The big man has a living father

Chapter 103 Dust Explosion (23 words)

For Liu Ju, the research institute is like a fairy tale paradise.

Because when you get to the road, the most attractive thing that catches your eye is a huge windmill.

"Big windmill!"

Liu Ju went crazy! He jumped up and said, "Windmill! Windmill!"

"Sister, big windmill!"

Princess Wei Chang: "I saw it."

Huo Hai led the two of them inside.

As he got closer, Liu Ju looked up at the huge stone windmill and his hat almost fell off: "It... why isn't it spinning slowly?"

Huo Hai: "Because it is lubricated with oil."

Liu Ju looked at the big windmill in his hand, and then at the big stone tower windmill: "I want this! I want this!"

Huo Hai: "If you can take it away, feel free to do so."

The prince turned to look at the guard and said, "You, take it away."

The guard pointed at his nose: "Me?"

Liu Ju looked the guard up and down and shook his head: "That's too much."

"I'll get it when I grow up."

Huo Hai: "When you grow up, can you hold it?"

Liu Ju put his hands on his hips and said, "When I grow up and become the emperor, I can take it away."

Who instilled this ideology? How can this be allowed?
Huo Hai quickly corrected him: "That won't work. Even if it's your father, he has to pay for something. If others are unwilling to pay or offer tribute, they won't get it."

Liu Ju was stunned.

The guard behind: "Actually, kill that man..."

He was halfway through his words when he saw Princess Wei Chang glaring at him. If he continued talking, he would be killed, so he quietly shut his mouth.

When Liu Ju heard that even as an emperor he could not do whatever he wanted, he became confused. Wasn't this what Master Shi taught him?

Seeing that he could not take down the windmill, Liu Ju had no choice but to follow Huo Hai into it.

After entering, Princess Wei Chang saw the powder on the ground and asked: "Is this a mill? Why add a big windmill?"

Huo Hai: “The big windmill is used to provide power for grinding the mill.”

"This windmill has the same function as the waterwheel at the paper mill. When we were developing it, we made several different types of vehicles with different power sources, and finally we chose the waterwheel for use at the paper mill."

"This big windmill will stay here and be turned into a mill."

The stone mill was invented in the Spring and Autumn Period, but the novelty of windmill power still attracted the attention of Princess Wei Chang.

After entering here, Liu Ju quickly discovered a wooden pestle that was moving up and down.

Liu Ju didn't know it, but Princess Wei Chang knew: "This is for husking rice and wheat."

As for millet, it is too small to be husked by pounding, so it can only be husked with a stone mill.

Huo Hai took out a bag of wheat that had been dried in the sun: "Let's make flour."

There are three methods of shelling in this era, mainly water shelling, pounding shelling and crushing shelling.

These three methods were not invented by Huo Hai, but have become popular in Chang'an in the past decade or so.

This technology even existed thousands of years ago.

Maltose is produced when the wheat is soaked for husking but forgotten to be soaked, causing the wheat to germinate.

However, Huo Hai's equipment is obviously much more sophisticated.

The soaked and dried wheat is pounded lightly and then blown away with a windmill to remove the husks and grains.

Liu Ju, a windmill enthusiast, was in luck. He finally found a windmill that he could find guards to move back home. "This one, I want this one!"

"Okay." Huo Hai agreed. After all, this valley windmill can be made by anyone with hands, and it is not as expensive as a big windmill.

Hulled wheat is ground into flour using a stone mill.

Princess Wei Chang: "This big windmill has a stone mill attached to it, so it doesn't need to be moved by humans. It's quite convenient."

Huo Hai: "This windmill is too expensive to build. It is far less cost-effective than raising a donkey. Even if each village only builds one, it is still not cost-effective, mainly because it does not move when there is no wind."

Princess Wei Chang felt a little regretful.

Huo Hai took Liu Ju to sift flour with a metal sieve.

When the flour is sifted, the bran is sifted out.

Princess Wei Chang knew that the palace maids usually picked out the bran and millet one by one by hand. This metal wire sieve was more convenient than the bamboo sieve. "Is this gold wire?"

