"When the dark matter field covers the entire earth, a material world that is completely different from the molecular atom material world is in the same space as us, under normal circumstances, the two material worlds do not interfere with each other, but human life individuals can just make the two material worlds meet, and the superpower is the physical phenomenon brought about by the intersection of these two material systems. Your superpowers are a manifestation of the normal rules of physics. Speaking of this, the teacher paused and looked at the students in the stand.

The teacher on the podium put down the laser pointer and glanced at the students in the class, and said with a little emotion: "Having supernatural power is a kind of divine blessing, and this divine blessing should be carefully observed. The power you have directly changes a physical phenomenon, but the rules of physics are interrelated, and when a physical rule is out of balance, the whole edifice of the rules of natural science will collapse, and after the collapse, compromise, you directly affect a physical rule of the atomic, molecular, material world, and at the same time affect all the physical rules. ”

The teacher wanted to continue, The jingle bell rang for the end of class, and Lu Anzai's eyes moved away from the image on the scratch paper, looked at the teacher who left the class, and said silently in his heart: "Yes." It's just that the rules are compromised. ”

In the rehearsal, he fully thought about his personal research on his own unhindered superpower in Yuanyi, and Lu An very much agreed with this teacher's point of view, the superpower phenomenon directly changed a physical phenomenon, and indirectly changed all related physical phenomena.

The so-called physical experiment is to let one physical phenomenon achieve the surrounding conditions, induce another physical phenomenon, and observe its influence. The nuclear bomb experiment is a high-pressure phenomenon of explosive shock wave energy accumulation, which induces the nuclear material to reach a supercritical phenomenon. The chain reaction phenomenon is a physical phenomenon induced by the explosion phenomenon. And all the rules of the world are mutually influential, because they affect each other, so there is no absolute in the true sense.

Luan's ability is actually to wrap an object in a field of thickness, and this field is like a membrane. This field can accept any substance entering, and when the substance enters, the properties change. Mechanical energy, the natural process by which elastic energy is converted into internal energy, slows down to almost zero. It can be approximated to mean that the collision of matter only separates elastically and does not produce internal energy (or that it is difficult for humans to measure internal energy production). That's what unhindered films are all about.

This layer of unhindered film has a very peculiar phenomenon, just in the thickness of this layer of film, any substance that enters this thickness range is compressible, including water, steel, ceramics, can be perfectly elastically compressed, and the impact force will not become disordered molecular movement. Rather, it becomes the elastic energy of the material.

In reality, after any spring is compressed many times, you can feel the spring heat up when you touch the spring. This is the loss of mechanical energy into heat energy in the process of converting into elastic energy. On this membrane, the process of converting mechanical energy into internal energy stops (almost stops), and the impact kinetic energy becomes 100% elastic energy.

At the moment of impact, the material within the membrane is violently squeezed and deformed, and finally breaks through the binding force in the material. The cracked substance gains kinetic energy. Then slide out. This is the reason why the steel balls covered in the film hit the wall and countless powders popped out of the steel balls. So in the end, the kinetic energy of the impact is converted into heat. It's just outside the membrane range.

The thicker the membrane around the projectile, the easier it is to break down. It is easier to compress a rubber rod of one meter by one millimeter than it is to compress a rubber rod of one centimeter by one millimeter. The thicker the membrane around the projectile, the easier it is to squeeze into the material during breakdown contact.

Of course, it is difficult for Lu An to cover the projectile with a thick absolutely elastic unhindered film now, and in the impact at will, the internal energy of the impacted material can eventually be increased, and the kinetic energy of the impacted object is consumed.

Lu An's casually thrown steel balls couldn't penetrate a centimeter or two of steel armor. The steel ball is drilled a hole in the steel plate. The slingshot may not be able to pierce. Bullets can pierce, but not indefinitely. Because when penetrating, the surrounding penetrated material is crushed and the internal energy increases, which is a process of energy absorption.

Most of the process of breaking down rigid materials is accompanied by crushing.

Of course, if the thickness of the membrane is large, the volume of the membrane is much larger than the volume of the projectile wrapped inside. In this way, the material within the membrane will reserve part of the space under the extrusion of the impact force, and in the rigid material, the projectile will break through as if it were in a flexible pipe. But there is no absolute rigid material in the world, even if it is cement, hundreds of meters of reinforced concrete buildings will sway in the wind. Even if the material within the film becomes more flexible and hard, the elastic force will eventually deform the solid material outside the film. Kinetic energy will eventually become heat energy in the deformation of the material.

Only by shuttling through a homogeneous fluid can an approximate resistance-free phenomenon be achieved.

So Lu An understands that the ability he has mastered is just to make the physical resistance rules inherent in this world compromise to the extreme on the goal he has chosen. It's just a compromise, but it still can't reach the absolute.

Having figured this out, Lu An understands his own ability, his ability to have zero resistance, and the theoretical zero resistance gap. In fact, it is like the relationship between the lowest temperature that humans can produce and the theoretical value of absolute zero.

But that's the case.

Lu An's current rating is still problematic, drag reduction and zero resistance (near zero) are two different concepts. Just like air conditioning cooling a room and liquid helium freezing are two different concepts.

