The train driver in the courtyard

in the days that followed.

Li Aiguo drives during the day every day, and when he has free time, he goes to the library of Beijing University to study.

Through the opportunity of studying, I also met several professors.

Of course, it's just acquaintance.

There is no word 'protagonist' written on Li Aiguo's face, and there is no domineering air about him.

The professors only answered his weird questions because he was a diligent and inquiring worker.

The days passed by.

Patience always pays off.

That day, as soon as Li Aiguo returned from driving, he was notified that someone was waiting for him at the gate.

Arriving at the gate of the locomotive depot, Li Aiguo saw an old man wearing a large leather coat standing outside.

This man is a young man with green eyes.

It's just that he doesn't speak Northeastern dialect or English, and he speaks with an authentic Moscow accent.

"Are you Li Aiguo, the driver at the Qianmen locomotive depot?"

"Yes you are?"

"I was entrusted by the professor to give you something."

The old man was very alert. He hid the canvas bag behind his back, looked Li Aiguo up and down, and said, "Can I check your ID?" '

Li Aiguo took out his train driver's ID and handed it over.

Lao Maozi checked it again and touched the steel seal on it with his hand to make sure it was not a forgery. Then he took out a pile of information from his arms.

As soon as Li Aiguo took the information, he turned around and left in a hurry. With that fast pace, he seemed to be avoiding someone, and he was soon lost in the crowd.

Li Aiguo felt that the information in his hand was a little heavy.

night.

All sounds are silent.

In the studio of the Daqianmen Locomotive Depot in Beijing, incandescent light bulbs emit a dim light.

Li Aiguo slowly closed the document and closed his eyes, feeling excited in his heart.

In addition to the original data and technical drawings of the "Iron Fist" anti-tank grenade launcher, this information also contains a large amount of information on some RPG-1 and RPG-2.

The RPG-1 is the first individual recoilless weapon studied by Lao Maozi. It has a launch tube caliber of 30mm, a warhead of 70mm, and no sight or tail. As a result, its performance is very poor and it has not been equipped with any troops.

However, the subsequent RPG-2, 4, 6, and 7 were all improved from the RPG-1.

In particular, the "cone plus cylinder" design is the essence of the RPG family design.

At the end of the information, there is also some handwritten information.

That is a unique nozzle design idea. This nozzle can increase the speed of the recoil gas, allowing the warhead to have greater exit kinetic energy.

As a time traveler, Li Aiguo instantly realized that this thing was the Laval nozzle.

It can be seen that Professor Kirov sent over all the information he could get without violating his principles.

Li Aiguo also knew that these information were not given to him alone, but also to the rabbit who was about to become strong.

Just like what the old experts did when they withdrew.

At that time, evacuation was imminent, and many old experts opened the database and placed those precious technical materials in their offices so that domestic experts could write down how much they were.

This is true comradeship.

It has transcended country restrictions.

Li Aiguo squinted his eyes and looked outside.

The darkness has been dispersed somewhat by the dim lights. Although there is only a few steps away, there is still endless darkness outside, but dawn will always come and the earth will be bathed in light.

I felt in my heart that Professor Kirov was indeed a true warrior.

call.

A charcoal fire rose in the charcoal basin.

The information written in Russian fell into the charcoal pot, and the bright red flames licked it, turning the snow-white paper into ashes bit by bit.

Wisps of gray smoke swirled out of the window.

"Driver Li, is there a fire in the studio?"

The voice of the rescue team member on duty came from next door.

"no!"

Li Aiguo stood up.

The fire in my heart rose.

Open the system panel.

Steam engine driving: 100;

Cooking: 15; Cycling: 95;

Geological exploration technology: 20;

Criminal Investigation Technology: 61;

Mechanical design technology proficiency: 60;

EMU assembly body technology: 30;

Mechanical Skill Mastery: 60:

Hand rub nuke: 0;

Lithography machine manufacturing: 0;

Sow postpartum care: 0;

High-speed rail manufacturing technology: 0;

The current remaining skill points are 326;

326 points!

