Survival in the second dimension, bringing a girl and being watched by barrage

Kagamihara Nadeshiko went into the tent and said with a little disgust when she smelled the sour smell of sweat in the tent.

“Red bean paste Smi Masai.”

Shinonome lazily apologized.

He has been speaking Chinese all the time. Perhaps it was because the system had a built-in translation system. He could understand the Japanese spoken by the girls, and the girls could understand his Chinese.

Not only he can understand it, but the audience can understand it too.

However, after he speaks Japanese, it is impossible for the system to translate his Japanese back into Japanese.

Therefore, what Kagamihara Nadeshiko heard was his authentic Chinese-style Japanese, which made the girl couldn't help laughing.

"Xiaoyun, your accent is so funny. Sorry, I don't mean to make fun of you, but it's really funny."

To Kakamigahara Nadeshiko, Shinonome's Japanese with a strange accent did sound strange.

Well, that's normal. He doesn't know Japanese. Although he has watched a lot of Japanese comics, he learned most of his Japanese from anti-Japanese TV dramas. Even from action movies, the only thing he can remember is the classic line "Yametie".

Dongyun was very tired, extremely tired.

After the food in his stomach was slightly digested, he fell asleep while chatting with Nadeshiko.

As for the problem of feeling sour and smelly all over, let's talk about it tomorrow. Anyway, no one has taken a shower in the past two days, so they all feel sour and smelly. You'll get used to it after smelling it for a while.

The next day.

Dongyun got up much later than usual.

When he woke up, Gabriel and Shima Rin were no longer in the tent.

He immediately got out of the tent and was relieved to see Shima Rin and Gabriel in the camp. Although it was unlikely, he was worried that Shima Rin and Gabriel would leave the tent and disappear at night.

"Let's draw a prize first."

As usual, the first thing Dongyun does when he wakes up is to draw a lottery.

As always, with anticipation but not much expectation, he clicked on the draw.

Just like the unboxing scene of CS:GO appeared in his eyes, and all kinds of things flashed before his eyes. Most of them were erasers, followed by tissues, pencils, keys, meal cards and other useless things.

Please don’t use the eraser anymore, or he will really have to complete a chess set.

After a while, the prop that had been moving backwards was about to stop.

"!!!"

Dongyun saw the fire axe.

Oh my god, oh my god, oh my god! Stop, stop, stop, stop here, don't slide, don't slide, don't slide!

Even when he opened a box in "CS:GO", he was not so excited to see gold coming out of the box. This is a fire axe that can chop down trees, animals, and even cruise ship doors!

I don’t know if Dongyun’s prayers worked, or if he didn’t get any good stuff before, so the system gave him a guaranteed reward.

At this moment, the fire axe stopped on the pointer of the draw.

"bingo!"

Chapter 103 Fire Axe and Salt Making

Fire axe.

Dong Yun stared at the fire axe in his hand in a daze.

Gabriel and Shima Rin also looked over after hearing "hit", and were dumbfounded when they saw the fire axe in his hand.

"Survival War" has been on the air for three weeks. Whether it is Dongyun and others who are born in this world, or the audience far away on Earth, they all know what it means to put this fire axe in the wilderness.

If the only dangerous animals on the edge of the jungle in the bay were leopards, they could kill them all with this fire axe.

【Ohhhhhhhhhhhhhhhhhh! 】

[Oh my god, fire axe! ]

[The artifact is coming! 】

【Bullfrog】

【Won a big prize? Take some luck】

[What are you sucking for? You are trying to survive in the wilderness. You want to be sucked to death and then you want to end it, right?]

[Finally, something good has arrived, but it’s not a gun]

“Such a wonderful start, please cheer for me, please cheer for me!”

Coming back to his senses, Dong Yun raised the heavy fire axe in joy.

He felt that he was terribly strong now!

"Hey, Johnny, here we come!"

Pulling out the fire axe, Dong Yun was so excited that he forgot himself and couldn't help but play the role of the male protagonist in "The Shining".

Of course, he wasn't completely into the role.

He can't get into the role. If he does, Rin-chan will really become Rin-chan, and Xiaojia will be chopped into pieces by him.

"I've seen The Shining. Don't do this. I'm scared."

Shima Rin tilted his head and couldn't help laughing.

Seeing the fire axe in Dongyun's hand, her mood also improved.

The sense of security that this axe brings in the wilderness is completely comparable to that of a reliable companion, and sometimes even surpasses that of a companion.

"Wow! I haven't seen this before, what's the point of this?"

The appearance of the fire axe made Gabriel couldn't help but sigh.

Now Dongyun is really a terrifying upright ape. Without the fire axe, he and Fuzi can kill the leopard. With the fire axe, she dare not imagine what he and Fuzi can kill.

Can't it kill a bear?

Although Gabriel often despises Shinonome and scolds him, she believes in Shinonome's abilities and Nadeshiko's strength.

“The Shining, a horror movie.”

Dongyun smiled and briefly explained the story of "The Shining" to Gabriel.

With the fire axe, Dongyun's tree-cutting efficiency has greatly improved. Compared with the difficult-to-use stone axe, the fire axe is much easier to use.

He didn't quite understand why an audience member threw a fire axe, but then he thought, there were crossbows, guns, and even cannons in the package pool. What's more outrageous is that there were cars and helicopters. A fire axe was just too ordinary compared to the previous things.

By the way, can some of the things here really be drawn?

RPGs, armored vehicles, attack helicopters.

