The turmoil in the group has not subsided due to the death of Eddie and his son. After all, Eddie and his son are only one of the leaders and do not represent the entire stability maintenance team. And now... But with the arrival of His Highness the Third Prince's confidant Yabo, the stability maintenance team is operating at a high speed. It seems that
Big moves are getting ready.
"Mr. Yabo, this is information about the investigation before Team Leader Eddie was killed and the people he contacted."
Andre, another leader of the team, handed the information to Yabo.
It has been several months since Eddie and his son died, but they did not disappear and achieve nothing in these few months, they just changed their direction slightly.
"Currently, the people who are most active in Xia Ya are the Aurora and Chi Yan people. In addition... the people from the Glorious Empire are still unwilling to give up and are stirring up trouble in Xia Ya..."
Yabo looked at the information and looked a little indifferent.
"The power of the Glorious Empire has declined rapidly with the advent of the new era, but it still has a decisive influence in the world. In addition, we have been ruled by the Glorious Empire in Shia more than ten years ago. Even if they are expelled by us now, they still have a decisive influence in the world.
After all, there are too many backups left behind in Shia..."
Andre said.
"Times have changed."
Yabo said calmly: "The old era when the Glorious Empire relied on giant ships and cannons to roam the world is gone forever. The future is in the hands of warriors. Whoever has enough holy land and resources will be able to survive in the new era that has arrived.
Dominate the world!"
"Warrior..."
Andre's level is not high enough, so he cannot understand the true meaning of Yabo's words.
Even if it is as strong as a war-level warrior, it is equivalent to an enhanced tank. The true strength of a country and the outcome of a war are still the comprehensive military strength and economic strength.
"Um!?"
At this time, Yabo, who was looking through the information, seemed to see something: "A hundred miles of sky?"
As he spoke, he carefully looked through the information: "The Baili Changkong is really equivalent to half of General Melbourne's disciples. Eddie made him a target to win over the latent forces of General Melbourne's lineage.
Help him charge in Xia Haizhou... It's a good plan, but as far as I know that group of people are hidden deep and their power is not weak. It will not be easy for Eddie to dig them out."
"We have investigated this Baili Changkong, and Team Leader Eddie was not in Xiaya City when he was killed."
Andre said, adding at the end: "Mr. Yabo thinks this person is suspicious? Then include him in the scope of key investigations?"
"It's okay if he has an alibi. This group of people is quite powerful. Don't talk about me. His Highness the Third Prince doesn't want to be easily provoked."
Yabo said, exposing the matter.
"Actually, there is something about this group of people... On the day of his death, Mr. Eddie asked his assistant to compile a piece of information, a piece of information involving the Aurora Empire."
Andre said and pulled out another document.
Yabo glanced at it and put it aside: "Do you suspect someone from Baili Changkong killed Russell? How is it possible? Eddie looks like he wants to kill someone with a borrowed knife."
For a moment, he seemed to have thought of something again. He picked up the information again, read it carefully for a while, and thought: "The lurking power of General Melbourne's lineage is not small. If we can really win over His Highness's camp..."
After a while, he handed the information to Andre: "Make a copy and find someone to send it anonymously to Attaché Lafite of the Aurora Empire Embassy."
"yes."
…
Shire University.
Professor Zhou Tianwen from the Department of Physics is explaining the knowledge of sound waves vividly.
"There is relative motion between the vibration source and the person, which causes the frequency of the sound heard by the person to change, resulting in a change in pitch, just like the sound of a train or a car whistle. The tone changes significantly from far to near and from near to far. This
This phenomenon is called the Doppler effect.”
"The Doppler effect can be used for diagnosis. When checking the blood flow rate, it can be achieved by emitting an ultrasonic vibration source. The Doppler effect is generated between the vibration source and the relatively moving blood. The blood vessels move with the ultrasonic source, and the wavelength of the reflected wave is compressed.
