"Damn, hot water is useless to make ice! Mine also didn't work out! Where did the big guy who said he could run before? With less than forty hours to go, the disaster is about to begin, so what should I do? ”

"I said it didn't work a long time ago, it's better to go to the secret realm to find something that can generate electricity, and then try your luck to find an electric fan or air conditioner that hasn't broken yet."

"Upstairs is sick again, can we find this method? Hot water ice making buddy, see if there is a leak elsewhere, try it again, we didn't succeed in the hot water ice control method according to the big guy, but I have to say that the ancient method of the Tang Kingdom is really wonderful, and I can actually think of using the Joule Tomson effect. ”

"Joule Thomson effect? That's the case, when the gas passes through the porous material, there is an irreversible adiabatic expansion, and the temperature changes dramatically, right? ”

"Upstairs I asked the emperor yes, who took notes, I forgot the process of this so-called hot water ice-making method, is it too late to do the experiment now?"

"Reach out to the party, what to forget, just search it again, I tell you, is to make a small belly big bottle, and then decorate it with water, the bottom of the shelf is hot, and when the water in it is less and less, all of it is water vapor, quickly remove the fire source, and then find something more airtight, like a thicker cloth or the like to seal the mouth of the bottle, and then put it into a deep pit dug in advance, and you can see the ice after three days - what the big guy said before, not what I said."

"Ah, girl, the magic of the opens the door, the magic is home! Whoever wants to be able to make ice cubes, I'll capitalize a costume. ”

"Three days? After three days, I was rotten, and I didn't say anything, I just lay down and died. ”

"Brothers, I succeeded, there is no ice cube, there is still some ice ballast, this is the picture, everyone look at the picture, the real thing has disappeared." Big ice cubes .jpg'. ”

"I still think saltpeter ice is more reliable, but you have also seen that there are indeed people selling saltpeter now, but a piece costs 1 ton of water and a lot of food, why do I have a ton of water not to soak in it, and the food is not eaten for him? his grandmother. ”

"Yes, someone has successfully used saltpeter to make ice before, but there is too little saltpeter, is saltpeter in this other world a rare mineral? How do I remember having that thing in the latrine when I was a kid? ”

"We did extract a lot of saltpeter powder in the toilet, but the amount is too small, it seems that this road will not work, everyone, it seems that we will not be able to survive this disaster, it is estimated that 10% of the survival is good. Humanity is truly extinct! ”

"It's so unwilling, it's hard to get here, who would have thought ...... More than a dozen of us have died of heat stroke here, and it seems that this time it is really over! ”

"Tired, destroy."

"This doesn't work, that doesn't work, anyway, someone dies with me, and it's likely to be hundreds of millions, and I suddenly feel that it's worth it."

"Will Lin Yue not come out?"

"Yes, what about Lin Yue?"

"Where did Lin Yue go? What about Lin Yue? Why doesn't he care about us? Damn, this person is just too selfish, why doesn't he help us when he has the ability? Why didn't he give us his air conditioner? He deserves to die! ”

"Lin Yue should be damned!"

In the past few days, there have been people in the world channel who have been calling to follow some so-called bigwigs, and the legendary "hot water ice making method" that I don't know how to rely on is unreliable, and after failing one after another, when facing the current situation of disaster in just over a day, a mood called "despair" began to spread to the entire world channel.

While there are still those who insist on using hot water to make ice, they also know that this is extremely unlikely.

In the face of extreme heat, no one has a better way, and even if someone has, they don't want to share it with others, it's not that no one sells saltpeter, which is the most likely to make ice, but that kind of price also makes everyone prohibitive.

Even if someone gritted his teeth and went to buy it, he also found that there was only a limit to what he could do with a small unit of saltpeter.

At this moment.

The world channel is also gradually becoming less active.

Only a few people were still swiping the screen and cursing Lin Yue, but no one paid attention to them.

At this time, those who can still scold are also the first to be eliminated, because they will not do anything but scold.

