Live Wilderness Adventure

Metalworking, an extremely ancient craft with origins even predating recorded history.

Until thousands of years ago, human's knowledge of iron, the most abundant metallic element on earth, was almost blank.

Both the ancient Egyptians and the ancient Sumerians believed that iron could only come from meteors, a gift from the gods in heaven.

Although later civilizations discovered a method of smelting iron and entered the so-called Iron Age, they still did not know how to stably obtain iron tools that were strong and not easily brittle.

But iron is too fragile, soft and not sharp, and it is far less useful than copper.

Until a great nation discovered steel, they swayed sweat and blood with their hammers over and over again, and forged steel that was stable enough.

This piece of black metal has finally officially become the protagonist. .

But its production is too expensive and too rare. From mining to ore transportation, to smelting and forging, every iron sword requires countless manpower and material resources.

Finally, in the era of the Industrial Revolution, people finally found out how to get tough, durable, and even cheap iron.

Now, high-quality steel can be found everywhere, tall buildings, cars and ships, railways and trains, bridges and towers, for less than two pieces, you can get a pound of iron in a scrapyard.

Black metal completes the transformation from mysterious to ordinary.

For the mystery of iron, human beings have long since faded away and become accustomed to it, and the iron and steel industry has become a spectacle of the new era.

The majestic blast furnaces, several stories high, run 24 hours a day, and the temperature can reach thousands of degrees Celsius. In the scorching molten iron, no organisms and moisture can remain, which requires the concerted cooperation of many engineers.

The whole steel factory is like an insatiable giant monster, devouring ore, coal and lime.

The products produced by modern steel plants are of high quality and stable quality, enough to be regarded as miracles by the ancients: only with the help of gods, craftsmen can occasionally obtain superb works.

Now, everyone has forgotten that the development history of this ferrous metal, even half a century ago, was still hard-won.

Until this time, a man, a man who was almost naked, in the most primitive and brutal rainforest, used soil, stones, and made something from nothing to complete a miracle, which made people recall again. stand up.

Oh, so the original iron and steel were trained like this.

He smelted iron, turned iron into more stable steel, and finally turned steel into a sharp blade.

He is an adventurer, a nature lover, and a man full of madness in his bones.

In front of an audience of more than 10 million people, this process of condensing the progress of human history has been completed.

At this moment, six million spectators watched, shouted and screamed wildly, and they responded to this moment with the most excited emotions.

[Ao Jing gave the anchor yacht*1 - Fang Shen is awesome! Humans are awesome! 】

[The ashtray presents the anchor spaceship *100—niu~~~bi~~]

[Fuck, when will Langya be able to post pictures? 】

[No, it's just a sketch in your mind, hahahaha]

[The spaceship presented by the Mu Wang to the anchor*10 - can be used as a treasure of the town store]

【It's you! Yao Jun, you profiteer! I spent 300 yuan to buy bamboo, and I didn't succeed in lighting a fire even once, woo woo woo]

[Mr. Yao is a **** genius in some respects. Every time I buy it, I feel like a big injustice, you black-hearted maggot! 】

[Trickster! Bad businessman! Black businessman! (Ma Chao Sanlian)]

Yao Jun, what's wrong with everyone, so much resentment?

Bi Fang looked puzzled, but he believed that Yao Jun would not mess around in the club.

The scalding hot sand distorted the heat.

Imperceptible changes occur at the onlooker level, and the grains become thinner, denser and tighter, like twisted tendons.

It would be a good knife.

Bi Fang collapsed to the ground, closed his eyes and enjoyed the moment.

finally succeeded.

Next, as long as the handle is installed, polished and polished, it is a formed dagger.

A steel knife.

A blade with a higher degree of mission completion than the Iron Knife required by the system.

Gradually, the snoring began to rise.

The audience was stunned for a moment. At first, they thought it was some kind of strange sound. After a while, they realized that it was coming from the microphone. They saw Bi Fang with his eyes closed and his face turned to the sky.

It was only then that everyone remembered that in order to catch up with the progress, Bi Fang had not had enough rest for several days in a row. Last night, he had not slept all night. He had been working on iron all night, coupled with severe physical exertion. Immediately, he fell asleep.

[I wipe, is this asleep? 】

[I can't help but sleep, the helicopter will come in three or four hours]

[Damn it, get up quickly]

......

[Lao Fang is getting up soon, it's past five o'clock]

[It's six o'clock! 】

【Helicopter is coming】

Under the setting sun, the audience kept shouting, but Bi Fang had already entered his dream.

A moment later, the helicopter flew in, and the electronic sound that had not been seen in January sounded again.

[Ding, the third mainline mission failed, and the degree of completion is low. 】

"Um?"

Bi Fang woke up suddenly, sat up blankly, and then covered his swollen head.

It hurts.

