~： Sixty-eight, oil barrel

The flame in the mud stove has long been extinguished, and the twins had seen the fire when they came back, but unfortunately the charcoal ash was gone.

Now, I have to make fire again!

"I remember there was a flashlight in my backpack, right?" Zhao Yunxiang asked Han Qianluo, the backpack was on Han Qianluo's back.

"Well, here it is!" Han Qian quickly opened the zipper and took out a long, round flashlight.

The outer layer of this old-fashioned flashlight is bright white iron, and there are two No. 1 batteries inside, a convex lens, and an iris.

"Oh, yes, the convex lens of the flashlight can be used to make fire!" Lin Qingxuan was still melancholy just now. Now there is an answer to how to make fire.

Because there is no clock, I don’t know the current time, but depending on the position of the sun and the level of hunger, it is about 12 to 1:30.

During the day, count the venomous sun during this time period.

Zhao Yunxiang first took out the charcoal powder, which is very flammable. The charcoal powder is packed in a bottle, the bottle is sealed, and it will not get wet.

The other bottle is filled with trivial tinder. These are made of coconut shell tissue. The color is grayish-yellow. It contains a lot of oil and is flammable.

"When you survive, fire is particularly important. Preserving tinder is the foundation of survival. Of course, if you can preserve the flame, it would be best." Zhao Yunxiang quickly took apart the old flashlight, took off the convex lens, and the condensing circle also dropped. drop.

"This kind of old-fashioned flashlight is so troublesome, why did the condensing ring fall out?" Han Qianluo picked up the condensing ring that fell on the beach. This kind of thing is like a mirror, very bright.

"This kind of condensing ring can also be used to make fire, because it can condense light. The sun not only has brightness, but also heat. While concentrating the light, it can also gather heat." Zhao Yunxiang said.

"I remember I once watched a documentary. In some places where firewood is scarce, the sun is shining and the ultraviolet rays are particularly strong. People there use smooth metal to make an arc, and the heat collected by the arc can be used directly. Boiling water."

"I have also seen it, it seems to be a desert area. At that time, I thought the people there are so smart." Lin Qingyu nodded and said.

Human beings are advanced creatures with high intelligence. Zhao Yunxiang not only once felt that human beings might not be born directly on the earth.

The ancestors of primates cannot be studied. Of course, we don’t need to worry about these. Just live in the present, save resources and protect the ecology as much as possible.

start to make fire!

Zhao Yunxiang put the charcoal powder and tinder on a dry leaf, and then started to heat the charcoal powder with a magnifying glass.

Adjust the convex lens as much as possible, so that a very bright spot will appear. The smaller the spot, the higher the temperature.

When he was young, Zhao Yunxiang played with this kind of thing, which was used to burn ants.

How persistent is old Zhao?

used a convex lens to roast the ants to death, even to the point of smoking.

A few minutes later……

The small light spot of the convex lens ignites the charcoal powder, which is easily ignited.

"Wow..."

The sparks generated by the charcoal powder ignited tinder, which ignited the dry palm leaf debris, and finally the flame increased, burning the twigs and firewood.

fire!

The fire came again, and seeing this flower of flame swaying with dense smoke, the faces of several people bloomed with aunt-like smiles again.

With fire, we can proceed to the next step!

brought back a large piece of python meat. Although it was covered with bamboo leaves and leaves as much as possible, it could not hide the smell of flies.

This kind of fly, which is only the size of a mung bean, is very sensitive, and the sea breeze on the beach does not use it.

The most melancholy thing is the visceral fat of sharks!

Because the shark does not have a swim bladder, its liver is outrageously strong. The color of the liver is originally yellow like a yellow peach.

But after drying and ravages by flies, it doesn't look fresh at all, the color changes from bright yellow to dark yellow.

And this smell has a smell.

It has only been a few hours since sharks have been dissected. This kind of internal organs is the most prone to deterioration, especially the fatty ones.

This is the reason why the decay of the carcass starts from the inside, because the internal organs of all animals contain a lot of bacteria.

When a living being is alive, the bacteria will guard themselves and balance and protect themselves.

But once the creature dies, these bacteria are like wild horses, out of control.

"I remember, what do you seem to be doing with shark viscera?" Han Qianluo stared at Zhao Yunxiang and found that this man was standing in front of the shark viscera in a daze.

"Shark's internal organs contain a lot of fat. Shark oil can be obtained after refining. Shark oil has a great healing effect on trauma and scald." Zhao Yunxiang squinted at the sea in the distance.

"As the saying goes, people live by the sea, how can they not wet their shoes?"

"It's a person walking by the river, how can you not wet your shoes." Han Qianluo corrected.

"But the shark's internal organs smell weird." Lin Qingyu also stared at the greasy liver.

"Let's wash it. After washing it, let it dry, and then try to refine the oil." Zhao Yunxiang said, "We don't have any cooking oil yet."

"Can shark oil be eaten?" Lin Qingxuan asked with wide eyes in surprise .

"Can't..." Zhao Yunxiang returned softly.

"Then why do you say cooking oil?"

"When I saw the shark's innards, I thought of wild boar. The fat of wild boar can be refined or solidified."

"This brain circuit!" Han Qianluo smiled, expressing his conviction.

'S current job is to smoke shark meat and snake meat. The twins are responsible for washing the snake meat brought back with sea water, then slice it and smoke it.

If you don’t take quick measures, these raw meats will spoil before tomorrow, because the temperature and humidity on the desert island will spoil the food in a short time.

Although the smoked meat tastes hard and tastes not so fresh, it is better than nothing.

"In other words, do we have to refine oil?" Han Qianluo carried the washed shark liver. Even after it was washed, the liver still smelled very oily.

"Well, oil refining is urgent." Zhao Yunxiang looked at the container in the shelter, a drum of cooking oil, a stainless steel basin, and an electric pot.

First of all, the electric cooker is directly eliminated. Bringing this thing back is the fate of being taken apart. Lao Zhao only wants the inner pot of the electric cooker. The lines below the pot body are all useless. There is no electricity here, only fire! ! !

Stainless steel basin was also excluded. Although this container is a basin, it is used as a pot and eaten!

Finally, half a half-meter deep oil drum can be used!
