After this announcement, each civilization will have the option to go to the "F-203" area to participate in the final sale, and there is no limit to the number of places to be sold.

Because the Dyson sphere is so large, you still have to use a transport spacecraft to get to your destination.

The ion engine slowly spewed flames, and for some reason, Zhang Yuan always had a sense of uneasiness in his heart...... Probably because of the instinctive uneasiness caused by the imminent departure of the absolutely neutral amoeba faction.

A new human civilization with a high degree of trust is about to disappear, and the new human civilization that has not experienced many wars is like a flower in a greenhouse.

"Actually, it's not just us, most civilizations have not experienced many wars."

"I even think that the reason why there are so many sinker civilizations is because everyone is so comfortable."

"You're right, but you're not right." Zhang Yuan said: "Fighting a war can force a civilization to develop forcibly from external factors, but it cannot promote the progress of a civilization from within. ”

A few hours later, the high-speed spacecraft arrived in a mega-plaza of one million square kilometers. Looking down from the top of the spaceship, the square is divided into a total of 1,202 squares, which are densely packed with mechanical equipment, some of which are even the size of a mountain!

Under the guidance of local artificial intelligence, people parked their ships and received a series of transaction forms.

[Dear New Human Civilization, Hello! This information is the list of goods traded. 】

[In this square, the price of all the supplies has been marked, you can see the equipment up close and choose to buy it.] 】

[In the F-208 area, the Amoeba civilization is celebrating the official completion of the Dyson sphere.] Your civilization can also go to the relevant rituals on their own. 】

Zhang Yuan visited the "Micro and Nano-Alpha 3 Maintenance Robot" in front of him, which is very large, as tall as an elephant, and has a total of 12 mechanical arms.

Looking at the specific parameters, Zhang Yuan praised in his heart that this robot can repair mechanical devices with a complexity of "D99G0" or less.

This kind of robot, which can realistically make complex logical judgments, involves some key areas in the field of artificial intelligence.

When designing a maintenance robot, there is a general principle: the complexity of designing a certain maintenance robot is higher than the object itself that needs to be repaired.

For example, humans can design a robot that repairs a washing machine, because the construction principle of the washing machine is simple, the number of parts is small, and the robot can judge those areas that are damaged.

If the complexity of the washing machine is 1, then the difficulty of the robot that repairs the washing machine may become 10.

The difficulty of 10 is still within the acceptable range of humans.

So, what about machines that are orders of magnitude more complex than washing machines?

Take, for example, excavators. The difficulty of designing an excavator is 20, so the difficulty of the robot that maintains the excavator may soar to 100, and it is impossible to let the robot that repairs the washing machine repair the excavator.

In other words, the more complex the machine, the more difficult it is for the robot to repair such complex things.

Of course, with human capabilities, this excavator maintenance robot can still be designed. It is precisely because of these guys that they helped mankind complete the original neutron star collision project.

But what about orders of magnitude more complexity? For example, the robot that repairs the robot, and the spaceship Qicheng, the complexity becomes 100 million!

There are tens of billions of parts and components of this spaceship, and there are hundreds of engineers responsible for design and maintenance, involving more than 300,000 related personnel!

This kind of ultra-difficult cutting-edge technology can only be maintained by humans themselves, and it is no problem for robots to be assisted, but it is absolutely impossible to complete it automatically.

The main reason is that humans can't design such ultra-intelligent robots.

It's already hard to design a spaceship, and it's hard enough to design a robot that maintains a spaceship, and I don't know how many orders of magnitude more difficult it's anymore...... When the engineers slowly design such a maintenance robot, tens of thousands of years later, this spaceship will be eliminated!

The design of complex maintenance logic is even more troublesome than the education of infants and young children. Because the education of infants and toddlers is troublesome, but it can be exhaustive, theoretically everyone is unique, but there have been so many human beings in the world, there is nothing new under the sun, there have been people similar to you in history, and there is enough data in the database......

Therefore, a robot teacher plus a small number of human teachers can complete the education of a large number of children.

But the maintenance robot is not good, and some broken parts are better than remanufacturing one......

Therefore, this kind of "micro-nano-alpha-3 maintenance robot" produced by the fifth-level civilization is quite attractive to humans.

[Micro and nano-alpha 3 maintenance robot, remaining quantity: 19009829, price: 32 amoeba points/unit. 】

[The rules of use are as follows......]

[If you buy 100 robots, you will be able to access the robot database.] 】

This robot is capable of maintaining mechanical devices with difficulty of "D99G0" or less, and as long as the drawings of the machinery are entered into its database, the robot can master the maintenance skills, which is very convenient.

"D990G0" is a calculation standard in the trading market, which should be understood by a professional engineer. The first symbol is worth becoming

Zhang Yuan knew that it was a calculation standard anyway, but he didn't know how to calculate it.

The trading market also stipulates the specific use of this robot, which can only be used, not cracked, as if forcibly cracking its artificial intelligence, the robot will directly self-destruct.

If you want to buy a database for a robot, the price will increase significantly.

"Compare its features, the price of 32 ......"

Zhang Yuan felt in his heart that the price was actually okay, but it was still a little expensive for the entire new human civilization, and it was no problem to buy one or two, but he couldn't afford to buy too much.

This kind of robot, if it is not large-scale, is actually not much use. The maintenance capacity of a few senior engineers can be compared to a robot, so why spend money on it?

In this way, I visited several batches of robots one after another, all of which are far ahead of the fourth-level civilization in the field of automatic intelligence, and the materials are average, and nothing is beyond imagination.

"This damn market is opening its mouth in the lion's mouth! There are more than 30 amoeba points for a robot, and there are 19 million units in total! This thing can be made infinitely, why is it so expensive? "An engineer is sighing, it's too expensive, it's really too expensive, and I can't do it when I see so much inventory.

"People are a fifth-level civilization, of course it's easy to make money...... Especially the money of the more low-level civilization. ”

"Haven't you heard the allusion to 800 million shirts for an airplane?"

"Lao Zhang, let's go! The spaceship is coming! Lao Yang greeted and left more than 200 engineers to inspect the vicinity.

"You investigate here first, and we'll go around the other places."

"No problem."

The place they are heading to is the completion site of the Dyson Sphere to see the legendary sixth-level civilization!

After boarding the large transport ship dedicated to the Dyson Sphere, Zhang Yuan found that the other boxes were full of strange-shaped aliens, some looked like orangutans, some looked like stones, and some were fully armed by machinery, and they couldn't see the specific appearance.

Everyone belongs to the boxes of their respective civilizations, and they can only be seen through the transparent cover when they get on and off the ship.

Since there have been so many aliens he has seen over the years, Zhang Yuan didn't care too much about anything, just closed his eyes and recuperated himself.

After another half a day, the spaceship came to a new venue, and people had a glass room of their own civilization.

Before he had time to get off the spaceship, Zhang Yuan saw the true face of the "amoeba civilization" through the window!
