The season has entered autumn, but it has not yet reached the time when the leaves turn yellow and a large number of leaves fall with the wind as soon as the wind blows.

Located in the south of Chang'an, close to the Qinling Mountains, there is a small military camp on the edge of the mountains.

The military camp exists to block the surrounding area. Looking at the complete blockades, and then at the pass leading to the Qinling Mountains, it is not difficult to imagine that there will be facilities that do not want to leak secrets.

"Your Majesty." Holding a rifle in his hand, Zhang Shi introduced: "This rifle is improved on the basis of the twelve styles. The length of the gun body has not changed. The weight has been increased by one catty, and the caliber has been reduced to ten. Four millimeters. Its barrel has been changed to a rifled style and a smooth-bore style. After testing, it has higher accuracy and increased range."

To put it bluntly, it is a rifled gun. In terms of level, it should have reached the level of the mid-15th century.

"The barrel is spiral and straight." Ma Zihuan, an expert, gave a detailed introduction of the results of changes in the barrel structure. Later, he commented: "After repeated tests, the spiral barrel is obviously excellent. In a straight barrel."

Although Liu Yan has passed by for so many years, he has not completely lost all his due attempts at guns.

Of course, the spiral gun management is better than the straight barrel. The spiral barrel can make the long lead shot rotate when the projectile is fired, and the flight is stable after exiting the chamber, which improves the shooting accuracy and increases the range.

There is a machine tool next to everyone. Naturally, it cannot be driven by electricity, but it uses animal power.

The most conspicuous feature of the machine tool is the drilling rod, which itself is a spiral style, and spiral lines will be left in the barrel when drilling.

At the current level of technology, such a machine should be the best hydraulic power, but it is not easy to find a suitable river. It is set as an animal power style and placed in Qinling.

Two or three years ago, there were craftsmen who were able to build rifled gun barrels by hand, but the rate of finished products was not high. Furthermore, there were too few craftsmen who were able to do this. In terms of being a "toy" for a few people, It doesn't matter how low the output is, but as a firearm that needs to be installed, it is too small.

Liu Yan only put forward an idea, and Shaofu made the greatest efforts to research and test, and it took three years to develop the machine tool.

The new machine tool placed in the Qinling factory is currently unique. After trying it can drill up to five barrels in a day, and the yield rate is four barrels. It can be said that the yield rate is already a little scary.

"If it is changed to hydraulic drive, Chen estimates that the efficiency can be increased by about two times." Ma Zihuan already knows what dynamics and what efficiency a machine can exert, generally it is a driving decision: "It takes half a time to make a rifled barrel by hand. In May, Chen deeply felt the gap between manpower and machinery."

There is only one new machine tool, but it does not mean that there is only one machine tool in the country. For example, machine tools were used to build ordinary barrels before. Those machine tools are divided into two types: animal power and hydraulic power.

The previous scientific research results are the basis to ensure the replacement. Any technology has indeed become more advanced from generation to generation. Unless something miracle occurs, otherwise it is impossible to use throwing stones to hit people in the last moment, but in the next moment. It was fired in the "咻咻咻" armed with a Gauss gun.

Accumulation is an inevitable process for science and technology, and that process is actually to understand the elements, and then extend various sciences, and a variety of scientific research results can be combined to form a product.

"This rifle was named'Twelve-Type Modification'." Liu Yan took the rifle, and on the whole, it didn't change much. Compared with a shooting posture with a gun: "The farthest range is 920 meters. ?"

"His Majesty, yes." Zhang Shijing said reservedly: "The precise shooting distance reaches 280 meters."

Liu Yan remembers that the appearance of rifled guns has changed the way of shooting at platoons. Soldiers holding rifled guns are no longer arranged in a close formation. They are formed into an array of skirmishers to take advantage of their range instead of firing close to each other. , Is a method of retreating after repeated shooting until the opponent can shoot to the distance of oneself.

Liu Yan, the first soldier who made a soldier holding a rifled gun into a sniper role, has forgotten. After the first one did that, the war in the age of firearms entered a new mode. After the commander was repeatedly sniped, never again. No commander is stupid looking for death.

