After hearing the explanation from the Ostos, the Earth City scientist who came forward to check touched the side of the oxygen generator, and his eyes lit up.

After he stood up, he retreated calmly and came to De Fu Ni and Jia Yan, and whispered softly.

"My lord, he acknowledged it wrong. Although this machine was indeed flown by the military. But it is not the Ostos or the Ronglan family, but the biochemical empire, and the model is indeed the latest! The thing of the biochemical empire, It is famous for being durable and skinny. If we buy it, we can add it to the Deviler transport vessel and use it with the original oxygen generation system, which will greatly increase the oxygen generation capacity of the transport vessel. "

De Fu Ni's eyes flashed for a moment.

It seems that these second-hand goods are really likely to appear fine? !!

"Oh no no no! How can you offer this price? You know I'm a regular store with after-sales warranty. It's definitely not the kind of store they opened today and tomorrow, what? You say you can repair it No, no, then the price cannot be sold. "

"Sell him, they are distinguished guests."

When the one-armed Osto loudly wanted to raise the price, a voice in the back made him stop.

"No, no, this is Owu's shop. Others can't help Owu to make a decision ... Uh!" The one-armed Ostrow looked back while arguing in his mouth.

Although he didn't buy the item at too high a price, but when he saw some sellers who might pay a large price, how could he miss the opportunity to make a fortune? So at this moment he was extremely angry at the guy who spoke!

But his words soon stagnated.

Jia Yan and others also looked at the huge body walking towards him.

I saw a monster that was more than twenty meters long. This monster had six legs. It was strange that a crystal-like thing was growing on his head, which was weird.

"It turned out to be King Raf! Are they adults' friends, okay, Owu will give them the lowest price." The Osto saw the monster and smiled flatteringly.

He quickly settled the money for Jia Yan and others. The lowest price was impossible, but the transaction was made at the price proposed by the technicians in that Earth City.

"This is the leader of the Devil's Settlement. Be careful, it seems that they already know our identity." Da Fu Ni leaned against Jia Yan solemnly and explained softly.

"You do n’t have to be so nervous. If I read correctly, this is one of the five strongest men who can fight against Ostor, Lord Assassin, Odowu, is n’t he? I dare you to live in this small settlement I care about you, and this is not in line with our usual neutrality in the settlement, rest assured. "The six-legged monster opened his fangs and seemed to be smiling.

"I'm really the leader of this settlement, you can call me Jingraf."

"It turned out to be King Raf? I wonder if King Raf came here this time. Any advice?"

Jia Yan was silent for a while, then took a step forward!

His body reaching 30 meters in length, plus the strength of a strong star who reached the level of the starry sky, instantly overwhelmed the power of Jing Raf's overwhelming power of other strong men in Earth City!

Jing Raf moved with a lot of dread. But he still smiled professionally.

"Master Assassin, I came to see you this time in order to facilitate a transaction. Based on your actions, I judged that your spaceship is estimated to require a large-scale modification before you arrive at my settlement? I like to do business the most. Now, let's see if we can make a business? After all, if I try my best to find supplies, it will not be a problem to satisfy you! "

"Oh ?!" Jia Yan froze for a moment before he said, "What do you want to trade? Money? Or materials ?!"

"What I want is not money. That thing is too vain. I want a spaceship. Although your power may be in short supply, I only want one or two of them. If I can exchange two small spacecrafts for the entire ship, Modification of the team, adults, would you also like it? This is a good deal. "

Jing Rafu stuck out his slender tongue and licked it at the corner of the mouth. Obviously, this guy is very fond of doing business.

"Okay! I'm willing to trade!" Jia Yan agreed without considering how long.

Next, there were naturally more professional people who had a checklist discussion of the deal with Hoa Raf.

Da Fu Ni is also involved, because only she knows that Earth City wants more than just modification! If the entire fleet wants to sail to the solar system, the materials needed will be an astronomical figure. Defferny is here to see if she can get what she needs.

Energy is something that every power is in short supply of, and for the current fleet size of Earth City, it is even more of a shortage!

Obviously Rav also didn't want to sell too much energy, so this would be a long negotiation and controversy.

Looking at himself, Jia Yan didn't seem to be of any help. He walked out of the negotiating mansion that Jing Raf had arranged for them to enter, and walked in the settlement city.

The powerful life form is generally very huge. Jia Yan can basically only walk on the main streets, and compared with almost all monsters, his body is a bit bigger, which also means that his strength is also incomparable!

Along the way, although there is that kind of unsightly sight everywhere, but after lingering on Jia Yan's strong and powerful body, they are afraid to look at it!

