"Keng~~Boom~~Boom~~~"

"Yoshi! Takechiyo, this new iron cannon you supervised has made a lot better than the previous Kunitomo cannon in terms of range and accuracy! What's even better is that this iron cannon can be fired without a match rope.

, in this way, the problem of excessive use of iron cannons that is limited by the weather will be solved for the most part!"

"Hai, thank you father for the compliment. Speaking of which, father is indeed the best iron cannon master in Tokaido. He still hit the target with one shot from such a long distance."

"Hahaha, don't underestimate your father. Although I am sixty-two years old, I can still eat three bowls of miso rice every meal, and I won't stop eating in the middle of the meal."

"Hahahaha~~How can my father's talents be compared to Lian Po's?"

1605, Edo Castle, Japan.

At this time, Tokugawa Takechiyo, who was about to turn five years old, was accompanying the de facto ruler of Japan, Tokugawa Ieyasu, at a secret shooting range in the suburbs, experimenting with the new iron cannon that he had recently guided the craftsmen to make - a flintlock musket.

The development of thermal weapons certainly began with light weapons. The most representative of these is the musket or rifle used by infantry.

The earliest controlled firearms began in the Southern Song Dynasty in China, and then spread to the West with the iron hoof of the Mongols. Then around the mid-to-late fifteenth century, the real matchlock gun appeared in Western Europe. It was introduced to Japan in the sixteenth century, and Japan

It was called an iron cannon. In the later Ming Dynasty's battle against Japanese pirates, the matchlock gun used by the Japanese was introduced to China, and the Ming Dynasty imitated it and called it a bird gun.

The earliest matchlock gun, or iron cannon, or bird gun. Although the power is not small, heavy armor is basically unable to resist within 100 meters, but its limitations are also great. The most direct is that the firing method requires an open flame, which leads to

Matchlocks are subject to many weather restrictions.

Military needs promoted technological progress, and the backwardness of the firing device prompted skilled craftsmen from various countries to work hard to improve it. First, they invented the revolving musket, and then in 1547, the Frenchman Mahan invented the flintlock musket.

(In the historical perspective, due to the huge interests of the original matchlock manufacturers, there was a flintlock gun, but the inventor was assassinated instead. The French military refused to use the flintlock device on the pretext that the flintlock device could not effectively ignite gunpowder.

Strange thing. It wasn’t until the middle of the 17th century that flintlock muskets were generally installed in the armies of European countries.)

After the firing device was improved, Europeans began to pursue greater range and accuracy of muskets: matchlocks and early flintlocks were both smoothbore guns, and there was no rifling in the barrel - the range was short and the accuracy was low. So there was the invention of muskets.

A rifled gun (rifle) with grooves in the barrel to increase range and accuracy.

However, the emergence of rifled guns has brought new problems: rifles in this era are all muzzle-loading guns, and bullets are loaded from the front of the barrel. In order to ensure the range of the bullet, the diameter of the bullet will generally be slightly larger than the barrel.

One point - only in this way can the airtightness of the gunpowder be ensured after it is ignited.

In the past, the barrel of smoothbore guns was basically smooth. Although the bullet was slightly larger than the barrel, with a little force, the bullet could still be fed into the barrel relatively easily. But after the uneven rifling in the barrel,

The problem was huge: it took half a day to put the bullet in, and it took more time to fire a shot than a musket. So European countries have been struggling for many years between accuracy and speed.

This problem persisted in history until 1823. The British drew on the principle of blowing arrows from local Indians and proposed changing the shape of the bullet from a round to a cone, and adding tail expansion material to seal the barrel gas.

Suggestion. And then there was the reason for the interest relationship. This suggestion was strangely rejected by the British military, and in the end it was carried forward in France.

In 1849, the French Minie produced the famous Minie bullet according to the British creativity: the bullet was conical, with a diameter smaller than the barrel (it was easy to insert into a rifled gun), and there was a conical cavity at the bottom of the bullet.

Block it with a wooden plug. After firing and igniting, the wooden plug expands so that the gas in the barrel will not leak. This solves the shortcomings of the rifled gun.