"The one who is still scolding Lin Yue now must be a beggar, who hasn't been saved by Lin Yue last time? Besides, Lin Yue should save people, right? He has the ability to save billions of people, right, what the hell is the logic? Lin Yue didn't say anything this time, it seems that he has no choice, even if he is as strong as him, it is ...... it? What do I see? Let's go and see it! Lin Yue hung a lot of saltpeter! Moreover, each refuge village is limited to ten units, and the asking price only needs alloy or various waste electrical appliances and parts? Is he—Is he God? ”

Just when everyone was in despair because of the failure of the hot water ice making method, someone suddenly found that on the world trading channel, an extremely huge amount of saltpeter suddenly appeared!

And the one who hung the saltpeter was none other than Lin Yue whom they had just mentioned!

Lin Yue, the person ranked No. 1 in the world rankings, is also the person who shared the method of how to survive the disaster last time, and the person who was expected by countless people, and was also cursed and disgusted by countless beggars.

He, once again, before the catastrophe, appeared like a savior when almost everyone here was desperate and felt that they could only survive and see if luck could survive the disaster!

Saltpeter, ten units of saltpeter, is the most critical material for the earth-made ice process, almost close to half a ton.

And that's enough to make ice cubes that can survive any of the Vault Villages' lives!

"@所有人, everyone's attention. Lin Yue just sent us a piece of information, written a guide on how to survive this disaster, which will be free for everyone to use, you can judge for yourself whether it works according to your needs, and we have not deleted or rewritten any of the words. In addition, our refuge village has begun to be renovated, and we believe in Lin Yue! ”

And at the same time that the various refuge villages continued to quote the transactions of saltpeter issued by Lin Yue, the world channel had another message!

That was a message from Xing Lingfeng's refuge village, which ranked fourth in the global rankings!

"What? Lin Yue actually sent a way to survive the disaster? Does he really have a way? Ice making can only be said to be the first step, and giant hailstones and fire tornadoes can be followed! ”

"? Is it that simple? But...... It seems like it really can! Is Lin Yue a genius? How did you come up with this approach? Solve the doubts all at once, everyone hurry up and take a look, I think this disaster can pass! ”

"Wouldn't it be that easy? But it seems that as long as you make sure to survive the extreme heat with ice cubes, everyone can hide in an unsheltered basement and wait for the disaster to pass...... It seems like it's really possible. ”

"We've already started experimenting here, and someone has said before that the method of making ice from saltpeter seems to be feasible, but it's only been a few minutes, and the water is starting to get cold!"

"So is we! Lin Yue Niu Pi! ”

"Why not give it to individuals? I need it too! Is it discriminatory to survive alone? ”

"It's been more than a month, where did the solitary survivors come from, and now the solitary survivors are all regarded as beggars except for Lin Yue! Beggars,! ”

……

The survivors of the refuge village, who had just fallen into the abyss of despair, immediately began the experiment of saltpeter ice making after receiving Lin Yue's saltpeter one after another!

Although the saltpeter ice making method cannot produce that kind of huge ice block, the ice produced is enough to reduce the temperature in a small shelter by a lot, and it can also make the survivors gathered in the shelter no longer be bothered by the extreme heat, so as to basically solve the deadliest extreme heat disaster in this triple disaster!

The temperature in the room is constantly decreasing, and the hearts of the survivors are overflowing, as well as the heartfelt gratitude to Lin Yue, who has been behind the scenes!

Although there are still some curses in the world channel for why Lin Yue didn't come out earlier, everyone else has joined forces to scold, and everyone thinks that Lin Yue is the savior of this disaster!

……

Here, Lin Yue is constantly clicking on the transaction while constantly collecting the saltpeter ore mined by the robot dogs into the storage space.

Now, almost everyone has abandoned the idea of going to the secret realm to find power generation devices and air conditioners, and I don't know who is leading them, all of them are looking for ways to make ice, and this is what Lin Yue wants to see.

Regardless of whether it is useful or not, and regardless of the theorems or theories involved, the production time of those three days alone has completely failed in this regard.

What's more, if there is the slightest mistake in these three days, the cloth is not tightly covered, or the pit is not deep enough, or if something else is not done, the three days will be wasted.

After today, there are still 24 hours left tomorrow, where is the time to fail again?

Besides, the heat is already quite unbearable.

