The Rise of the European Emperor

It's not been a day or two for Marin to do this kind of thing. For the previous steel nail slug, he carved patterns on the bullet and drew some strange patterns to mislead enemies who might get the bullet.

And this time, after thinking of the wonderful idea of ​​this "spell", Marin also changed the mold for making the slug, and engraved a "spell" on the warhead - "Avada Kedavra"...

The Avada Kedavra Curse is one of the three killing spells in "Harry Potter", but it sounds more mysterious and higher than the other two spells-"Crucicum Curse" and "Imperius Curse". The most important thing is that it sounds confusing and I don't know what it means.

Like "Cruciatus Curse" and "Imperius Curse", the meaning is too obvious, people know what it is when they hear it. But these two spells have nothing to do with the firing of bullets, so it's not easy to be far-fetched.

And "Avada Kedavra" makes people confused after hearing it, but after thinking about it, it is still confusing, which can enhance the sense of mystery. Coupled with some ghost-like patterns, it makes people even more confused. In this way, Marin's goal of misleading the enemy can be achieved.

But what's shameless is that, in order to keep secret, Marin even fooled the most loyal teenagers together...

Marin stipulated that in the future, the young musketeers under his command must shout "Avada Kedavra" together before firing the slug, and it is best for the opponents to hear it. Then, the opponent will definitely fall...

In this way, in this ignorant age, the opponent is likely to suspect that the musketeers of the North Sea State have cast magic. Otherwise, everyone also uses muskets, and the appearance is similar, so why are yours so powerful?

The children are also very stupid and loyal. Marin asked them to shout this shameful slogan together, and it was actually carried out to the letter. Seeing these thousands of teenagers yelling "Avada Kedavra" solemnly together, Marin himself felt embarrassed and wanted to cover his face in shame.

But considering that everyone doesn’t know what this means, so I hypnotized myself:

"I'm not embarrassed, it's others who are embarrassed... I'm not embarrassed, it's others who are embarrassed..."

In fact, there was no embarrassment at all. Because I don't understand, I don't know why it is embarrassing. Therefore, Marin himself was embarrassed in vain.

Seemingly addicted, Marin put this set on the artillery again. This time, the victim is Saul...

In order to enhance the sense of ritual and give people a feeling of casting magic, Marin asked Sauer to dance for a while before firing the cannon, and then put his hands on top of his head. Finally, shout out "In the name of God, Marlin, the god of war, will destroy you on behalf of the moon!"

Then, the match was lit, and the launch...

This time Saul was really embarrassed, because not only did he shout "spell", but he also wanted to dance to the gods!

To think that he is the "commander of Jinyiwei" of the Beihai Kingdom, a murderous figure who can make children stop crying in the army and in the country, and he is asked to dance to the gods, which is more heartfelt...

Bixin actually doesn't understand what it means, it's not embarrassing, but it's too embarrassing to be a great dancer who is similar to Nicholas Zhao Si's street dance moves...

The point is, Marin only let him dance alone, there are 7 people in a cannon squad, and he is the only one who dances Zhao Si hip-hop...

But Marin also has plausible arguments-I trust you in the entire artillery squad, don't worry about letting others do this...

If you change to an officer with a simpler mind, you may really believe it. But who is Saul? Those who followed Marin before he made his fortune knew how doggy their "boss" was. In addition, he has served as Marin's "black glove" for a long time and knows a lot of inside information. Therefore, Sauer didn't believe that this embarrassing "Zhao Si hip-hop" style dance master was useful. His own boss likes to confuse people the most, so he is 70% sure that this is fooling outsiders.

However, when the boss spoke, he dared not not dance. So, a 1.77-meter-tall man, imitating Nicholas Zhao Si (demonstrated by Marin himself), trembling his legs, and kicking the enchanting back kick, is really eye-catching...

As for the heart-to-heart comparison and shouting "on behalf of the moon to destroy you", Shaoer is not embarrassed. Because, he has never seen "Sailor Moon\

,"I didn't know that this was the little girl's trick.

But Marin probably got addicted to playing, not only let Saul yell "destroy you on behalf of the moon", but also put a moon on Saul's forehead. In this way, the young Bao Qingtian who looks like Brother Jie... Well, it is Brother Jie with big nostrils, not the brother Jie who "Don't want Jie"...

...

Just like that, Shaoer painted the moon on his forehead, danced Zhao Si hip-hop with a sense of shame, and yelled "destroy you on behalf of the moon"... Not to mention, this guy's skin is a little tanned, he is really a teenager Qingtian feels...

After a whole set of shameful actions and words, Sauer ignited the fuze for shooting training.

In order to cooperate with the drill, Marin specially cast hundreds of iron cone shells and beeswax "hats" for Sauer to aim at the simulated wooden city gate bombardment. Then, stuff it into the gunpowder keg and press open the city gate...

But during the drill, Marin discovered a big problem-the single-headed shell has strong penetrating power, and it can punch a hole with one shot. However, because the ballistic trajectory is too straight and the penetrating power is too strong, the hole made is only slightly larger than the diameter of the single-headed shell itself, and there is no big hole.

