"Miss Elsa, Miss Rachel, please put on your earmuffs, because this new type of gun makes a lot of noise..."


    Murphy, director of the newly established Weapons Research Institute and No. 2 in the rune wizard, handed the two sisters two brand new earmuffs.


    Aisha took the earmuff and looked it over and over.


    The style of the earmuff is very simple. The curved bow is made of two metal wires, and a light yellow ear protector is fixed at both ends. Its material seems to be some kind of resin, which is pressed by a mold. The surface of the ear protector is smooth, and there are beautiful patterns, and the inner side is filled with a layer of sponge.


    This pair of earmuffs is exquisitely made, especially in terms of details. This is the typical "excellence" style of Haichao collar.


    Aisha lifted her hair, gently opened her earmuff and covered her small white ears with ear protectors. The sponge felt soft and comfortable to wear.


    She shakes her head, and instantly feels that the whole world is much quieter. Even the sea breeze whistling over the weapon testing ground seems to be much gentler.


    "Mr. Murphy, is this kind of earmuff produced by the earmuff factory?" Aisha blinked her beautiful big eyes and asked curiously, "I remember the earmuff factory was just set up half a month ago. Did it have products so soon?"


    "Yes, Miss Elsa." Murphy smiles with pride. "As far as I know, all departments in the territory have placed 13 orders to the earmuff factory, with a total quantity of more than 200000 pieces, including 150000 super orders from the Department of Commerce."


    "The order of our weapons research institute is the first one to be delivered. This earmuff in your hand is one of the first batch of earmuffs."


    "Haha, even Mr. Goodall has to be behind us if he wants to get the goods..."


    Elsa and Rachel look at each other and see the same idea in each other''s eyes. Lord, how kind of a wife to the rune magician!


    ………………


    As senior officials familiar with most of the affairs in the territory, the two sisters know the origin of earmuffs in detail.


    The original idea of earmuffs came from Goodall, director of the Department of Commerce.


    Last winter, Goodall once saw the bad luck oyster fishing boat at the dock. He noticed that every member of the crew on the fishing boat covered his ears with a piece of thick fur and fastened them with ropes.


    This strange dress aroused his curiosity.


    After talking with one of the crew members, Goodall learned that their purpose was to protect their ears. If their ears were not covered, they would definitely be red and swollen after freezing in the cold sea wind for several hours. After a long time, their ears would even rot.


    However, although this method is effective, there is also a trouble, that is, when working, the fur is easy to fall off.


    This gave Goodall the idea of making earmuffs.


    In his opinion, earmuffs definitely have a huge market demand, especially in high latitudes where winter is longer. They will certainly be welcomed by people. As long as they can be manufactured, the Haichao chamber of Commerce will produce one more commodity.


    Even though earmuffs are simple in structure and easily imitated by other chambers of Commerce, is Haichao chamber of Commerce afraid of competition?


    Never!


    With the industrial standard of Haichao collar, earmuffs can be made cheap and beautiful. The chamber of Commerce, which can do the job of Haichao collar in the human world, has not yet been born ~ ~


    unfortunately, after the feasibility report, which Goodall worked hard to write, was sent to miss Angela, the girl just glanced at it and threw it aside.


    Girl''s reason is very simple. There are so many projects in the territory nowadays, and each one is more important than earmuffs. Human resources are extremely scarce. How can you spare people to develop this kind of low technology thing for you?


    Go away, Miss Ben has no time to deal with such trifles!


    A few months later, things quietly turned for the better.


    When the Weapons Research Institute began to develop powerful magic weapons, many magic weapons engineers complained that the sound of guns shooting was too noisy. After a whole day''s experiment, their ears were buzzing.


    It wasn''t long before Murphy mentioned it in a monthly report submitted to the Lord and the consul.


    Results after reading the report, the Lord immediately gave instructions to the administrative department to set up an earmuff manufacturing factory as soon as possible to produce a batch of "labor protection articles" for the weapons research institute.


    When Goodall knew about it, an old blood gushed out.


    I worked hard to write the feasibility report, carefully analyzed the market prospect, predicted the sales volume, and especially emphasized that it was a profitable project. I didn''t expect that no one would pay any attention at all.


    Some people just casually said that the project started quickly, and even the research was omitted.


    What''s so special? Is there any reason?


    Although "differential treatment" is a well-known thing in Haichao collar, and we all recognize it, can we not be biased so obviously?


