Autumn winds blow through the valley.

In the center of the valley, a plastic baffle is enclosed in a circle, enclosing a test site with an area of about 300 acres. At one end of the test site, a pickup truck was parked, and in the compartment stood an astronaut with a walkie-talkie in his hand: "Liang Gong, you can start." ”

The glass mask on the astronaut's helmet is not lowered, and it can be seen that the astronaut is none other than Lee Myung-bak. In front of him, that is, on the front of the pickup truck, there were five horns, all painted blue and white, and these horns were neatly arranged and facing the front of the car.

"Boom!" The sound sounded, the plastic baffle on the left side of the pickup truck was removed, and a huge construction machinery transport semi-trailer galloped into the scene. The car was so huge that you could see that it was not loaded with any goods, but a concrete bridge with arches and railings, and it was spotless.

The construction machinery transport semi-trailer drove to a position about thirty meters in front of the pickup truck and stopped, and then two people jumped out of the front of the car, one of which was a chubby middle-aged man in a fiery red firefighting suit without saying a word, turned around and ran. Another thin young man wearing a hard hat and a tunic looked up and said to Lee Myung-bak, "It will definitely succeed!" Come on! He clenched his fist and shook it encouragingly at Lee Myung-bak. Even through the thick spectacle lenses on his face, you could tell that he was crying.

Lee Myung-bak laughed, "Liang Gong, don't be so excited!" I'm going to start, you run! ”

At this time, the open plastic baffle was slowly closing, and the beam worker ran desperately towards the gap in the fence, and the moment before the baffle was about to close, he ran out, only to be scratched by the sharp scale-like protrusion of the baffle.

Lee Myung-bak looked around the test site and could see that there was only dead grass and no buildings around. The plastic baffle that encloses the meadow is covered with the same kind of scaly, sharp protrusions, which mimic the scales of an ancient shark, and a similar structure that absorbs sound waves and prevents the powerful sound waves from harming people nearby.

Tall plastic baffles blocked Lee's view, and he couldn't see outside the test site. However, the atmosphere today seems to be a little different, and after many days in the army, Lee Myung-bak has become accustomed to the situation of suddenly hearing the sound of cannons during the test, but today is too quiet, and he feels as if he has been thrown into this test site in the mountains, as if there is no one around.

There is also the bridge built in the carriage of a semi-trailer for construction machinery. Experiments with infrasound to destroy bridges have been carried out five times, but the old bridge was rough as a cement lump, but today the bridge is so beautiful that it can even be called a work of art.

And the tears in Liang Gong's eyes......

Lee Myung-bak could feel that today's test was definitely not an ordinary test. He slowly lowered the mask on his space helmet - the main function of his spacesuit was to insulate infrasonic waves from damage to his body. He can emit infrasound waves from the mask, and convert the sound into electronic signals through the wireless microphone built into the helmet, and the speakers in front of him, after receiving the electronic signals, will be restored to infrasound waves, and the infrasound waves emitted by him will be amplified. The amplified infrasound waves are so powerful that the human body cannot withstand them, and even if the tweeter in front of Lee Myung-bak is said to have the function of transmitting sound in a directional manner, Lee Myung-bak still needs the protection of a spacesuit.

He was once told that the trumpets were worth a lot of money, and that each one cost more than $80,000.

Lee Myung-bak looked at the exquisite bridge through the glass mask, and suddenly became a little unconfident: the principle of infrasonic destroying the bridge is very simple, that is, to cause the bridge to resonate. But the recipe of the bridge, its shape, all affect the resonance effect, and the quality of the bridge today is significantly better than ever, which means that the test is likely to fail.

Lee Myung-bak exhaled softly, and then he stretched his arms and made a white crane wings movement—exactly one of the moves in Tai Chi, but Lee Myung-bak did it indecently. He made a few blind strokes of Tai Chi, felt relaxed, and then shouted the spell silently at the bridge in front of him:

"Boom-ah-boom!"

The yellow grass in front of the pickup truck suddenly writhed wildly, like a worm suddenly scalded by boiling water. The bridge built in the carriage trembled, and the concrete blocks fell one after another, and in a matter of seconds all that was left was the steel frame—infrasound was ineffective against metal, plastic, and other malleable materials.

Lee Myung-bak stood quietly on the car for a while, and the effect of this experiment was so good that he was stunned. "Could it be that the more exquisite the craftsmanship of the cement bridge, the easier it is to be destroyed by infrasound?" He thought.

At that moment, the gate to the proving ground, the plastic barrier used for passage, opened, and an old man walked in with applause.

"Section Chief Li! Congratulations! Your trial fills a gap in the country! From today, our country has infrasonic weapons! The old man announced. The old man was followed by the political commissar Feng, the number one in the army, and also applauded with the old man. Political Commissar Li was followed by a group of people, and it could be seen that there were important members of the army, staff members of government agencies, and some security personnel, and about 100 people, all of whom applauded together.

Lee Myung-bak lifted the glass mask and looked at the old man who took the lead in with a pale face, so nervous that he couldn't even speak. Because he recognized it, this old man was the head of the five.

It wasn't until the No. 5 leader walked under the pickup truck and stretched out his hand to him in a friendly manner, and the political commissar Feng on the side scolded anxiously: "Don't be stupid, boy, shake hands!" Lee Myung-bak came to his senses, jumped out of the car and shook the hand of the No. 5 chief.

Lee Myung-bak followed the No. 5 leader out of the test site in a daze, only to remember that many people came to shake hands with him, and they all said words of congratulations, but they couldn't remember what they said.

