Chapter 385

After Tong Zhilin's visit, Lu Li immediately sent agricultural experts.

These agricultural experts, together with the tenants of lujiazhuang, farm cattle, and seeds of various crops, came to Zhujing thousand households in tongzhilin to carry out vigorous spring farming.

In addition to farming, the construction of Luli's "industrial zone" also requires manpower. Many people were hired from Tong Zhilin's 1000 households to work and give money and food, which alleviated the food shortage of Zhu Jing's 1000 households.

When commander Liu of Jinshan guard learned about this, he immediately found Lu Li and said: they are all brothers, but we can't favor one over the other!

Lu Li immediately agreed that the spring cultivation and production of Jinshanwei would be carried out by these agricultural experts with a team, and the seeds would also be provided by Lu Li. He also wantonly recruited workers from Jinshanwei. As long as they were willing to come and could work, they would all want money and food.

In this way, Jinshanwei could not help but be happy and grateful to Lu Li.

The progress of penetrating Jinshanwei is much faster than expected.

At the beginning, Lu Li thought that he would wait for Tong Zhilin to cooperate for some time, and others would join him when they saw the benefits. However, he didn't expect that Jinshanwei was so poor that he couldn't wait to come up when he saw the benefits.

That's really Orcs are never slaves unless they are wrapped up in food.

In this way, Lu Li's box of pearls flowed out continuously.

Spending money like water, but the progress of work has increased significantly.

In addition to the manpower for agricultural production, in Luli's industrial zone, brick kilns, coking, mineral processing, ironmaking and blast furnaces, and even workshops everywhere, have got a lot of manpower, and all kinds of infrastructure construction have been accelerating.

Luli didn't take charge of agricultural production. The agricultural experts, with the help of their tenants and Jinshanwei, worked very hard and didn't need Luli's intervention at all.

Lu Li put his main energy on the workshop area.

In order to facilitate the import and export of raw materials, Luli renovated the official road from lujiazhuang to Huating County, and built a port and wharf near the Jing River Bank of Gongfang district.

We have to talk about cement as a building material.

In fact, the Ming Dynasty already had the rudiment of cement, which is called Triassic soil. Its composition is similar to that of cement. It only needs to be mixed and burned.

When Lu Li saw the craftsmen of the Ming Dynasty building roads and concrete, he remembered Cement is also a big killer!

The principle of cement is actually very simple, high school chemistry can be done. Lu Li, who has won numerous college entrance examinations and even studied engineering, has no problem getting a cement kiln out.

As a result, in addition to brick kilns and coal kilns, a cement kiln was built on a hill in lujiazhuang.

Although there is not enough steel to make reinforced concrete, but Using bamboo pole instead of steel bar can also be used, and the effect is good.

The emergence of cement has greatly accelerated the progress of lujiazhuang's infrastructure construction, and even saved money.

After arranging these infrastructure projects, Lu Li plunged into the workshop and began to build guns.

The blast furnace produced the first batch of steel.

After sampling and testing, Luli confirmed that these steels are all qualified medium carbon steel, with higher strength and hardness than low carbon steel, but not as brittle as high carbon steel, which is suitable for gun barrel.

When it comes to gun barrel making, many people's first impression is that Drill!

In fact, it's inefficient and more difficult to process.

The best way to make gun barrel is to make seamless steel tube.

When the blast furnace is opened, the molten steel flows out. When the steel is solidified, a series of rotary extrusion mechanisms are connected behind it, just like kneading dough, which turns the red steel into a steel bar.

After the red steel is rolled into steel bars, a core bar extends from the end of the rotary extrusion mechanism. These red steel bars continue to rotate and extrude, and the core bar runs through the middle of the red steel bar.

Cut off, take down the core, is a complete seamless steel pipe. Put on the next core bar, continue to rub the steel bar, a seamless steel pipe will be produced.

The manufactured seamless steel pipe is cut and polished on the lathe, and the inner hole is cut and polished on the drilling machine. After correction, the rough die of a gun barrel is manufactured.

And then Rifling is also needed.

When it comes to rifling, there are many misunderstandings from the predecessors. They always think that rifling is difficult to process and manufacture. In fact It's simple.

Rifling is not drilled, not chiseled, not carved, but PULL!