At this point, problems such as speed, accuracy, range, firing device, etc. of muzzle-loading muskets have been basically solved. The development of muzzle-loading guns has now reached a mature stage. However, the peak muzzle-loading guns failed to make much of a name on the battlefield.

.Because, thanks to the improvement of metallurgical level, by this time, the breech-loading gun had already come out. This is the famous m1841.

Zhu Youdong probably knows some of the above knowledge: for example, he still knows about flintlock guns and Mini bullets. But what is the significance of Mini bullets? Sorry, he doesn't know - he is a doctor and a history buff

, not a military enthusiast.

And this time traveler from Japan, whose current name is Tokugawa Takechiyo, knows all these things.

Because, before time travel, his job was as a cartoonist.

Don't look down on cartoonists, the competition in the Japanese cartoon industry is as fierce as it was at the starting point.

As a cartoonist, in addition to basic painting techniques and imagination, more importantly, you need a lot of basic knowledge. Most people born in the 1980s in China have read Saint Seiya, and they should be able to see this in the book.

The author of this book has a good knowledge reserve of the Greek mythology system. Most people born in the 1990s have watched Naruto. Who dares to say that the author only has imagination and does not have a rich knowledge reserve? Everyone born in the 2000s has probably watched Attack on Titan.

Although the equipment of the human corps is science fiction, it also has a high degree of physical basis...

As for this time-travel cartoonist, what he is good at is originally military cartoons. The cartoons he draws are based on the background of the Warring States Period and the World War II era that reflect Japan's communist ideology (there are many such cartoons in Japan, but

Not easy to see in China). Such people may not be as good as real military experts or engineering men, but they still have a clear understanding of the basic context of the development of military science and technology.

Four years after traveling through time, he was officially enlightened. The teachers sent by Tokugawa Ieyasu to guide him were Tadakatsu Honda, the person in charge of force, Masanobu Honda, the person in charge of intelligence, and Nagano Okubo, the financial manager.

As a result, although due to physical reasons, Takechiyo could not be more impressive in terms of military force, in terms of strategy and financial sensitivity, Honda Masanobu and Okubo Nagaan were quickly and completely convinced.

From 1604, Takechiyo began to practice his old profession: drawing comics. The theme of the comics is the two hundred years of the Warring States Period.

In this manga, the samurai of the Tokugawa family are of course all handsome in appearance, extremely noble in character, and outstanding in martial arts. And the enemy of the Tokugawa family, Toyotomi Hideyoshi, is of course painted with a monkey face.

Once this propaganda expression, which only began to appear in the 20th century, appeared in this era, the effect it caused was extremely sensational. The samurai, ministers and wealthy businessmen throughout Japan all began to treat the Tokugawa family with a more humble attitude.

Wagging one's tail and begging for mercy: The Japanese in this era pay more attention to being famous in history, and how to leave a good reputation and a good image in history in the future, this comic will play a great role.

In addition, Takechiyo spent a lot of effort and energy to guide Japanese iron cannon production craftsmen to vigorously develop a new generation of muskets.

To be fair, in terms of history, the pinnacle of the matchlock gun was not in Europe but in Japan: when the matchlock gun was introduced to Japan, it was Japan's Warring States Period. The overall war situation promoted the development of the matchlock gun. From the barrel

In terms of quality, gunpowder ratio, match rope material and many other aspects, Japanese iron cannons indeed surpassed the Ming Dynasty's cannons.

Therefore, Japan has the technical foundation to develop a new generation of muskets.

As a time traveler, Takechiyo certainly wanted to develop a breech-loaded gun directly in one step, but after countless experiments, he still had to accept the failure: the firing device of the breech-loaded gun is a firing pin, which is aimed at a country.

The level of forging is extremely high. At the same time, there are no high-strength springs or screws. How can you make a breech-loaded gun? Just make a breech-loaded gun. If you want to mass-produce customized copper-cased bullets, then

It's something that can torture people to death.

So Takechiyo had to settle for the next best thing and make a flintlock gun. And it was a flintlock gun that was completed in one step: the firing device used flint to ignite, the barrel had rifling, and the bullets were Mini bullets. This was already the pinnacle of the muzzleloader.

Level.