If it were the former, the academy's researchers would try to help Luan move in the direction of defense. If it's the latter, the Academy's researchers will turn Lu An into an extremely offensive superpower.

When Lu An was in the public test, he showed a two-square-meter surface with reduced resistance, and a two-square-meter surface with a cement surface, a steel plate surface, and a sticky surface with glue on both sides. After the test, they gave Luan a second-class rating.

If it is drag reduction ability, usage 1: When the blast wave of the explosion is impacted, the resistance of a shield is reduced, which can effectively bounce off the shock wave.

Usage 2: Reducing resistance to the ground can make a lot of people fall.

During the public test, Lu An distributed the non-obstruction film very finely at the convex part of the contact surface (there is no absolute plane in the world). As long as it is a surface, there are always bumps. ) has a lot of drag reduction effect. Subject's assessment of Luan's abilities was: "Very good, but the area of influence is too small." "The training advice given by the experts is to try to find the direction in which the area increases.

If it is a zero-resistance capability. The bullet shot by Lu An is the world's strongest penetrating weapon. Pistol bullets are sniper bullets. If the science and technology department of this world specially equipped Lu An with a set of mechanical aiming equipment. Luan's lethality will be multiplied.

Of course, Lu An understands that his superpower is the most suitable for killing. After the bullet is discharged, it is wrapped in the unobstructed interface together with the gunpowder gas, and the bullet and the high-speed air behind it fly at high speed together without slowing down, and when the bullet hits the target, the unobstructed film is automatically canceled, and at this time, the bullet penetrates the flesh, and the high-pressure and high-temperature air block that does not decelerate after moving hundreds of meters out of the chamber is poured into the wound made by the bullet projectile. It can create a huge cavity effect. The high-pressure air (gun flame) that normally discharges the gun will immediately collapse quickly outside the muzzle due to the action of air resistance. The outer bread has a zero-resistance surface, and it will not collapse. His own ability, Lu An himself knows how to use it. Every night in the Yuanyi space, I keep pondering.

But the question is, why does Lu An want to fight and kill in this world? It's such a dangerous thing to fight and kill, why don't you take the initiative to get involved if you can't hide by yourself? Why do you want to do something that is not beneficial? Lu An couldn't open the pot again. The greatest pursuit is not money, not fame. It's just safety, and the training of the super is to be safe in the mission of Yuan Yi. Don't abandon the safety of the world you live in for the safety of Yuanyi's mission.

Lu An believes that he should be seen as a cultivator with defensive potential at the Abyss Academy. And not offensive geniuses. If there is no defender to cultivate, the cultivation department above will generally not let the defender take risks. But once an offensive genius is shown. God knows where they will be drafted and what kind of dangerous confrontation missions they will take.

Lu An gave himself the nickname of Loach, but he did not give himself the nickname of armor-piercing bullets. With the talent of ADC (Remote Physical Output), disguise yourself as having a future for MT (tank) development. That's what Luan did. It's okay if you don't focus on training. The key is to develop obscenely. Lu An doesn't think that his zero resistance super energy is the top in this world, but according to the urine team battles in the game, they all hit the opposite firepower output first. In real battles, in case you are targeted. That's not to cry to death.

Although the rehearsal can prevent Lu An from being killed by the other side, the current situation of the rehearsal makes Lu An cautious when stepping on an ant, and killing people will definitely change the rehearsal ability. Lu An didn't dare to kill at all. In this case, it is better to not have an ADC than not to take the head.

When the teacher left, Lu An walked out of the classroom according to the rehearsal plan. There was a large crowd in the hallway outside the classroom. Huge CCTV live broadcast shows intense superpower confrontations. Lu An stopped and looked, and these opponents on the screen were all superpowers above level three. In terms of power, handling accuracy, and staying power, it is compared in many aspects.

Now everyone is gathering to watch, and what is being broadcast at this time is because at this time it is a big power (the fourth level is fighting) and the abilities of both sides belong to the category of electromagnetic waves, but the wavelength of electromagnetic waves controlled by the north is in the microwave range. And Chongming City is playing against the fantasy # controller Xia Xingrui.

The battle didn't last long, and after forty-three seconds, Xia Xingrui flashed his opponent's eyes with a strong light and won the victory. So after Lu Ann finished the rehearsal, he chose a staircase and left. If you don't leave, a girl and two teenagers in the crowd will take the initiative to come over to greet Lu An, and now the person who will talk to Lu An in the future is concentrating on watching the unfinished wonderful duel on TV, and it is difficult to walk away. Had to miss this opportunity to say hello to Luan.

This kind of miss is a coincidence, and maybe one will miss it in the future.

Lu An is now a second-level superpower, and he has not joined the forces of any students, which is very rare. Linyuan College is not a prestigious school. There are only fourteen third-level superpowers, and two hundred and thirty-two second-level superpowers. Lu An's second level is a stronger second level. The ability to make the ground slippery and unsteady on the ground is impressive. It's normal for there to be associations that want to absorb.

Loaches are not so easy to catch. Let all the things around you that you don't want to participate in and let the things you bother to slip past you, this kind of character explains why Lu An awakens the unhindered superpower in this world.
