The place where the bronze cone pierced was relatively close to the bottom of the furnace.

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

After making a hole here, he exerted a little force with his hand and quickly pulled out the awl.

The whole process is neat and tidy, yet beautiful.

Outsiders may not know what kind of skills and beauty are contained in such an ordinary-looking thing.

But those who have personally engaged in such things can understand what Second Brother's move means.

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

This is real skill and cannot be faked in the slightest.

“Squeak, squeak, squeak…”

As the second brother moved the bronze cone in his hand away, a red liquid with extremely high temperature flowed out from the hole pierced by the bronze cone.

Seeing the 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 of the red ** were transmitted to his face.

This matter could not allow him not to be excited.

Because this means that from now on, their tribe will be able to smelt iron and officially step into the Iron Age!

Well, to paraphrase the famous words of the first man to fly on the moon - that's one small step for me, one giant leap for mankind!

Under Han Cheng's excited gaze, the little bit of red liquid that had just flowed down stopped flowing and started dripping.

After a while, even the dripping stopped.

At this time, there was only a small amount of solidified solution in the path shoveled out by the second senior brother on the ground.

Han Cheng couldn't help but sniff.

This is indeed a small step.

This step was so small that it was over just as it started.

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

This is so damn short!

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

Of course, the current situation is not particularly surprising, because the tribe does not have much iron ore, and it is quite good to be able to obtain so much melted juice.

Han Cheng said this to himself in his heart, as a way of comforting himself.

However, when the second brother dug a hole on one side of the bottom of the furnace from which molten iron was no longer flowing, Han Cheng's previous solution became ineffective.

This was certainly not because after the second senior brother's operation, the furnace fell uncontrollably and hit Han Cheng.

It was because after the second brother dug a hole in the side of the stove, he also took out some things from it.

These things are just some iron ore that has been placed on top and not really melted.

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

"You didn't put enough charcoal in. Next time, put more charcoal in."

The second brother summarized the situation and came up with ways to improve it next time.

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

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

Second Brother knew something about these things through Han Cheng's previous narration and the process of handling iron bacteria.

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

But now it seems that the amount of charcoal added is still a little too little.

Han Cheng had nothing to say about this matter.

After all, for a new thing, there is always a process from unfamiliarity to familiarity.

In this process, it is inevitable that some misunderstandings will occur and some bad things will happen.

If an error occurs, correct it and it will be fine slowly...

After squatting here and waiting for a while, the molten iron that had solidified together began to cool down.

Han Cheng reached out and took it in his hand.

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

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

Compared with the iron blocks and iron products that Han Cheng saw in later generations, there is a fundamental difference between them.

The lump held in Han Cheng's hand was in extremely bad shape.

If it was beautiful, Han Cheng would not have described it as a lump.

There are a lot of bumps on it, and it's not regular at all.

It feels relatively light to hold.

It is much lighter than an iron block of the same volume.

While Han Cheng was looking at the ugly mixture of iron and impurities carefully, his second senior brother had already started mixing mud to seal the hole that had been opened in the furnace wall.

After doing these things, take some firewood from the side, put it into the stove, and light it.

This is to dry the newly added wet soil as quickly as possible, and then continue to burn the unmelted iron ore.

While the second senior brother was doing this, there were many people around, staring at the mixture of iron and impurities in Han Cheng's hand.

Many people couldn't help but scratch their heads with their hands.

Because what they saw before them was so different from the several tools made of meteorite they had seen before.

People who have seen meteorite tools really can't figure out what method can be used to turn iron in its current state into a regular, usable tool.

"Son of God, why don't you use a mold to catch it? Won't it have to be melted again later?"

Someone stood beside Han Cheng and watched him for a long time, and finally couldn't help but ask the doubts in his heart.

Many other people followed suit and nodded.

This is indeed what confuses them the most.

Because bronze tools in the tribe became more and more popular, many people in the tribe had seen how to smelt bronze and how to cast bronze utensils.

They thought that the making of iron tools was the same as that of bronze. When the molten iron just started to flow out, they would place a mold underneath, let it flow into the mold, and then cast the tool they wanted.

It is not surprising that they would have such thoughts given their limited experience and certain knowledge about bronze casting.

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

If it is pure molten iron, there is certainly no problem in using this method to cast many utensils.

Things like plowshares.

But what we have now is obviously not pure molten iron.

