Qing Cang stood up, pulled a blower directly, and asked the others to take a few pottery tubes to the furnace. At this time, the furnace was already full of fiery red molten iron.

He connected several pottery tubes together, placed them in the furnace opening and fixed them, aimed at the burned iron, and then placed the blower outlet onto another hole in the pottery tube. He said, "This is how the other nine furnaces are used."

The others did not dare to neglect and began to move, and all placed at the mouth of the furnace as he asked.

He nodded with satisfaction and said, "My method is called stir-frying steel. As the name suggests, it stirs the molten iron just like cooking dishes."

Someone asked, "What's the use of this?"

Someone else said: "Will doing this help remove impurities and allow them to float on the surface?"

Someone whispered: "I have never seen such a smelting iron. This is not a joke!"

The man had a beard on his face, but he might have been staying in the heat often, his beard was curled, and he couldn't see a straight beard.

Their eyes were full of contempt. After all, they were all masters who had been for many years and were very disdainful of Qing Cang's approach.

Then someone reminded him, "Don't be so loud, be careful of being caught and beheaded!"

That beard doesn't care.

"What are we afraid of? We are professionals. As a commander, he should go to the front line, rather than pointing fingers at us here!"

"No matter what, they drove the Yellow Turban out of the county town, otherwise how could our lives be so easy? Is there any money to get?"

"That is, if you want to repay kindness, let him make a few troubles, but he can't make it. He will no longer ask. I have seen such people, and most of them are like this."

Qing Cang was not angry after hearing these words. It was certain that they were not convinced, but they would be surprised when the result came out.

Even Xu Dezhi was the same, and he asked, "Commander, are you?"

"You just do it. My method of stir-frying steel can produce good materials that are no less than 100 iron smelting in a short period of time."

They were more interested in knowing why there were ten blowers together, and why there were ten people who had to stand next to the blower with hourglass. Such a situation made people very curious about what medicine was sold in Qing Cang’s gourd?

It turned out that the objector beard said again: "Impossible, that's the legendary 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 dream!"

This caused others to echo: "No, the things passed down by our ancestors have been passed down by many generations of blacksmiths to achieve the glory of our blacksmiths today. Here, we are authoritative and cannot be suspected! How is it possible in a short period of time?"

But some people still support Qing Cang. Some people said something, which made some people think it was really possible. "You can tell from the weapons in his hand that it is a high-quality iron smelting. He can have this thing, maybe he can really refine it."

The objector continued: "It's his thing, it doesn't mean anything. He may not be able to practice it. I don't believe it anyway!"

The process of stir-frying steel is not very difficult. Just by controlling the intake of good oxygen, you can basically get better iron products.

Although Xu Dezhi didn't believe it, after all, such a big leader here, he would do what he said. After failure, he probably wouldn't interfere with them again.

"Commander, what are we going to do?"

Qing Cang said: "First, ten timers marked the hourglass, and each mark was different for a period of time to start the timing. Then the blower started to send air to the furnace, and the person on the furnace began to stir the molten iron. When the sand fell to the mark, the blower stopped the supply of air. In this way, ten time periods were divided, and the molten iron was taken out from the furnace, a blade was forged, and the number was imprinted, from one to ten."

He tried to make it as simple as possible, and people understood it. The division of labor will be done immediately. The period from blowing to forging is not short. It was originally too late, but today is probably a day of overtime. People are busy all over the place, and they are busy with sweat.

It was not until the second half of the night that Xu Dezhi gave him ten cast blades.

Qing Cang had never refined steel, and all this was based on memory. There was no special instrument for measuring 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 used in the same batch, otherwise the result would be deviated. Among the ten knives in the final product, two of them had hardness and toughness. Then take out the scales of these two furnaces and subdivided until the best one was obtained.

If one of the two knives is on the first or tenth, then extend the scale to both sides of the morning and evening, and do it again.

As soon as these first batch of blades were sent up, people focused their attention on them.

"The result is out! I wonder if it's useful to just blow the blower?"

"That's right, how can the iron that comes out be good without many exercises?"

"Eighty-most of these ten knives are made of pig iron, and they are just reheated and melted before forming a fixed shape. That must be very weak."

"Look at it quickly, we'll know the result in a while, and we can go and rest."

Beard continued, "We'll watch the show! I've been working all night in vain and I'm doing these useless things."

People are still full of disbelief. How could a person who knows nothing be able to make steel? How could they know that Qing Cang has hundreds of times more knowledge than theirs. He is standing on the shoulders of giants. If the system is added, it will be invincible in the world. He knows astronomy and geography, and knows everything.

Qing Cang also heard these people very clearly. He did not refute it. On the contrary, he paid more attention to the pursuit of results.

"Try these knives one by one to see how hard they are?"

Xu Dezhi knew that he was an old craftsman and had his own method for testing knives all year round.

He picked up a knife numbered one, raised the knife, and chopped it down at a piece of pig iron.

With a bang, although the iron was cut out, the knife was broken into several sections. Now the people started to make trouble, but it was still not possible.

Beard said coldly: "I just said it, if it doesn't work, it's just a waste of time."

"Look at it again, after all, there are still ten."

Beard continued, "I guess these ten must be the same as this one. Don't look at it, it's better to go back to bed earlier."

Qing Cang signaled: "Xu Dezhi, do you want to try the tenth hand?"

If the tenth hand is still as crisp as usual, it really proves that his method is not good, and he has to find a new solution. If it is soft, it means that his stir-fried steel is feasible.
