After completing the *** test, Bi Lingxiao put away the PSG-1, carried the heavy machine gun mount on his side in front of the window, and still aimed at the begonia tree. The heavy machine gun is not as cumbersome as *** and requires absolute accuracy, all it needs is the rate of fire.

This heavy machine gun is called the Race Electro Gun. The Race Electric Gun, also known as the Maxim Heavy Machine Gun, is the world's first truly successful automatic weapon with ** gas as the energy source. This machine gun uses a short recoil automatic method with a water-cooled barrel and is fed with a canvas cartridge belt with a capacity of 333 rounds and a length of 6.4 meters, the cartridge belt can be continued, the theoretical rate of fire is 600 rounds per minute, it can be fired in single or continuous rounds, and it can also be adjusted to a slow rate of fire of 100 rounds per minute by means of a rate of fire regulator.

In that false past life, the Race Gun can be said to be the ancestor of the heavy machine gun. Because it is the original product, in addition to the epoch-making significance for the war, it can be called a classic machine compared to other machine guns that appeared later. The reason why Bi Lingxiao chose this machine gun is, on the one hand, because as a milestone machine gun, he has a lot of contact in theoretical classes, so he is very familiar with it. Another important aspect is simplicity.

In the end, it is the first in the world, and the structure is many times simpler than other heavy machine guns. He originally knew relatively little about large equipment, and the few that he could remember were very vague, and the Makqin heavy machine gun was already the clearest in his memory. Of course, what he really wanted to do was a heavy machine gun called the M134. This machine gun is called the craziest rotary tube machine gun, with a rate of fire of up to 6,000 rounds per minute, it is the fastest machine gun, and was once known as the Vulcan cannon.

The M134 is an automatic rapid-fire machine gun that requires a motor to actuate it, and the rate of fire is determined by the motor speed, which can obtain any rate of fire up to 6,000 rounds per minute by changing the current size.

There is no power supply in this world, let alone wires, but there are energy stones. With a few changes, the same effect can be achieved by turning the electric drive into an energy drive. However, this kind of heavy machine gun is much more complicated, and the dimensions of some specific parts are still very vague, so he gave it up for the time being, and will study it slowly if he has time in the future.

In any case, there is no need for energy drive, relying on the moment of firing, the machine gun and the barrel are buckled together, using the first gas energy as the power, through a set of organs to open the chamber, the bolt continues to recoil the empty cartridge case out and throw it out of the gun, and then drive the bullet supply mechanism to compress the reentry spring, under the action of the spring force, the bolt pushes the bullet into place and fires again. This way, once the shooting starts, the machine gun can continue firing until the cartridge belt is finished. This kind of operation is simply extremely simple, although the firepower is inferior to the M134 I don't know a few streets, but this is an absolutely devastating blow to the enemy in the era of cold weapons of war.

Aiming the gun at the begonia tree, Bi Lingxiao pressed the firing button on the lower grip. Kaka, just as he heard a clear sound of loading, his ears were instantly covered by the sudden sound of bullets exploding! The incomparably heavy machine gun shook rapidly, and the bullets burst out at a speed that was almost indistinguishable to the naked eye, and all the hundreds of rounds were fired in only an instant.

"Great!"

Looking at the muzzle of the gun that was still emitting white smoke after falling silent, Bi Lingxiao couldn't help but cheer. This speed is more than 600 rounds per minute, which can be said to have reached the limit of the Maxim machine gun! You must know that he has never studied the heavy machine gun carefully, and the first one he built with his vague memory can actually achieve such results, even if he already knows that the previous life was just a dream, he can't help but feel excited at this time.

However, the poor begonia tree was struck by such a burst of strafing, and the thick trunk was already full of bullet holes, and the rough bark was cracked and turned out, because of the distance, not all the bullets hit the trunk. There are fine bullet marks left within a radius of 100 meters around the begonia tree, and you can imagine how terrible the lethality would be if this gun was aimed at a huge army dressed in simple armor and rushing straight up with a knife. No matter how many soldiers you have, you can only be a live target in front of a heavy machine gun!

"It's just that it's too bullet-intensive, and it's very bulky, and the reliability of the canvas belt will be poor when it gets wet. ”

This is the disadvantage of the Maxim machine gun. The enthusiasm for a moment gradually subsided, and Bi Lingxiao reanalyzed the machine gun.

In the blink of an eye, a few hundred rounds of ammunition were consumed, but the barrel was not very hot. This is the benefit of the old machine, the rate of fire is not high, the consumption of the barrel is not large, as long as there is water in the cooling water cylinder, the temperature of the barrel does not exceed 100 ° C. When firing, some water will leak at both ends of the barrel, and the cooling water used is not circulating, it is filled before shooting, and water must be added to the cooling water cylinder at any time during combat. When actually shooting, two or three cartridge belts must be applied before steam escapes. This would be different if it was replaced by the M134, and after such a while, I am afraid that the barrel will smoke.

However, the war does not end instantly, even if it is a Maxim machine gun, the barrel will not be able to support it after high-intensity use. Although it is only an ordinary weapon, it seems that the material requirements are still very high. It seems that the machine can use more high-grade materials *** tubes, and the materials that are not temperature resistant are obviously not suitable for heavy machine guns. In this comparison, the PSG-1 is much simpler, the size of the firepower only depends on the explosive power of the **, of course, the material factor is also a certain factor, but at least it will not require such a terrifying amount of bullets and rare metals as the barrel.