Hold the barrel together and pass through the inner hole with something similar to the mandrel used to make seamless steel pipe. In this core, cut a hole, put a knife on it, and pull a rifling out.

Of course, we also need to design a mechanism to ensure that when rifling is pulled, the core bar will rotate slightly, and the pulled rifling is spiral.

For Luli, the processing of barrel and rifling is very easy, but the difficulty is bolt.

The rifle fired by Luli is more than 300 years ahead of the world in today's era. It is similar to the rifle design in the Franco Prussian War.The detonator is ignited, the impact pin is fired, and the paper shell is fixed with ammunition. In addition to not being able to make a metal cartridge case, it is no different from the later single shot rifle shooting method.

Pull the bolt, open the gun, load, lock the bolt, pull the trigger and shoot. In this way, the shooting speed can be used to shoot all over the world. It's no problem to shoot more than ten shots a minute.

Bolt and barrel need high hardness and high strength steel. The main parts that bear the impact of gunpowder explosion are the barrel and bolt.

Fortunately, this is still not a problem. When adding a little manganese ore into the iron making process, the strength, hardness, elasticity and toughness are enough.

Add more manganese ore, high manganese steel is spring steel, and the spring of bolt is solved.

Time went by day. By the end of May, the first batch of 100 rear mounted percussion rifles had been manufactured.

In fact, the output should have been more. The barrel processing is easy. There are more than 2000 barrels in the warehouse. It's just that the processing of bolt and barrel is much more difficult. Even if there are hydraulic machine tools made by Luli, there are not many bolt and barrel.

On this day, Lu Li walked into the warehouse and saw a hundred steel guns in the warehouse, with a bright smile on his face.

With this weapon, which is more than 300 years ahead of the rest of the world, we can hang the whole world.

"Has the quality been tested?"

Lu Li picked up a rifle, stretched out his hand to pull the bolt, polished the fine and bright barrel, and looked at people like a mirror.

"It's been tested. All testing methods and procedures are accepted according to the quality inspection standards you have given. "

Guo Dayuan, the great craftsman in charge of the manufacture of firearms, replied immediately.

Guo Dayuan used to be a blacksmith in Jinshanwei. He used to be responsible for making fireguns, but Jinshanwei is a pot of porridge, and the skill of making guns is not enough.

When he got to Luli, Guo Dayuan was able to show his strong points.

"Passed the quality test?"

Lu Li nodded, "OK, I'll try the gun!"

Carrying a rifle out of the warehouse, Lu Li took a box of paper shells from the ammunition warehouse to load, turned and walked to the shooting range opened up near the mountain forest.

"My Lord, I'm ready to test the target!"

When he came to the range, Guo Dayuan pointed to the target standing on the range and said to Lu Li, "according to your requirements, I have prepared 100 meter target, 200 meter target, 400 meter target and 800 meter target. All the targets are fitted with a 10 mm steel plate. "

During this period of time, Lu Li's unified weights and measures have achieved good results. At least Guo Dayuan, a craftsman of the Ming Dynasty, is full of international units.

"Well done!"

Lu Li nodded, went to the shooting position and put the ammunition on a table of the shooting position.

He didn't start shooting immediately. Lu Li observed the gun first.

This rifle, with a total length of 1.2 meters, a total weight of 10 Jin and a caliber of 10 mm, uses a paper shell to load black powder and fire a 10 mm conical lead bullet. Equipped with the gun is a 40 cm long three edged bayonet.

It looks decent. It's almost the same as the rifles used in the invasion of the later eight countries.

I don't know how powerful it is?

Lu Li opened the bolt, took a paper shell bullet and loaded it into the gun. He pushed the bolt to lock the loading, took his rifle, aimed at the 100 meter target in front of him, and pulled the trigger!

"Bang!"

A plume of gunpowder spewed out from the muzzle of the gun, and the plume rushed two meters away.

Black powder is smoke. There's no way.

After the launch, the recoil force shook the land away slightly, and the bullet came out of the chamber, whistling through the air, pounding heavily on the steel plate of the 100 meter target in front.

Lu Li went up to the 100 meter target with his gun. He saw a hole in the steel plate of the 100 meter target.

One hundred meters pierce ten millimeter steel plate. Its power is frightening! Even if it's an iron can full of plate armour, it can be worn in opposite directions.

