It's not that hard to open a hospital in another world, right?

Chapter 775 Shielding Suit?Hide the patent, or sell it? (7 rewards plus [-])

Gretel held the gem, honestly accompanied the last seat, and listened to the recent research progress of the brothers and sisters.In the palm of his hand, the heavy warmth and vitality kept reminding him:
The use of mental power still needs to be practiced, and it has to be practiced all the time.This time it's a lightning maze, the next time I'm caught by the teacher and don't practice well, I won't be able to tell what kind of maze it is——

Maybe it's flames, ice, light, lightning, acid, sound waves, force fields, multi-type attacks, surrounded on all sides, and watched him roll and crawl together.At that time, there will be no such good thing as a shielding suit...

"Grete!"

"Huh? Teacher?"

"What's the matter with your clothes? Without any spell fluctuations, it can resist 2-ring electric magic-why didn't I see your paper?"

"This is very simple..."

The teacher's eyes swept over like cold electricity.Gretel quickly changed his words:

"Okay, teacher, I will write it as soon as possible! It must be handed in next week's regular meeting!"

It's over, and I added another one to the to-do list... I don't know if the teacher will be angry if Aurora is asked to write this paper... What is the principle of the Faraday cage?
Equal potential?

The concept of electric potential, where has the research progressed in this world?

As soon as the regular meeting was over, Gretel left the teacher's office and stuck directly to Senior Sister Philby's side.Step by step, the senior sister's disciples, one by one, were pushed to the back by him.

"What's the matter? Do you want me to write it for you? It's not allowed~~~" Senior Senior Sister glanced over leisurely, her eyes shifted, her smile was half a smile.Gretel took another step closer cheekily:
"Senior Sister~~~ Please give me a make-up theory class! Don't you want this dress? Do you really don't want it?"

Without any spell fluctuations, it can resist the second ring lightning magic!Which magician doesn't want it?In case the magic defense is broken, this is the last line of defense!

"No. Ugly."

Senior Sister answered directly.The tone was so crisp and sharp that Gretel's eyes went dark:
"..."

How ugly!
How ugly!

Although it is not the robe form that magicians are used to, but the jacket and trousers are separated into two parts, which looks like it is worn by manual labor workers;

The tailoring does not have the slightest waist, modifying the body shape, round and fat, and the whole person is fatter when wearing it;
No dyeing, no embroidery, no pockets, buttons, chains, or any decorations, the whole thing is dusty, not much different from the linen clothes worn by the poor...

Well, it's ugly.But this is functional clothing, not decorative, senior sister, you can't use fashion requirements to get stuck on it!

"So little Gretel, what's the reason for this dress?" Senior Brother Bairbo said with a smile coming from afar:
"Don't listen to your senior sister. If she doesn't talk about it, I'll talk about it. If this thing is convenient to make, you can have a set, and then give each of those boys a pair. At least it can stop them from committing suicide, right?"

"Hey!"

The two archmages turned their heads and stared at each other.Crackling, crackling, electric sparks quietly exploded.Gretel silently bowed his head and stood aside:
This thing is very simple to make!
Don't pull me up!
I can't stop you two archmages above level 16 from fighting on the spot!
In the end, Archmage Philby coerced Gretel into her laboratory on the grounds that "I am in the direction of electromagnetism, and the study of electric spells is my specialty."And senior brother, with the white eyes of Archmage Philbi, swaggered after him:
Taking off the shielding suit on Gretel, Archmage Philby couldn't wait, and pointed at it.Zizizizizi, the electric light flows.The two archmages stood side by side, one on the left and one on the right, their eyes lit up at the same time.

Gretel also imitated them, letting go of his mental power to feel the lightning flowing on the shielding suit.

In the induction of spiritual power, powerful electric energy gushed out from the archmage's fingertips, fell on the shielding suit, and immediately dispersed into countless threads.Along the thin silver threads in the fabric, it rushes to every corner of the clothes.

Then, hovering over the silver wire, but not a little leaked inside.

Two sharp eyes fell on Gretel.Gretel quickly raised his hand:
"I said, I said. The principle is—"

"You don't need to explain the principle!" The brothers and sisters said in unison:
"Tell me how to do it!"

"Okay, okay... Actually, it is to use very thin silver wire mixed with flame-retardant fibers—I used asbestos wire—to make a piece of clothing." Gretel quickly explained the method:
"Clothes, pants, shoes, hoods, all connected. Try to connect as many as possible so that the current can be evenly distributed to every place."

"It looks very convenient."

"Yes, and I don't use much silver wire." Archmage Philbi waved, and the hand of the mage flew over, picked up the protective suit and weighed it:

"It's not too heavy. The whole suit weighs just over four pounds. Less than half of the silver thread is used in it... um..."

Two pounds of silver is only thirty or forty silver coins.The laboratory can still afford this amount of money.Not to mention that the laboratory can afford it, everyone can afford the magician who is qualified to enter the archmage's laboratory.

