These old fritters are different from the innocent, stupid and loyal followers in the palace.

For them to be able to become a monopoly in this chaotic Taihe Prefecture, there must be intricate forces behind them.

For them, Li Yewu would not trust any of them. As long as he could maintain a polite attitude, he didn't expect them to do anything.

Therefore, Li Yewu didn't frown when answering the questions, and she just fired off the smoke bomb without blushing or gasping for breath.

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

"I thought the princess wanted so many jars for some urgent purpose, but it turned out to be a false alarm. If the princess is useful to Xiao, you must say that although Xiao's abilities are limited, he will never refuse."

"Master Xu is very thoughtful. If I really have any difficulties in the future, I will definitely come to you. Please don't be stingy with your advice."

"Uh... Princess, this is what it should be, it should be."

After all, it was late at night, so the head of the Xu family and a group of waiters put down their things and left quickly without lingering.

It wasn't until they were far away that Li Yewu opened the box and checked it.

Zicui did help find a lot of things, but they were all just related to her pictures.

She wanted glass test tubes, but Zicui only found small jars containing pills or toilet water and rouge, and larger jars containing various pickles.

Zicui bought a lot of things, including several large boxes.

However, she herself was not very happy and just said in frustration.

"Madam, Zi Cui has tried her best."

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

Li Yewu saw that she was blaming herself: "The thing I want is so tricky, it's already amazing that you can help me find something similar. I dare say that no one else is as careful as you!"

"Really?" Zi Cui was a little moved.

Being recognized 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 replacements in such a short time, and these things are indeed usable.

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

…

There was no one to disturb him that night, and there were bottles and cans. Li Yewu decided to try to refine pure silicon.

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

Li Yewu had no choice but to spend the whole night tinkering with various "poisonous gases".

After finally getting them out, they had to be led into an urn and heated at high temperatures. During the process, either the "poisonous gas" leaked out in advance, or the urn could not withstand the chemical reaction between chlorine gas and crude silicon and cracked.

All in all, the road is very winding.

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

Looking at this hard-won pure silicon, Li Yewu was filled with emotion.

I was almost poisoned by poisonous gas that night. I felt dizzy, nauseated, and felt uncomfortable all over. It was really difficult.

Zi Cui also looked like she was surviving the disaster.

She missed the story of Si Ge refining gray iron with crude silicon, only thinking that the little lady was still working hard to change the tenacity of the shovel.

Facing a confused future, the young lady refuses to give up. What does she have to give up?

Furthermore, the little lady kept tinkering with stones and gravel in the middle of the night. I don’t know what happened, but the good-looking sand and stones became dangerous in the hands of the little lady.

Not only do they emit smoke, but when the smoke collides with the sand and stones, sparks will appear and even the urn will burst.

She even wondered if the young lady had started developing gunpowder again.

Thinking of the gunpowder that could blow up the mountaintop that day, Zicui became extremely energetic.

After all, there is no one in the palace. If something happens to them at this time, there really won't even be anyone to collect the body.

In this way, the torture finally ended at dawn.

Zi Cui was particularly touched to be able to live peacefully in this world and welcome the morning light with comfort.

Unexpectedly, before she could express her feelings about the preciousness of life, the little lady immediately went to the Iron Smelting Bureau again with this box of unknown things pickled in the fire and danger.

What can Zicui do? She can only sacrifice her life to accompany the gentleman.

What Zicui didn't expect was that Si Ge and the others had stayed up late last night, and more than half of the shovels and hoes in the courtyard had been repaired.

Speaking of Si Ge, they had been secretly tempering gray iron last night.

Fortunately, gray iron and white iron all look the same to the outsider, and almost no one can tell the difference unless they are an expert.

It is precisely because of this that they secretly upgraded the performance of their iron tools without being noticed.

After just one night, the crude silicon in Si Sing's head was used up.

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

At this moment, Li Yewu came.

Si Ge breathed a sigh of relief: "I was just going to see you at home."

Although Li Yewu had handed over the method to them, they were worried that something would go wrong during the operation. After all, it was their first time doing it, and they still hoped to have a "master" by their side to embolden them.

Li Yewu smiled: "It's not difficult to boil crude silicon. It's just a matter of putting carbon powder and sand together and smelting it at high temperature. It's much easier with the big furnace here than the broken iron pot in the palace. You can do it.

Moreover, there are enough sand tubes for you to experiment as you like, but there is not enough sand to go back to the palace and dig it yourself."

Everyone: "..."

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

None of them believed in themselves. Where did the little madam get her confidence...

Moreover, if the master's training ground was really dug up, he would be furious when he came back.

They don't dare to do this...

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

Li Yewu ignored the matter and even took their only support, Si Ge, away.

"You should study carefully, there will be no problem. Si Ge and I have more important things to do."

Li Yewu walked away without looking back.

Si Ge, who was forcibly taken away, was a little worried: "Little madam, is it really okay for us to leave like this?"

"You have to learn to let them go before they can grow."

"..." Si Ge.

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

Li Yewu did not answer the question. She took out a box of new elemental materials from her arms like a treasure.

This thing looks similar to chopped silver. To be honest, it is a little brighter than rough silicon.

"What is this?" Si Ge was a little confused.

"The pure silicon I purified last night. You can understand it as purer silicon without impurities."

Si Ge nodded half-understanding, but thought the name was strange.

"I wonder what this silicon does?"

"I don't know either. I have to go through practical operations to find out the specific details. However, I think using this to forge white iron may lead to gray iron with better purity, so you should try it quickly."
