The bronze cone is pierced closer to the bottom of the furnace.

The second senior brother used a lot of force, and directly stabbed a hole in the furnace wall.

After stabbing a hole in the place, he quickly pulled out the awl that had been pierced with a little force in his hand.

The whole process is clean and has some aesthetic touches.

The layman may not know what kind of skill and beauty such an ordinary look has.

But those who have personally engaged in such things can understand what it means for the second senior brother to be like this.

How long does it take to practice to achieve this level?

This is a real skill, and you can't do half a fake.

"......"

As the second senior brother removed the bronze cone in his hand, a stream of red, extremely high temperature liquid flowed out along the hole pierced by the bronze cone.

Seeing this red liquid flowing out, Han Cheng's face couldn't help but turn red.

It was as if the extremely high temperature and red color carried by the red liquid had been transmitted to his face.

He couldn't afford not to be excited.

Because this means that from now on, their own tribe will also be able to smelt iron, officially stepping out of the Iron Age!

Well, to paraphrase the famous quote of the first person to fly to the moon - this is a small step for me, but a giant leap for humanity!

Under Han Cheng's gaze full of excitement, the red liquid that had just flowed down was no longer flowing, but dripping instead.

After a while, even the dripping stopped dripping.

At this time, in the Dao that was shoveled out by the second senior brother on the ground, there were only a few solidified solutions.

Han Cheng couldn't help but sniff.

That's a small step.

This small step is too small, and it has only just been taken, and it has already ended.

If a normal person's step is fifty centimeters away, this step is not even ten centimeters away!

That's too little of a meow!

Han Cheng, who had just become excited, looked at the scene in front of him and kept complaining in his heart.

Of course, it is not particularly surprising that there is such a situation now, because his tribe does not get much iron ore, and it is not bad to be able to get so much melted juice.

Han Cheng said to himself like this in his heart, which can be regarded as a relief for himself.

However, when the second senior brother dug out a hole in the bottom side of the furnace that no longer flowed molten iron, the relief that Han Cheng had just carried out was invalid.

Of course, this is not because after being manipulated by the second senior brother like this, the furnace fell uncontrollably, and then hit Han Cheng.

It's because after the second senior brother took a hole out of one side of the stove, he also got something out of it by the way.

These things are some iron ore that has been placed on it and has not been melted much.

The appearance of these things proves that the reason why there was less molten iron before was not only because of the lack of iron ore, but also because the iron ore was not completely melted.

"Put less charcoal in it, and when you wait until next time, put more charcoal in it."

The second senior brother summarized the situation on the side and came up with a method to improve next time.

Compared with copper and tin, two metals with relatively low melting points, iron has a much higher melting point.

Therefore, even the melting point of iron ore is higher than that of copper and tin ores.

For these things, through Han Cheng's previous narration and in the process of dealing with iron bacteria, the second senior brother knew something.

So when he tried to smelt iron ore in the furnace this time, he also deliberately added more carbon to the furnace.

But now it seems that the charcoal is still a little less.

Han Cheng didn't have anything to say about such a thing.

After all, for a new thing, there is always a process from unfamiliar to familiar.

In this process, it is inevitable that some misunderstandings will occur and some things that are not so good.

If something goes wrong, then correct the mistake and it's all right......

After squatting here and waiting for a while, the solidified molten iron became cold.

Han Cheng reached out and took it into his hand.

In fact, it is not accurate to call it molten iron.

Because there are a lot of impurities in these things that are melted and solidified by iron ore.

Compared with the iron pieces that Han Cheng had seen, or iron products, there was a world of difference in nature.

The lump that Han Cheng held in his hand was extremely bad.

If it is beautiful, it will not be described by Han Cheng as a lump.

The pimples on it are peeling off, and they are not regular at all.

It feels relatively light to pick up.

It is much lighter than the same volume of iron.

When Han Cheng took this extremely unsightly mixture of iron and impurities and looked at it carefully, the second senior brother had already started to use his hands and mud to re-seal the hole that had been carved out in the furnace wall before.

After doing these things, I bring some firewood from the side, put it in the stove, and light it.

This is to dry the newly added wet soil as quickly as possible, and then continue to burn the iron ore that has not been melted.

While the second senior brother was doing this, there were quite a few people on the side, all staring at the mixture of iron and impurities that Han Cheng was holding in his hand.

Many people can't help but keep scratching their heads with their hands.

Because what they saw in front of them was too different from the few tools made of meteorite iron they had seen.

Those who have seen meteoric iron tools in the past really can't figure out what kind of method can be used to turn the iron in its current state into a regular and usable tool.

"Miko, why didn't you catch it with a mold? Isn't it going to have to be melted again? ”

After standing beside Han Cheng and looking at it for a long time, he finally couldn't help but ask the doubts in his heart.

Many of the rest of the people nodded their heads one after another.

This is indeed what puzzles them the most.

Because of the increasing popularity of tribal bronze tools, many people in the tribe have seen how to smelt bronze and how to cast bronze utensils.

They thought that iron was made like bronze, when the iron juice was just flowing out, a mold was placed underneath it, and it was allowed to flow into the mold, and then the tools they wanted to have were cast.

It is not surprising that they, who are ill-informed and have some knowledge of casting bronzes, would have such thoughts.

