After turning a few passages again, the crown finally saw the legendary shooting room.

The weapons here, in addition to the conventional weapons, also have all kinds of new weapons, which the crown has never seen before, and there are weapons that he has seen.

The crown was brought under a sign.

"This is the history of firearms, you need to read the following carefully, and then we will start training, give you an hour to read, if you don't understand, you can ask me." Dropping this sentence, Wang Yuyan sat alone on the stool beside her.

Only then did Wang Mian seriously look at these firearms knowledge.

Early firearms According to historical records, the world's earliest tubular shooting firearm is the bamboo tube assault rifle created in the first year of the Southern Song Dynasty (1259 AD) in China, which is a tube made of bamboo, which is filled with gunpowder, and then installed with a "Zichao", after the gunpowder is ignited, it emits an explosion and flames, and shoots the "Zichao" at the enemy, and its sound can be transmitted to 150 steps away.

In principle, this "assault gun" is already close to today's firearms. At the end of the 13th century, China invented a metal tubular shooting firearm that became a firearm, which used gunpowder to fire stone bullets, lead bullets or iron bullets, which could kill and injure the enemy at a long distance.

After the gunpowder invented by the Chinese spread to the West, the first firearm appeared in Europe in the 14th century, the musket gun.

After the gunpowder invented by the Chinese spread to the West, the first firearm appeared in Europe in the 14th century, the musket gun. The original form of firearms in Europe was the 14th-century musket, consisting of a brass or bronze cylinder less than 250 mm in length, fixed to a wooden stick or long thatch 1.2 to 1.5 meters long. Caliber 2.5 to 4.5 mm, from a small hole in the tail of the barrel that communicates with the bore - the fire door ignites the gunpowder and fires a bullet made of stone or metal. Due to the fact that the gun could not be aimed, the accuracy of the shot was naturally poor. Its maximum range is about 180 meters, and its effective range is only about 45 meters.

In the middle of the 16th century, ramming and flint guns appeared. The flint is hinged to the medicine pool by a right-angled medicine pool cover that serves as a lighter sheet metal on the clamp head, and the trigger is pulled, and the fire plate is hit at any time under the action of the spring, bursting out with sparks and igniting the gunpowder. This strong structure golden egg, easy to use, improved shooting accuracy.

By the end of the 17th century, flint guns used in Europe were widely equipped with bayonets.

The earliest wheeled flint guns appeared in Nuremberg, Germany, at the beginning of the 16th century, which had a steel wheel with a clockwork mounted on the side of the butt. Before shooting, the shooter first tightens the mainspring with a wrench, and when shooting, the steel wheel is freed, and when the wheel rotates rapidly around the axis, its knurled edge rubs against the flint mounted on the nose, which can emit strings of sparks and ignite the gunpowder. However, its structure is complicated, the cost is expensive, and it has not been widely promoted.

Early firearms, when used, were used from the muzzle of copper strips such as gunpowder and projectiles, called front-loading guns. At that time, the caliber of the barrel was large, the operation was complicated, and the heavy loading was not conducive to the concealment of the shooter, and it was not convenient to wipe, so in the 16th and 17th centuries, the structure of the afterload was tried, but it was abandoned because it could not guarantee the blocking of gunpowder gas and the inconvenience of operation. The muzzle of the early guns was about 20 mm, because it was difficult to make small-caliber guns in the Middle Ages, and it was used in the army for nearly 300 years because it simplified the firing operation and improved the accuracy of shooting. The development of firearms in the early days was mainly the evolution of the ignition method, with the aim of continuously improving the ease of use and working reliability of the ignition mechanism.

After the invention of the firing ignition method using thunder mercury as the firing gunpowder, the fixed gun cartridge appeared, and the rear loading gun that was loaded from the tail of the barrel was popularized, and led to the creation of modern rifles. Later, firearms underwent the development process of mechanization and automation, and a variety of modern firearms with different structures and combat uses appeared.

The Evolution of Modern Guns In 1807, the British priest A.J. Forsyth invented the ignition device using thunder mercury firing charge, and later someone invented the fire shape. The fire cap is placed on the anvil with a fire door, and the gunpowder in the chamber can be ignited by striking the fire cap, which is the fire engine. A gun with such a firing machine is called a firing gun.

At the beginning of the 19th century, fixed-loading ammunition was developed in France. The paper shell of this bullet is equipped with a metal substrate with firing charge, and after the gunpowder is loaded, it is integrated with the bullet. The fixed-loading cartridge greatly simplified the operation of loading ammunition from the barrel to non-loading, creating conditions for the widespread use of rear-loading guns with ammunition from the tail of the barrel.

In the 15th century, straight rifling lines were carved into the chamber of the front-loading gun to contain gunpowder residue and to make it easier to load the projectile from the muzzle. In the 16th century, people began to change the rifling in the barrel to a spiral shape, so that the long lead shot shot could rotate and keep the flight stable, improve the shooting accuracy, and increase the firing range, but because the gun with spiral rifling, the front loading was very time-consuming, so it was not until the invention of the fixed gun cartridge and the rear loading gun was popularized that the rifled gun was widely used.

In 1828, the French officer Delvin designed a weak barrel with a chamber at the tail of the barrel, using a long projectile, still loading gunpowder from the front of the barrel, but the rifling has become a rotating type. The firing range and firing accuracy of this gun increased significantly. Engels became the "father of the modern rifle" of the Delvin rifle.

In 1848 the Mingne was not strong, and its construction forced the Erwin rifle to be more simplified, eliminating the need for a special medicine chamber and changing the projectile to a hollow type. In the history of the development of guns, the ammunition has been changed from front-loading to rear-loading is a major progress.

In 1835, Dreisai of Prussia designed a breech-loading shotgun and in 1940 equipped the Prussian army. This earliest by the shooter to operate the handle, is the bolt forward and rear sliding to load and retreat to get disease and death after the loading of the bullet, the use of spiral rifling, rotation of the bolt, with a long rod-shaped firing needle to pierce the paper bullet casing, impact the firing charge in the bullet, fire the warhead, called the firing gun. It significantly increases the rate of fire and can reload and fire in any position. The needle gun has a caliber of about 15 mm, the combat rate of fire is 4 to 5 times higher than that of the firing gun, and it can fire 6 to 7 rounds per minute.

In the 60s of the 19th century, during the American Civil War, there was a man named Gatling who sought a way out of the high rate of fire in the mechanization of loading. On the basis of multiple barrels, he used a handle and a drum wheel to rotate the barrel, and when the drum wheel rotated, the mechanism completed the action of firing the gun, loading, locking, waiting and firing, and could fire 300 to 500 rounds per minute during intense operation. The Gatling mechanism played a role in the development of automatic weapons, and when it appeared, the mechanical construction necessary for automatic weapons had a pattern.

Seeing this, Wang Mian is already two big heads, but in order to be able to use guns well in the future, he must keep this knowledge in mind, at least to avoid unnecessary trouble in the use of guns.
