God Machine Gun Factory, Shooting Range.

After the soldiers tested the "Wushi rifle", Zhu Cihong, who was excited, personally operated the gun and shot to feel the power of the world's first breech gun.

The shape of the Wushi rifle is similar to that of the Hanyang in later generations, and the loading is also very simple.

When the trigger is pulled, the firing needle pierces the cap piece, causing the primer to ignite by friction and impact, igniting the propellant (black powder) in the paper case, and then pushing the warhead in front.

After Zhu Cihong finished firing a shot, he rotated the wrench on the gun, then turned on the bolt, loaded the next bullet, and then pushed the bolt into place and rotated to close the chamber.

The whole operation is not much different from the Mauser rifles and Hanyang-made in later generations, the only obvious difference is the bullet.

The bullets made in Hanyang are brass cartridge casings, while the cartridge casings of the Wuju-10 rifle are paper casings made of oiled paper and flax.

Whether it is a brass bullet or a paper shell bullet, the core part is a primer.

In the past, the muskets of the Ming army, whether they were bird guns, Lumi guns or flintlock guns, needed to be loaded with gunpowder and bullets (lead bullets), and the bullets were loaded with gunpowder, even the most advanced Heding rifle (Mini rifle) at that time was also operated in this way.

In order to make a breech gun, it is necessary to integrate gunpowder and lead bullet in a single cartridge case, eliminating the need to reload gunpowder, so as to increase the rate of fire exponentially.

The biggest technical difficulty of breech guns is the primer in the bullet, and researchers need to consider how to use flintlock impact to ignite the primer of the bullet, ignite the propellant through chemical reaction, and push the bullet out of the chamber.

This tests the performance of the primer, which requires a material with a high sensitivity to flames, needlepunctures and impacts, and ordinary black powder is certainly not enough.

Because the quality of the spring is not complimentary, the probability of not hitting is very high, maybe a dozen shots, barely able to hit once.

In the past ten years, the Royal Academy of Sciences and the Military Research Institute have mainly devoted themselves to the study of primer materials, and have gone deeper and deeper in the field of chemistry.

In the seventh year of Tianwu, an academician of the Royal Academy of Sciences finally succeeded in developing a kind of mercury thunderate with relatively high sensitivity and gunpowder power, which created conditions for the development of primer.

Thundermercury is one of the most sensitive gunpowders, and it explodes with a single impact, and it certainly cannot be used as a propellant for bullets.

In the 17th century, the soldier had to load the black powder before firing it, and he had to pound it with a pole.

If it's thunder mercury, let alone pounding it, even if you put this thing in a medicine bag and hang it on your waist, and encounter a slight bump and bump during the march, this thing will explode directly, and the kidneys will be injured for life, and the heavy will be life-threatening.

Lei Mercury is particularly afraid of moisture, and if he sucks a little water, he loses his temper, and he can't light it, just like a tsundere woman with a big temper.

However, a woman has a role, and the sensitive and tsundere trait of thundermercury reminds a person of the use of thundermercury to induce explosive ejaculation.

This person is Sun Heding's second brother Sun Hedou, a guy who likes to play with cannons, known as "Sun Ercang".

There are two strange characters in the noble class of the Ming Dynasty, one likes to play with guns, and the other likes to play with cannons, the second son of Li Tingbiao plays with guns, Li Yuanfang, and Sun Hedou plays with cannons.

Needless to say, Li Yuanfang, as a high-level of Jinyiwei, no matter where he goes, he must carry a few pistols on his body, and he also likes to let prisoners guess bullets.

Sun Hedou is because of his background, he likes to play with firearms since he was a child, and after joining the Tianwu Army, he is even more fond of grenades, artillery and other lethal things.

When Chongzhen was fourteen years old, he was ordered to go to Lu's house to protect Lu Xiangsheng, and in the face of the green skin hired by the profiteer, he directly threw a grenade to blow it up, killing a piece, and he didn't bother to use a knife or a gun.

In recent years, the two of them have also become famous, known as the "South Gun and North Artillery", Li Yuanfang, the gun bully of the South China Sea, and Sun Hedou, the gun bully of the North Plains.

