Wire sawing trees, it's unbelievable to think about.

In people's perception, only a sawblade with a serrated shape can cut off a tree.

The wire is basically smooth, there is no serration, and the friction is super small.

The wire is about three meters, and after calculating the thickness of the bamboo, Zhao Yunxiang broke the wire, about half a meter.

After the flame burning, the iron wire is naturally cooled, the toughness is enhanced, and the hardness is reduced a lot.

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

Because the toughness has increased significantly, when the wire is broken, Zhao Yunxiang repeatedly folds it in half several times before breaking the wire.

If you do it just now, it is estimated that the wire will be broken if it is folded in half less than 3 times.

The work continues!

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

It's like twisting a twist!

The half-meter-long iron wire is made into a circle, about 25 centimeters, and even if it is twisted into a twist, this length will not deviate too much.

"This is the saw!" Zhao Yunxiang let Han Qianluo take a look, the wire ring completely turned into a twist, and the two branches were stuck at both ends of the wire twist.

These two branches are the handles of the saw, which is the wire that has been twisted into twists.

"Can this really cut bamboo?" Han Qianluo expressed doubts, you must know that the outer skin of the bamboo is very hard, although it is hollow, but it is difficult to see the bamboo with this smooth wire twist rope.

"It should be possible!" Zhao Yunxiang prepared very comprehensively, in order to prevent the wire from generating heat when sawing bamboo, which would affect the toughness of the wire, he deliberately poured a bottle of seawater, which could cool the wire and prolong its service life.

After all, these are two wires screwed together, and I will have to pull the sawed bamboo like a leather strip later, and the pressure of the wire twist rope can be imagined!

Come to the Bamboo Forest!

I chose a moso bamboo that grows on the slope, this bamboo is very old, and the outer diameter of the bottom layer alone is the thickness of 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 was incredulous, who would have thought that a twisted wire would have such great power.

The bamboo is sawed halfway, because it is hollow, it is still more labor-saving to saw, because the contact point of the hollow bamboo is small, and the wire saw is not very difficult.

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

"Whoa~!"

A bamboo fell down violently, Zhao Yunxiang stroked the saw, but felt a trace of warmth, and the temperature generated by friction had little effect on the wire.

After sawing off a dozen bamboos, the wire saws also went on strike!

"Click~!"

A bamboo is sawn halfway, and the saw breaks from the middle, after all, this is a wire, and the sawed bamboo is like a slow fold in half, and the saw has cracks in many places, as if it is unusable.

"It's a pity, it's still broken...... Han Qianluo is still cooling down the saw while holding the bottle, she already knew in her heart that the saw would break, but she didn't expect that she could cut more than 10 bamboos.

"It's a lot...... Zhao Yunxiang picked up the wire, this is a rare treasure, save it, and if you have a chance in the future, see if you can smelt it, even if it can't be smelted, after it is red, the hammer can also make the iron bind.

It is indeed difficult to smelt iron, which was only smelted in 1500 BC, and it is difficult to make.

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

The 20-meter-long bamboo is sawn into three sections, one of which is about 7 meters long.

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

First you have to be half a meter away from the ground, then you have to sleep on the first floor, and you have to ...... on the second floor. Make a baby, eat barbecue in the open air on three floors, or watch the stars and the moon.

When more than 10 bamboos were segmented, 3 saws were broken again, and it can only be said that the wire was seriously rusted and corroded.

"It's a bit unexpected. Zhao Yunxiang propped his head with one hand and drilled into his hair with his hand, and now there were only two wires left, which could not be completed even if they were made into saws.

Of course, building a house is a big project, and it needs to be done when there is plenty of food.

Now......

Fresh water is available, and the food is the giant blue flag tuna by the sea, which needs to be smoked if it wants to be stored for a long time.

The first priority was to make a smokehouse first, and then use the bamboo to make a simple shelter.

The devil knows if it will rain again at night!

The tuna has been placed a little longer and has begun to attract flies.

The flies on the desert island are very small, even smaller than some mosquitoes in the forest, and this species of fly is really rare.

But their sense of smell is very sensitive, and there are at least a dozen flies crawling on the tuna, and no matter how much you catch them, you can't get rid of them.

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

After all, maggots eat carrion!

"Let's make a smokeroom first, it's the kind of dual-use, housing and smoking in one. Zhao Yunxiang picked up a few bamboo poles and began to think about how to make a house in his mind.

A simple tripod would be nice, but the size of the smoker chamber is too small to smoke all the fish.

After all, this tuna weighs more than 100 pounds!

After some thought, Zhao Yunxiang planned to build a small house, first using the mortise and tenon method to connect the frame of the house.

To put it simply, it is to connect eight bamboos with a length of 7 meters using the mortise and tenon method.

The connection is as simple as burning charcoal to make a hole in the thick bamboo, which is about the thickness of another bamboo.

Charcoal burns bamboo, and under the operation of a blowing stick, the charcoal with fire burns quickly, and it only takes a few minutes to burn a hole.

The hole is then drilled with an angular stone to the thickness of another bamboo.

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

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

Most importantly!

The nearest tree is about 10 meters away.

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

This cube was originally intended to make a three-story sea view house, but now we still have to take it step by step, first to make a roof that shelters from the wind and rain, and then to make the wall.

Roofs and walls that shelter from the wind and rain are not suitable for bamboo, because the current saws cannot see bamboo, so they can only be replaced by other things.
