lol: I was a bad prince in Demacia

And he was also the uncle of Navis and the others.

Looking further down, Lu Qi found that what Wen Huade was studying was the microphone pipe and its internal accessories.

At this moment, the man who had just opened the door backed out.

"I have to say that the design of this sound transmission device is very delicate. If it were me, I might not have such an idea."

With a look of admiration on his face, Wen Huade put down the tools in his hand, looked at Lu Qi, and saluted, "Nice meeting, Your Highness."

Lu Qi replied with the courtesy of a junior: "Good afternoon, Dean."

"Just now, the Marshal has informed me of the purpose of your trip."

Wen Huade said slowly at this time, "Of course it's okay to borrow someone, but before that, I have a few questions I want to ask you."

Even as an elder, his attitude is still humble.

When he spoke, there was a studious look in his eyes.

Lu Qi asked, "What's the problem?"

"Like this." Wen Huade reached out to pick up the microphone of the microphone, "I originally wanted to ask Navis, but after thinking about it, it's better to ask you directly. Can you tell me what the sound is? "

As the dean of the scientific research institute, he naturally knew about the microphone pipeline right away.

And he heard that it was developed by a junior in the family, which made him extremely surprised.

He spent most of his time researching and inventing, and never cared about family matters. The first thing he thought of after hearing the news was to ask Navis for clarification.

But I heard later that it was the second prince of this country who inspired Navise.

So, he held back his curiosity and decided to study for a while before the prince came to him, to see if he could gain insight into the so-called voice.

However, it turned out that apart from a piece of information obtained from the marshal, he had no new inspiration so far.

Faced with this question, Lu Qi also thought about it, and replied: "Sound is actually a kind of energy."

Wen Huade asked curiously, "Why do you say that?"

"Take the microphone as an example."

Lu Qi took two steps, came to this small workbench, picked up a microphone, and said, "For example, if two objects with the same frequency hit one of them, the other object will also vibrate and make a sound. It’s called resonance. And the device inside the pipe uses the characteristics of sound resonance to achieve long-distance transmission.”

"resonance?"

Wen Huade suddenly fell into thinking, he was trying to understand Lu Qi's words.

A few seconds later, he looked at Lu Qi: "That is to say, you use resonance to make the sound drive the vibration of another object when it propagates, and repeat this...so sound is also a kind of energy."

It was more like he was talking to himself, as if he gradually understood the meaning.

There are many energies in nature, such as light energy, water energy, mechanical energy, and electrical energy, all of which are energy and have the ability to drive matter.

Human beings use these energies to achieve many things.

But he never considered that sound is also a kind of energy.

It turned out to be like this, then this makes sense.

"If you say that, the sound can definitely be used in other places."

Wen Huade walked on the ground talking to himself, he seemed to be enlightened, and thought of something, "Sound is a kind of energy, so can this energy be used as a weapon?"

Lu Qi, who was at the side, was also a little emotional when he heard the words.

Sure enough, there is no shortage of talented people anywhere.

It is said that Wen Huade is already the dean at the age of 35. It is indeed not unreal to be able to sit in this position at such a young age.

He said a few words in total, and now Wen Huade has understood, and began to deduce other uses of the sound by himself.

Looking at Wen Huade who was thinking about himself, Lu Qi thought for a while, and said actively: "You can imagine that sound is a kind of pressure wave. When playing a musical instrument, knocking on a door or knocking on the table, their vibration will cause the medium --The rhythmic vibration of air molecules makes the surrounding air change in density, forming longitudinal waves with alternating density and density, which produces sound waves."

Wen Huade's eyes lit up: "That is to say, when this pressure wave is strengthened, the energy that the sound wave can generate will be greater."

And when the energy of the sound wave is large enough, it will naturally form an offensive weapon.

Thinking of this, he suddenly looked at Lu Qi, like a junior looking at an elder, and said seriously: "I have been taught."

"You're welcome." Lu Qi smiled, "Do you have any other questions?"

So Wen Huade continued to ask: "Then how to enhance this sound wave?"

After thinking about it, Lu Qi walked to the blackboard on the right side of the room, picked up a piece of chalk, and wrote on it: "The number of times an object vibrates within one second is called frequency, and the unit is called by Hertz." ..."

It is not difficult to see that Wen Huade's direction is to develop sonic weapons.

In fact, with the current capabilities of Demacia, it is extremely difficult to develop sonic weapons, and it is better to pick up an atomic bomb for nothing.

However, Lu Qi didn't think it was a waste of time.

He also doesn't mind bringing what he knows to Debang.

Especially people like Wen Huade and Navis who are extremely obsessed with science.It is often this kind of person who can bring great changes to an era in a very short period of time.

Even if they knew it was far away, at least they knew the direction.

Time passed by minute by minute.

At the same time, the dean went outside.

"Why are you here?"

Seeing the three of them, a curly-haired man stepped forward and asked with a frown.

When the three of them saw the man, they were also slightly taken aback, then bowed their heads together and said hello: "Brother Jared."

Jared said lightly: "This is the scientific research institute, is this the place you should come to?"

He is the eldest son in the family, seeing him, the aura of the three of them is inherently much weaker.

At this time, upon hearing this, Meili also replied: "We came down with the prince."

