North and South groceries

That Mrs. Zheng was imagining her future life with hope, but she didn't know that the owner of her golden thighs was worrying about the safety of her brothers and sisters.

It's not just the Zheng family. In their area, many people regard Luo Sanlang as a big tree. They all know that they can enjoy the shade by leaning against the big tree, but they don't know that standing in Luo Yong's position, the things he did , What kind of danger will it bring to himself and even the people around him.

The promotion of various technologies will inevitably bring about changes in the social structure to a certain extent. The status and wealth of many people who used to be in high positions are likely to be shaken because of this, and the anger and hatred of these people, With the current Luo Yong, it is absolutely unbearable.

The promotion of papermaking technology this time, Luo Yong actually took a chance on the timing. Li Yuan had just passed away, and the whole country was in a sad and delicate atmosphere. Luo Yong guessed that those people would not jump up at this time. Bounce.

After experiencing the change of Xuanwumen back then, there were successive natural disasters all over the country, which made people panic. To be honest, the position of the sage today is not very secure.

This summer, the Emperor Taishang passed away, and the mourning atmosphere in Chang'an City was somewhat tense and delicate. Anyone with a little discernment would know to keep a low profile at such a time, for fear that one day the sage would suddenly remember to kill a few people to stand up. At that time, I will label you as disrespectful to the emperor, and where can I go to reason.

But now it's almost two months since the death of the Supreme Emperor, and the string in Luo Yong's mind is getting tighter and tighter.

With Luo Sanlang's current ability and status, if he confronts those aristocratic family interest groups head-on, he will probably be crushed to the ground by those people.Of course, if those people really plan to attack Luo Yong, they have to consider Luo Yong's influence. Although the crushing process is easy, the consequences of crushing are not so easy to bear.

But after he was really crushed, no matter how painful the other party paid, the damage had already been done, and the dead would not be resurrected.

If possible, Luo Yong didn't want to give anyone the chance to hurt him and his family.

The current situation, how to deal with it, Luo Yonghe thought about it, and finally thought of backgammon, which was popular among students when he was in middle school.

At that time, Luo Yong understood a truth from this simple little game, that is, when you are playing games with others, you must never give up the initiative easily. The more critical the moment, the more violent an attack must be launched.

Calculating the time, by the time the Champa rice on their side was harvested, the corn on the other side of Chang'an City would almost be ripe.

I don't know how today's saints want to promote this grain variety that appeared out of thin air. With that person's political sensitivity, no matter how you think about it, it is impossible to let such a good opportunity to sing praises.

When their wave of publicity has passed a little bit, Luo Yong's eucommia gum will probably come out.

In such a torrent of rapid social and economic development, wealth and crisis coexist, and almost everyone is busy avoiding crisis and fighting for wealth. Presumably, at such a tense moment, few people should be thinking about cleaning up He, Luo Sanlang, was right, after all, it was not the hatred of killing his father and taking his wife.

In addition, in case someone secretly wants to trouble him, those people coming from the direction of Lishi County will first pass through his sheep pen, and then the Xu's guest house, in order to quietly touch the Luo's yard, which is basically is unlikely.

Not far from the courtyard of Luo's house, the courtyard built by Luo Yong's apprentices is filled with people every day, and there are people like Wang Dang, who also live not far away. Luo Yong believes that if something happens to him, None of them will stand idly by. Generally speaking, the Luo family is still safe.

The only thing that makes Luo Yong a little bit concerned is that there is no deployment at the east of their village entrance, in the direction from Xiaohe Village. You can touch Luo's courtyard, which is a hidden danger.

When the eucommia leaves on the slope came back, Luo Yong decided to set up the place where the eucommia gum was processed, and then build some houses and put the workers there directly, which could serve as an outpost to some extent.

Thinking in his mind, Luo Yong pricked up his ears to listen to the movement in the courtyard, and there was no other sound except the five pairs of snorting and the cooing of chickens, so he fell into a deep sleep.

Early the next morning, Luo Yong first went to the slope to see the growth of the Eucommia trees, and then went to the east of the village entrance to have a look.

There used to be a large flat land here, which was dug out by villagers digging yellow mud. The yellow mud here is fine and sticky enough, so it is most suitable for throwing adobe.

With such a large piece of flat land, there is naturally enough space to set up a processing workshop or the like here. The only problem is that it is not convenient to get water.

Among the several extraction methods of eucommia gum, the simplest ones are lye leaching method and fermentation method. The lye leaching method is fast, but a large amount of alkaline water is discharged, which causes serious environmental pollution. Relatively, The fermentation method takes a longer time, but what is discharged is naturally corrupted organic matter, which basically has no impact on the environment.

Regardless of the alkaline leaching method or the fermentation method, a large amount of water is required to wash away impurities during the extraction of eucommia gum, but there is no water source in Luo Yong's fancy place.

Faced with this situation, either solve the water source problem or change the place.Luo Yong didn't want to change the place, and besides, there was no second piece of flat land around their village, especially the place near the creek, where the terrain was generally steep.

Moreover, it is obviously irrational to build a workshop by the stream, because there are mountains everywhere in their place. Once it rains heavily, the rainwater from the mountains will pour down from these ditches. If the workshop is too close to the stream, it is likely to It will be washed away by mountains and rivers. If it is not close enough, it still has to solve the problem of water intake.

This problem of water intake is not easy to solve. There are no plastic pipes these days, or else a water pipe can be brought down from the mountain.They also don't have big bamboo here, otherwise they could use bamboo slices to divert water.

If you dig ditches, you have to consider the problem of anti-seepage. Most of the mountain streams here are trickles. I don't know if there will be any left.

When it comes to anti-seepage, Luo Yong naturally thinks of cement.

Cement is really hard to make. Luo Yong has been looking for relevant information in this area for a long time. The manufacturing process of cement is not too difficult, but the raw materials are more troublesome. They don't have much limestone or Clay, I heard that slag can be used instead of clay, but the problem is that this is not a mining area either.

The transportation is so inconvenient these days. You asked people to pick limestone clay from thousands of miles to come here, and after a lot of hard work, you can finally make such a little bit of cement. Is it worthwhile?What is enough for?

In order to solve this problem, Luo Yong plunged into the pile of books again, and locked himself in the room day and night, not allowing others to enter.

As for the daily work of making soap and selling soap, Peng Er and Er Niang are not too strenuous. The main reason is that there is no other work at home in the past few days. I just made a batch of fermented bean curd a while ago. Hey The work of the pig was also handed over to the Zheng mother and daughter.

Emperor Tian paid off, after retreating for several days, Luo Yong finally found a very useful piece of information from a pile of humble printing paper.

This stack of printing papers was downloaded and printed out from the Internet by a graduate majoring in civil engineering when he was doing his graduation thesis. Interested in this profile.

I saw the title "Burning Loess to Replace Cement" on that A4 typeface - Geotechnical Research Office of Shaanxi Institute of Water Conservancy Science.

Hahaha!

What is the most interesting thing on the Loess Plateau?Loess!
