Live Wilderness Adventure

Chapter 506 Goodbye, Rain Forest.

The wild boar kept sniffing at its feet, and after sniffing for a while, it almost bumped into it. Bi Fang finally came to his senses and dragged the stone away from the spot.

The one in the way walked away, and the wild boar immediately buried its head in the soil, arched its long nose a few times, and offered a nut covered in soil from the soil.

Then a cave was exposed, and a big black rat jumped out of the cave, but it didn't get out of the cave, and was bitten by the wild boar, and ate the bones together.

The audience was shocked. Bi Fang had lived here for more than ten days, but he didn't even notice that there was a mouse hole nearby?

"I almost forgot that wild boars have a better sense of smell than dogs. Many truffle hunters rely on pigs' sense of smell to find them." Bi Fang was delighted.

He has lived here for more than ten days, but he has never discovered that there is a mouse hole under the rock where he often sits.

The water monitor lizard didn't respond either. It's a big fish every day, so it doesn't look down on mice?

[Pigs are so strong that they are useless for military purposes? 】

[Who said no? It’s already there, in the cooking class]

[Cooking class, are you trying to kill me to inherit my property? 】

[Eat and drink enough to have strength, pigs make great contributions. 】

"Because pigs are smarter than dogs, they are more prone to complex emotions, such as fear, withdrawal, and much less obedience. Moreover, pigs have poor eyesight and agility, so they cannot replace dogs. .”

Seeing that their companions had harvested, the other three wild boars huddled together, pouted their curly-tailed buttocks, turned over the entire soil layer, and ate all the little white mice inside that hadn't grown hair yet.

Bi Fang raised his head and said with regret that it was almost time.

"Before I came, a staff member told me that there are a lot of wild monkeys and wild boars in the valley rainforest, but I have traveled so many places, I have seen bison and wild boars, but I have no luck to meet wild monkeys, probably My looks."

This remark amused the audience, who laughed.

The last time slowly fell to the end in the chat, the wild boar had left, the drone was slowly lifted into the sky, and the wind was blowing the forest of 10,000 hectares, which looked like a sea from a distance.

The pale sea.

Treetops form waves, layer upon layer,

Countless homing birds turned into black dots and flew to the distance or between the jungles, only one black dot grew bigger and bigger, bringing a roar.

Everything is like going back to the beginning of the story.

"You say, why do humans need iron?"

Bi Fang suddenly asked.

Of course it's because the iron is easy to use, and the audience's answer was thoughtless.

"Yes, iron is easy to use."

Bi Fang raised the polished and smooth dagger in his hand. The original black appearance had long since disappeared, and the whole body was silvery white, shining bright orange light in the setting sun.

Hard, sharp, full of toughness, who's to say it's not easy to use?

"Bronze is an alloy of copper and tin, and it is also the first widely used metal. Its history can even be traced back to prehistoric times. Iron, which requires high-temperature smelting, developed relatively late, but iron is harder, wear-resistant, and easy to obtain. , so it quickly replaced the status of bronze."

"From architecture, transportation, tools, and weapons, it can be found everywhere. If you want to understand a certain metal and its importance to civilization, then you must look at iron."

"Multiple iron is too soft, even softer than bronze. It can be used in limited fields. When fighting, you definitely don't want your sword to be too soft. At this time, humans need steel."

"Through the centuries, blacksmiths have sought various ways to strengthen wrought iron. They had no guidance from the science of chemistry and could only do so through trial and error.

Eventually they figured out, oh, it turns out that heating wrought iron over charcoal hardens the surface of the wrought iron, making it a good surface for cutting.

So it is speculated that some kind of substance should have entered into the wrought iron to strengthen it. This is the carburizing method.

Gradually, they also discovered a process called 'quenching', as long as the heated iron was immersed in oil or water to cool it quickly, it was harder than the slowly cooled iron.

But it's hard, it's too brittle, if the two touch, it will easily break.

Fumbled and fumbled, they found that this shortcoming could be improved by another technique called 'tempering', which was reheating the iron to a lower temperature and allowing it to cool slowly, allowing the iron to 'relax', The reduced hardness is toughness. "

The rough stone-polished dagger was full of scratches, blurring Bi Fang's cheek.

