"Big brother!"

After Illya saw Tang En, she pounced without saying a word, and then raised her little face to stare at Tang En, and Tang En actually saw a resentful look in her eyes.

it!? She's just a child!

"Elijah, it's been hard work, I heard that with your help, the progress of the research institute is very fast?"

Before Elijah could speak, Pamela next to her smiled and said: "That's true, Elija's magical talent is incomparable, it's really hard to imagine that she is a little human girl, with her help, we have successfully copied the topological model of the magic array, but now there is a new problem." ”

Pamela doesn't know Illya's true identity.

Illya, who was robbed of words, pouted, and simply buried her head in Don's arms and stopped talking.

Don rubbed her hair and asked Pamela, "The magic circle has been copied, what's the problem?" ”

"The magic array stamping machine you provided."

Pamela paused for a moment, and said slowly: "I have to say that this idea of yours provides a convenient idea for the batch portrayal of the magic array, which is simply a genius-like idea, but now there is a problem, the volume of your improved miniature magic array is too small, and the printing accuracy of the magic array press cannot meet the processing requirements, we have tried many times, and the yield is very low, and nine times out of ten it will cause the magic power to overflow due to the instability of the magic channel, and then explode." ”

"Mana overflow?"

"Yes, because of the accuracy of the press and the substrate material that carries the magic circle, the stamped magic circle cannot reach the accuracy of your manual depiction. Due to the instability of the magic channel, after laying the magic dust, we observed the formation of magic turbulence in the magic channel, and after activating the magic array, the magic turbulence caused the instability of the magic array......"

Pamela's voice has the rhythm of Elven language, which is very pleasant to sound, and although the speed of her speech is slow, it clearly expresses her meaning to Don.

"In the end, is it still a question of machining accuracy?"

Don frowned slightly, Plantal's industrial base is very poor, and of course the micro-engraving technology can't be expected, not to mention that compared with the CPU immersive photo-engraving technology on the earth, which is often a few nanometers on the earth, it is difficult to achieve millimeter-level finishing.

And the magic array stamping machine that Tang En designed and built at the beginning was only made to adapt to the production of magic energy furniture, and those magic energy furniture were very large in size, so there was no problem in this regard.

And now, the advent of the magic pistol has magnified this problem.

"Yes, despite our efforts to try everything, we still can't solve the problem of overflowing mana."

Pamela was also very troubled by this problem, as an elven scholar, of course she knew that the miniaturization of magic arrays was very difficult, but why was it difficult after miniaturization? She also only knew that miniaturization would cause instability in the magic channel, and as for why it was unstable, she couldn't say one, two, three.

This is true even for elves, let alone humans.

The problem now before Don is clear, if the precision of industrial processing cannot be further improved, the mass production of magic pistols will be a flash in the pan.

Of course, Don can process the magic circle into its original form, and then use Transfiguration to shrink it, and then make it constant—but how efficient can he be alone?

Therefore, machining accuracy is a key technology that must be solved!

However, the problem of machining accuracy involves a lot of things, whether it is microscopic observation technology, or the accuracy of the mold and the material of the substrate, etc., all of which need to be solved step by step, and many of the problems involved in this cannot be done in one step.

For example, when it comes to the mother machine of the magic array stamping machine, Tang En can actually use alchemy to manually build a stamping machine with higher processing accuracy, but they have no observation technology and cannot further improve their industrial processing skills, and they will still be blind when they encounter this kind of problem in the future.

So what needs to be solved now is actually to improve the observation scale of Plandal, to improve the observation technology of centimeters and millimeters to the micron level, and after understanding the microscopic world, they will naturally notice the problem and the technical direction that needs to be improved, and then they will naturally point out the corresponding technology tree.

Don doesn't know much about the specific technology of the microscope, but he only knows a rough idea, he is just an ordinary college graduate with a wide range of knowledge, and he has been graduating for many years, and it is already very good to be able to recall some of the principles.

On Earth, a thousand-fold light microscope was invented in the eighteenth century, allowing people to see the shape, size and internal structure of microorganisms with their eyes.

It was not until physicists discovered the law between magnification and resolution that people knew that there was a limit to the resolution of optical microscopes, and this limit of resolution limited the infinite increase in magnification, and 1600 times became the highest limit of magnification of optical microscopes, which made the application of morphology in many fields very limited.

Although the optical microscope is not as good as the electron microscope, don't think about the electron microscope, if he had that kind of knowledge reserve, it is estimated that he would have gone to heaven long ago.

