Live Wilderness Adventure

Chapter 500 Wrought Iron

"Is this iron?"

"It's iron!"

"It's iron!"

"Damn it, it worked, it really worked! Bi Fang has mastered it!"

In the first arena, the crowd cheered.

Someone even exploded fireworks on the spot, and the streamers fell from the sky and fell on everyone's heads.

"Successful!"

"Fuck, where did you get the fireworks?"

"Thirty-six yuan each, sold in the small shop next door, said to be a physical reward"

[This is a miracle! 】

【iron! ! ! ! 】

[With so much charcoal, how many kebabs do you need? 】

[The temperature is absolutely ridiculously high! 】

Bi Fang used a long wooden stick to clamp the iron ingot, but the bottom seemed to be stuck firmly, so he had to take it out together with the furnace bridge as a last resort.

At the moment when the furnace bridge came out of the land, the camera zoomed in quickly, only to see that the black iron block on the furnace bridge was uneven, and many places were still glowing red, flashing and flashing, as if the metal was breathing.

Holding the stone and smashing it hard, there is almost visible deformation with the naked eye, which is almost a melting state.

Amazing.

Audiences at home and abroad were amazed.

Before Bi Fang, no one has ever been able to go deep into the jungle alone and refine iron without anything like him.

too exaggerated.

In contrast, those who find "wild ores" and bring them to factories for refining are undoubtedly a piece of shit!

This is not about teaching people how to survive in the wild or how to use hands-on skills. It has reached the point of how to rely on wisdom to rebuild human civilization without the products of modern civilization!

With the appearance of iron, Bi Fang's live broadcast has completely formed two different levels from the past.

In the past, it could be said to be a simple survival in the wilderness, but now, it is completely different.

From catching fish to chicken soup, from lean-tos to shelters with walls and roofs, to rainy weather with coir raincoats.

All kinds of stone tools, salt, and even the current iron.

All the necessities of life are available, and even higher-end materials have appeared.

No one doubts that when Bi Fang got off the plane, instead of wearing a pair of shorts and a grass skirt, he brought a bag of wheat seeds.

No!

Maybe he only needs a piece of potato, even if he doesn’t need a potato. Give him more time to search, and he may not be unable to find a stable source of carbon water that can be planted!

[GOD! 】

【God can't condense a piece of iron in the wilderness】

【This is the birth of civilization】

[Messier presented the host with a spaceship*10—respect civilization! 】

[Fat Cat Pete presented a yacht to the anchor * 1-respect civilization! 】

[Pig Heart and Shrimp presented to the anchor Meatball*66——Respect Civilization! 】

[I have no money, but! Respect civilization! Give Fangshen a small salute! 】

[What I watch is not a live broadcast, but the evolution and progress of human civilization]

The audience was even more excited, and they almost couldn't choose what to say. Anyone who has experienced the birth of iron after more than ten days will be like this.

A total of six million viewers witnessed this scene, witnessing what is civilization and what is wisdom.

Do ideas come first or things come first?

Huaxia didn't have tables and chairs before, not because they didn't have materials and capabilities, but because they didn't have the concept of tables and chairs.

The most valuable thing in this world is not oil and gold mines, but human thoughts.

Thoughts are more precious than gold and diamonds. They are the most precious wealth of the entire human civilization. Anyone who wants to imprison people's thoughts will definitely suffer backlash in the end.

"You guys are so excited, and of course, I am too."

The heart beat violently, making Bi Fang gasp for breath.

He explained: "But my goal is not only to make iron, remember what I said? To make an iron tool, at least a dagger."

"I somewhat overestimated the production of iron bacteria."

Bi Fang put his hand next to the iron block. At this moment, with the comparison, the audience realized how small the red-glowing iron lump was.

Only the fingernails are big!

Relying on this is obviously far from enough, and it is far from the requirements of Iron Sword.

"At first, I thought ten pieces of soil cakes would be enough, but now five pieces are only the size of a fingernail. It seems that it is not enough, but there is no need to worry. In addition to the yellow iron bacteria, I also dug rust soil behind, and the rust soil made it The soil cake iron content of the soil is higher, which is enough to surprise us."

Bi Fang kept taking deep breaths to calm down his excited mood.

The present is far from over. After iron smelting, iron needs to be forged.

"The slime secreted by these iron bacteria is mainly composed of iron hydroxide. I added charcoal as the reducing agent C, and plant ash as the co-solvent K2CO3. The three were mixed into a mud, which was fired at a high temperature in a furnace to successfully produce Come on."

"Plant ash is decomposed into potassium peroxide and carbon dioxide under high-temperature roasting, which, together with the carbon dioxide produced by combustion, reacts with charcoal to form gas carbon monoxide, and carbon monoxide finally reduces the clay that is already iron oxide to obtain iron."

"If we smelt all the iron, it will be difficult to melt it. At this time, the iron is already a simple substance. Although there may be many impurities in it, it is no longer comparable to the original powdered iron oxide. "

The original plant ash is powder, iron oxide is also powder, blending with each other, the reaction is natural and simple.

