At this time, the Ming army's bowl mouth gun and other fire guns belong to the original arquebus, there is a metal hook on the gun, one end of the hook is fixed on the gun, and can rotate around the axis; The other end holds a burning fire rope, and when firing, push the metal hook into the fire door with your hand, so that the fire rope ignites the black ~ gunpowder, and then launches the projectile contained in the chamber.

Compared to full-fledged flintlock pistols, arquebuses have many drawbacks, the most obvious being that the firing process is very complex and slow.

Qi Jiguang once recorded more than a dozen procedures for using arquebuses in "Qi Jiguang's Art of War", and in Europe at the same time, there were also relevant documents describing the firing steps of arquebuses, which were divided into 25 steps, which were more cumbersome than the arquebuses of the Ming Dynasty.

The second is that the arquebus cannot be used in rain, snow and windy weather, the rain will wet the ignition of the medicine door, and the wind will blow away the ignition powder of the medicine door. Once this happens, it will be fatal on your life-and-death battlefield!

Liu Juntao was accustomed to all kinds of advanced firearms in later generations, and he hated the cumbersome steps of arquebuses.

In Liu Juntao's words: "The speed of firing two shots a minute is intolerable!" ”

Therefore, Liu Juntao specially designed the mechanism of the flintlock pistol on the drawings of the bird gun that he had improved, which solved the above shortcomings of the arquebus.

The flintlock pistol is actually not complicated, it is a flint clamped on the jaws of the hammer, and there is a blow anvil on the side of the fire hole. When the gunner fires, as long as the trigger is pulled, the flint is struck on the edge of the fire door under the action of the spring, and a spark can be generated, which can ignite the gunpowder and fire.

In this way, the steps of shooting are greatly simplified, the firing rate and shooting accuracy are improved, so that the shooting speed of the firecracker catches up with or even surpasses that of the archers, and truly forms a suppression of firepower!

Moreover, in order to make the new bird gun he designed can be used in windy weather, Liu Juntao also deliberately installed a lid on the top of the medicine pool, and when the fire gun hand pulled the trigger, the lid on the medicine pool automatically opened, and at the same time, flint was used instead of the fire rope.

At this time, Liu Juntao explained the structure of the flint hair in detail to Zhang Baigui and others, in order to help everyone quickly understand, Liu Juntao also deliberately found charcoal and paper, and drew while talking, decomposing and drawing every detail.

Although Zhang Baigui and other craftsmen are not craftsmen who specialize in building firearms, they have basically dealt with steel for many years, and they still have an understanding of the principles of some machinery.

After Liu Juntao's explanation, Zhang Baigui and others suddenly felt enlightened, and everyone felt that a door full of novelties was open to them!

At this time, it was close to noon, but Zhang Baigui and other craftsmen were not tired at all, and still pulled Liu Juntao to ask questions in the east.

Liu Juntao took another time to satisfy everyone's thirst for knowledge.

"Master Zhang, I have explained the firing structure, so let's continue?"

"Go on! Go on! ”

Looking at Zhang Baigui, whose eyes were shining, Liu Juntao was also amused in his heart.

Liu Juntao still remembers that when he first explained to him that he wanted to build firearms, Zhang Baigui was so frightened that he even spoke out against building firearms several times. Who would have thought that at this time, Zhang Baigui was like a diligent and studious "three good students", full of interest in building firearms, and pulled Liu Juntao to ask non-stop.

So, Liu Juntao continued to talk to Zhang Baigui and other craftsmen.

After there is no problem with the barrel and firing device, it means that the main part of the new bird gun has been completed, and the next step is to further improve the performance of the new bird gun.

For example, steel is used to make the body parts to enhance the strength and durability of the new bird guns, and hardwood is used to make wooden butts and body guards.

At the same time, in order to shoot effectively, Liu Juntao also deliberately designed the butt of the new bird gun as a rooster neck butt type, so that it is easier to hold and aim close to the cheek, and designed a more prominent simple front sight at the end of the gun to help the fire gun hand aim. In addition, Liu Juntao also prepared to install two movable gun strap buckles made of stainless steel to facilitate the long-distance march of the young and strong guards.