If there are conditions, Sun Hedou also wants to carry a cannon with him.

As the saying goes, there is nothing difficult in the world, only people who are afraid of it, and now Sun Hedou, with his own efforts, finally realized this wish, carrying a cannon with him.......

In the eighth year of Tianwu, Sun Hedou went to the Royal Academy of Sciences to find his brother Sun Heding to see if any big man had invented something new, such as a cannon that could be carried on his shoulder......

Disappointed, he stumbled upon the invention of mercury thunderate.

Sun Hedou was inspired at that time and thought of his dream - mortars.

He thinks that the artillery run thing is easy to carry and very useful on the battlefield, but the reload speed is too slow.

If the Regon primer is loaded on the flowering shell, the shell can be loaded through the muzzle, and it can slide down by its own gravity to hit the bottom firing pin of the barrel at a certain speed, so that the primer on the shell will fire and ignite the propellant in the shell.

Once this research is achieved, then the Ming artillery will be invincible!

Because this thing eliminates the cumbersome reloading steps, the artilleryman only needs to take the shell and stuff it inside, then bow his head and cover his ears, and then reload, conservatively speaking, the rate of fire can be increased by at least ten times!

In the past, it was possible to fire two shells a minute, but now it is no problem to fire twenty or thirty shells a minute.

And even more so, if you make a small mortar (grenadier), you can take it with you yourself!

Moreover, this kind of small mortar can allow the infantry to be equipped on a large scale, and a squad of ten people is equipped with one or two, and wherever they go to bomb it, who can be the opponent of the Ming army in the whole world? Even if God comes, he can be blasted to slag!

So, Sun Hedou informed his brother Sun Heding of this idea and asked him if he had done anything.

Sun Heding didn't say a word, he arranged for the implementation of this plan on the same day and listed it as top secret!

Mercury thunderate can be used as the primer of the shell, and naturally it can also be used as the primer of the bullet, and it is on this basis that Chuan Jianguo invented the breech gun.

That is to say, if there was no mercury thunderate primer, the invention of the breech gun would have been delayed for many years, and no matter how good Chuan Jianguo was, he would have no way.

Of course, even without mercury thunderate, the breech gun would have been invented, and it was only a matter of time, because humans would always find a way to kill each other.

Zhu Cihong fired fifteen bullets in a row, and finally stopped under the strong persuasion of Zhao Jinglin, the Marquis of Shenji.

Because Zhao Jinglin was afraid that he would have an accident, every time Zhu Cihong shot a bullet, it was like hitting him.

In fact, his worries are unnecessary, what can be inspected by the emperor has already been tested countless times, and the probability of an accident is about the same as the probability of winning the first prize in a lottery ticket.

"This gun is very good, hurry up and build it as soon as possible!"

Zhu Cihong threw the rifle to Zhao Jinglin and said, "Is it difficult for your ordnance department to build a batch within two months and equip the Tianwu Army with a brigade, at least two integrated regiments?" ”

Zhao Jinglin replied immediately: "There is no problem, the minister promises to complete the task!" ”

If it had been placed in the past, even if there were many craftsmen in the Jiangnan Ordnance Bureau, it would not have been able to produce four or five thousand muskets in just two months.

The earlier rifles were hand-built by professional gunsmiths, the speed was very slow, and each rifle was different, even if there was a problem in a small part of the rifle, the whole gun had to be sent to the rear for repair.

The current Jiangnan Ordnance General Bureau, the use of mechanized production machines, steam engine in the Ming Dynasty after the successful research and development, the first time was used in the military industry, followed by civilian.

The Wushi rifle is not a delicate object, and the components are also very simple, and the machine driven by the steam engine can process and produce parts in large quantities, making the Wushi rifle the world's first weapon with interchangeable parts.

Its bolt, barrel and bolt assembly and other parts can be easily installed on any Wushi rifle, which is also the confidence of Zhao Jinglin, the secretary of the Ordnance Department.

Zhu Cihong sighed a lot, these high-tech products, driven by himself, have advanced by more than 100 years, and the times have really changed!

In the new era and new products, someone must always experience and feel it, and this kind of cherished place, Emperor Zhu naturally thought of Little Japan and asked them to try it first.