This unprecedented high score gave Li Aiguo the feeling of being a household worth ten thousand yuan.

Buy and buy!

With excitement, Li Aiguo used trembling hands to search the system for technologies related to RPG design and manufacturing.

RPG-7 manufacturing technology, the entire series requires 2000 points

Is Li Aiguo dumbfounded? No!

We, Li Aiguo, have already prepared.

Because we have a large amount of raw materials for the "Iron Fist" anti-tank grenade launcher, RPG-1, and RPG-2, we only need to purchase a small amount of branch technology.

Just like building a computer, your old computer has memory modules, a motherboard, and a power supply.

So now you only need to spend a little money and buy a Xeon W7-2495X processor to practice typing.

The biggest difference between RPG-7 and its predecessor models is that it has four core technologies.

One is a unique structural design, priced at 100 points.

Its structure includes a launch tube, a sight, a handle, a guard, a strap, sheaths at both ends, a grip, a firing mechanism, a firing mechanism, a safety device and a lever locking mechanism.

The second is the jet ejection principle launch technology. This thing is the world's first rocket launcher that uses the jet ejection principle.

The third one is the unique tail nozzle, because the warhead can achieve greater speed and the effective range is up to 200 meters (against tanks) and 500 meters (against buildings and fixed targets)

And its penetration thickness of rolled homogeneous armor reaches 350 mm to 400 meters.

The penetration thickness of the domestic Type 56 rocket launcher is only 280mm. In the subsequent battles, faced with Lao Maozi's rough-skinned and thick-bodied T-62 tank, he could only do nothing.

The fourth is that the optical sight that combines sighting and measuring has a magnification of 2.7 times and a field of view of 13°. There are 4 horizontal lines on the reticle of the scope, corresponding to the shooting ranges of 100m, 200m, 300m and 400m.

The last thing you need here is a scope.

It's not that Li Aiguo thinks the sight is unimportant.

But he knew very well that even if he created the RPG-7 based on the drawings provided by the system.

However, due to the crude processing technology and lack of a sufficiently strong barrel, only a 'suspected' RPG-7 could be produced.

This thing cannot be done by one person.

His purpose is just to provide those comrades in the military industry with a feasible idea and avoid them taking detours.

I reluctantly spent 300 points and redeemed three technologies.

Li Aiguo closed his eyes, and suddenly some unfamiliar knowledge came to his mind.

After a while, this knowledge melted in my mind like ice cubes and became simple and easy to understand.

Li Aiguo looked through his memories and couldn't help but get excited.

Warlike blood flows in men, and their love for weapons is genetically determined.

Since ancient times, men have been given the mission of hunting and protecting the tribe, and bows, arrows, stones, etc. have become their paraphernalia.

As genes continue from generation to generation to this day, when bows and arrows and stones become guns in hand.

Even the middle-aged men sitting in office buildings in later generations can't resist a real, straight and thick stick.

Li Aiguo now has the opportunity to make an RPG, and he can't wait to find materials.

"Brother Patriot, why don't you sleep?"

Chen Xueru, who was awakened, turned over and saw that Li Aiguo looked a little excited. She suddenly became shy, and a blush spread from her face to her slender and white neck.

Wei Xiaobao has a famous saying: "A woman's face is red, but she misses her husband in her heart."

Li Aiguo put his hands under the quilt and started working.

Chen Xueru opened her mouth both shyly and happily. She rolled her eyes at Li Aiguo first, and then said angrily: "Stop touching, you bad guy, today is not the ovulation period!"

The coquettish look is even more attractive.

At this moment, women often say the opposite. If you really stop, she will feel a sense of loss in her heart.

Chen Xueru didn't even notice it, she was completely immersed in the lingering charm.

Soon the smell in the house became stronger.

The night is getting darker.
