Vacuum coupled with high temperature to isolate oxygen......

Charcoal is then used as a reducing agent......

Xu Le's head looked at the details of the processing process that were transmitted back from the [Material Processing] skill.

It's complicated......

If it weren't for the fact that there was some other mess of skills to build upon, plus I already had a workshop and a stable source of minerals......

Just tossing such a near-vacuum iron pipe out, it is not an easy task.

Not to mention the refining of phosphate rock.

"The next thing is to wait, and the restoration process will take some time......"

"I guess it's ...... How many hours?"

Xu Le moved his muscles and bones.

Meng Yiyi jumped up, took a piece of small dried fish, and tore off thin strips of fish to tease the wolves.

Hearing Xu Le's words, she raised her little face and asked:

"So long?"

It's a long time, and it's fast in the chemical process...... That is, the amount I refine is small.

"It's ok. ”

Xu Le nodded in reply, then pointed to the small dried fish in her hand and asked, "Do they eat it?"

How do you feel stupid when Bai Tian feeds them, the wolves' expressions are disgusted......

Obviously, when I fed it just now, Erha's expression of eating dried fish was quite satisfied.

"I don't seem to like ...... very much."

Silly Bai Tian showed a look of wanting to sue the black, "Look!"

Under the ravages of the sea breeze and the scorching sun, her skin was still like white porcelain, leaving no traces.

The small white hand tore off a small piece of dried fish and held it up to the wolf lying beside her......

No...... It is lifted to a height of about ten centimeters from the top of the wolf's head.

Then Meng Yiyi was crisp:

"Claw!"

Xu Le: "???"

Although in front of me, the wolves behaved no different from domesticated domestic dogs......

But it's a wolf after all, right?

Or is it the kind that is really crazy in the wild and does not have any history of domestication.

At best, they treat you like one kind...... Maybe it's still a little she-wolf that hasn't grown up.

You just ask people to claw?

The claws are almost as big as your head......

And...... You stupid Bai Tian just teased this horse, but after he pounced on me head-on and was stabbed in the face by me, he still didn't know whether he was alive or dead......

It's already very face-saving if you don't bite......

"You see it's disobedient...... "Meng Yiyi didn't know this, she sued confidently.

"Ah, normal. ”

Only if you can be obedient can you have a ghost...... Xu Le held his hands and raised his chin, "Claws." ”

The reckless wolf flipped up, kicked and ran in front of Xu Le, then raised his left front paw and put it on the palm of the hand he handed out.

Meng Yiyi: "Ծ‸Ծ"

"It's not Cortana!"

"Cortana?"

"Uh-huh, my big dog at home. ”

Meng Yiyi stuffed the meat strips into her mouth, freed her hands, and spoke while chewing and gesturing:

"The heat is high, the heat is wide, but it's not fierce at all, it's good. ”

She slurred words and drew a huge figure twice as wide as she was and about as tall as hers.

Good...... It's so big...... Is that still a dog?

Xu Le asked with a faint pain in the back of his head, "What breed?"

"Rottweiler, that's why I call her Cortana!"

Ah, Rottweiler, to tell you a joke, Rottweiler is docile and not fierce at all...... What a fart!

Xu Le felt the back of his head hurt even more.

"Alright, stop playing. ”

He digressed the subject, "You go bake some dried fish and jerky and give them to them." ”

There are so many wolves, you can't cook...... It can only mean the meaning.

"What if they don't eat it?"

The cutie asked resentfully.

"I won't stop eating. Xu Le glanced at the wolves, and the wolves lowered their heads and whispered.

"Oh, good......" She stuffed the small dried fish into her mouth in two bites, turned around and ran to the place where the jerky was hung by the stone house to get the ingredients.

Wrong...... Your dried fish, is it still raw...... Xu Le stretched out his hand and hung in the air: "Don't ......"

I saw Meng Yiyi chewing and chewing, and then leaned her neck-

The whole dried fish went into her stomach.

...... Okay.

Xu Le continued to do his job.

Out of sight and out of mind......

He cut the wood into finger-length strips, three to five millimeters thick.

