Now Leo, Anna, and Mason's bodies are developing rapidly, and their proportions are gradually harmonizing. They are now in the same school as Xiaolan and the others, but they are in junior high school, and Xiaolan and they are already in high school.

Leo has changed a lot, not only has his body grown a lot taller, but he has also become stronger, he is the best of the eight people except for Robert. But he was still very dissatisfied with his body, because what he wanted to do, he couldn't do now.

When we first took action three years ago, everyone's intercom equipment was very inconvenient and easy to be discovered. He was wondering if since they could hear the sound that ordinary people couldn't hear, if they only needed to make sounds lower or higher than this range, only they could hear them, and ordinary people couldn't hear it, wouldn't it mean that they had intercom equipment that they didn't need other equipment.

The frequency of the sound that the average person can hear is between 20 and 20,000 Hz, and the sound below 20 Hz or more than 20,000 Hz is inaudible. But Leo can, they pass the hearing test, they can hear sounds from 6 Hz to 50,000 Hz, and they are very good at distinguishing sounds. The sound with audio below 20 hertz is called infrasound, and the penetration ability of the sound is very strong, so if he can emit infrasound, he can do that only they can hear the sound that others can't hear, this is the best intercom equipment, and he is not afraid of others eavesdropping at all.

Leo knew that when a normal person makes a sound, he first inhales air, then adducts his vocal cords, tightens, and temporarily holds his breath. The air exhaled from the lungs impulsively vibrates the vocal cords that move closer together, and this vibration also causes the air in the larynx to vibrate together to produce sound.

He knew that to be able to emit infrasound, he needed to control not only the speed of the airflow out, but also the frequency of the vibrations of the vocal cords. In order to exercise his control of the vocal cords, he first practiced speaking, imitating the people around him, and his imitation was not only the same tone and intonation as the person being imitated, but also the same voice as the person being imitated.

From the time he started practicing, he basically didn't speak in front of people, he had to listen carefully to how the larynx worked when other people spoke, and when he had a basic understanding, he used his own larynx to imitate.

When he imitated Anna's voice in front of Mason for the first time, Mason was shocked, and he looked at Leo incredulously, not understanding how he did it. Then he asked Leo to teach him.

Leo pulled him to find everyone, and told everyone about his desire to send out infrasound, when everyone heard his thoughts, the first thing was that Leo had an unexpected idea coming out, and the second was that everyone didn't know how to send infrasound, and they didn't know if they could send it.

When Leo explained the structure and working of the human larynx in the same voice as Anna, everyone was as shocked as Mason. At that time, Anna also asked Leo why he imitated her voice first, whether it was because she had the best voice. Leo's answer was as if Anna ran after him all over the house, and his answer was: "No, it's because you're the only one who always chatters in front of me all day long, and I can't listen to it, so it's easiest to imitate." ”

From that day on, everyone also followed Leo to learn to control the laryngeal cavity, first imitating the people around him to speak. When everyone is able to speak in other people's voices, they often speak in one person's voice when they talk together, such as eight Gabi talking at the same time, or eight Gibsons talking.

Everyone knew that even if they couldn't emit infrasound to the way Leo thought, it was remarkable to have the ability to imitate other people's speech.

When Leo was able to imitate any speech he heard, he began to experiment with infrasound waves, and now he has practiced emitting strong air currents through his lungs and reducing the frequency of sound when passing through the laryngeal cavity to achieve the effect of emitting infrasound waves.

It's just that now he has encountered greater difficulties, although he can emit infrasound, but now the infrasound is only a frequency, even if he hears it, he doesn't know what he is saying, only after emitting infrasound waves of different frequencies, people who hear him speak will know what he is saying.

It may be that his brain is not active enough to effectively control the muscles of his mouth and throat, so Leo knows that this is not in a hurry, maybe he should be able to grow up a little more.

The three of them had just started school, and they caused quite a stir in the school, unlike Xiaolan, who tried to keep a low profile when they went to school so as not to be noticed and cause unnecessary trouble.

And Leo is different, now they have a firm foothold in Miami City, as long as it doesn't cause too much sensation, others will only treat them as ordinary geniuses, and will not treat them like aliens.

Therefore, the three of them are very high-profile at school, especially Anna and Leo, they are originally showy personalities, and they won't be able to keep a low profile if they want to, so it's better to let them do it. Robert's father told them, "Now in Miami, as long as you don't make trouble, everything else can be settled," and Anna and Leo were even more emboldened.

It's been more than two months since the start of school, and Anna and Leo have completely lost interest in school, and they spend every day peacefully, always thinking that something can happen.

On this day, when someone saw Anna's bezeprising face and figure, a certain boy whistled in front of her in order to get Anna's attention.

Leo looked at the boy's eyes and the gazes of the people around him, and he knew that something interesting was finally going to happen. So without saying a word, he went up and gave the man a big mouth. But he didn't grasp his strength well at that time, and he used too much force, and the big teeth of the person he hit fell out of two teeth, and the mouth of the person who made it was full of blood.

