At This Moment, All Mankind Thinks That I Am The Eternal!

Ji Han said a few words

The next path of the Ming Dynasty has been thoroughly analyzed!

Although it is not appropriate for Chongzhen to go to war at this time, he insists on expanding the army, reforming the military system, building ships, and distributing fields to households. It is believed that results will be seen in less than half a year.

At that time, Chongzhen will become the toughest overlord in the Ming Dynasty and even in the world. He will sweep whoever he wants, and he will reform whatever he wants.

"Finally, let's talk about the transformation of the Ming Dynasty firearms!" Ji Han happily lit a cigar, while puffing the clouds, he said: "Although the Ming Dynasty firearms are now leading the world, it is not enough, far- Not enough!

"The reloading of the flintlock gun is too slow, the stability is poor, the range is poor, the fuze of the mortar is not enough, and misfires or misfires often occur, all of which have to be extensively modified!"

Speaking of this firearm, Chongzhen Yingzheng immediately became interested!

The two stared at Ji Han with burning eyes, as if they were afraid of missing a word.

After all, this firearm is the topic that makes them most concerned.

"First of all, let's talk about the shells of this mortar. The current shells are too backward, and there is a long lead. After the lead is ignited, it is inserted into the barrel of the gun and fired. It is too slow and unstable! 35

"The point is that gunpowder is likely to remain after each shot, and the gun chambers have to be cleaned frequently, which is very inconvenient! 99

"So we had to make an all-metal shell, and after it was inserted into the chamber, it could be fired on the spot, completely without ignition!

"If you want to do this, you must use a mercury primer, which is an explosive that is more sensitive than gunpowder. It can replace the lead as an igniter, so that the artillery can be fired even in rainy days!

Ji Han is afraid that everyone will not be able to hear clearly!

So I used my mobile phone to search for some pictures of modern cannonballs, so that everyone can see what this all-metal cannonball looks like.

"Sir, how can this shell be ignited without a lead?" Chongzhen was stunned, unable to understand for a while.

"Because of mercury!" Ji Han explained, "This cannonball is no different from your current cannonball, except that it is loaded with some smokeless powder, and then a primer is placed underneath!

"The mercury is placed in the primer, the primer is cleverly designed, and a primer cup and a concave card holder are placed inside!

"After the mortar is slightly modified, it is only necessary to reserve a firing pin on the barrel. When the shell slips from the barrel, the primer will hit the firing pin hard!"

"When the primer cup of the primer is hit, it will hit the concave deck, and the collision of the two will ignite the mercury and then ignite the gunpowder!"

As Ji Han spoke, he wrote and drew on this piece of paper. He spoke very clearly, and everyone understood at once!

It's actually not that difficult!

The design of the primer is also very simple, it looks complicated, but in fact there are only two or three parts, and everyone can understand it after taking it apart!

"The crux of the matter now is the production of mercury mercury!35 Ji Han continued: "This thing is a bit complicated, it involves some chemical knowledge, first you have to find green alum!35

"Green alum?" Chongzhen was taken aback.

"Yes!" Ji Han nodded: "This is a natural crystal, also used for medicinal purposes, also known as alum, many pharmacies have it, and it is also recorded in the Compendium of Materia Medica! 95

"When it melts at high temperature, it can obtain sulfuric acid, which can corrode iron and is very dangerous! Once saltpeter is added, it can become nitric acid!"

"The reaction of nitric acid and mercury can produce mercury nitrate, and finally mercury nitrate is added to ethanol, that is, a high concentration of alcohol, to produce mercury fulminate!"

"This thing will explode with a little collision, and it usually has to be passivated with oil and fat and preserved!

Ji Han explained patiently!

Although Chongzhen didn't quite understand it, he wrote it down one by one.

All these things can be found in the Ming Dynasty, such as green alum, saltpeter, mercury, alcohol, etc. You can find as much as you want!

Go back and experiment a few times, and you can always develop it!

Then it is equipped with a simple primer device, and since then, the mortar shells of the Ming Dynasty will no longer have to be lit with torches!

・・Ask for flowers・

Just stuff the shells into it, and it will be fired with a bang. Thinking about it, it's shocking.

"Sir, I will let the craftsmen develop it when I go back!" Chongzhen promised excitedly!

"Um!"

Ji Han nodded in satisfaction.

He has no doubts about whether the Ming craftsmen can successfully develop it, because he never dared to underestimate the wisdom of the ancients.

The general direction and method are provided to them, and these craftsmen will persevere in research, and success is a matter of time.

After all, many chemical phenomena appear in daily life, so why is it difficult to study them seriously?

.0

"Sir, after the problem of this shell is solved, the power and firing speed of the mortar will be greatly improved! 35

"Can this fulminate mercury also be used on bullets? If it can be made into a bullet that can be fired without ignition, then the firing speed of the firearm can be greatly improved.

Ying Zheng was on the side and suddenly asked this question!

Ji Han smiled in amazement and said: "Oh, Lao Zhao, you can have a good brain, in fact, firearms in later generations are indeed like this, they don't need to be ignited at all, just pull the trigger to fire bullets, and they can shoot dozens of rounds with one breath. Not surprising!

"so much?"

"Dozens of breaths in one breath?"

"My God, what kind of artifact is this? 35'

Everyone was stunned. If it wasn't for the fact that Ji Han never bragged, everyone would have thought it was a wild talk.

"However, the meal has to be eaten one bite at a time, and the gun has to be built step by step, so there is no rush!

"At the current level of the Ming Dynasty, it is not enough to develop all-metal bullets. The difficulty is that the production of bullets is more delicate and compact than cannonballs, and it is more difficult to mass-produce!

"But Chongzhen, you can let the craftsman try to make this shotgun when you go back!

Ji Han's proposal immediately surprised Chongzhen!

Shotgun? What kind of gun is this? Beg.
