"Come in" As soon as Wang Zongwei entered the office, he saluted and said: "Commander, I have a problem here that needs to be solved urgently, but I can't think of a good way, so I want to ask you for advice."
It is well known that Qingcang was reborn and came back through time.
The civilization of his time was definitely much more advanced than it is now, so it was right to ask him some questions.
"Oh, if there is any problem that makes you feel that you can't solve it, let's talk about it."
"It's like this.
The recent batch of iron-made weapons has suffered a lot of wear and tear.
Problems such as rust and breakage are very obvious.
In today's battle, I counted a total of about a hundred weapons with gaps.
Still The captured weapons of the Yellow Turban Army are even worse, and the quality cannot keep up.
Small problems can be solved, but some problems such as gaps will mean that they have to be re-cast, and the products will not be used a few times, which will cause a loss of materials.
It’s big and the labor cost is high.”
The lack of durability of weapons has a lot to do with smelting technology.
Technologies like steel-making were rare in the Eastern Han Dynasty.
"Oh, did you bring samples?"
"Yes, please take a look."
Wang Zongwei took out several large knives and several spear heads and put them on the table.
Qingcang took a look and found that it was as he said.
A big knife had cut a gap and the blade was no longer sharp.
The spear head of a hook and sickle is even more cruel.
The hook and sickle head has been folded back and spread out.
There are two possibilities for this situation.
One is that there are too many impurities in the iron, and the other is that the carbon content is too high, which makes it very brittle and easy to break.
The carbon mentioned here directly determines the quality of ironware.
When the carbon reaches a certain amount, it becomes steel.
Iron is divided into pig iron and wrought iron.
Wrought iron, steel and pig iron are all iron-carbon alloys, distinguished by their carbon content.
Generally, those with a carbon content of less than 0.2 are called wrought iron or pure iron, those with a carbon content of 0.217 are called steel, and those with a carbon content of more than 17 are called pig iron.
Wrought iron is soft, has good plasticity, is easy to deform, has low strength and hardness, and is not widely used; pig iron contains a lot of carbon, is hard and brittle, and has almost no plasticity; steel has the advantages of both pig iron and wrought iron and is widely used by humans.
Most blacksmiths who know this relationship are masters, but in modern times they are just ordinary blacksmiths.
"Commander, if nothing happens, let's study this Shen Nong's Herbal Classic first."
Guan Xiaofeng and others were still in the office, but Qing Cang suddenly forgot about them.
"Okay, thank you for your hard work.
I hope you can study that book thoroughly."
"Then let's go first" The five of them paid a military salute and left.
Qingcang studied these weapons again.
In modern times, these weapons would not be qualified as agricultural tools.
How can such a weapon be used on the battlefield?
If a worker wants to do his job well, he must first sharpen his tools.
Explain how important weapons are.
During the Eastern Han Dynasty, a large number of iron weapons were used, and bronze weapons were rarely used.
In fact, iron weapons already existed as early as the Warring States Period.
Some people may ask why bronze is not used as weapons.
At least it will not rust and looks good.
The disadvantages of bronze are too obvious.
It is much heavier than iron, not hard enough and too brittle.

Why were the weapons of the Bronze Age all swords?
When the weapons of the Iron Age turned into knives, it was because bronze was too brittle and could not be chopped, so it could only be used for stabbing.
And most importantly, iron reserves are incredibly high, which means iron is cheaper and easier to get.
"If that's the case, let's go to the blacksmith's shop.
Maybe there's a solution."
The root of all this lies in the place where these iron tools are produced, so he wants to find the reason there.
He also didn't know how far iron smelting had gone during this period.
"It's the commander.
I'll take you to see it."
Qingcang followed Wang Zongwei with his AK47, rode his black horse, and led dozens of guards to the north of Julu County.
He held a torch and looked around as he hurried on.
It was already night, and it was so quiet here that it made people feel peaceful.
However, the lights in the east were still bright, and the troops were reveling in the carnival.
Compared to there, this place is simply a piece of quiet land.
After walking for another ten minutes, I heard a loud beating sound, disturbing the peace of the night.
There is a separate space here for the blacksmith shop, which is convenient for processing and making weapons at night without disturbing the people.
On the way, Wang Zongwei introduced that there were one hundred blacksmiths in the entire blacksmith shop.
Wang Zongwei got off his horse and stopped the blacksmiths.
"Everyone stop, the commander is here" As soon as these people heard that Qing Cang was coming, they stopped what they were doing and gathered around one after another.
Qing Cang said that there was no need to kneel down in front of him.
Because in modern times, civilians have never been seen kneeling down to worship soldiers.
So these people did not kneel down, but showed expressions of surprise on their cheeks.
Why did this top leader of Julu County come here to inspect today?
The blacksmiths in Qingcang's eyes were naked in this cold weather, wearing only a pair of underpants.
Their muscle lines were very clear, and their shoulders were covered with muscle knots.
The temperature here was extremely high, and everywhere was red-hot.
Iron block.
"Xu Dezhi, come out for a moment."
At this time, a big man walked out from the crowd.
He had dark skin and a face that had seen a lot of time hidden under his disheveled hair.
He is the Xu Dezhi mentioned by Wang Zongwei, the leader here and the captain of the blacksmith shop.
They are employed.
Qingcang pays them to make weapons.
They are like employees of a company, and he is the boss.
In order to facilitate management, a captain is selected from these people.
Xu Dezhi is the captain.
Xu Dezhi replied: "Yes" Qingcang asked: "Your name is Xu Dezhi" Xu Dezhi replied carefully: "Yes, Commander."
Qingcang is very expressive in people's mouths.
When I saw him for the first time today, I was inevitably a little scared.
Because he carries a dangerous aura about him.
Xu Dezhi glanced at the AK47 behind Qingcang, his eyes never leaving for a long time.
Qingcang noticed this, so he took off the gun and handed it to him.
"Xu Dezhi, what do you think this weapon of mine is made of?"
Weapons People look at the AK47 and don't understand at all.
How can this be a weapon?

It has no blade and is not long.
If it hits someone, it may hurt a little, but as a weapon, it is too different.
These are all based on people's understanding of cold weapons.
Compared with the age of guns, their knowledge is still less.
Xu Dezhi carefully took the AK47.
As soon as the gun came into his hand, the muzzle closed directly.
It can be seen that once this gun falls into the hands of other people, they will not be able to use it.
Only then did Qingcang hand him to Xu Dezhi with such confidence.
Xu Dezhi looked at it carefully in his hand, and couldn't put it down.
After a while, he said: "This is made of hundreds of smelted iron."
Xu Dezhi's vision is indeed extraordinary.
Although this AK47 is not entirely made of steel, Xu Dezhi can see the material and can explain why.
It is very likely that he knows similar smelting methods.
Then, as long as you provide guidance and bring new technologies, the problem will be solved