The discovery of microscopy has helped people understand the microscopic world, greatly broadened the development process of biology, physics and materials science, and every improvement in the scale of observation will bring about a rapid development in science and technology, which shows the importance of observation technology.

At the moment, Don hadn't heard of Brandal's microscope-like magic, and the effect of the gifted Eagle Eye was that of a telescope, and the corresponding optical phenomena and principles were completely unnoticed here, so now he was going to be a magic stick again.

Looking at the busy personnel in the research institute, Pamela with a troubled face, Don pondered for a moment, and then he said, "I don't know if you have heard of the principle of lens?" ”

"Lens principle?"

Pamela looked dazed, she turned her head to Nokia and shouted, "Master Nokia, have you heard of the principle of lenses?" ”

"Don't call me Master! I don't deserve the title of master...... How does the lens work? I seem to have heard similar words somewhere. ”

Nokia put down his work, frowned, and walked over and said, "I can't remember where I've seen this word before, it seems to be recorded in a document excavated in some ruins." ”

Don smiled slightly, the gnomes must have pointed out this technology in the past, otherwise they would not have been able to make a nuclear bomb to land on Plantal's satellite.

"The principle of the lens is very simple, have you ever noticed soap bubbles?"

"Soap bubbles?"

A group of people shook their heads, soap was still made by Donn, and it has only recently been popularized as a daily product, and people only pay attention to the convenience of soap, where to pay attention to soap bubbles.

"Uh, okay, let's change the example."

Tang En thought for a moment, put down Eliya, and then snapped his fingers, and the water element in the air beside him quickly condensed, forming a convex lens with a thick center and thin sides according to his consciousness.

Then he came to the yard with a group of curious babies, and after taking a look at the Ambica (sun) in the sky, he asked Nokia to fetch some hay and put it on the ground, and then pointed to the convex lens floating next to him and said, "This is a typical convex lens, and its function is to gather light beams." ”

"Gathering beams?"

A group of people are confused again, light is light, can they still gather?

Don was not busy explaining, and after they finished reading the experiment, they naturally understood.

He adjusted the position of the lens so that the focus fell on the hay, and said, "Look. ”

A group of people stared at the hay, and then were surprised to find that a very bright point of light suddenly appeared on the hay.

"That point of light is the beam that is gathered, and it's very hot, but it's only at the focal point of the lens."

Due to the large volume of the ice lens he pinched, the refractive index was very strong, and the hay had already begun to smoke when Tang En spoke, and as soon as the words fell, the hay had already made a soft "bang" and burned.

"It's on fire!?"

A group of people were taken aback, obviously they didn't see the lord use a spell, but just used a strange "lens", and the hay was actually ignited?

"That's right, as I said, at the focal point of the lens, all the light passing through the lens is refracted at one point, so the temperature there is very high, and it can be used for ignition."

Tang En patiently explained, then he lowered the lens, smiled slightly, and said, "But that was the principle of another field just now, and now I let you see it...... After the lens, you can come and take a look. ”

Pamela stepped forward, looked down through the lens, and then she froze.

"What's wrong, what's wrong? I'm going to see it too! ”

Nokia, who was most interested in the new stuff, jumped and shouted, "You guys are discriminating against the height of the dwarf!" ”

Don laughed dumbly, and as soon as his mind moved, Nokia's feet rolled in the dirt and lifted him up, Nokia couldn't wait to look over, and then suddenly let out a scream: "Oh my God! This, this, is this the principle of the 'Master Engineer's Glasses' recorded in the literature!? It's so easy!? ”

Tang En was stunned: "Master Engineering Glasses? Do you have dwarf X-ray glasses? ”

"Yes! No! ”

An excited Nokia danced and shouted, "In one of the ruins we have excavated, a surviving document records that in the past civilization, one of the necessary aids for a true engineer is a tool that can be worn on the eye, which can help master engineers to carry out precise machining work - but we have not found a single prototype for reference!" It's still a tough problem to solve! ”

Nokia said excitedly: "I can't imagine that the principle is so simple!" Ray! Lens! That's the secret! ”

Don breathed a sigh of relief, it would be good to have a race that understood science, otherwise he would probably have to struggle to explain the detailed principles, which would be even more troublesome.

"That's right, that's right."

Donn nodded: "In addition to convex lenses, there are also concave lenses, single-sided convex lenses, and so on...... And most importantly, if you put these together...... You will discover a whole new world. (To be continued.) )
