Chapter 454 Red Mud
"Mud?" Leonardo repeated hesitantly.
What do you do with mud? Doesn't it mean making a fire and then burning the soil into pottery?
Finally, he was so brittle that he used the sharp fragments as weapons?
Leonardo thought about the broken porcelain at home. It was indeed very sharp...
[Who said before that the next step is to make weapons, the Prophet's Blade]
[Is it a stone spear? ]
[Didn't you hear Fang Shen say he wanted to make ironware before he came? Just start the furnace and smelt iron! ]
Bifang didn't reply, but sniffed the air with his nose twitching, and said in amusement: "How much insect repellent did you apply? The smell is choking."
Leonardo was a little embarrassed: "I can't help it, there are too many mosquitoes here."
He suspected that if he was just like Bifang, not wearing any clothes and not using insect repellent, he would probably be sucked to death by mosquitoes once he stopped.
Even when she was sitting on the ground weaving shoes just now, Bifang was driving away mosquitoes while weaving.
If this were not the case, the shoes could be made even faster.
[I remember Fang Shen said a long time ago that to find water sources, look for animals and insects. Go to places with many mosquitoes and you will often find rivers.]
[Yes, I remember this too. I think it was said in Qinling Mountains.]
[The people in front are all old fans]
"Yes, mosquito larvae are completely aquatic, so as long as there is a small pool of water, such as a small flower pot on the balcony, it can reproduce in large numbers."
An adult female mosquito lays eggs in stagnant water and can lay more than 300 eggs at a time. As long as you leave it alone and keep water in the container, it can reproduce.
The eggs will hatch into larvae after 24-48 hours in the water, and will complete their development after about 10 days. Finally, the fully developed mosquitoes will become adults after about 2 days, and will start to forage for food soon after.
It can be described as wild growth.
Not to mention that it is in the rain forest, where the moisture is so abundant that even puddles are not needed, some moist soil will do.
【I have always hated mosquitoes! 】
[How could God create such a devilish creature? ]
[In order to fill the gap of no mosquitoes in my country in winter, a scientist finally developed a cold-resistant mosquito]
[I have seen this news. He should be taken away and cooked! ]
【Give me a piece of the pie! 】
[In fact, after filling the gaps, there will be a lot more food, which will help animals survive the cold winter and is very beneficial to ecological protection... I can't make it up anymore]
"It's because there are too many mosquitoes that we have to make weapons to resist them." Bifang, who had put on his shoes, waved his hand, motioning Leonardo to follow.
At the same time, he looked around and indeed found a broken branch.
Remove all the extra branches and you will have a nice tree stick.
"Because there are too many mimicry animals in the rainforest, and the dark environment makes it easy for you to fall into their trap, so a good stick will become particularly important at this moment, it can help us to 'scare the snake away'."
"You can also prepare one. After all, our routes are not completely overlapping." Bifang looked at Leonardo behind him and suggested seriously.
Leonardo smiled, turned his head to look around, and also learned to pick up one, but it was not as straight as Bifang's, and its appearance was a little worse.
【La la la, late but here we are】
[I knew it, I knew it! ]
【You can always trust a straight stick! 】
[If you get lost in the rainforest, don't panic, calm down and find a straight stick to use as a weapon! ]
[You have obtained the artifact, go find a beast and try it out! ]
"Where was I just now?" Bifang picked up the stick and was interrupted by netizens. He forgot what he was talking about.
"Mosquitoes, you said you wanted to make weapons out of mud to fight off mosquitoes," Leonardo added.
In connection with the soil that Bifang mentioned, Leonardo had already vaguely guessed something.
Leonardo is not completely ignorant. He has traveled all over the world and met many different people, even in Africa: "Are you going to get smeared with mud?"
Bifang raised his eyebrows but did not deny: "Have you been to Africa?"
Leonardo nodded. "I've filmed a movie somewhere before and saw the locals do this. To be honest, I think it's quite primitive. They even use mud to take a bath."
Bifang remained silent, but netizens were scratching their heads, feeling that they could not understand this alien communication.
Mosquitoes, dirt, Africa?
What are you talking about?
"Do you know which animal kills the most people in the world?" Bifang did not give a direct answer, but asked the audience.
What is it?
