Now he told this matter out of the matter, and wanted to publicize it on a small scale. After all, the popularity of things that have never been before is not a matter of one or two days, and it must be popularized from top to bottom.

In any dynasty, the emergence of gunpowder weapons on the battlefield indicates a series of changes in military history. The transition from the stage of using cold weapons to the stage of using firearms. The initial form of gunpowder used in weapons was mainly to utilize the combustion performance of gunpowder. The early gunpowder weapons recorded in "The General Yao of Wu Jing" have not yet left the category of arson weapons in traditional fire attacks. With the development of gunpowder and gunpowder weapons, the explosive performance of gunpowder has gradually become excessive.

Li, who had studied later, knew that gunpowder made of potassium nitrate, sulfur, and charcoal powder was called black gunpowder or brown gunpowder. This mixture was very flammable and burned very violently. If the gunpowder burned in a closed container, it would explode. When the gunpowder burned, it could produce a large amount of gas (nitrogen, carbon dioxide) and heat. The volume of solid gunpowder, which was originally very small, suddenly expanded and increased to several thousand times, the container would explode. This is the explosive performance of gunpowder. Various types of firearms can be made using the properties of gunpowder combustion and explosion.

But Li Qing knew that these principles were hard to understand with the generals under his command, and could only say something they could understand. In the further step, Li Qing had already written out all the weapons suitable for this era and their manufacturing methods.

One of the things that Li Li admired the most is that it was a popular thunder in the Song Dynasty.

After the detonation of the thunder, it can blow the pig iron shell into pieces and penetrate the iron armor.

There are two types of thunderstorm. One is to ignite with fire, which is fired by a trencher and exploded in the distance; the other is to ignite with fire, which is to explode on the spot, such as throwing it from the city wall downwards when defending the city, which is equivalent to grenades in later generations.

It uses an iron can as a shell, built-in gunpowder and other objects. After ignition, it throws it to the enemy. The cannon fires and its body is like thunder. Even a hundred miles away, it can be heard. "Above half acre, the fire ignites armor and iron, all of which are penetrated." In other words, its explosion area is more than half acre, and the broken shrapnel can completely penetrate the iron armor.

In fact, in Li Qing's opinion, this kind of thing is quite technically unrelated. As long as it can be made, it can be used even by people who have never been exposed to it.

Sure enough, when everyone saw this thing, they nodded repeatedly, although they didn't know what the real effect would be after the thing was made.

There is also a weapon that Li Wen is more optimistic about, called the flying musket.

This flying musket is a bamboo paper tube-type firearm, which is an equipment of the army in the past. At that time, the Song Dynasty often fought with the Jin Dynasty. The Jin Dynasty learned the production method of the Song Dynasty and invented this flying musket. The barrel of the flying musket is more than two feet long and is made of sixteen layers of yellow paper. The barrel is filled with willow charcoal, iron slag, porcelain powder, sulfur, arsenic, etc. Once this thing plays a role, it will cause great pain to the enemy.

Flying muskets are a rocket weapon. According to the research of scholars in previous lives, this kind of flying musket is a rocket weapon, and its style is a gunpowder barrel with two inner parts tied to the upper side of a long spear. The rocket relies on the reaction force generated by the combustion injection of the rear gunpowder in the gunpowder cartridge. When it advances to a certain distance, the gunpowder in the front is ignited, and the gunpowder in the front sprays sparks forward, causing damage to the enemies in front. According to records, the sparks emitted "fired more than ten steps of money burning, and people dare not approach it."

The reason why Li Neng knew about this flying musket was because he knew that in the history of his previous life, when the Mongolian army attacked places outside the territory of China, they had actually mastered these weapons.

It was precisely because they went out that they passed on such awesome things from China to the West, and finally passed on gunpowder technology to the Western world was the third expedition launched by the Mongols in their previous lives. This expedition was launched by Hulagu, the younger brother of the Mongolian Khan Mongge who eventually died in Diaoyu City. The number of troops was very small compared to the previous two times, only 30,000, but the firearms carried on this expedition were the most advanced in history. The "Guller Army" of the firearms unit was led by Guo Kan, the grandson of Guo Baoyu, who is more famous in Chinese history.

During this expedition, most of the siege operations were firearms. From the Qidubu Castle in northeastern Iran, Bagh in Iraq to Aleppo in Syria and other cities in siege operations, the Mongolian army used a large number of firearms in order to conquer the city with small casualties in a short period of time. In the end, Hulagu established the Ilkhanate in this area.

It was during this Western Expedition that the gunpowder technology of the Mongolian army was understood by the world of the Middle East. Later, in the war between the world of the *** and the Christian world of Europe, Europe gradually mastered the technology of gunpowder manufacturing. After the 14th century, Europe gradually used gunpowder. The earliest existing image of the use of firearms in Europe appeared in a Latin manuscript "His Majesty the Smart and Wisdom King" written around 1326.

It can be said that the reason why the Mongols achieved brilliant results in the Western Expedition was that in addition to the superb tactics of the Mongols, the elite swords, guns, armor and the large number of war horses and livestock brought by the developed animal husbandry industry, firearms are also an important part.

But one thing is that gunpowder has brought great changes to the world because they spread to the West.

This is also the reason why Li Qing has been hesitating. Although gunpowder can be found and played a role in his hands, once the war begins in the end, this technique will definitely not be able to be covered, and it will be possible for others to know sooner or later.

This is in line with the old Chinese saying, "It's not fat first to be fat, but then fat will collapse the kang. After you invent it, it's another matter to say whether this thing was developed in your hands.

This is the problem with the Tang Dynasty. They always felt that they were quite strong, so they must be the slowest to accept new things, because they need to change themselves if they are not in a position.

Li Qing knew that once the Tang Dynasty fell into such a situation, it would be better not to invent this thing. How did the Qing Dynasty in his previous life perish? Isn’t it because he thought he could do it, but in the end he proved that he could not do it?
