"Mud?" Leonardo repeated it hesitantly.

What kind of operation is mud, is it not to make a fire, and then burn the soil into pottery?

Finally brittle to use sharp shards as weapons?

Leonardo thought about the broken porcelain at home, it was indeed sharp......

[Who said before that the next step was to make weapons, the prophet knife]

[Is it a stone spear?] 】

[Didn't you hear Fang Shen say that he wanted to make ironware before he came? Open the furnace directly to make iron! 】

Bi Fang didn't reply, his nose fluttered, he sniffed lightly in the air, and was happy: "How much insect repellent water have you applied, the smell is choking." ”

Leonardo was a little embarrassed: "No way, there are too many mosquitoes here." ”

He suspected that if he was completely like Bi Fang, wearing no clothes and no insect repellent, he would probably be sucked to death by mosquitoes if he stopped.

Even when he was sitting on the ground knitting shoes just now, Bi Fang was knitting while repelling mosquitoes.

If it weren't for that, the shoes would have been made a little faster.

[I remember Fang Shen said a long time ago that if you look for a water source, you can look at animals and insects, and if you go to a place where there are many mosquitoes, you can often find a river]

[Yes, I also remember this, it seems that I said it when I was in Qinling]

[The ones in front are all old fans]

"That's right, the larvae of mosquitoes are completely aquatic, so as long as there is a small stagnant water, like a small flower pot on a balcony, it can multiply in large numbers."

An adult female mosquito lays eggs in stagnant water, can lay more than 300 eggs at a time, and can reproduce as long as you leave it alone and keep the container with water.

The eggs hatch into larvae after 24-48 hours in the water, and after another 10 days, the mosquitoes will develop into adults, and then begin to feed shortly after.

It can be called savage growth.

Not to mention in the rainforest, where the water is so rich that you don't even need puddles, you don't need damp soil.

[I've always hated mosquitoes!] 】

How could God have created such a demonic creature? 】

[In order to fill the vacancy of no mosquitoes in my country in winter, a scientist finally developed a cold-resistant mosquito]

[I've seen this news, I should pull it down and cook it!] 】

[Get my piece of the pie!] 】

[In fact, after filling the vacancy, there will be a lot of extra food, which will help animals survive the cold winter, which is very beneficial to ecological protection...... I can't make it up]

"It's because there are so many mosquitoes that we have to make weapons to defend against them." Bi Fang, who put on his shoes, waved his hand and motioned for Leonardo to follow.

At the same time, I looked around, and I found a broken branch.

Remove all the extra branches, and a nice stick appears.

"Because there are so many mimics in the rainforest, and the dark environment is easy to get used to, a good stick is especially important at this time, it can help us 'scare the snakes'."

"You can also prepare one, after all, our routes don't coincide exactly." Bi Fang looked at Leonardo behind him and suggested seriously.

Leonardo smiled, turned his head to look around, and learned to pick one up, but it was not as straight as Bi Fang's, and the appearance was a little worse.

[Lalala, late but arriving]

[I know, I know! 】

[You can always trust a straight stick!] 】

[If you get lost in the rainforest, don't worry, calm down, find a straight wooden stick as a weapon first!] 】

[You've got the artifact, go find a beast and try it!] 】

"Where did I just go?" picked up the stick, and was interrupted by netizens again, Bi Fang forgot where he was talking about.

"Mosquitoes, you said you were going to use dirt to make weapons against mosquitoes." Leonardo added.

Linked to the dirt that Bi Fang said, Leonardo had already vaguely guessed something.

Leonardo was not uninformed, he had met many different people on his travels, even in Africa: "Are you going to paint mud? ”

Bi Fang raised his eyebrows and did not deny it: "You have been to Africa? ”

Leonardo nodded: "I've made movies where before, I've seen the locals do this, and to be honest, I think it's quite primitive, they even use mud for bathing." ”

Bi Fang was noncommittal, but netizens scratched their heads, feeling that they couldn't understand this alien exchange.

Mosquitoes, Dirt, Africa?

What the hell.

"Do you know what is the deadliest animal in the world?" Bi Fang did not answer directly, but asked the audience.

What is it?