    Anyone who understands the cause and effect of earmuffs once again deeply realizes that rune magicians are the Lord''s true love. Compared with them, other people have to stand aside.………………


    "Marx, it''s time to start..."


    Murphy yelled at a strong man standing in the bunker from a distance.


    The strong man named "Marx" nodded and carried a heavy ammunition box on his back. Then, with a low drink, he lifted a magic gun which was one size larger than the machine gun, pushed his legs on the ground and jumped out of the bunker with a "bang".


    At the moment of landing, Marx pulled the trigger.


    "Hiss..."


    "Hiss..."


    Guns with extremely fast speed, while swallowing two bullet chain, terrible metal storm burst out.


    Yes, you''re right. It''s "two" bullet chains, because it has two barrels.


    This is a double barreled heavy machine gun.


    In fact, double barreled heavy machine guns are nothing new.


    On the earth, many countries have made double barrel heavy machine guns. The German mg14z is one of the more famous ones. Some models even show up in the war, and their performance in actual combat is not bad.


    However, due to the complex structure, low reliability and easy failure of dual barrel heavy machine guns, they can not be equipped on a large scale.


    However, in the foreign world, the application of Rune technology has greatly reduced the number of pure mechanical parts and objectively improved the reliability, which has cleared the way for the batch equipment of double barrel heavy machine guns.


    Torrential rain like bullets fell on a stone wall more than 500 meters away, gnawing out countless potholes on the surface of the stone wall, flying everywhere, and the cracks like cobwebs spread rapidly.


    The impact position of the stone wall, which is nearly half a meter thick, became thinner at the speed visible to the naked eye. Only four or five breaths later, it was shot with a big hole.


    In terms of firepower intensity, the double barreled heavy machine gun is far more than the ordinary heavy machine gun, almost twice as much as the latter.


    The terrible firepower made the two sisters smack their tongues.


    According to the prior planning, Marx first demonstrated the output of the station stake, and then performed the mobile output.


    As he ran forward with a double barreled heavy machine gun, he aimed at a transplanted shrub and fired fiercely.


    "Bang Bang..."


    The bullets of the storm soon cleared the shrubbery, leaving only a few low stumps.


    Aisha, who is very familiar with magic gun, is not only amazed, but also keenly aware that in the process of moving shooting, the muzzle shaking range of double barrel heavy machine gun is even smaller than that of single barrel heavy machine gun.


    This directly leads to the bullet''s more concentrated point of impact and easier control.


    How could that be?


    A question came to Elsa''s mind.


    In principle, the recoil force of the dual barrel heavy machine gun is greater, and the shaking range should be greater


    After destroying the shrubbery, Marx ran another distance and aimed his gun at a tree more than 20 meters high.


    "Bang Bang..."


    Bullets hit the trunk one after another, a gap appeared at the bottom of the trunk, and expanded rapidly, as if an invisible beast was gnawing at the trunk.


    As the diameter of the trunk is less than 3 meters and the target is smaller, the stability of the dual barrel heavy machine gun is more obvious. Aisha found that the number of bullets missed is no more than 13.


    It''s an amazing amount of data. It''s not easy to achieve such a hit rate in mobile shooting.


    If you use a heavy machine gun, you''ll lose more than half of it.


    When the gap increases to half of the diameter of the trunk, the tree can no longer support. With a startling "click" sound, the tree breaks off from the gap and collapses abruptly.


    "Boom!"


    Nearly 200 tons of trees fell heavily on the ground, making a loud noise. The ground suddenly trembled violently, and the dust rose up all over the sky.


    The visual effect of this scene is particularly amazing. Although the trees are more than 600 meters away, the Aisha sisters can''t help but step back.


    Marx ran back with a double barreled heavy machine gun, raised his hand to salute and said in a loud voice:


    "Sir, after the demonstration, please give instructions!"


    Murphy "ha ha" a smile, back to a less standard military salute, said:


    "Marx, hard work, you can go to rest now..."


    Marx nodded, put the gun on the ground and turned away.


    Murphy looked at the Aisha sisters and said with a smile:


    "Miss Aisha, Miss Rachel, as you can see, this is the first magic heavy fire gun developed by the weapons research institute. We call it" double headed snake. "


    "In the war of Qianhu Kingdom, we found that the general heavy machine gun is too light for the awakened to give full play to their strength."


