He was going to draw nothing else but drawings of muskets and artillery, muskets were flintlock pistols and artillery guns were smoothbore guns.

In the era when the Manchu Tartars were still using revolver muskets, flintlock pistols were already very advanced in front-loading guns, and they were originally improved on the basis of revolver muskets.

The clockwork wheel from the revolver musket was removed, a flint was clamped to the jaws of the hammer, and an anvil was placed on the side of the fire hole, and the trigger was pulled when firing, and the flint was hit the side of the fire door, causing sparks to emerge and ignite the gunpowder.

The flintlock pistol greatly simplifies the firing process, improves the rate of fire and accuracy of shooting, is easy to use, and has a low cost and facilitates mass production.

However, although the flintlock pistol has a greater advantage than the revolver musket, it is also very limited, there is no way, the industrial level of this era can only be done to this extent, and the rear-loading gun is not to think about it.

So what Yang Yifei wants to make, something that is really ahead of this era, enough to crush the Tartar musket, is ammunition.

The biggest problem with the front-loading musket is that the charge is troublesome and the firing frequency is slow, and to change this situation, you can only work ammunition, so Yang Yifei plans to make "paper shell bullets".

This is an advanced gadget that was two hundred years ahead of its time, and with paper shells, it allowed muskets to have a rate of fire no less than that of double-barreled shotguns in later generations.

Because it is loaded very quickly, it is many times more convenient and faster than in this day and age to pour gunpowder into the barrel first, then tamp it with a whole strip, and then put in the projectile.

In the early eighteenth century, combustible shells appeared, and the materials of the shells were made of flammable materials such as nitrocellulose paper, linen, and leather.

Directly fill the flammable cartridge case with an appropriate amount of gunpowder and projectiles, and make it into a whole to form individual ammunition, which is the prototype of later bullets, and the cartridge case and gunpowder will burn together when fired.

Immediately after firing a shot, another paper shell is inserted into the barrel, and the hammer is broken to fire again, which takes only a few seconds.

The most important thing is that the use of paper shells makes the amount of gunpowder for each charge the same, and the range and accuracy of the musket are kept in a stable state, so that the accuracy of three points and one line can be achieved.

Unlike the musket of today's era, the weight of each charge is different, and its range and accuracy cannot be grasped at all, even if the front and rear two guns are aimed at the same place, the impact point of the shot is also very different, and the beating of people depends on lining up to set fire and shooting, which is the so-called shooting platoon gun.

With paper shells, the mode of combat can be changed, and there is no need to form an array, face to face with the enemy, and finally defeat both sides.

The musket team with paper shells can play positional warfare, trench warfare, and even guerrilla warfare with the other side, because such muskets can be aimed at the target and fire.

If the production of muskets and card-shell shells can keep up, maybe you don't have to engage the Tartars in hand-to-hand combat, bombarding them at long distances, muskets at medium distances, and thunderbolts at close range.

In this round, when the enemy gets close, it is estimated that there will be no one left, and even if there are people who rush over, they must be frightened and have no fighting spirit.

Yang Yifei will also add a design that can be loaded with a bayonet on the musket, the length of the musket is about one meter five, plus a sixty centimeter long bayonet, that is, two meters and one length, which can be used as a spear.

Long-range, medium-range, short-range, and close-quarters, all of which are within their own attack range, how can the other party fight with heaven and earth in such a battle?

Speaking of long-range firepower, Yang Yifei is also preparing to build a smoothbore cannon that is two hundred years ahead of this era, dominates an era, and is known as a passing artifact in later historical novels - Napoleon cannon.

The structure of the Napoleonic cannon is very simple, a base, a barrel, two wheels that can be maneuvered on the left and right, the process is not complicated, but the power is very strong, and the firepower is known for its ferocity.

Its ammunition is divided into solid bullets and flowering bullets, the range of firing solid bullets is 900 to 1200 meters, and the range of flowering shells is usually about 1000 meters, and the killing range is similar to that of mortars, with a radius of 16 or 7 meters.

In this era when field artillery usually had a range of between 250 and 600 meters, it was already a sling of everything.

Of course, don't tell me that the range of the Qing Dynasty's red-coated cannon was ten miles, what tonnage was the red-coated cannon? The barrel alone is three meters long, and the weight is more than one ton, which is extremely troublesome to move, and it is simply a live target, and more often used as a battery gun.

And the barrel of the Napoleonic cannon is 1.5 to 1.6 meters long, weighs more than 380 kilograms, and any mule can drag it away, is that the same thing?

To put it bluntly, the range of the old artillery depends on how big it is, and the larger the size, the longer the range, the needless to say?

Moreover, in this era when there is no radio, long-distance communication is impossible, and there is no such thing as artillery command professionalism and multi-element calculation, what is the use of having such a long range? I can't see each other, how can I fight? Do you want to shoot with chance?

So from any point of view, the Napoleon cannon is the most suitable artillery for the Heaven and Earth Society, and it is also enough to run amok in this era.

As a special soldier, Yang Yifei is naturally the most authentic military fan, and he knows almost everything about all kinds of weapons in ancient and modern China and abroad, especially those weapons that have influenced an era.

Chen Jinnan and Cai Dezhong have been guarding the side, watching Yang Yifei use a quill pen to draw the musket and artillery he designed one by one.

Not only the whole, but also the close-up and size of each part, all of which are clearly marked, and the most surprising thing for the two of them is that the picture is particularly three-dimensional.

After Yang Yifei finished drawing, he carefully told the two of them about the performance and advantages of these two weapons, and the two middle-aged men were as happy as two children of one hundred and forty or fifty pounds, and they couldn't wait for the things on the drawings to become real immediately, so that they could see and understand.

"Chief helmsman, Brother Cai, these two weapons plus thunderbolts will be the main war weapons produced by Thunderbolt Hall, which have taken into account the four combat distances of long-range, medium-range, process, and close-quarters, and are used for large-scale corps operations."

"In addition to this, I will also make some firearms with special functions for small-scale operations or special operations, and I will tell you more about special operations when I start to form a regular army later."

Chen Jinnan and Cai Dezhong found that once Yang Yifei began to think about firearms and war, his whole person changed, and he became very fanatical, and a pair of eyes couldn't help flashing in their eyes, some crazy light, and that kind of fanaticism even made them faintly afraid.

I'm afraid of something, of course it's a joke, the heirs of Perak Hall! It's normal to have this performance, the key is that the things he created can allow them to defeat the Manchu Tartars and recover the Ming Dynasty.

As long as this point is clear, Yang Yifei is the most important person in the Heaven and Earth Society, even if the Heaven and Earth Society is missing him Chen Jinnan, Yang Yifei must not be missing.

Yang Yifei has been busy since the morning, he didn't eat breakfast, and he was busy until dinner, and finally put down the quill pen.

After eating dinner and resting for a while, I found an open place on the mountain to practice.
