The laboratory of Neil Mazar, the faceless mask on the fifty-sixth floor of Hesso Tower.

A biological specimen called Dora polyphonic bat was soaked in a solution container and placed in front of Green. There was also a huge leather scroll on the test bench, which recorded the knowledge of Dora polyphonic bat's auditory perception system.

"In the sound world, it is not as monotonous as ordinary human beings perceive it. The superficial level of sound is divided into infrasound, ordinary sound, and ultrasonic, and the middle level is divided into pitch, audio frequency, timbre, sound shape, sound quality, and rhythm. There are even voices of the soul, the voice of the earth, the voice of the world, the voice of mystery, the voice of spiritual perception, the voice of resonance, the voice of thinking, the voice of doom, the voice of power, the voice of instinct, the voice of paralysis, the voice of phantom Voice..." Neil Mazar explained the most basic knowledge of sound science in a dull and dry manner.

(Pseudoscience, don't bring it in with real knowledge.)

Neil Mazar pointed to a human hearing nerve analysis chart, and said lightly: "The sound frequency that ordinary humans can perceive is between the 29th string and the 20090th string. The wizard named the sound of this frequency as the normal sound. And the sound lower than this frequency The wizard named the sound of infrasound, and the sound above this frequency was named ultrasonic."

Green has only been exposed to some of the simplest and basic knowledge of sound waves. At this time, listening to Neil Mazar's lukewarm explanation of knowledge, he is quickly recording relevant knowledge in the handbook.

Picking up the scroll, Neil Mazar pointed to the ear of Doradobat and said, "Have you seen the auditory nervous system in this area? In the early years, I studied sound witchcraft under the guidance of my mentor, and I was obsessed with this ultrasonic witchcraft." Perception and infrasonic resonance are destroyed, and the ultrasonic positioning witchcraft of the mask is the refining that I completed under the guidance of my mentor."

Green thought for a while, and didn't care about Neil Mazar's unfriendly attitude deep in his heart. Asked: "Why don't adults carry out this kind of transformation on the human body, but choose to refine the mask?"

Neil Mazar mockingly "looked at" Green and sneered: "Hmph. Don't use your cognition to bring into my thinking. You may be proficient in human life sciences, or your instinctive cognition is self-transforming evolution. But At that time, after studying alchemy and sonic witchcraft day and night, my first reaction was to make a second-cognition magic tool, and I never thought about body modification at all."

Green suddenly realized.

Indeed, just a moment ago, Green made a mistake in thinking. He took it for granted that other people should think the same as himself, and he should carry out human body modification on himself to achieve a certain degree of active evolution of some organs.

However, this seemingly "evolution" of ordinary people. Isn't it a kind of degeneration?

He can hear ultrasound, but not normal sound. Although it will bring convenience to wizards at certain times, it is a lot of trouble in daily life.

After all, in the wizarding world, wizards are still accustomed to language communication rather than soul communication.

From this point of view, it is indeed a wise choice to refine a mask that can choose to turn off special functions at any time.

Neil Mazar pointed to the protruding sharp corner on the mask, and said lightly: "This thing uses the special hearing of the Dora multisonic bat to receive ultrasonic waves. Then I use the rune positioning technology that I have studied for seven years. Conduction forms a kind of soul perception of the sound world and body. So in the next half month, you will mainly learn these rune positioning technology conduction, this is my core knowledge of ultrasonic positioning witchcraft."

Green quickly drew an auditory map of Dora polyphonic bat on the notebook. Then he put away the Letters and followed Nierma into another laboratory.

It has to be said that Neil Mazar's imparting of knowledge like this is simply teaching Green to refine the pale mask.

Moreover, the indifferent attitude and condescending psychological rejection. It also made Green understand that he wanted to gain knowledge from other wizards. This is such a difficult thing. After all, knowledge can indeed be purchased with other finances. But for wizards, the value of knowledge is always higher than finances, so there is a natural sense of rejection.

The reason for this feeling of repulsion is as if some incompetent guy relied on wealth to forcibly exchange his most precious treasure.

As for Green, it is impossible to obtain a deeper level of sound wave knowledge through such a knowledge explanation!

Of course, Green will not delve too deeply into the knowledge of sound waves. Green's way forward is a combination of traditional elemental knowledge and body self-evolution, using his "talent" to explore advanced elemental knowledge that is easier to study, so he has no idea about deep-level sonic witchcraft.

Want to become an omniscient wizard?

If you study everything, because the energy and cognition of wizards are limited, wizards who study comprehensively will only develop into stupid wizards who don't know anything.

It is as if a wizard who leverages ten times the leverage of all ten elements can never be an opponent of a wizard who leverages a hundred times the leverage of one element. (The analogy is a bit exaggerated, but the general meaning is like this.)

With regard to the knowledge of sonic science, Green can only write down the knowledge taught by Neil Mazar like a blood horror doll of occultism.

In this way, there is no difference in the attitude of other weak wizard apprentices learning witchcraft.

For those weak wizard apprentices, they just do whatever is in the magic and witchcraft books, and they don't care about the shallow basic knowledge reasoning and deep knowledge associations, and they don't have any opinions of their own.

