Lu Xiaoyu felt that this Yun'an City was really not safe, and before he had walked two miles, more than a dozen girls were secretly looking at Lu Shu.

At this time, Lu Shu suddenly said: "I will accompany you in Yun'an City for a few more days, let's make a similar livelihood and then I will go to the Wuwei Army to report, so that I can also walk around the city more and familiarize myself with this Lu Zhou world as soon as possible, for the ......"

"You go to the Martial Guards now," Lu Xiaoyu said calmly.

Lu Shu: "???"

"Negative sentiment from Lu Shu, +666!"

But Lu Shu can't really go to the Wuwei Army now, he has to arrange things in the city first.

Lu Shu suddenly asked: "I have carefully observed, Zhang Weiyu and they use the leaves of a plant to rub their clothes, I asked him if there are any other cleaning methods, he said that everyone uses this leaf, it is quite easy to use, so there seems to be no such thing as soap here, and the process of soap is quite simple......"

Lu Shu once saw that the cause of the invention of soap was actually a coincidence, it is said that someone accidentally got the grease into the extinguished charcoal, he was worried about causing a fire, so he quickly took out the charcoal and grease, and when he washed his hands, he found that the washing was particularly clean.

This kind of coincidence can sometimes become inevitable, because even if there were no coincidences, scientists would have worked out it when they were studying chemical elements.

But this Lu Zhou's world is different, first of all, there are not many players who are committed to chemical research, and secondly, there has not been such a coincidence.

Lu Shu was complacent about his idea, and Lu Xiaoyu was shocked at the time: "If you don't have soap, do you want to make soap?"

Lu Shu: "...... What do you mean?!"

Originally, Lu Xiaoyu thought that it might be safer for Lu Shu to go to the Wuwei Army, but now it seems that it is not safe to go to the Wuwei Army!

No matter how Lu Shu listened, he felt that Lu Xiaoyu's words were a little wrong, there was no soap, wouldn't it be just enough to make money by making soap by himself?

In this era, it is certainly unrealistic for you to climb technology, and it is not realistic to make things that are too unbelievable, and people here may not be able to accept it, so daily necessities are the easiest to sell, and the cost of making soap is not expensive.

Lu Shu carefully analyzed: "You see, in fact, the process of making soap in our ancient people is very simple, caustic soda and lard boiled out, alkali I looked at it and there is indeed no here, but we have two methods, one is that we directly burn plant ash to do it ourselves, and the other is that you go to find alkali ore! The first one is of course this method, according to the ancient method of making alkali with plant ash is a bit slow, it is best to find alkali ore, with Anthony's strength to search for alkali ore, I feel that it is not a difficult task. It's easy to find alkali, and it's caustic soda when mixed with lime, and lime is there, and I just noticed that lime is used to build houses in this city!"

The alkali thing was developed and used relatively late on the earth, and it is normal that there is no one here, but it doesn't mean that it can stump Lu Shu, and it's a big deal to really burn the grass and wood ashes and slowly concoct it.

Lu Xiaoyu looked at Lu Shu in a daze, she found that Lu Shu was serious, this product really wants to make soap!

Lu Shu was still proudly said on the side: "If this Lu Zhou world enters the scientific and technological side in the future, I can't imagine that I can still be famous in their annals: the maker of soap, Lu Shu!"

"It's not something to be proud of," Lu Xiaoyu complained.

"You don't understand, science is an art, the more you delve into it, the easier it is to discover the grandeur of this world," Lu Shu sighed: "But this world has taken a different path, and they use themselves to integrate the laws, so I am afraid that they disdain basic science." ”

There is no one right or wrong, these are two paths, human beings invent technology in order to use technology, but this Lu Zhou world has embarked on another path, because they themselves are very powerful, and they use not technology but "magic", so the progress of science and technology is probably very slow.

This is the result of the strength of the individual, Lu Shu thought about it, maybe in some other world, there may be creatures who have researched technology to the point of being able to compete with the God King, but no one here really cares about this.

"Then do you think the cultivators here will have a spell to clean up their clothes or something?" Lu Xiaoyu also became serious, she was curious: "If there is, then didn't we do it for nothing?"

Lu Shu smiled: "It's good that we sell soap to ordinary people, you see that ordinary people still account for eighty percent of the proportion here, this is the market, and there is no need to sell it to those cultivators." ”

"Yes," Lu Xiaoyu suddenly felt a little sad in his heart, Lu Shu was about to make soap......

What do you say that you are the inventor of soap, and you are shameless......

Lu Shu began to get excited after thinking of his way to make a fortune: "I'm afraid the magic money in our hands is not enough to stay in the inn for two days, do you have anything from before that you can sell?"

Lu Xiaoyu glanced at Lu Shu vigilantly: "What do you want to sell?" I have gold bars, but I don't want them here." ”

This is a real headache, and the gold has become useless here......

Lu Shu thought for a while: "Is there anything else?"

"There is also a belt that I want to buy and give to you, but the people here wear pants differently than ours, they don't need belts, and they don't know any famous brands......" Lu Xiaoyu thought for a long time and said.

At this time, there was a sugar gourd seller on the side of the road, and strings of red sugar gourds were inserted into the sticks carried by the vendors, and a group of children chased after the hawkers. Lu Shule asked Lu Xiaoyu, "Do you want to eat?"

"Don't eat," Lu Xiaoyu shook his head: "Our money is still useful." ”

Lu Shu looked at Lu Xiaoyu, on the eve of the revival of the aura, Lu Xiaoyu was still clamoring to eat sugar gourds at that temple fair, but two years have passed in the blink of an eye, and Lu Xiaoyu has grown up and is sensible.

Time will inadvertently change a person, and Lu Shu thinks that both him and Lu Xiaoyu are changing towards the appearance he once hoped for.

Lu Shu called out to the vendor: "A string of sugar gourds." ”

He bought it back and stuffed it into Lu Xiaoyu's hand: "Just leave one for me." ”

"Hmm," Lu Xiaoyu replied, looking down and not knowing what he was thinking.

It's as if the world has never changed, or the world has changed, and it's just her and Lu Shu who haven't changed.

At that time, they were also very poor, but she knew that Lu Shu would definitely think of a way.

Originally, Lu Xiaoyu didn't like this world too much, and there was always an inexplicable rejection, but now that rejection is suddenly gone.

Because Lu Shu is here, where Lu Shu is, where is it not the same?

……

Some people say I want to watch the World Cup, hehe, I don't watch the World Cup, okay, it's Ren Xiaosu who wants to watch it, and I'm just accompanying him......
