In the big city of Shanghai in the East, the superpower display competition is unprecedented, and superpowers have been studied by various institutions in the past few decades. Now it is shown to the public through the TV screen, so that the mystery of superpowers in society is slowly revealed.

However, the impact of this contest on human society is not only to unveil the veil, but also to be crowned king.

It's like the first industrial fair. Most countries in the world have seen the power of machinery, and when machinery is no longer covered with mysteries such as Mohist tricks, everyone begins to realize what is the trend of the times? The Industrial Fair is a grand event that crowns industrial science in front of mankind all over the world.

Before the Industrial Fair, agricultural countries and industrial countries like Britain were all in the same position in people's minds, but the characteristics were different, Britain's characteristics were industry, and China's characteristics were tea, silk, and porcelain. People don't understand what industry means, and they understand that Britain, which develops industry, puts Britain in a parallel position with other countries.

At that time, everyone looked at Britain and China like they looked at dwarven musketeers and elven archers. The two units with different characteristics seem to have their own merits. However, as the times gradually pointed out that industry was the next trend in human development.

The scene of industry being the crown and England being the lord of the earth appeared, at the height of Victoria's heyday. The British proudly say: "The Indians grow us cotton, the Chinese grow tea for us, the Brazilians grow coffee beans for us, and the Americans grow grain for us." ”

At that time, Britain looked like the master of the world. And the crown is industrialization.

And now it's a similar thing, when they understand the superpowers, and understand the so-called power of the superpowers in this world to pry into the rules of physics, all human beings have to accept a fact. It will no longer be possible for people's eyes to put superpowers and ordinary people in the same position.

Just like after the industrial fair and a series of colonial wars, the industrial and agricultural countries are no longer countries with each other's characteristics and equals in the eyes of the world. The nineteenth century proved that industry was not an optional subject for a great power, but a compulsory course for every country to become strong.

And now it has been proven that it is not the same thing for a person to have superpowers and not to have superpowers. Although the superpower manifestation induced by humans did not have a strong impact on society, society began to take the initiative to back down and reserved a large number of places for superpowers. The era of superpowers and ordinary people making friends on an equal footing is coming to an end. The gap between the upper and lower positions is likely to emerge in the future.

"What will this society look like?" If this question were asked to Lu An, Lu An would "cut" to say that he didn't care.

"It's none of your business." This is Lu An's attitude at this time. In addition to saving himself, Lu Anshang did not feel that he was capable of saving others. Of course, I don't have time to hurt others and cause trouble.

In the wide training ground, a steel piece of 0.1 millimeter hangs in the middle of the field. Then an air# gun bullet hit this interface. The gas # gun bullet hit the corner of the steel plate, but the steel plate did not reverse in place. Instead, it just slapped the air behind it at a slight angle.

This is also one of the characteristics of Lu'an's super energy, if the object is completely covered by an unimpeded surface, it is impossible to be broken down, and the impulse will be divided into two parts, one perpendicular to the surface and one parallel to the surface. The impulse parallel to the surface is, of course, directly flying away with the debris generated by the impact (it can be seen as a stream of water hitting the rock, turning into countless water droplets and sliding away), while the impulse perpendicular to the surface is partly transmitted to the object after impact, causing the object to bounce away in the opposite direction from which it came, and the other part of the impulse is transmitted to the air behind the surface.

To put it simply, if Luan covers the unobstructed surface on the air directly in front of him. When a bullet hits head-on, an absolutely elastic collision occurs, and the bullet bounces back with the remaining impulse, and the surface transmits the impulse to the air behind, forming a large air flow. mv1=mv2+mv3。 This is the principle of conservation of impulse. MV1 is the impulse of the bullet when it comes, MV2 is the impulse of the bullet that bounces back, and MV3 is the impulse of the air behind the surface. Of course, according to Mv=ft, the thing behind the unimpeded surface is compressible air, and the bullet is in contact with the surface for a longer time, and the force released is relatively gentle.

A bullet of 500 meters per second is very terrifying, but the air flow of a few hundred meters per second, if it rushes in the air for less than a few meters, it will become a chaotic turbulence of the muzzle and collapse. For example, if the shell in the barrel is not released, only the kinetic energy of the explosion of the # charge is not transmitted to the shell, and these high-kinetic energy airflow out of the muzzle, it becomes turbulent under the air resistance, and only when the kinetic energy is transferred to the shell in the chamber, the shell can carry kinetic energy, pass through the atmosphere of thousands of meters, and hit the target.

Theoretically, as long as Lu An arranged a non-resistance plane in advance twenty meters away, the kinetic energy of the bullet would be blocked and turned into a high-speed air flow. Bullets are not lethal.

However, the theory is an ideal state, just like the bald US military units can theoretically fight the combat power of the US army in World War II, but in fact, the industry cannot meet the ammunition and oil, the country cannot meet the food and drink, and the system cannot guarantee morale.

With a whistle, Luan's training was stopped, and more than forty values were recorded on the counter next to him. This includes the speed at which the interface is built. How smooth the interface is after covering the object. The overall evaluation is level 2.

Examiner's comments: It is recommended to carry a folding thin shield to enhance the ability to play.

Lu An looked at the comments from outsiders, took a breath, sat down towards the resting position, and commented on himself after sitting down.

In the public test, Lu Ann arranged his unimpeded surface in detail on the existing steel surface. When the bullet is in contact with the plate, the impulse is transmitted as much as possible to a wide surface, rather than a point. If the force acts on one point, it is easy to be broken, if it acts on one surface, it is not easy to be broken through, just like a punch on a shield, the shield will not break, but a dagger poked on the shield, the shield will break.

