In addition to a large number of construction machinery, the second is to directly spend 3200 amoeba points to buy a complete set of "strong logic robot automatic maintenance" system!

That is the so-called "buy 100 robots and give a complete database" activity. Those 100 robots are just small heads, equivalent to thousands of high-end maintenance personnel who don't need rest and entertainment. The knowledge they buy is the real big head, almost out of blood!

More than 3000 amoeba points ah, when he took out this point, Zhang Yuan felt his heart dripping blood!

But those engineers were happy and began to study robots one by one. It was obvious that they were quite satisfied with this deal.

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

The most important thing is that human beings have directly bought the program library research permission of this kind of robot and can study, imitate and improve it. Therefore, the value of this technology is so expensive.

Seeing the researchers full of fanaticism, Zhang yuanqiang endured heartache and comforted himself: "... With this database, we can imitate robots in this field. Although the imitation must not be better than the original at the beginning, it can be improved!"

"More importantly... We can find the truth to strong artificial intelligence through this knowledge."

"No loss, no loss. Anyway, we must not lose!"

As for the third, we bought some nano robot industrial systems. The use of nano robots in the fourth civilization is too great. Nano robots can be used in smelting minerals and synthetic materials.

In particular, some high-end complex nano materials can no longer be smelted on a large scale like traditional materials.

We have to rely on a large number of nano robots to "grow" slowly like cells in order to achieve molecular level control.

For this difficult technology, humans have studied it for one or two thousand years, but they still find that it has just started, and the relevant knowledge is still very lacking, so it's good to buy it at a low price.

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

In the last part, people have purchased many obsolete spaceships and cheap weapons towards various three-level civilizations.

There are many civilizations in this square, including three-level civilization and four-level civilization. It is said that four-level civilization is purchasing eliminated weapons and equipment. Naturally, all three-level civilizations flock to sell in large quantities, and even start bargaining on the spot.

Finally, people made a deal with a tertiary civilization with two snail eyes.

In fact, these things are really cheap, because many tertiary civilizations will leave after this sale. Before leaving, it's good to dispose of some redundant garbage cheaply.

In this way, the silver was scattered like running water. Unconsciously, all these years of savings were spent cleanly.

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

"Well, well, don't be so greedy. These things are enough for us to digest for some time."

Zhang Yuan shook his head, but he didn't think so. The most valuable unique technology of mankind is his "additional perception". This is intellectual technology, something that many fourth level civilizations have never owned.

However, there are risks in selling these knowledge. In the future, without the restriction of a strong trading market, who knows if there will be any safety accidents in the future?

Therefore, humans only sell a small half, which is only the research of additional colors, not additional magnetic field perception... The top good things will not be sold casually.

Although human beings are eager for amoeba points, they really don't dare to take them out directly.

"Dear new human civilization, hello... The mechanical equipment you selected has been loaded. Our transport spacecraft will follow your spacecraft and send it to the designated location." The artificial intelligence of the trading market said.

"Thank you very much." Although the other side was only an artificial intelligence, the diplomats still said hello very politely.

Then Zhang Yuan waved and greeted the scientists who were still visiting the robot.

"Well, the task is completed, let's go home!"

"Speed up, and there are important things!"

This time, we bought a lot of materials, enough to pile up five large transport spacecraft.

These exchange ships are moving slowly behind the human ships.

There are also seven transport ships of class III civilization, which are also followed behind, filled with all kinds of obsolete weapons and all kinds of dilapidated ships.

As long as these things can be used, as for the performance, well, at least they are products of three-level civilization. No matter how, they won't collapse too much... They can be used anyway.

Zhang Yuan looked at the stars outside the window and at the people on the seat. The huge Dyson ball and all kinds of transport spacecraft nearby are busy flying, suddenly giving birth to an indescribable sense of heaviness and urgency.

There is only one thought in his mind. There will be a storm here soon. Hurry back and go back to his Mothership

In this way, time passed day by day. When people saw that familiar planet and six nearby motherships, they couldn't help cheering.

Zhang Yuan also shook his fist hard.

This time the pressure is too great, but the final result is still satisfactory. It can be regarded as a full load.

Don't look, just buying these things consumes most of mankind's inside information. It will certainly make the new human civilization further!

"Hard work!" Some welcoming personnel greeted with smiling faces, and the captain's lady was also welcoming these returning diplomats.

Engineers are busy unloading cargo from ships in the rear.

When they saw several aliens of three-level civilization following behind, plus a large number of arms loaded on the spacecraft, they were all shocked.

"What's going on? Why did you buy so many of these... "Captain Feng swallowed his saliva and asked in a little surprise, almost saying the word" junk goods ".

"The plan has changed!"

Zhang Yuan said quietly, "unload the goods quickly! Then let everyone check whether there are spy programs and potential security risks. If so, let them lose money! While the trading market is still there! "

"OK, I see."

Although there was still some doubt in his heart, Captain Feng still asked the logistics department to carry out this task.

For the third level civilization, the transaction of 200 amoeba points is already a big deal, and it sounds a little strange to sell arms to a fourth level civilization. These aliens are happy and have a good attitude.

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

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

"Is there any other news? What's the matter with the amoeba civilization... And what's the matter with buying so many low-quality arms?" Captain Feng asked Zhang Yuan privately. She had a bad feeling in her heart and was very concerned about the news.

"Of course there is news... But it's not good news."

Zhang Yuan didn't show off either. He 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 out of stock. You can't buy it if you want to! "

"... the governor?" The lady was thrilled and her whole body trembled slightly.

A five level civilization with a bad reputation has become a galactic ruler. It's almost like a storm.
