As for the person who spies on him, is it a completely private organization? Gao scoffed at this.

After a few minutes of staying a kilometer away from the hotel, he drove away, walked around again, bought something, and returned to Changming Island.

These people who are listening must be professional, so they must be very alert.

Staying in his vicinity for a kilometer for a long time will inevitably arouse his suspicions.

Indeed, when Gao Gao returned to the courtyard, Chitose told him that the man had left the room.

"It seems that the operation is still a bit aggressive, which makes them suspicious. ”

"Not necessarily, it may be that they are cautious, as for whether they perceive something, it depends on whether these signals will continue to be sent in the future. ”

Gao Gao nodded, he hoped that these people would be more patient, otherwise this game would not be fun.

"Can he crack the communication signal?"

"It's cracked, but it's a string of Arabic numerals. ”

The easiest way to send passwords, but they can't help it.

The codebook could be a random magazine, or a newspaper, or even a small piece of yellow paper.

As long as they don't have a codebook, it's basically impossible for them to crack the code.

Even if Chitose had access to all the written records, so what?

People can find a copy that has not been published publicly, or some copy that is printed casually offline, can be used as a code book.

"You keep studying, I'll go for a swim in the sea. ”

"Yes, sir. ”

Below this courtyard is the mouth of the Yangtze River, and as long as you jump from the roof, you can plunge into the sea accurately.

In fact, he did.

Why go to the sea?

Because Xiaohua's favorite fish is gone, and he doesn't want to go to the street again, after all, this trip is in vain, and his mood is not very happy.

It is said to be an estuary, but it is not deep, about five meters deep.

Due to the recent rain in various parts of the country, the water flow at the mouth of the sea is slightly turbulent compared to usual.

Gao Gao, who plunged into the water, immediately moved closer to the shore before scanning the underwater situation.

It's filthy, and there are so many floating debris that it's deadly, but fortunately, there are really some fish and shrimp mixed in it.

Take a deep breath, dive into the water, and swim towards a silver carp that is more than two feet long.

But Gao Gao overlooked one thing, he has a lot of places to borrow on land, so the speed will be fast.

He is now underwater, and the currents below the surface are even stronger than they seem.

Even if his two legs are swung like a turbocharger, his whole body still sways from side to side, retreating and advancing for a while, swaying from side to side, and he can't even control his body balance well.

"When I played big, I knew I should bring an oxygen cylinder down. ”

Gao Gao was a little panicked at this moment, and the breath he had inhaled earlier was almost used.

He had to get back to the surface and get some fresh air, or he would risk drowning.

People are at a loss in times of crisis, and he is no exception.

Originally, he was going to swim to the water, but the balance of his body was no longer under his control, and the more he tossed, the farther and farther away from the water.

"Hold the grass, something is wrong, labor and management won't really be drowned, right?"

The air in his chest is also getting less and less, and Gao can even feel his cheeks start to heat up.

He knew that this was a delusion, but the fear in his heart was telling him: if he didn't go up again, he might really die.

In a hurry, Gao roared angrily: "Ah!"

A terrifying ripple visible to the naked eye, centered on his gaping mouth, vibrated wide.

Suddenly, as if under some invisible attack, the tail of the fish that was swinging stopped swinging, and the mouth of the bubbling fish stopped bubbling.

The fish belly turned over, like a broken rag, drifting with the tide.

This roar is Gao Gao's struggle before dying.

However, after this roar, he felt less uncomfortable.

The feeling of lack of oxygen was gone, and he regained control of his body.

I didn't have time to think about anything, so I quickly reversed my body, regained my balance, and swam to the shore.

He took a few breaths and wiped the seawater from his mouth, only then did he notice the abnormality on the water.

"Hold the grass, why are there so many dead fish?"

There wasn't that much before you entered the water, and all of a sudden it's like this?

Let's not think about why it became like this, Gao Gao immediately re-launched the water, these are Xiaohua's rations for the next few days.

This time he learned to be obedient, and instead of diving any further, he stayed on the surface.

After a few trips back and forth, I got more than a dozen silver carp and crucian carp, and then I squatted on the shore and recalled the thrilling scene underwater.

"It seems like all of a sudden you don't feel depressed, and then you go back to the shore?"

"I seemed to have roared before, could it be that these fish were shocked to death by me?"

"After the body mutates, the sound waves emitted by the glottis are aggressive?"

"But don't you feel depressed, what's the matter?"

When a problem is found, it is necessary to analyze the problem.

"Sonic matter, find a time to change places and do experiments again, and the situation is not boring underwater...... You can try again. ”

Back underwater, this time he learned to be obedient, just diving his head underwater, and pulling a rock on the shore with both hands to prevent the danger from recurring.

It took ten minutes for him to pull his head out of the water.

