Anti-Japanese War, weapons designer at Fengtian Arsenal

At this time, there were still some overtime workers in the factory who were leaving get off work one after another. Li Qinwu blended into the crowd without attracting anyone's attention.

He did not choose to leave through the factory gate because the soldiers at the gate would conduct random checks to see if the workers were smuggling any contraband.

Although these soldiers were very lazy and only checked one or two out of hundreds of people in the past, Li Qinwu did not dare to take the risk.

He took a detour to the wall and walked 300 meters into the factory along the wall, arriving at a place covered with weeds. There was a hole in the wall blocked by weeds. The hole was chewed out by a small predator. This was what Li Qinwu discovered while wandering around the factory, and it came in handy for him.

He sent the weapon out of the hole and then swaggered out of the factory with the crowd.

After retrieving the weapon, he did not go home, but ate at a noodle stall outside the factory.

While eating, he stared straight at the factory gate, as if searching for something. Finally, when it was just getting dark, Li Qinwu saw the target he was looking for, Liu San.

This guy took off his military uniform and walked out of the factory wearing only a shirt and a short jacket. Li Qinwu knew that this guy would slip away, so he deliberately blocked him here.

Normally, officers like Liu San need to work night shifts at the factory and must sleep in the factory dormitory. However, those who understand the military discipline under the warlords know that they will sneak away and go home to sleep every day.

Li Qinwu followed this guy to a residential area in the city. Liu San's house was also a yard, similar to Li Qinwu's, and also had a wall. Liu San was considered middle class in that era.

Liu San went home and closed the door. Li Qinwu approached quickly and listened at the base of his wall for about 10 minutes. After confirming that he was the only one living in his house, he memorized the surrounding terrain and chose to go home first.

After arriving home, Li Qinwu lit the oil lamp and began drawing on the drawing table that belonged to the original owner's father.

The original owner's father had studied in Germany and was a mechanical engineer. After his father died, his drawing table and drawing tools were all left behind, which came in handy for Li Qinwu.

Li Qinwu is now obsessed with making money to exchange for a clone. Only when he becomes strong can he cope with the coming catastrophe. Designing firearms and getting rewards from the Fengtian Arsenal is his only way to make a lot of money now.

So now the question is, what gun should we copy?

Let’s give up on rifles first. Rifles have become very mature by now, and it’s difficult to make something amazing by taking structural shortcuts. Even if he copies an excellent rifle, it will not attract any attention.

Light machine guns are a good idea. Light machine guns of this era are still in the exploratory stage. For example, the Japanese Type 99 rifle, with its extremely complicated ammunition supply device, is a product of exploration.

As a person of later generations, Li Qinwu naturally knew the answer to the version of the light machine gun: belt-fed ammunition, quickly detachable barrel, and lightweight.

The best at this stuff has to be Russia's PK series. After the end of World War II, Russia's PK series machine guns have always been at the world's advanced level. Simply copying this stuff and making a machine gun that can be fed by a belt with hundreds of rounds of ammunition will surely shock the top management of the arsenal!

Li Qinwu picked up the pen and was about to copy down the structure of the PK series machine gun when he stopped. He remembered what Lao Huotou had said to him before: don't be too ambitious.

With the current level of technology and materials at the Fengtian Arsenal, can it produce a light machine gun of Cold War quality?

There is less than a month left until 918, and Li Qinwu must quickly produce the finished product to profit from the arsenal. The light machine gun is a big thing, and its research and development cycle is too long. It fires full-power bullets, so there are absolutely too many problems. Li Qinwu has no time to correct and debug the weapon!

After hesitating for a long time, he started writing again. This time he was realistic and no longer thought about a big and intimidating thing like a light machine gun. Instead, he designed a submachine gun that fired pistol bullets, was less likely to malfunction, and was more likely to produce results.

He directly chose the famous Bobosha!

He had seen the structure of this gun in movies and TV shows so many times that he could recite it by heart. He also had a great deal of military knowledge and was an excellent student who could solve problems by looking at the answers, so he drew the drawings very quickly.

Li Qinwu chose PPSh for two reasons. One is that PPSh uses a large 71-round drum magazine with an extremely fast firing rate, which can empty the ammunition in 5 seconds.

In this era, automatic weapons had not yet been maturely defined, and submachine guns were often defined as light machine guns.

For example, the warlords in Sichuan produced a batch of Thompson submachine guns, which actually had tripods! This was the result of the user using the submachine gun as a light machine gun.

Therefore, the PPSh-71 with its -round large drum magazine, strong firepower sustainability and fast rate of fire is definitely intimidating enough to attract the attention of the arsenal's top management!

Another reason is that the PPSh is easy to manufacture. Except for the barrel, all other parts of the PPSh are made using the stamping process, which allows for larger tolerances.

The PPSh was designed with large-scale production issues in mind from the beginning, allowing for larger tolerances so that new workers could be used to assemble it and expand production. This was a fatal attraction for the Fengtian Arsenal!

Li Qinwu was drawing the blueprints with great concentration. He would get up and light a new candle only when it went out. After an unknown amount of time, the three views of Bobosha and the data of its 87 parts were all on paper.

Putting down his pen, Li Qinwu yawned, looked outside, and saw that it was actually getting light. He then realized that he had stayed up all night!

With a wry smile, he collected more than 10 drawings on the table and put them in a briefcase. He thought about finding a watch quickly, otherwise he wouldn't even know the time, which would be too inconvenient.

Walking out of the door, Li Qinwu drew water from the well to wash his face. Listening to the crowing of roosters, he picked up the oil paper bag and went to the cellar.

After closing the cellar door, Li Qinwu took out the gun and checked it carefully. He loaded a bullet with 75% gunpowder into it, aimed at a three-finger-thick wooden sign 10 meters away from the cellar, and pulled the trigger.

With a bang, the wooden target was pierced. Li Qinwu rubbed his ears. The 75% charge had a poor silencing effect. It would be difficult to use it to complete the assassination.

But at least the silencer and reduced charge are useful, and the sound of the gunshot is much quieter.

Pull open the bolt, use your fingernail to dig out the shell by scratching the bottom circle of the bullet, put the bullet with 50% charge into the gun, pull the bolt to load the gun, aim at the wooden target and pull the trigger.

There was a "ping" sound, but this time the sound was much smaller, almost as loud as a balloon bursting.

This sound already meets Li Qinwu's needs. With just this sound, when he kills someone and runs away, it should not attract the attention of the guards in the city.

But he still took out the bullet and stuffed the bullet with 25% charge into the chamber.

He pulled the bolt to load the bullet and pulled the trigger. There was a dull thud and Li Qinwu's eyes lit up. The sound was unusually small, almost the same as the sound of pressing the cap of an empty mineral water bottle tightly.

With this sound, I'm afraid that if someone shoots from inside the house, no one outside can hear it. As for the price...

Li Qinwu walked forward, picked up the wooden target and observed it carefully. The last bullet only went in half.

Well, the power is a bit ridiculously low, it can't even penetrate a wooden board three fingers thick, but Li Qinwu thinks that's enough. He will get the muzzle close enough before shooting!
