"Big Brother!"
When Elijah saw Tang En, she pounced on him without a word. Then, she raised her head and stared at Tang En fiercely. Tang En actually saw a hidden bitterness in her eyes.
What the hell!? She's still a child!
"Elijah, you've worked hard. I heard that with your help, the research facility's progress has been very fast?"
Before Elijah could speak, Pamela smiled and said, "Indeed. Elijah's magical talent is unparalleled. It's really hard to imagine that she's just a little human girl. With her help, we've successfully replicated the topology of the magic array, but now there's a new problem."
Pamela didn't know Elijah's true identity.
Ilya, who had her words stolen, pouted and buried her head in Twain's arms, not saying a word.
Tang En ruffled her hair and asked Pamela, "The magic array has been replicated. Are there any other problems?"
"The magic array press that you provided."
Pamela paused for a moment, then slowly said, "I have to say that this idea of yours has provided a convenient way to engrave magic arrays in batches. It's practically a genius idea. However, there's a problem now. The miniature magic array you modified is too small. The precision of the magic array press can't meet the processing requirements. We've tried many times, but the success rate is very low. Most of the time, because of the instability of the magic array channel, mana overflows and then explodes."
"Mana overflows?"
"Yes. Because of the precision of the press and the base material of the magic array, the magic array can't be formed with the precision that you can engrave manually. Because of the instability of the magic array channel, after laying down the magic dust, we observed mana turbulence forming in the channel. After activating the magic array, the mana turbulence caused the magic array to become unstable … "
Pamela's voice had the unique rhythm of the elven language. It was very comfortable to listen to. Although she spoke slowly, her meaning was clearly conveyed to Tang En.
"In the end, is it still a problem of processing precision?"
Tang En frowned slightly. The industrial foundation of Prandal was very poor. Of course, the micro-sculpting technology could not be counted on. Not to mention the CPU immersive light sculpting technology on Earth, which could easily reach a few nanometers, it was already very difficult to achieve precision processing at the millimeter level.
The magic array press that Tang En designed and built was only made to adapt to the production of magic furniture. Those magic furniture were very large, so there was no problem in this area.
And now, the appearance of the Mana Pistol had magnified this problem.
"That's right. Even though we've tried all kinds of methods, we still haven't been able to solve the problem of mana overflowing."
Pamela was also very troubled by this problem. As an elven scholar, she obviously knew that miniaturizing a magic circle was very difficult, but why was it so difficult after miniaturization? She only knew that miniaturization would cause the mana channel to be unstable. As for why it was unstable, she could not explain it.
Even the elves were like this, let alone the humans.
Now, the problem in front of Tang En was very clear. If the precision of industrial processing could not be improved, mass production of the Mana Pistol would just be a fantasy.
Tang En could of course process the magic circle according to its original shape, then use transfiguration to shrink it, and then make it permanent. But how efficient could he be alone?
Therefore, processing precision was a key technology that had to be solved!
However, the problem of processing precision involved a lot of things. Whether it was the microscopic observation technology, the precision of the mold, the material of the substrate, and so on, they all needed to be solved step by step. Moreover, many of the problems involved couldn't be solved in one go.
For example, regarding the problem of the magic array stamping machine, Tang En could certainly manually use alchemy to create a stamping machine with a higher processing precision. However, they did not have the observation technology and could not further improve their industrial processing skills. In the future, when they encountered such a problem, they would still be at a loss.
Therefore, what needed to be solved now was actually to improve Prandal's observation scale, to improve the observation technology from the centimeter and millimeter level to the micrometer level. After understanding the microscopic world, they would naturally notice the problem and the technical direction that needed to be improved. Then, they would naturally point out the corresponding technology tree.
Tang En was not very clear about the specific technology of the microscope. He only had a general idea. He was just an ordinary university graduate with a broad range of knowledge, and had graduated many years ago. It was already good enough that he could remember some of the principles.
On Earth, the optical microscope was invented in the eighteenth century. It allowed 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 realized that there was a limit to the resolution of an optical microscope. The limit of resolution limited the unlimited increase of magnification. 1600 times became the highest magnification limit of an optical microscope, which greatly limited the application of morphology in many fields.
