"I'm sorry, something happened in the morning."

"It's worthy of being a C-level mentor, and I don't even know a correct reason, I'm afraid I haven't even thought about the reason, right?"

What a bitter mockery.

Wu looked at the male student quite helplessly, he didn't pay attention to this male classmate yesterday, but if he looked at it carefully today, it seemed to be very ordinary.

The voice is slightly low, the speed of speech is slow and coherent, and the steady tone makes it difficult to feel the real emotion. With a pair of thick-rimmed glasses, the blue oblique bangs softly cover the right eye, but they can't hide the sense of exclusion from themselves.

This student seems to be a top student, because his desk is full of all kinds of books, all of which are difficult to understand.

But isn't that nonsense? This academy is Eliel's first choice, and if you want to talk about academic tyrants, every student in this academy is actually a scholar.

Although I didn't breathe all the way, I was a little irritable because of the sweat all over my body. Wu wiped the sweat from his forehead and asked curiously:

"Then that's the end of the greetings, I'll first ask if anyone knows the answer to the question I left yesterday?"

The moment the question was raised, the same male student immediately raised his hand, and his face showed impatience and pride.

Sure enough, it's him!

"Come on——, please speak."

The male student pushed the frame of the mirror rather arrogantly and stood up, and replied in a slow and methodical tone:

"First of all, I have to admit that you do have some ability, and I have to clap my hands for you to know magic that I don't know."

"Awards, awards."

He smiled shyly, responding to the male student's rude tone and words with a smiling expression.

This is really not what a student should say to a teacher. But I don't care about the student's attitude towards me, and in the face of such an arrogant and rude person, I don't care about it.

"So, tell me the name and full method of the magic I performed yesterday."

"Well, magic is achieved through the suggestion of a certain medium, and there are many such mediums, such as chanting, small movements, imagination and even relying on props. What you used on us yesterday was the 'silence technique' that is commonly used in military interrogations. This magic is not very difficult, it can be triggered by a certain medium at will, and you used the 'slap on the table' yesterday to activate this magic, I should be right? ”

This confident explanation made Wu nod in surprise, but his surprised expression did not change more.

The male student sat back in his seat with an arrogant look of affirmation, waiting for Wu to announce the final results.

However, Wu only smiled slightly, and did not immediately approve the male student's answer, but asked the other students present:

"Does anyone have any other answers?"

The class was silent, and it seemed that this should be the only answer.

Seeing that the answer was all, Wu couldn't help but show a slightly disappointed look.

However, this emotion was not obvious, or it was just a momentary emotional out-of-control, Wu regained a smile and looked at the male student, and asked curiously:

"What's your name?"

"Why should I tell a teacher who is leaving?"

"It's true that you don't need to tell a teacher who is leaving. Unfortunately, I didn't need to leave at all. ”

The male student immediately heard this sound, and he stood up in confusion and resentment, and slammed the table hard, and asked in a reprimanding voice:

"Why? Am I wrong? ”

"Uh-oh! You have perfectly interpreted the basic definition of magic and the understanding of 'silence', which shows that your passion and love for magic are unbiased in this answer. ”

"In that case, the reason for the wrong answer?"

"The reason is very simple, first of all, let me demonstrate what you called the 'silence technique'!"

As yesterday, Wu raised his right hand and gently slapped the tabletop, and the clear but quiet sound of slapping the table instantly spread to the entire huge classroom, and everyone present could hear it clearly.

The students began to try to speak, but as the definition of 'silence' says, after hearing the sound of slapping the table, they will be unconsciously implanted with the restraint of 'silence', and then they will not be able to make a sound.

The male student was not surprised to make a sound, and after confirming the situation, he still looked at Wu standing in front of the podium in confusion, shrugged his shoulders and asked him about his mistake.

However, the bright male student didn't notice a thing.

As a spellcaster, he himself also heard the sound of slapping the table, that is, he was also caught in the "silence technique" he cast, and he couldn't make a sound.

Wu responded to the male classmate's shock with an expression of "I can't help it", constantly moving his lips and teeth to try to talk to the male student, but because of the "silence technique", Wu also couldn't make a sound.

But this is completely different from yesterday's Wu, because when the whole class was banned, Wu was still able to maintain the state of voice.

Immediately afterwards, the male students also remembered that Wu was able to designate a few students who were not affected by the silence, and those who were not affected also heard the sound of slapping the table, but they were still unharmed.

The truth of the scary thinking caused the male student's eyes to widen and lose his previous arrogance. Instead, there was a lot of incomprehension and reluctance to be defeated.

Seeing the incredible expression of the male student, Wu also smiled slightly, and tapped the desktop again to lift the "silence technique".

"How? Do you know what you're doing wrong? ”

"What the hell have you done......?"

Although Wu won the gamble, there was no arrogance or smugness on his face, and he still maintained his usual indifference.