, as the frequency increases, the wavelength of the reflected wave increases when the blood vessel leaves the sound source, and the frequency decreases. The increase or decrease in the frequency of the reflected wave is proportional to the blood flow rate. This principle is also used for speed measurement."
"The traffic police emits ultrasonic waves with a known frequency to the moving vehicle and simultaneously measures the frequency of the reflected wave. Based on the change in frequency of the reflected wave, the speed of the vehicle can be calculated. In addition, this effect can also be applied to other similar waves.
On the other hand, such as electromagnetic waves, the conclusion that the universe is expanding is calculated based on this effect."
Baili Qingfeng listened to Professor Zhou Tianwen's explanation and patiently took notes.
A class passes quickly without realizing it.
Professors from Charles University always leave directly after class. Baili Qingfeng quickly chased after him: "Professor Zhou, I would like to ask you about the relationship between ultrasonic waves, infrasound waves and resonance."
"Oh, the principle of ultrasonic waves, infrasound waves and resonance is very simple. Go buy an air humidifier. The air humidifier uses the violent vibration of ultrasonic waves to break up the water flow, causing the water flow to form small mist droplets, and then blows it into the room with a fan..."
"I want to understand the relationship between sound waves, electromagnetic waves and bioelectric waves."
Baili Qingfeng said: "We humans have invented radar, sonar, and ultrasonic inspection equipment by observing bats, and can even use ultrasound to shatter stones in the body. So, is it possible for humans to enhance their understanding and understanding of ultrasound and infrasound waves through evolution?
Storage…”
"The core of your question is not about sound waves, but about organ evolution. Human beings' ability to accept sound is only 20 to 20,000 Hz, and frequencies beyond this range are called infrasound and ultrasonic waves. If you really want to evolve a bat-like
For ultrasonic capabilities, you must first solve the information processing capabilities of your brain. Once this problem is solved, the next thing will be easy to handle. But the question is, can the human brain calculate so many changes in sound wave frequencies in such a short time?
.”
The professor smiled and thought Baili Qingfeng was whimsical.
There is no need to answer this question.
"Unless the brain has something like a filter?"
"Yes, the emission of waves is not the problem. The key lies in reception, filtering, encoding, and analysis."
The professor nodded: "As mentioned in the course just now, when the sound waves and electromagnetic waves we emit encounter other objects, they will cause fluctuations. The change in frequency can determine how fast the object is, and the time from transmitting to receiving the wave can calculate how far away it is.
, as long as this frequency change is extracted, you can easily measure distance, speed, and make a radar. If you are really interested in this aspect, prepare a microwave signal source, power splitter, transceiver antenna, high-frequency amplifier, and hybrid
Try frequency converters, filters, low-frequency amplifiers, and signal conversion modules for yourself.”
"I'll try it when I get back."
Baili Qingfeng said.
The professor nodded: "If you have anything you don't understand, you can ask me again. Of course, it's limited to physics."
After the professor left, Baili Qingfeng quickly ran to the electronics market and searched for related instruments.
By the time he reached the sixth divine transformation, the Thunder Lord was able to barely control his own bioelectric field. Since then, he has been thinking about developing a set of sonic martial arts to deal with enemies in a wide range through sonic resonance.
But after all, he is a peace-loving, kind and upright person.
Attacking the secret method was too violent and was not his original intention. What he wanted more was to learn a defensive method similar to the God-Devil Suppressing Prison Body to protect himself.
He is kind to others and never provokes enemies, but for some reason, there are always people who bring him trouble. In this case, the best way is to take some precautions and detect the crisis in advance, so as to know yourself and the enemy and fight without danger.
So he wanted to combine his understanding of biomagnetic fields to establish a project to build a bioelectromagnetic field detection radar, in order to predict the enemy beforehand.
Although this plan is still under development, it is still far from success...
But Baili Qingfeng is a person with a simple heart and an open-minded temperament who loves learning. He can face success and failure calmly. As long as he can read more and learn more, he will always have a satisfied smile on his face.
