The fiber layer of the dogwood tree is very tight, and the rope made of it is very flexible, which is very suitable for climbing, setting traps, etc., and can also be used as a rope to build a house.

"Look what I've found!" Hu Xiaodao rubbed a rope five or six meters long on his back, and when he passed through a crack in a mountain, he accidentally found a red stone.

"Hahaha, this is a piece of red jasper, its composition is mainly various colors of siliceous minerals such as chalcedony, quartz, etc., the particles are small, the structure is compact, the refractive index is 1.54, the Mohs hardness is 6.5-7.0, and the relative density is 2.7-2.95 grams / cubic centimeter.

Siliceous minerals, hardness, not easy to weather, not easy to wear, not afraid of acid and alkali erosion. So, if this stone can be made into a knife, I'll put it away first! ”

The rainforest, which is useless in the eyes of others, is a big treasure trove in the eyes of Hu Xiaodao, a wilderness survival expert, and any resources that can be used must be collected.

"Now that I'm on a relatively low ground, I suddenly remember an ancient poem!" Thinking of this, Hu Xiaodao suddenly cleared his throat.

"Ah~~ Matsushita asks the boy"

"The teacher of words picks medicine"

"The clouds are deep and I don't know where"

"Only in this mountain"

The cynicism of the students who read aloud is sonorous and full of passion, as if they have forgotten that they are in the South American rainforest, and this cynical attitude greatly stimulates the visitors in the live broadcast room.

After finishing the bag, looking at the gradually fogging scenery in front of him, Hu Xiaodao said: "The temperature has dropped significantly, and I'm starting to worry a little about the temperature tonight——"

Hu Xiaodao, who was still full of anger just now, was also startled in the face of the sudden temperature change. At this altitude, with such low temperatures, he had no idea if he would be able to see the sun tomorrow.

Know that the higher the altitude, the lower the temperature. Because the main direct heat source of the tropospheric atmosphere is the ground, the farther away from the ground, the less ground radiation is obtained, and the lower the temperature. For every 100 meters of ascent, the temperature drops by 0.6 degrees Celsius.

Hu Xiaodao is located in the rainforest area, and the temperature is likely to drop even more, so for the sake of his life, he can only go down the mountain.

But Hu Xiaodao forgot one thing, that is, the jungles of South America are generally no man's land, and all kinds of thorns and vines seriously affect his progress.

"Guys, if I had a machete right now, I might be twice as fast, but unfortunately I don't have any of these things right now!"

It took some physical strength to just collect the rope, and I felt that my physical strength was lost quickly when I worked hard at a high altitude, and Hu Xiaodao knew this, but unfortunately there was no way.

Without a rope, you can't even climb down some of the higher cliffs. However, for the sake of safety, it is okay to spend some time, but fortunately, there are many dogwood trees, and it is most important to save your life when you meet a higher cliff.

I was really afraid of something, and not long after walking, Hu Xiaodao squatted on the edge of a cliff and calculated the distance.

The rope on the body is about six meters, and the cliff is about four meters high, which is said to be enough, but the nearest tree is also five meters away.

"Guys, my height plus the length of the rope I used to bind it, I'm probably a little more than two meters off the ground, although it's not too high, but the terrain down here is not flat, and those rocks are likely to hurt my feet."

Putting down the backpack, Hu Xiaodao took the rope off his shoulder, and after carefully measuring one side again, he began to tie the rope on the nearest tree.

It is said that the thick mouth of the bowl does not need to cost much rope, but for the sake of safety, Hu Xiaodao calculated twice before determining the length of the bundle.

Hu Xiaodao really wanted to go back to the jungle to find two tree vines to come back, and use the tree vines to slide down, after all, the tree vines were long enough, but unfortunately there was no machete in his hand, and he hoped that it might take more than ten minutes for the red jasper to be cut, and he didn't have time to wait.

Hu Xiaodao actually got a relatively thin tree vine and sent the backpack down safely, so that he lost a few pounds of weight on his body.

Through the basic consideration of mental arithmetic and safety, the part of the Hu knife used for rope binding is measured to be about 55 centimeters, which is already the limit position of safety.

In order to increase the sense of security, Hu Xiaodao also deliberately lit a lot of damp leaves and weeds at the stone where the rope came into contact with the cliff to reduce the friction between the rope and the stone and increase the safety factor.

"Guys, I'm going down now, it turns out that I started to rub these few meters of rope correctly, good luck to me!" Hu Xiaodao, who was in the sad backpack, saluted playfully, groped and went down the cliff.

Gripping the rope with both arms and feet crossed together in an S shape to increase friction, the dogwood tree's fiber layer is hard-wearing, but there are no gloves on your own hands, and the headset shows how difficult it can be.

The whole picture is falling little by little, and the more than 4 million people in the live broadcast room are worried.

"This stupid boy, why don't you learn to look at stones? Go read the book! ”

"Mom, Hu Xiaodao live broadcast, don't make trouble, I'm falling off the cliff now, it's too exciting!"

"What? I'll take a look at ......"

"Hold the grass! Hold the grass! ~ It's so scary, come and see, brother, King Sao has a special death! ”

"What a strong man...... Oh buy ga! ”

At this time, Hu Xiaodao tried his best to control his breathing to prevent his hands from slipping and falling, although four meters high is nothing in the city, but in this strange rocky mountain is not so fun.

His feet couldn't reach the rope anymore, so Hu Xiaodao used his hands hard at this time, grabbed the rope hard and slowly lowered his body.

When I grabbed the last ten centimeters, the rope on it suddenly loosened a little.

The maximum load-bearing capacity of a rope is not the place at the beginning, but the position at the end, and the endurance of the cornus tree fiber layer that Hu Xiaodao hastily rubbed up is definitely not particularly strong.

If it weren't for the fact that there were a lot of leaves and weeds on the edge of the cliff, the swinging rope would have been worn out long ago.

At this time, Hu Xiaodao didn't have time to think about it, but a picture flashed in his mind, if he had thrown some weeds and leaves down to slow down the impact before this, he would have been better, but after thinking about it, it wouldn't work at night.

After all, leaves and weeds will cover the protruding rocky parts, and if you jump off yourself, you are very likely to be injured, which is not what Hu Xiaodao wants.

In a hurry, Hu Xiaodao took a deep breath of fresh air, let go of his hands, and his body fell straight down to the rock about two meters above the ground.

"Puff ......" body and the rock came into close contact.

Hu Xiaodao's first reaction was to stand up and check his body to see if he was injured.

Fortunately, the place where it fell was only five centimeters away from the ten centimeters of the rock next to it, and if it deviated by another three or four centimeters, Hu Xiaodao might be injured.

"Hahaha, everyone, have you seen it, Brother Xiaodao, I came down unscathed!" happily picked up the backpack next to him and laughed.
