Siheyuan: Returning from studying abroad, with extraordinary understanding

There was no point in thinking so much now, so Lin Changqing simply stopped thinking about it.

After the plan was completed, all that remained was to implement it and teach Li Qingyue and the other five students.

After completing this task, Lin Changqing can go home.

Tianjin Port is not far from Beijing. I haven’t been home for more than two years and I don’t know what the situation is at home.

At that time, when he left, his father Lin Fuxing was just a mid-level fitter in a steel factory.

Steel factory? Intermediate fitter?

Lin Changqing suddenly remembered a TV series he had watched in his previous life, "The Beast Courtyard", in which there was a steel plant in Sijiu City, which was the industry of Lou Bancheng.

Doesn't my father work there?

If this is the case, doesn’t that mean that the beast courtyard also exists?

However, he quickly dismissed the idea.

He clearly remembered that the steel plant where his father worked was not called Lou's Steel Plant.

If that were the case, there would be no such thing as a beastly courtyard!

Lin Changqing felt inexplicably relieved at this moment.

He soon came to his senses and wondered what he was afraid of.

Even if there really is a courtyard full of beasts, we shouldn't be afraid!

With his abilities, isn't it easy for him to deal with these beasts?

As long as they don't provoke him, he won't care about these people at all.

Instead of scheming against each other in that small courtyard, it would be better to draw a few more blueprints!

Speaking of the drawings, Lin Changqing immediately thought of the backup plans he had made for studying abroad, which he had not yet completed.

Now that he has storage space and is not worried about losing the drawings, he simply draws them.

The backup plan he was going to prepare was not something mysterious, but the three most famous guerrilla weapons in later generations.

Type 56 automatic rifle, Type 40 rifle, and Type 107 rocket launcher.

Needless to say, the Type 56 automatic rifle is a modified version of the famous AK47 automatic rifle. It has its own advantages and is in line with the national conditions of Dragon Country.

40火，69式火箭筒（全称：1969年式40毫米火箭筒），配用85毫米超口径空心装药破甲弹，是60年代初期在苏制RPG-7型火箭筒基础上改进设计的。

107 rocket launcher, caliber 107 mm, full weight 385 kg in marching state, full weight 613 kg in combat state.

It is 2600 mm long, 1400 mm wide, 1100 mm high, the director is 900 mm long, the total missile weight is 18.8 kg, the initial velocity is 31.4 m/s, the maximum flight speed is 372 m/s, and the maximum range is 8500 m.

The warhead weighs 8.33 kg, the killing radius is 12.5 meters, the firing interval is 0.6 to 0.8 seconds, the elevation range is 0 to 60 degrees, the directional range is 15 degrees to the left and right, and the gun crew consists of 5 people.

Rocket launchers can be fired individually, ignited, or fired with dry batteries.

Easy to carry and powerful.

Lin Changqing thought that the country did not have many copper mines, so there would definitely be a shortage of bullets, and the technology to manufacture copper-clad steel bullets was even more needed.

These three weapons can be said to be very suitable for the current national conditions of Dragon Country.

The manufacturing cost is low, the weapon maintenance technology requirements are low, and the cultural level requirements for the users are low.

Of course, even if the blueprints of these three magical artifacts are drawn, it is still impossible for the Dragon Kingdom to mass-produce them at present.

Even if it is produced, the cost will be quite high.

Lin Changqing thought about it and decided to make some changes.

Also draw the drawings of the Type 56 semi-automatic rifle.

He was quite familiar with these three magical weapons. During his study abroad, he also studied the structure of many guns, so it was not difficult for him to draw the blueprints.

Now that his understanding has improved, it is not difficult for him to make changes.

In order to conform to the country's production situation, he used the three major artifacts as the basis, removed some unnecessary parts, and retained the core.

Combining some components into one larger part makes production easier.

Lin Changqing kept simulating in his mind, and countless ideas burst out.

Time passed little by little. After an unknown amount of time, Lin Changqing finally simulated in his mind three magical tools that were lower cost and easier to manufacture.

These three magical weapons were simple to manufacture, but that was because the Dragon Kingdom had its own industrial base at the time.

We are just starting out now, so the manufacturing cost is much higher.

Now, Lin Changqing has made some modifications, so even a small workshop can produce automatic rifles.

An arsenal with some basic equipment can produce bazookas and rocket launchers.

In this way, the production technology is even more advanced, and if production is carried out at full capacity, the current needs of the country can be met quickly.

Although the three modified artifacts are somewhat inferior in range, accuracy, etc., they are still better than current weapons.

After solving this problem, Lin Changqing finally breathed a sigh of relief.

The blueprint was already in his mind, and as long as he wanted to draw it, he could finish it in one morning.

The production technology of copper-clad steel bullets can also be completed by only slightly modifying some equipment.

The copper plating formula is the key.

However, Lin Changqing also has a solution.

It doesn't take much time.

Lin Changqing thought about it and realized that he had rifles, bazookas, and rocket launchers, but that was still not enough.

His fear of insufficient firepower has kicked in!

We don’t have anti-aircraft weapons yet, but we must have anti-aircraft guns.

Lin Changqing clearly remembered that the bald man was not a human being and sent planes to bomb the country's major cities every day.

I don’t know how many innocent people died.

However, Longguo lacked defense weapons and could only watch the plane fly away arrogantly.

They were killed in the explosion just after the liberation, and had not even had a few days of good life to enjoy. Lin Changqing felt very sad.

In order to prevent tragedy from happening, anti-aircraft weapons are a must.

Thinking about how he had stayed in Tianjin Port since coming back, Lin Changqing felt a little guilty. He thought he was not getting the point!

Only when the national defense strength is improved can the Dragon Kingdom have a stable life.

The improvement of national defense strength depends on military weapons!

I'm actually wasting my time here!

Lin Changqing immediately took the paper and entered his personal little world.

Just slap yourself!

"Snapped!"

"Haven't you read On Contradiction? How come you forgot when you were doing things that you should focus on the main contradiction? Don't you know that you should focus on the key points?"

After cursing himself a few times, Lin Changqing began to draw the blueprint.

He wanted to draw all the drawings immediately.

Including the production technology of copper-clad steel bullets.

Get the information ready and seize the opportunity to hand it over to the country.

The sooner the country gets the information, the sooner it can produce these weapons and the sooner the war can end.

There is a powerful enemy named Eagle Sauce behind us!

Lin Changqing no longer thought about anything else and concentrated on drawing blueprints and writing materials.

Time passed unconsciously.

After drawing the blueprints for the three great weapons and the anti-aircraft gun, I began to write data on the copper-coated steel bullets.

Lin Changqing didn't notice the passage of time. After finishing all this, he was still not satisfied.

He also drew drawings of sniper rifles, pistols, grenades, anti-tank mines, armor-piercing shells, etc.

Thinking that the performance of the three magical weapons he modified was somewhat poor, Lin Changqing combined the memories of his two lives to create a new gunpowder formula.

This gunpowder is simpler to make, but more powerful, making up for the lack of power in artillery.