As for the saltpeter ice-making method, he didn't know how to make ice at all, but he had mentioned it in a similar documentary he had seen before.

However, he didn't know, it didn't mean that others didn't know, and after a little search of the world channel, he understood the general process of saltpeter ice making.

In short, find a large vat or something like a container with half of the water, then put the vat in a small pool, put saltpeter in the pool, and then put the water in the pool, and after a while the ice will be produced.

The principle is to take advantage of the fact that saltpeter will absorb a large amount of heat after dissolving in water, so that it can continuously cool the water, so as to finally obtain ice cubes.

If the amount is small, it can hold the room temperature down a lot, and if the amount is large, the ice cubes can be stored for a while, enough to survive the disaster.

When the group chat was lively, he did search for the sale of saltpeter in the World Trading Mall.

There really are, and there are quite a few.

But the asking price is more terrifying than the other.

A ton of water or something, hundreds of loaves of bread or something, or power generation equipment, or even all kinds of thermal weapons.

It's almost the same as the sand seller during the acid rain and flood, or even worse.

And it's not too small.

Among these people, Lin Yue felt that it was very likely that a considerable number of them were beggars who had struggled in this saltpeter mine, except for these people, who could have such a large amount of saltpeter?

After all, it hadn't been there before.

After letting Xiao Meng and the others go back first, Lin Yue built a small shelter in the saltpeter mine, installed a solar power generation package, and also installed an air conditioner.

Sitting in the center of the room in this underground shelter, Lin Yue lay on the sofa, and little by little he continued to exchange saltpeter for more various resources.

His rules of exchange are also simple.

It's a one-on-one exchange with the leader of the vault, and he won't pay attention to ordinary people's offers.

The World Trading Channel is actually constantly improving various functions, and Lin Yue soon discovered that it can now publish various exclusive transactions.

For example, the function of a separate transaction with the leader of the refuge village was something he hadn't paid attention to before.

He also immediately took advantage of this and issued an exclusive deal with the leaders of the refuge villages, using ten units of saltpeter to exchange for alloys or various waste electrical appliances or parts in the hands of these refuge villages.

The reason why he did not trade according to everyone was to prevent reselling, and second, he did not have so many saltpeter mines.

More than a dozen robot dogs are working around the clock, and the saltpeter mine that has been made here in the past two days is impossible to supply all the survivors.

Just after the systematic appraisal, he found that the ice that these ten units of saltpeter can make, that is, it can maintain the effect of more than 30 hours or so, Lin Yue felt that he had done his best, and he couldn't take care of too many people.

Five units is too little, and ten units is just right.

The total population of more than two billion people, as can be seen from the rankings before, the most is three or four hundred, the less is less than a hundred, take the middle number of 200 people, and remove those individual beggars, the total number of refuge villages in this world is far more than one million!

One million, ten units per refuge village, that's ten million units of saltpeter.

This astronomical amount, even if he is given another thousand robot dogs, he can't do it right away.

That's why he wrote in that deal that "the quantity is limited, and there is no guarantee of subsequent quantities, first-come, first-served".

At present, there are less than 40,000 units, and if you give the robot dogs a whole day, it will only be 20,000 units, and there can be no more.

As for what he got in exchange, Lin Yue really didn't demand it so much.

He has a lot of alloys, some of all kinds of parts, and a lot of parts can be obtained from waste electrical appliances, but these Lin Yue is not too demanding, just have it.

I guess I can still get a little bit of a shelter village.

In addition to saltpeter, Lin Yue also commissioned Xing Lingfeng to release the method of how to survive this disaster that he would think of. As long as the extreme heat problem is solved, giant hailstones and fire tornadoes are much simpler.

Of course, there is really no way to solve the saltpeter problem, and it is not completely impossible.

In the other world, except for a few terrains such as the wasteland, according to the illustration of the large regional map, other places do not seem to be bothered by water.

In addition to ice making, it is quite easy to soak in the water all day long in these areas with abundant water resources, and make a pool or something.

"That's all I can do, and the rest depends on the strong will of these people who have endured several disasters."

Lin Yue looked at the large number of alloys and various waste electrical appliances and parts that he had just taken out of the storage space all over the ground, and exhaled lightly.
