When Xin Yu heard Chen Linqiang's request for a demonstration of science, he had a hunch that he might have something big.

If it is the concept of science in the air-to-air category, Xin Yu may still be able to say two nonsense. However, he also knew that talking about science with a practitioner who had not embraced the concept of popular science could be confusing, no matter how precise the expression was. And the things included in science are not a little bit of a star, if you don't understand it in a broad way, and if you don't talk about it in detail, it will definitely not make people form a concept in the last few days, not to mention, with Chen Linqiang's "hobbies", just insert a sentence in a place you don't understand, let alone a few days, you can't stop it for a few months.

It's intuitive to do experiments, but it's still the same sentence, Chen Linqiang is too verbose, when the time comes, there will be a hundred thousand whys, what should I do? Only by taking out "technology products" may be able to divert his attention and lose his mind, so that Xin Yu's ears can be cleaned up for a while.

Of course, there is also a point in showing the real thing, to make this gourmand who has opened his eyes and seen the world feel that it is lofty, and ordinary things are meaningless. However, the high-quality goods such as the computer ...... Xin Yu couldn't take it out. Therefore, he still thinks that it is better to be realistic, and it should be no problem to choose one or two "advanced" things in the technical reserves of his personal laboratory, and fool the old natives of this scientific and technological desert.

When it comes to the end, the bigwigs in the astral world also think it's better to be realistic. After all, ants are still stealing life, and this thing is a joke when they meet a strong person, and whether they lose face or not does not prevent them from surviving, right? If you offend the Great Star Sorcerer, maybe it's not just a matter of life. Besides, even if they stubbornly put their lives in vain, perhaps in the eyes of others, they still don't know the times and stubbornly touch their stupid hats with eggs and stones, and it seems that they can't be regarded as the glory of life and death, right?

"I think...... If we strengthen the supervision of our own disciples, we should be able to put an end to the temptation of those crooked ways, right?"

Since someone tactfully proposed to lift the ban, those bigwigs can comfort themselves with an ostrich mentality, and they can deceive themselves into saying that this proposal was not made by them. Even if it is disgraced, it should be the person who proposed it first to disgrace, at least they have persevered for a moment than Fenghua Moduo, right?

In fact, the ban is not forbidden, and it has nothing to do with the Star Refining Sect, and the disciples of the Star Refining Sect generally do not participate in the battles in the astral world, because they only need to exchange for star stones by refining star treasures, so the needs of the disciples to improve their combat effectiveness are infinitely close to zero.

Because of this, Feng Hua Mo didn't care about his prestige in the astral world in the future. After all, they themselves don't rely on combat effectiveness to eat, and it seems reasonable to be soft, especially in the face of a strong enemy. Besides, Xingbao is a rigid demand for astromagicians, and if you dare not give your master a smile, you will be in a bad mood, and if you are in a bad mood, you will want to refine Xingbao for you.

"Yes, anyway, the star magicians of the Great Liang Kingdom already have two or three big cats and kittens, and it's time to let go of the blockade. ”

"Yes, I think that with the lesson of the last time, the younger generations can also become more rational. ”

"Yes, it's been so long, let's just assume that the ban doesn't exist. ”

"Yes, yes, the ban was only a stopgap measure. Didn't the old Jin Zhenmao seniors also say that we should keep pace with the times......"

“......”

Immediately followed the post...... Oh no, it's the echoing voices, which shows that the mentality of these bigwigs is still relatively "pragmatic", dignity and face, compared to life and prospects, everything is empty.

"The old ancestors are so similar, can they lift those 'heavenly rules'?" Chen Moru was probably played miserably by the bigwigs in the astral world, and asked with some concern while Xin Yu was going to get the props.

"Phew, it's still 'Tiantiao'. In the eyes of the old man, it is just a house wine for children to play. Just look at those elders, the current astral realm no longer has the backbone we had back then. Rest assured, they will face reality. Chen Linqiang was very disdainful, but, as if thinking of something, he said again, "However, the old man only expects them to acquiesce to the ban in name only, and it doesn't matter if he announces it or not." ”

"That is, the prestige of the old ancestor is earth-shattering. I think they'll be interested. Chen Moru nodded, staring at the old ancestor with disgusting eyes.

