Hearing the explanation of the Osto people, the Earth City scientists who came forward to inspect touched the side of the oxygen generator, and their eyes lit up.

After he stood up, he quietly stepped back, came to Dai Funi and Jia Yan, and said softly.

"My lord, he admitted that he was wrong, although this manufacturing machine was indeed leaked by the military. But it's not the Osto people or the Ronglan clan, it's the Biochemical Empire, and the model is indeed the latest! The Biochemical Empire's stuff, known for its durable leather, can be retrofitted to the Devile transport ship and used in conjunction with the original oxygen production system, greatly increasing the oxygen production capacity of the transport ship. ”

Devoni's eyes lit up for a moment.

It seems that these second-hand dealers' things are really likely to appear boutique?!

"Oh no, no, no! How can you offer this price? You must know that I am a regular store with after-sales warranty, and it is definitely not their kind of store that opens today and runs away tomorrow, what? You say you can repair it? No, no, you can't sell it at that price. ”

"Sell it to him, they are honored guests."

When the one-armed Osto man wanted to raise the price loudly, a voice behind him made him stop talking.

"No, no, no, this is Ao Wuge's shop, and others can't help Ao Wuge make decisions...... Forehead! The one-armed Ostor looked back as he began to argue.

Although the price of this thing he purchased himself was not too high, how could he let go of the opportunity to make a lot of money when he saw some sellers who might pay a lot of money? So at this time, he was extremely angry with the guy who spoke!

But his words soon stalled.

Jia Yan and the others also looked at the huge body that was coming in front of them.

I saw a monster that was almost more than twenty meters away. This monster has six legs. Strangely enough, there was a crystal-like thing growing on his head. It's weird.

"It turned out to be Lord Jingraf! Are they friends with adults, okay, Brother Ao will give them the lowest price. When the Osto man saw the monster, he quickly smiled flatteringly.

He quickly settled the money for Jia Yan and the others, and the lowest price was impossible, but he traded according to the price proposed by the technicians of the Earth City.

"This is the leader of the Devella settlement, be careful, it looks like they already know who we are." Dai Funi leaned over to Jia Yan's side with a solemn face. Explained softly.

"Don't be so nervous, if I'm not mistaken, this is the Assassin who can fight one of the five powerhouses of Osto, the spear god Okudomu, right? With you here, my small settlement doesn't dare to do anything bad to you, and this is not in line with the neutral practices of our settlements, so don't worry. The six-legged monster opened its mouth and bared its fangs, as if smiling.

"The contemptible is indeed the leader of this settlement, and you can call me Realmraf."

"So it's Lord Naraff? I don't know if Lord Ralph came here this time, what do you have to ask?! ”

Jia Yan was silent for a while. Then it's time to take a step forward!

His body reached a length of thirty meters, plus the bearing of a powerhouse that reached the level of a starry sky. In an instant, the momentum of the realm Raf that faintly surpassed the other powerhouses in Earth City was suppressed without a trace of surprise!

Jing Raf was moved, and it seemed that the meaning of jealousy was also much more abundant. Still, he smiled professionally.

"Lord Assassin, I came to see you this time to facilitate a deal, and from your actions, I have judged that your ship is probably in need of a major modification before it arrives in my settlement, right? I'm the person who likes business the most, why don't we see if we can make a business? After all, if I go all out to find supplies, I guess it won't be a problem to satisfy you!"

"Oh?!" Jia Yan was stunned for a moment, and then said, "What do you want to trade?" Money? Or is it a trade in materiel?! ”

"What I want is not money, that thing is too empty, I want a spaceship, although your power may also be in short supply of spaceships, but I only want one or two of them, if you can exchange two small spaceships for the modification of the entire fleet, you are also willing, my lord?" It's a good deal. ”

Jingraf stretched out his slender tongue and licked it lightly at the corner of his mouth, obviously this guy is extremely fond of doing business.

"Good! I'm willing to trade! It didn't take long for Jia Yan to agree.

Naturally, there were more professional people who discussed the list of transactions with Gilaf.

Devoni is also involved, because only she knows that Earth City wants more than just a mod! If the entire fleet wants to sail to the solar system, the supplies needed will be astronomical, and Devoni is here to see if she can get what she needs.

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

Zaraf obviously doesn't want to sell too much energy either, so it's going to be a long negotiation and dispute.

Jia Yan saw that he didn't seem to be able to help much, so he simply walked out of the negotiation mansion that Jinglaf had arranged for them to enter, and strolled around this settlement city.

Powerful lifeforms are generally very huge, Jia Yan can basically only walk on the main street, and compared to almost all monsters, his body is a little larger, which also means that his strength is also superb!

