The Unkillable Swordsman

Stability Team.

The turmoil in the group did not subside because of the death of Eddie and his son. After all, Eddie and his son are only one of the persons in charge, and they do not represent the entire stability maintenance team. Big moves are underway.

Mr. Yabo, here are the information and contacts about the investigation before Team Leader Eddie was killed.

Andre, another person in charge of the team, handed the materials to Ya Ya.

It had been several months since Eddie and his son had died, but they hadn't disappeared and accomplished nothing in these months, but they had just changed directions slightly.

Currently the Aurora people and Chiyan people are the ones who are most active in Xia Ya. In addition... people from the Glorious Empire are still not giving up, stirring up wind and rain among Xia Ya...

Ya Ya looked at the information and looked a little indifferent.

The power of the Glory Empire has declined rapidly with the arrival of the new era, but it still has a decisive influence in the world. In addition, we Xiya has been ruled by the Glory Empire more than ten years ago, even if they are expelled by us now, but After all, there are too many behind us in Shia...

Andre said.

Times are different.

Ya Ya calmly said: The old era of the Glorious Empire relying on giant ships and cannons to run rampant around the world is gone forever. The future is in the hands of warriors. Whoever has enough holy places and resources will be able to survive in the new era that has come. Dominate the world!

Musha……

Andre's level is not high enough, and some people can't understand the true meaning of Ya Ya's words.

Even if it is as strong as a war-level fighter, it is equivalent to a reinforced tank. The real national strength and the outcome of a war are still comprehensive military strength and economic strength.

Um!?

At this moment, Yabo, who was flipping through the information, seemed to see something: A long sky?

While talking, he looked carefully at the information: It's really equivalent to the half-disciple of General Melbourne's Bailichangkong. Eddie took him as the target to win over the hidden forces of General Melbourne's lineage. Helping him lead the charge in Xiahai Prefecture...the calculation is not bad, but as far as I know, those people are hiding very deep, and their power is not weak, it will not be easy for Eddie to dig them out.

We have investigated this Bailichangkong. Team leader Eddie was not in Char City when he was killed.

Andre said, and added a sentence at the end: Mr. Yabo thinks this person is suspicious? Then include him in the scope of key investigation?

It doesn't matter if he has an alibi, this group of people is quite powerful, let alone me, His Royal Highness the Third Prince is not willing to provoke easily.

As Yabo said, he revealed the matter.

Actually, there is something about this group of people... On the day Mr. Eddie died, he specially asked his assistant to edit a document, a document involving matters related to the Aurora Empire.

Andre said and pulled out another file.

Ya Ya glanced at it and put it aside: The person who suspects Baili Changkong killed Russell? How is it possible, Eddie seems to want to borrow a knife to kill someone.

For a moment, he seemed to think of something again, picked up the document again, read it carefully for a while and thought: The power of General Melbourne's lurking line is not small, if we can really win over His Highness's camp...

After a while, he handed this document to Andre: Make a copy, and find someone to send it anonymously to Military Attaché Lafite at 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 a relative movement 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 a train or a car whistle, and the pitch changes obviously from far to near and from near to far. This phenomenon is called the Doppler effect.

The Doppler effect can be used for diagnosis. When checking the blood flow velocity, it can be realized by emitting an ultrasonic vibration source. The Doppler effect is generated between the vibration source and the relatively moving blood. The blood vessel moves against the ultrasonic source, and the wavelength of the reflected wave is compressed. , the frequency increases, the wavelength of the reflected wave increases when the blood vessel leaves the sound source, and the frequency decreases, and the increase or decrease of the frequency of the reflected wave is proportional to the blood flow velocity, and this principle is also used for speed measurement.

The traffic police emit ultrasonic waves with a known frequency to the moving vehicle and measure the frequency of the reflected wave at the same time. According to the frequency change 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 surface, 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 took notes patiently.

A class passed quickly without knowing it.

The professors at Shire University always leave immediately after class, and Baili Qingfeng hurriedly chased after him: Professor Zhou, I would like to ask you about the relationship between ultrasound, infrasound and resonance.

Oh, the principle of ultrasonic wave, infrasonic wave 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, making the water flow form small mist, and then blow it into the room with a fan...

I want to understand the relationship between sound waves, electromagnetic waves, and biological waves.

Baili Qingfeng said: We humans have invented radar, sonar, and ultrasonic inspection equipment by observing bats, and can even use ultrasonic waves to shatter stones in the body. So, is it possible for human beings to enhance their own understanding of ultrasonic waves, infrasonic waves and Storage...

The core of your question is not sound waves, but organ evolution. Human beings' ability to accept sound is only 20 to 20,000 Hz, and frequencies beyond this range are called infrasound waves and ultrasonic waves. If you really want to evolve bats Ultrasonic ability, you must first solve the information processing ability of your brain, this problem is solved, the next thing is easy to handle, but the question is, can the human brain calculate so many changes in the frequency of sound waves in such a short time? .”

The professor smiled, feeling that 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 a problem, the key lies in receiving, filtering, encoding, and analyzing.

The professor nodded: The course just said that 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 emission to reception can be used to calculate the distance. , as long as this frequency change is extracted, you can easily measure distance and speed, and make a radar. If you are really interested in this aspect, prepare microwave signal sources, power splitters, transceiver antennas, high-frequency amplifiers, and mixers. Frequency converter, filter, low frequency amplifier, signal conversion module to try it yourself.”

I'll try it when I get back.

Baili Qingfeng said.

The professor nodded: If there is anything you don't understand, you can ask me again. Of course, it is limited to the knowledge of physics.

After the professor left, Baili Qingfeng quickly ran to the electronic market to search for related instruments.

From the idea of ​​thunder dominance to the sixth level of supernatural transformation, he can barely control his own bioelectric field. Since then, he has thought about developing a set of sonic martial arts, using sonic resonance to deal with enemies in a wide range.

But after all, he is a peace-loving, kind and upright person.

It was not his original intention to attack the secret method too violently. What he hoped more was to learn the defensive method similar to the gods and demons to suppress the prison body to protect himself.

He is kind to others and never provokes enemies, but for some reason, someone always brings him trouble. In this case, the best way is to take some precautions and detect crises in advance, so as to know yourself and the enemy and win a hundred battles.

So he wanted to combine his own understanding of the biomagnetic field to establish a project to manufacture a bioelectromagnetic field detection radar, in order to predict the enemy.

Although this plan is still under approval, it is still far away from success...

But Baili Qingfeng is a person with a pure heart, open-minded temperament and love of learning. He can face success and failure calmly. As long as he can read more books and learn more things, he can always have a satisfied smile on his face.
