Before the Shoah, the world's space industry had grown to a stage of extreme scale.

At that time, there were large space bases and space smelting workshops in low-earth orbit, synchronous orbit, and the airspace near the moon, and 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 human beings, but most of these industrial bases flying in the sky were preserved, and the industrial technology level of human civilization did not regress significantly.

The various materials that Qin Feng saw in the exhibition area, their excellent properties, were basically in the imagination of scientists in the main world, and they didn't know how long it would take to become a reality.

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

Another important area of production and processing in space is alloys and specialty materials and products. The use of mishap gaps and vapor phase alloys under microgravity conditions will result in the formation of new alloy structures and properties. The solidification phenomenon that occurs in space can even improve many of the properties of the alloy system.

In space, it can also manufacture castings with excellent properties, ultra-thin films, high-purity materials, acid-resistant materials, and multi-performance materials (such as malleable tungsten). It is possible to obtain a metal material as porous as Styrofoam, which can be as hard as steel on Earth, but light enough to float on the water. This special steel is absolutely impossible to make on earth, because even if the molten steel is filled with gas, the gas will escape to the surface of the molten steel and transpire. Since the advent of communication satellites, optical fibers have caused one of the most far-reaching revolutions in the history of communications. However, the distance and quality of the signal propagation of optical fibers are greatly related to the purity of glass fibers. In the universe, high-quality optical fibers with extremely high purity can be manufactured.

The Russians used to produce semiconductor crystals in the space station, and they made a profit. In the 80s, the most work done by the space shuttle was to take ESA's space laboratory to the sky to produce protein crystals.

It is a well-established belief in the Overworld that the industrialization of space can revolutionize the important high-tech field of materials science. Materials science and technology are the foundation of all other applied technologies.

After consideration, Qin Feng decided to buy all the 100 tons of rhenium metal. Other types 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 relatively inferior to that of talents and equipment, so Lin Xihan only entered the price and purchase intention on the light screen, and no longer let the person in charge of the Chamber of Commerce openly bid for the price.

When he came to the innermost exhibition area, he found it empty, a thin and unattractive little girl sitting cross-legged on the ground, closing her eyes and contemplating.

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

He half-crouched down, his ability quietly activated, staring at the girl carefully for a while, and his expression slowly became solemn.

"Your Highness, you ......"

Lin Xihan next to him was a little puzzled, could it be that Qin Feng likes this type? But this girl is dressed in ordinary clothes, looks and has an average figure, and she can't see the potential of an evolutionary, and she can't compare with the previous beautiful and radiant women, I really don't understand how she appeared 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 a 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: "Yes." ”

Lin Xihan's eyes widened, the price of the most outstanding female slaves on the scene is only 10 million, and this girl will ask for one billion when she opens her mouth? Who do you think you are?

"What's going on?" She asked disapprovingly.

The person in charge of the Chamber of Commerce hurriedly explained: "Your Highness, this is the case, this girl was inadvertently picked up from the wilderness by me more than half a year ago, and she did me a favor at that time, and then asked me to send her to ...... Send it to the southeast of the continent. ”

Qin Feng's expression moved slightly, that was her own territory, could it be that she was here for herself?

It seems to make sense, but she was still in the Overworld at the time, and the avatar was sleeping at that time, so she didn't find anyone. After returning, she didn't stay long before leading the army to fight the rot-clawed lizardmen, and she was unlikely to have a chance to come to her.

The words of the person in charge of the Chamber of Commerce confirmed his inference: "She seems to want to meet someone, but she doesn't say who it is, and then she went back to the royal capital with me, and said that sooner or later she will meet the person she is looking for, and then I can get a billion in payment?" ”

Lin Xihan sneered slightly: "I remember that you have always been very shrewd, you actually believe this kind of unreliable nonsense?" It seems that it was really a mistake for my father to let you take charge of the errand of the Chamber of Commerce. ”

"Your Highness, it's not like this, I ......"

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

"Forget it, a billion is a billion,"

Qin Feng glanced at Lin Xihan: "Transfer the money to him, and we'll 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 spiritual power, otherwise he would not have agreed to such an almost absurd request.

"Okay, okay."

Lin Xihan was full of doubts, but still agreed. She didn't want to upset Qin Feng, and she didn't pay for it herself anyway.

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

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

"Of course not."

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

Lin Xihan was confused when he heard it, but it was not easy to ask too much in front of everyone, so he could only wait until he went back.

When the group came to the exit of the venue, someone shouted loudly: "Wait! ”

Immediately afterwards, a large group of people rushed over, led by the two blonde and blue-eyed white Westerners, blocking Qin Feng and Lin Xihan's way.

"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 venue on the top floor, so they had been guarding the door, apparently having been waiting for a long time.

"That's ......"

One of the fellows saluted and hurriedly said, "In Lower Pabor, this little girl is the daughter of an old friend I have been looking for, and I would like to ask Her Highness the Princess to give her back to me?" I am willing to give you enough compensation price. ”

Lin Xihan smiled mockingly: "Do you think this palace is so easy to deceive?" ”

This girl looks at the skin color and facial features of the Oriental race, and has nothing to do with them, the truth is that they also discovered the extraordinaryness of this girl, so they rushed over and tried to snatch it.

"But, Your Highness......"

Pabol wanted to say something more, but the head of the Chamber of Commerce next to him made a look, and a team of expressionless guards walked over and drove them away. This is the royal capital at the top of Kunlun, and the princess doesn't need to care about the feelings of these outsiders.

Qin Feng's eyes, hidden under his sunglasses, glanced at them coldly, wondering whether to send someone to kill them, otherwise there would definitely be endless troubles behind.

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

"You take her to take a shower, change her clothes, and remember to watch over herself."

Qin Feng said to Lin Xihan with a solemn expression: "This girl is a little special, I will explain it to you when I have communicated with her." ”

"Okay."

Lin Xihan also realized that things were 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 has changed into a pure white girl's skirt like snow, her appearance and posture are completely different from when she first came back, and there is a strange golden glow in her painted eyes, and the whole person's temperament has undergone earth-shaking changes. Even Lin Xihan, who is famous for her beauty, stood with her, and she was a little overshadowed.

"You go out first, I'll come to accompany you when I'm done with her."

Qin Feng said gently.

Lin Xihan agreed a little reluctantly, and glanced at him with a slight resentment before going out.

"Do you have a name?"

He asked the girl.

"You can give me one."

"Then let's call it Qin Yan."

"Yes."

"Why did you think of coming to me? You should know that this puts you at a great risk. ”

Qin Feng asked, he really didn't think that the incarnation of the will of the world would actually come to the door one day. Normally, the self with a starship should have an endless relationship with this kind of existence.

Qin Mian sighed: "There is still a glimmer of hope for you." Not looking for you...... I'm probably really done! ”

"What do you mean by that?"

"Isn't what you want from my origin?"

Qin Mian 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 get rid of all that disgusting stuff. ”

"I see."

Qin Feng instantly understood that the so-called enemy of the enemy was his friend, and it was impossible for him to let go of those alien races. And for the will of the world, or the will of the planet, these alien aliens are also viruses that invade her own organism, and if she does not want to die, she must be erased at all costs.

"I've been secretly watching you for a long time."

Qin Mian explained: "Although you are protected by mysterious power, I can't lock your whereabouts, but the changes that have occurred in your territory, as well as the large number of missing meteorite fragments and aliens, can indirectly prove that my judgment is basically impossible to be wrong." ”

"If you're just like that group of aliens, just to devour and plunder, then you don't need to bother building a territory at all, and you can bring so many resources over. So I think we should have the possibility of sitting down and working together. ”
