There are multiple models of the silencer designed by Li An, and the effect is also different, but I am not sure which model is easy to use, so I have designed a few more, so that after finally determining which model is easy to use, which one to use Model.

The principle of the muffler is very simple. It looks like a cylindrical iron barrel on the surface, but the internal structure is a bit particular, not straight, but has a certain concave and convex structure, in order to eliminate the fire Strong noise.

To put it simpler, it is to break down the huge noise that is emitted when the gun is fired. In this way, the sound is reduced invisibly, but completely eliminating the sound is impossible. Anyway, it will produce noise. Reduced to a minimum, and absolutely can not completely eliminate the noise.

Of course, in addition to the use of silencers on guns, silencers can be used on many machines in life, in order to reduce noise and prevent noise from affecting others.

There are also types of mufflers, mainly including 6 types, namely, resistance muffler, resistance muffler, impedance compound muffler, micro-perforated plate muffler, small hole muffler and active muffler.

Among them, the muffler used for guns is generally a resistive muffler, which mainly uses porous sound-absorbing materials to reduce noise. The sound-absorbing material is fixed on the inner wall of the air flow channel or arranged in the pipe in a certain way to form a resistive silencer. When the sound wave enters the resistive silencer, part of the sound energy is rubbed in the pores of the porous material and converted into thermal energy to dissipate, so that the sound wave passing through the silencer is weakened.

Li An installed the muffler on the muzzle. Then, he took the whole gun in his hand and put it on the pad. It was still quite weighty. Some of the firearms were handsome enough to hold in his hand.

In addition to the special configuration of the silencer, this gun is also equipped with an 8x optical sight. In this way, the accuracy of use is higher, and it is not a problem to hit targets other than several hundred meters.

After installing the optical sight in place, holding it in your hand, it feels like a real sniper rifle, a sniper rifle that can kill the enemy at a long distance.

Now that the firearms have been designed and manufactured, there is no shortage of ammunition. Li An specializes in the production and manufacture of bullets. Of course, the output is relatively small, only a few 100 rounds.

There are a lot of metal materials for making bullets in the Research & Development Center, and there is no need to worry at all, but gunpowder is strictly controlled by the Imperial Court, and it is generally not easy to obtain, but this is difficult for Li An. After all, gunpowder It was Li An who invented that he could make a small amount of gunpowder at home alone, and then just hand the gunpowder to the craftsman who made the bullet. As long as the craftsman is strictly required to pay attention to safety and keep secrets, quietly produce small Bullets, it ’s stress-free, because in this era, I do n’t know what Dao Child plays for such a small guy, what is the purpose of it, even if it is discovered by intentional people, it is helpless, it is estimated that it is Thousands of Miles Sound Transmission Project Part?

The inequality of knowledge is the main reason why Li An surpasses everyone. In many fields, Li An is a god-like existence, which can conceal everyone’s eyes casually.

At this moment, the guns are already available, and the number of bullets is enough to use. The next stage is the happy play stage. Tomorrow has already made an appointment with the Li Yu 3 people. To go hunting outside the city, Li An believes in his new weapon , Must be able to shine.

However, Li An still does not want to let Li Yu know the existence of advanced weapons such as firearms, so how to deceive Li Yu and let them not find firearms is Li An ’s first consideration.

“Don’t want to, try the gun first!”

Li An pressed a bullet into the firearm and then aimed at the special target in the office. In fact, it was a very simple iron plate with a thickness of 2 cm, which is absolutely impenetrable for ordinary guns. In addition, in order to prevent The bullets flew around and wounded people. On the front and back sides of the thick iron plates, wooden boards with a thickness of ten centimeters were inlaid.

This wooden board can be disassembled, and it is not tightly attached to the iron plate. Even if the iron plate is deformed, it will not affect the normal removal of the wooden plate.

When Li An let the craftsman come up with this target, the craftsman would naturally ask curiously what this is for, and Li An would not tell the craftsman naturally, just make up a reason and be able to deceive the craftsman for a while. of.