As for asbestos silk, ha, that counts as money?

Gretel shook his head slightly.The principle of the shielding suit is not difficult - of course, how to write it is another matter - the design is also simple.However, to make a finished product, the technical difficulties involved are another matter.

"The key is that the silver wire must be pure. If there are impurities, the resistance will be high. And it must be drawn very finely and evenly. As long as it is uneven, the resistance will be different, and the same current will have different voltage. If it is not the same, it will easily break down. ..."

Archmage Philby frowned slightly, and suddenly waved.From somewhere nearby, a silver cup flew over. During the flight, it quickly deformed and softened.Pull out a hair-thin silver wire, connect one end to the mouth of the cup, and the other end to the foot of the cup.

A dozen or so roots are smooth and even, and there are still a dozen or so roots that are lumpy and uneven in thickness.Obviously, the archmage deliberately controlled it for comparison.

A scream sounded from a distance:
"My cup! Ah, teacher..."

Stop calling halfway.Archmage Philbi waved his hand again as if he was unknown, and an electric bead flew out from his fingertip, which split into small beads in mid-air and dropped on each silver wire separately.

The lightning flashed in an instant.The archmage stared at the electric current without blinking, and nodded slightly:
"You're right. The silver wire is drawn unevenly. As long as the difference in diameter exceeds one-tenth, there will be a significant difference. Tsk, such a thin silver wire..."

"I asked Master Norwood, the fifth-level transformation mage in our mage tower, to help me." Gretel added an explanation at the right time:

"If low-level alchemists, or even ordinary people, are to be able to participate in the production, then the processing precision required will be greatly improved. Perhaps, we need to talk to the alchemist union..."

The two archmages frowned at the same time.Master Norwood is a follower of Gretel, and it is normal to help him make something casually without charging any money; it is impossible to make large quantities of shielding suits for the Lord of Thunder without charging money.

Let a fifth-level transformation mage do these by himself?
Is the laboratory's finances sustainable?Or let these mages think a little bit more and forget about it, hang up the defense, and they deserve to be electrocuted if they don't put up the defense?

Gretel turned his head silently.The shielding suit made by Mage Norwood, if the cost is based on the cost of a fifth-level mage, 500 gold coins for a set is a friendly price.In mass production, it can be pressed down to two or three hundred gold coins, and it cannot be pressed down any more.

It can be replaced with the previous life, 500 kV high-voltage shielding suit, two sets of 3000 people RMB.It is lighter than it, the voltage is higher than it can withstand, and it lasts longer than it...

The power of large-scale industrialization really exceeds that of small workshop-style handicrafts. There are too many!

"Actually, this kind of silver thread not only has to be drawn very thin, but also doesn't last long." Gretel continued to pour cold water on them:

"Silver is easy to oxidize. Once oxidized, the resistance will not meet the standard. When the resistance is high, heat will be generated when the current passes through, and it will burn quickly. Even if it does not burn, it will not have the shielding effect."

Moreover, the finer the silver wire, the larger the specific surface area.The larger the specific surface area, the faster the overall material oxidizes...

"This shielding suit of mine was just made last week. I made two pieces together. The first piece was covered with dolls and experimental animals. After a round of experiments, after a round of attacks by me and Aurora, there was nothing wrong with it." I used it. It was later discovered that the silver wire was too thin and broke.”

The two archmages looked at each other, and then heaved a long sigh.Archmage Philby spread his hands:
"Forget it. Little Gretel, don't you want to listen to the principles of electricity spells? Come!"

Gretel moved a stool, obediently listened to the lecture, and went back after filling his head with spells, elements, and magic circles.Thankfully, in this world, there is already a concept of "electric potential"——

Although the understanding of the magicians is that the lightning falling from the sky falls from a relatively high potential energy to a relatively low potential energy.Powerful lightning magicians can directly perceive it with their spiritual power.

It's like they sense the electrical potential on the shield suit.When a beam of current falls, in an instant, a uniform and stable electric field can be achieved on each silver wire of the entire shielding suit.

Gretel put away the shielding suit, said goodbye happily, and left.With the explanation of the senior sister, this paper can be submitted in two days!It doesn't take a week!
Senior Sister is a great person!It saved him too much time to search for information!
He swayed and walked lightly, almost humming a little song.In the laboratory, the two archmages looked at each other for a while and discussed in a low voice:
"This paper, is it recommended that he publish it?"

"...I don't think it is necessary. For our Thunder Horn, especially the Thunder branch, the weakening is too great. The second-level spells will be abolished immediately! It is silent, without spell fluctuations, and you can't even defend against it! "

"I don't think it's okay to take it out. As Little Gretel said, the cost is too high and it's too easy to scrap. So what if we let them explore slowly?"

"Don't worry, they are all our own people. Or, can we publish the paper and let the parliament know privately?"

"Forget it... Let's ask the teacher to persuade him not to publish the paper. As for the loss, let's make up for it each?"
