They didn't have to communicate with No. 1, they all stood by and didn't use codeword, and they could hear them very clearly.

"It should be an established process, don't say anything, everyone knows it. The lab asked us to set our own order, then according to our respective numbers, I don't know if you have any better opinions. After the contact was severed, Number One looked at the other three and said, his face always serious.

Silence means acquiescence, and when No. 1 nodded to himself, and wanted to explain something, the printer connected to the communication machine sounded a "beep", and the paper with the material needs stretched out. However, there is no specific name of the material on it, and it is all identified by the number of goods.

The prompt was tomorrow morning, and Number One put the paper away, ignored the other people's gazes, and went back to his room. Kasia also turned to leave, and he thought about it for a while, but the focus was still on the few glass test tubes that he had broken in the laboratory-based earthquake two or three days ago.

"Could it be that there is something else?" Back in the room, Kasia chose to empty her head and continue her research on high-frequency sound waves, also ultrasound. Sufficient theoretical knowledge preparation, how to improve the use of high-frequency sound waves, how to control them, etc., Kassia has traces to follow. However, there will definitely be some difficulties in the specific implementation, and at present, you can't practice at will in this small building, and you can only try to complete the details in each link by thinking as much as possible, so that in the short patrol time every day, the experiment can be successful in one step.

Life suddenly finds its regularity. The next day, I went to the warehouse on time at 9 o'clock in the morning, opened the tight alloy protection door of the warehouse with the real-time password given by the laboratory base, took out the materials from it, and sat on the transport in the tunnel according to the information handed over on the fifth day, and went to the cavity at the end.

Everyone knew what was going on, but after the first delivery of supplies, it was inevitable that One would not become the object of other people's attention. In the sonic pulses, both Two and Three emit their senses, gathering as much information as possible. But after all, they have never been to the inside of the tunnel, what is the situation inside, how will it be, they can't have a rough estimate like Kasia, they can only rely on imagination.

The matter of Number One was a hiccup that failed to affect Kasia. Every morning at six o'clock in the morning, after resting and basic washing and warm-up, at half past six, Kasia left the small building on time and went to the town to explore according to the established route. In just a few days, Kasia had unilaterally acquired an unusually familiar ear for the town. Some of the protection personnel dressed as military personnel were also observed one by one. Originally, a patrol would take two hours, but for the sake of training high-frequency sound waves, Kasia extended it by an hour. After the people in the small building did not react in the slightest, Kasia extended the patrol to four hours the next day, purposefully practicing the control of high-frequency sound waves.

Once the high-frequency sound waves had a certain directionality, Kasia began to study how to reduce the curvature in the direction so that the accuracy was as small as possible. The current direction is a sixty-degree arc, and in just one day of practice, Kasia can switch between fifteen and three hundred and sixty degrees at will. But it is far from the goal that Kasia himself has set.

As a result, high-frequency sound waves can be like a strong flashlight, almost condensing the light into substance, pointing in any direction at will with the control. If the diameter range of high-frequency sound waves can be controlled within 10 centimeters, whether it is the vibration caused by high frequency, or the impact caused by the extremely high pressure of sound waves on the air, or the oscillation of matter caused by the high frequency of sound waves, etc., it can achieve a considerable power. At present, the power of high-frequency sound waves can not only shatter some ordinary glass products, but also cause the water shrouded in sound waves to collapse into a mist.

As for the impact effect, it is already a common thing to blow up the surface of the river. It's just that freedom is confined to this town, and Kasia can't find a suitable position to test her current limits, so she can only consider the problem of containment accuracy and control first.

On the third day after No. 1 delivered the supplies to the laboratory base, No. 2 received the name and quantity of the supplies and went there at the same time in the morning.

Three days ago, the number one who went out in the morning only returned from the tunnel in the evening. I can't see any change in expression, the four of them are like air to each other, there is no interaction in information, and the rest is all up to everyone's imagination. However, the period between the past and the return of the One naturally became the standard.

