What is the operation of making clay? Doesn't it mean lighting a fire and then burning the soil into pottery?
Finally got brittle and used sharp shards 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 Knife]
【Is it a stone spear? 】
[Didn’t you hear Fang Shen say that he wanted to make iron tools before he came? Just open the furnace and make iron! 】
Bi Fang didn't reply, his nostrils twitched, he sniffed the air gently, and said happily: "You have applied so much insect repellent water, the smell is choking your nose."
Leonardo was a little embarrassed: "I can't help it, there are too many mosquitoes here."
He suspected that if he were like Bifang, wearing no clothes and not using insect repellent, he would probably be sucked to death by mosquitoes once he stopped.
Even when he was sitting on the ground knitting shoes just now, Bifang was knitting and driving away mosquitoes at the same time.
If this were not the case, the production speed of shoes could be even faster.
[I remember Fang Shen said a long time ago that looking for water sources depends on animals and insects. If you go to places with many mosquitoes, you can often find rivers]
[Yes, I remember this too, I think I said it when we were 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 breed.
The eggs will hatch into larvae in 24-48 hours in the water, and will develop into larvae in about 10 days. Finally, the fully developed mosquitoes will become adults in about 2 days, and will begin to feed soon after.
It can be called a barbaric growth.
Not to mention being in a rainforest, the water vapor here is so rich that you don’t even need a puddle, just moist soil will do.
【I have always hated mosquitoes!】
[How could God create such a devilish creature?]
[In order to fill the gap in the absence of mosquitoes in winter in my country, a certain scientist finally developed a cold-resistant mosquito]
[I’ve seen this news, I should cook it now!]
【Give me a piece of the pie!】
[In fact, after filling the vacancies, there will be a lot more food, which will help animals survive the cold winter, which is very beneficial to ecological protection... I can’t make it up anymore]
"It's because there are too many mosquitoes, so we have to make weapons to resist them." Bifang put on his shoes and waved his hand, motioning for Leonardo to follow.
At the same time, he looked around and found a broken branch.
Pull off all the extra branches, and a good tree stick will appear.
“Since there are too many mimic animals in the rainforest, and the dark environment makes it easy for you to get tricked, a good tree stick will become particularly important at this moment, as it can help us ‘alert the grass and the snake’.”
"You can also prepare one, after all, our routes are not completely overlapping." Bi Fang looked at Leonardo behind him and suggested seriously.
Leonardo smiled, turned around and looked around, and also picked up one, but it was not as straight as Bifang's, and the appearance was a bit different.
【La la la, late but arrived】
【I know it, I know it!】
【You can always trust a straight stick!】
[If you get lost in the rainforest, don’t worry, calm down and find a straight wooden stick to use as a weapon first!]
[You have obtained the artifact, go find a beast and try it!]
"Where did I just talk?" Bifang picked up the tree stick and was interrupted by a netizen. Bifang even forgot where he had talked.
"Mosquitoes, you said you should use soil to make weapons to ward off mosquitoes." Leonardo added.
Relating to the soil Bifang mentioned, Leonardo had vaguely guessed what it was.
Leonardo was not ignorant. He traveled around and met many different people, even Africa: "Are you going to apply mud?"
Bi Fang raised his eyebrows but did not deny it: "Have you been to Africa?"
Leonardo nodded: "I have filmed movies somewhere before, and I have seen locals doing this. To be honest, I think it is quite primitive. They even use mud to bathe."
Bi Fang was noncommittal, but netizens scratched their heads, feeling that they did not understand this alien communication.
Mosquitoes, dirt, Africa?
What and what.
"Do you know what is the most murderous animal in the world?" Bi Fang did not answer directly, but asked the audience.
What is it?
Before the audience could react, Bi Fang already gave an example: "Great white shark? Lion? Tiger? Or poisonous snake? Poisonous spider? In fact, none of them. Mosquitoes have always been the ones that kill the most people."
mosquito?
