On this day, the thunder rumbled among the mountains located in the northwest of Mt. Lei, and it continued continuously. Pen, fun, pavilion www. biquge。 info

As for how many spring thunders the dragon fought on this day, although it is uncountable, but the people in Xishui County are the people in Xishui County, but they are happy to hear it, after all, "spring thunder works hard, and the sky is in the sky" - "Hanshu Xuchuanxia".

Naturally, no one knew that the first batch of 216 artillery scientists of the Thunder God Academy officially graduated on this day, and the first generation of the Thunder God Force's mounted artillery was also finalized and began mass production today.

The first generation of Thor artillery is not complicated, but it is simply divided into three models: the light gun is inscribed with the tiger's head, the total length of the gun body is one zhang and two feet, the inner diameter is four inches, and the thickness of the gun wall is about two inches. The length of the heavy gun is the same as that of the light, but the inner diameter has been increased to five inches, and the thickness of the gun wall has also been increased to five inches; As for the long-range artillery, it adopts a one-foot six-foot gun body, with an inner diameter of three inches and a gun wall of six inches.

As for the inner wall of the barrel, it is still a smoothbore structure, not that Huang Jie has never seen the structure called rifling in his dreams, but that today's casting process has not yet realized this process. Even he had naturally seen iron cannons and steel cannons in Qimeng, but the reason why he still used all-copper casting was that the iron casting process was immature at this time.

However, because he had seen a lot of strange dreams, he did not continue to follow the old path of front-loading gunpowder, but directly used fixed-loading shells in one step. The length of the shells is fixed to be two feet, and the three types are equipped with gunpowder and warheads, and as for the warheads, because the technology is not yet mature, there are quite a few models. For example, there are two kinds of light artillery: round iron and round explosives, iron is an iron ball made of pig iron, which is very sharp for siege, and the explosive is the structure of earth-shaking thunder, but because the trigger-type detonation fuse has not yet been developed, the buried open flame fuse is used, and the explosion principle is the same as the second kick.

And there are as many as four kinds of ammunition for heavy artillery, in addition to iron and explosives, there are also scattered bombs and poisonous smoke bombs, and there is no need to say that scattered bombs are not to say, he refused to poison smoke bombs at first, but after Xue Xian took out a few copies of his improved poison smoke bomb formula, Huang Jie had to admit that this ammunition was still very effective in large-scale battles to attack and defend cities, and it was enough to have scattered bombs against cavalry.

It's not that Huang Jie doesn't want to equip it with explosives, it's just that the amount of long-range artillery is too large and the pressure in the hall is too strong, and the explosives that use the two-kick detonation method are extremely unsafe when fired, and within ten rounds, at least one or two rounds will explode directly in the barrel, and two or three rounds will explode in the air during the flight of the shells, so they are simply not equipped for the time being, and leave it until the research is mature.

In general, although the copper cannon cast with cooked copper is easy to overheat in the process of firing, and because the texture of the copper is too soft, each shot will cause the barrel to expand, the shooting accuracy and range drop very quickly, and the life as a weapon is too short.

As far as the current situation is concerned, the casting cost of a light copper cannon is 2,000 catties of copper (about 1,200 copper coins), 3,000 catties of heavy artillery and long-range guns, and the manual cost is only about 500 catties per cannon, which is relatively cheap.

Relatively speaking, the price of cannonballs is slightly more expensive, because saltpeter now belongs to the official materials of the Great Song Dynasty, and the official kiln fire-smelting saltpeter with better quality is even more scarce, so the price of this cannonball, not counting the reusable shells and cheap iron, which are embarrassed to quote money, gunpowder alone can be worth ten dollars.

This is because as far as China is concerned, there are very few natural saltpeter deposits, and most of the saltpeter used by the people is artificially refined, and the natural price is very high. It is important to know that saltpeter in nature is often formed by the decomposition and oxidation of nitrogen-containing organic compounds in the soil under the action of bacteria to form nitric acid, and then the potassium in the soil. Therefore, whenever the autumn is high and cool, it is usually precipitated in the form of a skin shell or salt flower, covering the corner of the surface wall, this is the so-called ground frost, scraped and swept up called "nitrate", the northern provinces of our country are widely produced, but the nitrate content in different regions is obviously different.

As for the fire nitrate used in Thor Run, it is naturally extremely pure, and it has been purified many times, and the price is naturally staggering.

In addition, in addition to the Thor artillery, the Ling family father and son also made some improvements to the palm thunder and gunpowder arrows in their spare time, but in the end, the father and son raised the research and development of the Thor artillery to the height of "the best in their lifetime", so they also threw these bits and pieces of work to Xue Xian.

Not to mention, Xue Xian, this old guy is also a quick-thinking master, since he can come up with the idea of burying fine iron beads in the improved version of the palm thunder to increase the power, he can naturally put his cleverness into the research and development of gunpowder arrows. Since then, he has developed three types of gunpowder arrows, a crossbow that can be fired from a bed crossbow, a spontaneous fire that fires on its own when ignited, and a flamethrower-shaped that can be strapped to an arrow and fired intensively.

It's just that these things he made have become gadgets in front of Thor's artillery, and it is difficult to find a chance to show their power.

And this time, the reason why Huang Jie brought Zhao Liangsi to watch the graduation ceremony of the second dragon in February was also because he had a premonition that some things should also be open and honest.

This night, in the auditorium of the Thunder God Academy, more than 200 people were sitting in danger, the old seed master was kneeling on top of the chief in military uniform, Huang Jie and Zhao Liangsi were divided into two sleeves, and everyone came to listen to the seed master and the graduates of the first phase of the artillery department of the Thunder God Academy to follow the sermon.

I also heard that the seed master was full of anger, and he spoke to everyone in Bianliang with a northwest Qin accent: "Artillery!" Today's first stand, there is no precedent to follow, an unprecedented method of war, and the advantages and disadvantages are unknown! However, the old man has seen in the past 60 years of military service, Thor will be the heavy weapon of the army and the country in the future, and it is not without precedent to form an army with a single weapon. ”

Listening to the firm tone of the master Dao's affirmation of the new branch of artillery, Huang Jie naturally had smoke (and honor), but while recalling the might of the artillery he saw in his dream, he couldn't help but think of the two sharper weapons he had seen.

These two weapons of mass destruction, one was originally named by him as a gun carriage, and later after his repeated study of the strange dream, he also knew that this thing should be called a "tank", but the principle of carrying a cannon on the car was understood. The other one is called the iron bird by him, but until now, he still can't understand the reason why this iron bird can take off.

When Huang Jie thought about whether he should be able to climb the technology tree of the tank now, he also heard a collective roar in his ears, but the final sermon of the Planter Dao was finally completed.

But seeing that the old man stood up suddenly, he raised his sword in his hand and shouted: "Great Song Wansheng!" (To be continued.) )
