In the end, Wang Chen used two tons of special engine oil to offset 2,000 trading points, plus 4,000 trading points in cash in exchange for the drawings of these two technologies.

After seeing the special engine oil provided by Wang Chen, the opposite side did not insist on the bottom line of his 7,000 trading points, and finally agreed to Wang Chen's offer of 6,000 trading points after bargaining.

"I said that you are also a seventh-order merchant, and you and I are here to buckle the rope at these thousand eight hundred transaction points. Beta 257 said with some dissatisfaction as he held a bowl of pale yellow liquid.

What he has in his hand is the bath water of the Salted Fish that has just been transported, Wang Chen doesn't feel anything anyway, but Beta 257 is full of praise, saying that this means that it is very good, not to mention that the fragrance is mellow, and it can also improve the internal operation efficiency of his body.

"Every businessman's belongings are accumulated in this little bit, and I am not a philanthropist. Wang Chen looked at this guy and seemed to like it very much, and wondered whether to produce another batch of engine oil and sell it.

It's just that the beta 257 on the opposite side seemed to see through Wang Chen's thoughts, and said with a smile: "Don't think too much, these two thousand transaction points are my private money, and now the money of the entire civilization has to be invested in the restoration of the home planet, and ordinary residents have no money to buy these high-end goods." ”

Wang Chen was a little skeptical, but in any case, he could be regarded as having successfully obtained these two technologies, although he still wanted another energy storage technology, but unfortunately Wang Chen's trading points were less than three hundred, and the price of that technology was five thousand three hundred points...

Moreover, the seller of this technology is the boss of this civilization, that is, the intelligent life, which is considered Guo Jia's property, and Beta 257 only has the right to sell and not the right to set prices, so Wang Chen can only take a look at it.

"Alright, everything is already here, I should go back too, I'll see you again. Wang Chen put away a disc with two pieces of information and planned to leave.

Beta 257 didn't mean to keep Wang Chen, and waved his hand to let Wang Chen do it himself.

After confirming that the last batch of engine oil had arrived at the warehouse behind the other party, Wang Chen no longer lingered and left the shop that broke his heart.

Damn, just this one in and one out of the wallet directly broken.

The so-called money is cowardly, Wang Chen, who has no money, is not in the mood to go shopping, and he returned to his spaceship after strolling, and the consignment of goods has already been handed over, Wang Chen plans to sleep and leave tomorrow.

At this time, the scenery outside the window gradually dimmed, and the two purple-red moons in the sky, which were about the same size, emitted a somewhat strange light, which were the moons of this planet.

Wang Chen was sitting in the command chair eating the instant noodles in his hand at this time, and Xiao Cannon Fei Prald also made himself something similar to a vegetable salad.

Fortunately, this guy can barely eat the food stored by Wang Chen, otherwise he can only let Ergouzi synthesize the relevant nutritious toothpaste through the equipment of the folding space, that taste Wang Chen has tasted, and it is an insult to say that it is unpalatable.

"Anyway, is the technology of nuclear fusion so worthless? It's so easy to trade. ”

"Damn, I changed two technologies with what I drank, which is equivalent to using Moutai to exchange for a few foreign lithography machines. ”

"Maybe that's the gap, and we've struggled to tweak the technology for it, and we can swap it for drinks elsewhere. ”

I don't like to hear this, energy can benefit human beings materially, and wine can also satisfy human beings spiritually, and I think it's normal to be able to exchange with each other. ”

"Hehe, it's Maozi upstairs?"

"And mentally... I haven't heard Lu Xun say that it's even more sad to use wine to kill your sorrows, can you satisfy me and show me?"

"I'm more curious about the neuronal learning device that Lao Salted Fish bought, which sounds very lofty. ”

Wang Chen, who was watching the barrage of food, stretched out his hand to wipe his mouth, put the exhausted instant noodle bucket on the narrator's table, and saw that everyone was discussing this matter, his eyes rolled and explained with a smile

"It's not surprising that the technology of the first, second, and third stage civilizations is the cheapest, and once it enters the fourth-order civilization, the price of the technology it sells will skyrocket.

The reason for this is also very simple, due to the continuous development of cosmic trade and the continuous integration of various civilizations, the promotion of civilization in the first, second and third stages is the simplest, so it is also called the bottom civilization.

In the era of the explosion of science and technology, many bought technologies can only play a reference role, and their purpose is to provide nutrients for the technology trees of the local civilization.

So as long as it is a conventional technology, it is basically not too expensive, as I said before, whether it is expensive or not is the second, the most important thing is to see whether it is suitable.

Fertilizer should also be taught according to aptitude, it can improve the development of the civilization of the science and technology tree, and naturally it is possible to raise death or raise crooked, so how to ensure that their technology tree is not led astray is the first thing that the bottom civilization needs to consider.

And once it reaches the fourth order, after entering the mid-end civilization, its own technology tree has grown, the elimination cycle of many technologies has been extended, and the perfection has been improved a lot, especially the crystallization that integrates its own local technology tree after the initial growth is not so cheap.

To take the simplest example, the engines used in the warships of the fourth-order civilization generally do not sell the technology to you, but directly sell the finished product for sale, while the bottom-end civilization generally sells the drawings directly instead of the finished product because there are flaws in it, but because the elimination speed is too fast, there is no interest in improving it.

Or the same gene enhancement technology, the fifth-order civilization may sell for millions of trading points, and the bottom-end civilization only needs one or two thousand or a few thousand, and even so, no one dares to buy it, because no one dares to use it at all, and these technologies are more to buy back to provide an idea for local scientific research.

Only in the mid-range civilization can it raise the price after it has developed its own technological style.

Therefore, the technology trade of the bottom civilization is not profitable at all, but the money is made by the trading of raw materials, minerals or large quantities of weapons, etc., which are the most profitable.

As for what I want this neuronal learning device for... It's very simple, learning is the first driving force for the development of science and technology, I think your study time is not enough, but people's energy is limited, it is impossible not to sleep.

Therefore, I plan to use this technique when you are sleeping, so that you can still study while you are asleep, for example, the majority of college entrance examination students can continue to have a set of Huanggang secret papers while sleeping, or the five-year college entrance examination and so on.

Isn't it perfect? Happy?

So don't thank me, I'm all for your good~Love you~Why!"

Wang Chen explained with a smile.

As soon as the audience heard this, a large number of barrages of condemnation immediately appeared.

"Climb for you!"

"Get out of here with your skills!"

"Thanks, we don't need this. ”

"??? grandma, I really thank you!"

"Are you the devil?"

"God sleeps and does the question, can you do something in the sun? ”

"It's a joke, it's a joke! It's going to die, hey!"

"Grass!

Seeing that the big guy seemed to be a little excited, Wang Chen smiled even more happily, just kidding, I saw that you were all excited.
