When the force area is constant, the pressure increases proportionally with the increase of pressure, if the force area is different, the smaller the area, the greater the pressure, and the greater the pressure generated. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The above is a physics concept that any middle school student knows very well, and the truth is so simple and simple that human beings have been using it consciously or unconsciously since time immemorial.

They invented stone knives and arrows to hunt ferocious beasts, they forged swords and spears and used them to kill their fellow human beings on the battlefield, and when mankind came to the age of hot weapons, a series of inventions such as steel-core warheads and length-to-diameter ratio shell-piercing shells also took advantage of this simple truth.

Among the internal force warriors, there is also a group of people who have never forgotten this simple Taoist concept, and they have been pursuing a simple truth in the process of internal force transformation and kinetic energy attack: greater pressure, smaller force area, higher unit pressure, and higher unit pressure, more extreme destruction!

The name of this group of people is called Swordsman! Some people call them Swordsmen, in some worlds they are called Sword Cultivators, and the best of them are called Sword Immortals or Sword Gods! As for the sect that masters this kind of rough truth, it is also called the Sword Sect.

Not all martial artists who hold swords can be called swordsmen, just like a martial arts sect called the sword sect is not called casually, this is something that Xiang Ji learned from the main god and the seniors around him.

A warrior who awakens internal force can instinctively convert the pure energy of internal force into mechanical energy to propel himself and hurt the enemy, and harming the enemy involves a problem of hitting the surface.

Initially, when a warrior throws a punch, the surface of his internal force explosion is an irregular circle, and the area of this circle is larger than his fist; as the warrior becomes more and more proficient in his control of his own internal force, and more and more accurate, the area of this circle will shrink until it finally turns into a clear fist mark, and the area of the circle is exactly the same as the surface area of the fist; as for going further, compressing the area of this fist mark even smaller, becoming smaller than the striking surface of the fist itself, the warriors find that it is very difficult to do.

Because internal force, the product of the combination of the essence of energy and the essence of the soul, is itself limited by the very strength of the human soul. In people's subconscious, the surface area of their fists is so large, and now if you want to make the internal force through the fist compress its striking surface smaller than the fist surface, it will become very difficult and difficult, so difficult that every time you compress a point, you have to pay dozens of times more effort.

So some people find another way, that is, through the weapon in their hands to further reduce the striking surface, after all, through the contact between the body and the weapon, the internal force can also be played from the weapon. And human weapons, especially some sharp weapons, have a much smaller cross-section than their own fists!

It looks like a beautiful idea, but Xiang Ji knows that this is not so easy, it is a high-end technical job, talent, diligence, hard work, and a little luck, everything is necessary to compress the impact surface of the internal force to the right point, to the extent that it is as fine as the thickness of the blade in his hand.

With such a small striking surface, the powerful kinetic energy is concentrated and released in a small area, and the destructive power caused by it is naturally multiplied, and the highly compressed air near the striking surface has become the so-called sword qi in people's mouths.

The sister Lu Xueqi in front of her obviously mastered the sword qi, and it was in this way that she was able to cause enough damage to Xiang Ji's body with her relatively shallow internal force. But if it was just that, Xiang Ji would not be so passive, because thanks to his strong soul strength, he could also compress the striking surface of the internal force very small, even if it was not as good as a professional swordsman like the other party, he would not suffer a big loss.

But Lu Xueqi's little girl is perverted at this point, she can not only use the long sword to shoot sword qi, but also go further, and compress the striking surface of the internal force to a smaller size through her own ability, so small that it is far lower than the size of the blade itself!

Ordinary swords, their blade thickness can reach tenths of a millimeter, even if it is very good, can ensure sufficient cutting force and is not easy to curl. Some famous craftsmen have created magic weapons, the thickness of the blade surface can be thinner, and the cutting force is correspondingly stronger, and at the same time, it can ensure sufficient hardness, and there is no curl or notch under vigorous chopping, but the thickness of the blade is still limited after all.

Therefore, the sword qi generated by using the sword blade as a template, its striking surface is naturally limited by the thickness of the sword blade itself, which means that the striking surface of the sword qi is difficult to become smaller than the sword blade itself, and the further improvement of the power of the sword qi has become a luxury.

