Before the catastrophe, the space industry in this world had developed to a stage of extremely considerable scale.

At that time, there were large space bases and space smelting factories in low-Earth orbit, synchronous orbit, and the 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 catastrophe destroyed the planet's ecosystem and led to the extinction of most humans. However, most of these industrial bases flying in the sky were preserved. This is why the industrial technology level of human civilization has not suffered a major setback.

The various materials Qin Feng saw in the exhibition area had extremely excellent properties. In the main world, they were basically imagined by scientists. It was not known how long it would take to become a reality.

In space, microgravity and ultra-vacuum environments can be used to produce and synthesize many kinds of materials that are difficult to produce or have low production efficiency on the ground, such as large semiconductor crystals with extremely high purity.

Another important field of production and processing in space is alloys and special materials and products. Using miscibility gaps and vapor phase alloy processing methods under microgravity conditions will form new alloy structures and properties. Solidification that occurs in space

The phenomenon even improves many properties of the alloy system.

Castings with excellent performance, ultra-thin films, high-purity materials, acid corrosion-resistant materials, multi-performance materials (such as malleable tungsten), etc. can also be produced in space. Porous metal materials like foam plastics can be obtained, and foam steel can be produced like foamed plastics.

Steel on Earth is as hard as steel, but light enough to float on water. This kind of special steel can never be made on Earth, because when steel is made, even if gas is added to the molten steel, the gas will escape into the molten steel.

Surface, evaporate away. Since the advent of communication satellites, optical fiber has caused the most far-reaching revolution in the history of communications. However, the distance and quality of optical fiber signal propagation are closely related to the purity of the glass fiber.

.And in space, high-quality optical fibers with extremely high purity can be produced.

The Russians once produced semiconductor crystals in the space station and made a profit. The most important work the Americans did on the space shuttle in the 1980s was to take the European Space Agency's space laboratory to space to produce protein crystals.

It is a generally accepted view in the main world that space industrialization can bring about revolutionary changes in the important high-tech field─materials science. Materials technology is the foundation of all other applied technologies.

After consideration, Qin Feng decided to buy all the one hundred tons of rhenium metal. As long as other types of mineral materials were not available in the territory, he would buy at least half of them.

Of course, the importance of these things is relatively inferior to that of talents and equipment, so Lin Xihan just entered the price and purchase intention on the light screen, and no longer let the person in charge of the chamber of commerce make a public bidding.

When he came to the innermost exhibition area, he found that it was empty. A thin and unattractive little girl sat cross-legged on the ground alone, closing her eyes and thinking.

Qin Feng was slightly surprised. He glanced at it casually and turned to leave. After thinking about it, he felt something was wrong.

He squatted down and activated his ability quietly. He stared at the girl carefully for a while, and his expression gradually became serious.

"Your Highness, you..."

Lin Xihan next to her was a little confused. Could it be that Qin Feng liked this type? But this girl was dressed in ordinary clothes, had an average appearance and figure, and did not have the potential to be an evolver. She was completely different from the previous beautiful and radiant women.

It's beyond comparison. I really don't understand how she could appear here.

At this moment, the girl opened her eyes, looked at Qin Feng for a moment, and said indifferently: "You are finally here, take me away, and give him one billion by the way."

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

Qin Feng thought for a moment, then nodded and agreed: "Okay."

Lin Xihan's eyes widened. The most outstanding female slave on the scene was only worth tens of millions, but this girl asked for a billion? Who do you think you are?

"What's going on?" she asked displeasedly.

The person in charge of the Chamber of Commerce quickly explained: "Your Highness, it's like this. I accidentally picked this girl up from the wilderness more than half a year ago. She did me a favor and then asked me to send her... to the southeast of the mainland.

Let’s go.”

Qin Feng's expression moved slightly. That was his territory. Did she come here just for him?

It seems to make sense, but she was still in the main world at the time, and her incarnation was sleeping at that time, so she didn't find anyone. After she came back, she didn't stay long before leading the army to fight against the Rot Claw Lizardmen, and it was even less likely that she would have the chance to come.

Looking for myself.

The words of the person in charge of the Chamber of Commerce confirmed his inference: "She seemed to want to meet someone, but she didn't say who it was. Later, she returned to the capital with me and said that sooner or later she would meet the person she was looking for.

Then I can get a reward of one billion?"

Lin Xihan sneered slightly: "I remember you have always been very shrewd, but you actually believe such unreliable nonsense? It seems that my father made a mistake in letting you take charge of the Chamber of Commerce's errands."

"Your Highness, that's not the case, I..."