Huo Hai nodded: "One of the researchers used to make gold thread jade clothes. The gold thread he pulled was very thin, and I didn't want the gold thread jade clothes, so I used it to make a sieve."

"Now he is studying how to make other materials thinner."

Princess Wei Chang was puzzled: "Golden Jade Clothes."

Huo Hai: "Jade Box."

Princess Wei Chang understood and no longer wanted to eat the finished product.

All this was very new to Liu Ju, so he took it very seriously.

Princess Wei Chang asked, "What is the purpose of the courtyard next door, which is so heavily guarded?"

Huo Hai said casually: "Oh, the researcher inside used to be an alchemist, and now he is researching explosives."

Princess Wei Chang: "What is dynamite? What can it cure?"

Huo Hai raised his head: "It can cure all diseases, even the kind that can kill you."

What the hell, it can cure all diseases. Shouldn't it be called a cure only if it can completely cure the disease?

Huo Hai continued to explain: "After it is ignited, it will explode. The so-called explosion means that it will blow up and destroy anything nearby. At the center of the explosion, every small fragment that flies out is as powerful as a sledgehammer, and each piece reaches the highest temperature, and can tear apart anything within the explosion damage range in an instant."

Princess Wei Chang widened her eyes.

The guards were also stunned and hurriedly stood between Liu Ju and the next yard.

Seeing how flustered they were, Huo Hai raised his head and asked, "Why are you so excited?"

"If the amount of explosives they are researching can blow up the house and endanger us in the stone tower... then we have made a great contribution to the Han Dynasty. If such a powerful explosive is developed, it will be no problem to unify the world in ten years."

With this kind of explosive in hand, there is no need to worry about supplies or tactics. Just produce explosives directly and then push forward.

Huo Hai and Liu Ju were sifting flour, while Princess Wei Chang continued to observe the furnishings inside the stone mill.

After watching for a long time, Princess Wei Chang gradually felt something was wrong.

The stones of this stone mill are covered with marks of impact.

At first, Princess Wei Chang thought it was traces of carving with a knife or an axe.

Moreover, there were strong signs of blackening caused by burning on these stones, and Princess Wei Chang initially thought that they were traces of fire used to remove the stones.

After listening to Huo Hai's description of the explosion, Princess Wei Chang asked: "Has this stone mill been bombed?" Huo Hai nodded: "Yes."

The guards were anxious and hurriedly blocked Liu Ju from the next courtyard: "Your Highness, please leave quickly, it's dangerous!"

Huo Hai: "You are anxious again."

"I was the one who started the explosion at the stone mill. Can you please stop being so surprised?"

In order to demonstrate the explosion effect to a group of alchemists, Huo Hai created a dust explosion in the stone mill.

A group of alchemists understood after watching.

This is very similar to the thunder method that they have passed down through word of mouth!
It’s a pity that many books on alchemy were burned by Qin Shihuang, otherwise we would definitely have found a way.

A group of alchemists expressed regret.

Huo Hai didn't care about these. He knew the formula of ordinary gunpowder. He asked them to experiment on their own just to cultivate the habit of recording experiments and experiment with various materials they were familiar with.

Perhaps there will be additional discoveries.

A large group of alchemists started to do something with a purpose, and they recorded it and communicated with each other.

Researching explosives is not a difficult task, it just takes time.

After hearing the new term "dust explosion", Princess Wei Chang inquired carefully with Huo Hai, only to find out that the mill could be so dangerous.

Huo Hai: "There is no open flame here. Unless there is static electricity, there will be no danger of explosion."

Another new term. Princess Wei Chang asked about the static electricity.

Huo Hai described what static electricity is.

Static electricity is something that ordinary civilians would never encounter. However, Princess Wei Chang, who uses a lot of animal skins for heating and often touches metal objects, has experienced it.

After hearing the description, Princess Wei Chang stared at the guards and asked, "Are you wearing sweaters?"

Guard: "Your Highness, of course I am wearing it. It is so cold, who can stand it without it?"

