She only wants to do infrastructure construction

Chapter 44
However, everyone didn't know what Li Yewu was thinking. When they saw Li Yewu coming in, they arranged their clothes spontaneously, for fear of making the lady abrupt.

During this period, Si Ge showed Li Yewu various raw materials and blacksmithing tools in the factory, and also demonstrated the complete process of melting iron and iron.

In fact, the biggest difference between white iron and gray iron is that the carbon and silicon content of the material is different, and the other quenching processes are basically the same.

But there is another difference, white iron can be turned into gray iron, but gray iron cannot be turned into white iron.

To change its performance, the method is also very simple, as long as a certain proportion of carbon and silicon is added when smelting white iron, white iron can become gray iron with good toughness.

However, this method, like the discovery of gunpowder, is the result of an unintentional collision after hundreds of thousands of years of evolution.

When normal people smelt iron, at most they think about sacrificing themselves to the stove, but they don't think about adding chemical elements.

Of course, it was also because people did not know much about chemical elements during this period.

Even if carbon happens to be added, silicon cannot be added, because... silicon needs to be refined.

However, Li Yewu is an excellent student in chemistry, so it is not difficult for her to refine chemical elements.

It's just that there are no tools at hand, and there is no suitable venue.

Li Yewu was a little helpless. It seemed that she had to set up a chemistry laboratory before she could get serious about it.

Time is running out, and she can't allow her to measure whether the value is worth setting up a laboratory. At this time, she can only go through mountains and rivers.

Li Yewu rolled up his sleeves and drew a bunch of laboratory test tubes, and then told Zi Cui to go to the city to find similar things, and find a way to find someone to burn them if he couldn't buy them.

Zi Cui nodded without hesitation, and ran outside.

At this time, Li Yewu was not idle, and began to search for sand all over the ground.

Seeing this, everyone couldn't help but be puzzled: "What is the lady doing?"

"Make something small."

Li Yewu answered casually, but everyone couldn't help but shudder.

Well... so familiar lines...

They had heard from Erge that the little madam said to make something for her daughter's house, but the gunpowder came out and killed Long Er.

Now, the little lady said to make gadgets again...could it be... gunpowder again?
Could it be that the secret recipe for ironmaking mentioned by the little lady needs to use gunpowder! ! !

Everyone inexplicably felt the threat of death, and their throats were a little astringent.

"Ma'am... is your method of making iron reliable?"

Gunpowder explodes when it encounters an open flame, which is extremely dangerous. I have never heard of anyone using gunpowder to make iron. Even if they did, those people would all be dead...

The little madam is going to push everyone into the fire pit...

Everyone looked miserable.

Li Yewu didn't know what everyone was thinking, and he only thought that they had no idea, and comforted them patiently: "Don't worry, my method will try everything, and it will not fail."

"..." Everyone: I hope... Bodhisattva bless you!
However, who let himself sell his life to his master!Now the little madam not only saved the master, but also helped the master pay off the debts, and even got back all the land lost by the master!
With such kindness, what else can they do except die and accompany them!
Everyone can only join the ranks of looking for sand as if they were dead.

Although the Iron Smelting Bureau has a lot of iron materials, there is no sand and stone.

Li Yewu could only bring his idea to his palace again.

Fortunately, in addition to the hot springs, Shangwang Mansion also has a large training ground.

The training ground is covered with thick sand, one is to practice foot strength, and the other is to protect the feet from being hurt by the hard ground.

This is said to be one of Xiao Jiuxi's favorite places.

According to the description in the novel, although this person is in the second grade, he is very talented in learning Kung Fu, and he likes it himself, so he has his own martial arts training ground wherever he goes.

I usually like to go to the hot springs to take a bath after practicing.

Li Yewu didn't hesitate, and went directly to the training ground to dig sand.

Xiao Jiuxi won't be coming back anyway, so instead of wasting this place, it's better to make the best use of it for her.

Speaking of which, the earthen stove used to boil saltwater hadn't been dismantled last time. Li Yewu directed Sige and the others to carry the sand to the hot spring.

Everyone did not doubt that he was there, and cooperated to carry it over.

All the way through the corridor to the hot spring, everyone found a strange place.

The palace used to be just a barren house, but now there are no people there, and it is empty everywhere!

Brother Si couldn't help wondering where the others were going.

"They all went to work in the construction team, and they are happy to work for 200 yuan a day."

"..." Si Ge.

"But you don't have to worry. Helping me now is equivalent to helping the construction team. I will also count 200 yuan a day for you." Li Yewu smiled brightly.

"Uh... Wang... You don't have to give it to us, Madam, it's hard to come by, so you just keep it."

Si Ge waved his hands again and again.

They went out to work to help the palace, so how could they ask for money from the palace.

Li Yewu nodded movedly: "Okay, I won't treat you badly!"

Where did Xiao Jiuxi dig up these treasures? Look at the consciousness of these workers, they are really role models for our generation.

The reason why I have such emotion is because the group of people who went out to work also said so.

Li Yewu insisted on giving the money, so they handed it over to the old housekeeper consciously, saying that they would not suck the blood of the palace.

Li Yewu was so moved.

However, everyone didn't understand why the little lady was so moved because they were just doing their own thing.

As a dead soldier, life belongs to the master, let alone money, isn't it?
Ancient and modern thoughts are doomed to be unable to seek common ground, and the two sides started to get down to business after talking with each other for a while.

When it comes to the method of extracting silicon, it is actually simple.

Mix sand and coke, and the compound produced by high temperature heating is crude silicon.

Crude silicon plus chlorine gas can be heated at high temperature to obtain silicon tetraoxide, and then hydrogen can be changed to continue high temperature heating to obtain pure silicon.

This is the common sense of chemistry in middle and high school, as long as you listen carefully to the chemistry class, you will know the formula.

However, although the formula is simple, it is not easy to operate.

After all, there is no decent laboratory here, and the solid ones are okay, but it is more troublesome to collect gases such as hydrogen and chlorine.

However, things are dead and people are alive, so there are always more solutions than difficulties.

Li Yewu plans to make a batch of crude silicon first, use the crude silicon to test the properties of steel, and if it fails, then slowly purify it.

Anyway, Zicui's bottles and jars should not be so easy to find.

Thus, Li Yewu began to play house busy.

I saw that she heated the pot red, poured sand and coke into it continuously, and then covered it with a lid and simmered on high heat.

When everyone was worried that the iron pot was about to be burned, Li Yewu finally stopped adding firewood and happily opened the lid.

When the lid was opened, a miraculous scene appeared. These sands were fused with charcoal to form a strange medium. It was not like sand or carbon, and turned into strange stone particles.

Everyone was a bit speechless, the little lady was indeed a weird person, she actually played a game of mud cooking that children would play.

Seeing this, everyone was a little hesitant. Can this thing really train iron?
