While everyone was talking about Yaoyao, in the afternoon, after the morning etiquette class, Yaoyao also came out with the emperor, and of course there were many people accompanying him.

The group first came to Yaoyao's residence in the west of the city, but when she came back, Caiyun, Xiaoqing and the others also went out. After all, she became the prince's concubine so she must gather together to discuss and discuss.

As a result, this happened to be missed. Yaoyao went out without a key, but fortunately, this world has light skills, so she directly asked Li Chengqian to take her over the wall. Then, she went inside and took out the things.

The previous performance venue was not allowed to be kept in the venue, but if you twist the screws with your hands, you will have to screw them to the point.

So, this time she came back, she also came back to get the wrench for the emperor. Not long after entering, the civilians who happened to live nearby on the street naturally saw the grandeur outside.

But no one dared to open the door and see it. After all, who would be so stupid that he would come out and bump into the nobles at this time. Maybe there is another one in this team who is the emperor. Even if it is not the emperor, the prince is not something they can look at.

At this time, in a doorman diagonally opposite, a servant looked outside through the crack of the door, while secretly sighing: "This family is afraid that they will fly up to the branches and turn into phoenixes!"

Behind him, there were also many curious people lying in the crack of the door to look at it. In fact, Yaoyao didn't want so many people to come, but then she thought, isn't there so many people that others don't know that this is where she once lived?

Therefore, she wanted the emperor to wait at the intersection, but she couldn't help but extinguish the idea of ​​taking out the things. Since that's the case, it would be better to be a royal relative. At least one day when she was there, Caiyun would not be bullied.

Soon, Yaoyao and Li Chengqian moved out the things. It was a bit large wooden box. There were hundreds of wrenches inside. Yaoyao also held a universal wrench in her hand, and then returned to the emperor's car with Li Chengqian.

The emperor's car was naturally larger than the luxurious carriage that Yaoyao rented in the carriage store. After returning to the carriage, Yaoyao then showed the emperor the universal hand.

Perhaps such a situation, in the eyes of others, she felt that she had become a phoenix after flying up to the branch, but why did she think that this was like returning to the crime scene and confessing to the abandoned tool of the crime?

Yaoyao took out the universal wrench and showed it to the emperor, and said, "Hey, that's it!"

The emperor also took it over and looked at the universal wrench up, down, left and right, and naturally he was confused in his mind.

Then he said, "How to use this thing?" Moreover, it was heavy in his hand. I'm afraid it was made of iron. Although he had already admitted that Yaoyao was an immortal disciple, he was still very surprised to see such a tool at this time.

Yaoyao then took the universal board hand back and turned the roller on it, explaining to him: "You want to turn here, and then the mouth will be opened, and then you can easily screw out the screws."

After watching it, the emperor's eyes glowed instantly and said intimately: So that's it!

"This thing is really exquisite!"

"But why does your master have so many of these things? Where did this iron tool come from?" the emperor looked at Yaoyao and suddenly asked.

Yaoyao also replied: "This is exactly what I want to say. Although my master is an immortal, he can smelite, even steel, and even produce things that you can't smelite. The materials used in the venue are actually not completely iron, but a metal called aluminum."

"Lu?" Emperor.

"That's right! Next to the golden character, there is aluminium of Lu. It is a metal with different chemical and physical properties from iron, and its content is even richer than iron in nature. It should be almost twice as much as iron. It is just because it is not a simple thing to extract aluminum. Therefore, even the most experienced iron smelting master does not know the existence of this metal. It can even be said that no one except my master has known this metal so far." Yaoyao's words shocked the emperor again.

Then the emperor also said, "Then can you refine aluminum?"

If possible, wouldn't it be...

Yaoyao nodded: "Yes!"

Before the emperor could be happy, Yaoyao continued, "But it's useless."

"Why?" the emperor.

"Because there is a gap between theory and reality, although I know how to extract it, aluminum cannot be extracted casually. It is many times more complicated than refining iron, and it cannot be produced by burning it with charcoal. The reason why it can stay so many times and build venues is because my master spent many years to accumulate. My master once had a factory that could automatically process aluminum. Do you understand? It is the kind of factory where you can extract aluminum from the stone with your hands up in front of your chest and do nothing, and you don't need to participate at all."

"If you want to see it, you only need a person to watch it. The pieces of aluminum as small as silver ingots are cut into pieces and built into pieces and appear in front of you. But I don't know how the factory was built. Moreover, the factory was also destroyed by my master. At that time, I was still young, just like the osmanthus cake my mother made back then. I only knew how delicious it was, but I don't remember how it was made. Even if I wanted to try it, I couldn't make the taste of the past. The osmanthus cake was fine, but it was just not delicious when it was made, but if you refine aluminum, you wouldn't see the shadow of the last aluminum ingot."

Yaoyao seemed to be saying something ordinary, but to the two of them, they seemed to hear something incredible.

Li Chengqian's first reaction was, why did I listen, it seemed like Miss Yaoyao was making up stories again?

But this time Yaoyao really didn't make it up, because it was true. It was just a factory for refining aluminum, she knew it very well in her mind.

The emperor looked at the wrench in his hand, and after a while, he sighed and said, "That's a pity!" He was actually an ambitious emperor, otherwise he would not have attacked everywhere in the past decade to capture the current large territory for Beichen, and so that the surrounding foreign tribes bowed down and surrendered. This is also a depressed place for Yaoyao. In fact, she also wanted to fight, but the problem is that Beichen now has no war, but this is good. After all, wars and other things will always kill people. Wars may make her happy alone, but it will make countless people lose their parents, brothers and sisters.
