Zhang Yuan is actually quite good at politics, but these diplomats are capable enough, and he doesn't point fingers too much except for the occasional advice.

The politics of this trading market are simpler than some virtual worlds. After all, each interstellar civilization is independent, except for science and technology trade, mutual cultural exchanges and commercial trade are almost zero, if they don't like each other, then no communication is.

Like in some virtual worlds, trade and exchanges between countries are integrated and inseparable, and that kind of political struggle is called really complicated, and people spend most of their energy and wisdom on infighting......

In this way, a month passed again, and after the establishment of an embassy on a planet with suitable gravity, and communication with the rear fleet, the first scientists had begun to try to participate in various exchange meetings.

The exchange between civilizations and civilizations is like this, where is the friendship that is really difficult to break, it is okay to huddle together for warmth, but when it comes to interests, they will immediately quarrel, but in the next second, they have to be cheeky and huddle together again to keep warm.

……

In addition to these diplomatic affairs, people also received some information about the sixth-level civilization that remained in the trading market, the Hicks civilization. The application for trade with the Hicks civilization has been handed in and is still in the queue.

Before it's humans' turn, it's always good to find out a little bit more.

The Gaia faction, a rather mysterious faction in the universe, has no idea what these ancient civilizations are studying because the minimum entry threshold is a sixth-level civilization. Their behavior and philosophy are unknown, and from the outward appearance, they have a certain degree of goodwill towards the weaker civilization.

As a member of the Gaia faction, the Hicks civilization communicates with the trading market through faster-than-light communication.

"This civilization likes to buy up the history, culture, and art of different civilizations, and it pays a lot of money for it. In fact, it doesn't matter if you don't have art, as long as you sell your history, you will get a lot of amoeba points...... The more twists and turns in the whole historical process, the better, and the more storytelling the better. ”

"What is this? For the new interstellar civilization, is there a newbie reward? That's a lot of income. ”

As he walked, Zhang Yuan said with a little puzzlement: "Moreover, how can they distinguish the authenticity of the artwork?" ”

Zhao Qingfeng replied: "I don't know, it's weird to think about." However, most of the interstellar civilizations here have sold their own history and culture......"

The scientists had landed on a planetary fortress with the right gravity, and had been living here for nearly a month, spending most of their time investigating part of the planetary fortress's structure.

A planetary fortress is so big that less than a thousandth of a place can be surveyed in a month.

This expedition, of course, also costs money, not too expensive, 5 amoeba points, for poor human beings, is a lot of expenses.

Zhang Yuan shook his head and couldn't help complaining: "This Huantai civilization is really the true inheritance of capitalism, and you have to pay for a slightly better service...... I estimate that this planetary fortress is the one that is relatively old, and the internal mechanical structure of the star can be used for reference, but the weapon structure above is already very outdated. It is possible that the Huantai civilization was built when it was a third-level civilization, and it is difficult to completely improve it. ”

"This planet, there is a possibility that it will be disposed of at auction. The entire market is about to be relocated, and those that should be eliminated must also be eliminated directly. ”

Everyone discussed this and smiled bitterly, it is impossible for human beings to afford such a space fortress...... This is an opportunity that can only be missed.

The mountains and seas on the surface of this planet have long since disappeared, and there are endless plains as far as the eye can see. Not far away, about 100,000 meters, there is a huge war fortress, 300 meters high and the size of a small hill, which is capable of accelerating the speed of an electromagnetic cannon the size of a projectile to sub-light speed.

Further afield, there is an obelisk-like device, with a total height of 30 kilometers, which is supposed to be the so-called curvature generator.

100 kilometers below the surface of the planet, there is an artificially constructed sea, which is stocked with a large amount of water, metals and various mechanical devices. There is also an atmospheric environment that can accommodate life, and the living place in it is leased by a race called "Assman".

In short, all of it, if you have to use human words: enormous. The inner space of this planetary fortress was dug up by 7 different civilizations over a period of 3,000 years. The entire planet was hollowed out in half, and after the development of this planet, several civilizations accumulated a lot of experience and chose to return to their home galaxy to develop their own planetary fortresses.

This is also the benefit of cooperation between civilizations, even if they help others to work, it is not in vain.

It is said that this is just a medium-sized, old space fortress, and when standing here, facing the endless emptiness, people still feel a faint sense of oppression, as if facing the oppression of the universe.

This is not humanity's own battle star after all.

The car drove forward at high speed, and Zhang Yuan controlled the electronic instrument in his hand and recorded everything he saw...... These are all allowed in the transaction.

At this point in the discussion, many scientists began to lament the poverty of their families, backward but not backward, in the third-level civilization is considered to be above average, especially after the invention of the auxiliary brain, human beings can be regarded as a smart species. But it is indeed poor! The background is too poor!

"By the way, are we really going to sell our history? It feels weird...... Will it cause security issues? Zhao Qingfeng touched his chin and said with a little doubt: "We don't know, why does the Hicks civilization collect the history of various civilizations, do they also have a new civilization historiography?" How about we just sell this subject to them? ”

Zhang Yuan smiled bitterly: "I don't know if we should sell our history, or sell part of it...... What does the Council of Science think? ”

"It's still being discussed, and the argument is very intense...... Anyway, in the end, you will definitely be able to decide the winner and loser, what is your opinion? ”

"In the face of the unknown, you still have to maintain enough awe."

"You mean, don't sell?"

"No, if you sell it, you have to sell it thoroughly. Actually, we've already made a deal with the Gaia faction...... That is, the artificial intelligence Ita in that high-dimensional prison. Zhang Yuan smiled and said, "If we sell these cultural histories, will we lose what we already have?" No, at most, let the higher-level civilizations know that in the Milky Way, in the solar system, a human civilization was born, and the development is not bad. ”

"If the other party has good intentions, it's actually nothing, and by the way, you can also climb the friendship; If the other party has malicious intentions, can we protect ourselves well if we don't trade? ”

"Weak...... It's a cruel thing. Foreign Minister Chen Mu's expression remained unchanged and he said these words calmly.

Whether it's a dead face, a begging, or anything else, there are not many choices that humans can choose.
