Live Wilderness Adventure

Chapter 504 Ashes to ashes, dust to dust

Metalworking, an extremely ancient craft whose origins predate even recorded history.

Until thousands of years ago, human beings' knowledge of iron, the most abundant metal 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 of heaven.

Although subsequent civilizations discovered ways to smelt iron and entered the so-called Iron Age, they still did not know how to obtain solid iron that was not easily brittle.

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

Until a great nation discovered steel, they used the hammer in their hands to sway sweat and blood over and over again, and forged enough stable hundred-steel.

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

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

Finally, during the Industrial Revolution, people finally figured out how to get tough, durable, and even cheap iron.

Now, high-quality steel can be seen everywhere, high-rise buildings, cars and ships, railways and trains, bridges and towers, as long as less than two yuan, you can get a pound of iron in the scrap factory.

Black metal completes the transformation from mysterious to ordinary.

Human beings have long since faded away from the mystery of iron and become accustomed to it. The iron and steel industry has become a spectacle in the new era.

Majestic blast furnaces, as high as several floors, operate 24 hours a day, and the temperature can reach thousands of degrees Celsius. In the hot molten iron, no living things and water can remain, requiring the concerted efforts of many engineers.

The entire steel mill devoured ore, coal, and lime like a gigantic insatiable monster.

The products produced by modern steel factories are of high quality and stable 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 history of the development of black metal, even half a century ago, it was still hard-won.

Until this time, a man, a man almost naked, in the most primitive and savage rainforest, used mud and stones from scratch to complete a miracle, which made people think again stand up.

Oh, it turns out that the original iron and steel were trained in this way.

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

He was an adventurer, a nature lover, and a man with madness in his bones.

In front of an audience of more than ten million people, this condensed process of human history was completed.

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

[Ao Jing presented a yacht to the anchor*1—Fang Shen is awesome! Human beings are awesome! 】

[The ashtray will be given as a gift to change the anchor spaceship*100——niu~~~bi~~]

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

【No, it's just sketched out in your own mind, hahahaha】

[Master Mu gave the host a spaceship*10——it can be used as a treasure of the store]

【It's you! Yao Jun, you profiteer! I spent 300 yuan to buy bamboo, but I failed to make a fire once, woo woo woo]

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

[profiteer! Evil businessman! Black merchant! (Ma Chao San Lian)]

What happened to Yao Jun, everyone complains so much?

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

Hot sand distorts the heat.

Undetectable changes occur at the microscopic level, and the grains become finer, denser and tighter, like twisted tendons.

It will be a good knife.

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

It finally worked.

Next, just install the handle, polish it, and it will be a formed dagger.

A steel knife.

A sharp blade with a higher degree of task completion than the iron knife required by the system.

Gradually, the snoring gradually started.

The audience was taken aback, at first they thought it was some strange voice, but after a while they realized it was coming from the microphone, and saw Bi Fang who was facing the sky with his eyes closed.

It was then that everyone remembered that in order to catch up with the progress, Bi Fang hadn't had enough rest for several days in a row, and last night he hadn't slept all night, working on iron all night, coupled with intense physical exertion, he was already exhausted to the extreme, and he was finally able to relax Suddenly, he fell asleep.

[I wipe, is this asleep? 】

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

【Damn, get up quickly】

[Lao Fang get up quickly, 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 fallen asleep.

A moment later, the helicopter flew over, and the electronic sound that hadn't been seen in January sounded again.

[Ding, the main mission three failed, and the degree of completion is low. 】

"Um?"

Bi Fang woke up suddenly, sat up in a daze, and then covered his swollen head.

It hurts.

It seems that magma flows in the narrow cerebral blood vessels, scalds the thin blood vessels, flows into the brain, and finally cracks along the skull along the bone seams, rubs, and turns into coke under 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.

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

"Huh, I'm sorry, I'm too sleepy, I fell asleep as soon as I relaxed."

Bi Fang stood up, took a few deep breaths, and finally bent down and made a motion of touching his toes. After about ten seconds, he stood up. He was obviously much more energetic when he stood up again.

But the fatigue is still there, just not so sleepy.

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

"Before doing it, you can also take deep breaths to temporarily increase the blood oxygen content, which has a miraculous effect. I used to drop my pen 'accidentally' under the table when I was sleepy in class, and then bent down to pick it up for ten seconds."

[I sleep when I am sleepy in class, and Lao Fang picks up a pen when he is sleepy. No wonder I can’t understand anything while watching a live broadcast, and Lao Fang is getting more and more awesome]

【Hahaha, it's too real】

【How to do an office】

"There are also ways to do it in the office. You can straighten your back, raise your feet flat, and tense tightly."

Bi Fang sat on a rock, and the whole movement was like a sit-up, and he paused halfway through. The abdominal muscles were tense, and the serratus anterior on the rib side undulated like a shark's gills.

"Many people will feel sore after ten seconds of persistence. In short, they are quite tired. The principle of this movement 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 inject chicken blood into your body."

Half a minute later, after completing the two sets of movements, Bi Fang was refreshed and full of energy. He came to the blast furnace, moved 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 the sand from? . . 】

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

"Where there is soil, it's not easy to get sand? You just need to understand the principle of soil desertification."

Break up the protective vegetation, dead branches and leaves, crusts, etc. on the soil surface, and the exposed soil will quickly dry out under the action of sunlight and monsoons, and the original aggregate structure will be destroyed, losing the effect of adhesion.

Nutrients such as fine particles will be taken away by wind or precipitation, and non-nutrient coarse particles will remain, forming desertification.

"Things that can be done by natural air drying are faster by man-made. Just remove the dead branches and dead leaves and stones from the soil, keep heating, washing, and reheating, and you can get soil like crushed sand."

Bi Fang poked the dagger with a branch and fished it out.

After shaking off the sand on it, the steel dagger finally showed its full appearance.

But

It's not pretty.

It's not as cold and cold as the audience imagined, and the light can tell people, but it's pitch black, and it can reflect blue light in the sun

Bi Fang didn't care about it, it was just like this when it was processed, and after polishing, it would be shiny.

He took out a polished log, cut it in half evenly, and stamped it on the thin handle of the dagger. After the stamp was made, he grabbed the dagger and cut on the stamp, cutting a groove for each knife to accommodate the thin handle.

The two logs are continuously closed. When the size is suitable and can be stuffed in without being too loose, the collected rubber resin, that is, latex, is applied to it.

"Natural latex has good viscosity after natural air-drying. If possible, it can be vulcanized, so 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 two semicircular logs together, wait for the air to dry and stick firmly, Bi Fang takes out the stone dagger, quickly carves the handle, makes an oval curve, and after making a rough shape, takes out a smooth raw stone to rub, Sand the burrs on the wood smooth and even.

In the last step, wrap the slender rattan evenly around the wooden handle, fix it a second time, put it into the latex, and make the final adhesion.

Vines wrapped around the wooden handle, spit out a black blade, and the tip shone with a little bit of cold light.

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

Bi Fang looked at the shelter and the blast furnace behind him, flashing through the past twenty-one days in his mind, and finally holding the only stone hammer left, he stood under the sun and stared for a long time.

The stone hammer hit the chimney hard, and the cracks spread like spider webs.

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

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

Ashes to dust, dust to dust.