"His Royal Highness..."

Hearing this, Jared's expression did not change. He glanced at the three of them, especially after seeing Navis, his brows frowned even deeper, "It seems that you still haven't listened to me. As I said, it's best not to talk to Navis." Such useless people messing around."

At this moment, he looked at Navis' expression rather displeased.

After he came back from a business trip, he learned that his exclusive workshop had been occupied, and Navis was the one who occupied it.

Immediately afterwards, he learned that the person who gave such an order was His Royal Highness, so he naturally couldn't ask Lu Qi for an explanation.

His Royal Highness couldn't afford to offend her, so the anger naturally fell to Navis.

However, Navis didn't even return to the Menke family these days, which left Jared with nowhere to vent his anger.

When I saw it today, I must have to vent my anger.

Moreover, the two siblings, Mei Li and Ke Sen, who followed him all day on weekdays, also ran out all day. After learning that they were looking for Navis, Jared directly forbade them to have any further contact with her.

However, it seemed that the two did not listen.

If it were normal, Mei Li and Ke Sen would already be trembling with fear, but now thinking of their backer, they are also a little bit more confident.

Meili said with a firmer tone, "Why do we have to listen to what you say?"

Ke Sen also nodded beside him and said, "That's right, Navis is not a useless person."

At this moment, the two of them are hard on Jared, not only because of Lu Qi's backing, but also because they have discovered many advantages of Navis after getting along these days, and they also realized how stupid they were before.

Navis raised her head and glanced at the two of them, her eyes were touched.

Even if she doesn't go out all the year round, she knows that Jared, as the accomplished eldest son of the younger generation of the Menke family, basically no one dares to say one thing among the younger generation.

But now the siblings are willing to stand on the opposite side of Jared for her.

"It's ridiculous, don't think that your wings are hard because you are with His Royal Highness. I really can't think of a reason why he values ​​you, but I also want to thank him for being willing to take you three burdens."

Seeing the behavior of the siblings who usually dare not resist him, Jared smiled contemptuously and said indifferently.

Glancing at the three of them with disdain, Jared turned and left directly, unwilling to waste time on them.

In his eyes, Navis was always an outsider who wasted family resources.

As for Mei Li and Corson, they are just two idiots, there is nothing to say.

In his opinion, the three of them will never be able to enter the scientific research institute in this life.

Navis was used to such humiliation, Meili and Corson didn't look very good, but they couldn't refute it.

They are also a little used to it, Jared is so proud and defiant in the family.

After all, the Menke family speaks with ability, and the more capable a person is, the higher the right to speak in the family.

Not long after, Lu Qi opened the door and walked out.

At a glance, he noticed that the atmosphere on Navis's side was not right. It was normal for Navis to keep her head down, but Mei Li and Ke Sen had a downcast expression.

After thinking about it, I still asked, "What's wrong?"

Obviously something happened here, otherwise the two siblings who were very excited before coming here have completely changed.

"Brother Jared was here just now."

"Jared?"

Lu Qi's impression of this person remained the same as what he knew last time. It seemed that he threatened Navis in the family as an outsider and took the lead in isolating and bullying.

So what happened just now, even if the three of them didn't say anything, Lu Qi probably guessed it.

At this time, two voices came down from the top of the head.

"All academy students, assemble in the conference hall!"

"All academy students, assemble in the conference hall!"

Lu Qi looked up at the source of the sound, and found a loudspeaker hanging in the corner.

Wen Huade walked out of the dean's room and said with a smile: "Does your Highness look familiar?"

Lu Qi nodded, he saw that this thing seemed to be a microphone.

Even at this moment, even he was a little surprised at the efficiency of the research institute.

Apparently, they used the microphone as a broadcast-style loudspeaker to talk to everyone unilaterally, which is very convenient in this kind of workplace.

Of course, this is also a usage in itself.

The last time Tiana took Lu Qi to find Navis and entered the palace, it was to understand the blueprint and principle of the microphone clearly.

After sending it to the Academy of Sciences, I told Lu Qi in advance.

However, it's only been a few days.

It is not easy for the scientific research institute to use it and find other uses in such a short period of time.

"Uncle Windward."

At this moment, the three of Navise bowed to Wen Huade and said hello.

"Let's go."

Wen Huade looked at them and smiled. He has no heirs, and he doesn't care much about family affairs.

But now, in his opinion, it is a kind of great luck for the juniors of these three families to meet His Royal Highness the Prince.

He thought maybe he could be promoted a little bit.

Several people were walking on the way to the meeting room, and Lu Qi also saw several loudspeakers used to project sound, as well as many academy students who were rushing towards the meeting room.

By the time they arrived, the students in the conference room had basically arrived.

"Hello, Dean."

After seeing Wen Huade, the people inside all stood up and said hello.

"All sit down."

Wen Huade waved his hand, looked at Lu Qi and said, "Do it for a while, I still have something to say before that."

So Lu Qi sat in the front row.

The three of Navis also sat beside them.

At this time, Wen Huade walked to the stage in front of the conference hall, looked at everyone and said slowly: "The results of the last round of examinations of the Academy of Sciences have come out today, and those who I can read their names next, come on stage."

He didn't talk too much nonsense, and after he finished speaking, he read it directly.
