The Emperor's Son-in-Law

The cast iron arrowheads Duan Chun saw were not made of iron alloys. In a violent collision.

Cast iron arrowheads are more likely to break, while copper arrowheads are sharper and stronger.

The second is the huge difference in appearance.

The arrows of the Armory Department are all double-winged flat arrowheads.

The arrowheads made by my father are more complicated with three-edged shapes.

So it is necessary for blacksmiths to shape the arrowheads before they can be used.

The double-winged flat arrowheads of the Armory Department are simpler to make, which is the so-called shoddy work.

They can be put on the arrow shaft as soon as they come out of the mold.

On the battlefield, the hit rate of the double-winged flat arrowheads depends entirely on the archer's skills.

If the archer's hit rate is not high, then this kind of arrow will fly everywhere.

And my father's three-edged arrowheads only require archers to master certain archery skills.

It is not difficult to hit whatever you point to.

However, the copper arrowheads made by my father are too expensive and require extremely high craftsmanship.

Because in ancient times, copper was money!

"Brother Zhao, arrowheads now, in addition to copper and iron."

"Are there no other better materials?"

Duan Chun asked curiously while playing with the arrowhead in his hand.

"Major General, our arrowheads are already the best materials."

"Better than those sent by the Ordnance Department!"

"It can be regarded as the top arrowheads in the world today."

Zhao Changlong replied.

"I know."

"Take me to the smelting workshop and the mold craftsman."

Duan Chun has completely understood the reason in his heart.

Because of the underdeveloped technology, steel arrowheads have not yet been born in this era!

Moreover, the shape of the arrowhead is also problematic.

Although the three-edged arrowhead is more advanced, it is already a very backward design for Duan Chun.

This is also the first time he saw the arrows from the Ordnance Department.

He felt the gap in technology and craftsmanship.

"Major General, you want to go to the smelting and mold workshop?"

"I understand."

The two hurriedly took Duan Chun all the way forward.

Watching the craftsmen carrying steaming, red arrowheads to various blacksmith furnaces.

Duan Chun has made up his mind to help his father improve the craft of arrowheads.

In fact, steel arrowheads are not high-tech. In the ancient Han Dynasty of my country.

Steel arrowheads have already appeared.

Duan Chun remembers very clearly that after the middle of the Western Han Dynasty, the arrowheads on the arrows have been made of steel.

But there are still bronze arrowheads and iron arrowheads.

But in later history, the craft of steel arrowheads was lost!

Successive dynasties still used iron arrowheads and bronze arrowheads.

And only regular armies can use these two types of arrowheads.

Can you believe that the local miscellaneous troops actually use bamboo and wooden arrowheads?

Although Duan Chun can't guarantee whether he can make special high-precision steel in this era.

However, he is absolutely sure to make some steel for making arrowheads.

The technology of making steel has been learned by modern junior high school students.

According to the proportion of carbon input, it is very simple to burn iron into steel alloy.

And my father is still burning money to use copper to make arrowheads.

It is too wasteful, but it is also something my father can't do now.

Since I have seen it, I will help my father save some money and increase the power of arrowheads.

All the way to the back of the blacksmith shop, a burst of high temperature heat hits me.

In front is the workshop for smelting copper slurry.

Looking at the craftsmen who are covering their mouths and noses and holding the flaming arrowheads in and out quickly.

Duan Chun immediately asked Zhang Wu to call a foreman here.

A middle-aged man with a face full of black smoke followed Zhang Wu to Duan Chun.

He immediately knelt on his knees and saluted.

"I, Liu Er, pay my respects to the young general."

Foreman Liu Er is a thin man with a limp.

He is covered with dust and his hair is curled and yellowed by the burn.

Duan Chun quickly reached out and helped Liu Er up.

"Uncle Liu, this is my first visit to the farm."

"Just now I saw the arrowheads being made and felt that there were some issues with the materials used."

"So I came to visit you."

Duan Chun said with a smile.

"Major General, what could be wrong with the arrowheads?"

"Our arrowheads are all made according to the general's requirements."

"We use the best copper blocks and molds."

"In the past, no one dared to stop the flying arrows of the Cavalry Guards on the battlefield."

Liu Er asked in confusion.

"I am not questioning the quality of the arrowheads."

"But the materials used and the shape of the arrowheads need to be improved."

"Uncle Liu, if you don't believe me, can you follow the method I provided?"

"Let's try to make some new arrowheads here today."

"How about letting my father try it himself?"

Duan Chun asked with a smile.

"The major general has an order, how dare I disobey it?"

"I just don't know what kind of arrowheads the major general is going to make?"

Liu Er asked curiously.

"Uncle Liu, it's actually very simple..."

Duan Chun told the foreman his thoughts step by step.

First, the materials, then the molds...

Duan Chun took a stick and drew a picture on the ground, and used his hands and feet to introduce it for nearly ten minutes.

Liu Erben was a craftsman, and he immediately understood Duan Chun's idea.

But he still touched his head and thought about it suspiciously.

"Major General, since you have put forward the idea."

"Then I will let people do what the major general said."

"We already have all the materials here. It's not difficult to make a new mold by boiling a pot of molten iron."

"I'll go and arrange it."

Liu Er nodded and immediately limped away.

After a while, he brought two craftsmen from the workshop on the other side.

The two craftsmen each carried a wooden mold, and after putting it down, they immediately went to fetch a few more buckets of yellow mud.

Making a mold is so simple...

"You make the mold according to what the major general said."

"Major general, I'll boil molten iron according to your method and set it aside."

Liu Er clasped his fists and said.

"Uncle Liu, you must add an appropriate amount of carbon powder according to the formula I proposed."

"Otherwise, it won't meet my requirements."

Duan Chun reminded.

"Yes!"

Liu Er turned and left.

Duan Chun watched the two mold craftsmen pour the yellow mud into the wooden boards.

Then he took a stick and drew a spiral arrowhead he wanted on the ground.

Because Duan Chun knew very well that the arrowheads in ancient times were constantly improving with the times.

The double-winged arrowhead is the arrowhead with the lowest lethality and is most likely to be deflected by armor.

Its only advantage is that it can cause great damage to the throat!

But which longbowman can hit the opponent's throat with every arrow?

And it is after a long distance flight.

The three-edged arrowhead made by my father is just a simple short arrowhead.

This kind of arrowhead can have a certain degree of armor-piercing effect after flying a long distance.

But the effect is not obvious, and it can only cause great damage to the enemy without armor.

Fortunately, in this era, there are not many soldiers who can wear armor.

But the arrowhead that Duan Chun is going to make now is more than twice the length of the three-edged copper arrowhead.

An alloy steel arrowhead with a clear spiral shape!

This is the real armor-piercing arrowhead!