Before the audience could react, Bi Fang had already given an example to himself: "Great white shark? Lion? Tiger? Or a viper? Poisonous spiders? Actually, it's neither, it's always mosquitoes that kill the most. ”

Mosquito?

The audience was stunned, but many people reacted.

Disease!

That's right, no creature transmits disease better than mosquitoes!

"There are a lot of things that you may not understand, but in fact, the website 'Life Sciences' has ranked the 10 deadliest animals in the world, and they pose the greatest threat to human life.

Amazingly, the world's deadliest animals are not crocodiles, great white sharks and African lions, but inconspicuous mosquitoes.

Unexpectedly, the most dangerous animal in the world is actually mosquitoes. There are currently different species of mosquitoes everywhere on the planet except Antarctica. Most of the time, a mosquito bite just tickles you, but some mosquitoes carry the malaria parasite. It is a parasitic disease in which the pathogen is called Plasmodium.

After entering the human body, the parasite will parasitize in the red blood cells in the human body, and people infected with malaria will have symptoms of hot and cold, which is also called 'pendulum' in many places in China. Mosquitoes are the main culprit in the more than 2 million deaths of malaria in the world every year.

Therefore, mosquitoes are deservedly called "the number one killer of mankind", and it is very necessary for us to make "weapons" to defend against it. ”

Two million dead!

the groove.

Hearing this extremely exaggerated data, the audience was all taken aback, how can there be diseases in modern society that can cause millions of deaths?

"Now all the people who can see my live broadcast are actually very lucky, because it means that you can still have a mobile phone, a computer, a TV, and the society can still provide you with a good network environment, which is something that many people can't have, or even see."

"A good economic environment is a good sanitation environment, but in many parts of Africa, the local people do not have such good conditions, and I know an indigenous tribe that knows how to resist mosquitoes."

"In short, it's to apply mud, cover your whole body with mud, and use the smell and thickness of the earth to resist mosquito bites."

"In some very backward places, if even this soil height is not available, then some Africans will directly use animal feces to smear it, although it has some effect, but this method is unacceptable."

When they heard Bi Fang say that they would rather smear feces to avoid mosquito bites, the audience completely understood the horror of mosquitoes.

This is something that has not been encountered in any adventure before.

Only in the face of death can one let go of shame and smear the dirtiest things.

"Why not look for some mosquito repellent herbs? With your abilities, it's not that difficult, is it? Leonardo was a little curious.

He has watched all of Bi Fang's live broadcasts, and as a Chinese person, it is not difficult to find herbs to repel mosquitoes.

Why do you have to smear mud?

It's a pity to paint mud on such a good figure.

[yes, why do you have to smear mud?] 】

The audience is also curious, there is no need for this, right?

"How long do you care about the toilet water?" Bi Fang did not answer directly, but turned his head to ask the audience.

[Uh, how many hours? 】

[I feel like I haven't ....... for a few hours]

[As soon as you sweat, it has no effect.] 】

"Isn't that why?" Bi Fang smiled, "The commonly used products of modern industry cannot effectively repel mosquitoes, sweating, moving, will reduce the effect, not to mention the mosquito repellent found in the forest, it is not useless, but it is very limited, and it will leave a very obvious smell on our body." ”

Ninety-nine percent of any substance that can be used directly in nature is inferior to an industrial product.

It makes sense that human society has developed for so long.

Not the more primitive the better.

It is also very troublesome to use herbs to repel mosquitoes, and you have to re-do it every once in a while, and you have to make tools to mash it to get the juice.

It is not only easier to find, but also more effective, one is chemical isolation, and the other is physical isolation.

"It's not like there are no plants in Africa that have a mosquito repellent effect, and people will call them 'mosquito trees'. Most of the indigenous people in Africa choose to build houses near these trees or plants. ”

"But in addition to that, Africans still put mud on their bodies, and this proves a lot of things, and now what we are looking for is this mud, red mud."

"Red mud, also red mud in the literal sense of the word, is mainly composed of laterite, a terrestrial material carried by rivers. Rich in iron oxide, if anyone has worked in a ceramic factory, they will know, this is also a common pottery material. ”

"So this time, we are looking for red mud and water!"