It was like magma flowing in the narrow cerebral blood vessels, scalding the thin blood vessels, flowing into the brain, and finally cracking along the skull along the sutures, friction, and turned into coke at high temperature.

Thinking of the nightmare he had just had, Bi Fang forced his eyelids to close, and asked the audience how long he had slept.

[It's just over half an hour, now it's early three o'clock, and it's not even four o'clock. 】

"Huh, I'm sorry, I was so sleepy, I fell asleep after relaxing a little."

Bi Fang stood up, took a few deep breaths, and finally bent down and touched his toes. After about ten seconds, he stood up. When he got up again, he was obviously more energetic.

However, the exhaustion is still there, but it is not so sleepy.

"If you are sleepy and want to wake up quickly, you can try the action I just did. When your head is lowered, the blood will be concentrated to the brain in a short time, allowing the brain to obtain a lot of oxygen and nutrients. , so that the brain becomes active again.”

"Before doing it, you can also take a deep breath to briefly increase the oxygen content of the blood. It works wonders. I used to get sleepy in class, and I would 'accidentally' drop the pen under the table, and then bent down to pick it up for ten seconds."

[I was sleeping when I was sleepy in class, and Lao Fang was picking up a pen when I was sleepy. No wonder now I can't understand anything while watching a live broadcast, and Lao Fang is getting more and more awesome]

[Hahaha, it's too real]

【What do you do in an office?】

"In the office, there are ways too. You can straighten your back, raise your feet flat, and tighten it hard."

Sitting on a rock, Bi Fang paused in the middle of the whole movement like a sit-up, his abdominal muscles were tense, and the serratus anterior on the side of his ribs undulated like shark gills.

"Many people will feel sore after holding for more than ten seconds. In short, they are quite tired. The principle of this action is that when the muscles are active, your sympathetic nerves will be excited, and the 'hypothalamus-pituitary-adrenaline' system will be activated to secrete adrenaline. Take the initiative to give blood to your body."

Half a minute later, after completing the two sets of movements, Bi Fang was refreshed and refreshed. He came to the blast furnace, removed the stones, and stirred the hot sand with branches.

After half an hour of cooling, the hot sand was no longer hot.

[By the way, where did Lao Fang get this sand? . . 】

[Damn it, I also found out, where does the sand come from in the rainforest]

"Where there is soil, it's not easy to want sand? Just understand the principle of soil desertification."

Break up the vegetation, litter, crust, etc. that protect the soil surface, and the exposed soil will dry up quickly under the action of sunlight and monsoon, and the original granule structure will be destroyed, and the effect of adhesion will be lost.

Nutrients such as fine particles will be taken away by wind or precipitation, and coarse particles without nutrients will remain, forming desertification.

"What can be done by natural air-drying is artificially faster. As long as the soil is removed with dead branches, leaves and stones, and the soil is heated, rinsed, and heated again, the soil that is like broken sand can be obtained."

Bi Fang poked with a branch, and after poking the dagger, he fished it out.

Shaking off the sand on it, the steel dagger finally showed its full picture.

But......

Not pretty.

It is not as cold and cold as the audience imagined, and the light can be seen, but it is pitch black, and it can reflect blue light in the sun...

Bi Fang didn't care. It was just like this when it was finished. When it was finished, it would be polished.

He took out a polished log, evenly cut it in half, and then printed it on the thin handle of the dagger. After the mark was made, he grabbed the dagger and cut it on the mark, each cutting a groove that could accommodate the thin handle.

The two logs are constantly closed, and when the size is suitable and can be stuffed in without being too loose, the collected rubber resin, that is, latex, is smeared on it. UU Reading www.uukanshu.com

"Natural latex has a very good viscosity after natural air drying. If conditions permit, it can be vulcanized, and the viscosity will be higher, but I don't have enough time, so I need to install the wooden handle as soon as possible."

Glue the two semi-circular logs together and wait for the air to dry and stick firmly. Bi Fang took out the stone dagger and quickly carved the handle to make an oval curve. After making a rough shape, he took out the smooth rough stone and rubbed it. Sand the burrs on the wood smooth and evenly.

In the last step, the slender rattan is evenly wrapped around the wooden handle, and it is fixed for a second time, and then put into the latex for the final adhesion.

The vines wrapped around the wooden handle, spitting out the black blade six villages, and the tip flashed a little bit of cold light.

Now, all the work is done, and the dagger is completely formed.

Bi Fang looked at the shelter and the blast furnace behind him, and the twenty-one days flashed through his mind. Finally, he held a cautious stone hammer and stood down and stared at it for a long time.

Finally, it hit the chimney, and the fissures spread like a spider web.

The crack gradually spread, turned into a crack, and broke with a bang. The three-meter-high chimney fell to the ground, shaking the earth.

The water monitor lizard trembled slightly, quickly fell down from the tree, got into the cave, and hid in the deepest part.

Dust to dust, dust to dust.