After the bullet was loaded, Li An took a general aim, and then fired decisively.

“pa ……”

Because the muffler is used, the sound when shooting is relatively small, and it is not much different from the sound of knocking on the door. It is estimated that soldiers standing outside the office may not be able to hear.

The bullet successfully focused on the target, and the gun was not damaged. Li An got up to check the situation after the target was hit.

The wooden board in the front has been completely penetrated, and even a large hole has been twisted out at the end, and the iron plate in the middle is only sunken. Not at all suffered a lot of damage. After all, the formidable power of the gun is still Limited, for a 2 cm iron plate, that’s a trivial matter, and the wooden board behind is naturally intact.

Li An can already estimate the formidable power of the bullet by looking at the board in front of him. Although it is not particularly powerful, it is at least much stronger than the bow and arrow. It is far from the weapon of this level of craftsmen.

After cleaning the bullets and the bad wooden board, Li An is ready to go back. The office space is too small. If you want to completely let go of the firearms, you must go to a more open place. The large backyard in your house is very In a good environment, Li An decided to go back first, and then play with this newly-built gun in the large backyard.

In order to prevent others from seeing this strange guy, Li An disassembled all the major parts of the gun, so that it can be placed in any bag, without worrying about being discovered, you can hide yourself well. New weapon.

After returning to the government, the first thing Li An did first was to quietly hide the guns and bullets, and then to facilitate the family to eat together.

“You have a good meal and rest, I still have something to do.”

Li An gave an explanation and returned to the house. He went to the backyard with the gun parts.

The space here is large enough, but in order to prevent people from being peeped, Li An chose the location of the experiment to the side of the most side, and let multiple people handle at each exit of the large backyard, let no one No one can enter the large backyard.

Because the location of the practice gun has been selected in the large backyard, there are naturally many targets prepared here. However, unlike the target in the office, the target here is an ordinary arrow target, which is a thin layer. The wooden board material cannot block the bullet.

But there is no need to worry about the bullets flying at random, because there is a special earth wall in the experiment place, the thickness of the earth wall is more than one foot, and the firearm designed and manufactured by Li An is absolutely impossible to put such a thick earth wall It is impossible to break down.

The height and width of the soil wall are not small, the height is about one foot, and the width is 30 feet, so that even if the bullet is very biased, it will not fly out unless Li An shoots blindly. The bullet may be ejected.

Li An took ten targets in one breath, placed them all in front of the earth wall, and arranged them at equal intervals. After that, you can practice.

Under normal circumstances, when firearms are fired, they must be on the ground. The shooting is the most stable and the precision is the highest, but it is always too dirty on the ground. As long as it is not a as last resort, Li An does not want to lie on the ground. Hunting on the ground, so, even if many prey are hunted, but the whole body is dirty, it is too ugly.

Li An needs to practice vertical shooting, so that he has the most face, when hunting, he even has to practice shooting immediately.

The number of bullets is not a lot, only a few 100 rounds, but for Li An practice and tomorrow’s hunting, that is enough. To adapt to the performance of the gun, Li An decided to shoot at least 50 rounds and play with the gun first When you are familiar with it, you will be able to hunt better tomorrow. With an archer’s foundation, Li An believes that his Spear Art will certainly be able to practice very well.

Li An keeps thinking about how to practice the Spear Art by the divine spear hands of later generations. Then, he also does this according to this, aiming, loading, and finally aiming at the target for firing.

Because it is necessary to avoid affecting the 4 neighbors, the muffler is always installed on the muzzle, and the firing bullet not at all makes a loud noise, even Li An himself does not hear very loudly.

At the beginning of the firing, Li An still felt a little uncomfortable, and after using it for a period of time, Li An became more and more proficient in firearm performance, and the accuracy of shooting was getting higher and higher, almost all reached After 100 rounds and 100 rounds, even Li An felt a little surprised.