Bi Fang hit the black lump in front of him with a stone, and smashed out all the iron pieces inside, which was a bit of a surprise.

The iron lump is not only the one on the surface, but there are two smaller ones inside, which add up to the size of a knuckle. In addition to these three pieces, there are many small iron sands, but the sum is not large. How many.

Bi Fang immediately struck while the iron was hot, put five pieces of clay cakes in again, and continued refining.

"Don't put too much soil cake at one time, too much may get half the result with half the effort and fail to fully burn the reaction."

At night, Bi Fang smelted twenty clay cakes and obtained an iron ingot slightly bigger than his index finger.

He weighed it in his hand, it was very heavy.

[Is that enough? I feel】

[It should be almost flat? 】

Bi Fang shook his head: "It's not enough, what can be produced this way can only be razor blades. What's the use of razor blades? Shall I shave my beard?"

Touching the stubble on his face, Bi Fang was amused by his words.

"What I want is a knife with practical functions, at least it must be a dagger, not to mention that there are many impurities in it, and when it is wrought iron, the volume will be further reduced."

In the next two days, Bi Fang continued to smelt iron, and went out hunting with a bow and arrow halfway, caught a snake and a hare, and salvaged the fish in the fishing ground at the same time.

The sixteenth day of survival in the Banna Rainforest, five days before the end of the mission.

"Hello!"

As soon as the fish was poured into the puddle, the water monitor lizard ran over habitually, but was scared away by Bi Fang's spear.

After living together for a long time, the water monitor lizard became more and more daring. Bi Fang dared to come over to feed while he was still at the water hole. He didn't care or was blind.

Last night, he was beaten severely with a stick, and he made all kinds of dirty things in a muffled voice, and he became a little more honest today.

【Does it sound good? It sounds good】

【Hahaha! 】

When I came to the shelter, there were dozens of large and small iron ingots on the ground at this time. Many times, a piece of soil cake may be smelted into several pieces, the big ones are the size of knuckles, and the smaller ones Fingernails are big, small ones, bits and pieces, some are as big as beans.

Bi Fang gathered all the iron in his hands, and he could barely hold it with one hand.

Very heavy, in terms of weight, almost one kilogram!

Even counting the wear and tear, it weighs one catty, five hundred grams.

The weight of a tactical knife is generally about 400 grams, and that is still including the overall weight of the handle. The one catty in front of him is enough for Bi Fang to forge a dagger.

The only problem is how to forge, he doesn't have a hammer, only a stone hammer

However, there are stones that are harder than iron, such as quartz stone and pea blue stone, but they are hard and not tough, and they are easy to break.

Relying on this knock, you have to break your arm, right?

Let's try again when the time comes, Bi Fang shook his head, wanting to see if he can melt these iron blocks first, and directly cast them for forging, that would be much easier, at least easier than direct forging.

With only the last five days left, Bi Fang already had a sense of urgency. He had found the iron bacteria and thought there would be more than enough time. Unexpectedly, the real big thing was to make knives!

After bringing all the iron with him, Bi Fang went back to the blast furnace, put the iron in a pottery bowl, sprinkled it with plant ash, spread firewood around it and lit it, and then kept adding charcoal. The whole process was the same.

At this time, the audience no longer cares about whether they can practice iron knives. They do not have systematically assigned tasks, nor do they have the sense of urgency of Bi Fang.

The white smoke stopped.

Bi Fang lifted the furnace cover and took out the pottery bowl.

Fortunately, the scarlet iron had a tendency to melt, but it was only a tendency, and only the iron sand at the bottom of the bowl really started to melt.

Hundreds of thousands of grains of iron sand, less than one-third the size of a grain of rice, fused together and stuck to the bottom of the bowl.

"The current conditions are not good enough to completely melt large pieces of iron." Bi Fang raised his head and looked at the two-meter-long chimney.

The current conditions are not enough, to further improve!

"The chimney needs to be further increased to three meters, and we also need to make a blower, so after that, it will be almost the same."

Throw the iron block into the bowl, and Bi Fang will do as he says.

Go to the river again, dig the clay, wash the clay, build the chimney, and then make the blower.

The blower is very simple to make.

"The main components are the internal fan and the external shell that confines the airflow."

Bi Fang took two pieces of hard bark, each 20 centimeters long and 5 or 6 centimeters wide, each with a groove cut in the middle, aligned with each other and inserted, a cross-shaped fan blade was completed.

Then take a thin wooden branch, peel off the bark, cut a cross with a stone dagger, divide it into four small petals, and insert it into the center of the fan blade.

Both ends of the fan are bound with fiber ropes to ensure that they will not be scattered due to material problems. Bi Fang holds the long pole and rubs it. Try it next to the campfire, and the wind is strong.

The next step is to use clay to make a casing on the outside of the fan blades to gather the fanned airflow into an air outlet.