"The 'silence' explained by this male classmate is indeed a common magic used in military interrogations, but you don't seem to have figured it out. As a spell caster, if you don't wear a tool to block sound, you will be victimized. Other words! During interrogation, the interrogator who performs the 'silence' will also wear earmuffs to prevent the effects of the magic from extending to them. ”

As soon as the explanation was over, Wu walked up to the podium, picked up the chalk, and began to explain with images.

He first drew a simple "rabbit", although the outline and strokes are quite strange, but from the long ears and fleshy body, it is still barely recognizable as a rabbit.

It's so pretty! I drew the rabbit as if it were real, and it was engraved on this blackboard alive and vividly—

Some narcissistic people couldn't help but sigh that their painting skills were so exquisite, and they stayed on the podium to admire their paintings for nearly three seconds.

But soon, he pulls his narcissistic consciousness back into reality and asks the class:

"Ladies and gentlemen, may I ask what I am painting here?"

"Rabbit?"

"It's ugly, but it's supposed to be a rabbit, right?"

"yes, that's a rabbit, right?"

The sporadic voice began to answer Wu's question, perhaps he was also puzzled by the question just now, and in order to know the reason, he obediently answered Wu's question.

"What kind of skepticism is this, this is a rabbit! Really. ”

Disgusted, he wiped off the rabbit with his bare hands and continued to draw new images on the blurred chalk prints.

The second image is of an elephant with a long trunk.

In the same way, the "subtlety" of Wu's painting workmanship, if it were not for the symbolic long nose, I am afraid no one would have seen it.

"Okay, what kind of animal is this?"

"Elephants, huh?"

"It's not a human drawing, but you can barely tell it's an elephant."

"Well, it should be an elephant."

The answer was a little more enthusiastic than just now, but Wu still complained with disgust:

"Really, a bunch of imps who don't understand art."

After complaining, Wu wiped off the elephant with his bare hands and began to draw the next image.

This time, the painting has become a little better, and it is a mighty "tiger".

Before Wu asked any questions this time, the students replied directly:

"It's a tiger, right?"

"That's for sure. No matter how ugly you are, you shouldn't draw a tiger crookedly! ”

"This is indeed a tiger."

Wu nodded with satisfaction, it seems that this group of imps has also begun to understand the beauty of their own art.

As is customary, Wu once again erases the image of the tiger with his bare hands, and then begins to draw the next animal.

In this way, the order immediately after the tiger is "crane", "dog", "cat", and "bird", and the interaction between the students and Wu gradually warmed up, perhaps because of the weird but funny image, which melted the cold atmosphere, and then narrowed the interaction between Wu and the students.

However, when Wu painted the last animal, that is, the "centipede", the male student who had been silent for a long time couldn't help the anger in his heart, and slapped the table vigorously, breaking the atmosphere of harmony and happiness.

The sudden sound of slapping the table really frightened the other students, and the lively environment instantly returned to freezing, but Wu continued to draw the centipede on the blackboard without accident.

Glaring at the back of the serious painting, the male student angrily reprimanded:

"I don't want to see your ugly and deformed images, do you want to tell me the final answer?"

As soon as the words ended, the strange centipede was finished, and Wu threw the chalk back to the pen jar on the podium, clapping his hands casually, so as to pat off the chalk ash that had stuck to his gloves.

However, Wu did not plan to respond to the angry male student immediately, but set his eyes on the new class president he had appointed yesterday, Kayla.

"Come on! Kayla, please stand up and answer some of my questions. ”

"Uh-yes."

The slim figure was straight and straight, staring at Wu with a slightly nervous expression.

At this time, out of the corner of her eye, she noticed the pure white gloves worn by Kayla's hands, which seemed to be very similar to her own. Could it be that the amount of elemental in Kayla's body is also amazing?

Without thinking too much, Wu immediately looked away from the glove and refocused on Kayla's nervous expression.

“ＯＫ！ Excuse me, do you remember what was the first animal I painted? ”

The question wasn't very difficult, and an image of a funny-looking rabbit immediately came to Kayla's mind.

"Rabbit...... Is it? ”

"That's right! So let me ask you again, what's next? ”

Kayla hesitated, but after a moment of thought, she barely remembered.

"Elephants, huh?"

"Oh!? With such a good memory, let me ask one last question, what is the fifth animal I painted? ”

"This ......"

Kayla couldn't answer for a moment, but in fact, not only Kayla, but even the other students in the audience looked at each other and tried to think.

Then there was a lively discussion in the classroom, and all kinds of animals that had been painted by Wu were mentioned, and even animals that had not been painted at all were mentioned.

Seeing that Kayla couldn't answer, Wu asked everyone present:

"Does anyone remember?"

Everyone fell silent, and it seemed that no one remembered.

With a triumphant smile, he propped his hands on the podium, chuckled and explained:

"To be honest, I actually forgot."

