An ordinary surface-to-air missile costs at least four million yuan, and in order to intercept enemy aircraft, it will usually be launched in double or even triple to ensure that the target is shot down.

In other words, an average of [-] million can complete an interception mission, and when a real war breaks out, the air strikes that China will face, including fighter planes and ballistic missiles, are at least calculated in units of thousands.

In order to win, China has to grit its teeth to burn money, but the most embarrassing thing is that with China's current technological level, the possibility of intercepting the most advanced stealth fighters or ballistic missiles is only theoretical.

No one can guarantee that the enemy's planes or missiles will really start to invade China, and China's missile forces will indeed be able to shoot them down.

In fact, everyone knows that shooting down can definitely be achieved, but it cannot be achieved [-]%, perhaps not even half.

And what if the enemy's stealth strategic bombers, or more extreme, long-range ballistic missiles carrying nuclear warheads are missing?

Even if only one is missed, given the concentration of China's population, it will be an unbearable pain

And if this bow and arrow really has such magical effects as Lu Yun said, then China's air defense capabilities can be greatly improved

The country's most important weapon, this is the real country's most important weapon

All the military leaders felt that their breathing was a bit difficult, they were panting heavily, and looked at each other with blood red eyes.

Everyone has already realized the huge improvement of China's military power at this time, and now there is only one problem left.

He's blowing so mysteriously, isn't this kid trying to fool everyone?

Chapter 73: Under the Sea! (seeking subscription)

Chapter 73: Under the Sea! (Seeking subscription) Seeing the excitement of the military leaders, Lu Yun found that his words were a bit misleading.

Although the old professors are also very excited, they are also thinking about Lu Yun's words at the same time, and they are a little calmer than the military leaders.

At this time, a gray-haired female professor asked, "Xiaoyun, the bow and arrow you mentioned has a long range and great power, but how about the accuracy?"

Lu Yun thought for a moment, and replied, "I don't know, this needs to be tested after the production is completed."

The dean pondered, "In this case, although it has the range and power of anti-aircraft missiles, it cannot replace anti-aircraft missiles, but it is much more useful than anti-aircraft missiles in small-scale operations."

Professor Wang nodded, "I think this weapon should be used for offense, not defense."

Hearing this, all the professors' eyes lit up, and they nodded repeatedly, praising that it made sense.

Lu Yun couldn't help giving Professor Wang a thumbs up, and said with a smile, "Professor Wang is right, this bow and arrow is powerful, but after all, it is man-made, and it is very difficult to shoot missiles with it. However, it is not impossible to realize it, but compared to attacking with bow "[-]" arrows, it is still a little passive."

"In my vision, this bow and arrow is still a conceptual light weapon, used for small-scale warfare, it can shoot the enemy's war tools, or shoot the enemy's barracks at a long distance, similar to missile strikes, but our bows and arrows cannot blocked"

"As for air defense, I haven't thought about it. It's a bit difficult to realize."

After all, the bows and arrows are man-made, which cannot keep up with the radar's response speed and accuracy. Unless the bows and arrows also have self-tracking sensors, it is possible to use arrows to intercept extremely fast flying missiles.

But it's a pity that the Hanzo bow and arrow is not like a policewoman's sniper rifle, and it doesn't have the function of bullet tracking.

The military leaders also calmed down and nodded slightly, knowing that what Lu Yun said made sense.

Lu Yun smiled and said, "Our air defense has some shortcomings. I will try my best to study this aspect in the future and strive for improvement."

With the system, there is absolutely no shortage of black technology, and the system also has an upgrade function. In the future, let alone air defense, even new energy can be researched

"What's the principle of this bow and arrow?" Unable to restrain himself, a military boss pressed his hands on the table and stood up, asking urgently.

"Hehe." Lu Yun smiled slightly, "You don't understand even if you tell me."

The bosses almost vomited blood when they heard the words. Looking at Lu Yun's smiling face, they wished they could punch him so that their faces would bloom.

Can't beat it, the bosses sighed.