I think about what I will see and what I will do when I go to the laboratory base. Testing?Learning?The organization's laboratory was unknown to the minds of the four, and the other three knew better than Kasia. If you divide the organization into several parts, the laboratory base is tantamount to occupying the largest part of them. It is too high to think that other departments are serving the laboratory, but in fact, most of the tasks and things are related to the laboratory base, which is undeniable.

Kasia had no interest in any of this, knowing that his route in the organization had been arranged, and that route would not suddenly disconnect as long as there were no major problems in between. The man behind Adolf was definitely one of the top members of the organization, which made all his worries seem like a joke about a child scared of a toy being snatched away by an adult.

Still following the established rules of life, high-frequency sound waves increase control proficiency at a visible rate every day, which is enough for Kasia to be happy.

Nine days later, Kasia and Three were handed over to patrol at night. There are a little more things to do at night, and the number of patrol circles becomes two, and the range is about 1.5 times that of the day. In line with Kasia's intentions, the quiet of the night and the large area allowed him to experiment with some of the things he had concerns about during the day.

He was only in the small building from 1 to 3 a.m., and after getting used to the atmosphere of the small building, Kasia knew what he was doing, and the other three probably didn't bother to ask a bit.

In nine days, compared to the previous one, the progress has made the use of high-frequency sound waves in a different state. At four o'clock in the morning, after the last round of patrol, Kasia determined the location of the other three and went to the bank of the river on the edge of the town. Water is the most suitable test subject, as there is no need to worry about leaving traces of damage, and at best it creates a little noise.

A circle of fifteen degrees diagonally and fifty centimeters in diameter, Cassia set a corresponding standard for herself, and then turned her back to the river, and only turned her head to look there. Under the pale moonlight, the calmly flowing river suddenly burst into a series of rapidly spreading ripples, spreading to both sides, like a huge fish underwater, breaking through the river with its fin horns.

In the next moment, these ripples became more violent, and countless water droplets rose from the surface of the river like boiling, and the water droplets formed a spiral shape that spread out one by one, and were dragged by an invisible force to float on the surface of the water at a height of about ten centimeters. When the sound of "humming" was heard in the quiet night, a circular hole on the river surface suddenly appeared slightly inclined downward, directly separating the river surface more than ten meters long. The cylindrical cavity is filled with a thick mist, and the river water is attracted to the cylinder, pouring into the cylinder from around the cylindrical cavity, but when it enters the range of the cylinder, the river is shaken into mist at a very fast speed, and then rushes forward with the cylinder, bombarding the bottom of the riverbed.

More than ten meters away, a turbid bulge swelled up on the surface of the river at the same time, which was a whirlpool that swirled outward, and countless water mist emerged from there, like a thick steam, spreading out on the surface of the river. After more than ten seconds, Kasia, who had determined the result, stopped emitting high-frequency sound waves, and the cylindrical hole disappeared in an instant, filled with river water, leaving only a still boiling river surface that gradually returned to calm.

"It seems to be affected by the medium. "Kasia by the river muttered to himself, and the experimental scene was all captured, recorded in his head, ready to be called upon at any time to observe and analyze.

As he spoke, he looked at the open space across the river, and at the end of his line of sight, after sensing the distance alone, a "whirring" wind exploded silently. More than a meter in front of Kasia, a translucent cylindrical air channel with a diameter of fifty meters suddenly formed, instantly impacting into the distance at an extremely fast speed.

High-frequency sound waves drive the formation of air, which is a visible physical air channel, round and with a streamlined pattern of rapids on the surface. Like a column that has a gravitational attraction and is never filled, the surrounding air is sucked into the air tunnel under the pressure difference caused by the velocity, and it converges within it and shoots forward. As a result, a disturbed airflow forms in the blink of an eye.

The air corridor is called an air blaster, perhaps more vividly, Kasia thought. His original intention was to form such an attack. The translucent air channel began to spread out after hitting forward about fifty meters away, and the round cylinder finally expanded sharply there, becoming a horn, and the compressed air dispersed with a gust of wind, and finally slowly dispersed to restore calm.

