LOL: I am a bad prince in Demacia.

Lu Qi and others left the palace, got on the carriage, and set off in the direction of the Research Institute.

The carriage drove for a while, and after about thirty minutes, it slowly stopped.

Lu Qi got off the carriage first and saw the base of the Research Institute. It was a large building with a unique style and a bit of engineering feel.

There were also guards guarding the gate. When they saw it was Lu Qi, they bowed respectfully.

One of the guards asked: "Your Highness, what are you doing here?"

Lu Qi looked at him and said, "Take me to see the dean."

The guard turned around when he heard this: "Follow me."

After following the guard leading the way into the hall, you can see a statue in the center that looks very familiar.

After taking a closer look, Lu Qi remembered that he had seen the same statue in the Menke family before, so the identity of this statue was probably that of Durang.

It's just that the Du Lang here looks older, his eyes look wiser, he has an open book in his hand, and his temperament is quite elegant.

Lu Qi withdrew his gaze and looked into the hall. There were people coming and going in the hall. Except for the patrolling guards, the rest were basically scholars from the scientific research institute.

"This way."

The guard turned to the right.

The scientific research institute is not small, with several areas. On the way, I encountered many people walking in a hurry, looking very busy.

The three of them, Navis, looked at the inside of the Research Institute curiously from beginning to end. Even though they were descendants of the Menke family, they were not usually qualified to enter a place like the Research Institute.

Those who can enter here are either soldiers protecting security, or people with a particularly noble status like Lu Qi.

The last one is based on strength.

Not to mention Navis, Meili and Keson are definitely not qualified.

After some guidance, several people finally arrived in front of the dean's office.

The guard raised his hand and knocked on the door and said: "Dean, the prince is here."

After the words fell, the door was opened immediately. A middle-aged man took one look and said: "Your Highness, please come in. The rest of you can wait outside."

With that said, he gave up his position.

Lu Qi walked in, but Navis and the other three didn't actually want to follow them in, so they waited outside.

"Your Highness, please follow me."

After entering the room, there were several rooms inside. The man who opened the door led Lu Qi to the left.

Pushing open a door, I saw a man bending down inside, holding a tool in his hand, studying something. He wore a monocle and a loose robe, and looked about forty years old.

This person is the dean of the Research Institute.

On the way here, Lu Qi learned from sister Mei Li that the current director of the scientific research institute is also from the Menke family.

His name was Winward Durand Menke. He was the third eldest child in his family and had no heirs. He was only forty years old and already served as the dean of the Research Institute. His ability was very outstanding.

And he is also the uncle of the three Navis.

Looking further down, Lu Qi discovered that what Wynward was studying was the microphone pipe and its internal accessories.

At this time, the man who opened the door just now retreated.

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

With an expression of admiration on his face, Wenhuade put down the tools in his hands as he spoke, looked at Lu Qi, and saluted, "This is our first meeting, Your Highness."

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

"The Marshal has just informed me of the purpose of your trip."

Wenhuade said slowly, "Of course it's no problem to borrow someone, but before that, I have a few questions to ask you."

Even as an elder, his attitude remains humble.

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

Lu Qi heard this and said, "What's the problem?"

"Just like this." Wynward reached out and picked up 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 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 surprised him extremely.

He basically spends his time doing research and inventions, and never cares about family affairs. After hearing the news, the first thing he thought of was to find out about it from Navis.

But later I heard that the person who inspired Navis was the second prince of this country.

So, he suppressed his curiosity and decided to do some research on his own to see if he could understand the so-called voice before the prince came to him.

But the result is obvious. Apart from a piece of information obtained from the marshal, he has no new inspiration so far.

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

Wenhuade asked with curiosity in his eyes: "Why do you say that?"

"Take the microphone as an example."

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

"resonance?"

Wynward suddenly fell into thinking, and he was trying to understand what Lu Qi said.

After a few seconds, he looked at Lu Qi: "In other words, you use resonance to make the sound drive the vibration of another object when it propagates, and so on. So sound is also a kind of energy."

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

There is a lot of energy in nature, including light energy, water energy, mechanical energy, and electrical energy. These are all energies that have the ability to drive matter.

Human beings have used this energy to achieve many things.

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

So that's the case, then this makes sense.

"If you put it this way, the sound can definitely be used in other places."

Wynward walked around on the ground talking to himself. He seemed to be enlightened and thought of something, "Sound is a kind of energy. Can this energy be used as a weapon?"

Lu Qi, who was on the side, felt a little emotional when he heard this.

Sure enough, there is no shortage of talented people wherever you go.

It is said that Wynward is already the dean at the age of thirty-five. It is indeed true that he can sit in this position at such a young age.

He only said a few words in total, and now Wynward understood it and began to deduce other uses of sound.

Looking at Wynward who was thinking about himself, Lu Qi thought for a moment and said proactively: "You can imagine that sound is a pressure wave. When you play a musical instrument, slap a door, or knock on the table, their vibrations will cause the medium to --The rhythmic vibration of air molecules causes density changes in the surrounding air, forming longitudinal waves of alternating density and density, which produce sound waves."