There is a sniper rifle that has proven its magic in front of everyone. Even if you doubt it, you can only serve this master well.

What if everything he said is true and there is no lie?

And thinking about it calmly, even if he couldn't make the bow and arrow he boasted about, having this sniper rifle alone was enough to gain his current status.

Although the role on the battlefield cannot be evaluated yet, at least when the war comes, holding this gun to perform beheading tasks is a sure thing.

In addition to being able to snipe and kill the key figures of the enemy and destroy the enemy's organization and structure, it can also cause huge panic, which is also a sharp weapon enough to influence the situation of the battle.

Just imagine having such a gun, if it says it wants to kill you, it will definitely kill you, no matter where you hide, are you afraid?

The military leaders looked at Lu Yun with desire and dissatisfaction on their faces, but there was nothing they could do.

The chief also gave Lu Yun a helpless look and shook his head slightly.

However, in his opinion, as long as Lu Yun has something that can make the country move forward even a small step, everything else can be accommodated.

The chief cleared his throat slightly, and after attracting everyone's attention, he turned his head and said to Lu Yun, "Can the bow and arrow you mentioned be made with our current technology and materials?"

Lu Yun quickly read the production process and materials given by the system in his mind, and nodded, "Technically, there is no problem. The only problem at present is that there is still one key material missing, which is not available in the research institute."

"What material is it?" the chief asked.

"70 manganese." Lu Yun replied.

"What is the difference between it and metal manganese and what role does it play?" The chief obviously didn't know much about elements and the like.

Lu Yun thought for a while, skipped the question he didn't understand, and replied, "This metal is a necessary material for making energy firing control equipment for bows and arrows. It is precisely because of the existence of 70 manganese that it can be injected with energy in such a way that the air forms a solid arrow."

The chief looked blank. Lu Yun's description made him feel like he was listening to an online fantasy novel.

He turned his face to the audience and asked, "President Wang, Academician Chen, do you know this metal?"

Dean Wang shook his head, "I haven't heard of it."

The chief's face froze immediately.

Unexpectedly, Dean Wang took a big breath, paused, and then continued, "I study the mechanical structure of firearms. Regarding materials, it is Academician Chen's specialty."

All eyes immediately focused on Chen Suyan.

Chen Suyan was thoughtful, "I also haven't heard of this 70 manganese, but"

"But what?" a military boss asked anxiously.

Chen Suyan organized his language carefully, and then said slowly, "Listening to the name of this new material, it should be one of the isotopes of manganese metal. So far, we have discovered a total of twenty-four isotopes of manganese metal, numbered from 46 to 69."

"Isotopes of the same element have mostly similar chemical properties, and only differ in the nature of the nucleus. For example, manganese, the most commonly used metal, is a stable metal without radioactivity, but its isotopes are All exhibit trace amounts of radioactivity."

"And we have also discovered some common characteristics of these radioactive isotopes. For example, the isotope numbered 54 has very low radiation itself, but it is sensitive to other radiation, such as X-rays, gamma rays, etc., and even electromagnetic waves. Extremely high sensitivity, so it is generally used to make radioactive standard solutions to test the radioactivity detection of certain materials”

"Not only the No. 54 isotope has this characteristic, but almost all metal manganese radioactive isotopes have similar characteristics, and the higher the number, the more obvious this characteristic is, but the isotope with the highest number is also radioactive. Therefore, it is not suitable for practical use."

"As for the isotope numbered 69, we have also done research on it. In addition to its sensitivity to radiation, this isotope also exhibits extremely sensitive magnetotropism and can respond to some extremely small electromagnetic fields."

Chen Suyan glanced at Lu Yun, and said meaningfully, "This kind of tiny electromagnetic field generally exists in some specific objects, for example, various sophisticated electronic instruments. The research on the 69 isotope has been going on, and we Trying to apply this feature to the guidance system, unfortunately, has not been able to find a suitable method."