Although Chen Linqiang was a little arrogant, he was just humble and straight: "Hehe, two fists are hard to beat four hands, before crossing that hurdle, the old ancestor didn't dare to say that he could match the entire astral world." ”

"How is it possible, isn't the Old Ancestor a Great Star Sorcerer, and you are still worried about the siege at your level?" Chen Moru opened his mouth in surprise, could it be considered that the Old Ancestor was being humble?

Chen Linqiang was a little embarrassed by this junior, he was mistaken for a great star magician, he didn't take the initiative to clarify, and it was because of this misunderstanding that he could easily deter those messengers. I didn't think that Chen Moru would also misunderstand, but he was really embarrassed to say that he didn't have enough understanding to become enlightened, so he said vaguely: "There are many ants that can bite the elephant to death......

He is not a genuine Great Star Warlock, and it is naturally unclear whether the Great Star Warlock can really ignore the number of low-level Star Warlocks, and he has not reached that realm.

Fortunately, Xin Yu was afraid that this long-winded old ancestor would be in a hurry, so he hurried back and forth with the light skills of flying on the breeze grass, and rushed back at the moment when Chen Linqiang was embarrassed.

"Show the old man what science is. Seeing Xin Yu, Chen Linqiang immediately showed his strong curiosity for science with great interest, leaving aside Chen Moru, who was also eager to learn about astrology.

Xin Yu gently put the backpack behind him on the table in the middle of the room, and then said while taking things: "Ancestor, the kid is holding a few things made by using scientific principles, which is a small manifestation of scientific application, and compared to the huge science, it is just a drop in the ocean. ”

The first thing Xin Yu took out was a convex lens. The function of the convex lens is to naturally magnify the real thing into a virtual image. This in itself is nothing magical, perhaps Chen Linqiang has seen it before.

However, Xin Yu didn't just pick something and take it, but after some careful consideration. Since Chen Linqiang is an astrologist, he must be more interested in fighting and killing. Another function of the convex lens is to focus the light, and the primary school students in the previous life knew how to use the convex lens to point the textbook...... It seems that where to call will not be clicked?

This will be the third pole of the sun, Xin Yu demonstrated it directly at the door, and within a moment, a piece of rattan paper was ignited.

"Huh?" Sure enough, Chen Linqiang was still more interested. He had seen countless strange star treasures, and it seemed that they also had this effect, but he didn't expect that even a mere mortal technique could do it.

The old naughty boy was still a little playful, he directly grabbed the convex lens, and did not play with fire with the paper that Xin Yu used to demonstrate, and lit it directly against the wooden threshold. However, the old naughty boy is also not well-behaved, and he still can't stop his mouth when he plays: "This is science?"

"It's a kind of science, guess. Xin Yu is still mentally prepared for this, "This is the principle of using the refraction phenomenon of light through different media......"

Balabala is a big pass, Xin Yu is not unavoidable, he simply came to the Yellow River and surged endlessly, and he swore not to give up without pointing to the essence.

Fortunately, although the old naughty boy is old, his head is not rusty. Although Xin Yu, a lecturer, is unqualified, Chen Linqiang can also understand the principle of light propagation, and he also extends to the problem of sound propagation.

This is a good talk, and Chen Linqiang is fascinated when he hears it, well, Chen Moru is also drunk. Impatiently, the old urchin turned around and stared at the bag on the table again, as if looking at Doraemon's magical pocket: "What else?" ”

Xin Yu, a traveler, has not been busy in vain in the past five years, and if he only makes a glass mirror, he will be embarrassed to claim to be knowledgeable. There are a lot of good things, etc and so on (dengdēngdéngdēng), and the heart gives the next item a grand appearance accompaniment......

"It's a hand-cranked generator. Xin Yu proudly introduced. Regardless of whether this thing can shock Chen Linqiang, he first praised himself for being able to make such a technical thing.

