On the fourth day, Glitze Civilization held another mathematics conference. Because Zhang Yuan himself was a math expert and had not slacked off in his studies over the years, he had no choice but to represent human beings to attend the conference.

All the narratives are very profound. What shocked Zhang Yuan was that other subjects would not be commented on for the time being. This civilized mathematics is indeed very powerful!

Even, it may be better than human mathematics!

In human society, there are many mathematical directions, and even the foundation has not been laid well, but it has been perfectly verified by the Glitzer civilization!

"I still have a question about your idea. By the way, in our language, it is called the Hodge conjecture..."

"This is our best idea right now..."

After 3 hours of discussion, Zhang Yuan became more and more excited, and his old face turned red.

It was like a blazing flame burning in the chest, and this communication really felt a refreshing and refreshing feeling!

Of course, human mathematics did not embarrass Zhang Yuan. The plan for "Mathematics Unification" and some grand programs, including a small part of the history of new civilizations, plus the alien paper tricked from zero-xz, also made the other mathematicians scream and were amazed.

The thinking direction of both parties was very surprised. There were many things that could be made up for each other in mathematics alone.

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

There are some wonderful ideas that may never be imagined if you follow the human mind.

He thought secretly in his heart: "If a civilization has a broad mind and a multi-civilized alliance, it will inevitably be stronger than a single civilization..."

"...Mr. Anbo, the mathematics you gave is indeed a very amazing result. But I noticed that they are all old things from 40,000 to 50,000 years ago... Can you reveal your latest mathematical progress?"

Zhang Yuan asked casually as he walked out of this conference room.

Mathematics is a thing that is clear in black and white, right is right and wrong, and when encountering an object that can be communicated, it can indeed quickly get closer, and even race is not very important.

Anyway, these things can be said to be very high and slim, so it is too difficult to convert them into productivity.

The Glitzer professor named "Anbo" was already in an almost fanatical state during this math meeting. Even though the meeting was over, he was still a little unsatisfied and followed Zhang Yuan and asked questions constantly.

However, when he heard Zhang Yuan’s inquiry, his fanaticism seemed to be suddenly extinguished by a basin of cold water.

"Oh, it's not that I don't want to say..." An Bo, a great scholar, sighed, "It's really... not worth mentioning! Not worth mentioning!"

It left in great depression, and before leaving, it seemed as if its entire back was hunched over.

When he returned to the residential area and asked several friends, Zhang Yuan suddenly realized that the content of the exchanges in the past few days was almost all the excellent culture before the emergence of the second alien civilization.

The history since the second alien civilization is not at all.

Zhang Yuan had some vague guesses in his heart, "In other words, after the second interstellar civilization appeared, did the problem quickly appear..."

This is a strange thing, really strange...

"Even, the second interstellar civilization may not necessarily be rewarded with kindness..."

"But why help them develop into the power era?"

Finally, a week later, all the art and science exchange meetings ended, and all the senior leaders walked to the table and started the final cooperation negotiations.

There is nothing good about it, Zhang Yuan said straight to the point: "...Dear Mr. Gan Yaduo, after so long exchanges, we can indeed understand and appreciate each other."

"Cooperation is of course the best choice for you and me. We do not have a deep hatred, nor do we need to fight for a planet."

"The starry sky is so vast that our human eyes will never be limited to one planet."

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

The leader of the Glitzer civilization wanted to speak but stopped. Then several people looked at each other for a moment, as if they had made up their minds.

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

"We can pay almost any price for spacecraft that can sail between stars!"

"Including the knowledge you want and a large number of production tools, they can all be used as transaction subjects."

Zhang Yuan's pupils contracted slightly, and he was shocked. Suddenly, cold sweat emerged from his back!

At first he thought that the other party wanted the "Earth Age" for humans, of course it was impossible. After two seconds of silence, he realized that the other party was not referring to.

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

"Our human civilization is indeed able to produce stellar spacecraft, and over the long history, it has produced more than one. But that is our powerful mother civilization, not our current sub-civilization."

"The current productivity is far from being able to produce star-level spacecraft. We need at least one or two hundred years of development... So I am sorry that I cannot accept your request for the time being."

These are all big truths that fools can analyze. If humans can produce star-level spacecraft, they will directly crush the Glitzer civilization and will be a big deal.

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 are indeed such construction plans in future planning, these spacecraft are used to implement the "sowing plan" and the "wandering plan".

"If you sell a spaceship to the Glitzer people..."

Zhang Yuan frowned, thinking about the gains and losses. If he had to consume dozens and hundreds of years of development of the entire civilization just to gain some knowledge, then he had to consider whether it was cost-effective.

"If the benefits obtained are large enough, it is not impossible... but if it is just mathematical knowledge... it is not possible." He shook his head gently. Even though he was a mathematician, he was curious about the solutions to some mathematical problems. He could not betray the interests of the entire human civilization just because of curiosity.

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

After a while, Zhang Yuan spoke again: "His Excellency Gan Yaduo, I think you may have underestimated the difficulty of building a star-rated spacecraft. How big a spacecraft do you need? How many people do you carry, how far is it sailing? And the complexity of the ecosystem... How many production tools do you need to carry? These are all things that need to be considered."

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

Gan Yaduo said directly: "We have been thinking about this issue for a long time. Price is not a problem. As long as your civilization can be built... we can definitely pay this price!"

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

So much so that the entire negotiating team was a little confused and looked at each other, and was shocked by this.

"Wang Junpeng, what's the situation? Even I can't make the decision directly... Earth Age spent tens of millions of engineers on its productivity, and you know what the entire thirty years of construction is? We only have 500,000 people now..." Zhang Yuan asked softly in the headphones.

Wang Junpeng was also stunned. As the first batch of diplomats to come here, he was also stunned at this moment, "I do... don't know their true thoughts!"

Could it be that these Glitzers also want to imitate humans and colonize in deep space? This is incredible!

"They don't want this planet?"

“…”

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

The reward given by the other party is indeed extremely generous. It will not only give humans precious knowledge, including mathematics and common sense of cosmology, but also give away some valuable legacy left by alien civilizations!