You guys are really good at throwing things. Why don’t you throw battleships and nuclear bombs? Don’t you like it?

Dongyun had not been chopping trees for long when Gabriel and Shima Rin prepared breakfast together. They also woke up Kagamihara Nadeshiko and told her not to sleep anymore and to wait until she had breakfast before going to bed.

Kamihara Nadeshiko's hand injury has not healed yet, so she can't do work like cutting down trees.

The rest of the work is not strenuous and can be done by Gabriel and Shima Rin, who is almost as good as her. It would be best if she can help, but it is no big deal if she can't.

After dinner, Dongyun went to chop trees again.

With the fire axe, he basically turned into Baldy Wang and started killing the small trees in the forest.

However, he didn't chop trees for too long today.

Firstly, he had worked all day yesterday and was not very tired. Secondly, he had to make sea salt, which he should have done yesterday but he forgot about it.

Although it was a bit outrageous that he forgot, his brain gradually became empty as he repeatedly chopped trees and burned bricks mechanically. It was normal for him to forget.

When surviving in the wilderness, the methods of preparing sea salt are nothing more than drying and frying, or both. Simply consuming dried seawater or boiled inorganic salts will increase the burden on the kidneys and will be harmful in the long run.

They are surviving in the wild, not trying to survive in the wild.

It's hard to say whether the cruise ship is from this world. If it is, there is no reason for the people on the ship to be in trouble. They should know how to avoid the big eyeball in the sky. If not, then they can basically give up the idea of ​​being rescued and honestly prepare to survive in this world for a long time.

If they want to survive for a long time, they cannot eat coarse salt for a long time. This is not much different from drinking sea water and will increase the burden on the kidneys.

Even the ancients would not make salt in such a crude way. Instead, they used the different solubility of inorganic salts in saturated solutions to make edible salt.

Dongyun didn't know how to make sea salt, but someone in the barrage knew that using the physical properties of coarse salt could be made into finer table salt, which could minimize the impact on their health. Even though the process was cumbersome, he had to do it.

Even if they board the cruise ship, they will use up all the salt on the cruise ship, and they will still have to make sea salt in the end.

“We need to make a filtering device.”

Dongyun felt a little distressed when he saw the teaching of Danmu.

Without plastic bottles, I can only use coconut shells.

There are bamboos in the jungle, and bamboo tubes are very suitable for making filtering devices, but the bamboo forest is too far away, and they cannot go deeper into the jungle before he and Fuzi's injuries are healed.

The teaching method of Danmu is to let him filter the sea water with a filtering device first.

Then burn a few shells over high heat to turn them into calcium oxide (CaO), then put them in a container and add fresh water to turn them into an aqueous solution of calcium hydroxide.

That is, CaO + H2O = Ca(OH)2

Then use a high fire to burn a large amount of dry coconut shells, add the dry coconut shell ashes and some remaining wood ash into pure fresh water, stir, and filter with a filtering device to turn the filtered liquid into an aqueous solution of potassium carbonate (K2CO3).

The filtered seawater is also burned or dried to make crude salt, which is then put into fresh water and mixed with clean fresh water. Then, prepared calcium hydroxide is added to remove sulfate ions (SO?2?) and magnesium ions (Mg2+).

Equation: Mg2+ +2OH- =Mg(OH)2(precipitate); Ca2+ + SO?2? = CaSO4(precipitate)

Then add an aqueous solution of potassium carbonate for new purification.

方程式：K2CO3+Ca(OH)2=2KOH+CaCO3（沉淀）

Finally, add some oranges to remove a little bit of hydroxide ions in the liquid, and then boil the mixed solution dry. What you get is edible sea salt. If you are worried about iodine deficiency, you can add washed kelp.

During the production process, the barrage said that the quality must be judged and controlled, so that impurities in the solution can be better removed and better edible sea salt can be made.

Otherwise, this kind of sea salt will not taste bitter.

"Oh, the head is so big!"

Dongyun covered his head with his hands and looked at the barrage of teaching videos, feeling like he was back in his student days.

His head is about to split open!

Chapter 104: Purity

Oh, I'm dying.

Dong Yun covered his head with his hands and looked down in despair at the scrolling barrage in front of him.

Master, please stop chanting and sending messages. If you continue sending messages his head will explode.

Are you in school? Why does it take so many steps to make sea salt? Not only does it require chemistry, but also mathematics.

Unfortunately, even if Dongyun's head was about to explode, he still had to stare at these barrages, learn little by little, understand their meaning, and then make the salt.

This is a big project.

The average salt content of seawater on Earth is 35‰. Theoretically, 1L of seawater can extract 35g of salt, but he has to boil 10L of seawater to get less than 350g of sea salt.

This is just crude salt obtained by burning seawater. If he wants to get finer salt, he has to burn shells and coconut shells, mix various solutions, and add them to the filtered seawater. Only after tedious operations can he get edible sea salt without bitterness.

At least 10L of water should be boiled.

Dongyun rubbed his head, wondering how much firewood it would take to make salt.

During the day when they don't use the fire, they let it smolder. In the late night when they don't watch the fire, the campfire also smolders, so their firewood consumption rate is not fast, but it is hard to say if it is used to cook and fry salt.

Because of the rain in the previous two days, all the firewood they had stored in the fire shed had been used up. If he wanted to make sea salt, he would have to go collect and chop wood.

The fire shed is too small and can’t store much firewood.

In addition, he had to use the furnace to continuously burn earthen bricks for the house, so their firewood consumption was particularly high.