Next, Luli tested the 200m, 400m and 800m targets respectively.

The 200 meter target also penetrated the steel plate.

The 400 meter target, the steel plate did not penetrate completely, the bullet stuck on the steel plate.

For the 800 meter target, the steel plate has only one pit, so it can't be penetrated.

But It's scary already!

What's the concept of an effective range of 800 meters?

It is no wonder that when the Allied forces of the eight powers invaded, the 100000 cavalry of senggreeqin charged and were destroyed by platoon guns. Only a dozen of the enemy were killed.

It takes at least one minute for the cavalry to charge 800 meters.

In this one minute time, the breech rifle can be fired about 15 times.

At the beginning, there were 16000 people in the Eight Power Allied forces. Even if only 10000 people lined up to shoot, 150000 bullets could be fired in a minute! It's not a gun yet!

This overwhelming barrage of bullets, hit on the death, wipe on the death, no wonder 100000 cavalry charge was directly smashed.

If this example of cold weapon versus hot weapon does not reflect the power of the firing pin breech gun, let's change it.During the Franco Prussian War, Prussia used a breech gun, while France used a front mounted flint gun. The end is 600000 French troops have been destroyed!

Now, with such a rifle, which has led the world for 300 years, it is enough to crush everything.

"Good! Good! It's a good gun. "

Guo Dayuan, who was next to Lu Li's court, praised him and said, "great craftsman Guo has made great contributions and rewarded 100 liang of silver. The rest of the craftsmen doubled their wages this month. "

"Thank you, my Lord!"

Guo Dayuan was overjoyed. It's very pleasant to work under Lord Lu. If you don't fight or scold, you will get enough money and food, and there will be rewards from time to time. Such a hundred household official is really rare.

"Sir, we have also made samples of the revolver you said."

After thanking him, Guo Dayuan reported another good news to Lu Li.

"Oh? Let's see. "

The revolver was also designed by Luli.

Although the revolver has some disadvantages, such as poor sealing, short range and so on, but It's continuous. This advantage is enough to make people ignore all its disadvantages.

Imagine the enemy rushing to the front of the army in a hail of bullets, ready to take advantage of wantonly cutting and killing. Each soldier takes out a left wheel and "bang bang" several shots in succession, ha ha!

This is to annihilate the enemy on the charging line and give him no chance to get close at all.

A moment later, Guo Dayuan sent a revolver.

Compared with the later revolver, the present revolver is much bigger.

Steel quality and processing technology can not reach the height of later generations, the increase of volume and weight is also impossible.

Lu Li took the revolver gun and weighed about three jin. It's not too heavy. It's about the same weight as the current flint pistol.

The ammunition is still loaded in 10 mm paper case, but the charge is less than that of the rifle, and the size of the bullet is also smaller.

There are only five rounds of ammunition, and the revolver drum is bigger than the later revolver gun.

Put the bullet into the drum, open the hammer, Luli raised his gun and aimed at the 100 meter target in front of him, "bang bang" pulled the trigger and emptied the five methods bullet.

With the method of land separation, only two of the five bullets from the 100 meter target hit the target, and the other three bullets did not know where they had gone.

And when shooting, there was smoke and fire in the gap between the drum and the bullet. I don't know how far it was from the left wheel of later generations.

Readjusting the target, the 50 meter target can hit accurately, the 30 meter target can half penetrate the steel plate, and the 20 meter target can penetrate the steel plate.

The effective killing distance is 50 meters, the armor breaking distance is 30 meters, and the killing distance is 20 meters.

This kind of power, for 1561, has been very good!

"Let the guards have a shooting test for half a month. If there is no problem, they can be finalized for production."

Lu Li looked at Guo Dayuan and said with a smile: "the rifle is named Jiajing 40 rifle. Left wheel It's called a revolver. "

Lu Li also said casually about the finalization and naming of the two guns.

Later in use, the name of Jiajing 40 rifle was widely accepted, but the revolver was given a very "rustic" name, called "five rings".

In this regard, even the land general of Shangzhu state, who later held a high position and was influential all over the world, couldn't resist the broad recognition of the people and couldn't change the name of "earth dregs".

Lu Li can only sigh for this, forget it, just do it! The more soil, the more fighting power!
