People who can make ice cubes directly in the summer will not feel amazing in the future as long as there are materials to make them, and this is the inheritance of culture and the openness of thought.

But in this era, it is estimated that many people will be regarded as demons.

Of course, this demon is not that kind of demon, but a demon who can do witchcraft, and will make people scared and frightened.

A literati once said that the gods called everything that they could not control as demons.

And for people nowadays, people who will be beyond their comprehension are called demons.

Zhang Jiao, the original leader of the Yellow Turban Thieves, was called a demon, not because of his ability to make people into Yellow Turban Hercules, but because he was beyond the control of the imperial court, because he was attacking the imperial court.

Therefore, it will naturally be called the demon road by the imperial court, and the qi of the Han Dynasty has not yet been exhausted, and the court that has ruled the world for so many years.

After experiencing so many emperors and so much glory, the people today call themselves Han people.

Even after all these years, it is still like this.

Therefore, Zhang Jiao is destroying the happy life of the people, even if most of the people under his command are farmers, ordinary people, those who are basically hopeless for life, and are oppressed by officials.

But there are already many people who call Zhang Jiao a demon, because even if life can't go on, they are still alive, still living humbly, and it's better to live than to die.

Not many people like war, except for those who have war in their blood and love war, and those who want to live a peaceful life even if they have a bad life.

Chu Feng didn't want to be regarded as a demon, let alone let this seemingly very scientific method of making ice cubes be regarded as a demon.

Saltpeter, also known as flame nitrate, potassium saltpeter, etc., has a high practical value, but unfortunately, at this time, most people don't know what this thing is, and they don't know what it is for.

It was not until the Song Dynasty that some people used saltpeter to make ice.

If Chu Feng wants saltpeter, he must inquire in many ways and find it in person, after all, this is not in the future life, and it can be bought with money.

In this situation, even if you have money, you can't buy a lot of things.

Fortunately, saltpeter can be obtained without extraction, and it is a raw material that exists in nature.

With money, you can let people look for it, as long as it is on the surface, or some white particles that appear on some earthen houses, Chu Feng will let people collect them, and then verify them one by one.

In the end, he finally found a way, and then he wanted to cover it up and use it to fool the past, so that others didn't know what he was doing.

Once you have saltpeter, you can make ice.

Saltpeter can be used repeatedly, but after dissolving in water, the extraction method is more troublesome.

Chu Feng went directly into his cellar and asked others to carry some water into it, and began to secretly make ice cubes, and then pretended that the water was frozen into ice cubes by the cellar.

In fact, he made it himself, but it was made more secretly, and ordinary people did not find it, and there was no manufacturing of it.

The Zhen family's ice cubes were not enough, so Chu Feng had to donate generously and take out the ice cubes he had saved.

At this time, Chu Feng missed the air conditioning of later generations very much, and the days when there was air conditioning were called a comfort.

Blowing the air conditioner, then lying on the sofa, playing with the mobile phone, thirsty, you can also eat watermelon.

Speaking of watermelons, in fact, there are also watermelons in this era, but because of the drought, all the watermelons produced this summer have been reduced.

Now it's a situation where a glass of water is precious, because most of the river has dried up.

Lying on top of the chaise longue with ice cubes underneath, a hint of cool air drove away some of the stuffiness.

However, because the weather was too dry, the ice cubes melted after a while, and they couldn't be looked at to make ice cubes.

Chu Feng felt that this summer was the most difficult summer to survive, and it seemed that he would need to hide some ice cubes in the winter in the future.

I didn't have this kind of thinking before, because the summer was not very hot, and because I was used to the air-conditioned life in the future, I didn't realize this problem.

This summer, it can be regarded as a lesson for Chu Feng.

In the face of drought in most parts of the Central Plains, there was still some small friction on the border between the princes, but now there is no friction.

Everyone looked across the city, sighed at each other, shook their heads, and had no intention of fighting at all.

On such a hot day, who wants to fight, with such a big sun, weapons are hot.

They all have to face the situation that there is no food to eat, no water to drink, people are going to die of thirst, and they have to fight, and they don't have to worry about a bad one and a direct mutiny.

Therefore, it is mainly a soft policy, you don't beat me, I won't beat you, and we have survived this sad drought period together.

Cao Cao's Yanzhou has begun to lack grain, even if it is not enough to open a warehouse to release grain, and it is impossible to release all the grain, because there is still a winter to be overcome, and now all the grain is eaten, and when it comes to winter, there is no food left.

If it was the original Yanzhou, it might still be able to maintain and maintain, but now Yanzhou, after accommodating a lot of displaced people, food has become tight.

As the lord of Yanzhou, Cao Cao had to think of getting food, and in the end he could only go to Yuan Shao.

"This porridge is all dry, I used to drink porridge, most of it was water, only a little bit of rice, but now it's good, there is more rice, but there is less water, alas, God, you can do it, let it rain a little."

"Yes, if it doesn't rain in the summer, how can we live, but we will be thirsty to death."

"Alas, if there is a great drought today, this is someone who has angered God!"

Because there is a drought in most places, some people are cranky, and they always think that someone has angered God to do this.

But they don't want to think about it, the world is so big, some people do evil, but there are also people who do good.

Will the guilt of this evildoer make God angry, and then directly drought and punish the people?

Then, those who do good deeds have not suffered with them, and most of the people have made a living from planting, and they have not done much evil in this life, but they have done a lot of good deeds, why should they suffer such pain?

It's all because of ignorance, because of the fear in my heart, always thinking about finding an excuse to be at ease, always thinking about explaining everything with my own thoughts.

This is also why Chu Feng did not dare to put forward the idea of making ice cubes from saltpeter at this time, not to mention whether Cao Cao could accept it.

Let's just say that those who like to think crankily and like to tell right and wrong the most, they will not let go of this opportunity to make themselves feel at ease.