Before the audience could react, Bifang had already given an example: "Great white shark? Lion? Tiger? Or poisonous snake? Poisonous spider? In fact, none of them. The ones that kill the most people have always been mosquitoes."
mosquito?
The audience was stunned, but many people reacted.
disease!
That’s right, no creature spreads disease better than mosquitoes!
"Many people may not understand, but in fact, the website 'Life Science' once ranked the world's 10 most deadly animals, which pose the greatest threat to human life. But what is incredible is that the world's most deadly animal is not a crocodile, a great white shark or an African lion, but an inconspicuous mosquito. You would never have thought that the most dangerous animal in the world is actually a mosquito. At present, except for Antarctica, there are different kinds of mosquitoes everywhere on the earth. In most cases, a mosquito bite will only make you feel itchy, but some mosquitoes carry malaria parasites. This is a parasitic disease, and the pathogen is called Plasmodium. After entering the human body, Plasmodium will parasitize in the red blood cells in the human body. People infected with malaria will have symptoms of alternating hot and cold, which is called 'shaking fever' in many places in China. More than 2 million people die from malaria every year in the world, and mosquitoes are the culprit. Therefore, it is well deserved to say that mosquitoes are called 'the number one killer of mankind', and it is very necessary for us to make 'weapons' to resist it."
Two million people died!
Oh shit.
The audience was all shocked to hear this extremely exaggerated statistic. Are there still diseases in modern society that can kill millions of people?
"Everyone who can see my live broadcast is actually very lucky, because this means you still have a mobile phone, a computer, a TV, and society can still provide you with a good network environment. These are things that many people cannot have or even see."
"Banna is a high-incidence area for dengue fever, which is mainly transmitted by mosquito bites. On the first day Leonardo and I came to Banna, local news reported that someone had been infected with dengue fever again this year. This disease spreads very quickly, so we must be careful."
Bifang sighed, still remembering the frown on Director Zhou's face when he heard about this.
"In a good economic environment, sanitary conditions are excellent, but in many parts of Africa, the locals do not have such good conditions. I know an indigenous tribe that knows how to resist mosquitoes."
"In short, it is to apply mud all over the body, using the smell and thickness of the mud to repel mosquito bites."
"In some very backward places, if even this kind of soil is not available, some Africans will directly apply animal feces. Although it has a certain effect, this method is unacceptable."
When the audience heard Bifang say that he would rather smear feces on himself to avoid mosquito bites, they completely understood how terrible mosquitoes are.
This is a situation that has never been encountered in any previous adventure.
Only in the face of death can people let go of their shame and smear the dirtiest things.
"Why not find some herbs to repel mosquitoes? With your ability, this shouldn't be a difficult task, right?" Leonardo was a little curious.
He had watched all of Bifang's live broadcasts, and as a Chinese, it was not difficult for him to find herbs to repel mosquitoes.
Why do we have to apply mud?
It would be a shame to cover such a nice figure with mud.
[Yes, why do we have to apply mud? ]
The audience is also very curious, but is there any need to do this?
"How long can the toilet water last?" Bifang did not answer directly, but turned to ask the audience.
[Um, a few hours? ]
[It feels like hours...]
[Once you start sweating, it won’t have much effect. ]
"Isn't that the reason?" Bifang smiled. "Common products used in modern industry cannot effectively repel mosquitoes. Sweating and moving will reduce the effect, not to mention the mosquito repellents found in the forest. They are not useless, but they are very limited and will leave a very obvious smell on our bodies."
Ninety-nine percent of any material that can be directly used in nature is inferior to industrial products.
There is a reason why human society has developed for so long.
The more original it is, the better it is.
Using herbs to repel mosquitoes is also very troublesome. You have to do it again every once in a while, and make tools to crush them to get the juice.
It is more practical to apply a layer of mud, which is not only easier to find, but also more effective. One is chemical isolation and the other is physical isolation .
"In Africa, there are plants that can repel mosquitoes. People call them 'mosquito-proof trees.' Most indigenous people in Africa choose to build their houses near these trees or plants."
"But apart from that, Africans still smear mud on their bodies, which can prove a lot of things. What we are going to find now is this kind of mud, red mud."
"Red mud, which literally means red mud, is mainly composed of red soil, a terrestrial material carried by rivers. It is rich in iron oxide. If anyone has worked in a ceramic factory, they will know that this is also a common pottery material."
"So this time, we are looking for both red mud and water!"
