Why do you have to be rare and precious metals? What is lacking in ordinary galaxies is not only gold, a heavy metal, in the eyes of the Shang people. Maybe a few clumps of lead are more precious than gold. Xia Zhuoyan guessed irresponsibly.

"Nonsense!" Ye Fei was amused by Xia Zhuoyan's nonsense: "Even the Atlanteans have to trade with the Shang clan, even if the power of the Shang clan is not as strong as the subhumans, it will not be weak, such a powerful interstellar race, it is not difficult to control a few heavy element galaxies at all, how can lead, a heavy metal, be regarded as a treasure by the Shang clan?" ”

"What about silver? Is it useful? Xia Zhuoyan curiously asked a new question.

"This ...... You ask me, I ask who goes? Ye Fei was helplessly defeated in front of the curious baby.

As early as hundreds of years ago, human beings began to study aliens, and after the appearance of aliens, the study of alien behavior, habits and society has become an important social science.

"Silver is certainly worth much worse than gold." Jiang Xue said suddenly.

"Why?" Xia Zhuoyan still bit this question, "Ancient people shouldn't know how these two metals are formed, let alone know that silver has more reserves than gold, right?" Is it just because gold is more beautiful than silver? ”

Jiang Xue explained with a smile: "Silver and gold are both heavy elements formed in supernova explosions, when the mass of a supernova is about eight to nine times that of the sun, the heaviest element formed is silver, and only stars with greater mass can form gold." Therefore, gold is much less abundant than silver in the entire universe, and naturally it is much more valuable. ”

Xia Zhuoyan looked suddenly enlightened: "According to this, let's detonate that blue giant star at most silver?" ”

"Theoretically, that's so." Jiang Xue replied.

Xia Zhuoyan glanced at Ye Fei aggrievedly: "Lead and mercury or something, the atomic weight is larger than gold, isn't it more difficult to synthesize and more valuable?" ”

Ye Fei felt that this question was too acute, and after thinking about it, he said: "I can't talk about this problem, according to what you say, there should be less lead in nature than gold, but in fact there is much less lead than gold...... I think it may be because lead ore is very concentrated and easy to refine, and gold is very scattered and difficult to refine. ”

"There is more lead and less gold on the earth, maybe there is more gold and less lead on the planet next to it!" The black bear guessed with a grin.

"Come on, don't bother with these unanswered questions." Ye Fei continued to look at the price list, "It's fucking weird, think about it, there are seven continents in the world, several races and more than 2,000 ethnic groups, and no one can see anyone in ancient times, so how can they all know that silver and gold are precious metals, and they all know that the value of silver is not as good as gold?" ”

"Chief, why do I feel a chill down my spine when you say that?" Scissors shivered exaggeratedly, "It sounds like someone has taught everyone in the world that gold is more valuable." ”

"That's it." Black Bear also said, "It's okay to say that the Silk Road existed thousands of years ago, and the exchanges between the two sides have never been interrupted, but what about the Americans? They had never traded with any other continent! ”

Jiang Xue opened her mouth to speak, but she hesitated and swallowed back the words that came to her mouth. (To be continued......)
