Chapter 282 (1/2)

Before the catastrophe, the world's space industry has developed to an extremely considerable scale.

At that time, there were large space bases and space smelting workshops in Leo, synchronous orbit and airspace near the moon. Most of the special composite materials, precision instruments and core components of human society were produced and processed in these places.

The Holocaust destroyed the ecosystem of the planet, leading to the extinction of most human beings. However, most of these industrial bases flying in the sky have been preserved. It is because of the industrial and technological level of human civilization that there has not been a significant retrogression.

All kinds of materials that Qin Feng saw in the exhibition area, with their excellent characteristics, are basically in the imagination of scientists in the main world. How long will it take to become a reality.

In space, using microgravity and ultra vacuum environment, we can produce many kinds of materials which are difficult to produce on the ground or have low production efficiency, such as high purity bulk semiconductor crystals.

Another important production and processing field in space is alloy and special materials and products. Under microgravity conditions, new alloy structures and properties can be formed by means of miscible gap and vapor phase alloy processing. Solidification in space can even improve many properties of the alloy system.

In space, it can also produce excellent casting, ultra-thin film, high-purity materials, acid corrosion resistant materials, multi-performance materials (such as malleable tungsten). Porous materials such as foam plastics can be obtained. Foam steel can be as hard as steel on the earth, but the weight is light enough to float on the water surface.

This kind of special steel is absolutely impossible to make on the earth, because even if the steel is inflated into the molten steel, the gas will escape to the surface of the molten steel and evaporate away. Since the advent of communication satellite, optical fiber has caused the most profound revolution in the history of communication. However, the transmission distance and quality of optical fiber signal have a great relationship with the purity of glass fiber. In space, high-quality optical fibers of high purity can be produced.

The Russians used to produce semiconductor crystals inside the space station and made profits. In the 1980s, the most important job of the American space shuttle was to bring the ESA space laboratory to produce protein crystals.

It is generally accepted that space industrialization can revolutionize the important high-tech field material science. Materials technology is the basis of all other applied technologies.

After consideration, Qin Feng decided to buy all the 100 tons of rhenium. Other kinds of mineral materials, as long as they are not available in the territory, will eat at least half.

Of course, the importance of these things is less important than that of talents and equipment. Therefore, Lin Xihan just input the price and purchase intention on the light screen, and no longer let the person in charge of the chamber of Commerce publicly bid.

When he came to the innermost part of the exhibition area, he found that it was empty. A thin, ugly little girl was sitting on the ground with her legs crossed and her eyes closed.

Qin Feng was a little surprised. He glanced at him at will and waited to turn around and leave. He thought that something was wrong.

He squatted down, quietly launched the ability, staring at the girl, carefully sensed for a while, and slowly became dignified.

”Your Highness...”

Lin Xihan beside him has some doubts. Does Qin Feng like this type? However, the girl's dress is ordinary, her appearance and body are very ordinary, and she has no evolutionary potential. She is totally incomparable with those beautiful and shining women before. I really don't know how she came here.

Just at this moment, the girl opened her eyes and looked at Qin Feng for a moment. Her tone was indifferent and she said, ”you're here at last. Take me and give him one billion yuan by the way.”

She was referring to the head of the chamber of Commerce.

Qin fenglue pondered, then nodded and agreed: ”yes.”

Lin Xihan's eyes widened. The price of the most excellent female slaves on the scene is only tens of millions. The girl's mouth is about one billion? Who do you think you are?

”What's going on?” She asked crossly.

The person in charge of the chamber of Commerce quickly explained: ”Your Highness, this girl was picked up from the wilderness by accident more than half a year ago. At that time, she helped me, and then asked me to send her to Send it to the southeast of the mainland. ”

Qin Feng's face moved. It was her own territory. Did she come for her own sake?

It seems to make sense, but she was still in the main world at that time, and the incarnation was sleeping at that time, so she didn't find anyone. After coming back, she didn't stop very much, so she had no chance to find herself.

The words of the person in charge of the chamber of Commerce confirmed his inference: ”she seems to want to see someone, but she doesn't say who it is. Later, she went back to Wangdu with me and said that sooner or later she would meet the person she was looking for, and then I could get a billion yuan reward?”

Lin Xihan sneered: ”I remember that you have always been very smart. How can you believe such unreliable lies? It seems that my father made you take charge of the business affairs of the chamber of Commerce. It's really a mistake. ”

”Your Highness, it's not like this. I'm...”

The person in charge of the chamber of Commerce was embarrassed and didn't know where to start.”Forget it, a billion is a billion.”

Qin Feng winked at Lin Xihan: ”give him the money, and we will leave immediately.”

Of course, he could see that the person in charge of the chamber of Commerce was indirectly affected by the girl's uncanny mental strength, otherwise he would not agree to such an almost absurd request.

”Good, good.”

Lin Xihan is full of doubts, but still agreed to come down. She didn't want to upset Qin Feng, but she didn't pay for it.

In fact, from Qin Feng's point of view, it's worthwhile to spend a hundred times the price to replace this little girl, not to mention a billion yuan. Of course, there is no need to explain this to others.

The girl stood up slowly, intending to take his hand, and hesitated a little: ”you won't eat me, will you? I'll give you more. ”

”Of course not.”

Qin Feng gentle way, holding her little hand in his palm.

Lin Xihan was at a loss when he heard this, but it was not easy to ask more questions in full view of the public. He could only wait until he went back.