After talking about this, Liu Juntao only felt that his mouth was dry, he drank a large bowl of boiled water, wiped his mouth with his sleeve, and said: "The rest of the thing is to assemble, I think our War Bureau has been studying the bowl mouth gun for so long, there should be no problem with the assembly, right?" ”

Zhang Baigui looked at the thick pile of drawings that had accumulated on the table, nodded and said, "No problem!" ”

At this time, Liu Juntao took out another drawing and said with a smile: "Since there is no problem with the assembly, then I will add another magic weapon!" ”

"And the magic weapon?"

At this time, Zhang Baigui and other craftsmen were completely shocked, and they couldn't imagine what else Liu Juntao had done amazingly.

In fact, the last drawing that Liu Juntao took out was the design style of the casing bayonet and its card holder! A sliding tenon bayonet and bayonet mount are installed on the mouth of the gun so that the bayonet does not fall off and does not affect the shooting.

Now the Bureau of Warfare is able to smelt a sufficient amount of steel to make bayonets!

You must know that the invention of the bayonet was an epoch-making invention in the era of flintlock pistols, and its significance was no less than that of flintlock ignition instead of arquebus ignition.

Thanks to the advent of the bayonet, musketeers no longer needed the protection of spearmen, and while maintaining long-range strike capabilities, they also had a certain melee ability. Armed with bayonets, musketeers were no longer as vulnerable to cavalry as they used to be, and pure musketeers replaced muskets and spears!

After listening to Liu Juntao's explanation, Zhang Baigui couldn't sit still, and directly lit a fire and prepared to make a bayonet himself.

Under the guidance of Liu Juntao, Zhang Baigui was busy for almost an hour, and an unpolished bayonet was born!

Liu Juntao took a somewhat black bayonet, and said excitedly to Zhang Baigui: "With the bayonet and the new bird gun, from now on, my Yushan Collective Guard can cancel the sword and shield hands and spearmen!" In the future, the War Bureau suspended the creation of shields and spears, and did its best to create new bird guns and bayonets! In addition, in order to facilitate the use of fire guns for assassination, the body of the new bird guns must be lengthened, and the bayonet must be six feet long (1.8 to 1.9 meters long)"

Zhang Baigui couldn't help but be stunned when he heard this, and asked, "Isn't the escort team going to practice again?" ”

"Of course!"

Liu Juntao said with a smile: "It's just that the retraining of the escort team is not a matter of the near future. As for when the escort team will re-practice, it depends on the output of our military warfare! ”

When Zhang Baigui heard this, he suddenly felt that he had a heavy responsibility, and the speed of the progress of the military battle and the level of output were directly related to the strength of the Yushan Guards!

At this time, Zhang Baigui remembered something and asked, "By the way, Juntao, if the escort team cancels the pikemen, what will happen to our opponent Arima team in the future?" Will this new bird gun be able to withstand the onslaught of the horse team? ”

Speaking of this, Liu Juntao also hesitated, thought for a while, and said, "It should be possible!" But for the sake of safety, we have to create some small things in the War Bureau! ”

After speaking, Liu Juntao drew the silk mesh of the war subway in later generations, as well as the chariots and horses commonly equipped by the Ming officials and troops at this time, and asked Zhang Baigui to build them together.

Zhang Baigui couldn't keep up with Liu Juntao's train of thought at this time, especially after seeing the pattern of the subway wire mesh, and after listening to Liu Juntao's explanation of how to use it, he gasped and exclaimed: "How much pig iron does this cost?" It's too much money! ”

Liu Juntao said with a smile: "Pig iron? How can the barbed wire made of pig iron break as soon as it breaks? I'm going to use stainless steel! ”

"What!"

At this moment, all the craftsmen around felt extremely painful, and they all exclaimed.

Liu Juntao said with a straight face: "Compared with my brothers in the Yushan Guards, what a little silver!" What can be solved with silver, you must not let the brothers of the escort team fight hard! ”
