When Brandi tested the filament, he only found about 100 kinds of filament materials, and when he arrived at the Academy of Sciences, he directly made a list of more than 1,000 materials to test.

And this is only a part, just some materials in nature, if you add some thin wires made of various metals, I'm afraid no one knows how many materials can be used to make filaments.

In addition, Flandy has briefly mentioned the concept of vacuum, although it is not yet possible to decompose various gases, but a vacuum alone can solve many problems.

Flandy hadn't been to the Imperial Academy for a while, and his presence immediately drew crowds.

These researchers all learned Frandi's theoretical knowledge, and they can be said to be his disciples and students, and in the minds of these people, Frandi has been equated with science.

Although there is no word for idol in this world, in their hearts Frandi is their idol.

"Flandy, do you have time to come over today?" said Senior Barry squeezed out of the crowd.

He was studying some knowledge in his office when he heard something noisy outside, and when he came out, he saw that the crowd was surrounded by black press, and he didn't know what was going on.

But from the conversations of the people, I knew that it was Flandi who came, so I squeezed in.

"Hehe, Senior Barry, I heard that you have researched a new thing, so I came to see it. ”

In fact, Flandi quite enjoys this kind of treatment, just like a star in the previous life, who can make people like you, and it is also a reflection of your value.

Hearing Frandy talk about this, Senior Barry also showed a touch of pride on his face.

Although he didn't research it himself, after all, after all this time, the Academy of Sciences finally made a new thing on its own without the help of Frandy.

Even if this new thing was developed on the phone developed by Frandi, it can be regarded as an innovation after all.

"Yes, it was Candace who came up with it by accident, a device that amplifies people's voices. ”

"Oh, megaphone?" said Flandy, who was not surprised, but just heard what Senior Barry said, and guessed what it was.

"Megaphone? That's a good name, I'll call it a megaphone in the future." Is that Candace there?" said Senior Barry as he shouted at the crowd.

"She's still researching, I saw her working in Lab Three when I came out just now!" a voice came from the crowd.

"Okay, let's all disperse, there are many opportunities to see the dean in the future, and you can't get out of the dean so crowded. ”

After all, these researchers are a group of quality people, although some of them have never met Flandy, and some are curious about what this mysterious dean is like.

But after seeing it, it satisfied my curiosity, and it was really not a problem for so many people to crowd here, so they dispersed in twos and threes.

"Let's go, Flandy, let's go to Lab Three. Senior Barry said as he led the way.

Lab 3 is not in this building, but in the newly built eight-story building on the left.

This building is also equipped with a magic ladder, and because it has to transport some heavy and large things, this magic ladder is relatively large, and more than a dozen people standing in the magic ladder seem very spacious.

It wasn't until I came to the sixth floor that I entered what people called Laboratory No. 3.

This lab occupies almost a third of the entire floor, and it seems that there are only three labs on this floor. The wires of various materials in the room were unconventionally arranged, and there were seven or eight people here who didn't know what they were experimenting with.

Along with Senior Barry, Frandy and the others, there were several researchers from the No. 3 laboratory, who shouted as soon as they entered the door: "Candace, Candace, come here, the dean is looking for you!"

"Ah, Lord Dean, Mr. Flandy?" exclaimed the girl in front of a laboratory table in the corner.

"yes, come here!" said Senior Barry with a smile on his face.

"Immediately, right away, this is coming!, Lord Dean, please wait a moment!" Although the voice revealed surprise, the girl did not come immediately, but continued to do the work in hand.

But it was less than ten seconds before Candace had installed a component and jumped in front of Frandy.

"Hello, Lord Dean, I'm Candace!" The girl was only about twenty years old, about the same age as Flandy, but her eyes were full of adoration.

"Oh, you know my name is Flandie?" asked Flandie, curious.

"Of course, Abba always compliments you every day when he comes home, and my ears are almost calloused!" replied Candace cheerfully.

"Does your Abba know me?"