Because in many cases, people's imagination is based on what they know and come into contact with.

In the case of pure molten iron, there is no problem in casting many utensils by using this method.

Like plowshares.

But what I am doing now is obviously not pure molten iron.

And the number is too small.

Fundamentally, it's simply not enough to cast things.

"Wait a minute, now there are too many of these impurities, and the number is too small......"

Han Cheng said to these people and explained.

As he said this, he began to command some of the people in the colony to have another stove on the side.

This stove is much lower than the one that is being used with wet mud by the second senior brother.

This furnace is not used to smelt steel, but to make iron.

This is also known as the iron-striking stove.

When the second senior brother over there pasted the iron-making furnace, the flames on this side also burned.

Driven by bellows, these charcoals are whirring and burning.

Red.

Seeing this, Han Cheng placed the lump of things he was holding on the stove and let the charcoal fire grill it.

After a while, the lump was completely burned red.

Seeing this, Han Cheng used a pre-prepared bronze pliers to clip it out of the furnace and place it on a prepared bronze ingot.

In the other hand, holding a small hammer, he hammered the lump of things.

I didn't need to exert too much force, because the gap between the lumps was too big at this time.

If you use too much force, it is not easy to hammer them together.

As Han Cheng struck with a hammer, the thing began to deform.

The gaps between them began to shrink, their shapes began to change, and they began to gradually become regular.

And, as he struck, something would fall off the body of the piece and fly to the side.

Someone on the side saw it, and after waiting for a while, when the color of these flying things changed from red to black, he bent down and reached out to pick them up.

My own tribe has only gotten such a little bit of this thing now, and it's a pity that it collapsed.

It's better to pick it up and let Miko continue to beat it.

He picked it up very carefully, and he didn't let go of the slightest bit of crumbs.

Such a move quickly made Han Cheng see it.

In the face of such a careful behavior of the tribesmen, he couldn't laugh or cry, but also felt some emotion in his heart.

"No need to pick it up, these are impurities, not iron.

Only by beating and separating as many impurities as possible can we obtain good iron,"

Han Cheng stopped the man's movements with a smile and gave the reason.

Hearing Han Cheng say this, this person threw away some of the slag he had picked up in his hand, and looked a little embarrassed.

After Han Cheng knocked it for a while, the color of this lump of things was not very red.

Seeing this, Han Cheng stopped beating, picked it up with pliers, and put it back on the iron furnace for incineration.

When the iron is not cauterized, the bellows on the side of the stove are not pushed.

Only when the iron is placed on top and burned will the bellows be pushed.

In this way, not only can the consumption of charcoal be reduced, but also the person who pushes and pulls the bellows can rest without being too tired.

With the push and pull of the bellows, the iron stove, which had been much dimmer not long ago, soon became red again.

It didn't take long for the lump to burn red again.

Seeing this, Han Cheng once again clamped it out with pliers and placed it on the copper ingot to beat it......

Striking iron is something that requires a lot of repetition.

Keep repeating the actions and things you have done before.

In fact, many things in this world need to be repeated repeatedly.

Even human life, many times when you think about it, it feels like it is repeated day after day.

It is in this uninterrupted repetition that so many things have been done.

On the piece of stuff that was beaten by Han Cheng, more and more impurities flew out.

With the collapse and fall off of these impurities, this piece of thing that was beaten by Han Cheng became more and more stylish, and it was much harder than before.

However, the volume of this lump of things has also shrunk severely.

Today, it is a cube with a side length of about two centimeters.

With such a little iron, what is better to use it to make something?

After thinking about it for a while, Han Cheng decided to use it to make a dagger and use it himself.

Something like a dagger may seem of little use in later times, but in this era, it is a very useful thing.

Whether it's used for self-defense, or to cut something, or to dismember some prey for meat, it's inseparable.

Of course, if you want to make a dagger, the iron is not in this state now, and you need to hammer it repeatedly before you can make a dagger with better performance.

Otherwise, it is just a dagger made of pig iron, and its performance is not as good as that of bronze casting.

If this were not the case, iron would not have been called evil gold in the pre-Qin period.

People would rather use bronze than evil gold.

However, if you want to do the following things, you can't use this small hammer, it's too laborious, and it's too inefficient.

So Han Chengcheng put on a sledgehammer and beat him......

Striking iron is not an easy job.

Otherwise, there would be no such thing as striking iron and needing its own hardness.

After beating the iron for most of the day, when he slept at night, Han Cheng slept with a special fragrance.

Not long after lying in bed, I was already asleep.

When I woke up the next morning, I felt pain all over my body.

"Dangdang~"

The sound of the hammering of iron sounded again in the stove.

This time, Han Cheng picked up the small hammer again.

On the one hand, it is because he is tired, and his arm still hurts.

On the other hand, it is because by now, he should also take out the correct posture of the iron-making things he saw in later generations, so as not to make more detours for the people of the tribe.

"When~"

Han Cheng took the small hammer and struck it on the piece of iron, and then quickly withdrew the hammer.

"When~"

After he removed the sledgehammer, a sledgehammer slammed down.

The position where it was beaten was the place where the small hammer that Han Cheng was holding just now was hit.

This person who is holding a sledgehammer to hammer is the second senior brother......