Six years ago, he could only make weak electricity from lead-acid batteries, and now this hand-cranked generator is also a 20W starting generator, which is far more powerful than the battery back then. If it weren't for the fact that Chen Linqiang was a dignified old man, it seemed unreasonable to take the initiative to move to Xin Yu's humble house, and he could still see the post-modern wind turbine.

And the way of expressing electricity is even more incredible, which is Mr. Edison's patent. If you don't give praise, Taobao won't be happy.

Don't look at these two things as having little technological content, but being able to replicate generators and incandescent light bulbs in this backward world is not a matter of the knowledge and hands-on ability of the traveler, but a revolution involving material systems and processing technology. Drawing process of tungsten metal and copper, preparation of graphite carbon rod and insulating varnish, sealing technology of glass and ceramics, vacuum technology, and even processing technology of metal bearings.

Therefore, no scientific and technological achievement can be achieved overnight. Just these two little things made Xin Yu and the workshop of nearly 100 people grope for more than half a year.

Of course, although Chen Linqiang is curious about things that can shine for no reason, he is only curious, and he does not give a good review. Xin Yu thought about it and understood that just glowing was powerless.

So he calmly took out the graphite carbon rod from the package, and then connected it to the two poles of the power supply, demonstrating the phenomenon of electric sparks. Sure enough, the Astral Warlock is an out-and-out combat profession, and when Chen Linqiang saw the arc between the carbon rods, his two eyes also began to discharge.

This time, the good students asked more carefully, and the not-so-good teachers were even more talkative.

As a master, Chen Moru thought that he knew his apprentice. However, when he heard the inexplicable terms such as electron, current, and short circuit that kept popping out of Xin Yu's mouth, he felt a little that he seemed to be blinded, because this apprentice who seemed to have absorbed the memories of visitors from outside the world said that he had a feeling of "I understand every word you say, but I don't know what it means when you connect them together".

Chen Moru has not yet reached the level where he needs to find the "Tao", so he doesn't care what "science" can bring. He only wanted the Ancestor to grind off the ban on his Star Sea as soon as possible, or let the Star Sorcerer who had sealed him come to unseal him. In addition, he can refine his astrological skills and strive to get rid of the so-called "crooked and heretical", and there is nothing else to pursue at present.

Picking up the convex lens that the ancestor was tired of playing with, and automatically filtering out the noise of the popular science lecture, Chen Moru seemed to have discovered a novel world, and regardless of the ancestor on his side, he exclaimed in an exaggerated manner: "This is ......"

Xin Yu and Chen Linqiang both raised their heads dissatisfied, and then said in unison, "What's the matter?"

Chen Moru said with some embarrassment: "This convex ...... Mirror, how can you magnify?"

"If you don't learn and don't know how to do it, didn't Xiao Xinyu just say the principle of light propagation? This is science, understand waves~" Since both of them look gray-haired old men, Chen Linqiang really didn't take the ear grandson of this ear grandson who he had just known for a long time as a descendant, so when he spoke, he didn't have the kind of seriousness or pampering that taught the younger generation, but it was like laughing and ridiculing his friends.

"That...... I mean, can you make things bigger, so that you can visualize them more carefully. Chen Moru argued.

Xin Yu asked strangely, "How big do you want to zoom in?"

"It's better to be able to see the smallest details. Chen Moru didn't know how to express it.

"Is it to the point of seeing indivisible particles?" Just listening to this, he knew that Chen Linqiang's understanding of the composition of matter was not necessarily worse than that of a science monk, but the next sentence leaked his bottom, "Be realistic, that's impossible, even the subtle realm of thinking is impossible to perceive so subtle, because particles can be infinitely divided." ”

Xin Yu opened his mouth, originally wanting to say that he could do it, but when he thought that the light microscope really couldn't see atoms, he didn't show how erudite he was. Is he going to "invent" the scanning tunneling microscope? Even the electron microscope can't be.

