【Wo Ri ...... It's fucking, it's shaking my mom for a hundred years]

[My mother asked me why I was kneeling to watch the live broadcast]

[Is this GOD?] 】

[So glucose is firewood, and carbon is charcoal, scratching your head? 】

[Dude, don't you understand? Actually, I'm too, shy]

[Yes, glucose sugar is firewood that needs to be boiled, and charcoal is carbon element]

A simple analysis, the audience in the live broadcast room was shocked, and the barrage surged.

What's more, it's a lot of money.

Emperor?

Very rare creatures?

After thanking everyone for their support and rewards, Bi Fang continued to work, piling up the clay and forming a closed kiln little by little.

"There are usually two types of charcoal firing: cellar firing and dry distillation."

"The former uses clay to build a kiln, fill it with wood, and then ignite a fire to burn it, so that the wood is charred in the kiln, and the volatiles escape and the charcoal remains."

"The dry distillation method is to put the wood in a dry distillation kiln and heat and decompose charcoal under the condition of isolated air, which is wood dry distillation."

"The dry distillation method is based on the kiln method, and there are generally two kinds of black charcoal and white charcoal, but we use the cellar firing method here, and the ones produced are all black charcoal."

The clay piles looked like a well, into which Bi Fang poured a large amount of timber and explained:

"Don't build the wood very well, because we need it to burn ourselves, and if we build it tightly, it is likely that charcoal will not be formed inside."

Then he planted wooden strips around the "well" and moved it towards the middle like a tent to form a semi-circular structure, and with the support, he could apply clay to the semi-circle and make a sealed lid, leaving only a small opening at the very top.

Bi Fang raised the torch and lit the wood through the small opening set aside, and when everything began to burn inside, and when the smoke came out, he quickly pasted the last clay on the top to form an isolation environment from the outside world.

At high temperatures, the damp clay quickly dries and changes color, firmly sealing the cellar.

"When the temperature recedes, we can harvest charcoal, and if we have a barbecue in the wild, we can make it with a tin jar and put wood, but we need a larger amount, even if it is a cellar firing method, we may have to do it twice."

Taking advantage of the fact that the wood turned into charcoal, Bi Fang went to the stove he was making again.

After a noon drying and baking, the stove has been completely formed, and the square lid on the side falls on the stove, and even makes a sound like the collision of cement.

"The next thing we're going to do is to make the chimney, the chimney is built at the opening of the center of the circle on this side, the higher the better, but make sure that the speed is not too fast, wait until the next section of the chimney is dry before building the previous section, otherwise we will agree to collapse."

Bi Fang picked up a large frame of cement to his side and pushed clay around the opening.

The whole process is very simple, no different from playing with clay in a kindergarten craft class, like building a castle on the beach.

"Chimneys, everyone should have seen them, there are square and round, but there is a difference, the square is convenient to build, the round pursuit of efficiency, the smoke exhaust is even, and the wind resistance is small, so the chimneys of large factories are generally round, but at home for the convenience of construction, they are usually square."

A square building with a ruler is fine, but a circular shape is far from being that simple, and it requires a lot of things, and a little unevenness may also lead to easy collapse.

"That's why I chose to build a square chimney, and the iron smelted here is far from being efficient."

Bi Fang piled the clay squarely at the smoke exhaust outlet, accumulating little by little to a high place, the speed was not too fast, and the whole was very symmetrical.

Every time a dozen centimeters are made, Bi Fang will use a relatively straight branch to measure it, and only after confirming it will continue to pile up.

Soon, a half-man-high chimney appeared in front of everyone, of course, this height was still not enough.

"Now let's go see if the charcoal is ready."

Bi Fang wiped the clay in his hand, came to the originally closed cellar, and reached out to touch the wall temperature.

Not hot.

"Warm, it should be almost, let's open it and take a look."

The clay after being dried at high temperatures feels like cement, rough and hard, and is not easy to open.

Bi Fang picked up the stone hammer on the side and smashed it the dry and hard cellar, the well-proportioned cellar lid suddenly cracked and collapsed, several pieces of broken soil fell, and a faint white smoke floated up from the gap.

The lumpy, cement-like mud blocks were all broken, and the all-black charcoal appeared in front of everyone.

Bi Fang is not afraid of being hot, he directly stretched out his hand to turn it, and warmed it in his hand, and the wood under it all turned into black charcoal.

[Damn, I heard me right, right? How does it feel like black iron? 】

[Has Fang Shen already practiced iron? Secretly cast a spell? 】

[Awesome, I said a long time ago that Fang Shen is an alien, you still don't believe it]

Bi Fang picked up two long strips of charcoal and blew the white ash on them: "This is black charcoal, commonly known as earth kiln charcoal." Wood ash with a pure black surface or a white powder that can be blown off. At the end of carbonization, the blazing charcoal is formed by cutting off the air in the kiln and extinguishing the fire. ”

"The hardness of black charcoal is small, it can be easily pinched, and it will make a dull sound when struck, and the texture is soft."

Bi Fang took out two pieces of black charcoal and knocked them gently, and suddenly there was a dull metal knocking sound, and everything would shatter if he was forced, which was indeed very magical for many people who had never seen it in a big city.