Although the optical microscope was not as good as the electron microscope, the electron microscope was out of the question. If he had that kind of knowledge, he would have been in heaven by now.
The discovery of the microscope helped people understand the microscopic world and greatly expanded the development process of biology, physics, and materials science. Every time the scope of observation was improved, it would bring about a rapid development of science and technology. This showed the importance of observation technology.
Currently, Tang En had not heard of Prandal magic that was similar to the microscope. The effect of his talent, Eagle Eye, was the effect of a telescope. Here, the corresponding optical phenomena and principles were not noticed at all. So now, he had to play the role of a charlatan again.
Looking at the busy staff in the research institute and the troubled Pamela, Tang En pondered for a moment before saying, "Have you ever heard of the lens principle?"
"The lens principle?"
Pamela was confused. She turned to Nokia and shouted, "Master Nokia, have you heard of the lens principle?"
"Don't call me master! I'm not a master yet … The lens principle? I seem to have heard of a similar term somewhere. "
Nokia put down his work and walked over with a frown. "I can't remember where I've seen this term before. It seems to have been recorded in a document excavated from some ancient ruins."
Tang En smiled. The dwarves must have mentioned this technology in the past. Otherwise, they would not have been able to create a nuclear bomb and land on a Prandal satellite.
"The lens principle is very simple. Have you guys noticed soap bubbles?"
"Soap bubbles?"
The group shook their heads. Soap was invented by Tang En. It was only recently popularized as a daily product. People only cared about the convenience of soap and did not pay attention to soap bubbles.
"Uh, okay, then let's change an example."
Tang En thought for a moment. He put down Elijah and snapped his fingers. The water elements in the air quickly condensed and formed a convex lens that was thick in the center and thin on both sides according to his will.
Then he brought the group of curious babies to the yard. After glancing at the Lun Pika (the sun) in the sky, he asked Nokia to bring some hay and put it on the ground. Then he pointed at the convex lens floating beside him and said, "This is a typical convex lens. Its purpose is to gather light."
"Gather light?"
The group was confused again. Light was light. How could it gather light?
Tang En was not in a hurry to explain. After they finished watching the experiment, they would naturally understand.
He adjusted the position of the lens so that the focus was on the hay. Then he said, "Look carefully."
The group stared at the hay and was surprised to see a very bright spot of light suddenly appear on the hay.
"That light spot is the gathered light. Its temperature is very high, but only at the focus of the lens."
Because the ice lens was very large, its refractive index was very high. When Tang En spoke, the hay had already started to smoke. Just as he finished speaking, the hay had already started to burn with a light bang.
"It's on fire!?"
The group was shocked. They did not see the Lord use any magic. He only used a strange "lens," and the hay was set on fire?
"That's right. Just as I said, at the focus of the lens, all the light that passes through the lens is refracted at one point. So the temperature there is very high. It can be used to light a fire."
Tang En patiently explained. Then he lowered the lens and smiled. "But that was the principle of another field. Now I want you to see... the world after the lens. Come and take a look."
Pamela took a step forward and lowered her head to look through the lens. Then, she froze.
"What's wrong? I want to see too! "
Nokia, who was the most interested in new things, jumped and shouted, "You are discriminating against the height of dwarves!"
Tang En laughed involuntarily. With a thought, the soil under Nokia's feet rolled, and he was lifted up. Nokia looked over impatiently, and then, without warning, he screamed, "Oh my God! This, this, this is the principle of the 'Master Engineer Glasses' recorded in the literature!? It's actually so simple!? "
Tang En was stunned. "Master Engineer Glasses? Dwarven X-ray glasses? "
"Yes! No! "
Nokia excitedly waved his hands and shouted, "In one of the ruins we excavated, a surviving document recorded that in the past civilization, a true engineer had one of the necessary auxiliary tools. It was a tool that could be worn on the eyes. It could help the master engineer carry out precise processing work. But we did not find any prototype for reference! It is still a difficult problem to solve! "
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 was good to have a race that understood science. Otherwise, he would have to spend a lot of effort to explain the principle, which would be even more troublesome.
"Yes, it's like this."
Tang En nodded. "Besides the convex lens, there are concave lenses, single-sided convex lenses, and so on... Most importantly, if you combine them... you will find a new world."
