Deep Space Fleet

On the fourth day, Gliese Civilization held another mathematics conference. Because Zhang Yuan himself is a mathematics expert and has not slackened in his studies over the years, he is obliged to participate in this conference on behalf of mankind.

All the narrations are very profound. What shocked Zhang Yuan was that the mathematics of this civilization is indeed very powerful without commenting on other subjects for the time being!

Even, it may be better than human mathematics!

In human society, there are many directions of mathematics, and even the foundation has not been laid, but it has been perfectly confirmed by the Gliese civilization!

"About your idea, I have another question. By the way, in our language, it's called Hodge's conjecture..."

"Our best idea at the moment is this..."

After three hours of discussion, Zhang Yuan became more and more excited, his old face flushed.

As if a raging flame was burning in the chest, this kind of communication really has a hearty sense of joy!

Of course, human mathematics did not embarrass Zhang Yuan. Regarding the "mathematical unification" plan and some grand programs, including a small part of the history of new civilizations, plus the article from Zero-XZ The extraterrestrial papers that were cheated out of the Internet also made the other party's mathematicians scream and be amazed.

There is a big surprise in the direction of thinking of the two parties. In mathematics alone, there are many things that can make up for each other.

After the meeting ended, Zhang Yuan deeply understood the benefits of mutual communication between different races.

There are some whimsical ideas, if you follow the thinking of human beings, you may never think of them.

He thought secretly in his heart: "If a civilization is broad-minded enough, a multi-civilization alliance must be stronger than a single civilization..."

"...Mr. Ambow, the mathematics you gave are indeed very remarkable results. But I noticed that they are all old things from 40,000 to 50,000 years ago... Can you tell me about your latest mathematical progress? "

When walking out of this conference room, Zhang Yuan asked casually.

Mathematics is such a thing as black and white, right is right or wrong is wrong, and when you meet someone you can communicate with, you can really get closer quickly, and even race is not very important.

Anyway, these things can be said to be high-spirited, and it is too difficult to convert them into productivity.

This Gliese professor named "Ambow" has fallen into a state of almost fanaticism in this mathematics meeting. Even though the meeting is over, he still has something to say, and he keeps asking questions after Zhang Yuan.

However, upon hearing Zhang Yuan's inquiries, its enthusiasm seemed to be suddenly quenched by a basin of cold water.

"Oh, it's not that I don't want to say..." the university scholar Anbo sighed, "It's really...not worth mentioning! Not worth mentioning!"

It left very frustrated, and before leaving, it seemed that its entire back was bent.

Back in the residential area, Zhang Yuan asked a few more friends, and suddenly found that the content of the exchange in the past few days was almost all the excellent culture before the appearance of the second alien civilization.

There is not an iota of history since the second alien civilization.

Zhang Yuan had some guesses in his heart, "That is to say, after the second interstellar civilization appeared, did problems occur quickly..."

This thing is weird, really weird...

"Even, the second interstellar civilization may not necessarily be kind..."

"But why help them develop into the electric age?"

Finally, after a week, all the art and science exchanges were over, and all the high-level leaders came to the table to start the final cooperation negotiations.

There is nothing to write about, Zhang Yuan straight to the point: "...Dear Your Excellency Gan Yaduo, after such a long exchange, we can indeed understand and appreciate each other."

"Cooperation is of course the best choice for both of you and me. We don't have a deep hatred, and there is no need to fight for a planet."

"The starry sky is so vast, our human vision is never limited to one planet."

Zhang Yuan tentatively said: "But I would like to know, what exactly is the cooperation you want? Is it the trade between the two sides, or the exchange of science and technology? Or the development of culture..."

The leader of the Gliese civilization hesitated to speak, and then several people looked at each other, as if they had made up their minds.

Gan Yaduo suddenly said: "We... want a spaceship!"

"Spaceships capable of traveling between the stars, for which we will pay almost anything!"

"Including the knowledge you want, as well as a large number of production tools, can be used as trading targets."

Zhang Yuan's pupils contracted slightly, and he was taken aback. All of a sudden, cold sweat broke out from his back!

At first, he thought that the other party wanted the "Earth Times" of human beings, but of course it was impossible. After two seconds of silence, he realized that the other party was not referring to that.

"Impossible!" After rejecting the other party, he added: "...At least for now, it is impossible."

"Our human civilization is indeed capable of producing stellar spacecraft, and in the long history, it has produced more than one. But that is our powerful mother civilization, not our current child civilization."

"The current productivity is still far from being able to produce stellar spaceships. We need at least one or two hundred years of development... So your request, I am sorry that I cannot accept it for the time being."

These are big truths, big truths that a fool can analyze. If human beings can produce stellar-level spaceships, they will directly crush the Gliese civilization, and even negotiate a fart.

Moreover, the cost of building a star-class spacecraft is too high, and each one has to occupy a huge amount of productivity of the new civilization.

Even if there is such a construction plan in the future planning, these spaceships are used to realize the "seeding plan" and "wandering plan".

"If you sell a spaceship to the Gliese..."

Zhang Yuan was frowning, thinking about the gains and losses. If he had to spend tens or hundreds of years of development of the entire civilization just to gain some knowledge, then he had to consider whether it was worthwhile.

"If the benefits are big enough, it's not impossible... But if it's just mathematical knowledge... No." He shook his head lightly, even though he is a mathematician, he is so curious about the solutions to some mathematical problems . It is impossible for him to sell the interests of the entire human civilization out of curiosity.

The other party asked again: "Then what price do you think we need to pay in exchange for a spaceship?"

After a while, Zhang Yuan said again: "Your Excellency Gan Yaduo, I think you may have underestimated the difficulty of building a stellar spaceship. How big a spaceship do you need? How many people can it carry and how far can it travel? Complexity... How many production tools do you need to carry inside? These are all things that need to be considered."

"The more difficult the spaceship, the higher the cost of course... This price... is actually difficult to estimate."

Gan Yaduo said directly: "We have been thinking about this issue for a long time. The price is not a problem, as long as your civilization can be built...we will definitely be able to afford this price!"

As a result, it actually came up with a very detailed plan, including the parameters of the spaceship ecosystem, the population it can carry, etc. It was obviously a long-term plan, not a temporary idea!

So much so that the entire negotiating team was a little puzzled by Monk Zhang Er, and they looked at each other in blank amazement.

"Wang Junpeng, what's the situation? Even I can't make a decision on this transaction request... The Earth Times spent tens of millions of engineers' productivity, and the entire 30-year construction, do you know? We now have 500,000 people ..." Zhang Yuan asked softly in the earphone.

Wang Junpeng was also dumbfounded. As the first batch of diplomats who came here, he was also stunned at the moment, "I really... don't know what they really think!"

Could it be that this group of Gliese people also want to imitate humans and colonize deep space? This is too incredible!

"They don't want this planet anymore?"

"..."

Zhang Yuan cleared his throat and returned to normal. He thought carefully about the plan given by the other party, his brows furrowed and then relaxed.

The reward given by the other party is indeed extremely generous. Not only will they give humans precious knowledge, including mathematics and cosmology, but they will also give away some precious heritage left by alien civilizations!

Including a... so-called "Full Auto Universal Factory"!
