Divine Desert Island Survival System

　　I saw a tree with a wire, it's incredible to think about it.

　　 In people’s perception, only a saw blade with a saw blade can cut a big tree.

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

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

　　After being burned by flame, the iron wire naturally cooled down has increased toughness and reduced hardness.

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

　　Because of the substantial increase in toughness, when the wire was broken, Zhao Yunxiang repeatedly folded the wire in half before breaking the wire.

　　If you change it to just now, it is estimated that the wire will be broken in less than 3 times.

　　 Work continues!

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

　　 is like twisting a twist!

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

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

　　 These two branches are the handles of the saw, and the saw is a wire twisted into a twist.

　　 "Can this really cut bamboo?" Han Qianluo expressed doubts, knowing that the outer skin of moso bamboo is very hard. Although it is hollow, it is difficult to see bamboo with this smooth wire twist rope.

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

　　 After all, these are two iron wires twisted together. Later, I will pull the saw bamboo like a leather strap. The pressure of the iron wire twist rope can be imagined!

　　 came to the bamboo forest!

　　 chose a bamboo that grows on the slope. This bamboo is very old, and the outer diameter of the bottom layer has the thickness of the wrist.

Ready!

　　 Zhao Yunxiang slowly pulled the wire saw, alternately back and forth, the twist-shaped wire slowly gnawed the bamboo skin, and then some sawdust appeared.

　　 This is sawdust!

　　 "It's really possible!" Han Qianluo couldn't believe it. Who would have thought that a wire twisted into a twist could have such a powerful force.

　　Moso bamboo is half-saw, because it is hollow, it is relatively labor-saving, because the hollow moso bamboo has a small contact point, and the wire saw is not very laborious.

　　 If it's a sawn tree, it's a different matter!

　　 "Wow!"

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

　　 After cutting a dozen moso bamboos, the wire saw went on strike!

　　 "Crack~!"

　　 A bamboo tree was sawed in half, and the saw was broken in the middle. After all, this is a wire. The sawing of bamboo is like slowly folding in half. This saw has cracks in many places, and it seems to be useless.

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

"It's a lot..." Zhao Yunxiang picked up the iron wire. This is a rare treasure. Save it. If you have the opportunity in the future, see if you can smelt it. Even if it can't be smelted, hammering can make the iron hot. combine together.

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

　　 Because the saw broke, Zhao Yunxiang made another saw to disassemble the sawn bamboo.

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

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

　　 First, you have to get off the ground for half a meter, then sleep on the first floor, then make a baby on the second floor, eat barbecue in the open air on the third floor, or watch the stars or the moon.

　　 When the 10 pieces of bamboo were segmented, three saws were broken again. It can only be said that the iron wire is rusted seriously and the conditions of corrosion are different.

　　 "The situation is a bit unexpected." Zhao Yunxiang propped his head with one hand and dipped his hand into his hair. Now there are only two iron 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 needs to be completed with plenty of food.

　　 Now...

　　 There is a source of fresh water. For food, it is the huge blue flag tuna by the sea. This fish needs to be smoked for long-term preservation.

　　The top priority is to build a smoking room first, and then use these bamboos to make a simple shelter.

　　 Ghost knows if it will rain again at night!

　　 The tuna is a bit longer because it is placed, and it has begun to attract flies.

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

　　 But their sense of smell is very sensitive. There are at least a dozen flies crawling on the tuna.

　　 In desperation, I can only temporarily soak the tuna in the sea water, because contact with air will attract flies, and the flies will lay eggs on it. Once the eggs are laid, it will accelerate the deterioration of the meat.

　　 After all, maggots eat carrion!

　　 "Let’s make a smoking room~www.wuxiahere.com~ which is the kind of dual purpose, housing and smoking integrated." Zhao Yunxiang picked up a few bamboo poles, and began to think about how to make a house.

　　 It would be better to simply make a tripod, but the smoking chamber of this triangle is too small to completely smoke all the fish.

　　 After all, this tuna weighs more than 100 catties!

　　 After several thoughts, Zhao Yunxiang plans to build a small house, first using the tenon and tenon method to connect the frame of the house.

　　 To put it simply, eight bamboos of 7 meters in length are connected by tenon and tenon.

　　The connection method is very simple. It is to burn a hole in the thick bamboo with burning charcoal. The hole is almost the thickness of another bamboo.

　　 Charcoal can burn bamboo. Under the operation of a blowing stick, the charcoal on 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.

　　 One hour later, the cube frame was completed. 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 near the beach.

the most important!

　　The nearest tree here is about 10 meters away.

　　 This way, even if lightning splits the tree, there is no need to worry that it will hit the shelter.

　　 This cube was originally intended to make a three-story ocean view room, but now it has to be done step by step, first to make a wind-proof roof, and then to make the walls.

　　 The roof and wall covering the wind and rain are not suitable for bamboo, because the current saws can’t cut bamboo and can only be replaced by other things.
