Qingcang stood up, pulled a blower directly, and asked others to take several pottery cylinders to the furnace.
At this time, the furnace was filled with red molten iron.
He connected several pottery cylinders together, placed them at the mouth of the furnace and fixed them, aiming them at the red-hot molten iron, and then placed the air outlet of the blower on the other opening of the pottery cylinder.
And said: "The other nine furnaces are made like this."
The others did not dare to neglect and began to move, placing them all at the mouth of the furnace as he requested.
He nodded with satisfaction and said, "My method is called stir-frying steel.
As the name suggests, it stirs the molten iron just like normal stir-frying."
Someone asked: "What's the use of this?"
Someone else said: "Could this help remove impurities so that they can float on the surface?"
Someone else whispered: "I have never seen iron smelted like this.
This is not a child's play."
This man had a beard, probably because he had been exposed to high temperatures for a long time.
The beard was all curly, with no straight beard visible.
Their eyes were full of disdain.
After all, they had all been masters for many years, and they were very disdainful of Qing Cang's behavior.
At this moment, someone reminded him: "Don't be so loud, or you will be caught and beheaded."
The bearded man didn't care.
"What are we afraid of?
We are professionals.
As a commander, he should go to the front line instead of dictating to us here."
"No matter what they say, they will drive the Yellow Turbans out of the county, otherwise our lives would not be so easy and we would still have money."
"That is, if you want to repay a favor, let him fiddle with it a few times.
If it doesn't work out, he will stop interfering.
I have seen such people, and most of them are like this."
Qingcang was not angry after hearing these words.
They were definitely dissatisfied, but the results would definitely surprise them when they came out.
Even Xu Dezhi was like this.
He asked: "Commander, what are you doing?"
"Just follow my instructions.
My method of frying steel can produce as good a material as a hundred smelting iron in a short time."
What they want to know more is why ten blowers are needed together and why ten people are arranged to stand next to the blowers holding hourglasses.
Such a formation made people quite curious as to what kind of medicine Qingcang was selling in his gourd.
The bearded man who originally objected said: "Impossible, that is the legendary Hundred Smelting Iron.
The production cycle is quite long, and the yield rate is pitifully low.
If you want to make it in a short time, it must be a fool's dream."
This caused other people to agree: "No, the things passed down by our ancestors have been passed down through the hard work of generations of blacksmiths, and we have the glory of our blacksmiths today.
Here, we are authoritative and cannot be doubted."
How is it possible within the time?”
But there are still people who support Qingcang.
No, someone said something that directly made some people think it was really possible.
"You can tell by looking at the weapon in his hand.
It's high-quality smelted iron.
If he has this thing, he might be able to make it."
The person who objected went on to say, "It's true that it belongs to him, but that doesn't mean anything.
It doesn't necessarily mean that he can practice it.

I don't believe it anyway."
The process of frying steel is not difficult.
As long as you control the amount of oxygen, you can basically get better iron products.
Although Xu Dezhi didn't believe it, after all, such a big leader was here, so he would do as he said.
After failure, he probably wouldn't interfere with them again.
"Commander, what should we do?"
Qingcang said: "First, ten timekeepers mark the hourglass, and each mark is a certain period of time apart from each other to start timing.
Then the blower hand starts to blow air into the furnace, and the people on the furnace begin to stir the molten iron. , when the sand falls to the mark, the blower hand stops the air supply.
Then the molten iron is taken from the furnace, a blade is forged, and a number is stamped on it, from one to ten. " He kept it as simple as possible and people understood.
This will immediately divide the work and get busy.
The period from blowing to forging is not short.
It is already getting late, so today is probably a day of overtime work.
People are busy and sweaty.
It wasn't until midnight that Xu Dezhi presented the ten forged blades.
Qingcang has never made steel before, so all this is based on memory.
There was no special instrument to measure the carbon content, so he came up with this plan.
Ten furnaces were melted and forged at the same time.
Of course, the pig iron in these furnaces should be from the same batch, otherwise the results would be biased.
Among the ten finished knives, two were selected with similar hardness and toughness.
Again, take out the scales of the two and subdivide them until you get the best one.
If one of the two knives is in the first or tenth position, extend the scale to the morning and evening sides and try again.
As soon as these first batch of blades were delivered, people focused their attention on them.
"Now that the results are out, I want to know if blowing with just a blower will help."
"That's right, without many exercises, how can the iron that comes out be good?"
"Eighty percent of these ten knives are still made of pig iron.
They are just reheated and melted before being shaped.
They must be very weak."
"Look, we'll know the result soon.
We can just go and have a rest."
The bearded man continued: "Let's just watch the show.
I was busy all night in vain doing all these useless things."
People are still full of disbelief, how can a person who knows nothing possibly be able to make steel.
Little did they know that Qing Cang's knowledge reserve was hundreds of times theirs.
He was standing on the shoulders of giants.
If he added the system, he would be invincible.
He knows astronomy from above, geography from below, and knows everything.
These people discussed in low voices, and Qingcang heard them very clearly.
He did not refute, on the contrary, he focused more on the pursuit of results.
"Try these knives one by one to see how hard they are."
Xu Dezhi understood.
He was an old craftsman and had his own way of testing knives all year round.
He picked up a knife numbered one, raised the knife, and slashed at a piece of pig iron.
With a bang, although a hole was cut in the iron, the knife broke into several pieces.
Now people started to make a fuss, but it still didn't work.
The bearded man said coldly: "I'm just saying, if it doesn't work, it won't work.

It's just a waste of time."
"Look again, after all, there are ten more."
The bearded man continued: "If you ask me to guess, these ten will definitely be the same as this one.
Don't look at it.
It's better to go back to bed early."
Qing Cang signaled: "Xu Dezhi, try the tenth one."
If the tenth hand is still as crisp as usual, it really proves that his method is not working, and he has to find a new plan.
If it is soft, it means that his method of frying steel is feasible.
Xu Dezhi picked up the tenth knife, raised it, and slashed it down quickly.
Everyone looked at it, some were disdainful, some were curious, and some didn't even look at it
