showdown!I enjoy life on the island

The essence cores collected from the scorpions have been divided and distributed, except for the two [blood catalyzed] for Black Star and Giant Spirit.

At this moment, they have all turned into ores piled up in the yard.

But the problem is, apart from scorpions, I won't be able to find such a large amount of prey for a while.

Besides, overkill is not a good habit.

There is no special need, it is better for man and nature to live in harmony.

Well, considering the consumption and mining volume, maintaining a stable daily output is actually enough...

The simple review is completed, and the temperature of the ventilated furnace has risen to the expected value.

Lin Xihan went down from the suspended corridor to the vicinity of the workshop, leaning against the door with her arms around her chest, and asked, "What do you want me to do?"

She asked while looking at the inside of the workshop.

Although Xu Le's studio had been completed for a while, the number of times she came in was very few.

Probably the only time I stayed longer was when I was working on parts for compound bows.

The rest of blacksmithing are not her specialties.

In such a highly professional place, the biggest help a layman can do is to watch from a distance and keep out of the way.

Xu Le suddenly called her for help, and she doubted what she could do.

"Bring in a batch of iron ore from outside."

Xu Le didn't raise his head, "The orangutans have been very busy these days, I gave them a big vacation and let them go play in the woods by themselves.

"It's just that you come to fill in the gap."

"So..." Lin Xihan's eyes were burning, "In your eyes, I'm like an orangutan?"

"That can't be."

Xu Le categorically denied, "The orangutans should be stronger and work more efficiently."

Crack, bang, bang... The knuckles on Lin Xihan's fist kept crackling because they were pinched too hard.

"... Forget it, I don't care about you."

She snorted softly, and raised her hand to tie her hair behind her head.

The iron ore outside the workshop had already been blown into pieces when it was collected.

When processing coal mines a few days ago, Xu Le also made a crushing machine, which is now fully utilized.

After being further crushed by a crusher, the iron ore has all become knuckle-sized iron ore particles, which is more convenient to smelt.

Lin Xihan filled a basket with these iron ore grains, brought them into the workshop and handed them to Xu Le.

The ore grains in this basket can weigh tens of kilograms, even if her strength quality exceeds that of ordinary people, the muscles in her arms are tense due to the force.

His face also flushed slightly.

As a result, Xu Le picked up the basket with one hand, and then dumped it into the ventilation furnace.

The flames rose and swallowed the ore grains in an instant.

When he handed the basket back, Lin Xihan tilted her head and wrinkled her nose.

gas!

The strength is amazing...

Under the light of the fire, the muscles on Xu Le's body were sharp and sharp, and the lines were extremely tough.

A layer of perspiration reflects light, almost like a perfect sculpture.

When he first came to the island, he still had fat on his body... Bah, bah, why should I pay attention to his figure!

Xu Le didn't know what Lin Xihan was thinking, he said dryly: "Let's say you are not as strong as the orangutan.

"Xiao Shiliu moved such a basket of iron ore without changing his face or beating his heart."

"Little Sixteen?" Lin Xihan repeated the unfamiliar name.

"Ang..." Xu Le stretched out his hand and said, "One of the orangutans, the one with the round face."

"Then why is it called Little Sixteen?" Lin Xihan was even more confused.

"The moon of fifteen is sixteen round."

So the round face is called Little Sixteen... Lin Xihan drooped her shoulders weakly.

On the other side, in the ventilated furnace ignited by the coal ore, the iron ore particles were quickly melted into molten iron, which leaked downward.

The iron production of the rich ore is close to half. After two furnaces of smelting, dozens of catties of molten iron were collected.

Xu Le poured molten iron into the prepared mold, and hot gas gushed out of the pores of the mold.

Lin Xihan suddenly asked: "I remember that when you cast the red cannon, the mold you used was bigger than the current one?"

The red cannon is only about one meter long, but the mold is usually a circle larger than the casting.

Heavy firearms have a larger margin.

Now the mold is only one meter long, which means that the length of the gun barrel inside may only be about [-] centimeters.

Dozens of catties of molten iron are used to cast a [-]-centimeter cannon body, and the wall thickness of the cannon will not be very thick.

Can the strength reach the standard...

After pouring the pot of molten iron in his hand, Xu Le carefully picked up the sand box and put it on the ground so that all the remaining air bubbles inside could escape.

Lin Xihan's heart trembled when he saw it. The molded sand parts probably weigh more than a hundred catties.

But looking at Xu Le's actions, there is no fireworks at all... It's so easy!