Although two more shots can punch a big hole, which can be put into a gunpowder barrel. But the problem is that the artillery of this era is a retreating artillery, and the entire artillery carriage retreats after firing, requiring the artillery to step forward and reset. However, it is inevitable that there will be errors in the aiming point of the artillery after the reset. However, if there is an error at a long distance, the result is that the landing point of the second shell is very different from the landing point of the first shell. It is difficult to make large holes next to each other, and can only make small holes one by one, which cannot be stuffed into the gunpowder barrel.

For example, the caliber of a 12-pound gun is 93 mm, or 9.3 cm. For a 225L oak barrel, the diameter of the thickest waist reaches 678 mm, which is 67.8 cm, which is more than 7 times the diameter of a cannonball!

If the aim is good, three or five shots can make a hole big enough to accommodate the powder keg. If the aim is not good, the ghost knows how many rounds will be fired... and Marin is generally unlikely to carry too many such confidential shells, so this is a very troublesome problem...

...

"It would be great if there was more powerful gunpowder. Just a small barrel with a diameter similar to that of a shell can squeeze open the city gate..." Shaoer said regretfully.

"More powerful gunpowder?" Marin touched his chin and thought for a while...

Smokeless gunpowder as a propellant does not seem to be very popular. For safety and no accidents, Malin specially added paraffin and camphor as stabilizers. In this way, the power of gun cotton is greatly reduced. Used to blast city gates, the diameter of 7 times the difference is obviously not powerful enough for a whole barrel of black powder.

"So, the only way to squeeze out Nobel's diatomaceous earth is to squeeze out Dana's medicine?"

Dana's pressed medicine is very simple, that is, the digested dry oil is absorbed by diatomaceous earth. The detonation speed of this thing reaches 7700 meters per second, which is more than ten times that of black powder at 500 to 600 meters per second. In this way, the diameter difference of more than 7 times was erased at once. Even, the power has been strengthened.

Most importantly, there is no need to fire multiple times to make a big enough hole. With just one shot, a bullet hole can be inserted into Knott's diatomaceous earth to extract medicine.

Why is the pressure of the gun so high in later generations? It's not that the propellant has been replaced with a high-velocity propellant. During World War II, the bore pressure of the battleship's 460mm main gun was not as good as that of modern 125mm tank guns. Therefore, due to the use of powerful propellants, the requirements for gun steel are extremely high. Japan, which was able to produce 460mm naval guns during World War II, was unable to produce tank barrels that could withstand high chamber pressure. There is no way, the difference in detonation speed is too large, and the requirements for steel are too high.

In addition, the key diatomaceous earth squeezed medicine is also easy to get...

For reasons of rivers and crabs (chapters 847 and 848 are missing like this), the detailed process cannot be written. But digested dry oil is made by processing nitric acid and oil, and it is easy to get. And diatomaceous earth is easier to get...

"Wait...it's very easy to do...this is not good..."

Marin will not make a powerful medicine that is too easy to make, why? Build technical barriers! Do you think that the reason for the high-tech weapons that the old Americans will use in later generations is because wars really need so many high-tech weapons? No, in fact, Laomei is only raising technical barriers to prevent other countries from competing with him. Well, so do my rabbits. The higher the technical barriers, the more beneficial it is to a big country. In addition, high-tech weapons have high prices and high profits...just like the pharmacies in later generations who deliberately do not sell low-priced medicines, because the profit of 10 boxes of low-priced medicines is not as good as one box of high-priced medicines...

...

The same is true for Marin's technical barriers. If the enemy cannot be created, I have it. Who can be my opponent? The problem with Nuoziri's diatomaceous earth extract is that it is too easy. As long as you master the technology of nitric acid, it is too easy to convert glycerin. This is not in the interests of Marin, so Marin directly abandoned the diatomaceous earth version and changed to an advanced version of Knott's press that is more complicated - squeezed gum.

Knott's gum is very simple, just replace diatomaceous earth with gunwool. Collodion can be dissolved in glycerin to form a stable jelly. This is better than the diatomaceous earth version, because what diatomaceous earth absorbs glycerin is just adsorption, not really absorption. After a long time, the glycerol is easy to separate from the diatomaceous earth, which will cause danger again. Therefore, the later version of Knott's Gum Press is a better choice.

As for Marin, the gun cotton used by Knott's rubber is not available in other countries, and he doesn't understand the principle. As long as nitric acid is produced from any glycerin, it is possible to produce it. As for gun cotton, even if it happened to come out, they didn't know what it was or what it was useful for. After all, there were no serious chemists in this day and age.

Knott's rubber pressing can definitely set up insurmountable technical barriers, making it difficult for other countries to obtain.

Moreover, this thing is extremely powerful. There is no need to stuff it into the hole in the city gate like a black powder barrel, as long as it is attached to the city gate, it can crush the city gate. Of course, a small country is better if it is stuffed in and squeezed out. It can overturn the sundries in the city gate and clear the obstacles for the troops to enter the city.

"Okay, it's up to you, Knott's Gum Squeeze!" Marin planned to make a batch of Knott's Gum Squeeze himself. It doesn't need much, just enough to squeeze open a few city gates. For example, for this expedition to the Grand Duchy of Moscow, it is enough to bring a few copies...
