Rebirth before the doomsday: I quietly emptied the city of supplies

Next, you need to use mud to make a blower shell, and then place the shaft in the middle of the shell. Use thin bamboo to make a handle on one side of the bamboo shaft, and that's it. The last step is to use mud to make a cylinder, about half a meter long.

In this way, a homemade blower is complete. As long as you turn the handle, a steady stream of wind will be ejected from the cylinder. The principle of the blower is the same, that is, the six blades mounted on the shaft rotate to generate wind...

Now I can wait for about an hour. After an hour, the earthen kiln and the homemade blower for smelting iron ore will be almost done. And Ling Qing's hematite will probably be almost done. Then I can officially start smelting iron ore. Of course, I have something to do during this hour. My goal today is to make an axe and a machete!

Well, now I can take advantage of this period of time to make models of these two things. When the time comes, I just need to carve out the shapes of these two tools on a relatively hard surface.

Then pour the molten iron into the mold, and that's it!

Therefore, you must not wait until the iron is melted before making these things. It will be too late by then.

Because I have liked these kinds of knives and swords since I was a kid, I guess all the little boys at that time liked them more! My family was financially tight at the time, so naturally we couldn't afford this kind of toy.

And at that time, there were no such toys, so you could only make them yourself, using sticks or bamboo to carve them yourself, so making these things requires a lot of motivation!

Then Chen Yu started to work. It was enough to use the machete as long as it was handy. There was no need to make it fancy. After all, what he needed now was practicality.

The whole knife is about 0.4 meters long, which should be completely sufficient with the hematite that I have.

...

An hour later, Ling Qing's hematite was almost all smashed into small pieces or crumbs. "Chen Yu, I'm done."

Ling Qing stood up, stretched his body, and said to Chen Yu.

Although this kind of work doesn't consume much physical energy, sitting for a long time will still cause back pain! "Okay, I'll finish it soon..."

Chen Yu responded, and the production of his own machete and axe models was basically completed. Now all he had to do was to build a machete and axe model on the ground!

After Chen Yu made the models of the machete and axe, he started firing the kiln and then smelting the iron ore to extract all the iron elements from the iron ore!

"Go find some firewood now. Make sure it's dry and thick wood." Chen Yu turned and said to Ling Qing.

I have to prepare for the smelting work now, so I can't distract myself to collect firewood. So this task can only be handed over to Ling Qing... "Oh... okay!"

Ling Qing hesitated for a few seconds, and finally nodded, although she felt scared if she were alone.

But as long as I don't stray too far from the shelter, I'm sure nothing will happen! "Well, don't run too far!"

After Chen Yu gave a reminder, he started to light the fire and burn the kiln...

In order to smelt iron ore, the temperature in the earthen kiln must reach more than one thousand degrees, and only then can the iron ore be put in. The firewood I have now should be able to last until then. "Well, I know!"

Ling Qing nodded. Even if Chen Yu didn't remind him, he wouldn't dare to run too far now.

The leopard left an indelible shadow in her heart. If it wasn't for the last resort, she really didn't want to go out alone. After Ling Qing went out, Chen Yu started to burn the kiln. Because he made a blower, it was not too difficult to raise the temperature in the kiln to more than a thousand degrees.

With the help of the blower, Chen Yu soon heated the earth kiln red, definitely over a thousand degrees! Next, Chen Yu put all the crushed hematite ore by Ling Qing into the earth kiln.

But it must be noted that the charcoal in the earthen kiln must reach a height of half a meter, so that all the iron ore can be put in. If there is too little charcoal, the iron ore will penetrate to the bottom of the earthen kiln little by little. In this case, the temperature is not enough and the smelting cannot be successful! "Huhuhuhu..."

Chen Yu kept shaking the handle of the blower, making a whirring sound.

Orange-red flames continuously spewed out from the top of the earthen kiln. Even though Chen Yu was more than half a meter away from the kiln, he could still feel the scorching temperature.

The temperature in the earthen kiln at this moment has definitely exceeded the melting point of iron! "Four Four Seven" "I'm back..."

At this time, Ling Qing walked into the shelter holding a few two or three meter long dry sticks. "Well, with these firewoods, we should be able to refine iron..." Chen Yu nodded and continued to crank the blower.

"There are still a lot of things I picked up just now. I'm going to get them all back now." Ling Qing took a break, drank a sip of water, and set off again.

Anyway, she had picked them up together, and it would be a waste if she didn't take them back! And to smelt so much iron ore, this amount of firewood would definitely not be enough. After saying that, Ling Qing set off again.

Chen Yu directly stuffed a piece of firewood as thick as his arm into the bottom of the earthen kiln, and then accelerated the vibration of the blower. The flames grew bigger and bigger, and the temperature became higher and higher...

After more than four hours, Chen Yu looked from the top of the earthen kiln and could no longer see any small pieces of hematite! If the small pieces had been smelted, then the powdered iron ore must have been smelted successfully. Then Chen Yu stopped shaking the blower, and then found a bamboo pole and turned it over and over in the earthen kiln! As long as the iron element was smelted, they would definitely all be attached together! So this is not difficult to find.

"found it..."

Chen Yu suddenly felt something hard, and then a look of joy appeared on his face. "Did it work?"

Ling Qing on the side also asked excitedly.

"It should be about time. You should step back a little, otherwise you will get burned and it will be troublesome." Chen Yu reminded.

Being burned by iron at over a thousand degrees is no joke. Hearing Jing Mo's words, Ling Qing quickly walked aside!

Chen Yu slowly took out the football-sized iron block from the earthen kiln. "Wow, a pile of iron ore can actually produce so much iron?" Ling Qing asked in disbelief.

She originally thought that if she refined iron from stone, she could at most produce a fist-sized piece of iron! Unexpectedly, it turned out to be such a large piece, which was beyond her imagination... "This is not entirely iron, there is a layer of stone on its surface!"

Looking at the red spot in front of him, Chen Yu spoke.