Along the way, although there were that kind of ill-intentioned eyes everywhere, after lingering on Jia Yan's strong and powerful body, they all hurriedly didn't dare to look at it again!

"Huh? Where is the library? There are still such institutions in this settlement. ”

From a distance, Jia Yan saw a huge building, marked as a library in several languages such as Osto.

Regarding his knowledge reserves, Jia Yan has felt that he is a little lacking through some recent things. I didn't pay attention to these things before, but now I can find a way to add them.

So he paced slowly.

This is the official so-called library of the settlement, but this is also the approximate meaning of Jia Yan literally translated into the earth through the Osto language. This library is a library that doesn't own paper. Instead, intelligent brains of different sizes are built here. If you buy a certain book, you can pay to download it to your brain!

Jia Yan also has a smart brain, 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 more than half of the interior space by himself!

"This ...... This lord ...... Alas! Several administrators of the library saw Jia Yan stomp on the ground a little with one foot, and they stopped talking.

You must know that the current big mosquitoes may be the largest in this settlement, and they are not easy to provoke just by looking at their appearance. After all, such a huge body is at least heaven-level, or even heaven-level peak, and it is the top powerhouse of the settlement. They can't afford to provoke them!

After Jia Yan looked at the rules of the library for a while, he stopped in front of the largest brain. However, this is still a little small for him, carefully controlling his brain with brainwave power, piercing into a slot of the large brain brain, a huge holographic screen of more than ten meters suddenly appeared in front of him!

Jia Yan stretched out his forefoot and touched the screen frame, only to see that the virtual screen followed his touch. Instantly change shape, height, etc.

After adjusting to the optimal angle, he began to view.

"This is about some basic theory and basic technology of the process of civilization! Although it is useless for me. For basically all interstellar civilizations, they are also outdated things, but they still can't be found on regular planets such as gray and yellow stars, because this is the secret of advanced civilizations! Good stuff, definitely useful for the planet! ”

Jia Yan first discovered some advanced civilization technology, as well as social research and other materials, and his eyes suddenly lit up!

If Dai Funi and the others come to get these materials, it will definitely be easier to find more than Jia Yan, but places like Dai Weier's settlement may not come in the future, and only this kind of half-black and half-white force can find more in-depth information, and Jia Yan naturally can't miss it.

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

Due to the increase in strength, Jia Yan's thinking and movements were not something that ordinary creatures could catch up with, and at this time he concentrated a little, so browsing became extremely fast.

The holographic screen is shielded by the angle of view, and it is difficult for the outside world to detect what he is looking at.

"A systematic book of brainwave power! Good stuff. "Jia Yan has found useful information again, this time it is a brainwave force system book!

Although his brainwave power has already entered the room, it may even be more powerful than some starry sky level powerhouses, but after all, it has not been systematically studied, and these things may not have much effect on him now, but Jia Yan still bought them, and he can at least study them in the future.

He even had an idea!

That is, after returning to the earth, this material and scientific and technological information will be handed over to the earthlings together! If earthlings can also emerge with strong brainwave power, even if the process of becoming stronger may be extremely long, it is still a good direction for progress!

And what is the brainwave talent of earthlings, God knows? If you don't know that the talent is extremely strong, it is not necessary that some earth-level or even heaven-level powerhouses will appear soon!

Of course, this is just Jia Yan's delusion, he won't take this extravagant hope seriously, after all, in those interstellar civilizations, the talent of brainwave power is not so easy to obtain.

"Books about Evolution Beasts! It's still a forbidden book! Suddenly, after Jia Yan browsed the article about the Evolution Beast, his eyes lit up suddenly!

Don't hesitate to buy!

After that, he intermittently moved his forefoot, the huge holographic screen was really good, Jia Yan didn't fiddle with his brain before, just because the holographic screen was too small, he was uncomfortable to operate, and now this piece is huge enough, so that he has a lot of fun.

Soon, Big Mosquito's shopping cart was full of all-encompassing books, probably most of which belonged to the basics, and even some travelogues and novels - even because of cultural relations, Big Mosquito didn't understand these novels.

He bought so much, involving all aspects.

"Ten thousand osto dollars? ......" When checking out, Jia Yan was stunned.

"Yes, sir. Because many of the books you buy are forbidden to spread on a large scale in interstellar civilizations. For example, this ...... On nuclear energy further. And this one. How the basic star industry developed. and this ......"

The library staff was busy explaining to Jia Yan one by one. It's these books that are expensive. After all, some books are indeed forbidden books, although they dare to sell them here, they don't dare to blatantly sell them at ultra-low prices, after all, they really spread like that, and they are bought by many small primary civilizations, which is definitely not allowed by those advanced civilizations!