Lu An showed the ability to block bullets with a probability as long as a thin steel plate. Because the kinetic energy of the bullet was replaced by a rubber sledgehammer strike with the same kinetic energy. This is the reason why outsiders commented on themselves to carry a thin fiberglass shield to enhance their ability to play.

In fact, Luan can do better, first of all, the unobstructed surface is perfectly covered in an area. The second is a rehearsal, a rehearsal to dodge the bullet, a rehearsal to observe the bullet through which steel plate, and finally in reality, the unimpeded surface is arranged in advance at the position where the steel plate and the unimpeded surface collide.

In the rehearsal, Lu An saw that if he did this, the projectile would bounce off completely. If this ability is rehearsed and supplemented by other superpowers, the effect is very amazing.

Luan sat down and judged his shortcomings:

"Problem one is four meters away, if there is no normal natural interface (water surface, ground, interface of solid matter, liquid matter. It will be difficult for me to accurately lay out the continuous unimpeded surfaces, which will have an infinite number of discrete points. In the face of penetrating attacks, the unobstructed surface of the shattered surface is not well defended.

The response method is to go to the area in advance through the rehearsal to observe, remember the situation in the area, and smooth the layout of the unobstructed surface in reality. Defects, it takes time to walk, and in the rain of guns on the battlefield, even if it is a rehearsal, it is impossible to walk with the target area. Because you will be killed in the rehearsal, you will not be able to walk to the target area.

The absolute arrangement of the unobstructed surface in the air is four meters.

Problem 2: The unimpeded surface reconstruction speed is within 0.2 seconds, and if the enemy's firepower is stronger than this frequency, the defense will be breached.

Solution 1: Increase the super energy level, if you can arrange dozens of square meters of unobstructed surface. Cover your area completely. There is no need to think about the rapid placement of impedance surfaces.

Countermeasure 2: Preemptive strategy, cover the projectile without obstruction, and knock out the target first.

Question 3......"

When Lu An was listing the flaws to himself one by one. The Mighty Assemblies have come to an end. The three divisions of Xuanniao, Dragon, and Tiger all dispatched their own great abilities (level 4) to conduct a "friendly" exchange. The atmosphere of the three parties is becoming more and more eerie.

The purpose of this extravaganza of superpowers is to find someone, which is the main purpose. The event was in full swing, but the Lord did not come. So even if the three superpowers compete with each other, it is meaningless for people at the top.

In some people's opinion, the days have been added to one of the three parties, and one of them, after getting the days, did not let the days appear. That's why the superpower conference came to an end, but the days didn't show up.

In Pudong City, in the building where the Xuanniao Department temporarily stayed, Sun Bai explained to the nineteen-year-old boy Lu Jiuzhong with a nervous face: "The days are here. According to the test, the source of the fluctuation has moved here. ”

Lu Jiuzhong, who was huddled on the sofa and playing with his mobile phone, took his eyes off the interface of the mobile phone, glanced at Sun Bai and said, "Ah, oh, you continue." Then you quickly stared at the interface, and your fingers slid quickly.

Seeing Lu Jiuzhong's appearance, Sun Bai didn't dare to have any dissatisfaction, but said respectfully: "The Tiger Department is the most suspicious, and they are likely to have gotten the number of days." ”

"" Lu Jiuzhong put down his phone suddenly, and a trace of anger flashed on his face, which startled Sun Bai.

I saw that on Lu Jiuzhong's mobile phone, gray and white appeared, just now, in the mobile game world, Lu Jiuzhong was chasing a red-blooded enemy. As a result, the path was a bush, and he was frozen by a skill, and then the red-blooded turned back and killed the character controlled by Lu Jiuzhong in the game.

The fifth-level god is invincible in reality and is still killed in the game. And it seems that because the skin he bought is better, he has been targeted by the alliance of haters of the rich.

Lu Jiuzhong, who was full of anger, almost didn't smash the phone. And the loss of the game finally made his attention divert his attention, he raised his head completely and said in a playful tone: "The Tiger Department has got the number of days, are we going to war with the Tiger Department?" ”

Lu Jiuzhong, who advocates reducing ten meetings with one force, doesn't think it's a big deal to have days. Lu Jiuzhong's absent-minded attitude, Sun Bai understood in seconds, and after thinking about it for less than a second, he felt that he had a different way of expression.

Sun Bai didn't want the Xuanniao Department and the Tiger Department to go to war, after all, the strength of the Tiger Department was slightly stronger than the Xuanniao Department. But his boss didn't pay attention to the number of days, and Sun Bai felt that the project he had worked hard for several years was a precursor to falling short.

Sun Bai explained: "It's not a war, but to seek cooperation with the Tiger Ministry, and if they don't cooperate, we can only unite with the Dragon Ministry." ”

Lu Jiuzhong saw that the character on his mobile phone was resurrected in the spring water base, waved his hand to Sun Bai and said, "You can watch it." Just tell them that if they don't hand over the days, I'll come to the door and ask for a cup of tea. ”

Looking at Lu Jiuzhong, who was addicted to mobile games, Sun Bai said: "Thank you for your support. Then he slowly left Lu Jiuzhong's room.

Ten minutes later, Lu Jiuzhong finished the game, rubbed his eyes, looked at the ceiling and said, "Days? Timid ground rats. Well, whatever. Relatively speaking, I am a little more interested in the other person. ”