And the number is really too small.

It's simply not enough to cast anything.

"Wait a minute, there are too many impurities and too few in quantity..."

Han Cheng spoke to these people and explained.

As he said this, he began to direct some people in the tribe to light another stove nearby.

This stove is different from the stove that the second brother is building with wet mud. It is much lower.

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

This is the so-called blacksmith's furnace.

By the time the second senior brother had finished pasting the iron-smelting furnace, the flames here also started burning.

Driven by the bellows, the charcoal burns with a whirring sound.

Bright red.

Seeing this, Han Cheng placed the thing in his hand on the stove and let the charcoal fire grill it.

After a while, the thing was completely burned red.

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

With the other hand, he held a small hammer and hit the thing.

I didn't need to use too much force because the gaps between the things were too big.

If you use too much force, it will be difficult to hammer them together.

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

The gaps between them began to get smaller, their shapes began to change, and they gradually became regular.

Moreover, as he knocked, some things would fall off the main body of the thing and fly to the side.

Someone nearby saw it and waited for a while. When the color of the flying objects changed from red to black, he bent down and picked them up.

My tribe has only made this little bit of stuff now. It would be a shame if it collapsed.

It would be better to pick it up and let the Son of God continue to beat it.

He picked up the debris very carefully, not leaving out even the smallest crumbs.

Han Cheng soon noticed this action.

Faced with the tribesmen's thoughtful actions, he felt a little amused and touched at the same time.

“Don’t pick them up, these are impurities, not iron.

Only by beating out as many impurities as possible can we obtain useful iron."

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

After hearing Han Cheng say this, the man threw away the debris he had picked up and looked a little embarrassed.

After Han Cheng knocked it for a while, the color of the thing was no longer red.

Seeing this, Han Cheng stopped hammering, picked it up with pliers, and put it back on the blacksmith furnace to burn it.

When the iron is not being burned, the bellows on the side of the furnace are not being pushed.

Only when the iron block is placed on top and burned will people push the bellows.

In this way, not only can the consumption of charcoal be reduced, but it can also allow the people who push and pull the bellows to have a rest and not be too tired.

With the pushing and pulling of the bellows, the iron furnace, which had seemed much dimmer not long ago, soon became red again.

Not long after, the thing was burned red again.

Seeing this, Han Cheng once again used pliers to pick it out and placed it on the copper ingot to strike it...

Blacksmithing is a job that requires a lot of repetition.

Keep repeating the actions and things you have done before.

In fact, many things in this world require constant repetition.

Even when we think about human life, we often feel that it is a repetition day after day.

It is in this kind of uninterrupted repetition that many things are accomplished.

More and more impurities flew out of the thing that was being beaten by Han Cheng.

As these impurities flew and fell off, the thing being hammered by Han Cheng became more and more stylish, and much harder than before.

However, the volume of this thing has also shrunk significantly.

By now, it has become a cube with a side length of about two centimeters.

With such a small amount of iron, what could I make with it?

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

Something like a dagger may seem useless in later generations, but in this era, it is a very useful thing.

Whether it is used for self-defense, or to carve some things, or to dismember some prey and eat the meat, it is indispensable.

Of course, if you want to make a dagger, the current state of the iron block is not good enough. It needs to be hammered repeatedly before a dagger with better performance can be made.

Otherwise, a dagger made of cast iron would not be as good as one made of bronze.

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 strenuous and the efficiency is too low.

So Han Cheng used a sledgehammer to beat him...

Blacksmithing is not an easy job.

Otherwise, there wouldn't be the saying that a blacksmith must be strong himself.

After hammering iron for most of the day, Han Cheng slept particularly soundly at night.

Not long after lying down on the bed, he fell into a sound sleep.

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

“Dangdangdang~”

The sound of iron being struck in the furnace was heard again.

This time, Han Cheng picked up the hammer again.

This is partly because he is tired and his arm still hurts.

On the other hand, it is because now is the time for him to bring out the correct techniques for making iron tools that he had seen in later generations, so that the people in the tribe will not take detours.

"Dang~"

Han Cheng picked up a small hammer and hit the iron, then quickly took the hammer away.

"Dang~"

After he took away the small hammer, a big hammer smashed down heavily.

The place where the hammer was struck was the same place where Han Cheng had just struck with the small hammer in his hand.

The man holding the sledgehammer and beating the opponent is the second senior brother...