And if they sell it at a high price, low-level civilizations can't afford to smash pots and sell iron, don't look at Jia Yan, the funds they have can easily pay the price. But this is the gold and silver brought by the big mosquito with its extraordinary combat power, and it is difficult for ordinary primary civilization to even enter the starry sky, let alone have so many funds!

Of course, these books are said to be forbidden, but they are not extremely important things, and it is impossible for this settlement to have really important books.

"Send a message to your leader, Uraf, that I am an Assassin. Let's see if he's willing to give me a discount. "Jia Yan is not willing to pay such a large amount of money for these virtual books, and believes that he is trading with Earth City. I'll be willing to give a discount.

"Yes, sir!"

Hearing that this was a strong man, and he actually had something to do with the top leader of the settlement, those staff members suddenly became even more respectful!

"My lord, Lord Jinglaf said, these small things will be given as a gift for trading, if you still need it, other books will be counted as 50% off for you!" It didn't take long for the staff member to run back respectfully again.

"No need." Jia Yan shook his head, it seems that this realm is still very good at doing things.

He paced out of the library, and behind him were deep footprints that made the staff want to cry without tears.

"My lord! The deal has been basically finalized, in exchange for two 150-meter-class spaceships, plus most of the useless materials, for basically complete modification materials, and about eighty percent of the energy required for long-distance flights. This has exceeded my expectations, I wonder what adults think?! ”

Devoni's voice came out through the communicator.

"Tell me more about it." Jia Yan said quietly.

……

Five hours later.

Two unpleasant-looking spaceships shot out into the sky!

Not long after they flew away, some cargo ships from the Devile Settlement began to be loaded urgently!

Piles of huge supplies, as if they don't need money, are frantically loaded into cargo ships.

"Hey, this guy has made another big deal! He's been able to close similar deals lately, which is really enviable. ”

Some of the faction trading ships flying in the Devella settlement looked at the trading ships of the realm with envy. Looking at the scene of shipments, they felt extremely envious.

However, this level of transaction is not very huge for them, and it may only be a decent transaction for Jinglaf!

It's just two spaceships, and compared to the cargo ships docked outside the settlement, it's not enough to see at all.

But for Earth City, these things are absolutely earth-shattering!

The supplies for their transformation of the spaceship are coming!

"My lord, this deal is so timely, our oxygen crisis and food crisis are coming, and now it can be said to solve our urgent needs. Even we used the materials we couldn't use in exchange for an extremely scarce interstellar nutrient solution manufacturing line, which is a rare control material in general transactions, and with his future population food problem, it can reduce the pressure. ”

For the success of this operation, even Devoni, who has never liked to laugh very much, was full of smiles, and the smile like a city made the dark space faintly brighter.

"You're doing a good job." Jia Yan also rarely praised the negotiators.

"Nope! This is all due to you, my lord, you must know that the realm of Raf has always praised you, and he has asked us more than once vaguely if he is willing to cause a little trouble to several major civilizations, and I guess he still wants to restore the glory of his parents and make the natives rule the gray and yellow star again. Devoni shook her head.

"No matter what he thinks, it doesn't matter to us in the future, this place will soon be a thing of the past for us!" Jia Yan sighed lightly, the problem of grievances and grievances is like this in the entire starry sky, he doesn't want to get involved too much.

"That's right! When this batch of supplies arrives, I originally estimated that it would take a month to build the gravitational wave equipment, but it will be compressed to about half a month! When the time comes, it will be the day we return to Earth! ”

Hearing Jia Yan's words, Devoni was also a little excited.

Half a month? ……

Jia Yan was stunned for a moment, and then looked deeply at the deep starry sky......

Earth, Dad, Mom, Little Sister.

I'll be back soon!!

"Welcome back, adults!"

The two dilapidated ships were extremely fast, and they came to a starry sky surrounded by nothing, and here, the ships with almost all power turned off were quietly docked here.

Seeing Jia Yan and the others returning, there were voices of surprise and expectation in these spaceships!

They didn't take advantage of the departure of the two adults to make trouble or defect!

The lives of the people in Earth City were almost taken care of at this time.

"We're back! A large number of supplies will be delivered soon. Tell everyone to be on standby, prepare for the exchange of supplies and hull modifications, and next, it is the moment of great change for our Earth City fleet! ”

Devoni let out a slightly joyful command.

Not long after, the two ships came to a standstill, and Big Mosquito and Devoni quickly entered the largest of the transports, Daviel.

And at this time, in the various hulls, the general mobilization has begun!

It didn't take long for the mobilization of the two supreme commanders to start the division of labor among the intelligent beings who could only rely on Earth City now!

Not far away, the first handover ship for the Devil Settlement has arrived......

(In the book, it only takes half a month to return to the earth~~) (To be continued.) )