    "so as like as two peas, the Lord of the Lord ordered a special gun for the awakening of the army, so we created a double headed snake, which has the same caliber as the ordinary heavy machine gun, and the two can be combined bullets."


    "The maximum firing rate of the heavy machine gun is 150 rounds, while the double headed snake heavy machine gun has a firing rate of 400 rounds, but its weight has not increased much. It is only 40% higher than the machine gun.""Once the design of the double headed snake is finalized and mass production begins, 80% of the awakes in the army will be equipped with this weapon. We expect that the firepower of the whole island protection team will be more than doubled by then!"


    The twin sister''s pretty face immediately showed the color of exclamation.


    Murphy added:


    "by the way, the double headed snake will also be equipped on the metal biplane" silver kite "to become an airborne weapon..."


    Rachel squatted in front of the double headed snake, reached out to play with the double barreled heavy machine gun, and opened her mouth to ask:


    "Mr. Murphy, although the double headed snake''s firepower is very strong, it can be seen that it is a kind of gun with complex structure, which will bring difficulties for subsequent production."


    "Why doesn''t the weapons research institute develop a single barrel heavy machine gun with a larger caliber? I think large caliber bullets are more powerful, which can make up for the shortage of quantity, and the production difficulty of single tube is lower... "


    After Rachel squats down, the condescending Murphy naturally sees a touch of whiteness on her chest. He jumps to his heart and looks away quickly to hide his embarrassment by speaking.


    "Miss Rachel, you asked a wonderful question."


    "At the beginning, we really planned to develop a heavy machine gun with a diameter of 20 mm, but after some discussion, the LORD rejected this plan because..."


    He accentuated.


    "Logistics!"


    "Every additional caliber of bullets in the army means that several bullet production lines need to be added in the territory, which also means that it will bring greater pressure on logistics management."


    "If different calibre bullets are confused, for example, large calibre machine gun bullets are wrongly allocated to small calibre heavy machine guns, it is very likely to cause disastrous consequences in a fierce war."


    "After that, we decided to develop a dual gun."


    "I see." Rachel suddenly realized, "you have a point. Simplifying logistics is really important."


    Asha notices Murphy''s furtive eyes. She gives Rachel a kick and signals her silly sister to stand up. Then she asks her doubts.


    "Mr. Murphy, in the course of the demonstration just now, I found that the shooting stability of the double headed snake heavy machine gun was surprisingly high. Can you tell me why?"


    Murphy glanced at Elsa in surprise.


    He suddenly found that he seemed to belittle this pretty girl. If he had not had rich experience in using heavy machine guns, he would never have noticed the difference.


    Murphy said with a smile:


    "Miss Elsa, your eyes are admirable. What you call" high stability "is the most important characteristic of double headed snakes."


    Then he laboriously raised the double barrel heavy machine gun, pointed to a long strip-shaped part close to the barrel, with holes on both sides of the part, and said with a kind of praise:


    "this is another amazing invention of Lord, its name is" recoil suppressor ". I think only Lord''s great wisdom can create such a delicate design."


    "We know that the recoil force of magic machine gun comes from the air in the high-pressure air tank. When the high-pressure air pushes the bullet out, it will also produce a reaction force on the gun."


    "The Lord cleverly designed a ''loop'' structure, which led the high-pressure air from two gun barrels into it, changed the flow direction of the air flow, and let the air flow out of the jet holes on both sides of the suppressor."


    The color of admiration in Murphy''s eyes grew stronger.


    "Now the direction of the reaction force is changed, and it is divided into three parts, one part to the left, one part to the right, and one part to the back, and the first two just cancel each other, leaving only the reaction force in the backward direction."


    "After testing, we determined that the recoil force of the double headed snake heavy machine gun is reduced by 90%, which is smaller than that of the ordinary heavy machine gun, so the stability of the double headed snake is better."


    "I think you should know that high stability will bring higher shooting accuracy, which is very important in actual combat..."


    Isaiah nodded silently, her beautiful eyes twinkling, and she didn''t know what she was thinking.


    Murphy glanced at the two sisters, coughed and said:


    "ladies, please move to the No.3 weapons test ground. We have another weapon to show you. It is a weapon specially developed for Yinyuan..."


    "Oh?" Rachel asked, "what''s that weapon? Is it powerful? "


    "Aviation incendiary bomb!" Murphy grinned. "Yes, it''s very powerful. The LORD said that in the coming all-out war, if you want to keep Qianhu Kingdom, this kind of weapon is the key of the key!"