So some geniuses came up with a way to transform the internal force into a special form, so that the nature of this internal force is between the pure internal force and the human mental force, and some planes also call this process the fusion of internal force and spiritual force.

Using the precise characteristics of spiritual power, the burst of internal force was concentrated in a very small area, making the striking surface of the sword qi smaller, so small that it was far smaller than the sword blade itself! In the information that Xiang Ji saw, some swordsmen in the high-level supernatural plane could even shrink this striking surface to the nanometer level!

This is the sword intent! Because of the formless and insubstantial nature of the internal force, this almost means that the swordsmen have an invisible sword in their hands that is perfect to the extreme! A super sharp weapon that is difficult to reach with a tangible sword no matter what! It is a super divine weapon that does not curl the blade, constantly folds, and has ultra-high hardness but is extremely sharp!

The sword in the little girl's hand is probably not terrifying enough to cut nanometers, but it also has the rudiments of sword intent in Xiang Ji's perception, and he can sense that the sword qi emitted by the other party is far less than the thickness of the blade itself.

"Little sister, do you know that geniuses are hated. Xiang Ji thought a lot in a short period of time, and finally said such a thing with emotion.

It is indeed envied, even in many medium-sized supernatural planes, the generation of sword intent also means a very rare talent, not to mention that the world where Lu Xueqi is located is almost the lowest level of the supernatural plane.

"I admit it, what you said is not a lie, your sword can indeed kill me, your ability to kill me is too strong, my steel skin and iron bones, my mountain pulling skill and my internal force defense are difficult to resist it, you are really a genius!" Xiang Ji did not hesitate to praise.

"My ability? Do you mean my ability to use a sword? Listen to what you said, it is the legendary sword intent?" Lu Xueqi asked, holding the long sword.

"That's right, a terrifying ability that can do 10,000 things with one point. Because of this, it is enough for your level of internal strength to hurt me, or even kill me. Your words are indeed not bragging, I now understand the meaning of Mr. Lu sending you up, this is indeed the last hole card of your Lujiazhuang. “

"So that Your Excellency may know that this granddaughter of mine has always been very talented in the way of the sword, and her sword can be said to be almost indestructible. But Your Excellency's strength is too amazing, and I'm not sure if Xue Qi can break through your defenses at all, so I didn't ask you to take out your weapon, please forgive me!" Lu Qingfeng on the side said with some apologies.

"Since you have said so, big brother, can we tell the winner of this competition?

"yes, let's settle it as a tie. Lu Qingshan also opened his mouth to persuade, hoping that Xiang Ji would give up the competition, and if he could retreat, it would be better. In the end, he is still very jealous of the so-called Inhuman Valley behind the item, and he doesn't want to make any more troubles if he can solve the problem like this.

"The owner of the village doesn't have to apologize, it's not your obligation to remind me, it's originally my own business, and even if the ordinary weapon is taken out, I know it, how can I stop a swordsman with sword intent?" Xiang Ji shook his head.

"However, I do have a weapon in my hand, which should be able to block my little sister's sword aura。。。。。 “

Lu Qingshan said this, they were nervous for a while, they knew that their granddaughter's sword had been sharp since she was a child, and the sword was indestructible in her hands, and her body was also very fast, so fast that she surpassed Lu Qingshan, who was the number one master of the family, so they would take the risk of sending her up to try it when they had to do it, and they didn't expect that the effect would be so good.

But if he loses the advantage of invincibility, in the face of Xiang Ji's terrifying power, there will be no advantage at all, and for a while, Lu Qingshan's hearts are in their throats, staring at Xiang Ji's body tightly, for fear that he will pull out a magic weapon from somewhere.

"Well, it's a pity I didn't have that weapon with me today。。。。。 Xiang Ji also saw their expressions, showed a wicked smile, and told a small lie to the people in Lujiazhuang.

Nima! If you speak loudly, can't you finish it in one breath? I don't know if it will scare people to death? Lu Qingshan secretly cursed in his heart.

"So, I'd better go empty-handed, let's continue, I won't necessarily lose this time. Xiang Ji had already thought of a way, he didn't want to use the cold iron spear to defeat the little genius in front of him, that was already equivalent to admitting defeat and surrendering, even if the other party had a terrifying and powerful talent.

"When the eldest brother said this, I could only accompany him. Lu Xueqi's sword pointed at Xiang Ji again.
