Back to the Three Kingdoms and become a python

"Blow air in and see if it leaks."

A man came out, puffed his cheeks and blew into the cowhide bag until his face was red and his neck was thick. Finally, he filled the bag with a little air, and then everyone carried it and threw it into the creek.

Several men also jumped down, first stood still, and then squeezed the cowhide bag hard according to the instructions of the craftsman, to see where the air would leak.

After such a squeeze, the effect naturally came out. There were air leaks in several places, including the places where the iron pipes were connected. Bubbles bubbled up, and the craftsmen recorded them one by one.

"It seems that the joints are leaking air." A craftsman said.

Because it is made of several pieces of cowhide, it is indeed easy to leak air at the interface. Lin Bei is also anxious to see what they use to sew the cowhide bag, but unfortunately no one can translate it. , so I can only give up.

"Why don't we sew two more layers of cowhide at the joint?" a craftsman suggested.

"Or let's process it first, the cowhide will shrink a little after processing, maybe it will cover the leak?"

The craftsmen unanimously agreed on this method, so they disassembled the cowhide bag and began to process it.

It was the first time that Lin Beishang saw the ancients concocting things. The concocting method is also called soaking and roasting. As the name suggests, it is the method of steaming, boiling and roasting. It is very simple but very practical.

The craftsmen first throw the cowhide into warm water and soak it for a while. The warm water will melt, which will make the cowhide loose. The cowhide will shrink under the action of fire, allowing the oil to melt into the leather. After doing this several times, the oil-soaked cowhide becomes extremely tough, and finally it can even reach the point where it cannot be cut by a knife, and because there is a lot of oil, so Corrosion resistance is quite strong.

Of course, this was all seen by Lin Bei. As for what he couldn’t see, there were some special things that the craftsmen even applied to the cowhide. The resulting cowhide looked greasy black and shiny. strong.

Dozens of craftsmen worked together until dark. Finally, a piece of cowhide was finished. Mrs. Feng took out a needle and stabbed it hard at the buffalo hide. The cowhide was slightly dented, but the needle bounced off. I can't even pierce the needle.

Lin Beixin said Niucha, and Mrs. Feng nodded and smiled, "It's done."

After the meal, the craftsmen continued, but Lin Bei went back to Longtan first. On the second day, Lin Bei rushed to the school, and the new leather bag was sewn again.

Still blowing the air test, this time after putting it into the water, the effect is quite different than before, there is only one place where the air leaks, and that is the joint between the iron pipe and the cowhide.

The remedy this time is to wrap another piece of cowhide around the iron pipe to make it stick closely to the iron pipe. After finishing, finally all places are airtight.

"Double-layer insurance is still very useful." Lin Beixin said.

After the cowhide bag is made, the next thing is relatively simple. After unpacking the cowhide bag again, several craftsmen went down to the biogas digester, pasted the cowhide around the digester, and left two openings. I will use two or three layers of cowhide to sew all these openings. If this is not safe, then I will add a layer of clay on top, so that even if there will be air leakage in the end, it will not leak too much. Either blocked by clay, or immersed in clay, the chance of danger is not high.

Someone had already brought several large barrels of elephant excrement from Xishan Township, and put them into the digester one by one. Lin Bei watched from the side, and waited until the digester was filled with more than two-thirds of the excrement. , Lin Bei signaled that it was all right, so he sewed up the cowhide and covered it with clay.

"My lord? Is it like this?" Cui Lan asked.

Lin Bei nodded and looked at the weather. The weather is very hot, and the fermentation of manure will be quite fast. Generally speaking, the time for modern biogas digesters to produce biogas is about one week to ten days. The higher the temperature, the faster the biogas will be produced. Quick, sometimes it can be formed in two to three days, Lin Bei hopes that it will be successful in one go.

ps: In fact, this method of concocting takes a long time, and some even take several years. The time is shortened here.

Chapter 1 Selected Farms

The biogas digester was repaired, and the elephants were caught. The next thing Lin Bei had to do was to work on the farm.

On the second day, Lin Bei still went to the school and saw craftsmen and peasant husbands building houses.

These houses are intended to be lived in by folks who build roads, so they are built in a very simple way. They are all Datong pavement, that is, there are wood on the head, wood on the floor, and nothing else. Of course, this is the same condition in this era. , it is already very good to have a place to sleep, don't even think about luxury villas.

Wang Laicai was left here by An Zhongzhi, and when he saw Lin Bei, he came over to report the situation: "My lord, Mr. Tingchang entrusted someone to send a message last night. Around noon today, the three thousand civilian husbands should be able to arrive."

The recruitment was very fast. Lin Bei thought it would take several days to recruit people, but he didn't expect to be fully recruited in less than two days.

After Wang Laicai's report, Mrs. Feng also came: "My lord, there seems to be something wrong with the digester."