They have nothing, just to let themselves get the power of this witchcraft, and then go to learn the next witchcraft.

Because in their eyes, this is a powerful force.

...

Half a month later.

Green has initially mastered the knowledge of rune positioning technology transmission. This is also the first time that Green has seen that the wizarding world does not use a big circle with six stars as the basis of the magic circle, but presents a spiral pattern.

Neil Mazar seemed to be a traveler in a hurry, and then began to introduce the "pseudo-wizard hood" permanent maintenance technology to Green. This kind of overloaded learning made Green feel a little bit big-headed, and once again experienced the hard work of seeking knowledge.

No one selflessly imparts any knowledge of witchcraft to anyone other than a mentor. Because all wizards know the hardships of gaining knowledge, they are selfish.

And when wizards selfishly hide their knowledge. Knowledge will be harder to come by...

Wizard hood and cursing will be compulsory courses for all witch hunt wizards.

Unlike internal battles between wizards. When fighting in the foreign world, due to the existence of the original space fortress, the all-round defense of the wizard hood will be the most basic and perfect defense for the witcher wizard to fight against the creatures of the foreign world. This defensive measure is a wonderful witchcraft that was born based entirely on the original space fortress. It is a great witchcraft that equalizes the creatures of the foreign world and obtains the shelter of the local world after the wizard's original space fortress invades the foreign world.

As for the curse, the curse and witchcraft in the wizarding world seem to be of little significance. With the companion worms, the wizard has a strong anti-curse characteristic, unless it is those who have prepared for a long time for large-scale curses and wizards who specialize in curse witchcraft. It can also achieve the purpose of cursing to death.

But in the foreign world, ordinary creatures can only rely on the world's protection and avatar characteristics and physical strength to resist the wizard's curse. In this case, as long as the witcher wizard obtains some physical information of creatures from other worlds, it will be the beginning of a nightmare for those creatures from other worlds.

Therefore, almost every mature witch hunt wizard has in-depth research on wizard hood and curse.

The so-called wizard's hood on the pale mask is not a real wizard's hood in the strict sense of witchcraft. Because it cannot increase in strength as the caster's strength increases.

This "wizard hood" is just a constant repulsive energy body imitating the refining of the witchcraft hood, and it has carried out specialized resistance refining for conventional elemental resistance.

(It seems that Green's conventional element resistance passively evolves, which seems to be comprehensively strengthened, but if it encounters an unconventional element, all resistance will lose its effectiveness.)

Another half month later.

After Green finished learning the so-called wizard hood constant maintenance knowledge, he felt deeply deceived.

There is no wizard hood, only comprehensive class-resistant witchcraft, and the only thing that makes sense is the constant maintenance system. There is a little creativity, maybe Green will use it in the future.

The full expectation finally turned into disappointment, but Green could only sigh.

Want to gain knowledge by tricky means?

too difficult……

Knowledge. Sure enough, only what you get is the best, and others will never be able to truly impart their knowledge to you selflessly. From this point of view. It also reflects the role of mentors and the deep meaning of regional college wars.

In order to obtain witch spirits or other benefits, esoteric wizards have to pass on their knowledge to their disciples. To strengthen their strength to compete for certain interests, and thus invisibly add new blood and future hope to the wizarding world. Even for some wizard apprentices with relatively good qualifications and excellent performance, there will be behaviors where wizards compete to pass on their knowledge.

How many wizards would do such a boring thing if they were not motivated by profit?

Legacy of the Wizarding World? The future of the wizarding world? Hope for the wizarding world?

Not all wizards will consider these things. For ordinary, normal, and low-level wizards, it is fundamental to strive to achieve a higher level of strength.

…………

Three days later, at the window of the Per Anos laboratory on the seventy-ninth floor of Hesso Tower.

Looking down at the entire Hessota Wizarding Academy, Green felt a little lost and sad.

Peleanos glanced at Green, and said in a low voice: "Aren't you really going to see your friends? Especially your little lover, Lafite, who dragged her mentor over to ask about your situation." , I dealt with it."

Under the pale mask, there was a trace of determination in the depths of Green's eyes that could not be concealed. He shook his head and said lightly: "Let us all stay in the good memory of that night."

Peranos said in a deep voice: "You have to think about it. Once you leave, you will have to improve your mental power for a long time after you have been promoted to an official wizard, and there is also a foreign battle for the preparation of the witcher to become an official witcher." , It will take at least two or three hundred years to come back again. At that time, except for those few of your friends who have advanced to official wizards, others will really become your eternal memory."

Green gritted his teeth, trying not to show any weakness in his eyes.

Looking at Pele Anos, Green said firmly: "There is no need to say more about the mentor. If they have not been promoted to official wizards, let my memory stay in the beauty of that night forever. Take a look or two more , what's the use?"

Peranos shook his head and sighed: "Let's go, every official wizard must go through this kind of thing, no one can avoid it. After these two or three hundred years have passed, you will become a real wizard. In the meantime, you are just a wizard apprentice with the power of a wizard."

"understood."

Green followed Per Anos into two black dots in the sky and left the Hessota Wizarding Academy.