The audience was stunned, but many people reacted.
disease!
That’s right, nothing spreads disease more than mosquitoes!
"Many people may not understand, but in fact, the website 'Life Science' once rated the 10 most deadly animals in the world, which pose the greatest threat to human life.
But what is incredible is that the most deadly animals in the world are not crocodiles, great white sharks and African lions, but the humble mosquito.
Unexpectedly, the most dangerous animal in the world is actually a mosquito. Currently, except for Antarctica, there are different types of mosquitoes everywhere on the earth. In most cases, a bite from a mosquito just makes you feel itchy, but some mosquitoes carry
Plasmodium. This is a parasitic disease, and the causative agent of the disease is called Plasmodium.
After the malaria parasite enters the human body, it will parasitize in the red blood cells of the human body. People infected with malaria will have symptoms of hot and cold. In many places in China, it is also known as "beating". There are more than 2 million cases of malaria every year in the world.
People die from malaria, and mosquitoes are the main culprit.
Therefore, mosquitoes are well-deserved to be called the ‘number one killer of mankind’, and it is very necessary for us to make ‘weapons’ to resist them.”
Two million people died!
Damn it.
The audience was all shocked when they heard this extremely exaggerated data. In modern society, there are actually diseases that can kill millions of people?
"Everyone who can watch my live broadcast is actually very lucky, because it means that you can still have a mobile phone, a computer, and a TV, and society can also provide you with a good network environment. These
These are things that many people cannot have or even see.”
"A good economic environment means superior sanitary conditions, but in many places in Africa, local people do not have such good conditions. I know an indigenous tribe who knows how to resist mosquitoes."
"In short, it is to smear mud all over the body, and use the smell and thickness of the mud to resist mosquito bites."
"In some very backward places, if this kind of soil is not available, some Africans will directly smear it with animal excrement. Although it has a certain effect, this method is unacceptable."
When Bi Fang said that he would rather smear feces to avoid mosquito bites, the audience fully understood the horror of mosquitoes.
This is a situation that has never been encountered in any previous adventures.
Only in the face of death can people let go of their shame and smear the dirtiest things.
"Why don't you look for some mosquito repellent herbs? With your ability, this is not a difficult task, right?" Leonardo was a little curious.
He has watched all of Bifang's live broadcasts, and as a Chinese, it is not difficult to find herbal remedies to repel mosquitoes.
Why do you have to apply mud?
It would be a shame to have such a good figure covered with mud.
【Yeah, why do you have to apply mud? 】
The audience is also very curious, is it not necessary?
"How long can you apply toilet water for?" Bi Fang did not answer directly, but turned to ask the audience.
【Um, how many hours?】
[I feel like I haven’t had it for a few hours...]
【It has no effect once you sweat.】
"Isn't this the reason?" Bi Fang laughed, "None of the commonly used products in modern industry can effectively repel mosquitoes. Sweating and moving will reduce the effect, let alone the mosquito repellent found in the forest. It is not
It’s useless, but it’s very limited, and it leaves a very noticeable odor on us.”
Ninety-nine percent of any substances that can be directly used in nature are inferior to industrial products.
It makes sense that human society has developed for so long.
It's not that the more primitive it is, the easier it is to use.
Using herbal medicine to repel mosquitoes is also very troublesome. You have to re-make it every once in a while, and you have to make tools to crush it to get the juice.
It is not as practical as applying a layer of mud. It is not only easier to find, but also more effective. One is chemical isolation and the other is physical isolation.
"There are no plants in Africa that can repel mosquitoes. People call them 'anti-mosquito trees.' Most local indigenous people in Africa choose to build houses near these trees or plants."
"But in addition, Africans still smear mud on their bodies, which can prove a lot of things. What we are looking for 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 ceramics factory, you will know that this is also a common pottery material."
"So this time we are not only looking for red mud, but also looking for water!"
