In addition to a large number of construction machinery, the second is to directly spend 3,200 amoeba points to buy a complete set of "strong logic robot automatic maintenance" system!

This is also known as the "Buy 100 Robots, Get the Complete Database" campaign. Those 100 robots are just small heads, equivalent to thousands of high-end maintenance personnel who don't need to rest or need entertainment.

More than 3,000 amoeba points, when he took out this point, Zhang Yuan felt that his heart was dripping blood!

The engineers were overjoyed, and one by one they began to work on robots, apparently quite satisfied with the deal.

The maintenance ability of this high-end robot is much stronger than that of robots developed by humans, which can effectively alleviate the problem of human lack of population!

The most important thing is that humans directly buy the library research rights of this type of robot, and can research, imitate, and improve it, so the value of this technology is so expensive.

Seeing the researchers full of fanatical emotions, Zhang Yuanqiang endured his heartache and comforted himself: "...... With this database, we can imitate this robot, although the imitation is necessarily not as good as the original at the beginning, but it can be improved! ”

"What's more...... Through this knowledge, we can find the truth to strong artificial intelligence. ”

"No loss, no loss, anyway, we definitely don't lose!"

As for the third, a number of nanobot industrial systems were purchased. The use of nanobots in the fourth-level civilization is too great, whether it is smelting minerals or synthetic materials, all nanobots can be used.

In particular, some high-end complex nanomaterials have no way to be smelted on a large scale like traditional materials.

It is necessary to rely on a large number of nanobots to "grow" slowly like cells to achieve molecular-level manipulation.

For this difficult technology, human beings have been studying it for a thousand or two thousand years, but they have found that it is still just getting started, and the relevant knowledge is still very lacking, so it is good to buy a little while the price is cheap.

These technologies are released by the trading market, full of weight, the probability of fraud in theory is very small, and the price is not too expensive, at least much cheaper than the robot database.

And the last part of the content, people have purchased a lot of obsolete spaceships and cheap weapons for various third-level civilizations.

There are many civilizations in this square, both third-level and fourth-level civilizations, and I heard that there are fourth-level civilizations that are buying obsolete weapons and equipment, and various third-level civilizations naturally flock to them, sell them in large quantities, and even start bargaining on the spot.

In the end, the people made a deal with a Level 3 civilization with two snail eyes.

In fact, these things are really cheap, as many Level 3 civilizations will leave after this sale. Before leaving, it's not bad to dispose of some of the excess garbage cheaply.

In this way, the silver was sprinkled like flowing water, and before I knew it, the accumulation of so many years was spent cleanly.

Many scientists are still lamenting that there are too few amoebic points in their hands, and they don't get what they want......

"Okay, okay, don't be so greedy, these things are enough for us to digest for a while."

Zhang Yuan shook his head, but he didn't think that the most valuable unique technology of human beings was the "extra perception" he had concocted. This is intellectual technology, something that many fourth-level civilizations do not have.

But selling this knowledge is risky, and in the future, without the constraints of a strong trading market, who knows if there will be any security incidents in the future?

So human beings only sell a small half, and this small half is just the study of additional colors, not additional magnetic field perception...... The best good things are not sold casually.

Although human beings crave amoeba points, they really don't dare to take them out and shout directly.

"Hello, dear new human civilization...... Once the machinery of your choice has been loaded, our transport ship will follow your ship and deliver it to the designated location. Said the artificial intelligence of the trading market.

"Thank you very much." Although the other party was just an artificial intelligence, the diplomats still greeted them very politely.

Immediately afterwards, Zhang Yuan waved his hand and greeted the scientists who were still visiting the robot.

"Alright, mission accomplished, let's go home!"

"It's faster, it's more important!"

This time, a lot of supplies were purchased, and there were 5 large transport ships piled up.

The ships of these exchanges followed right behind the human ships, moving unhurriedly.

There are also 7 transport ships of the third-level civilization, which are also following behind, and they are loaded with all kinds of obsolete weapons and various dilapidated spaceships.

As long as these things can be used, as for the performance, well, it is also a product of a third-level civilization, no matter how it is, it will not collapse too much...... Anyway, if it works, it's fine.

Zhang Yuan looked at the stars in the sky outside the window, and then looked at the people in the seats. The huge Dyson sphere, and the various transport ships in the vicinity were busy flying, suddenly giving birth to an indescribable sense of heaviness and urgency.

There was only one thought in his mind, there was a storm coming out of here, so he should hurry back and return to his mothership......

In this way, time passed day after day, and people couldn't help but cheer when they saw that familiar planet, as well as the six motherships nearby.

Zhang Yuan also clenched his fist vigorously.

This time the pressure was too great, but the final result was quite satisfying, and it could be regarded as a full load.

Don't just buy these things, it consumes most of the human heritage, and it will definitely be able to make the new human civilization go further!

"Good work!" Some of the greeters greeted smiling faces, and the captain's lady greeted the returning diplomats.

Engineers are busy unloading cargo from the ship in the rear.

They were all shocked when they saw several aliens from the third-level civilization following behind, coupled with the large amount of munitions loaded on the spaceship.

"What's going on? Why did you buy so many ...... like this" Captain Feng swallowed his saliva and asked in a slightly surprised manner, almost saying the word "junk goods".

"Plans have changed!"

Zhang Yuan whispered: "Hurry up and unload the goods!" Then let everyone check whether there is a spy program in it and whether there are any security risks. If so, make them lose money! While the trading market is still there! ”

"Okay, got it."

Although he still had some doubts in his heart, Captain Feng still asked the logistics department to carry out this task.

For a third-level civilization, the transaction of two hundred amoeba points is already a big deal, and it is actually selling arms to a fourth-level civilization, which sounds a bit unbelievable, these aliens are happy and have a good attitude.

On the other hand, Foreign Minister Mr. Yang announced the harvest of this trip during the working meeting.

However, in front of reporters, he temporarily concealed the news announced by the amoeba civilization, and it was estimated that it would take an hour or two to read the entire manuscript.

"Is there any other news, what the hell is going on with that amoeba civilization...... Also, so many low-quality arms were purchased...... What's going on? Captain Feng asked Zhang Yuan privately, and she had a bad feeling in her heart, and she was very concerned about this news.

"News, of course...... Not good news, though. ”

Zhang Yuan didn't sell it, repeated what he heard, and then spread his hands: "We can't afford high-quality arms, so we can only buy low-quality ones." Antimatter is even bought out of stock, and you can't buy it if you want to! ”

“…… Governors? The woman's heart trembled slightly.

A fifth-level civilization with a not-so-good reputation has actually become a galactic ruler, and there is a feeling that a storm is coming.