"What!?"

The class shouted in unison.

"Ahahahaha, who remembers drawing so many animals! However——, do you know that when people's minds are constantly exposed to new images or sounds, they will gradually overwrite the old images or sounds that they touched at the beginning, and if you don't review them, you may forget them forever. So, that's the answer I want to say to this male student. ”

At this time, Wu finally turned his eyes to the face of the angry male student on the side, and continued to explain with a relaxed and comfortable expression:

"This male classmate is right, I did use the 'silence technique' on you yesterday. However, the medium used to activate this magic is not the 'sound of the table', but the 'snap of the fingers' that first disarm the 'bondage magic'. ”

"Flick your fingers?"

Faced with the unanimous questions of all the students again, Wu nodded seriously and continued to explain:

"Yesterday I used my own elements to forcibly break through the 'binding magic' you created, but to be honest, you don't need to do anything to break through the magic array, so you should understand, right?"

Speaking of which, the male student could not hide his previous arrogant anger, revealing a rare "horror", which seemed to be a formal understanding of Wu's scheming.

Wu smiled and admired the horror of the male student with considerable satisfaction, although it is not a happy thing to win against a small child, but it feels good to be able to thwart the spirit of such an arrogant little child.

At this time, Eve, who was sitting in the last row, raised her hand, attracting Wu's attention.

"Come, Eve, please."

"Yes, that is to say, teacher, you actually performed the 'silence technique' yesterday before class, did you guess that the students would disobey you?"

After a guess, Wu raised her eyebrows and smiled more satisfied, "Eve got it right", but then Wu's expression changed to a "You answered wrong" look.

"Eve-san is right, but it's a little wrong."

This answer raised questions again.

"I say this precisely because you have all overlooked one important factor. The so-called 'silence technique' is not as easy as you think. The reason for the inconvenience is precisely because this magic requires a pre-assignment, which the male student did not mention. You have to unconsciously imply an action to the target, and the target is unaware of the intent of the action to be successful, and this action is the command to activate the 'silence' later. Yesterday, in the name of lifting the 'bondage magic', I let you see the 'snap of your fingers' without your awareness of defense, and this also successfully completed the pre-work of the 'silence technique'. ”

Ignoring the admiring stunned gazes of the students, the gushing Wu continued to explain:

"Also, in fact, the interrogators of the military do not often use the 'silence technique', but instead use the 'silence magic device' that does not require pre-work. It is precisely because of the widespread use of the 'silence technique' that many criminals have begun to seek ways to crack it, which has also indirectly increased the difficulty of interrogation. ”

Wu is quite devoted to the work of imparting knowledge, although it is not out of the original intention, but the joy of sharing knowledge seems to make him forget the purpose of the task, this inexplicable emotion is completely unaffected by gluttony, and reflects the purest self in the heart.

The rebellious self used to be a lover of reading, and he didn't even want to mention the slightest knowledge about magic. Now that I can educate these excellent students as mentors, I honestly say that this novelty has become the most important pleasure besides fighting.

After explaining the same thing, Wu then turned his attention to the male classmate again. With a disapproving smile, he admired the angry look on his face.

"To be honest——, I don't need to slap the table instead of snapping my fingers, after all, you're all so focused on the surprise that the binding magic was cracked, and you didn't guess that I was going to use the silence spell. However, I was still worried that some of the 'smarter' people would see my trick, so I will draw your attention to it with a noticeable slap on the table, so as to make you forget the flick of your fingers at the beginning. I really can't help it, who told you to be the best class in the second grade? ”

It seems to be explaining to the class, but there is something in the words.

That's right, in fact, the sound of slapping the table yesterday was quite subtle, and in the noisy environment where everyone opened their throats and scolded, it was absolutely impossible for that kind of slapping sound to reach everyone's ears.

But for the relatively "careful" elite, such a keen heart hurts themselves.

He was the only one who observed his subtle movements, and from the moment I entered the classroom, he began to observe himself intently, and he was quite insightful.

It's a pity that in the end, being smart was mistaken by being smart, and this gamble was won by himself.

Wu stretched out his hands and motioned for Kayla and the male classmate to sit back in their seats, and Kayla only smiled sweetly in response, but the arrogant male student still couldn't accept his mistake, clenched his fists and glared at Wu with a fierce face, and slowly sat back in his seat.

Before the students came out of the answers full of twists, Wu Xiao, who was about to open the textbook, let out a fake smile and said excitedly:

"Since it's no problem, I'll lead you until graduation without any surprise, and I hope you can get along well——!"

At this time, the corner of Wu's curved eyes glanced at the back of the book he was carrying, and the title of the book marked on it couldn't help but keep him smiling calmly but in a cold sweat.

This class is a purely theoretical "monster science", and the textbook I carry is a practical "monster anatomy".
