Stability group.

The storm in the group has not subsided because of the death of Eddie father and son. After all, Eddie father and son is only one of the leaders and does not represent the whole of the stability group. Now ... but with the arrival of 3 His Highness the Prince, The stability maintenance team is operating at a high speed, and it seems that there is a major move in preparation.

"Mr. Yabo, this is the person who has information and contact with the team leader before the killing of Eddie."

Another leader of the group, Andrei, passed the information to Yabo.

Eddie Father and son has been dead for several months, but in the past few months they haven't disappeared, but just changed their direction slightly.

"At present, the most active people in Xia are the Aurora and Chiyan people. In addition, the people of the glorious empire are not dead, and they are stirring the wind and rain in Xia ..."

Looking at the information, expression was a bit indifferent.

"The strength of the Glorious Empire is rapidly declining with the advent of the new era, but it still has a decisive influence in the World. In addition, our Shia has been governed by the Glorious Empire for more than a decade. Even if they were expelled by us now, After all, there are too many of us in the back of Shia ... "

Andre said.

"The times are different."

Calmly said: "The glorious empire relied on giant ships and cannons to run the world. The old days are gone. The future is in the hands of martial artists. Whoever has enough Holy Land and resources will be able to find new ones that have arrived. Dominate the World in this era! "

"Martial artist ..."

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

Even if it is as strong as a War Grade martial artist, it is equivalent to an enhanced tank. The real national strength and the outcome of a war are still comprehensive military and economic strength.

"en! ?"

At this time, Yabo who looked through the information seemed to see: "Baili Changkong?"

While speaking, he carefully looked at this information: "It is really Baili Changkong that is half-disciple of Equivalent to Moore this General. Eddie took him as his object to pull the lurking forces of Moore this General lineage. Come here and help him to charge in Xia Haizhou ... plot against is good, but as far as I know, the group of people is hiding deeply and the power is not weak, and it is not easy for Eddie to dig them out. "

"We have investigated this Baili Changkong, and when Leader Ed was killed, he was not in the city of Xia."

Andrei added the last sentence: "Mr. Yabo thinks this person is suspicious? So he is also included in the key investigation?"

"Even if he has proof of his presence, this group of people is not small, let alone me, 3 His Highness the Prince is not willing to provoke easily."

Yabo said, exposing the matter.

"In fact, there are people in this group ... the day when Mr. Eddie died, he specially asked his assistant to edit a profile, a profile involving the Aurora Empire."

Andrei said to extract another piece of information.

Abo glanced aside: "I suspect that the people of Baili Changkong killed Russell? How could it be, this guy from Eddie seems to want to murder a person with a borrowed knife."

For a moment, he seemed to think of something again, took the document up again, and carefully looked at it for a moment, thinking: "Mer this General lineage is not a small force lurking, if it can really draw to His Highness's camp ..."

It took a while before he handed this information to Andrei: "Copy a copy and find someone to send it anonymously to the Aurora ambassador to the Rafi military ambassador."

"Yes."

……

Shire University.

Professor Zhou Tianwen from the Department of Physics is explaining sound knowledge.

"There is relative movement between the vibration source and the person, causing the frequency of the sound to be heard to change, which causes the tone to change, just like the whistle of a train or a car, the tone of which changes from far to near and near to far, This phenomenon is called the Doppler effect. "

"The Doppler effect can be used for diagnosis. When examining the blood flow rate, it can be achieved by transmitting an ultrasonic vibration source. The Doppler effect is generated between the vibration source and the relatively moving blood. Blood vessels move against the ultrasonic source, and the wavelength of the reflected wave is Compression, frequency increases, the wavelength of reflected waves increases when blood vessels leave the sound source, the frequency decreases, and the increase or decrease of reflected wave frequency is directly proportional to blood flow velocity. This principle is also used for speed measurement. "

"The traffic police sends ultrasonic waves with a known frequency to the moving vehicle while measuring the frequency of the reflected wave. The speed of the vehicle can be calculated based on the frequency change of the reflected wave. Apart from this, this effect can also be applied to other similar waves. , 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.

One lesson passed unconsciously soon.

The professor at Shier University always left after finishing the class. At the moment, Baili Qingfeng rushed to catch up: "Professor Zhou, I would like to ask you about the connection between ultrasound, infrasound and resonance."

"Oh, the principle of ultrasound, infrasound, and resonance is very simple. Buy an air humidifier. The air humidifier is to use the violent vibration of the ultrasonic wave to break up the water flow, make the water flow into small droplets, and then blow it into the room with a fan ..."

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

Baili Qingfeng said: "We humans have invented radar, sonar, and ultrasonic inspection instruments by observing bats, and can even use ultrasound to break within the body stones. Then, is it possible for humans to evolve their own understanding of ultrasound and infrasound through evolution? Hold ... "

"The core of your problem is not sound waves, but the evolution of organs. The ability of humans to accept sounds is only 20 to 2 10000 Hz, and frequencies outside this range are called infrasound waves and ultrasound. If you really want to evolve a bat general ultrasound Ability, you must first solve the information processing ability of your brain. This problem solves the next thing. It is easy to handle, but the question is, can the human brain calculate that many sound wave frequency changes in such a short time. "

The professor laughed and felt Baili Qingfeng was whimsical.

There is no need to answer such questions.

"Unless the brain has a filter-like function?"

"Yes, the emission of waves is not a problem. The key lies in receiving, filtering, encoding, and parsing."

Professor nodded: "The course just said that when we emit sound waves and electromagnetic waves that encounter other objects, they will cause fluctuations. The change in frequency can determine how fast the object is. The time from the time the wave is transmitted to the time when the wave is received can be calculated as long as After extracting this frequency change, you can easily measure distance and speed, and make a radar. If you are really interested in this area, prepare microwave signal sources, power dividers, transceiver antennas, high-frequency amplifiers, and mixers. , Filters, low-frequency amplifiers, and signal conversion modules to try for yourself. "

"I'll try it when I go back."

Baili Qingfeng said.

Professor nodded: "If you don't understand anything, you can ask me again, of course, it is limited to physics knowledge."

After the professor left, Baili Qingfeng quickly ran to the electronics market and searched for related instruments.

Thunder Dominator's idea is Sixth Layer Divine Transformation. He can barely control his lifeform electric field. Since then, he has wanted to develop a set of acoustic arts, which can be used to deal with enemies in a range.

After all, he is a hobby peaceful, kind and upright person.

The attacking secret method is too strong for his original intention. He hopes to learn a defense method similar to Demon Hell Suppressing Physique to protect himself.

He is good to others and never provokes the enemy, but I do n’t know why, but someone always causes him trouble. In this case, the best way is to do some prevention and detect the crisis in advance, so as to know yourself and know your enemy , and you will never be defeated.

So he wanted to combine his understanding of lifeform's magnetic field to build a project to make lifeform's electromagnetic field detection radar in order to meet enemy prophets.

Although this plan is currently under construction, it is far from successful ...

But Baili Qingfeng is a simple and open-minded person who loves to learn. He can face successes and failures calmly. As long as he can read more and learn more, he can always have a satisfying smile on his face.