At close range, there will be considerable impact force, but when the distance is too long, the fineness of the control will always cause these forces to disperse. The specific phenomenon is that the cylinder of air shock wave that has just disintegrated no longer has any effect except for a gust of wind.

There are many problems with control, and Kasia wants to reduce the high-frequency sound waves to form a ballistic line thickness, and carry out a bullet-like attack that the enemy does not expect. It certainly doesn't break bones, but when it lands on the eyes, heart, throat, and other organs of the body, it can cause great damage.

The process of achieving this power is still a long one, requiring extreme control and the extremely high energy of the high-frequency sound waves themselves. The vibration in his throat would be the key point, and Kasia could see her approximate limit in the past nine days, using the air blast driven by a high-frequency sound beam to destroy the wall of an ordinary building. For the surgeon, this is an attack that does not require defense and care.

At the moment, the use of high-frequency sound waves to disrupt the balance system of the enemy's body is the most effective means of attack in a short time.

Wait until the restlessness around him subsides, and Kasia probes around and there is no suspicious phenomenon, then he goes back to the small building. There was no mistake in timing, tomorrow morning at nine o'clock would be the time for him to deliver supplies to the laboratory base. What is in the laboratory, and what will be experienced after the past, Kasia is intrigued. He also wanted to know what the many laboratories that existed in small countries were carrying out experiments and research for so long periods of time, as the heart of the organization.

After resting for two or three hours, at half past eight in the morning, Kasia waited for the list of materials at the printer in the hall, and then got the real-time password, went to the warehouse to take out the corresponding materials, and neatly placed them in the minecart-like mobile car. Inside the moving car, Kasia pressed the start button, and a string of lights in the tunnel lit up, and there were also two bright searchlights on the car. Slowly speeding up, the trolley followed the track to the cavity 14 kilometers away.

Everything was standardized, and all Kasia did was move things from the warehouse into the cart, and from the cart they moved it to the metal pallets that had been placed in the cavity. There was a prompt on the tray for visitors to wait, and after a few minutes, the sound of the elevator made Kasia look at the slowly opening security door.

A skinny man with glasses, wearing a white hazmat suit, pushes a simple crane cart and transports metal pallets into the elevator while motioning for Kasia to go back with him.

"Don't wander around after you pass, just follow me. The thin man said.

"Is there a process in place?" replied Kasia, the thin man looking at him with a smile, "Of the four, you're the only one who answered me." ”

Kasia gave him a puzzled look, and in an instant, he figured it out. The other three have been in the organization for many years, and they are the only ones who have only joined the organization, and Adolf has very little information for himself, and the style of doing things will definitely not be the same. Without replying, Kasia pursed her lips and counted the height of the elevator in her mind.

Naturally unfamiliar with the scene, Kasia focused on the thin man in front of him, but he also naturally looked elsewhere, making up for what he had seen in the sonic detection ten days ago. The thin man leaned on the password card and password command to open the door of his front teeth, and the warm wind designed in the constant temperature room rushed out. The laboratory is characterized by a consistently monotonous cold glow, metal floors, square-shaped passages, and large and small rooms on both sides of the passages.

Kasia tried to keep her strength in check so that her abnormal weight didn't show up. After walking a little distance, the thin man pushed a pile of supplies to the fork in the passage, where he waited for a short while.

When the thin man disappeared behind a pneumatic gate, Kasia tilted his head to look around, and after a moment's thought, the sonic pulses spread out, and he immediately loaded the outlines of most of the surrounding buildings into his head.

Meanwhile, in the utterly quiet room on the other side, Professor Mosier and Bennett, along with another researcher, stood still in their seats like statues. Breathing and heartbeat are suppressed. The three looked at the silent time counter on the wall, waiting for something.

Suddenly, on the table where the three of them were sitting, there was a small sound of "zizi" from a metal box. But Professor Mosier suddenly had a satisfied smile on his face, and he immediately got up and opened the metal box, and took out the monitor that was vibrating slightly.

"Bennett, go to Zagavaar and bring someone over, we'll wait for him in the conference room. ”
