Firearms and weapons were born in China, but they were not carried forward in China, but developed rapidly in Western countries.

Although Zhao Zhongyao is not an expert in the development of firearms, he has been reborn from the 21st century into this parallel space of backward science and technology.

For the guns of the twenty-first world, even if Zhao Zhongyao is a layman, he will also hear about some very famous guns.

Zhao Zhongyao knows that on the earth of the 21st world, the most famous gun is the AK-47 assault rifle produced in Russia.

This kind of gun can be said to dominate the entire gun world, and no matter the army of any country, there may be such guns.

This firearm is the most manufactured and imitated firearm on the planet in the 21st century. There are probably hundreds of millions of these guns in the world, which are used in various regional conflicts and large-scale wars.

The AK-47 assault rifle is an automatic rifle designed by the Russian firearms Kalashnikov. AK is (acronym for "automatic rifle") Kalashnikov automatic rifle created in 1947. It is the first generation of assault rifles in Russia.

The AK-47 is an assault rifle that has a shorter body and shorter range than World War II rifles, making it suitable for close-range combat. Using the principle of pneumatic automatic, the air guide tube is located above the barrel, and the bolt action is pushed by the piston, and the rotary locking bolt is locked.

The AK-47 fires 7.62x39mm 1943 Intermediate Power Cartridges, fed by a 30-round arc magazine, with a safe/fast handle on the right side of the receiver, semi-automatic or fully automatic firing options, and a pull handle on the right side of the receiver. The AK-47's bolt action is reliable, and its mechanical structure ensures that it continues to function normally even when firing continuously or when foreign objects such as dust enter the gun. And it can maintain quite good performance in extremely harsh environments such as deserts, tropical rainforests, and severe cold, and its structure is simple, easy to decompose, easy to clean and maintain, and easy to operate.

The main drawbacks of the AK-47 are that the muzzle rises heavily during fully automatic fire, the bolt frame backseat hits the bottom of the receiver, the design of the bolt ejection port makes it difficult to install Picatinny rails, and the design of the receiver cover results in a short aiming baseline. The design of the sight is not ideal, the recoil of the gun is large, and other defects, which greatly affect the shooting accuracy, it is difficult to shoot accurately beyond 300 meters, and the accuracy of continuous fire is even lower, in fact, it can only meet the requirements of close combat based on encounters.

The reason why this gun can be carried forward is inseparable from World War II. War was often the catalyst for the invention of guns and a breeding ground for the emergence of new weapons.

World War II, as the most famous war in the history of human warfare, participated in the war with the largest number of countries and armies. Naturally, many new weapons and equipment will appear.

Like the well-known tank armored vehicle, this kind of weaponry was born from the flames of World War II. Of course, during the First World War, there were also tanks as weapons and equipment, but at that time, the tank was just a movable pillbox, whether in terms of mobility. In terms of fire system configuration, the tank at that time was just a 'baby'.

And really let tanks and armored vehicles. It began to be used on a large scale in warfare, of course, during World War II.

The tank was invented by the British, and it was of course German that could be used in warfare and showed excellent performance.

It was with the power of tanks and armored vehicles that Hitler was able to carry out his famous method of warfare, 'blitzkrieg'.

Suffice it to say that there are no tanks and armored vehicles. Hitler could not have carried out his blitzkrieg, nor could he have quickly conquered all of Europe. Become the hegemon of Europe for a while.

All this is precisely because Germany first developed tanks and armored vehicles into conventional weapons in war, and was able to improve tanks and armored vehicles in many aspects, so that this 'spear and shield' combination of the product. It has been greatly popularized and applied in the war.

It was with his own ironclad torrent that Hitler was able to sweep across Europe at lightning speed without an opponent.

In the end, he arrogantly wanted to conquer the whole world, so he frantically tore up the non-aggression pact signed with Russia, and brazenly launched a war of aggression against Russia, one of the most developed countries in the world at that time, in a vain attempt to overthrow the newly established red regime.

Hitler, with the incomparably huge military power he had accumulated through the European theaters, began to attack Russia frantically, and he clamored for the destruction of Russia in three months.

At first, everything went well, his troops attacked quickly, and the blitzkrieg once again showed its power.

In less than two months, his troops had reached the Staringrad region, not far from Mosco.

Originally, Hitler thought that this small city would soon be breached. But it wasn't what he imagined.

God already doesn't like him. An unprecedentedly cold weather put an end to Hitler's ambition to dominate the world.

All his heavy tanks and armored vehicles, when they arrived, were at the end of the crossbow. The extreme cold turned these behemoths that once swept across Europe into a pile of scrap metal, and the engines of all tanks and armored vehicles stopped working. They can only lie on their stomachs and remain motionless, and they can no longer exert their unstoppable power.

Not only have these tanks and armored vehicles lost their former power, but even the German soldiers were in trouble, their rifles were no longer effective in the extremely cold conditions, and many guns had been frozen by the extreme cold and could not be used at all.

Many of the soldiers also suffered from serious illnesses and were unable to fight at all. The entire army was defeated.

In this way, the torrent of ironclad that once swept across Europe finally came to an end, and it was no longer possible to move forward.

Hitler's powerful blitzkrieg was no longer what it once was. His previous clamoring for the destruction of Russia in three months has also become a big braggart.

This time, naturally, the Russians were given a chance to breathe, and under the correct leadership of Stalin, they quickly launched a famous battle to defend 'Stalingrad' in the history of World War II.

Contrary to these situations encountered by De Jingzhi's troops, the Russian troops, because they were locals, had lived here for a long time, so they naturally adapted to this harsh weather for a long time. Even their weapons are fearless of this weather. (To be continued......)