However, Chen Moru, who was staring at Xin Yu, suddenly saw something from the expression that wanted to stop talking, so he immediately grabbed Xin Yu's arms and said, "You can do it, right? Isn't science omnipotent?"

Xin Yu's face immediately collapsed: "This is impossible, when the diameter of the particle is smaller than the wavelength of visible light, phenomena such as diffraction interference scattering will occur, and it is difficult for the optical microscope to distinguish even small molecules, let alone atoms...... Maybe the scanning tunneling microscope can't see quarks either. ”

In the end, he is not a master of language, and after a few casual rebuttals, he almost exposed his bottom line. At this time, not only Chen Moru, but also Chen Linqiang was surprised: "Science can really do it......? Sweeping...... Microscope, can you make it?"

Shaking his head resolutely, Xin Yu didn't want to make trouble for himself: "That's a system project, and one person can never complete it...... Well, maybe 10,000 years might be considered. ”

Even with such an obvious refusal, Liang Chen still didn't let him go, and he thought that 10,000 years was too long, so he just said every day: "If one person can't do it, then can't you find many people? Isn't there hundreds of people in your workshop? ”

Then these two people began to persuade, comfort, threaten, and induce one by one...... Anyway, hard and soft words are poured out one by one.

Xin Yu was annoyed by this fatigue bombardment: "Okay, please be realistic, do you know what it takes to scan the tunnel telescope? The type and purity of the material, as well as a whole set of knowledge system and production process, the tunnel needle tip required alone is at least the nanometer level, do you know what the concept of nano is? Even if you give me a million workers like that." ”

"Then what do you mean when you say that a person can't do it?" Chen Moru said a little unwillingly.

"Please...... I'm talking about the kind of high-level scientific and technological personnel, not the kind of illiterate people who can't even write. If you can find a million Ph.D. monks in science, I promise to build them for you in 50 years. Xin Yu is reasonable, and he seeks truth from facts and speaks with facts.

"What monk? Is it difficult to find an astrologist? I'm responsible for finding it for you, there is no one in this world, I'll go to other heavens to find it for you." Chen Linqiang packed the ticket and said.

"It's not an astrology, it's the kind of ...... Ordinary people with a deep scientific background will be fine, but if you've been to a world full of astromagicians, I don't think so. "To put it simply, it's unrealistic anyway, it's impossible to say that quantum mechanics and so on are so complicated.

Chen Moru's eyes lit up: "Isn't the science you are talking about something that ordinary people can learn? Let's find a million ordinary people, and you teach them yourself." ”

Xin Yu was about to cry: "I teach millions of illiterate people alone? And I want to teach a million doctors and monks? That is impossible, absolutely impossible, and it is impossible for 10,000 years." ”

"It's not that you don't want to teach, right?"

Well, it seems that you will not give up if you exaggerate without a bottom line, so Xin Yushi opened his mouth and said: "I can teach at most ten qualified doctors of science monks in thirty years, and then let them spread science." It took more than 100 years to popularize education and higher education, and with 50,000 students, there would probably be one million higher science monks. Another 100 years to improve and upgrade the world's manufacturing industry...... When all the hardware and software are satisfied, it will take a few more years...... No, it took decades to build a scanning tunneling microscope. Of course, this is only an investment of time, and if the money can't keep up, it may be extended by hundreds of years. And the funds are needed...... There are about a dozen trillion taels of gold that is enough. ”

Although he doesn't understand what co-ordination is, Chen Linqiang still sensitively found the loophole: "It won't take that long, right?"

"At least three hundred years. Xin Yu said affirmatively.

"Three hundred years? is not a long time, you can wait. Chen Moru is also very sure of authenticity.

Xin Yu collapsed: "But can I live for three hundred years?"

"Didn't you say that Qi refining is no worse than star art? If you can't live for three hundred years, what can you talk about Qi refining? Just learn star art from your teacher. Chen Moru will remember his master's identity.

Can Qi refining live for 300 years? Xin Yu is a little unsure, like Peng Zu, can he live for 800 years?

P.S.: I don't seem to be used to it, don't talk nonsense, just ask for support!!