"Yes."

He put the sand box firmly, "After all, this is just a gun barrel, not a complete gun barrel."

Chapter 391 Iron Lined with Copper Wrapped in Copper Hair

Barrage in the live broadcast room——

"Not a complete cannon?"

"This thing can also be cast separately?"

"Cast a section of the gun barrel first, and then cast another section of the gun barrel, huh, long gun barrel!"

"Seriously, Xu Shen won't mess around casually, will he?"

"For firearms, the barrel can be separated from other components, so you don't have to worry about airtightness."

"Cannons are not good. Firearms and ammunition can provide good airtightness. Even if the structure of the fire transmission hole is used, the loss of airtightness is not great."

"But in the case of artillery, the loss of airtightness must be taken seriously."

"Besides, the manufacturing tolerance of the artillery itself is easy to be too large, the machining accuracy is not high, and the chamber will explode when fired!"

"Could it be possible for Xu Shen to make an enlarged version of the Lightning Code?"

"Xu Shen did say that the rear-loading smoothbore gun is coming..."

"Lie down and watch Xu Shen perform!"

"..."

After placing the sandbox for casting the gun barrel properly, Xu Le continued to prepare the next mold.

This mold is much shorter than the first one.

The length is only about thirty centimeters, but the width is about the same.

"Help me get another basket of iron ore grains, fill it up to [-]% full."

"Okay." Lin Xihan replied.

Another basket of iron ore grains was smelted in the ventilated furnace, and the high-heat flames sprayed out from the vent holes and the top of the ventilated furnace.

Lin Xihan was already covered in sweat just leaning against the door of the workshop.

While gently flicking the blouse on her upper body, she watched Xu Le's movements carefully.

It looks so proficient, every movement seems to have been rehearsed many times in advance...

Although Lin Xihan is not a professional, it can be seen from Xu Le's actions.

His whole set of smelting techniques, without years of accumulation, can't do it so smoothly.

He is still so young... Lin Xihan's cheeks were flushed by the firelight.

"Come on, help the sandbox."

While Lin Xihan was in a daze, Xu Le had already smelted the third furnace of iron ore, and was about to inject molten iron into the second mold at this moment.

It is also a simple and smooth movement, pouring molten iron.

Then lightly picked up a sand box of several tens of kilograms, and gently pierce it to shake out the air bubbles.

Set aside to cool and set.

"that's it?"

Lin Xihan noticed that if the shapes inside Xu Le's two molds were put together, they would just be the structure of a complete cannon body.

Just don't know how he's going to put these things together...

"No, not far."

Xu Le wiped off his sweat a little, then shook his head, "This is the iron core, we still need to cast the copper skin."

"Iron core and copper skin?" Lin Xihan felt that this structure seemed familiar.

Barrage in the live broadcast room——

"Iron core and copper skin?!"

"Iron with copper wrapped in copper hair?"

"What the hell? Please use the rare words to mark the pinyin boots."

"Read 'gong', which means cannon."

"Is there really such a structure?"

"Yes, the late Zhu-made artillery is a kind of artillery that we improved and exported with reverse technology after it was introduced from the West."

"It can also be regarded as a variant of the red cannon."

"It's awesome, it looks like this."

"Yes, the red cannon is made of pure iron. It has a heavy body and a slow rate of fire, but its range is amazing and it is powerful enough to break through walls."

"I see, Xu Shen's cannon in red is just like playing with those scorpions."

"Cannons are also made of copper. In fact, the performance is better. There are few or no air holes, it is not easy to explode, and the service life is longer."

"However, the high cost and the fact that copper tends to soften when overheated are also disadvantages."

"The iron core copper skin is a later improved model, the cost is much lower, but the performance is equally awesome!"

"It should be able to withstand greater chamber pressure, which actually means that it is more powerful!"

"So, Xu Shen's wave is to copy this kind of craftsmanship?"

"Difficult. Iron core and copper skin. Xu Shen seems to have to make it into the shape of a Franc cannon. The overall difficulty of the process is soaring."

"The assembly of the iron core and the copper skin requires very high precision. The breech is loaded, and the airtightness will be affected if the breech is not pressed. It is a test!"

"Let's not talk about casting on the island, even the many small workshops outside may not be able to produce iron-core copper-skinned Francois machine guns."

"Can't do it or dare not do it?"

"Haha, haha, there are two factors."

"Actually, it's mainly a matter of craftsmanship."

"Xu Shen dared to do it, which means that there must be no problem with the craftsmanship!"
