Everyone looked at the distant alien spacecraft, and people discussed the signed regulations, plus the free curvature knowledge.

This knowledge is the dream of three-level civilization, which may take thousands of years or tens of thousands of years to pursue.

But now, as long as mankind signs a treaty, it can be obtained, and it is a complete set of system theory. Relying on this set of theory, it can directly reach three times the speed of light.

This psychological feeling is really hard to describe, how to say... Recalling those experiences in the past, science and technology is not the most precious, but spiritual wealth is more precious. Zhang Yuan shook his head gently. Anyway, only relying on himself is the right choice.

Several relevant scientists are discussing various formulas and theorems in the spacecraft. They are using computers to verify them.

"How's it going? This formula... Should be a variant of our rotation formula. "

"Yes, it looks different, but it's actually the same."

"And this parameter is slightly different from ours. Let's simulate it with a computer."

A few hours later, they came to a general conclusion.

"This knowledge is mainly biased towards theory. We have obtained most formulas without errors. But there is still a small part that we don't have... "

One of the diplomats said, "these free gifts are all the contents of rotten streets. Don't we have them?"

"Yes, we really don't have this part of knowledge..." the scientist said very seriously: "this is a new discipline. There are many things that look very simple to each other, but we haven't sorted them into a system."

"This is the benefit of interstellar communication. One civilization always has limitations, while two civilizations still have limitations. Our current population of 150 million is not enough... "

"However, there is no need to be discouraged."

Zhang Yuan nodded, smiled and said: "this is a larger trading market, which attracts thousands of light-years of civilization around. There must be no shortage of four-level civilization here. We are not strong, but we are not weak. First of all, we should show our attitude..."

"We should stay here for a period of time. After all, we can explore more things and learn more."

In this way, after finishing this matter, the party first rested in the Embassy of the trading market for a while, and then reported their security status to the rear.

And transferred the knowledge just got back.

Finally, it is to apply to the rear area for a transport spacecraft to carry the engineering equipment of each station to Dyson ball and establish a real embassy, rather than now. It is too shabby to use a spacecraft as a facade.

After finishing all the work, I had a little rest for half a day

On the next day, the soldiers attacked in several ways. Some were responsible for looking for aliens for commercial negotiations, while others were responsible for scientific and technological exchanges, political negotiations and signing agreements with alien civilizations.

It has to be said that there are many agreement organizations in this market, such as scientific and technological exchanges, industrial production and cultural exchanges, as well as debt swap organizations, that is, a large number of civilization with credit owed to the trading market, which can borrow and repay their debts.

Any civilization with excess productivity can be sold to this organization. If the productivity of a civilization is not enough, and the task has to be delivered in time, you can also buy productivity here.

If humans are too lazy to dig war stars, they can also buy productivity and let other civilizations dig them. The price of labor and productivity is also clearly marked.

There are also some scientific and technological standard setting organizations, which are more ambitious scientific research institutions.

Most civilizations developed independently from ancient times. Under the long exploration, the scientific and technological standards are different, which makes the scientific and technological exchange between them very troublesome.

This is just like the electrical standards of various countries in the earth period. Some countries stipulate that the voltage is 220 volts, while others stipulate that the voltage is 110 volts. These electrical appliances cannot be used in common with each other. The distance between railways in different countries is different. When the train reaches the boundary line, it can't continue because the railway becomes wider or narrower.

There are also different races, cultures and languages. It is also called "diversity"

But in a word, with a general standard, communication will be much smoother, and most things can be used directly. Some aliens also came to lobby. If the new human civilization joins this kind of scientific and technological standards organization, it will get a series of benefits.

Its prosperity is an eye opener, far beyond the Huantai civilization trading market we have visited!

There are even some military alliances that invite mankind to join the United Front. As long as an agreement is signed, its simplicity is simply amazing and difficult to understand. After joining this kind of military alliance, we can develop military spacecraft with each other to deal with the chaos after the market relocation.

Of course, this kind of military alliance, people certainly can not sign indiscriminately, even if its binding force is not strong, there seems to be no trap. Human beings are new here and get too little information. Why form a military alliance with others?

Moreover, it has exposed the performance parameters of its own spacecraft. It is relatively not a wise choice to choose joint development.

At present, people can only trust the "TOS civilization" that has worked together for thousands of years. Because people have a deep understanding of TOS civilization and have a lot of cultural exchanges with each other. Moreover, the two sides can only form a semi military alliance at most. They are independent of each other. It is impossible for one party to command the other

It's strange to join this inexplicable Alliance

Time gradually passed. In a month, mankind had a general understanding of the trading market.

The Dyson ball is too big. It's really indescribable. It's so huge that any building and spacecraft can fly around

The host of the trading market is jihaman civilization. The population of this five-level civilization is not very large. They almost devote all their energy to the vast construction of Dyson ball. They don't have much time to manage the market, so they form so many non-governmental organizations.

This decentralization is the first time that people have encountered it. It seems different from the original Huantai civilization trading market

"So many civilizations come together and only communicate without war, so they begin to grow savagely!"

Zhang Yuan dares to be sure that there are many swindler civilizations inside, which contain a huge number of traps. Agreements cannot be signed arbitrarily.
