When Hitler heard that Li Puyu provided a new submachine gun instead of the active submachine gun equipped by the African People's Liberation Army, he naturally expressed some displeasure, and said: "Li, what I hope to get is the active submachine gun that your African army is equipped with, not the defective products designed by you in Africa that you don't like to use." Ran Wen ???? ?? ? ?ｅｎ`ｏｒｇ”

Li Puyu was overjoyed when he heard this, and said with a smile: "Mr. Hitler, our Light Weapons Design Bureau has designed a total of three submachine guns, namely the QBQ 37 submachine gun, which is the submachine gun in active service in our army. There is also a QBQ38 submachine gun used by the militia. The last one is the RM38 submachine gun. Of the three, the QBQ38 submachine gun is the cheapest, costing only a measly 50 cents. However, although the QBQ 37 submachine gun is an active submachine gun equipped by our army, because our army did not have a second submachine gun to choose from at that time. In desperation, the most perfect submachine gun is the RM38 submachine gun, the two letters of RM make us the initials of the word "people" in Chinese pinyin. ”

Hitler still said with a look of disbelief: "This is your perfunctory words, God knows what you Africans are doing." ”

When Li Puyu saw that Hitler didn't believe his words, he said, "Okay, Mr. Hitler, since you don't believe me in my bet?" ”

Hitler was immediately interested and said: "What is your bet on Africa?" ”

At this time, Li Puyu put his face in front of Hitler and said: "What do you Germany want? ”

Hitler then replied: "I want all the relevant technology of the Apocalypse tanks equipped in your African armies, I don't know if it is okay?" ”

Li Puyu returned to his seat, picked up an apple, took a bite and said, "Yes, but what is your German bet?" ”

Li Puyu said with a smile at this time: "It's very simple, I just need your German airship technology, okay?" ”

The reason why Li Puyu asked Germany for airship technology is not because the Red Alert system does not provide this technology, but because Germany's airship technology is now in the leading position in the world in this era. But his suspended gas is combustible hydrogen. Once something happens, it's a huge fireball. The airship of the Red Alert system uses helium, an inert gas, which is much more advanced than the Zeppelin. Li Puyu just wanted to make Hitler's flesh ache and nausea. But what Li Puyu didn't know was that after the 1937 Hindenburg air crash in Germany, people generally lost faith in this mode of transportation, and Hitler also turned away from him.

After hearing this, Hitler said to Li Puyu: "Okay, it's totally possible. ”

In exchange for this airship technology that he doesn't like, he is the most powerful of this Chinese kid, and it is cost-effective to look at the technology himself. So Hitler simply agreed.

At present, the submachine gun equipped by Germany is mainly MP36 submachine gun, this submachine gun is the ancestor of the German MP38/40 submachine gun, the 36 submachine gun is very similar to the MP38 submachine gun, but the magazine of the MP36 submachine gun is tilted 30 degrees to the left, which is convenient for the left hand to hold the magazine. When designing the MP38 submachine gun production, in order to simplify production, the 36 submachine gun could choose a single and 36 submachine guns, and the number of 36 submachine guns was very small, and only two remained. The famous MP38/40 submachine gun was only equipped with a small number of troops, and the German army was only equipped with thousands of this gun before the outbreak of the Polish campaign in 1939, and almost all of them were used by German armored forces.

The MP40 submachine gun that Li Puyu supplied to Germany was the MP40/1 type, and in order to meet the needs of well-made weapons during the war, simplifying the production process and reducing production costs were the main issues considered by the military. After the Polish campaign, in order to further simplify the production process and improve production efficiency, the German industrial enterprises improved it again in 1940 according to the actual combat experience, so that it had lower cost, fewer man-hours and higher safety. 40 with a large number of stamping, welding process parts instead of MP38 machining process parts, reduce costs, standardized parts in the factory separate production, unified assembly in the assembly plant, easy mass production, even some non-military enterprises can subcontract the production of parts, with good processing economy and parts interchangeability. Between 1940 and 1945, more than a million MP40 submachine guns were produced. The MP40 submachine gun, and its prototype, the MP38 submachine gun, use the principle of free bolt action, using 9 mm caliber pistol cartridges and a straight 32-round magazine feed. Tubular receiver with an exposed barrel. The grip guards are all plastic. The simple folding stock made of steel tubing folds forward under the receiver for easy carrying. The hook-like shape of the barrel seat allows the barrel to be hooked by the armoured vehicle's perforation when firing outward, avoiding the barrel from falling back into the vehicle body due to recoil or vehicle turbulence. The gun has a simple structure and excellent design, and the disassembly and combination of the gun do not require special tools, which is very convenient.

The soldier holding the MP40 later became a symbol of the German people in World War II. In fact, the earliest MP38/MP40 submachine guns were only used by armored troops and airborne troops, with the increase in production, MP40 has been widely equipped with grassroots troops, and has become a popular automatic weapon for combat units, not only equipped with armored troops and paratrooper units, but also in the proportion of equipment in infantry units is also increasing, always preferentially distributed to front-line combat units. But in fact it is not as widely used as people think. Objectively speaking, the MP40 is an epoch-making weapon, but it is not a perfect weapon.

The P40 eliminates the traditional wooden fixed stock, handguard components and barrel guards and other bulky and bulky structures on the gun body, and the main components are pressed steel sheets, and even the only time-consuming wooden stock is replaced by a steel folding stock. There is no complicated process for the whole gun, and the steel sheet pressed gun body can be manufactured at will in the assembly line of the general factory, and the general junior technical workers can be manufactured by relying on tools; The lower part of the receiver is made of very lightweight aluminum. Even for the surface of the gun there was no polishing, in a word, all complicated processes were canceled. Thanks to this design idea, the MP40 can be manufactured in large quantities in large and small factories all over Germany.

In addition, it has extremely high shooting accuracy, so Li Puyu took out this weapon and fought with Germany.
