Before I even got home, the fragrance was already wafting out.

The cook at home has already prepared a meal and is waiting for them to return.

It's a great feeling.

The iron ore needs to be crushed and then smelted in a crucible, and it takes five or six hours to smelt into water.

After eating, Zhang Yuan also joined the team of tapping iron ore, and the ten utensils had to be completed by himself, and it was not a bad thing to get used to the exercise of his arms in advance.

After a few days of getting along, these shirtless men in winter have an inexplicable sense of trust in Zhang Yuan, which may be caused by the wages they have never seen in their lives, or it may be that Zhang Yuan is from the same place as them.

This kind of trust and closeness is what Zhang Yuan wants to see, he doesn't want someone to report everything he has done to Zhuo Wenjun and Zhuo Wangsun every day.

Looking at the iron ore in the crucible waiting for it to smelt into molten iron, only two or three people were needed, Zhang Yuan arranged for six people to keep watch for every three people in the middle of the night, and he went to the bedroom to rest.

A furnace smelts pig iron, and a furnace smelts wrought iron.

When Zhang Yuan woke up the next day, the first batch of flat pig iron billets had been placed aside.

Because the melting point of pig iron is lower than that of wrought iron, Zhang Yuan wanted to pour molten iron on top of pig iron, so that the transfer of carbon components between them would be more rapid and effective according to normal theory.

The process of carbon osmosis is also the process by which molten iron melts pig iron billets.

And in order to be able to pour many times, the mold of the iron billet is also specially manufactured, almost two yellow clay square sticks with a groove in the middle of the pig iron billet sandwiched in the middle, Zhang Yuan can make people move up and down, or even rotate to adjust.

The preparations were ready, the crucible for smelting the molten iron was already bright, and a pile of sand was poured under the pig iron billet to prevent the dripping molten iron from being wasted, and Zhang Yuan commanded two of the craftsmen to start this crucial process.

"Come, it's not too difficult, let the molten iron be evenly poured on the iron plate, on both sides, several times."

Although everyone didn't know what Zhang Yuan was going to do, they still carried out meticulously according to Zhang Yuan's explanation.

With the echo of sizzling sounds, the pig iron billet in the middle also has a tendency to turn from black to red.

The temperature of the molten iron is too high, and the melting point of the pig iron billet is lower, otherwise this effect will never be achieved.

Seeing that the molten iron in the crucible had gone down halfway, and the pig iron billet had been poured four times, Zhang Yuan felt that he could see if his idea could be realized.

"Stop, almost, put it on top of the sand and wait for it to cool."

"Whoa."

Except for a few craftsmen who had to continue working on the edge of the furnace because they couldn't let the molten iron in the crucible solidify, the rest of them were waiting for the iron billet to cool down, and they were also very curious about what Zhang Yuan's final purpose was.

Seeing that the iron billet was almost cool, Zhang Yuan picked up the iron saw that had been prepared a long time ago, walked to the edge of the iron plate, and ordered the two people to lift it to the anvil and place it, and he wanted to see the iron billet himself.

The steel is silvery-white, wrought iron is close to white, and pig iron is dark gray, and the iron ore smelted here in Linqiong is gray cast iron, and the quality is better than that of white cast iron.

It takes strength to see a tree, not to mention sawing a piece of iron billet, the iron saw in Zhang Yuan's hand is forged from pig iron and is extremely easy to break, in order not to hurt himself, Zhang Yuan sawed it carefully.

The most superficial color is still wrought iron, and once this color changes and is not dark gray, it is steel.

This piece of billet is almost five centimeters thick, while it was originally only two centimeters, and the extra thickness on both sides is made of wrought iron.

"Discolored."

Before he sawed a centimeter down, Zhang Yuan exclaimed, attracting the craftsmen who were already watching to come closer to see.

"Childe, is this steel?"

Zhang Yuan nodded excitedly, which means that at least two centimeters of this iron billet is steel, and the next time Zhang Yuan takes a piece of pig iron billet with a thickness of one centimeter to pour, the effect will be more obvious, and the steel rate will be greatly increased.

"Yes, out of steel, you all take care of your mouths, this steel can make you live the life you want."

The craftsmen knew that Zhang Yuan was not stingy with them, and even if they sold this news to others, such as Zhuo Wangsun and the like, those who were used to looking down on slaves might think that letting these people eat a good meal would be a great reward.

The craftsmen who have monthly money naturally have a much higher vision than before, which is why Zhang Yuan sent them monthly money, and they sent so much at one time, and they couldn't give up their children and couldn't trap the wolf.

Seeing that the steel was produced, Zhang Yuan was in a good mood, and asked several craftsmen to continue to do what he said before, and began to beat the iron billet on top of the anvil.

The steel filling method can only reduce the complicated procedures of the 100 steelmaking process, and there is still a long time, in order to get a real piece of steel, Zhang Yuan still has to hammer it down.

Because of the task of the system, these beats begin to make sense.

The iron billet is too thick, and making an axe should be more labor-saving and time-saving.

Everyone saw Zhang Yuan beating the piece of iron, and they knew what the son in the family was going to do, so no one bothered, the capacity of these furnaces itself was not large, not that they didn't want to make it bigger, but Zhang Yuan felt that the temperature in the smaller furnaces should be higher, although there was no basis for it, but with the concept of excellence, Zhang Yuan still let everyone build these two furnaces.

The molten iron in the furnace was only enough to pour the iron billet once, and Zhang Yuan did not say how much to complete, so everyone had to keep working.

This is the second time Zhang Yuan has built a utensil, and making an axe is far easier and more convenient than making an iron pot, but in order to keep the blade of the axe from being mixed with wrought iron and pig iron, Zhang Yuan can only beat hard to let the two mix together.

As for the quenched liquid, he is not afraid of other people's disgust, anyway, it is just an axe, and Zhang Yuan used his own urine to quench.

It was time-consuming and laborious to find other animals to urinate, and Zhang Yuan did it directly.

The time quickly turned to the morning of the third day, and the axe had actually been completed, but the progress bar of the system task had not beaten, which made Zhang Yuan never stop his work.

Could it be that the back of an axe must also be made of steel?

Just when Zhang Yuan asked himself, the system told him the result.

"How steel is made of steel and iron bones: ten pieces of equipment (one-tenth) are forged from carbon steel smelted by the steel-filling method