"This kind of research is carried out in secret. The outside world doesn't even know that No. 69 isotope still has this characteristic, let alone that we are conducting research on this characteristic." Chen Suyan made the final conclusion.

The military leaders looked at Lu Yun in surprise, but Lu Yun's expression was indifferent.

Chen Suyan made it very clear that although she didn't know the existence of No. 70 isotope at all, judging from the characteristics of No. 69, No. 70 is very likely to achieve the effect Lu Yun said.

However, Lu Yun's life experience has been clearly discovered, and he has never had the opportunity to come into contact with such core secrets.

Could it be that Chen Suyan told him

No, it's impossible. Everyone knows what kind of person Chen Suyan is. She has a very measured heart, and it is impossible for her to make such a leak.

Then there is only one explanation, that is, Lu Yun is not bragging, he really knows a method of designing and making bows and arrows.

At present, this kind of bow and arrow is 10 times better than the most advanced surface-to-air missiles.

The cost of a surface-to-air missile is at least [-] million yuan, and the cost of some advanced models is as high as [-] million yuan or more.

And Lu Yun made it very clear that this kind of bow and arrow does not need arrows, but energy arrows.

How much money can be saved by replacing the expensive surface-to-air missile with an energy bomb?

"Very good." The chief patted the table excitedly, glanced at the faces of Lu Yun and Chen Suyan, and asked a question that everyone related to.

"Where can I find this 70 manganese"

"Under the Sea" Lu Yun replied firmly.

"Yes, the seabed." Chen Suyan said, "Most of the isotopes are associated. Where you can find isotope 69, you can probably find isotope 70."

"The place with the richest manganese resources in the world is on the seabed, deep-sea manganese nodules"

A chapter of [-] words, I will never deceive readers in terms of word count, how long can it last

Chapter 74: Aftermath (Subscribe)

Chapter 74: The aftermath (seeking subscription) "Since we can find it on the seabed," the chief made a decisive decision, "then we will immediately send a detection ship to find a suitable mining site."

He looked at everyone with piercing eyes, "This matter is classified as top secret, top secret, and everyone is not allowed to disclose the content of today's conversation, do you understand?"

"Understood." The military chiefs present answered neatly. Of course, they knew that once this kind of thing was known to the outside world, it would definitely cause an uproar.

Other countries will definitely use all means to spy on this secret. Even if they can't get this secret, they will find a way to destroy Lu Yun so that China can't get it either.

"Now, pass on my order." The chief's face is very serious, "Any act that hurts Lu Yun, or intends to hurt him, is regarded as a provocation against China, and its nature is consistent with the invasion of China's mainland. We will not hesitate Fight back at all costs"

The military chiefs were sitting upright with serious expressions on their faces.

China has always been pursuing the path of peaceful development. In order to avoid dragging the people into the abyss of war, most international disputes will choose other solutions instead of resorting to force.

But what the chief issued at this time was a war mobilization order. 16

The nature is consistent with the invasion of China's mainland, which means that the chief has equated Lu Yun's safety with China's survival.

Hearing this sentence, Lu Yun himself was a little stunned.

When did I become so important

He was slightly at a loss, and whispered, "Chief, is this too serious? I still want to be a free-spirited ordinary person."

"No," the chief interrupted him with a serious face, "With these new concept weapons you invented and produced, China's national defense and military strength will be greatly enhanced, and China's international status and voice will be greatly increased. On one point, Lu Yun, you can be called a national scholar of China, and you can't take it too seriously."

"As for ordinary people," the chief sighed and comforted, "You are destined to be unable to be an ordinary ordinary person, but you will always stand higher than anyone else. You will lead our nation to overlook the whole world The whole world is under your feet, this is your life"

Lu Yun's expression also became serious, and he said solemnly, "For the sake of the nation, I will do my best."

Some people may hate this country, or some people may betray their ancestors and abandon their nation.But Lu Yun is definitely not such a person

He never worships foreigners, he respects his ancestors, he loves his nation, as a Chinese, he is willing to fight for the strength of the nation