"You know what?" The fifth leader jokingly said, "My wife especially likes the way you play Tai Chi in a spacesuit." ”

This didn't make Lee Myung-bak feel relaxed, but made him more nervous. He only felt hot all over his body, and when he took off his helmet and held it in his hand, his face was still hot and sweaty.

The Fifth leader smiled kindly and asked a question: "How do you think infrasonic weapons can be developed?" ”

Lee Myung-bak finally spoke, and he said endlessly, that he wanted to make an infrasonic bomb, and the principle was very simple, the same as that of a tape recorder. As soon as such a bomb is dropped in the midst of the enemy, the enemy within thirty meters of it will be cleared, and no one knows how this happened.

"Infrasonic waves can kill." Lee Myung-bak explained simply, but before he could make it clear, he came up with the next idea: an infrasonic patrol car.

Assuming that a gang of villains occupies an important building and resists, it only takes a drone equipped with infrasonic weapons to drive towards them and let them all play without firing a single shot.

"The principle of work is very simple, and it can be achieved at the level of domestic production." He explained, again, and without waiting for anyone else to understand, he came up with the next idea: an infrasonic explosive device.

This weapon is designed to destroy important fortifications, and can be used in a similar way to a timed bomb. In Lee's vision, it could have five different models......

Everyone around was quiet, in fact, everyone felt that Lee Myung-bak was talking too much and too fast, and they basically didn't hear what he was talking about. And these people think that Lee Myung-bak is too rude, but it is understandable how excited a small section chief like him who works at the grassroots level should be to meet the fifth chief! So it's normal to be incoherent.

Chief Five listened attentively and personally opened the door to an office surrounded by a plastic baffle for Lee Myung-bak.

The office was built on a mountainside, about 200 meters away from Lee's testing ground.

The office was full of computers, and about 30 staff members were busy typing into them. Seeing the fifth leader coming, those people all stood up and respectfully shouted, "Hello chief." ”

Chief No. 5 waved for everyone to sit down, and then said to Lee Myung-bak, "You wait here." Then he took Political Commissar Feng and his party into the small door at the back of the office. The mermaids came in in order, as if they had been trained many times.

Lee Myung-bak had been in the army for nearly a month, but it was the first time he had entered this inconspicuous office, and he looked at it curiously.

Everyone in the office was busy, and everyone was typing into the computer, including drawings, equations, and a few in a foreign language that Mr. Lee didn't know.

Suddenly, an eldest sister who was about thirty or forty years old was wearing a work outfit and walked towards Lee Myung-bak with anxiety: "Hello Section Chief Li!" I don't know if I have time to guide me. ”

None of the people in this office Lee Myung-bak knew. However, the eldest sister in front of him had a kind attitude, and he nodded in a friendly manner.

The eldest sister said: "That's right, we have obtained a silent helicopter under the CIA, and the project I am responsible for is to solve the secret of the helicopter silence, but so far, I still have no clue." Your research on infrasound is obvious to all, and I hope you can show me the way. I won't do you any wrong. ”

Li Mingbo thought secretly: "Wasn't that silent helicopter obtained by Ren Qiuling?" "But he was in the secret department, and he knew that it didn't matter where some things came from, and no one dared to ask. He clenched his hands into fists and pointed them at the eldest sister.

"Now, I have 10,000 catties of strength in my left hand." He shook his left fist. "My right hand also has the strength of 10,000 catties." He put the two fists together, "The two fists met, and because the power was equal, they came to a standstill." I think this is the principle that a helicopter can be silent even though it flies. With nothing to break, the forces on both sides are balanced, and as a result, the sound disappears. ”

Lee Myung-bak thought he had made it clear, but the eldest sister didn't seem to understand what he said.

"Nothing? Balance of power? An expert in his sixties shouted, "This kid is farting!" Director Bian, you tell him that you are a national eighth-level expert, see if he dares to be presumptuous in front of you! ”

National Level 8 Expert, that's a very good character. Lee Myung-bak bowed his head and was silent, his face flushed.

The eldest sister who asked Lee Myung-bak for advice also made a straight face and said to Lee Myung-bak seriously: "Xiao Li, you are not right, I am ashamed to ask, I sincerely ask you for advice, why do you say something I don't understand?" Young people should learn to behave with their tails between them—"

Lee Myung-bak lowered his head and listened to the eldest sister's nonsense with a face full of shame.

At this time, the fifth leader walked out of the small door with a smile on his face, "Li Mingbo, I will discuss a matter with you." The expressions on the faces of the two experts immediately changed, from disgust to smiles. You talk, you talk. Director Bian said as he retreated with a flattering smile.

Seeing that Lee Myung-bak was a little angry, the fifth chief took him out of the office, and the two stood on the side of the mountain, looking at the scenery in the distance.

"Don't take what you just happened to heart. The old expert who scolded you loudly just now, he studied the Dream of Red Mansions, and specialized in researching what kind of relationship Miaoyu and Jia Baoyu had, and he didn't know any sonic knowledge. I put it around, mainly to let him tell the book to relieve his boredom. The fifth chief said, "What about the director of the border, she studied in the Soviet Union, learned to fight in the nest, became a director, and she had to name all the research projects of her subordinates, so the scientific research results are also very rich." In fact, he will be an official, and he has no other skills at all. ”

Lee Myung-bak was somewhat relieved.

The fifth chief said: "Infrasonic weapons have been completely regularized in developed countries, and the reason why they have not made them public is because they regard this kind of thing as a trump card and save it for use in real war." They have a lot of trump cards in their hands, and our country has fallen too far behind. Lee Myung-bak, the country needs you, and I want to build a laboratory specifically for you to develop infrasonic weapons. What do you mean? ”
