Surviving in anime world, playing with a girl and getting watched by the live chat.

I don't know if it was because Dongyun's prayer worked, or if the system gave him a guaranteed reward since he hadn't gotten any good items before.

At that moment, the fire axe stopped on the lottery pointer.

"bingo!"

Chapter 103 Making Fire Axes and Salt

Fire axe.

Dongyun stared blankly at the fire axe in his hand.

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

Three weeks after the premiere of "Survival Wars," both Dongyun and his friends in this world, as well as viewers on Earth, know what it means to put a fire axe in the wilderness.

If the only dangerous animal roaming the edge of the bay's jungle is the leopard, they could kill it with this fire axe.

【Ohhhhhhhhhhhhhhhh!】

[Holy crap, a fire axe!]

[A miraculous tool has arrived!]

Bullfrog

Won the lottery? Let's absorb some of that good luck!

[What are you sucking for? Are you trying to survive in the wilderness? You want to end up sucking people dry?]

Finally, something good arrived, but unfortunately it's not a gun.

"Such a wonderful start! Cheers! Applause!"

Coming to his senses, Dongyun raised the heavy fire axe with delight.

He felt incredibly powerful right now!

"Hey Johnny, you're here!"

Pulling out the fire axe, Shinonome was so excited that he forgot himself and couldn't help but act out the role of the male lead in "The Shining".

Of course, he wasn't fully immersed in the role.

This can't be taken too seriously. If it is, Rin-chan will really become Rin-chan, and Xiao-jia will be chopped into mincemeat by him.

"I've seen The Shining. Please don't do this, it scares me."

Shima Rin tilted her head, unable to suppress a laugh.

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

In the wilderness, the sense of security that this axe brings can be just as good as, or sometimes even better than, that of a reliable companion.

"Wow! I haven't seen this before, what kind of meme is this?"

The appearance of the fire axe made Gabriel sigh in amazement.

Now, Shinonome is truly a terrifying upright ape. Even without a fire axe, he and Nadeshiko can kill a leopard. With a fire axe, she doesn't even dare to imagine what they can kill.

Could it kill a bear?

Although Gabriel often looks down on Shinonome and scolds him, she has great faith in Shinonome's abilities and Nadeshiko's strength.

"The Shining, a horror film."

Shinonome gave Gabriel a brief explanation of the story of The Shining with a smile.

With the fire axe, Dongyun's tree-cutting efficiency improved significantly. Compared to the difficult-to-use stone axe, the fire axe was incredibly easy to use.

He didn't quite understand why an audience member would throw a fire axe, but then he thought about it and realized that there were crossbows, guns, and even cannons in the pool, and even more outrageous things like cars and helicopters. A fire axe was just too ordinary compared to the other items.

That said, is it really possible to actually get some of these items through the draw?

RPG, armored vehicles, and armed helicopters.

You people are really good at throwing things away! Why don't you throw away warships or nuclear bombs? Don't you like them?

Not long after Shinonome chopped down the tree, Gabriel and Shima Rin prepared breakfast together. They also woke up Kagamihara Nadeshiko and told her not to sleep anymore, but to wait until after breakfast.

Kagamihara Nadeshiko's hand injury hadn't healed, so she couldn't do work like cutting down trees.

For other tasks that are not physically demanding, Gabriel and Shima Rin, who are quite close, are capable of doing them. It would be best if she could help, but it wouldn't be a big deal if she couldn't.

After finishing his meal, Dongyun went to cut down trees again.

With the fire axe in hand, he basically transformed into Bald Qiang, wreaking havoc on the small trees in the forest.

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

First, he had worked all day yesterday and was not very physically fit. Second, he was supposed to make sea salt, which he should have done yesterday, but he forgot about it.

Although forgetting is a bit far-fetched, his mind gradually went blank from repeatedly and mechanically chopping trees and making clay bricks, so forgetting is a normal thing.

When surviving in the wilderness, the methods for preparing sea salt are nothing more than sun-drying and boiling, or both. However, directly consuming sun-dried seawater or boiled inorganic salts will increase the burden on the kidneys, and in the long run, it will be harmful.

