I am a primitive

It burned for a while, showing signs of melting and softening.

Seeing that the fire was almost ready, Han Chengcheng used two long wooden sticks to clamp it out of the stove, put it on a stone that had been prepared a long time ago on the side, put out the fire on the two burning sticks, and took Pick up another large wooden stick and start striking while the iron is hot.

"Bang bang bang!"

With his beating, the red slag disappeared in a flash and rolled to the side.

It didn't take long for the group of iron bacteria to turn from red to black.

Han Cheng beat for a while and saw that he couldn't move, so he stopped.

At this time, even half of the previous iron bacteria was gone.

After throwing it into a pottery pot aside and soaking it in water, I picked it up, held it in my hand and looked carefully, and found that this irregular piece was far from the iron.

After thinking for a while, Han Cheng found a stone, smashed the piece of iron that was not even a semi-finished product, and watched carefully for a while, Han Cheng found the figure of the small iron bead inside.

Looking at the eight small iron beads in his hand, the largest of which was no larger than mung beans, Han Cheng couldn't help smiling.

Iron!

This is iron!

It has been four years since I came to this era, and now I finally saw traces of metal, how could Han Cheng not be excited, how could he not be excited?

Hei Wa on the side looked at Han Cheng who was grinning behind his ears, and then at the small bumps in Han Cheng's hands. He really couldn't figure it out. These were just some ugly things. How could Shenzi so happy?

Can this thing make tools that are harder and more durable than stone?

But he soon laughed too, it wasn't that he figured things out, but that he was having fun with Shenzi.

"Burn! Continue to burn!"

Han Cheng cherished the small iron beads in his hand and put them into a clay pot. He yelled excitedly like chicken blood, and put more than a dozen mud bumps into the stove at once...

Starting from this day, the newly built furnace in the Qingque Tribe burned for five consecutive days before finally stopping temporarily.

"Crash..."

"Crash..."

Han Cheng hugged the not too big but heavy jar, shaking it from time to time, with an idiotic smile on his face.

This side is filled with large and small iron beads. This is the result of continuous labor in the past few days, and it weighs about two catties.

This is the scale accumulated after the iron bacteria near the Qingque tribe were scoured.

With these iron beads, he became more confident in the following matters.

With the high-purity iron beads, the next thing to do is to heat and melt these iron beads to make a block of iron.

After much deliberation, Han Chengsi decided to put a layer of charcoal in the stove first, then put the iron beads into four pottery bowls of different sizes and put them on the layer of charcoal.

Then add a thick layer of carbon on top and start to ignite.

This crude method and tool consumes a lot of charcoal and time.

But now is obviously not the time to think about these things. It is already thankful to be able to get the iron out. How can there be any time to consider the loss?

-------------Chapter Dividing Line---------------

After a heavy rain, the weather cleared up, and the whole Qingque tribe seemed a little excited.

There is no rainbow in the sky, but the Son of God has made it himself for many days, and they have been curious about it for a long time, and the lumps of iron have finally been smelted!

It is said that this thing called iron is harder than stone, sharper than the thinnest bone knife, and even the sharpest bone needle cannot be compared with it...

"hiss!"

The witch with staring eyes and a lot of teeth missing, looked at the thing called iron in front of him, and took a sharp breath with his teeth bared.

"hiss!"

The second senior brother who was the leader also stepped forward, and after carefully looking at the things placed on the pottery board in front of him, his face was full of disbelief, and he took a deep breath...

"hiss!"

Shang stepped forward...

They looked at the four things on the stone slab in front of them, and then peeked at Han Cheng, all in a daze.

It turns out that this is iron!

It turns out that iron looks like this!

Can this thing be sharper than a bone knife?Sharper than a bone needle? ...

Everyone was stunned when they saw the four lumpy things placed on the stone slab.

This was highly valued by the Sons of God, and they followed Tie with infinite expectations, completely beyond the imagination of primitive people.

Han Cheng looked at the appearance of the crowd, and then at the four strange-shaped iron bumps on the stone slab, and couldn't help sniffling.

It's no wonder that Wu and Senior Brothers have such expressions, these bumps are really too sorry for the audience.

If Han Cheng didn't know the important role of iron, the reaction would not be better than Wu and the others.

It seems that the finished ironware must be forged quickly, so that these guys can open their eyes.

Feeling ashamed, Han Dashenzi, thinking so, re-ignited the stove and put the largest lump of iron into the stove to burn.

There is another stove next to this stove, and the furnace wall and sealing are better than this stove.

That furnace was built after many experiments in order to melt these tiny iron beads into molten iron.

Compared with copper and aluminum with a lower melting point, it is really not easy to remelt the small iron beads that have been burned into water and get them together.

It can be said that it took a lot of effort.

Han Cheng not only remodeled the stove many times with Hei Wa, but even selected the best charcoal for iron making piece by piece.

Han Cheng tried to add plant ash and carbon powder into these small iron beads again, trying to lower the melting point of the iron beads. After a long time of tossing, these small iron beads were finally melted.

As a liberal arts student who likes history, this is really hard enough.

For these four extremely ugly pieces of iron, Han Cheng has already helped them plan their lives.

The largest piece and the third largest piece are used for knives, and the second largest and smallest pieces are used for chisel and saw.