The roar in the sky was getting closer and closer, and Bi Fang's speech speed was getting faster and faster, and the audience felt reluctant.

The time for parting has come.

"Although the ancients summed up the technology with experience without knowing the principles, every improvement is brought about by thousands of accidents or trial and error, but we are well educated and understand many basic principles, but we can't easily restore these technologies."

"Today, iron and steel smelting has become a complete set of closely connected industries."

"Iron ore and coal mined around the world are transported to large steel mills, ground iron ore is sintered into pellets, and coal is retorted into coke - which is then stacked in layers into blast furnaces up to 100 meters high."

"The treated coke can even be burned at a high temperature of more than 1500°, and the iron ore is directly converted into molten iron, which is then poured into the converter and blown with pure oxygen to oxidize and escape impurities, and add different elements as needed to produce molten steel with precise composition .”

"Finally injected into the mold to cool down, pressed at a temperature of 1100°C to form various shapes, distributed to every field of modern industry, and finally supporting the entire modern civilization."

"How to develop the most accurate formula and manufacture the steel with the best performance is the most hard core contest of modern civilization. Compared with it, I have practiced a small piece of smelting steel in the wilderness, which is not worth mentioning. "

Bi Fang laughed at himself.

The audience panicked immediately.

[How could it be, absolutely awesome! 】

[That is, knowing the whole process, I can only look up]

[I don't care, I don't care, Fang Shen is the best in the world! 】

Bi Fang said: "I know you like me very much, but if you are really interested in ironmaking, then you should study hard. In the future, if you develop more useful materials and contribute to the construction of the motherland, you will already surpass me. "

The helicopter spotted Bi Fang from the dense forest and quickly lowered the rope ladder.

Bi Fang grabbed it and quickly climbed up. Halfway through the climb, he gestured to the driver and straightened up slowly.

"The density of danger in the rainforest is very high. In the 21 days of survival, we have seen many magnificent and dangerous creatures that have never been seen before, from bison to Burmese pythons, from water monitors to cobras, Before I came here, I never imagined that I would meet so many national first and second nationals."

The audience can't help nodding when they think of cobras, giant squirrels, bison, boa constrictors, and the companion water monitor lizard.

"I also built a shelter with Leonardo and made various tools. The most important thing is that I smelted iron and got a steel dagger!"

Bi Fang held high the only harvest that brought out the rainforest.

If they hadn't witnessed it with their own eyes, no one would believe that this knife was forged little by little in the rainforest.

When it came, it was a grass skirt, and when it went, it was still a grass skirt and a steel knife.

"Now, I am leaving. I sincerely hope that the skills and stories I have shown will bring you harvest and happiness."

"So today's live broadcast is over, and we will see you next time!"

【Wow, my god】

【Don't wow】

【Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

[I have a hunch, the next live broadcast will be next time]

The rope fluttered slightly, and Bi Fang was hanging in mid-air, with his back facing the setting sun and covered in gold, he extended his hand to the drone directly in front of him and gave a two-finger salute, and finally lifted off slowly and disappeared.

The screen is completely black.

In the first venue, facing the dimmed big screen, everyone let out a sigh of relief, feeling a little unsatisfied.

In the past 20 days, the shock Bi Fang brought was no less than any previous live broadcast. Although it was not a life-and-death crisis, a steel dagger was enough to make people fall to the ground.

The Fangshen live broadcast room is worthy of its name.

If you don't know where the greatest adventurer of this century is, just turn on the live broadcast, and he will definitely appear.

The helicopter slowly ascended into the wet night sky, and after an unknown period of time, the sky became completely dark.

The city is like a gradually enlarged luminous body, and then the lights of Wanjia in the whole Banna are gradually clear in sight through the wet window.

Farther away, the large expanse of rainforest is particularly black, slowly turning into a pinch of small rainforest, and finally turning into a tree.

The flowing air whirled past the porthole, leaving only a dark sky and distinct layers of gray and white clouds in the field of vision.

"Goodbye, Rainforest."