They are doing wilderness survival, not wilderness survival.

Whether the cruise ship belongs to this world is hard to say. If it does, there's no reason for the people on board to perish; they should know how to avoid the giant eyes in the sky. If it doesn't, then they can basically give up on the idea of ​​being rescued and should instead prepare for a long-term survival in this world.

To survive long-term, they cannot eat coarse salt for extended periods, as this is not much different from drinking seawater and would increase the burden on their kidneys.

Even the ancients wouldn't have made salt so crudely. Instead, they used the difference in solubility of inorganic salts in a saturated solution to create edible salt.

Dongyun didn't know how to make sea salt, but some people in the comments did. They said that coarse salt could be made into finer table salt using physical properties, minimizing its impact on their health. Even though the process was tedious, he had to do it.

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

"We need to make a filtration system."

Seeing the tutorials in the comments, Dongyun was somewhat troubled.

Since there were no plastic bottles, we had to use coconut shells.

There are bamboos in the jungle, and bamboo tubes would be perfect for making filtration devices, but the bamboo forest is too far away, and he and Nadeshiko cannot venture deeper into the jungle until their injuries have healed.

The tutorial in the comments section was to have him filter the seawater using a filtration device first.

Then, heat several seashells over a high flame to turn them into calcium oxide (CaO). After that, 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, a large amount of dried coconut shells are burned over a high fire. The ash from the dried coconut shells and some remaining wood ash are added to pure fresh water, stirred, and filtered through a filter to turn the filtered liquid into an aqueous solution of potassium carbonate (K2CO3).

The filtered seawater is also boiled or dried to make coarse salt. This coarse salt is then mixed with clean fresh water, and then prepared calcium hydroxide is added to remove sulfate ions (SO₂) and magnesium ions (Mg²⁺).

Equations: Mg²⁺ + 2OH⁻ = Mg(OH)₂ (precipitate); Ca²⁺ + SO₂⁻ = CaSO₄ (precipitate)

Then, an aqueous solution of potassium carbonate is added for further purification.

方程式：K2CO3+Ca(OH)2=2KOH+CaCO3（沉淀）

Finally, add some oranges to remove any remaining hydroxide ions from the liquid, then boil the mixture until it boils dry. This will give you edible sea salt. If you're worried about iodine deficiency, you can add some washed kelp.

During the production process, the comments section mentioned that quality control is also necessary to better remove impurities from the solution and produce better edible sea salt.

Otherwise, this kind of sea salt wouldn't taste bitter.

"Ugh, my head is so big, it's huge!"

Dongyun covered his head with both hands, feeling as if he had returned to his student days as he looked at the barrage of instructional comments.

His head was about to split open!

Chapter 104 Purity

Oh, I'm dying.

Dongyun covered his head with both hands, looking down in despair at the scrolling bullet comments in front of him.

Master, stop chanting, stop sending it, or his head will explode.

Is this a school activity? Why does making sea salt require so many steps? It involves not only chemistry but also math.

Unfortunately, even if Shinonome's head was about to explode, he still had to keep staring at these comments, learning and understanding their meaning bit by bit, and then making the salt.

This is a big project.

The average salinity of seawater on Earth is 35‰. Theoretically, 35g of salt can be extracted from 1L of seawater, but he would have to burn 10L of seawater to get less than 350g of sea salt.

This only produces coarse salt by boiling seawater. To obtain finer salt, one must also boil seashells and coconut shells, prepare various solutions, and add them to filtered seawater. Only after these tedious processes can one obtain edible sea salt without bitterness.

You need to boil at least 10 liters of water.

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

During the day, when they weren't using fire, they let the campfire smolder. Later at night, when they weren't tending the fire, it also smoldered, so their firewood wasn't consumed quickly. However, this was a different story when it came to boiling or frying salt.

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

The stoker shed is too small; it can't store enough firewood.

In addition, he also had to constantly fire the mud bricks for the house in the furnace, so their firewood consumption was particularly high.