"Of course, my name is Candace Mottley, and my abba name is Dean Motley. ”

"Dean Motri, Minister of Industry?" Frandy never imagined that the beautiful girl in front of him was actually Minister Dean's daughter.

"Yes, yes, I begged Abba several times to get him to send me to the Academy of Sciences!"

"Oh, you're a magician?" Flandy could feel faint fluctuations in her magic.

"It's a pity that I only have a talent for chaos magic, and I can't do any powerful magic, so I have to be an alchemist. There was a hint of loneliness in Candace's eyes, but it disappeared immediately.

The magic seed of the chaos attribute itself does not have any magic program for attack or defense, and the magic talent of order is the same, it is a supporting one, if there are other attributes of the magic talent is like a tiger, but if it is a single attribute, it is a bit of a chicken rib.

Therefore, magicians with magical talents of these two attributes generally choose to become alchemists.

Flandi knew she was a little disappointed in her magical talents, so she said, "Let's go, look at the megaphone you studied." ”

"Loudspeaker, good!" Candace was overjoyed to hear Frandy mention her latest research.

Frandy and the others followed Candace to her lab table, which was messed up by her, and a delicate little box was placed in the middle of the lab table, connected with several thin lines.

"Look, Flandy, this is the megaphone I made!"

"How do you use it?"

"Good!"

Candace closed a switch, then picked up a small microphone next to her and said inside, "Hello, Frandi, my name is Candace." He smiled playfully.

The voice was indeed amplified, but it was much louder than the childish microphone of the phone that Franky had brought over, but the voice was a little sharp, not so good.

"Yes, it's quite loud. Romandy nodded.

Candace was a little embarrassed: "Actually, there is nothing new, but the microphone of yours is amplified, the current is also strengthened a little bit, and the combination of the microphone and the speaker is actually simpler than the telephone." ”

"It's not the technology that's important, it's the idea that counts, and if you can think of amplifying the sound, it's great. Frandy was not stingy with compliments, and praised Candace a little.

"It's just that the sound is not loud enough, and the sound quality is still poor, have you ever thought about making a bigger speaker?"

"Ah, make it bigger, why do you want that loud sound?" Candace wondered, she just wanted to work on something new, but she had never thought about what it would do.

For example, if you look at this room, if you have loudspeakers installed in all four corners, will you be able to speak softly here, and the whole room will hear it?"

Candace tilted her head and thought for a moment, "Well, that's fun, but it won't disturb other people's research." ”

"......" Franky was speechless.

"Ahh

"Haha, yes, it is of course very useful to put it in the right place, especially when the place is large and there are many people, with it, you don't have to shout and shout your throat hurt. ”

Frankie was a little relieved, it seemed that the Candace girl was not slow to react.

Candace was like an initiation, and Frandy's words made her think of more application scenarios.

"For example, if my father's ministry installs this, if you want to find someone, just let the horn shout, many people will hear it, right?"

"That's right, loudspeakers are used in a wide range of ways, especially for the military. ”

"Army?" Candace didn't really think about the army, but after Flandy mentioned it, she felt that she could indeed play a very important role in the army.

"Looks like I've done a good job!" Candace said cheerfully.

"Come on, Candace, make a loudspeaker earlier, and make it a microphone to speak, the kind that can ring several horns, so that more people can hear, and it will be more valuable. ”

Candace lowered her head and thought for a moment before saying, "It shouldn't be difficult, just adjust the current and connect a few more horns, I will definitely try to make it as soon as possible!"

"Also, the membrane that produces the sound also needs to be replaced, and the sound restoration of the membrane used now is not good, so it must be clearer. Franky made another suggestion.

"What is reduction?" Candace was confused by the new term.

"That is, what your voice says in the microphone, so that others can hear what you said at once in the speaker, this is called reduction. ”

"I see, it's just that I need to experiment with a lot of materials, and if I have to do it alone, it may take a long time. ”

Experimenting with various materials can be a repetitive task, and Candace doesn't want to go through the hassle.
