"Big brother!"

After seeing Tang En, Yiliya rushed up without saying a word, then raised her face and stared at Tang En, who actually saw a resentful look in her eyes.

Damn!?She is just a child!

"Yilia, thank you for your hard work. I heard that with your help, the research institute has made rapid progress?"

Before Yiliya could speak, Pamela next to her smiled and said, "That's true, Yiliya's magical talent is unparalleled. 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 circle, but now there is a new problem."

Pamela didn't know Iriya's true identity.

Iriya, who was snatched up, pursed her mouth and simply buried her head in Tang En's arms and stopped talking.

Tangen rubbed her hair and asked Pamela: "The magic circle has been copied, what else is there?"

“The magic circle stamping machine you provide.”

Pamir paused for a moment and said slowly: "I have to say that your idea provides a convenient way to describe the magic array in batches. It is simply a genius idea. But now there is a problem. The size of your improved miniature magic array is too small, and the printing accuracy of the magic array stamping machine does not meet the processing requirements. We tried it many times, and the yield rate is very low. Most of the time, it will cause magic power to overflow and explode due to the instability of the magic channel."

"Magic power overflows?"

"Yes, because of the accuracy of the stamping machine and the substrate material that carries the magic array, the stamped magic array cannot achieve the accuracy you manually portray. Due to the unstable magic channel, after laying the magic dust, we observed that magic turbulence formed in the magic channel. After activating the magic array, the magic turbulence caused the unstable magic array..."

Pamela's voice has a unique rhythm of the elves, which makes people sound very comfortable. Although her speech speed is slow, she clearly expresses her meaning to Don En.

"At the end of the day, is it still a question of processing accuracy?"

Tang En frowned slightly. Plandal's industrial foundation was very poor, and of course micro-engraving technology could not be expected. Not to mention that compared with the CPU immersive photo-engraving technology that is often several nanometers on the earth, it is difficult to achieve millimeter-level finishing.

The magic array stamping machine designed and built by Tang En was only made to adapt to the production of magic furniture. The magic furniture is very large in size, so there is no problem in this regard.

And now, the emergence of magic pistols has magnified this problem.

"Yes, although we have tried every solution very hard, we still cannot solve the problem of magic overflow."

Pamela is also very troubled by this problem. As an elf scholar, she certainly knows that miniaturization of magic arrays is very difficult, but why is it difficult to miniaturize after miniaturization? She only knows that miniaturization will cause instability of the magic channel. As for why it is unstable, she can't say a little.

Even elves are like this, let alone humans.

The problem facing Tang En is now very clear. If the accuracy of industrial processing cannot be further improved, the mass production of magic pistols will be just a mirror.

Of course, Tang En can process the magic circle according to its original shape, then use deformation technique to reduce it and then make it constant - but how efficient can he be alone?

Therefore, processing 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, mold accuracy issues, substrate material issues, etc., they all need to be solved step by step, and many of the problems involved in this cannot be achieved in one step.

For example, when it comes to the problem of the mother machine of the magic array stamping machine, Tang En can certainly use alchemy to create a stamping machine with higher processing accuracy, but they do not have observation technology and cannot further improve industrial processing skills. In the future, they will still blindly encounter such problems.

So what needs to be solved now is actually to improve Plandal's observation scale, increase the centimeter and millimeter-level observation technology to the micron level. After realizing 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 scientific and technological tree.

Tang En didn't know much about the specific techniques of microscopes, but he just knew a rough idea. He was just an ordinary college graduate with extensive knowledge, and he had been graduating for many years. It would be great to recall some of the principles.

On Earth, a thousand times optical 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 the resolution of optical microscopes had limits. This limit of resolution limits the infinite increase in magnification, and 1,600 times became the highest limit of magnification of optical microscopes, which greatly restricted the application of morphology in many fields.

Although optical microscopes are not as good as electron microscopes, don't think about electron microscopes. If he had that kind of knowledge reserve, he would probably have gone to heaven long ago.

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

At present, Tang En has never heard of Plandal having magic similar to microscopes. The effect of the talented Hawkeye technique is the effect of the telescope. Here, the corresponding optical phenomena and principles have not been noticed at all, so now he is going to be a charlatan again.

Looking at the busy staff in the research institute and Pamela with a troubled look on her face, Donn thought for a moment and said, "I wonder if you have ever heard of the principle of lenses?"

"Lens principle?"

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

"Don't call me a master! I can't call it a master...the principle of lens? I seem to have heard similar words somewhere."

Nokia put down his work, frowned and said, "I can't remember where I have seen this word, it seems that it was recorded in the document excavated in some ruins."

Tang En smiled slightly. The dwarfs must have pointed out this technology in the past, otherwise they would not have created a nuclear bomb to board Plandal's satellite.

"The principle of lens is very simple. Have you ever paid attention to soap bubbles?"

“Soap bubbles?”

A group of people shook their heads. The soap was made by Tang En. It has only been popularized as a daily necessity recently. People only noticed the convenience of soap, so how could they pay attention to soap bubbles?

"Uh, okay, then another example."

Tang En thought for a moment, put down Yiliya, 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 brought a group of curious babies to the yard. After glanced at the Lumbica (the sun) in the sky, he asked Nokia to get some hay and put it on the ground. Then he pointed to the convex lens floating beside him and said, "This is a typical convex lens, and its function is to gather the beam of light."

"Concentrate the beam?"

A group of people are confused again. Light is light, can it still gather?

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

He adjusted the position of the lens, letting the focus fall on the hay, and said, "You guys pay attention."

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

"That spot is the gathered beam of light, its temperature is very high, but it is only in the focus of the lens."

Because the ice lens he pinched out was very large, the refractive index was very strong. When Tang En spoke, the hay began to smoke. As soon as he finished speaking, the hay was already "bang" and burned.

"It actually caught fire!?"

A group of people were shocked. They obviously didn't see the lord using spells, but just used a strange "lens", and the hay was ignited?

"Yes, as I said, at the focal point of the lens, all the light passing through the lens is refracted at a point, so the temperature there is very high, and it is completely possible to use it for ignition."

Tang En explained patiently, then he lowered the lens, smiled slightly, and said, "But that was the principle of another field just now. Now what you are looking at... the world after passing through the lens, come and take a look."

Pamela took a step forward, looked down through the lens, and then she was stunned.

"What's wrong? I want to see it too!"

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

Tang En laughed silently, and with a thought, the soil rolled under Nokia's feet, lifted him up. Nokia couldn't wait to look over, and then screamed unexpectedly: "Oh my god! This, this, is this the principle of the 'Engineering Master Glasses' recorded in the literature!? It's so simple!?"

Tang En was stunned: "Engineering Master Glasses? Are Dwarf X-ray Glasses?"

"Yes! No!"

The excited Nokia shouted, "In a ruin we excavated, a surviving document records that in the past civilization, one of the essential auxiliary tools for a real engineering expert, a tool that can be worn on the eyes, which can help engineers perform precise processing work - but we have not found any prototype for reference! It is still a difficult problem to solve until now!"

Nokia said excitedly: "I can't imagine that the principle is so simple! Light! Lens! This is the secret!"

Tang En breathed a sigh of relief. It would be better to have a scientific race, otherwise he would have to work hard to explain the detailed principles, which would be even more troublesome.

"Yes, that's it."

Tang En nodded: "In addition to convex lenses, there are concave lenses, single-sided convex lenses, etc.... The most important thing is, if you combine these, you will find a brand new world."
