Da Wei Chun

Chapter 61
Dawei is not deficient in iron, but why is iron armor so expensive?

The reason is very simple: the technology is not enough, although there is a lot of iron, [-]% of them are sponge iron with extremely high impurities.

The impurities here are not charcoal, but sulfur and phosphorus, which can make iron brittle like wood.

Just imagine, if the strength of iron tools such as iron plows and hoes is not enough, you can increase the thickness to make up for them. Anyway, the volume is not very large. Even if the plow body or the hoe body is increased to one inch thick, it will not add much weight.

As long as a little pig iron with very little impurities is used to cross out the plow tip and the hoe blade, it is completely sufficient.

But the Jia Ye is different, let alone an inch, can you try wearing a one-centimeter thick Jia Jia?

Even if you don’t have two hundred catties, you are one hundred and seventy-eight, and you are still fighting, can’t you kill you?
Therefore, if you want the soldiers to wear it, it should not be too thick, but once the thickness decreases, you must find a way to remove impurities and increase the strength of the armor.

In this era, there is no second method except for repeated training and exercise.

According to the blacksmith who had just touched the steel plate, it would take nearly a year even for an experienced blacksmith like him, with two strong assistants, to make a pair of armor leaves... …

And what about Li Chengzhi?
It only took half a day, and it was still fine steel...

Isn't this a miracle?
If it wasn't for Li Chengzhi staring at him, Li Song would have knelt down long ago.

"Really steel?" He breathed excitedly and asked in a trembling voice.

"Being in charge, the little old man dares to guarantee it with his head!" The old blacksmith said decisively.

Relying on this craft to eat most of his life, can he still see it wrong?

"Stainless steel... This is steel..."

Li Songman was full of tears, and trembling slightly, he stretched out his hand to the steel plate that had been quenched by water. His movements were light and gentle, as if he was touching his wife...

Following Li Song's exclamation, the others also woke up and looked at the four steel plates, the ten crucible furnaces, and the pile of iron materials like a hill...

Nearly [-] kilograms of steel can be forged every day?
There are at least [-] sets of zhajia, and if you replace them with steel knives and spear heads, how much is that?
Of all the weapons, the saber, which uses the most iron, only weighs ten pounds!

Isn't this a sign that the Lee family is flourishing?
One was counted as one, all of them were panting heavily, their eyes crimson, looking at Li Chengzhi like a fairy.

See what you're doing?
If I mix explosives and make grenades, will you faint with excitement?
Li Chengzhi snorted and tried again with his hands.

Because of the thorough cooling, the elasticity of the steel plate is better than before. Li Chengzhi estimated that this piece should be high carbon steel.

Not to mention forging armor, it is more than enough for gun barrels.

"Go, stand up!" Li Chengzhi pointed at Li Zhang and then at the steel plate.

"Ah? Oh..." Li Zhang Meng woke up, picked up a steel plate, rushed to a high platform more than ten meters away, and stood on the stone.

The distance is calculated, not far, just five feet.

"Crossbow!" Li Chengzhi stretched out his hand.

Li Bo hurriedly took off the crossbow machine from his back, stepped on the strings with both feet, and loaded Li Chengzhi's arrows.

Li Chengzhi picked up the crossbow, squinted his eyes, and slammed down the hanging knife.

"whoosh"

"when"

There was almost no gap between the two crisp sounds. When the sound reached the ear, the steel plate standing on the stone fell down and fell to the ground.

Li Zhang, who was hiding on the side, ran over quickly, and when he picked up the steel plate, he seemed to be frozen and didn't move.

"Idiot, what are you doing, still not holding me?" Li Song scolded loudly.

Li Zhang was shocked, as if he was awakened by fright, and stumbled back.

"Father...Father...Father..." After shouting three times, Li Zhang finally called his father true.

Li Song almost slapped him angrily.

But when he saw the steel plate in Li Zhang's hand, Li Song's expression suddenly froze, like a sculpture.

The rest of the clansmen noticed the difference, and they all gathered around.

The one-foot-square steel plate is black and bright, and only in the middle, there is a trace that seems to have been scratched by a steel knife a few times.

Most of the people didn't respond, thinking in their hearts: Seeing that the crossbow arrow was shot on it, the steel plate was hit and flew to the ground, how could there not even be a hole the size of a pinhole left?

That's a stone crossbow...

But what about the scratches?

There are also quick responses.

Li Bo asked anxiously, "Where's the arrow?"

"Ah, arrow?" Li Zhang was stunned for a moment, and then replied, "It's rotten... The arrow was crashed, and the shaft was directly chopped..."

"Pick it back!" Li Song growled.

Li Zhang stretched out his long legs, ran to the edge of the high platform, and ran back with a few truncated arrows.

Seeing the things in his hand, other people know why Li Zhang was in a daze just now.

The original three-shuttle-shaped arrow was directly knocked into an iron ball.

As for the arrow shaft made of pine wood, it cracked into several pieces early...

How can it be so hard?
Not to mention Zhajia, even Erlang's Yulin armor is absolutely impossible to collapse the arrow and crack the shaft.

Everyone stared at the steel plate with bulging eyes. Apart from stunned and gasping for breath, they really didn't know how to release the shock in their hearts.

The fins of the fish scale armor are all arc-shaped, and there is space for unloading between the two overlapping fins...

Li Chengzhi didn't have time to explain to them what "spring damping" and "dynamic energy absorption" mean, he just frowned at the arrow.

Li Bo was unlucky and just picked a wrought iron arrow.

But there is no need to try it with arrows. As long as you don't encounter a weapon that cannot be operated by a single person such as a crossbow and a car crossbow, you can only defend against ordinary bows and crossbows.

If it weren't for gun stab protection, he even wanted to make it a millimeter thick.

Li Chengzhi thought for a while, then pointed at Li Zhang and said, "This time you come, use your father's lance, sprint!"

"Hey, good!" Li Zhang answered happily, and picked up a long lance that was more than ten feet long from Li Song's side.

The head of the spear is made of refined steel, and it is two feet long, a bit like a narrow sword, and a bit like a four-shuttle cone.

There are also blades on both sides, in addition to thorns, it can also chop and chop.

In addition to the nearly one-foot-long Sangtuo wooden gun shaft, and the one-foot-long copper gun shaft at the end, the weight is more than 20 catties.

This is Li Song's horse-fighting weapon. It is difficult for ordinary people to carry it, but Li Zhang is playing with guns and flowers as he walks, just like holding a chopstick and playing with power.

It's also mainly because this thing is too expensive, Li Song usually doesn't let him move, but Li Zhang is naturally excited when he hears that he can play.

The gun head and the gun editor are second, there are iron and copper, and it can be made with a little effort. The key is that this gun barrel is really hard to find.

The mulberry spear with a length of one zhang can only come from the trunk of the mulberry tree, and the whole body cannot have knots...

How many silkworms can a mulberry tree so tall raise?
It is not at all what the later generations said about peeling mulberry into pieces and then twisting it with glue or raw lacquer.

People who say this probably don't know what ancient glue and lacquer were made of.

The former uses fish fat or pig skin, which will melt when exposed to the sun for a long time, and such a gun is not as good as a poplar stick.

The latter is tree lacquer. Once it condenses, it becomes brittle like glass. Such a lance without toughness and brittleness, let alone charging on horseback, is stabbing straight under the horse. As long as the enemy's bones are a little harder, it may break the barrel of the gun. ...
