The advent of fixed-loading ammunition has greatly increased the frequency of firearms, and since then, cold weapons have really come to an end. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Several veterans under Guo Sheng used this kind of fixed ammunition when testing the gun, and even within two minutes, they scored the highest score of seven rounds, I believe that after everyone is familiar with this charge, three rounds are fired in one minute, and there is no problem at all, which is a level higher than the previous flintlock pistol, compared with the maximum speed of two rounds a minute.

Time is of the essence on the battlefield, and every additional bullet fired will increase the odds of victory.

"It's nothing, if you can make a breech gun, that's what you call it powerful, you think about it, when a soldier fights, he can finish loading by lying on the ground, we can hit the enemy, and the enemy's bow and arrow can't hurt us at all, this is the foundation of the victory of firearms." Li Hongfei talked eloquently.

Breech guns, also known as breech-loading rifles, are the predecessors of modern rifles.

At this time, the Ming Dynasty did not have a breech-loading rifle, and the Franc machine gun was a rear-loading repeating rifle.

However, the Franc machine gun is a large-caliber flintlock pistol, which is between the guns and guns, and is based on the arquebus obtained from the captured Franc machine (Portuguese) ship.

The Franc machine gun has 9 guns, which can fire continuously and quickly, and weighs more than ordinary flintlock guns, but is more powerful and has a longer range, similar to the heavy machine guns of later generations.

"That's what the adults said, but it's really difficult to make a breech gun, and many parts may have to be redesigned." Bi Maokang was embarrassed.

Gun breech loading is relatively easy to design, gun breech loading is difficult because many things are miniaturized and cannot be used.

Although the Franc machine gun was successfully transformed, it was also the lightest rear loading firearm in the Ming Dynasty, and it was almost impossible to change the smaller bird gun into a rear load.

Bi Maokang has studied firearms for 40 years, and he thinks that there is nothing he doesn't know about firearms in the world, but chatting with Li Hongfei during this time, he feels like a frog at the bottom of a well.

Li Hongfei casually improved a fixed ammunition, which can increase the rate of fire of the flintlock pistol by seventy percent.

"Don't blindly miniaturize firearm parts, you can start from the ignition device, the previous arquebus to the current flintlock pistol, isn't it because of the improvement of the ignition device, and a major breakthrough has been made?" Li Hongfei provided a new way of thinking.

"What do you mean, this flint ignites, can it go further?" Bi Maokang woke up like a dream.

If there is a better way to ignite and fire, then it is not difficult to build a breech gun.

"Nowadays, this fixed-loading ammunition is actually only a half-finished product, if it can combine the primer, propellant and projectile, then it can be regarded as a real fixed-loading ammunition." Li Hongfei said.

The final form of the rifle bullet in later generations was to combine these three.

"But the primer must come into contact with the flint to ignite instantly, and if the three are one, how can it be fired?" Bi Maokang became a curious baby.

"Hit with a firing pin."

Li Hongfei explained the firing principle of the firing pin in later generations to Bi Maokang.

However, Li Hongfei was only half-baked, and after he finished explaining, Bi Maokang was even more puzzled: "It's unlikely, flint firing is using the principle of flint ignition, how can this firing pin ignite the gunpowder in the barrel?" ”

The firing pin belongs to metal, if you want to hit the spark, you must collide with metal, or flint, and although Li Hongfei also means to collide with metal, but once the gunpowder is wrapped in metal and isolated from the air, how can it ignite?

This creates an endless loop, in which the primer, propellant, and projectile are three in one, and the gunpowder cannot be ignited at all, and once it is separated, relying on the flint to ignite, it can only be made into a heavy weapon like the Franc machine gun at most, and it cannot be miniaturized at all.

"The key to this is the activity of the primer, if a new type of gunpowder can be concocted, which can be ignited by impact, then all problems will be solved." Li Hongfei said.

"A primer that can be ignited by impact alone? Is there really such gunpowder? Bi Maokang said he was incredulous.

"Of course, in the early years, the official heard that a Westerner mentioned this kind of primer, its medicinal properties are extremely active, and the slightest impact and friction can ignite instantly, but the name of the Westerner is too awkward, and the official can't remember the name clearly." Li Hongfei really couldn't make it up, so he had to use Westerners as a cover.

The set of principles he said earlier was the principle that had been finalized in later generations, and the key was in the aspect of the primer, the gunpowder used in the primer was not the black powder commonly used today, but Li Hongfei's chemical results were not very good, so he didn't figure out what the primer was.

"It's mercury, what Master Li said, it should be the mercury smelt that has been blending before the old decay." At this moment, a voice suddenly interrupted the conversation between the two.

Mercury is known as mercury in the West, and mercury can produce another compound, thundermercury.

Thundermercury is a white or gray crystal, is the earliest used initiating agent, when dry, it is extremely sensitive to vibration, impact and friction, and is easy to be detonated by sparks and flames, or pressure mold casting under high pressure, and copper reaction to form alkaline thundermercury copper, so that it has greater sensitivity.

"Who are you?" Li Hongfei was pretending to be forced, and was suddenly interrupted, not to mention how depressed he was.

The man who came was an old man of about sixty years old, with a long goatee, a pair of dark brown eyes shining in his slightly sunken eye sockets, and his hair was combed very carefully, without a trace of messiness, but the silver white hair was still clearly visible in the black hair.

"Song Yingxing, the former governor of Bozhou, has seen two adults." The visitor saluted and reported his name.

"Song Yingxing? You are Song Yingxing, who wrote "Heavenly Creation", Lord Song! Li Hongfei was surprised.

I had learned that Song Yingxing was coming to Suzhou before, but I had been busy with the affairs of Baoshan Town recently, and I forgot about it, and now that the other party came directly to him, can Li Hongfei not be surprised!

"The old man arrived in Suzhou the day before yesterday, and learned that Lord Li was on business in Baoshan, and the Ordnance Bureau had also moved here, so I asked a few adults from the East Factory to bring the old man over and meet with the adults. Song Yingxing said.

In fact, Song Yingxing was originally very disgusted with coming to Suzhou, but the other party was a person in the court, and after Song Yingxing resigned, he was a common man, so he naturally didn't dare to fight with the official, not to mention that he was still a fan of Dongchang.

Later, on the way to Suzhou, I heard a lot of rumors, and after arriving in Suzhou, I learned about Li Hongfei's series of reform measures.

Song Yingxing was an official before, and he was also a person who strongly advocated reform, so he had a good impression of Li Hongfei and wanted to meet the newly appointed king of Suzhou as soon as possible.

Under the escort of Dongchang Fanzi, Song Yingxing came all the way unimpeded, the tent where Li Hongfei and Bi Maokang were discussing, and heard the conversation between the two.

When Li Hongfei talked about the new type of gunpowder, Song Yingxing finally couldn't help it and took over the topic...........
