Chapter 43

"Your vocal range is very wide, including not only the ultrasonic waves in the high-frequency sound area that cannot be heard by human ears, but also the very low-frequency 4-8 Hz and very slow infrasound waves!

This kind of sound wave widely exists in our life, such as the bumping of the car, the shaking of the hull, etc. when these vibrations are just within the range of infrasound wave, they have a great impact on people.

It can make you carsick, seasick, even headache and vomiting. The same situation will also happen in spaceships. Therefore, your ability may be the most useful against alien spaceships in the future! "

"That's true. Sometimes she talks too much. I really want to vomit!" Song Xiaojia laughed.

"You die!" Zhang Dian replied, "I'm so capable? Just make people want to vomit?"

Lin Tao smiled and shook his head: "of course not. Because the frequency of infrasound is very low, the absorption coefficient of the atmosphere to infrasound waves is very small, so its penetration is very strong, it can spread to a very far distance, and the energy attenuation is very small. Infrasound waves below 10Hz can spread to thousands of kilometers.

In the summer of 1983, karakato volcano, located between Sumatra island and Java island in Indonesia, erupted. The strong infrasound wave generated by the volcanic eruption turned around the earth three times and disappeared slowly after 108 hours.

Micro barometers all over the world have recorded its vibration afterwaves. In other words, if there is another one in the world who is standing in the United States, you two can have a direct dialogue, although the speed is a little slower, because the air conduction speed of sound waves is really not flattering... "

"That's just talking to each other. I'll wait 108 hours to hear a word. It's better to call directly. What's the use?" Zhang Dian pouted discontentedly.

"You underestimate yourself. In my opinion, you are the most destructive one among you. Song Xiaojia has to contact each other no matter how powerful he is, and you can kill people across the air!"

"Burp? What burp? Can you kill each other with a burp?" he opened his eyes and looked suspicious.

"If you understand this, it's OK. You should know that the tissues and internal organs in the human body are very sensitive to infrasound waves. It's easy to absorb the vibration energy of infrasound waves and vibrate strongly. If you master the method of sending out infrasound waves, you can make the enemy's heart beat wildly, failure, even rupture of lung wall and liver bleeding ... that's the real way to kill people! "

"My God!" Zhang thought a little, "this is the real way to draw a circle to curse you. Just reciting the curse can kill each other!"

"Unfortunately, you haven't learned to use this ability yet, otherwise who can catch you!"

"Just cover her mouth, isn't it?" Lele suddenly asked Lin Tao curiously.

"Silly boy, her infrasound wave is emitted through vocal cord vibration. It doesn't need to be transmitted through the mouth at all. The muscles around your neck and cervical spine bones can be used as the medium to transmit vibration to the air."

"Even if you can't cover my mouth, you can also cover your own ears. Just don't listen!" asked little by little. She seemed very eager to understand her ability.

"Sound insulation and absorption methods do not work for the strong penetration of infrasound waves. 7000hz sound waves can be blocked with a piece of paper, while 7Hz infrasound waves can not be blocked with a thick wall. Infrasound waves can penetrate more than ten meters of reinforced concrete!

Well, I'll give you an example. It's much easier to understand. You can use your infrasound to kill the soldiers in a tank division in front of you. Any weapon that needs to be controlled by people is invalid for you!

That's why my army needs your ability so much!

If a hundred soldiers like you are copied, no matter what kind of spacecraft aliens drive to attack us, they will be defeated by us! "

"Can your army be named 'Zhang Dian's Choir'!" Zhang Dian shouted in a whim.

"Good idea, I'll think about it! Well, this is the end of the theoretical analysis. Let's see how far your ability can be strengthened?" Lin Tao stood up and walked to the middle of the three.

"Strengthening?" Song Xiaojia was more sensitive to the word "strengthening." can my strength still grow? "

Lin Tao nodded affirmatively: "of course, according to the calculation results simulated by our computer, your current ability is only a small part of the real power hidden in your body, just the tip of the iceberg..."

"How do you strengthen?" Song Xiaojia asked curiously as he looked at the technicians around him.

"Through our technical means, help the power in your body wake up quickly. Perhaps in the future, with the progress of time, you will eventually reach the strongest. However, I have no time to give you, or human beings can't afford to wait. In no more than a month, the human world will be completely destroyed... So we must take some unconventional measures!"

"Unconventional means?" Song Xiaojia was stunned, and then saw a man wearing light blue overalls, masks and similar doctor hats coming towards him. His eyes were very cold, holding a syringe in his hand. In the transparent needle tube, a bright yellow liquid was faintly fluorescent

"This is a chemically synthesized formic acid purified from 40 ants. It is an enzyme that can catalyze adenosine triphosphate. If it works, it can increase the secretion of ATP hormone in your body thousands of times!" Lin Tao said, pointing to the potion in the needle tube.

"Stop! I don't want it!" Jia Jia screamed. "You'll turn me into a super monster!"

"No, maybe there will be a little side effects, but you don't have to worry at all!" Lin Tao said with a smile. "At most, change your shape. Have you always seen the Hulk movie?"

Although Jiajia's academic performance is not very good, she also understands what the other party is saying: "what? Side effects? Female Hulk? I don't want to... What's the meaning of living if I become so ugly?"

"I can't predict. Maybe it's the muscles all over your body. Fortunately, you look good. At most, you're a muscle Basket!" Lin Tao waved to the medical staff indifferently and motioned to inject invertase into song Xiaojia.

"Ah? I don't want to. If my arms are thicker than my thighs, how can I wear a suspender skirt!" Jiajia didn't want to be a female man for the first time. She was tied on the hospital bed and struggled desperately to avoid opening the slender needle. Lele and they were too anxious to shout, but they couldn't help

"Another thing to explain is..." Lin Tao didn't make a sound, but deliberately stopped for a while.

A few girls instantly quieted down and listened to what he was going to say.

Lintao paused and continued: "This formic acid is extremely toxic. Normal people can't bear it, so they have never carried out human experiments, but it is feasible in theory. Because we found you late, we didn't have time to carry out a comprehensive clinical test, so you have to bear the risk yourself. If you don't survive the torture of this toxin and die... Please don't blame me!"

"My God!" Lele shouted, "it doesn't include the poison of bullet ant?"

"What? What bullet ant?" Song Xiaojia was nervous and hurriedly asked.

Lele stared at her: "as our biology teacher said, there is a special kind of ant, which is very large and has strong toxin. It seems to be called" bullet ant ". It is said that being bitten by it is more painful than being shot by a bullet. It is the most painful of all insects.

It can bring people waves of baking, twitching and forgetting pain. Moreover, this suffering can last 24 hours before it gradually weakens! "

Great pain day and night! I'll bend your uncle's!

Song Xiaojia's eyes stared in horro
