Divine Desert Island Survival System

It's incredible to think about sawing trees with wire.

In people's cognition, only with a jagged saw blade can cut a big tree.

The iron wire is basically smooth, without serrations, and the friction is super small.

The wire was about three meters long. After calculating the thickness of the moso bamboo, Zhao Yunxiang broke the wire, about half a meter long.

After being burned by flames, the iron wire that cooled down naturally has increased toughness and reduced hardness a lot.

This belongs to annealing in heat treatment, the purpose is to reduce the hardness of the metal and increase the toughness.

Because the toughness has greatly increased, when breaking the wire, Zhao Yunxiang repeatedly folded it in half several times before breaking the wire.

If it was done just now, it is estimated that the wire will break if it is folded in half less than 3 times.

The work continues!

Take a half-meter-long iron wire, circle it into a circle, place a branch at both ends, and start twisting the wire.

It's like twisting a twist!

A half-meter-long iron wire is made into a circle, which is about 25 centimeters. Even if it is twisted into a twist, the length will not deviate too much.

This is a saw! Zhao Yunxiang told Han Qianluo to take a look. The wire circle was completely turned into a twist, and two branches were firmly stuck on the two ends of the wire twist.

These two branches are the handle of the saw, and the saw is twisted wire.

Can this really saw through bamboo? Han Qianluo expressed doubts. You must know that the outer skin of moso bamboo is very hard. Although it is hollow, it is difficult to saw bamboo with this smooth twisted wire rope.

It should be possible! Zhao Yunxiang was well prepared. In order to prevent the iron wire from generating heat when sawing bamboo, which would affect the toughness of the wire, he deliberately poured a bottle of sea water to cool down the wire and prolong its service life.

After all, these are two wires twisted together, and later you will have to pull and saw bamboo like a pimp, the pressure of the twisted wire rope can be imagined!

Come to Bamboo Forest!

I chose a moso bamboo growing on the slope. This bamboo is very old, and the outer diameter of the bottom layer alone is as thick as a wrist.

Ready!

Zhao Yunxiang slowly pulled the wire saw, alternating back and forth, the twisted wire slowly gnawed at the skin of the bamboo, and then some sawdust appeared.

It's sawdust!

It's really possible! Han Qianluo couldn't believe it. Who would have thought that a twisted wire could have such great power.

The moso bamboo is half-sawed. Because it is hollow, it is relatively labor-saving to saw. Because the hollow moso bamboo has small contact points, the wire sawing does not take much effort.

If it's sawing trees, that's a different story!

Wow~!

A moso bamboo fell suddenly, Zhao Yunxiang caressed the saw, but felt a little warmth, the temperature generated by the friction had little effect on the iron wire.

After sawing through more than a dozen moso bamboos, the wire saw also stopped working!

Crack~!

A bamboo was sawed halfway, and the saw broke in the middle. After all, it was an iron wire. Sawing bamboo was like slowly folding in half. The saw had cracks in many places, and it seemed to be unusable.

It's a pity, it still broke... Han Qianluo was still cooling the saw with the bottle in hand. She knew in her heart that the saw would break, but she didn't expect to be able to cut through more than a dozen bamboos.

A lot... Zhao Yunxiang picked up the iron wire. This is a rare treasure. Save it. If you have a chance in the future, see if you can smelt it. combine together.

It is indeed difficult to smelt iron. You must know that iron was only smelted in more than 1500 BC, and it is very difficult to make.

Because the saw was broken, Zhao Yunxiang made another saw and used it to disassemble the sawn bamboo.

20 meters long bamboo sawn into three sections,

The length of one section is about 7 meters.

This is the structure of the bamboo house. After all, Zhao Yunxiang wanted to make a three-story bamboo house villa.

First of all, you have to be half a meter off the ground, then sleep on the first floor, make babies on the second floor, eat barbecue in the open air or watch the stars and the moon on the third floor.

When more than 10 pieces of bamboo were segmented, three saws were broken again. It can only be said that the iron wire was seriously rusted, and the corrosion situation was also different.

The situation is a bit unexpected. Zhao Yunxiang supported his head with one hand, and his hand got into his hair. Now there are only two wires left. Even if these are made into saws, they cannot complete the construction of the house.

Of course, building a house is a big project, and it can only be completed when there is plenty of food.

now...

The source of fresh water is available, and the food is the huge blue flag tuna on the seashore. This fish needs to be smoked to be preserved for a long time.

The first thing to do is to make a smokehouse first, and then use these bamboos to make a simple shelter.

Who knows if it will rain again at night!

Because the tuna has been placed for a long time, it has begun to attract flies.

The flies on the deserted island are very small, even smaller than some mosquitoes in the forest. This kind of fly is really rare.

But their sense of smell is very sensitive. There are at least a dozen flies crawling on the tuna, and no matter how hard they try to drive them away, they cannot be driven away.

In desperation, the tuna can only be temporarily soaked in sea water, because the contact with the air will attract flies, and the flies will lay eggs on it, and once they lay eggs, it will accelerate the decay of the meat.

Maggots eat carrion, after all!

Let's build a smokehouse first, the kind that is dual-purpose, where housing and smoking are integrated. Zhao Yunxiang picked up a few bamboo poles, and began to conceive how to build a house in his mind.

It would be great to simply make a tripod, but the smokehouse pattern of this kind of triangle is too small, and it may not be able to completely smoke all the fish.

After all, this tuna weighs more than 100 catties!

After thinking about it for a while, Zhao Yunxiang planned to build a small house, and first connected the frame of the house with the method of tenon and tenon.

To put it simply, 8 pieces of bamboo with a length of 7 meters are connected by tenon and tenon.

The connection method is very simple, that is, burn a hole in the thick bamboo with burning charcoal, and the hole should be about the thickness of another bamboo.

Charcoal can burn bamboo. Under the operation of a blowing stick, the charcoal with fire burns quickly, and a hole can be burned in just a few minutes.

Then use an angular stone to drill the hole to the thickness of another bamboo.

An hour later, the frame of the cube was finished. Han Qianluo and Zhao Yunxiang lifted it up and found a suitable place to put it down.

The soil here is still sandy land, far away from the jungle and close to the beach.

the most important!

The nearest tree here is about 10 meters away.

In this way, even if the lightning splits the trees, there is no need to worry about harming the shelter.

This cube was originally intended to be a three-story sea-view house, but now it has to be done step by step, first to make a roof that protects against wind and rain, and then to make walls.

Bamboo is not suitable for roofs and walls that shelter from wind and rain, because the current saws cannot cut bamboo, so other things can only be used instead.