"Your Majesty." Zhang Shi asked kindly: "Do you want the minister to bring gunpowder?"

Liu Yan also really wanted to shoot and see in person, came to the shooting range to skillfully reload, and then made a standard gun-holding posture and aimed at the gun target 100 meters away. When he pulled the trigger, his body felt recoil, and there was a "pop" sound from his ear.

In the distance, a raised target made a "puff" when the projectile hit, and the dust and smoke were quickly blown away by the wind.

Someone brought the target. The hole in the center of the target ring showed that Liu Yan had shot accurately, and also proved that this twelve-type modification can be used as a sniper rifle.

"Try one hundred and fifty meters." After Liu Yan cleared the barrel, he was working on reloading again: "Maybe the **** of this gun should be changed, slightly longer by about three centimeters?"

The person holding the notebook next to him took the record immediately.

What's the use of a gun with just three centimeter changes? That's a question that people who don't know how to do it.

Not to mention firearms, even a war knife, a little bit of change will produce a different feel.

The length or the shortness of the firearm, and even the weight of the firearm, reaches the most reasonable design, the more powerful it can be exerted.

The feel of holding a gun is very important to the shooter. Even if it is only a little more comfortable when holding the gun, the different thoughts and feelings are more reasonable in the posture, and every shot can be more accurate.

Otherwise, there is no need to distinguish between standard equipment and customized equipment, such as modern sports, who will use standard equipment, all of which cost a lot of money to customize.

After Liu Yan had loaded his ammunition, he once again became the standard gun-holding posture, but he maintained the aiming action longer than the previous one. Not only was the aiming at three points and one line, but he was also observing the plants around the gun target.

Whether a firearm is accurate, not only considers the firearm itself, but also tests the gun holder. At least it should be understood that the wind direction and wind force are also one of the factors that can be accurate.

Liu Yan was observing the plants around the wall to determine the wind direction and wind force. When aiming, he adjusted the aiming device so that the three points and one line changed.

The adjustment of gun parts is a very professional move, such as aiming at a 100-meter target and aiming at a 200-meter target. The aiming device must be slightly adjusted, and the wind force needs to be adjusted accordingly, or else it is It would be the standard to shoot a 100-meter target, but the same three-point, one-line shooting to a 200-meter target was far too close.

Although the standard device of the Twelve-Type Modification is an adjustable mode, it does not have a professional scale. It still requires the user to have sufficient knowledge and common sense (proficiency). Regardless of just adding a scale, it is just such a small part, and the time it takes is definitely not short with the current level of technology.

With a knock, Liu Yan's body swayed backwards, and his brow furrowed after the shot.

After the gun target was brought over, the hit position was within the seven-ring circle. Although Liu Yan frowned just now, he did not hesitate to admire the rifle.

Inaccurate shooting is not only a problem of the quality of the guns, but also a shooter's reason. Liu Yan will not use his own mistakes to deny the quality of the guns.

Liu Yan was obviously not a person who gave up after an unsuccessful experience. After that, he shot twice and stopped the test after he hit the tenth ring.

There are professional test shooting personnel at the shooting range. They have been waiting by the side. Seeing that Liu Yan can hit the tenth ring with only three shots, they showed an expression of admiration whether or not they pretended to be.

After the three test shots, the test shots were carried out in turn, fifty meters, one hundred meters, one hundred and fifty meters, two hundred meters, two hundred and fifty meters, and three hundred meters. The farther away the target, the lower the accuracy. With a total of 30 shots, the best result was to hit the third ring of the target at 300 meters, and to a large extent it was luck.

After the test firing is completed, the test firing personnel will evaluate the firearms in a professional direction, and the recorders will record them one by one, all in an effort to do the best.

Evaluations and records were made there, and the military generals who came with them lined up to test the shots, which seemed to have a great time.

"It's very good." Liu Yan said with a smile on his face to the general who watched the whole process and shot himself: "A good shooter should be selected to use this weapon exclusively."

"Your Majesty, Shengming." Huan Wen just tested a target with a range of 50 meters to 200 meters. Although he has not hit ten rings, his results are not too bad: "It is a model that can kill the enemy on the battlefield. The weapon among the Hosts."