"Brother. ”

Suddenly, a voice came, Bi Lingxiao turned his head and saw Chu Xiaoxiao standing at the door.

"What are you doing, so loud?"

The sudden crackling sound just now startled them all, and Chu Xiaoxiao guessed that Bi Lingxiao might be experimenting with something, so she came over to take a look.

"Hehe, I've tried these two new guys!" Bi Lingxiao was in a very good mood, patting the metallic muslin of the Makqin barrel. These two guns, which were basically experimental guns, unexpectedly made him extremely satisfied. "What about you guys, how are the invitations doing?"

Looking at the people, the mood seemed to be very happy, and Chu Xiaoxiao also smiled. "It's done, so let's take a look if there's nothing to do. ”

"Let's go!"

Polaris was scanning the page in front of him with a pen, and stood up when he saw the person entering.

"It's basically done, Brother Xiao will see if it's suitable. ”

Bi Lingxiao nodded, walked over and looked at the blank paper. On the simple piece of paper, the style of the invitation card is drawn at this time, and there are a few lines next to it, which is exactly the content of the invitation that is intended to be written.

"Very good, inform the disciples below to rub and transcribe according to this style, and let the Seven Star Sect and the Weapon Sect also come to help, is there a list of various sects and families here?"

"We have detailed information here, and we don't have a general list, but the Seven Star Sect and the Weapon Sect should be able to get it. Chu Xiaoxiao said.

"That's no problem, try to distribute it within a few days. Polaris, after you contact the Seven Star Sect, you will go to Heze to help Songlin deal with the problem over there. ”

"What about the materials, what are the materials used for the invitation?" Polaris nodded.

"Silver, all sterling silver. ”

In the following month, all the sects and large and small families in the entire Zhongshan Kingdom received a beautiful invitation made of sterling silver one after another, without any rhetoric on it, just a simple sentence:

Gun Sect Auction, exhibiting goods five kinds of guns, please a certain sect master or faction master or door master or patriarch immediately bring an invitation card to participate in Heze, expired.

"It's really arrogant! This Gun Sect really thinks very highly of itself, what kind of style is it to be so conceited and rhetorical! Your Majesty, the minister thinks that troops should be sent to arrest this little boy surnamed Bi immediately, how can he be so arrogant!"

In the provincial capital, in the magnificent and luxurious palace, an old man holding a silver invitation card stared at the old man with round eyes, pointing to the thing in his hand and scolding angrily.

"The prime minister's words are serious, after all, the Gun Sect is the great sect of Zhongshan, and the big war is about to capture its sect master, if it causes the anger of the Gun Sect, it is not good. On the other side of the hall, a young man in blue armor shook his head.

"It is precisely because the great war is about to be like this! This son is really arrogant, the whole world is not the king's land, how can any demon dominate the territory of my Zhongshan country! We human beings and those demons do not share the sky, and the old minister strongly recommends that this son be killed immediately to boost the people's morale!"

The old man clutched the invitation card tightly, trembling with anger. It's not because of the content of the invitation, even if there is some conceit, it won't make the old prime minister of the two dynasties angry like this.

As early as the beginning of the establishment of the gun gate, the old man was strongly opposed, and demanded that the Emperor Fenghe immediately send troops to exterminate these demons. In fact, the prime minister himself has no grudges with demons, neither has any revenge for taking his wife nor killed his relatives and children, and the family has always lived in peace and happiness, and has not suffered any bloodbath. It's just that this old man has received an old-fashioned education since he was a child, and his personality is very stubborn and traditional, so he can't tolerate demons and celestial beings rampant in the world, so that now he is full of righteous indignation, and he looks as if he has been robbed of his wife.

"The prime minister is really prejudiced against other peoples. The Gun Sect was established less than a year ago, and did not do anything to endanger Zhongshan. What's more, they have a grudge against Dongtu, and the war is imminent, and they can also help us. The young knight was obviously accustomed to the excitement of the old prime minister, in fact, since the end of the Three Realms Ranking War, the first thing the prime minister said every day was to get rid of those foreign clans.

"The general's words are wrong! Demons are cunning by nature, how can you be allowed to find out the clues, and by the time you see that something is wrong, it will be too late, and then those ugly guys will definitely show their true nature and fangs and wreak havoc in the world!" the old prime minister clung to the words, completely out of the center of the auction.

"Prime Minister, even if something like that happens, the Empress will stop it, don't worry about it!" the young general shook his head helplessly, and raised his eyes, the one sitting on it obviously had no intention of reacting.

This conversation has been repeated hundreds of times, and I don't know how His Majesty continued to listen with a blank face.

"The empress can't stop this son, the situation of the sect ranking battle is what the general has seen with his own eyes! Now the whole human world knows the horror of that villain, and the people of the world are all trembling, Your Majesty should send troops to act for Heaven at this time, Your Majesty!" The old prime minister blew his beard and glared at him with an impassioned speech, as if a world war was about to happen.

"I said, Prime Minister, ......."

The young general was really helpless. What is it that makes the people tremble, why did he hear something like "Sect Master Bi is really powerful, he actually single-handedly destroyed the Kun faction!" "That Bi Lingxiao is definitely a genius, he actually reached that level at a young age, and even my wife Yasha was killed!" "It is said that the black unicorn has just come of age, it is really young and promising, how good it would be if I could marry such a person in the future!" ...... And so on and so forth.