In a small one hour effort, Li An spoiled 50 rounds of bullets, but the harvest was not small. His Spear Art was greatly improved. A mouse was killed at a distance of 100 metres. That is with no difficulty things.

With such a powerful Spear Art, going to hunt outside the city tomorrow, such as being able to shine, made Li Yu stunned.

After practicing Spear Art, Li An removed the muffler, scope, and stock of the gun, and then put it in a leather bag. After removing a few big guys, the length of the gun was not much. Anyway, it won’t attract great attention from outsiders.

Because it is a big treasure that he likes very much, Li An puts a leather bag with a gun under the bed where he sleeps to prevent his family from accidentally discovering it.

“Husband, are you tired today?”

Yan Ruyu ran over and asked, his expression very emotional.

Li An knows that Yan Ruyu has n’t been favored for many days. Some of them ca n’t hold back anymore, but it ’s sorry, so it ’s more obscure.

Although he was busy practicing Spear Art, it was a little tired, but Li An’s body has always been strong. Such a little fatigue will not be tired after a little rest. The ability to spoil Wife is more than enough.

“It’s okay, I heard Wife recently learned a few tianzhu dances, just show me.”

Li An reclined on the couch with one hand on his head, said with a smile.

Yan Ruyu smiled, nodded and said: “Ruyu didn’t learn well, Husband shouldn’t make fun of others.”

“No, Ruyu devastatingly beautiful, it looks good just a few twists.”

Li An laughed and praised.

“Husband, Tianzhu Dance can’t wear too much, it’s the most wonderful to wear a layer of tulle, but this day is too cold, you need to close the doors and windows.”

Yan Ruyu said, ran to close the doors and windows.

Because it has entered the winter, Li An ’s residence, all the Owner and servant ’s rooms have begun to enter the heating stage, the fireplace has already been used, the room is not very cold, but it must wear cotton clothes It is absolutely impossible to wear a single garment, but as long as the doors and windows are closed and a short dance in the room, the problem should not be big. After all, dancing is also a sport, and the body will not be cold.

“If it’s cold, it’s good to wear more jumps. Don’t freeze 10000000.”

Li An said with concern.

Although watching dancing is very comfortable, if you let your wife freeze, then Li An can’t bear it.

However, Yan Ruyu didn’t seem to care. She gently removed her coat and revealed the light purple autumn dress. This dress was designed by Li An. It was very beautiful and very sexy.

“Wife doesn’t have to take it off again, it’s not good to freeze, so that’s enough, enough.”

Li An prevents Yan Ruyu from continuing to undress. After all, it is winter now, even indoors, it is still better to wear more.

After Yan Ruyu took off his coat, he did feel some coldness. After listening to Li An’s saying, he no longer continued to take off his clothes, so he wore a light purple autumn dress. In front of Li An’s couch, a dancing lightly and gracefully came. .

Because the practice time is not very long, Yan Ruyu’s dance skills are very general, and many places are not satisfactory, but Yan Ruyu’s figure has never been out of shape, and the appearance is also delicate enough, so even if the dance pose Not very in place, but also very fascinating to Li An, and the more irregular the jump, the more charming it is, which makes Li An look very comfortable.

Dancing can also be regarded as a vigorous exercise. After a while, Yan Ruyu is already dripping with sweat, and the thin autumn clothes can no longer be worn. Directly a skilled action, the autumn clothes are gently removed. , Gently flicked, hit Li An’s face impartially.

Li An took a few breaths and smelled the fragrance, and then gently pulled the Qiu Yi down, drunk looking towards Yan Ruyu in a pale pink hoodie.

The pale pink blame and white skin complement each other, plus the dancing lightly and gracefully gesture, this scene is really beautiful, it is inevitable to be intoxicated.

“Hahaha! Wife’s butt is too high, the waist is twisted too much, and the jump is too fast, hahaha!”

After Li An watched it for a while, he started saying said with a smile.