The person in charge of the Chamber of Commerce looked embarrassed and didn't know where to start.

"Forget it, one billion is just one billion,"

Qin Feng winked at Lin Xihan: "Transfer the money to him and we will leave immediately."

Of course he could see that the person in charge of the Chamber of Commerce was indirectly affected by this girl's ridiculously strong mental power, otherwise he would not agree to such an almost ridiculous request.

"Okay, okay."

Lin Xihan was full of doubts, but she agreed anyway. She didn't want to make Qin Feng unhappy, and it wasn't her own money anyway.

In fact, from Qin Feng's point of view, it is worth spending hundreds of times to exchange for this little girl, let alone one billion. Of course, there is no need to explain this to outsiders.

The girl slowly stood up and planned to hold his hand, but hesitated a little: "You won't eat me, will you? I will give you more."

"of course not."

Qin Feng said gently, taking her little hand and placing it in his palm.

Lin Xihan was confused after hearing this, but it was difficult to ask too many questions in front of everyone, so she could only wait until she got back.

When a group of people arrived at the exit of the venue, someone suddenly shouted: "Wait!"

Immediately afterwards, a large group of people rushed over, led by the two white Westerners with blond hair and blue eyes, blocking the path of Qin Feng and Lin Xihan.

"What are you going to do?" Lin Xihan's face turned cold.

She could see that these two guys were not qualified to enter the trading place on the top floor, so they had been waiting at the door for a long time.

"Is such that……"

One of the guys saluted and said hurriedly: "Your Excellency, Pabor, this little girl is the daughter of an old friend I have been looking for. Could you please make it convenient for Your Highness the Princess to return her to me? I

We are willing to give you adequate compensation."

Lin Xihan smiled sarcastically: "Do you think I am so easy to deceive?"

The girl's complexion and facial features were of Oriental origin, which had nothing to do with them. The truth was probably that they also discovered something extraordinary about this girl, so they rushed over to try to rob her.

"But, Your Highness..."

Pabol wanted to say something more, but the person in charge of the chamber of commerce next to him winked, and a group of expressionless guards came over and drove them away without explanation. This is the royal capital at the top of Kunlun, and a dignified princess does not need it.

Care about the feelings of these outsiders.

Qin Feng's eyes hidden under his sunglasses glanced at them coldly, wondering whether he should send someone to silence them, otherwise there would be endless trouble later.

The convoy returned to the princess's mansion smoothly without incident, which surprised him a bit.

"Take her to take a bath, change her clothes, and remember to guard her personally."

Qin Feng said to Lin Xihan solemnly: "This girl is a little special. I will explain it to you after I have communicated with her."

"OK."

Lin Xihan also realized that the matter was not simple and nodded in agreement.

He then sat in the secret room for half an hour when he saw the princess with an inexplicably complicated expression leading the girl in.

She had changed into a pure white girl's dress, and her appearance and body were completely different from when she first came back. There was a strange golden glow in her painted eyes, and her whole temperament had undergone earth-shaking changes. Even

Lin Xihan, who is famous for her beauty in the royal family, looks a bit overshadowed when standing next to her.

"You go out first. I'll come with you after I finish talking to her."

Qin Feng said warmly.

Lin Xihan agreed a little reluctantly, and gave him a slightly resentful look before going out.

"Do you have a name?"

he asked the girl.

"You can think of one for me."

"Then let's call him Qin Hang."

"Can."

"Why do you think of coming to me? You should know that this will put you at great risk."

Qin Feng asked. He had never thought that the incarnation of the will of the world would come to his door. Normally, he who is carrying a starship would have an undying relationship with such beings.

right.

Qin Hang sighed: "There is still a glimmer of hope to find you. If I don't find you... I might really be finished!"

"how do I say this?"

"Isn't it my origin that you want?"

Qin Hang said calmly: "I can give it to you. As long as your appetite is not too big, I should be able to satisfy you. As long as you can help me clean up all those disgusting things."

"I see."

Qin Feng instantly understood that as the saying goes, the enemy of the enemy is a friend, and it was impossible for him to let go of those aliens. As for the will of the world, or the will of the planet, these foreign aliens were also viruses that invaded her own body. If she

If it doesn't want to die, it must be obliterated at all costs.

"I have been secretly observing you for a long time."

Qin Hang explained: "Although you are protected by mysterious power, I cannot pinpoint your whereabouts, but the changes that have taken place in your territory, as well as the large number of meteorite fragments and alien species that have disappeared, can indirectly prove that my judgment is basically incorrect.

Something could go wrong."