The boy in the middle school was a troublemaker in his own right at school, and when he saw that he was beaten, several of his brothers also stood up together to get an explanation from Leo and them.

Leo and Anna saw that more than a dozen of them had already stood up, as if they were going to fight, and the two of them, who had never suffered a loss, were in line with the principle of attacking first and suffering later. Immediately stepped forward to greet a few people, their kung fu is not ordinarily strong, even the SWAT officers alone are not their opponents, this is still the case that they don't want to show too much strength, if they go all out, one of them can sweep the entire SWAT team of 13 people.

In just a few breaths, the man who had just whistled and his dozen brothers were lying on the ground making a "hum, hum" sound, unable to get up. Leo and Anna are still measured, don't look at the fact that they can't get up now, but they are all skin injuries, although they are painful, they will not have sequelae.

Soon the school sent someone to call them all to the principal's office, and when the principal asked why, it was also a headache. The principal knew that both sides had a certain background, so in the spirit of turning big things into small things and small things into small things, he just warned both sides that they were not allowed to fight in the school next time, and let them go back.

As soon as he left the principal's office, among the few people who were beaten, he said to Leo and Anna in a provocative tone: "There is a kind, after school, find a place to settle this matter, don't run away in advance."

Leo and Anna glanced at each other, and they both saw the smile in each other's eyes, and Leo said indifferently: "As long as you are not afraid of being beaten again, as long as you dare to come, we will dare to beat you again!"

The man gritted his teeth and uttered a good word, and then he left in anger.

When Anna and Leo left the school gate after school that day, they saw that many young people in alternative clothes had gathered outside the school, and they also had wooden sticks and iron rods and other weapons in their hands.

They told Mason to wait a moment and go back with Xiaolan and them, they were going to the event. Mason looked at the group of young people outside the school with pity, and told Leo and Anna: "Don't take it too seriously, just teach them a lesson."

Anna said nonchalantly, "Ah, we have measure, go Leo, don't make people wait." ”

Leo and Anna came to the group of young men together, and saw that the student who had been beaten in the mouth by Leo today was also among them, and he saw Leo coming over. opened his mouth and said: "You still have some backbone, you didn't run away, come with us, I know a place where no one is, let's end it!"

So Leo and Anna followed them to the bottom of a viaduct, which was really quiet and there were few pedestrians, and it was indeed suitable for fighting.

Leo smiled and said, "What are you going to do? Or we give you a request, and if you can do it, it's over. How?"

"Fart, you're daydreaming. We will also give you an explanation, and we have to listen to your request, are you doing the opposite, now there are many of us, you have to do what we ask you to do. One of the youngsters dressed in alternative clothes spoke.

Leo smiled even more happily at his unkind gaze, and then said, "Oh, can you have the final say if you have a lot of people? But although there are many of you, you are all scaresome." ”

"Hmph, if it's to scare you, you'll know in a moment. The young man said that he was clearly the leader of the group.

Anna said in a disdainful voice: "Don't think that if there are too many people, you should hurry up if you want to fight, we will have to go home for dinner later." ”

This group of young people couldn't hold back anymore when they heard Anna's words, and rushed towards Leo and Anna with the weapons in their hands.

Leo was just about to rush out, but was grabbed by Anna beside him, only to hear Anna's voice coming: "You help me suppress the formation, I can deal with them by myself." Leo couldn't bear to spoil her excitement when he saw her excitement, so he could only shrug his shoulders and stand in place.

Anna's expression became serious in an instant, her every movement was natural and smooth, without dragging her feet, no matter what the other party wanted to attack her, she could always hit the other party before the other party touched her. And the people who had been attacked by Anna couldn't attack her anymore, because they were already lying on the ground, holding on to the position attacked by Anna with their hands and moaning uncontrollably.

The battle was soon over, and when Anna returned to Leo, there was already a patch on the ground, and Anna turned around and smiled sweetly at them. It was like a nightmare for them that they saw Anna's smile and their eyes changed, as if they had seen a demon smiling.

Now they understood that Leo was not talking in a dream, but really thinking about how to end the matter. The guy who can still talk is the guy who was beaten by Leo in the morning and his mouth was bleeding, and Anna may have seen that he had just been beaten in the morning, so his subordinates showed mercy.

He looked at his accomplices in one place, completely frightened, he wanted to find some friends outside the school to help him find the morning field and teach this kid who dared to beat him a lesson. Also let that pretty chick know the consequences of offending him. didn't expect this to be the end result, that is, that beautiful chick became their nightmare.

When he saw Leo walking towards him, his body unconsciously fell backwards, and he said with some lust: "Don't come here, what are you going to do!"

Leo smiled his standard wickedly and said, "Originally, I wanted you to apologize to Anna and promise not to look at Anna with that look in the future." But I've changed my mind now. ”
