These old fritters are not the same as the clear, stupid and die-hard retinue in the palace.

They can become monopolies in this chaotic Taiqi Prefecture, and there must be intricate forces behind them.

For them, Li Yewu will not be gullible, it is almost the same to be polite on the surface, and he doesn't expect them to do anything anyway.

Therefore, Li Yewu did not frown when answering the question, and directly released the smoke bomb without blushing or panting.

However, her words were casual and sincere, and the head of the Xu family could not find anything wrong, he was worried that asking a few more words would arouse Li Yewu's vigilance, so he could only be vague.

"I thought the princess wanted so many jars because she was in a hurry, but it turned out to be a false alarm. If the princess has a small place, you must say that although the small ability is limited, she will never refuse. ”

"The master of the Xu family has a heart, if I really have difficulties in the future, I will definitely look for you, and please don't be stingy with advice when the time comes."

"Uh...... Where is the princess, this is as it should be, as it should be. ”

It was late at night, and the head of the Xu family and a group of men put down their things and didn't stay long, and left quickly.

It wasn't until they walked away that Li Yewu opened the box to check.

Zicui did help find a lot of things, but it was really just a matter of her pictures.

She asked for glass test tubes, but Zicui only found small jars of pills or toilet rouge, and larger jars of various pickles.

Zicui bought a lot of things, several large boxes.

However, she herself was not very happy, and only frustrated.

"Madam, Zicui has done her best."

The little lady finally gave her a task, but unfortunately she couldn't complete it well.

Li Yewu saw her blame herself: "The things I want are so tricky, it's already very powerful that you can help me find similar ones, I dare to say that you are not as careful as you are to change anyone!" ”

"Really?" Zicui was a little moved.

To be affirmed by the little lady is more precious than real money!

"Of course, it completely exceeded my expectations."

It is indeed not easy for Zicui to find a replacement in such a short time, and these things are indeed usable.

"Alright, let's play in the sand with me." Li Yewu didn't say much, and took Zicui to work again.

……

No one bothered him this night, and there were bottles and cans, so Li Yewu decided to try to refine pure silicon.

However, pure silicon needs chlorine and hydrogen to be filtered again to remove impurities, but these two gases also need to be refined.

Li Yewu had no choice but to tinker with all kinds of "poisonous gas" all night.

It was hard to make it out, and they had to be led to the urn for high temperature heating, and either the "poisonous gas" leaked in advance, or the urn could not stand the chemical reaction of chlorine and crude silicon.

All in all, the road is very winding.

Until the sun rises, only a small jar of pure silicon is extracted.

Looking at this hard-won pure silicon, Li Yewu was full of emotion.

This night, I was about to be poisoned by poison, dizzy, nauseous and uncomfortable, it was really difficult.

Zicui is also a face for the rest of her life.

She missed the story of the gray iron made of coarse silicon, only when the little lady was still working to change the tenacity of the shovel.

In the face of a confused future, the little lady will not give up, what does she have to give up?

Moreover, the little lady has been tinkering with stones and gravel in the middle of the night, and she doesn't know what is going on, and the good sand and stones become dangerous through the hands of the little lady.

Not only do they smoke, but the smoke collides with the sand and sparks, and even bursts the urn.

She had to wonder if the little lady had begun to develop gunpowder again.

Thinking of the gunpowder that could blow up the mountain that day, Zicui was strong and energetic.

After all, there is no one in the palace, and if they have an accident at this time, they really don't even have a corpse.

In this way, he finally stayed up until dawn, and the torture ended with dawn.

Being able to live in this world safely and comfortably greet the morning light, Zicui is particularly moved.

Before she could feel the preciousness of life, the little lady immediately took the box of things that had been pickled in the light of fire and danger to the Iron Smelting Bureau again.

What can Purple Emerald do? can only sacrifice his life to accompany the gentleman.

What Zicui didn't expect was that they also stayed up all night last night, and more than half of the shovels and hoes in the courtyard were repaired.

Speaking of songs, they have been secretly rubbing and quenching gray iron last night.

Fortunately, the gray iron and the white iron look the same to the layman, as long as the insider does not say it, almost no one can see the difference.

Because of this, they have secretly upgraded the performance of iron tools without even realizing it.

In just one night, the coarse silicon for the singer's head was used up.

He was planning to boil a new crude silicon according to the method provided by Li Yewu.

At this time, Li Yewu came.

Yan Ge breathed a sigh of relief: "I was just thinking about going to the mansion to find you." ”

Although Li Yewu had already handed over the method to them, they were worried that they would come out of the basket during the operation, whether it was the first time to do it, or they hoped that there would be a "master" by their side.

Li Yewu smiled: "It's not difficult to boil crude silicon, it's just to put the toner and sand together and smelt it at a high temperature, it's much easier to have a big furnace here than the broken iron pot in the palace, you can do it."

And the sand is enough, you can experiment casually, not enough to go back to the palace and dig it yourself. ”

Everyone: "......"

The little lady's heart is really too big, bigger than the master's.

None of them believed in themselves, where did the little lady get her confidence......

Moreover, he really dug up the master's martial arts training ground, and he had to die of anger when he came back.

They wouldn't dare do that......

It's better to go outside and look for river sand.

Li Yewu didn't care about this anymore, and even pulled away their only reliance.

"You guys study hard, no problem, I have more important things to do with Xingge."

Li Yewu didn't look back.

Yan Ge, who was forcibly taken away, was a little uneasy: "Little lady, is it really okay for us to go away like this?" ”

"You have to learn to let go of them to grow."

"......" sings.

Although the truth is so, wouldn't it be too hasty to let go so suddenly?

Li Yewu didn't answer this question, she took out a box of new elemental materials from her arms as if she were offering a treasure.

It looked like shredded silver, and was a little brighter than coarse silicon.

"What is this?" Sage was a little confused.

"The pure silicon I purified last night. You should think that it is purer silicon without impurities. ”

He nodded as if he didn't understand, but he felt that the name was strange.

"I wonder what this silicon does?"

"I don't know, the details will have to be clarified through practice, but I think that with this forging white iron, maybe you can get gray iron with better purity, so you should try it quickly."
