Live Wilderness Adventure

"Is this iron?"

"It's iron!"

"It's iron!"

"Damn it, it was successful, it was really successful! Bi Fang has become an iron man!"

In the first venue, the crowd cheered.

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

"Success!"

"Fuck, where did the fireworks come from?"

"Thirty-six dollars a piece, the small shop next door sells it, it is said to be a physical reward..."

[This is a miracle! 】

【iron! ! 】

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

[The temperature is absolutely ridiculously high! 】

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

At the moment when the furnace bridge came out of the land, the camera quickly zoomed in, and only saw the black iron blocks on the furnace bridge being uneven, and many places were still glowing with red light, flickering, like metal breathing.

Holding the stone and smashing it hard, there is almost deformation visible to the naked eye. This is a state that is almost melted...

Amazing.

The audience at home and abroad was amazed.

Before Bi Fang, no one had been able to go deep into the jungle alone like him, refining iron without anything...

too exaggerated. .

In comparison, those who found "wild ore" and brought it to the factory for refining are undoubtedly a piece of shit!

This is not to teach people how to survive in the wild or how to do it. It has reached the point of how to re-establish human civilization by relying on wisdom without the products of modern civilization!

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

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

From catching fish to chicken soup, from single-slope sheds to shelters with walls and roofs, to hoods on rainy days.

All kinds of stone tools, salt, and even now iron.

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

No one doubts that if Bi Fang didn't bring a pair of shorts and a grass skirt when he got off the plane, but a bag of wheat seeds...

Do not!

Maybe he only needs a piece of potato, and he doesn't even need a potato. Give him more time to search, and he may not be able to find a stable source of carbohydrates that can be planted!

【GOD! 】

[God can't condense a piece of iron in the wilderness]

【This is the birth of civilization】

[The messier gave the anchor spaceship*10 - respect civilization! 】

[Fat cat Pete gave the anchor yacht *1 - respect civilization! 】

[Pig Heart and Shrimp Meatballs given to the anchor*66 - Respect to Civilization! 】

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

[What I'm watching is not a live broadcast, but the evolution and process of human civilization]

The audience is even more excited, almost at a loss for words. Anyone who has experienced the process of more than ten days and saw the birth of iron with their own eyes will be like this.

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

Which came first, the thought or the object?

Huaxia did not have tables and chairs before, not because of lack of materials and abilities, but because there was no concept of tables and chairs.

The most valuable thing in this world is not the oil and gold mine, but the human mind.

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 are so excited, of course, I am also very excited."

The beating of his heart made Bi Fang gasp for breath.

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

"I overestimate the production of iron bacteria."

Bi Fang put his hand beside the iron lump. At this time, with the comparison, the audience realized how small the red-glowing iron lump was.

Only the fingernails are big!

Relying on this piece is obviously far from enough, it is far from the requirements of the iron sword.

"At first, I thought ten clay cakes would be enough, but now five are the size of a fingernail, which seems not enough, but there is no need to worry, in addition to the yellow iron bacteria, I also dug up rust soil behind me, and made it out of rust soil. The tortilla iron content is higher, enough to surprise us."

Bi Fang continued to take deep breaths, calming down his excitement.

It is far from over at this moment. After iron is made, iron must be wrought.

"The slime secreted by these iron bacteria is mainly divided into iron hydroxide. I added charcoal as reducing agent C and plant ash as co-solvent. The three were mixed into slime and fired at high temperature in a furnace to successfully make iron. Come."

"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, it is already pure iron. Although there may be a lot of impurities in it, it is no longer comparable to the original powdered iron oxide. "

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

Bi Fang smashed the black lump in front of him with a stone and smashed all the iron pieces out, but he was pleasantly surprised.

The iron lump is not only the one on the surface, but there are two smaller pieces inside, which together make a knuckle as big as a finger joint. In addition to these three pieces, there are also many small iron sands, but they do not add up. How many.

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

"Don't put too much earth cake at a time. Too much may result in twice the result with half the effort, and the reaction cannot be fully burned."

Until the evening, Bi Fang forged a total of twenty clay cakes and obtained an iron ingot slightly larger than his index finger.

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

[Enough? I feel......】

[It should be almost flattened? 】

Bi Fang shook his head: "It's not enough, I can only make a blade like this. What's the use of the blade, do I need to shave?"

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

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

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

The sixteenth day of survival in the Banna Rainforest, there are still five days until the end of the mission.

"Hey!"

As soon as the fish was poured into the puddle, the water monitor lizard habitually ran over and was frightened away by Bi Fang.

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

Last night, I was slapped with a stick, and I muttered in a muffled voice, but today I am a little more honest.

【Does it sound good? Good sound is good head】

【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 earth cake may be made into several pieces, the big one is the size of a knuckle, the next The fingernails are big, no matter how small, they are in bits and pieces, the size of a bean.

Bi Fang gathered all the iron in his hands, almost unable to hold it with one hand.

It is very heavy. In terms of weight, it is almost one kilogram!

Even if the wear and tear is counted, it still weighs one pound, five hundred grams.

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

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

However, there are stones that are harder than iron, such as quartz stone and daffodil, but they are not tough and are easily broken.

With this knock, you have to knock your arm off, right?

When the time comes, let's try again. Bi Fang shook his head, wanting to see if he could melt the iron blocks first, and then directly cast the mold for forging. That would be much simpler, at least easier than direct forging.

There are only five days left, and Bi Fang already has a sense of urgency. Originally, he found the iron bacteria, thinking that there is more than enough time, but he didn't expect that the real big thing is to build knives!

Bringing all the iron, Bi Fang came to the blast furnace again, put the iron blocks into the pottery bowl, sprinkled grass and wood ashes, spread firewood all around to light it, and then kept adding charcoal. The whole process was the same.

At this time, the audience didn't care whether they could practice iron swords or not. They didn't have systematic assignments, and they didn't have Bi Fang's sense of urgency. The moment Fang Shen made iron, they felt that they were already complete.

The white smoke stopped.

Bi Fang lifted the lid of the stove and added the pottery bowl.

Thankfully, the scarlet iron had a tendency to melt, but it was only a trend. The only thing that really started to melt was the iron sand at the bottom of the bowl.

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

"If you want to completely melt the large pieces of iron, the conditions are a little worse now." Bi Fang raised his head and looked at the chimney that was more than two meters long.

The current conditions are not enough, it needs to be further improved!

"The chimney needs to be further increased to three meters, and we have to make a blower. After that, it's almost done."

Throwing the iron into the bowl, Bi Fang did as he said.

Going to the river again, digging clay, washing it, building a chimney, and then making a blower.

The making of the blower is very simple.

"The main components are the inner fan and the outer casing that restricts the airflow."

Bi Fang took two pieces of hard bark. Each piece was twenty centimeters long and five or six centimeters wide. A groove was cut in the middle of each piece, aligned with each other and inserted. A cross-shaped fan blade was completed.

Then he took a thin wooden branch, peeled off the bark, made a cross with a stone dagger, divided it into four small parts, and inserted it into the center of the fan blade.

The two ends of the fan were tied with fiber ropes to ensure that they would not spread out due to material problems. Bi Fang held the long pole and twisted it, and tried it by the campfire. The wind was strong.

The next step is to use clay to make a shell on the outside of the fan blade, and gather the fanned airflow into an air outlet.
