After this notice, each civilization can choose to go to the "F-203" area to participate in the final sale, with no quota.

Due to the huge size of the Dyson ball, it is still necessary to use a transport spaceship to reach its destination.

The ion engine is slowly spraying flames. I don't know why, Zhang Yuan always has a sense of uneasiness It may be because of the instinctive uneasiness brought about by the impending departure of the absolutely neutral amoeba faction.

A highly trusted umbrella is about to disappear. The new human civilization, which has not experienced many wars, is like a flower in a greenhouse.

"It's not just us. Most civilizations don't experience many wars."

"I even think that the reason why there are so many degenerate civilizations is that we are too comfortable."

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

A few hours later, the high-speed spacecraft came to a mega square of one million square kilometers. Looking down from the top of the spaceship, the square is divided into 1202 squares, which are densely packed with mechanical equipment, some of which are even the size of a mountain peak!

Under the guidance of local AI, people stop their spaceships and receive a series of transaction forms.

[dear new human civilization, Hello! This information is the list of goods and materials to be traded. 】

[in this square, the prices of all materials have been marked, so you can visit these equipment in close range and choose to buy them. 】

[in the f-208 region, the amoeba civilization is celebrating the official completion of Dyson sphere. Your civilization can also go to the relevant ceremonies by itself. 】

Zhang Yuan visited the "micro nano alpha 3 maintenance robot" in front of him, which is as big as an elephant, with a total of 12 robotic arms.

Looking at the specific parameters, Zhang Yuan praised in his heart that this robot can repair mechanical devices with complexity below "d99g0".

This kind of robot, which can judge the complex logic of reality, involves some key areas in the field of artificial intelligence.

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

For example, human beings can design robots to repair washing machines. This is because the washing machine has a simple structure and a small number of parts. If the parts are damaged, the robot can judge.

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

The difficulty of 10 is still within the range of human acceptance.

So, how many orders of magnitude more complex than a washing machine?

For example, excavators. The difficulty of designing a excavator is 20, so the difficulty of maintaining the excavator robot may soar to 100. It is impossible for the robot repairing the washing machine to repair the excavator.

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

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

But how many orders of magnitude more complex? For example, a robot that repairs a robot, or a spaceship like the departure, has a complexity of 100 million!

There are tens of billions of spare parts for this spaceship, and there are hundreds of engineers responsible for design and maintenance, involving more than 300000 relevant personnel!

This kind of super difficult cutting-edge technology can only be maintained by human beings. It's no problem for robots to be used as AIDS, but it can't be fully automatic.

The main reason is that humans can't design this kind of super intelligent robot.

It's very difficult to design a spaceship. It's a few orders of magnitude more difficult to design a robot to maintain the spaceship. There's nothing we can do When 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 infant education. Although infant education is troublesome, it can be exhaustive. In theory, everyone is unique. But there are so many human beings in the world. There is nothing new in the sun. There have been people like you in history, and there are enough data in the database

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

But the maintenance robot is not good. Some parts are broken. It's better to make a new one

Therefore, the "micro nano alpha 3 maintenance robot" produced by the five level civilization is quite attractive to human beings.

[micro nano alpha 3 maintenance robot, remaining quantity: 19009829, price: 32 amoeba points / set. 】[the rules are as follows 】

[if you buy 100 robots, you will get the access to robot database. 】

this kind of robot can maintain the mechanical devices with difficulty less than "d99g0". As long as the mechanical drawings are input into its database, the robot can master the maintenance skills, which is very convenient.

"D990g0" is a calculation standard in the trading market, and professional engineers should be able to understand it. The first sign value is

Zhang Yuan knows that it is a calculation standard, but he doesn't know how to calculate it.

The trading market also stipulates the specific use of this robot, which can only be used, but can not be cracked. Just like breaking its artificial intelligence, this robot will directly self destruct.

If you want to buy a database of robots, the price will increase significantly.

"Compared with its function, 32's price..."

Zhang Yuan thinks that the price is OK, but it's still a little expensive for the whole new human civilization. It's no problem to buy one or two. If you buy too many, you can't afford it.

This kind of robot, if not in scale, is not very useful. The maintenance ability of several senior engineers is comparable to that of a robot. Why should we pay for it?

In this way, I visited several batches of robots in succession, all of which are far ahead of the fourth level civilization in the field of automatic intelligence. The materials are ordinary, and nothing is beyond imagination.

"This damned trading market is open to lions! A robot has more than 30 amoeba points, a total of 19 million! This thing can be made infinitely. Why is it so expensive? " An engineer is sighing, too expensive, really too expensive, see so much inventory, simply can't start.

"People have a five level civilization, so it's easy to make money Especially the lower civilized money. "

"Haven't you heard the story of 800 million shirts changing for an airplane?"

"Lao Zhang, let's go! Here comes the ship Lao Yang said hello and left about 200 engineers to inspect the area.

"You'll study here first, and we'll go to other places."

"No problem."

The place they are going to is the completed venue of Dyson ball. Let's see the legendary level 6 civilization!

After boarding the special large transport ship of Dyson ball, Zhang Yuan found that all the other boxes were strange shaped aliens. Some looked like orangutans, some looked like stones, and some were fully armed with machinery, so he could not see the specific appearance.

We all belong to the boxes of our respective civilizations. Only when we get on and off the spaceship can we see through the transparent cover.

Due to the fact that there are so many aliens I've seen in recent years, Zhang Yuan doesn't care much about anything, but just keeps his eyes closed.

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

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