While Changle was conducting a series of celebrations, Yang Heng suddenly received news from his home in the countryside that someone had reported the good news, but he did not say that it was a happy event.

When I heard that Yang Heng was going back to the countryside, Changle, Yuzhang, Xiaoniang and others would not stay in the city. They now liked that there was more than in the city. Although there was no industrial pollution in this era, the smell in the city was still very different from that in the countryside. No matter how wide the streets in Chang'an City were, the number of livestock was also quite large. Naturally, there were also people's excrement, which was the source of odor in the city, or pollution of domestic waste. That's it, so these girls didn't like the city very much. Besides, there were not many commodities to buy in this era. Whether it was cosmetics or other amusement facilities, they were all so old, not as good as Yang Heng's home in the countryside. Therefore, the girls yearned for life in the countryside very much. If they were asked to work, maybe they wouldn't yearn for it.

So, the group returned to the countryside in a mighty manner. Changle Yuzhang and Xiaoniang naturally went to find what they like to play, while Yang Heng entered the mountain.

"Butler, please let me know if there is any good news." Yang Heng first found the Butler and asked. You must know that although the valley is not big, there are many facilities inside, so Yang Heng didn't want to ask each place.

"Back to Xiaolangjun, there are several things in this valley that have been completed. I just haven't asked you to notify you. But now, I can't help but notify you." The housekeeper said excitedly.

"Oh, what's the matter? You're so happy, butler." Yang Heng was also a little puzzled. There were some things he had arranged, just to achieve results. That's normal. Are you so happy?

"Xiao Langjun. Didn't you let all kinds of stones transported in? Also, did you let those Taoist priests study the reaction of soil and turmeric? The Taoist priests made all the soil in the valley, and even made all the soil transported in the logs, but these things were very fast. Then they had no magical things, so they began to crush the stones, put some stone powder into the fields, and conducted some experiments. It was precisely because of this that they discovered a kind of stone powder into the fields. It could actually make the crops grow faster, but they didn't know how the yield was, so they asked Xiao Langjun, you are back."

"Are you talking about saltpeter?" "Yes, Xiao Langjun, have you known this a long time ago? This is not right. I have never mentioned it to anyone. Could it be those Taoist priests who failed?" The housekeeper was a little surprised.

"Okay, okay, don't guess, I've known it a long time ago, don't care where I knew it." Where did I know that there were fertilizers made of saltpeter in my previous life, so saltpeter can even be ground directly as fertilizer. However, in this era, using saltpeter as fertilizer is not supported. One is that it is wasteful and the other is that it will make the floor solid, which feels like it is not worth the effort.

"Butler, you told the three Taoist priests that you should not study fertilizers, and you should not study these saltpeters temporarily. You should study them after the houses on their side are built. This is too dangerous. After the protective measures are done, they will be allowed to study the fertilizer. If the fertilizer is done, it should be better to study the function of the slag and slurry liquid first." Yang Heng didn't want everyone in the world to know that saltpeter can be used as fertilizer, so that he will become a sinner, and may increase production in a short time. But after a long time, once the land is solidified, the grain output will be greatly reduced.

"By the way, butler, you must make an agreement with the three Taoist priests, and also with the old farmers you know. Forget it, I'll just go and talk about it myself." It's a good thing to be able to use fertilizer, but if it causes bad effects in the future, it's better not to do this kind of good thing.

Yang Heng tried his best to finally stabilize these people. They also vowed not to say it, and Yang Heng was relieved.

Next, he carefully observed some changes in the valley.

First of all, Master Sun's medicinal materials have all come out and they are growing well. However, Master Sun is not here recently, and he cannot identify the quality of these medicinal materials. However, Yang Heng seems that these medicinal materials are very lush and seem to be considered successful. If they are not successful, they may not have emerged. Perhaps the seedlings will be very thin after they emerge. It seems that these medicinal materials are very suitable for growing in this climate. In the future, Master Sun can save some time going out to collect herbs and study more cases.

"Xiao Langjun, don't you look at these grape seedlings? The survival rate is very high. Almost half of them have taken root and sprouted, and they are growing well. I just don't know how many years it will take to bear fruit."

This is also a good news that Yang Heng got. Once these grapes start to bear fruit, wine can be made, and even some other wines. It is possible that some strong wines can be made with grapes. The brewing of grain wine can be reduced. In short, the food at this time is still the most suitable food, and it can even be used as feed for raising pigs and poultry, which is much better than wasting wine making.

The cultivation of grapes will not occupy fertile fields at all, and it can even be planted in every household's courtyard. At that time, it will be done as long as it is purchased and made. Even if the people manage it, the grapes are a delicious fruit. It is also good to dry them into raisins.

As a planting experimental base, these two are considered to be effective quickly, while other types such as the configuration of good varieties and grafting research all take time, so Yang Heng didn't even ask questions. Now is not the time to produce results, and he has to wait for the old farmers to report on their own, and he will not put pressure on them.

"Butler, that's it?" Suddenly, Yang Heng saw a ray of black smoke rising into the sky. Could it be that the chimney of the melting iron furnace had been built? "Little Langjun, I haven't had time to tell you that the big chimney has been built and fixed on the mountain wall. In this way, the molten iron furnace below can change its image at any time to study the refining of some steel, which is very convenient." "Let's go, look." Yang Heng was also interested. This chimney was actually just his idea. He did not think that this would be successfully built, but it was actually

If it succeeds, the wisdom of ancient people is really amazing. Yang Heng seems to have played a role in leveraging the earth's fulcrum, or it is impossible to imagine but not to do it. Yang Heng played a role in thinking about it. People will naturally slowly study what he thought of. Naturally, Yang Heng will not give some problems to the workers. If he asked the workers to make a simple radio, it would be impossible, but more than ten years later, it might be possible to build a radio.

A tall chimney soared into the sky next to the mountain, which was a height of dozens of meters. When he approached, Yang Heng discovered that the chimney was fixed on the cliff with some iron bars. On the entire mountain, there would be a fixed iron bar at every distance. There was a thin hole in the mountain. The iron bar just came out from the inside, and the chimney was firmly tied to the mountain. There was also the part below. They actually built it by moving. If a style felt inappropriate, push the furnace body of this type aside and build a new furnace body. This new furnace body was also active. These ancient people were really good. They actually invented a combination of plug-and-play construction method in advance. It seems that they would come soon when they made computers. At least Yang Heng might use the original computer in his lifetime.
