There are many items in this list, the first of which is various cultural classics.

The history of this civilization is so long that it has changed dynasties I don't know how many times. Whether it is an official collection of classics or folk classics, all human beings will receive them correctly.

Anyway, you don't need the original, just scan it electronically and upload it. It is also quite interesting to put these cultural classics into the virtual space and restore the entire Riley culture as it is.

The second need is the different biological specimens on the planet, and if there is the help of the indigenous people, there is no doubt that the progress will be faster.

After all, there are only more than 1,000 members of the scientific expedition team who have landed on this planet, and it is still a little insufficient to investigate an entire planet.

Humans also want to buy some living World Trees, as well as native animals and plants.

According to this list of transactions, a little metal can be exchanged for a whole bunch, which is much more effective than robbery anyway.

As for the third, only a few diplomats know about it, that is......

Population!

Humans need to grab a little Riley and enter the virtual world of 14 to help explore the construction of the virtual world. It is also necessary to understand why Riley people are intelligent and how their brain structure differs from that of humans......

This transaction project is not a problem at all for the aristocracy of Riley.

They themselves retained slavery.

Trading in slaves is not a so-called conscience condemnation at all. As for why the Spirit Messengers needed some slaves, it was not something they could handle.

And what human beings pay is some metal devices, including some steel smelting devices, iron-making furnaces, blowers, and other very cheap things, and if the other party wants, they can also share a small amount of knowledge.

From a certain point of view, human beings seem to have suffered a small loss, but these small losses do not matter to people. Since I came here, it can be regarded as a kind of fate, and it is a good thing to be able to make the other party improve a little.

At least all the people of Kunlun Mountain will feel happy in their hearts and will have a sense of moral pride, which is already the greatest benefit.

Seeing this list, all the Riley people breathed heavily, and they were in a state of increasing fanaticism.

"This ...... This ......"

A hundred different books can be exchanged for a metal knife!

"O god of money and wealth! Do you really pamper me? "In contrast to such great wealth, the king felt that he was a complete pauper, and that he had been viciously struck in the head by a pie that fell from the sky!

And it's the kind that smashes right in your mouth, so you can eat it without even stretching your hands.

It's the real ...... Happiness?

The Rileys had mastered the rudimentary math before they could have built a huge nation, and the king was calculating the benefits he could gain at a rapid pace.

"Cultural Classics...... By the way, the speed must be fast, there are some books that are treasured by many people, and after trading once, humans don't want to do it a second time. Thinking of this, the king quietly instructed his men to prepare the relevant content, and they must be ahead of the others.

And the dignitaries and nobles sitting below also thought of this, and were a little reluctant, all the benefits were taken by the king, what is this?

But because humans are still present, it is impossible to attack immediately.

The king was shocked when he saw that even his henchmen were pale...... Also, the benefits here are too great, which is equivalent to a direct doubling of wealth several times!

Who doesn't care?!

At least give some benefits to your own henchmen......

After pondering it like this, the king was still in a state of confusion...... But no matter what, I definitely won't lose it.

The nobles and nobles are all holding back their greed, thinking about how big of a piece of the pie they can get......

If the king is too greedy, then ......

By the way, maybe it's a test of desire from the gods?

It was only for a few seconds, and all the Riley people had their own ghosts, and there was no even a voice for discussion.

Wang Junpeng touched his nose and guessed the thoughts of this group of Riley people in his heart.

Some of the human diplomats in the back looked at each other, and they didn't know what to say, but because they were hindered by their cultivation, they all just stared blankly.

Backward civilizations are like frogs at the bottom of a well, where they can only see a little bit of the sky.

"Well, some metal just makes them crazy with excitement, maybe they are still thinking about some kind of conspiracy for these things, what a ridiculous thing." Wang Junpeng lamented in his heart.

But who is the human race to laugh at them? Isn't it the same expression when human beings acquire advanced civilization technology?

After all, it's just 50 steps and 100 steps of laughter.

"If we encounter an advanced civilization that is willing to give us curvature technology, our emotions will be the same, right?" Someone suddenly said in the headphones.

"yes, alas...... Current research progress has been slow. Curvature technology is still just a fantasy. ”

"No, it's not fifty steps and a hundred steps." Wang Junpeng whispered in his headphones: "They are greedy for wealth, and they want to have greater wealth from the individual level, but we are eager for the unknown, and we want to explore more things from the group level, which are two different mentalities...... The human beings in the Kunlun Mountain fleet still have the determination to move forward and have strong scientific thinking, rather than being restricted by rules and regulations, which should be the biggest difference. ”

And in the trading materials provided by human beings this time, in addition to these metal tools, there is also a lot of knowledge.

This knowledge includes elementary mathematics, elementary chemistry, physics, and astronomy, and the price is not too high.

Don't be chemistry, which can make the burning phenomenon of this civilization more common and make the cost of flame lower.

Of course, all knowledge is hidden, and it is impossible for human beings to prepare some reference materials for them, but they just flipped through it according to the human junior high school textbook, and the whole content is simply obscure and requires a lot of effort to study.

In the short term, it will not yield much benefit, but in the long term, this knowledge is the basis for the progress of a civilization.

"It's up to them...... But will they choose, will they delve into it? It's hard, it's hard. Another diplomat sighed.

From the perspective of current observations, it is unlikely that this civilization will save itself.

In this civilization, the flame has been endowed with the sacredness of religion, a great power bestowed by the gods. Each time a flame is lit, it needs to go through a large-scale sacrifice, from which a small amount of metal is smelted.

What would happen if flames were spread on a large scale?

What can be popularized naturally loses its sacredness, and this kind of subversive knowledge is inevitably not allowed by religion.

Wang Junpeng shook his head, "If they don't save themselves, what do they care about us?" There are no 100,000 similar civilizations in the universe, but 10,000, where can we save them? Just give them a chance, if they can't seize the opportunity, we don't need to do more, do you want to force them to study physical chemistry, and then set off a revolution in thought, do you think it is necessary for us to train the indigenous people here? ”