The product of burning wood actually makes a metallic sound!

He took out all the charcoal in the cellar and put it in the wooden frame, and put a lot of firewood in it.

Exactly the same operation, continue the cap making.

"One cellar of charcoal is theoretically enough, but to be on the safe side, I have to make another one."

After finishing it, Bi Fang returned to the stove and continued to raise the chimney.

By five o'clock in the afternoon, the charcoal was ready and the chimney had been made.

Bi Fang looked at the chimney, which was more than two meters taller than his own people, and was satisfied.

The chimney is square and straight, and the top section is even made of clay steps.

"I'm 1.85 meters tall, and as you can see, the chimney is half as tall as me, almost two meters, which is enough." After pat the dust off his body, Bi Fang came down from the clay steps and went under the stove to start adding firewood.

It didn't take long for white smoke to start rising from the tall chimney.

[Premature life, premature life, polluting the environment! ] 】

[What is this cigarette?,Naturally degraded directly.。。。 】

[It's not as much as a car]

[That's right]

[This chimney is also too high, I feel that ironmaking is promising]

[The progress is so fast]

The audience ridiculed, but they didn't pay much attention to it, compared to the emissions generated by modern industry, Bi Fang's amount of this amount, a few trees were degraded.

Under the sunset, Bi Fang, who was smeared with red clay, was shining with golden light, only wearing a grass skirt and a necklace of animal teeth hanging around his neck, he was wild.

Bi Fang wiped the sweat from his forehead, a little tired.

Today is not a small day, not only has the blast furnace been built, but the charcoal has also piled up a hill, and now my stomach is growling with hunger.

"Tomorrow we can start dealing with iron bacteria, maybe we can start smelting iron in the afternoon, and when I went to pick clay before, I also cut two nice branches, and I am going to make a bow and arrow tonight, and see if I can hunt any pheasants and hares tomorrow, and improve my diet."

Eat fish every day, a lot of thorns, Bi Fang is also tired of eating, tired of eating, especially today at noon was stuck by fish bones, really uncomfortable, fortunately there was no big problem later, but now the throat is still a little sore, there is a foreign body feeling.

In the evening, Bi Fang cooked a pot of vegetable soup with stinky vegetables and fish and enjoyed dinner.

The water monitor lizard, which had been basking in the sun for a day on the dirt slope, also began to come alive, walked quickly to the edge of the puddle, dragged two fish and left, highlighting one of them quickly and accurately.

Bi Fang noticed, but didn't bother to care.

Tired, so be it.

Strange to say, as a cold-blooded animal, the water monitor lizard should not eat so often, perhaps because it is eating and therefore feeling hungry?

Or is it more needed for food during the breeding period?

Animals eat much more simply and rudely than humans, two fish directly tear apart and swallow them, and the well-fed water monitor lizard looks at a big tree, uses its sharp claws to slowly climb up, lying on the branch motionless.

[Anyway, can you see the little water monitor lizard born before the end of the live broadcast?] 】

[Unlikely, didn't the old man say that eggs were laid in June and July? Why don't you have a month or two? When the time comes, Fang Shen will leave early]

[I just checked, good guy, this thing can live to be one hundred and fifty years old]

[Wo Ri? One hundred and fifteen? You're not kidding me? 】

Seeing the audience discussing, Bi Fang thought about it and found that it was really not impossible.

"Spawning in June and July is the norm, but in reality, water monitor lizards have the ability to lay eggs at any time, which is relatively rare in the animal kingdom, especially in areas that lack significant climatic characteristics of the wet and dry seasons, and the spawning of water monitor lizards can take place at any time of the year."

"If this water monitor lizard is special and is not produced in June or July, then we may really encounter the possibility of a baby monitor lizard being born."

Bi Fang's words gave the audience a great surprise.

[Damn, can you really see it?] 】

[Too awesome, right? 】

[How does Lao Fang know everything? 】

Because I've seen the breeding records of water monitor lizards.

Bi Fang complained in his heart.

Every year, the Forestry Bureau releases water monitor lizards, and more than 300 have been released so far.

Although I haven't seen it with my own eyes, I still know a little bit about it.

While the audience was fantasizing, Bi Fang, who was cutting wood and preparing to make bows and arrows, poured another basin of cold water.

"Don't think too much about it, the climate in the dry and wet seasons of Banna Rainforest is distinct, and the possibility of not producing in June and July is not high, and the incubation time of this guy's eggs is uncertain."

"It can range from two and a half months to 10 months or more, and usually six months, and even if it is possible, it can be negligible."

[Ahh

[This guy is so ugly, how can anyone like it? ] Scratching your head】

[Plus one, I feel ugly, this guy is building a nest not far away, I can't count it every day]

[I feel ugly and cute]

【The taste is too heavy! 】

Bi Fang smiled, the stone knife in his hand did not stop, and continued to cut the bow and arrows.

The stone dagger is not convenient after all, if only there was an iron knife.

Looking at the sawdust under his feet, Bi Fang began to imagine the results in a few days.