I could wear a hard top in the past, but now I have woolen sweaters. It would be a shame not to wear it. Wouldn’t it be asking for trouble if I didn’t wear it?
Princess Wei Chang looked at Liu Ju who was sifting flour nearby, and then looked at the knives and woolen sweaters on the guards: "You go out first!"

After sending people out, Princess Wei Chang was still afraid.

Dust can actually explode!
Static electricity can actually cause an explosion.

Princess Wei Chang looked around at the others to see if anyone still had metal on them.

There is no need to look at this woolen sweater, everyone wears it.

So far this winter, the ranch has been operating at full capacity and has produced 300,000 woolen sweaters without freezing the sheep to death.

Except for 30,000 pieces left for the miners' families living on the ranch, the rest have already flowed into the market.

Almost every poor person in Chang'an City owned one.

Although woolen sweaters were relatively cheap when they first came out, giving people the impression that they were common people's clothing, this impression did not last long, because many people in the court noticed that Liu Che had already been wearing woolen sweaters.

So they also started buying woolen sweaters to wear, and when they put them on, they found that, hey, they are really warm!

Even if I wear a woolen sweater inside and do a little physical labor, I still feel hot!

Hot fever!

Therefore, the wealthier nobles had more than one each.

Instead, the middle-class people in Chang'an City were slow to react and did not have time to buy.

When they wanted to buy it, it was out of stock on the market.

Therefore, the maids under the princess all wore woolen clothes.

However, no one was carrying any metal accessories, so Princess Wei Chang then remembered that wearing hairpins was the privilege of the Queen and the eldest princess.

Although there are some people who secretly overstep their authority among the people.

But none of his subordinates dared to overstep their authority.

Thinking of this, the princess remembered that she had a hairpin in her hair and hurried out: "I'll go out and wait for you!"

Huo Hai led Liu Ju to sift some more flour. Liu Ju said, "It's really fun! I want to play with the windmill!"

Huo Hai: "Go back and play with His Majesty. We still have other things to play with."

However, Liu Ju still remembered that he wanted a grain windmill, so Huo Hai asked someone to prepare a grain windmill for Liu Ju.

After leaving the stone mill, Huo Hai and Liu Ju walked on the road in a swagger and continued to move forward.

But in Princess Wei Chang's eyes, the research institute has changed.

At a glance, explosions could be seen in every yard.

The key point is that the explosion that Princess Wei Chang imagined did not have fire or smoke, but she directly imagined a scene of things being shattered.

The more you look around, the more dangerous it becomes.

Huo Hai didn't care at all and took Liu Ju into a new courtyard: "This is specially for you, the prince, to research new flavors of milk."

Besides the windmill, Liu Ju likes to drink milk, although he drinks it slowly: "Really?!"

After Huo Hai brought Liu Ju in, Liu Ju went crazy.

At this time, there were several people in blue coats in the courtyard, and one of them was driving a horse.

And several others were recording data.

In the middle of the main hall of the courtyard is a strange windmill.

Like an umbrella.

At this moment, it is spinning wildly!

To Liu Ju, isn't this just a windmill spinning extremely fast? !

Liu Ju was crazy about this rotating wheel-shaped thing: "Windmill, windmill! Iron windmill!"

Huo Hai: "This is not a windmill, this is a centrifuge."

Huo Hai looked at the researcher next to him: "How long has this been going on?"

The researcher cupped his hands and said, "Sir, this batch has almost been separated."

This centrifuge is used to separate milk and cream.

After being centrifuged, the upper layer is cream and the lower layer is skimmed milk.

Because the demand for oil and fat at the research institute has been particularly high recently, Huo Hai taught the centrifuge degreasing method.

After all, pasture milk production is very high.

Huo Hai chuckled: "Your Highness, with the flour from which the bran has been removed and the butter from which the fat has been skimmed, we can make delicious food."

Huo Hai had wanted to eat it for a long time, but it was too troublesome and he was too lazy to move, nor was he too lazy to teach the chef.

I’m finally going to eat it today!
