"Every civilization is careful to maintain its purity and independence, even the greatest civilization."

This is what Wang Qian has been told the most recently.

The trade with the interstellar merchants had passed, but Wang Qian didn't know anything.

For example, he doesn't know what the Star Trader looks like, what kind of transportation the Star Merchant takes, or what he does with Byth.

At present, the only thing Wang Gan knows is the logo of the Merchant Alliance, and that logo alone makes Wang Gan gain a lot of knowledge.

The logo appears prominently on the Star Traders. At first, Wang Qian was still thinking about how to identify and how to consider the individual differences between interstellar merchants.

Who knew that Wang Qian was told that the conspicuous position of this logo was relative to the person looking at the interstellar merchant.

In other words, as long as there is a living organism with a perception system, it can be a very eye-catching mark in its own perception system.

The mark cannot be removed. Similarly, as long as the merchant being marked exists in any form, the mark cannot be removed.

Wang Qian once thought that if an interstellar merchant was bombed into scum, then how would this logo exist, but unfortunately, to no avail.

'The logo is universally constituted' Similarly, people who see the logo will automatically know what the logo means.

To be honest, Wang Qian didn't believe in this kind of thing at first. This is because the cognitive structure of each intelligent life is different.

It's hard to imagine any structure that all intelligent life in the universe can identify.

"What if there is no concept of merchant in a civilization?" Wang Qian asked with some curiosity.

"Then this civilization has this concept the moment it sees this sign." Lele replied helplessly.

"It's amazing. When will we have this kind of technology? I think it's a lot like our mind-to-mind technology. ”

"Other people's homes still use solar energy, can the utilization rate be the same?" Wang Gan's words were scolded and he would go.

"It's really hard about the technology, it's the adaptability and the priorities behind it.

We don't even know why we see that logo in what we think is prominent.

And according to speculation, this should be the next level of technology at the level of the Star Path Pioneer civilization. Lele said.

"To maintain the purity of civilization?"

"It should be."

"It's really funny, even advanced civilizations that we can't even imagine are afraid of this." Wang Qian was a little surprised.

"It's not that I'm afraid, it's just that the cost isn't cost-effective. Based on the available information, we believe that there is a medium that is common to both advanced and low civilizations, and that it conforms to the principles of physical sociology, and that high concentrations are transmitted to low concentrations at a certain scale. Lele said.

"Is this medium the spirit mentioned at the last Weapons Development Report?" Wang Qian asked.

"Probably, we don't have any further information yet, so it's useless to guess." Lele crawled on the table, lazily playing with the Fortune Cup reward dice.

After waiting for another three or four months, the news about the last trade was announced.

"The content of trade consists of a number of rare substances, which are exchanged with each other. The species is unknown, the quantity is unknown.

It includes a mechanical structure optimization technology, an energy optimization technology, and a set of basic science and technology systems, including the main scientific and technological branches of level 1-3 civilizations.

It is still a technology exchange, and the outflow technology is artificial intelligence technology during the Second Empire (excluding the artificial intelligence stage breeding clues). The idea of the construction of virtual space in the early days of the Second Republic (without specific ideas). and the Early Fourth Republic's mass bomb technology.

Including a number of cultural achievements for research, the specific content is unknown, the number is unknown, and the time of lifting the ban is unknown. ”

Looking at the one-page list of transactions, Wang Qian carefully searched for the details.

"No, that's all the information that's been released so far." Lele still said lazily.

"That's it? It's all about writing technology that is already outdated. Wang Qian asked.

"Obsolete technology is low-risk, low-cost, and can be traded multiple times, which is very helpful in analyzing the composition of other civilized societies." Lele explained.

"You have a point in saying that, but do we trade many times during a Star Path journey?"

"It should be, interstellar merchants are very common in the star path, and it is not unusual for them to come to the door.

If possible, Beit would like to try to communicate with his fellow civilizations. Lele said.

"Equal civilization, aren't you afraid of affecting the independence of civilization?" Wang Qian was a little curious.

"You can't turn a deaf ear and pretend not to see it for the sake of independence, saying that Beit is already the pinnacle of the fourth-level civilization.

It is possible to reach the height of a fifth-level civilization at any time due to technological breakthroughs.

If you don't dare to communicate with the civilization of the same level to this extent, then you might as well go to your own house. Lele said.

"Look at what you said. I've noticed that you've been a little listless lately, what's going on. Wang Qian hugged Lele.

“…… I've been studying lazy ...... lately" seems to be to prove this, and Lele slowed down for a while before he spoke weakly.

"I seriously suspect you're spending all your energy in the virtual space. I've heard Reagan say that you play in the dice of fate. ”

"Hmph~"

"Is that playing, that's contemplating fate?" Lele looked at Wang Qian with a little contempt.

“……”

"I can't mess with it, I can't afford to mess with it." Wang Qian retreated in defeat and took Lele to class.

The course "Overview of Civilization Exchanges" is very popular now, but it is only scratching the surface, and if you want to really see some dry goods, you have to check the information yourself.

"Civilizational exchanges will inevitably leave behind exchanges, and there are differences between civilizations on both sides of exchanges, and whoever can absorb them into their own development system will become the victors of civilizational exchanges."

The examples given in the class are still old examples of the war with the Yuzheng civilization during the Third Republic.

You must know that it was an example more than 400,000 years ago, and at that time, Beit was sitting on the Heavenly Star, and Yuzheng Civilization was not an opponent at all, and the scene was almost one-sided.

Beit has absorbed a lot of Yuzheng's technology, and the compatibility is good, only Yuzheng's unique intelligent animals have not made any progress so far.

"Wait a minute, are you going to attend a seminar related to the exchange of civilizations, there will be top-secret information announced at the meeting." Li Baoshen mysteriously sent an invitation like Wang Qian.

"I think you have to pay attention to your demeanor first...... It's a little ...... when you look at it like this."

"It's a bit obscene, isn't it," Li Bao straightened up his clothes and makeup, and got serious.

"Student Wang Qian, if I want to invite you to a discussion meeting that is absolutely informative, you will feel that this trip is worthwhile."

I don't know why, Wang Qian still feels that his content has an obscene flavor.

In the end, Wang Qian decided to take a look.

"What? You said that Beit also received a letter while trading with the interstellar merchants? Wang Qian was a little surprised.

"yes."

"This kind of gossip also makes the spread? Bate doesn't care? ”

"This look is intentional, don't you see that your family is happy and didn't remind you.

You will receive a warning letter and ask to go to the Ministry of Education. But it doesn't matter, who hasn't had a few warning letters, who hasn't been young. Li Bao patted Wang Gan's shoulder.

Knowing why, looking at Li Bao's slightly chubby body, Wang Qian felt a little obscene again......