"Hold the grass, something happened again. ”

Underwater, he was able to get oxygen without breathing.

When he submerged his head under the water, he could feel as if the cells in his body had opened an opening.

Poor oxygen particles are drawn from the surrounding free air, moisture.

A normal person must get oxygen supply from the mouth and nose, and he is equivalent to having a mouth and nose all over his body from that moment on.

He did not believe in evil and repeated the experiment many times.

The whole person dives underwater, the upper body is upside down, the lower body is upright underwater, and even one leg is stuck in the water......

[August 1st, Changming Island estuary, sunny;

The body mutates again, this time with two discoveries:

1. The mouth can emit sound waves, which can be aggressive, because many fish and shrimp have died...... But I didn't think it was loud at the time;

2. The oxygen needed for respiration can be obtained through the cells on the surface of the body. 】

For the first point, Gao Gao has a hypothesis:

He was very sure that the sound he made at that time was the roar of ordinary people, and the maximum would not exceed 100 decibels, which was the level of a decoration drill.

With this kind of decibel force, it is impossible to kill those fish and shrimp.

Then there is only one possibility, there is something wrong with the frequency of the sound waves.

Gao Gao wanted to do this experiment, but he couldn't now.

The place is not suitable, and there are villagers living around, although it is very sparse, but the sound waves that can kill fish indicate that it is harmful to animals, and humans are not immune.

He had heard before, and the "neighbors" 800 meters away were indeed affected.

Several people felt so bad that they even started vomiting and were short of breath.

However, after this period of rest, everything has gotten a lot better and has returned to normal.

"Fortunately, it is underwater, and there is sound insulation from seawater, otherwise the consequences are unimaginable. ”

It's all a fear when you think about it, if it's because of your own carelessness...... Then he will feel guilty beyond measure.

As for the second point, it was only his guess.

Because he wasn't sure that what he was absorbing was oxygen particles, and according to his understanding, wasn't it oxygen that could make people breathe?

But again, the question arises, why does the human body need oxygen? because it needs to be respirated;

Why do we need respiration? Because we need to break down energy to supply the body's functions;

However, if his body itself is a solar cell, he can obtain energy from sunlight and does not need to photosynthesize.

As for why he is still breathing, it may be that his body has not yet evolved?

Just like the evolution of apes, you have to take it one step at a time?

These questions were all Gao Gao's own imagination, and he didn't know what the facts were.

But one thing he was sure of: he could breathe underwater, and that would be enough.

His body was a mystery in its own right, and it grew bigger and bigger as time passed.

Fortunately, he is also keeping pace with the times, and I think there will come a day when he can solve all the mysteries.

Back inside the house, Gao communicated Chitose about his experience and speculations, hoping to get his inference.

"Sir, I already know a lot about what you just experienced through the external camera and radio. I agree with your first guess, and it has proven to be valid. From 04 to the present, most countries in the world have purchased sonic weapons, among which the most widely used is the long-distance directional sonic equipment of Innova, referred to as: LRAD. ”

"This kind of sonic weapon is not very lethal, and it is mainly used to warn and disperse the crowd gathered in the target area. ”

"But the sound waves you emitted just now, sir, can basically be summarized as infrasonic waves, compared with LRAD, the transmission distance and penetration of infrasound waves have obvious advantages, the most important thing is that infrasound waves will only harm organic life, will not cause environmental pollution, will not destroy hardware equipment. ”

"So, sir, this new ability of yours, if you control it well, it will be a very big guarantee for your personal safety. ”

Gao nodded in agreement.

When Chitose was communicating with him, he had already transmitted the information related to the sonic weapon.

"This infrasound wave has to find a time and place, and train it a little, and the ghost knows what the person who eavesdropped on us is thinking, and it's not wrong to have a bit of a precautionary means of self-defense. ”

In the past, he was a little resistant to this kind of aggressive ability.

The main thing is that he is afraid that he will become the dragon slayer boy and eventually become an evil dragon.

And there was a time before when he would have a sense of violence from time to time.

I don't know if it's because I went to the mountain country, or because I was on the way from the sand country to the mountain country, and the violence in his body was released, and Gao Gao now feels that the whole person is very clear.

The previous violence has basically disappeared.

Coupled with the fact that various strangers have approached him recently and even want to spy on him, the uneasiness in his heart has become stronger and stronger.

If these people dare to attack themselves, it means that they dare to attack other normal people.

For these wicked people, when it is time to punish, they must be punished severely.

"Sir, there is something that will surely interest you. ”

"Huh?"

"The notebook you brought back last time was cracked by me, and there is something in it that may have something to do with Robert's superpowers. ”

"Pass it on. ”

"This laptop is the same as you thought, it does have a tracking system, but it's dormant now. ”

As he spoke, Chitose transferred the relevant information from Robert's computer to him.