Ran Min didn't play with firearms less. He just fired a few times, and the worst score within 200 meters was also hitting the eighth ring: "I thought that the flintlock was powerful enough, but I didn't expect that the accuracy of the gun would be so terrible just by changing the barrel."

The emergence of firearms will definitely change the way of warfare. The simplest is that the value of force is reduced. A master who has been practicing for decades will die if he is shot, and people who do not understand any fighting skills will be shot. Will die, and the value of working hard to practice fighting skills will become a meaningless thing.

Seeing the bitterness on Ran Min's face, Xu Zheng didn't want to comfort him at all.

For a fierce general like Ran Min, with the change of the form of war, pure bravery has little effect. The place that can show value is in the art of command and various experiences.

Simply put, the history of relying on pure martial arts to gain merit will soon pass, and those who have not kept up with the pace of the new era are destined to be eliminated.

"Your Majesty." Zhang Shicai asked Liu Yan, regardless of the military general's mood, "Would you like to visit the next place?"

Liu Yan was able to guess that the Shaofu Ordnance Industry Research and Development Department must have some new achievements that made Zhang Shi ask such a thing.

Everyone left this rifle shooting range and did not go far to another shooting range.

The shooting range is the same, but the location is changed because the shooting range is also different. For example, rifles and artillery are also used for shooting, and the shooting distance and the degree of attack are different.

Liu Yan originally thought he would go to the artillery test firing site, but he didn't expect that the place he came over was also a firearms firing range. Before he had time to be confused, his eyes saw a big guy at the test firing position.

It was a multi-barreled instrument with a base to support the barrel. The overall look was both weird and hideous.

"You guys did it!" Liu Yan would be surprised. That guy is infinitely close to the Gatling machine gun at all, but it looks much bigger. He approached and stroked the suspended bullet chain, and asked Zhang Shi: "The bullets are already in mass production?!"

Flintlock guns also need to carry out the steps of charging and projectiles, and then the evolution is to post-load the gun.

The emergence of the cartridge bullet is a revolution in the evolution of firearms. The rifle no longer needs to be operated separately from gunpowder and projectiles. It should not appear until the eighteenth century, and has been repeatedly developed and matured, and finally became a modern bullet style.

The bullets that were loaded into the bullet chain reached about two centimeters in length. Liu Yan walked to the table next to him, picked up a bullet that was neatly placed, and observed the whole and found that it was completely indistinguishable from his own requirements. Some cartridge cases, primers, propellants and warheads are fully equipped.

"Your Majesty." Zhang Shi looked embarrassed: "The maximum output can be 1,300 rounds per day."

If one person or one machine can produce 1,300 rounds a day, it will indeed be a very good result. The key issue is that the entire Shaofu related agencies can be combined to have that efficiency.

"I am still improving..." Zhang Shi seemed to look at Ma Zihuan when he asked for help.

Liu Yan nodded to Zhang Shi blankly and looked at Ma Zihuan.

"Your Majesty, the ministers have already figured out the manufacturing process." Ma Zihuan seemed confident: "The new machine tool has been successfully developed. As long as special parts can be developed, the output will be increased."

What to do ~lightnovelpub.net~ It must have specialized components. The Han Empire is not short of metal at all. What it needs is to accumulate on the road of science. As long as there is enough perseverance, there are diversified talents and talents. With sufficient funds, the pace will never stop, on the contrary, it will go faster and faster due to the continuous accumulation of basic science.

Considered by Liu Yan as a big gunner, it started shooting under the operation of professional personnel.

There is no such thing as pulling the trigger. It is the operator who constantly shakes a handle, and each shake is a primer shot of the bullet, and then the explosive lasing process of the bullet is presented.

Under the constant "boom boom boom" movement, the distant target was torn to pieces, but the big guy was dumb in less than twenty seconds.

"This is..." The professional engineer checked it and reported profusely: "It's stuck."

Just now, most of them were stunned, knowing that the hideous weapon still has major flaws. On the one hand, it was relieved, and more was a pity.
