The number of war stars that a civilization can bear is limited. With the huge size of the planet, the number of machines may reach tens of billions, requiring a large number of engineers to maintain all aspects.

The conventional civilization usually does not have unlimited population, so it will not have unlimited development of war stars.

All in all, after all these years, it is a good thing that there is finally a civilization willing to sell the extra planets. As the other side's asking price is relatively high, both sides are still bargaining.

Zhang Yuan exhaled a breath of turbid air in his chest. Looking at the data on hand, he found that the mass of this planet is about the size of the moon, and its density is about 8.2 tons / cubic meter, which is a little higher than that of iron, which means that it is completely a large piece of metal.

This kind of planet is often quite good in texture, and its mechanical structure, mineral composition and anti Strike ability are better than ordinary planets.

The human scientists are still in the process of geological investigation.

Of course, a primitive planet alone can't sell at a very good price. There are so many primitive planets in this starry sky, and no one wants any raw materials at all!

The key point is that hemispheric civilization has been developed here for more than 1500 years, digging the foundations of planetary engines, residential areas and industrial areas, but it has not yet begun to build.

This is exactly what people want. If everything is built, people will not want it. Because this Planetary Fortress is intended to be the main base of human beings. If you use other people's equipment, it always feels very strange and unsafe So in the end, it will be demolished and rebuilt, and the workload will be increased for no reason.

Now it's more appropriate to dig a foundation like this.

Because of this, after hearing the news, Zhang Yuan was in a good mood. After work, he specially bought a kilo of "sweet and sour grass" as a fruit for the banquet.

This is the latest antioxidant food from other civilizations. It is said that long-term use can prolong human life.

Well, this kind of antioxidant food, just like all kinds of health care products, is too many to count. Zhang Yuan doesn't know whether this kind of rumor about "improving life expectancy" is correct.

Anyway, it's harmless, expensive and delicious!

When I got home, I found that my wife, Lin Xuanxuan, was happily cooking dinner, which was quite rare. They are both members of the embassy. They will stay here for about five years. Their work is very busy at ordinary times. Today is their third year here

Zhang Yuan arranged the fruit on the fruit plate, and then smelled the fragrance from the kitchen, and his stomach called a few times.

There is no doubt that Lin Xuanxuan's cooking skills are excellent, but she is usually too lazy to cook herself. As for today, of course, there are guests to visit!

Smelling the taste of the dishes, Zhang Yuan can't help but sneak into the kitchen and eat a chicken wing. Then he is beaten by his wife.

He felt a little embarrassed: "if you dare to hit me, I will kill you today!"

"Kill what ring ah, don't get in the way here!"

I heard the doorbell again and rushed to open the door.

It was a group of dusty diplomats standing at the door, all of whom were invited to this banquet, with a total of seven or eight people.

Two scientists have just inspected the Planetary Fortress provided by hemispheric civilization.

"Come in, come in!" Zhang Yuan said with a smile.

This kind of private banquet, only friends with good friendship will be invited. We have worked with each other for many years, and the atmosphere is very harmonious.

At 6 p.m., it's very interesting for us to enjoy the delicious food, chat and talk about the alien civilizations near Dyson ball.

“…… Some civilizations are stubborn and insist on one thing to the end; others are strong and don't want to lose anything in the negotiation, just want to take advantage of it. "

"There are also civilizations. When negotiating, they talk about everything. Before getting down to business, they talk about" what did you eat today "," cultivated a precious alien plant "and so on, which makes people feel quite at a loss."

“…… However, what these four civilizations have in common is that their inborn race value is much higher than ours. In my opinion, in the process of development, we may not have suffered more than us. "

Several diplomats shared their views with each other.

"That's not necessarily. It's just your intuitive feeling. You don't have a deep understanding of these alien civilizations We got the clue of curvature technology by chance, and these civilizations may have been explored by ourselves in the dark fog. This is a great thing. "

"Being able to become a four level civilization has its own advantages, whether in terms of inborn race value or social system Oh, by the way, there are some four level civilizations, which are fostered by other civilizations. Their social system is not very good, but their racial values are very high. "

"In a word, our race value must be the lower one..."This racial value refers not only to intelligence, but also to ideology, perception, life span and other factors. If so, Zhang Yuan also thinks that human race value is not very high

But there's no way. Race value is a natural thing. It's hard to change.

Zhang Yuan gave a dry smile: "low race value also has the advantage of low race value. There is more room for improvement! Our social system is very advanced, perhaps more advanced than other civilizations. "

But if we can find a way to enter the fifth level civilization, these innate things will become irrelevant

"And the four civilizations that have been fostered?"

"Of course, there are, and there are a lot of them, which is equivalent to subsidiary civilization. These are all the hearsay we have heard. We can't get to know so many civilizations in depth. "

"What about the NPT? Does it apply to subsidiary civilizations? "

"I don't know."

For a moment and a half, everyone fell into silence. Judging from the current intelligence, the gap between the four civilizations is really huge! Some of the subsidiary civilizations of civilization have risen to the fourth level.

Zhang Yuan suddenly asked, "let's talk about the war star How is the negotiation going? Recently, people are calling for a Planetary Fortress. "

In fact, when the government announced this big project, people's attention was always high. No matter how many Internet polls are launched, they are overwhelming support Even if the plan is difficult.

Even if it is a Titan class spacecraft, compared with the real planet, it is still far worse!