These strips are then soaked in melted plate oil at one end.

Then use a hacksaw to cut out a few small pieces of wood about 10 centimeters in length and about 2 centimeters or 5 centimeters in width.

The edges and corners of the small pieces of wood are also carved out with a carving knife with delicate mortise and tenon heads and eyes.

The pieces of wood are inserted into each other to create a palm-sized box with drawers.

The length of the grease-soaked strip at one end is about the same length as the small box.

After making the box, Xu Le took the sulfur block extracted from the ore a few days ago and crushed it into powder.

Then mix in a small amount of grease, stir into a paste, and dip the end of the stick with the oil in the mixture.

Barrage in the live broadcast room——

"Matches?"

"Really...... Sulfur is used as match heads, and what is to be refined from phosphate rock must be red phosphorus. ”

"The sulfur on the match head and the red phosphorus on the skin rub together to generate heat, and then you can light an open flame. ”

"There should be very few people who can use matches now, but on the island, this is another dimensionality reduction blow!"

"Come on, come on, come on, review a knowledge point: Now on the island, no more than half of the people have lit flames. Less than one-third of them can be stably ignited!"

"Yes, we all know that we drill wood to make fire, but if you really want to do it, that's not the same thing at all. ”

"The storm two days ago was really injured, and many anchors finally lit fires, but they were all extinguished by the rain, and they couldn't find dry wood to start the fire again!"

"Big Brother Xu Le, here is already groping for matches...... Comparisons are odious. ”

"If you can make a match, you really don't have to go anywhere to lift the torch, and when the time comes, go to a new place, and wipe the match—yi!"

"So inside that tin can, it's refining red phosphorus?"

“......”

Just over an hour!

The iron cans placed on the upper layer of the ventilation stove have been burned to a red temperature, and they are taken out and cooled.

A shallow notch is cut out of the seal with a chainsaw, and then a small hole is smashed with a stone, and the contents are poured out of the small mouth.

What fell out of the stumble was a pile of debris that had a dull gray-red color.

The debris is soaked and precipitated in water, and the red phosphorus particles with gray color are slightly visible in sieving out.

Crush it further!

Then mix the red phosphorus powder into a paste and spread it on the side of the small wooden box you just made.

Dried!

"The match is ready. ”

Xu Le held up the delicate small box, and the match stems he had just made were neatly stacked in the box.

Take out one and rub it vigorously across the red phosphorus powder layer -

...... ......

Yikes!

A small flame jumped and lit from the matchhead!

Xu Le blocked the wind with one hand and brought the flames closer to the camera-

"It's okay, although the purity of the materials is very problematic, but it can ignite after two or three strokes. ”

"And the burning is quite stable, which is very suitable for starting a fire outside the small courtyard. ”

Flame ...... Enchanted fire attributes?

Oh no, it still has to follow the science, and it takes all kinds of materials that have been collected so far.

It's not the kind of magical skill that can make the big sword burn with a swipe of your hand, and then you can go to the monster that has a lot of weak fire.

Feature Maintenance...... Activate the skill, and the material durability will not be reduced until the skill duration is over.

After that, all losses are returned immediately.

If the material is not exhausted, then the durability is lost, otherwise it will be scrapped directly......

The duration of 50,000 people is exchanged for one second...... [Instant] is the same?!

A match burned quietly and soon reached the end of the oil-soaked section.

The flames turned a dim red glow, then slowly extinguished.

There are still a lot of red phosphorus, and they continue to cut wooden strips and wood chips.

Plug in, soak in oil, dip sulfur match heads, and apply red phosphorus ignition coating......

On the island, there are more spare ignition tools, the better, Xu Le made more than a dozen boxes of matches for spare, placed them in the living room of the stone house, wrapped in leather, and isolated from external heat.

After all, the purity of red phosphorus is not guaranteed, and it is possible that it is mixed with some white phosphorus with very low ignition points.

If it is not stored well, the whole shelter will have to be set on fire.

As for the remaining red phosphorus and other materials, Xu Le simply struck while the iron was hot-

Attached to the fire!