"Well? Where is the library? There are such institutions in this settlement."

Jia Yan saw a huge building from afar. It was marked as an institution like a library in several languages ​​such as Ostto.

Regarding his knowledge reserve, Jia Yan has felt that he is somewhat inadequate through some recent events. I didn't pay much attention to these things before, but now I can find ways to add them.

So he paced slowly.

This is an official so-called library officially established by the settlement, but this is also the approximate meaning of Jia Yan's literal translation into the earth through the Osto language. This library is a library that does not own paper, but a large-sized library. One's brain is built here. If you buy a book, you can download and download it to your brain!

Jia Yan also has a mental model, which is still a good model. It's just that I haven't had time to study and know the general operation.

He entered the tall building and immediately occupied most of the interior space alone!

"This ... this lord ... oh!" Several librarians saw Jia Yan break the ground a little with one foot, and stopped talking.

You must know that the current large mosquitoes may be the largest in this settlement. Just looking at the appearance shows that it is not a provoke. After all, such a large body is at least a sky-level, even a peak of a sky-level, but Top settlements. They can't provoke it at all!

After looking at the library rules a little, Jia Yan stopped in front of one of the biggest intellectual brains. However, this is still a bit small for him. He carefully controlled his brain with brainwave power and pierced a slot in the large brain. Suddenly a huge holographic screen full of ten meters appeared in front of him!

Jia Yan stretched out his forefoot and touched the screen border. I saw that the virtual screen immediately changed shape and height according to his touch.

After adjusting to the best angle, he began to watch.

"This is the basic theory and basic technology of some civilization processes! Although it is useless to me, it is also outdated for almost all interstellar civilizations, but it is still not found on regular planets such as gray and yellow stars, because this is advanced The secret of civilization! Good things, absolutely useful for the earth! "

Jia Yan first discovered some advanced civilized science and technology, as well as social studies, etc. His eyes suddenly turned on!

If they come to find these information, they can definitely find more than Jia Yan, but places like Devier Settlement may not come in the future, and only this kind of half-black and half-white force is possible. Finding in-depth information, Jia Yan is naturally impossible to miss.

Setting these to the shopping basket, Jia Yan continued to move his forefoot, and the picture scrolled on the holographic screen.

Due to the enhancement of his strength, Jia Yan's thinking and movements are not able to catch up with ordinary creatures. At this time, he is slightly focused, so browsing becomes extremely fast.

The holographic screen has a perspective shield, and it is difficult for the outside world to detect what he is looking at.

"System books on brain wave power! Good stuff." Jia Yan once again found useful information, this time with books on brain wave power system!

Although his brain wave power has already entered the room, he may even be more powerful than some star-level powerhouses, but after all, it has not been systematically studied. Maybe these things have little effect on him now, but Jia Yan still bought them, and at least can research them later.

He even has an idea!

That is, after returning to the earth, this material and scientific and technical materials will be handed over to the earth people! If the people of the earth can also emerge with strong brain wave power, even the process of becoming stronger may be extremely long, but it is still a good direction of progress!

And what is the brainwave talent of the earth people, God knows? If you don't have a strong talent, you will soon be able to see some prefecture-level or even natural-level powerhouses!

Of course, this is just Jia Yan's delusion. He won't take this extravagance seriously. After all, in those interstellar civilizations, the talent for brainwave power is not so easy to obtain.

"Books about evolutionary beasts! It is still forbidden | books!" Suddenly, after Jia Yan browsed the article about evolutionary beasts, his eyes flashed suddenly!

Don't hesitate to buy!

After that, he jogged intermittently on his forefoot. The huge holographic screen was really good. Jia Yan didn't fiddle with his own brain because the holographic screen was too small and he was not comfortable to operate. Now this piece is huge enough to make him Have fun.

Soon, the big mosquito's shopping cart is already full of sights, it can be described as all-encompassing, there are some books, and most of these belong to the basic knowledge, and even some travel notes and novels-even because of cultural relations, the big mosquitoes have no idea Don't understand.

He bought so much and it involved all aspects.

"One ten thousand Osto dollars? ..." Jia Yan froze at the checkout.

"Yes, sir. Because many of the books you buy are forbidden to spread on a large scale in interstellar civilization. For example, this ... on nuclear energy. And this one, how the basic starry sky industry developed. And this……"

The library staff was busy explaining Jia Yan's one book. The expensive ones are these books. After all, some books are indeed banned. Books, although they dare to sell here, they dare not sell them blatantly at super low prices. Spreading out and being bought by many small primary civilizations is definitely not allowed by those advanced civilizations!

