There are actually three very critical problems to solve in creating an air shield for the supernatural by means of technology.

First, how to make air molecules move at a very high speed in a very short time and distance, forming a strong enough force to resist external attacks.

Second, how to make air molecules oscillate back and forth at a certain distance, instead of blowing in one direction like a hair dryer. Because if it is just a single blow, with the air shield can resist the terrifying wind speed of the bullet, the air behind the air shield may be drained in an instant. Maybe even the people behind the air shield will be pumped out. Then it is not to defend against enemy attacks, but to commit suicide.

The third is how to reduce the energy consumption of the air shield to an acceptable range.

Experts at Shenwuguan predict that under the current technology, if the wind speed is to reach a level that can blow bullets away, the energy consumption required is very terrifying.

At that time, I am afraid that even a single air shield will have to be equipped with a battery the size of a car to maintain the operation of the air bomb, which will be meaningless. It's better to bring a bulletproof shield that is a little stronger!

But listening to Chen Yuan's tone, the Iron Fortress seems to have solved the energy consumption problem of the air shield.

This suddenly surprised Qin Cheng.

Because once this problem is solved, then the air shield already has a practical basis! At least you don't have to worry about carrying a huge battery on your body when you have to equip an air shield in the future!

At this time, Chen Yuan also nodded and said, "Yes." We have been able to move air molecules quickly with a relatively small amount of energy, to the point where they can block bullet attacks. ”

He made an analogy: "In the past, our electric cars could make such a heavy car move quickly with a small amount of electricity. There's no reason to just drive that light air and consume more energy than we can handle. And if you really need that much energy, the body of the person with the ability can't bear it. Therefore, as long as the method is used, the energy consumption of the air shield can be controlled within an acceptable range. ”

Hearing this, Qin Cheng's eyes suddenly lit up, and he felt that there was a door, so he hurriedly asked, "What kind of range can you control the energy consumption of the air shield to?" ”

Chen Yuan pointed to the sample in Qin Cheng's hand and said, "What you are holding in your hand is a sample of an air shield generator. Inside this is a 200,000 mAh rechargeable battery. Our design is to allow such an air shield, under normal energy consumption, to be fully charged once, for at least an hour of continuous or cumulative operation. ”

"Hiss......" Wang Luzhou couldn't help but express doubt and took a breath of surprise, and said, "It's unlikely!" A 200,000 mAh rechargeable battery has only about 0.75 kWh of power. Less than 1 kilowatt of electricity, a kilowatt light bulb or a kilowatt high-power industrial fan, with less than 1 hour, the power is consumed, can make the air shield run for 1 hour? ”

But Chen Yuan nodded confidently and said: "Theoretically, it should be possible, we have measured this aspect." ”

He explains: "On the one hand, because we control the spatial displacement of energy in general, we can let the energy act directly with the air molecules, reducing the consumption in between. On the other hand, within the range of the air shield, due to the high-speed back and forth movement of air molecules, most areas of the space will become a relative vacuum. So there is no resistance for the air molecules to move. It's like a satellite in space that can accelerate to a speed several times faster than a bullet with very little force. So we can keep the power of the air shield in the range of one kilowatt. And ......"

"Wait......"

Chen Yuan wanted to continue, but at this moment, Qin Cheng sensitively discovered something incredible from Chen Yuan's language.

He asked in surprise, "Listen to what you mean, it seems to be this thing" He raised the air shield generator sample in his hand and continued: "It is already possible to make air molecules vibrate back and forth at high frequency to resist external attacks in a relatively small space range, and the energy consumption is still very low?" ”

Qin Cheng's words immediately made Wang Luzhou and Liu Xingshan look at Chen Yuan with curiosity and expectation.

But they were thinking, "This won't happen! How exaggerated is the technological power of the Steel Castle? They have not only solved one key technology, but also solved other key technologies? ”

At this time, Chen Yuan nodded reluctantly a little embarrassed, and then said, "If you say so, this sample can indeed be done." ”

"Poof......

Qin Cheng couldn't help vomiting blood: "Haven't you already developed it, so why do you still say it's a sample, I thought it was just a concept product for decoration!" And what the hell is that embarrassed look on your face, yes, yes, no, no. Is it so difficult to use? ”

Chen Yuan explained with a smile: "Isn't it not completely developed yet!" First of all, the strength of the defense of the sample was not enough, and it could barely withstand the attack of the pistol from a distance of 30 meters. Secondly, and most importantly, at the moment air bombs also need to solve the problem of defending the perimeter. ”

"Defend the perimeter?" Qin Cheng and Wang Luzhou both asked suspiciously.

"It's a matter of the radius of the air shield." He said: "Now the air shield, as long as it is opened, the edge of the shield will continue to extend out. When it expands to a distance of more than ten meters, it will not stop automatically, but will continue until the force of the energy disappears. And if the radius of the air shield is not controlled within 1 meter, there is no way for people to hold the shield vertically. Moreover, such a large air shield greatly increases the energy consumption of the air shield, so that the air shield can only last for 1 minute. Let me show you how. ”

Of course, Qin Cheng couldn't ask for it.

So Chen Yuan took the sample of the air shield from Qin Cheng and walked to the demonstration area, ready to demonstrate to Qin Cheng and them.

The entire demonstration was 40 meters square, and the area was covered with a thin layer of smoke.

I saw Chen Yuan walk to a high platform, raise the sample of the air shield above his head, and then open it.

(This is to prevent the air shield from hitting someone else with a quickly extended edge when activated.) ）

Instantly, the smoke in the demo area suddenly churned, as if something had stirred it.

When everyone looked closely, they could see that the entire smoke was suddenly cut open by a huge piece of transparent glass about two or three centimeters thick.

Hehe, I went to get the certificate today. But don't worry, there's another chapter in a minute.