And the high price sold, the low-level civilization ca n’t afford to sell iron. Do n’t look at the funds that Jia Yan can easily afford the price, but this is the gold and silver brought by the large mosquito that exceeds the conventional combat power. Civilization is difficult to even enter the starry sky, not to mention having so much money!

Of course, these books are said to be banned, but they are not very important. Really important books cannot be owned by this settlement.

"Give a newsletter to your leader, Love, and say that I am an assassin, and see if he is willing to give me a discount." Jia Yanke is unwilling to pay so much money for these virtual books. Would like to give a discount.

"Yes, sir!"

Hearing this is a strong person, has a relationship with the highest leaders of the settlements, and those staff members are even more respectful!

"Sir, Lord Jingraf said, these small things are treated as gifts for the transaction. If the adults still need them, you can get 50% off for other books!" It didn't take long before the staff member ran back respectfully again.

"No need." Jia Yan shook his head, and it seemed that Rav would still be good at it.

He paced out of the library, and behind them were the deep footprints that made the staff cry.

"My lord! The deal has been basically finalized. With two 150-meter spacecraft, plus most useless materials, in exchange for basically complete modified materials, and about 80% of the energy required for long-distance flights. This has exceeded my expectations. , I don't know what adults think ?! "

Daisy's voice was transmitted through the communicator.

"Tell me more about it," Jia Yan said calmly.

...

Five hours later.

Two seemingly unsuccessful spaceships shot out towards the sky!

It didn't take long for them to fly away, and one after another, there were some cargo ships in the Devier settlements, and emergency loading began!

A pile of huge supplies, like no money, were loaded into the cargo ship frantically.

"Hey, this guy Rav has completed another big deal! Recently he has always been able to complete similar deals, which is really enviable."

Some forces flying in the Devier settlement traded the spaceship, and looked at the trade spaceship in Jingrafu with envy. Looking at the shipment, they felt extremely envious.

However, this level of transaction is not too huge for them, and it may be just a fair deal for Jing Raf!

It's just two spaceships. Compared to the cargo spacecraft that docked outside the settlement, it's not enough.

But for Earth City, these things are absolutely amazing!

They are transforming the spacecraft's supplies, coming soon!

"My lord, this transaction is too timely. Our oxygen crisis and food crisis were coming soon. Now we can solve our urgent needs. We even used unused materials in exchange for an extremely scarce item in the interstellar space. The production line of nutrient solution is a rare and controlled material in general transactions. With his future food problems, he can reduce the pressure. "

Regarding the success of this operation, even De Fu Ni, who has not always liked to laugh, was full of smiles, with a smile that made the city dark and faint.

"You did a good job." Jia Yan also praised the negotiating members.

"No! It's all your credit to the adults. You must know that the rave has always praised you, and he has asked us more than once. He has no intention to cause a little trouble for several major civilizations. I guess he still Wanting to restore the glory of his parents, the indigenous people ruled the yellow star again. "Da Fu Ni shook her head.

"No matter what his thoughts are, it has nothing to do with us in the future. This will be a past tense for us right away!" Jia Yan sighed, the question of gratitude and resentment is the same throughout the sky. He Don't want to get involved too much.

"That's right! When this batch of materials was in place, I originally estimated that it would take a month to build a good gravitational wave device. It would be compressed to about half a month! By that time, it would be the day we return to Earth!"

After hearing Jia Yan's remarks, Dai Funi was also a little excited with a little excitement.

Half a month? ...

Jia Yan stayed, then looked deep into the deep starry sky ...

Earth, father, mother, little sister.

I will be back soon! !!

"Master, welcome back!"

The two dilapidated ships were extremely fast, and came to a starry area surrounded by nothing, and here, a ship with almost all power off was docked here.

Seeing Jia Yan's return, surprises and expectations came from these spaceships!

They did not make trouble or defection while the two adults were leaving!

The life of the earth city is almost at this time.

"We are back! There will be a lot of supplies coming soon. Order everyone to stand by and prepare for the exchange of supplies and hull modification. Next, we will have a big change in the Earth City fleet!

Defferny uttered a command of joy.

It didn't take long for the two spacecraft to stagnate, and the big mosquito and Daifunni quickly entered the largest Devier carrier.

At this time, the mobilization of the hulls has begun!

Not long after, with the mobilization of two top officials, a smart creature whose name can now only depend on the Earth City began a division of labor!

Not far away, the first transfer ship of the Devil's Settlement has arrived ...

(It only takes half a month to return to the earth in the book ~~)