Lin Bei was startled, and looked at Mrs. Feng, who hurriedly said, "Since last night when I was ugly, the night watchmen have noticed that the biogas tank feels warm to the touch. My lord, why is this?"

hot to the touch?Lin Bei feels relieved now, it’s good to feel the heat. This means that the excrement in the biogas digester has begun to ferment, and the organic matter is decomposing, so heat will be formed. But since the heat can be felt, it means that the thickness of the biogas digester is still low Not enough, it needs to be thicker, or the temperature inside will radiate cooling.

The digester was thickened by another half meter, and Cui Lan also rushed to the school, accompanied by Bian Ji, who came back earlier than An Zhongzhi.

"My lord, congratulations, my lord." Bian Ji congratulated Lin Bei when he saw Lin Bei.

Lin Bei was able to speak now: "Where does joy come from?"

"Hasn't the biogas pool been completed? This is the first joy. The long-nosed beast has been caught. This is the second joy. The folk husbands have also been recruited. Today they will arrive in Xishan Township. This is the third joy. Such a three-happy event, isn't it?" Congratulations?"

Lin Bei was delighted, this Bian Ji could really speak, but Bian Ji only saw the joy, but could not see the worry hidden behind the joy.

First of all, it is not sure whether the biogas digester can eventually form a biogas forest. If it needs to be reworked, it will take a lot of work. During these times, the long-nosed beast will add a lot of burden to the people of Xishan Township. But eating, drinking, and scavenging for the peasants is a big project, and it is quite strenuous just to cook. After all, there are three thousand people, and the trees in Fushan will suffer.

Lin Bei has been worrying about these things for a long time, and he dare not forget the environmental protection issue for a moment. At this time when Bian Ji came back, Lin Bei happened to ask them.

Lin Bei told Bian Ji to ask Bian Ji to tell others that it is okay to cut down trees for firewood, but you can’t cut down a century-old tree, you can only cut down a small tree. In addition, charcoal needs to be reserved for special storage, and, When cutting down trees, if he saw little hares or wild eggs, catch them alive or bring them back, Bian Ji didn't understand what they meant, but Bian Ji followed Lin Bei's instructions quite a bit.

Because the folk husband is coming soon, the people in Xishan Township have become more and more busy. After discussing with Cui Lan, Mrs. Feng and Cui Lan thought that there were too few people cooking, so she asked Wang Laicai to find someone to go back to the village and take the leftovers from the village. Those old and weak women and children shouted over. Although these people can't do the physical work, they can do it by adding firewood and fire. Anyway, they have to cook more than 3000 people's meals, so it's nothing to have more than a hundred people. .

The stonemasons also began to wander around the school under the protection of Orion. They had to find out where the stone was most suitable for cutting into slate. It would be even better if there were any additional discoveries. There are still many mines in this era, maybe these stonemasons Can find some veins.

Although there are quite a lot of things, they are all proceeding in an orderly manner. As for Lin Bei, he still went to the forest to find the address of the farm, but the progress was not much.

It is too difficult to find a natural breeding farm, because Lin Bei also hopes that the breeding farm is not too far away from the school, but unfortunately there is none of the matching conditions.

At noon, Lin Bei went back to the school to eat. He heard from Wang Laicai that the large army of civilian husbands was about to arrive in Xishan Township. It was estimated that they would come to the school to spend the night here tonight. Lin Bei felt that time was really tight.

After eating, Lin Bei set off again.

Only six or seven miles away from the school, Lin Bei saw some craftsmen who came out to look for stones, and it seemed that they had already gained something.

"The stones here should be suitable for making slabs." A craftsman said.

"Well, this stone vein looks quite big, so the stone material is there, but I once heard the master say that the adults said that we are not allowed to cut down big trees. There are many big trees on this stone vein. Yes."

"Just dig it out."

"The 30-mile stone road, how many stones have to be dug out, I am afraid that this place will have to be hollowed out, but it is not bad to dig a few big trees."

"It's a pole, it's a pole."

Lin Bei didn't show up, but just quietly listened to the craftsman's discussion. After listening, Lin Bei bumped his head against the big tree, thinking how stupid he was. There is no need to go to such a ready-made farm here. Looking for it?

Stones need to be dug here to obtain stone materials, so a fairly large open space will definitely be dug. Anyway, some walls can be built around it. Once the digging is completed, some water will be drawn, some soil will be drawn, and finally some plants will be planted. The farm will be formed, why bother to find it.

But in this way, the time will be delayed until next year. What should we do in these few months?

"How about this? Let every household raise some hares and pheasants. These two animals are not like proboscis beasts, and there is no burden to raise them. After the Chinese New Year, there should be little rabbits and pheasants. Let the villagers keep the big eggs as a welfare for the villagers, while the small ones will be handed over and thrown into the farms. As long as the breeding continues, no matter how much the villagers eat during this period, they will not be eaten. In the past few years, there will always be a day when it can be raised."

At that moment, Lin Bei made up his mind and prepared to do just that.

ps: Ask for recommendations and favorites.

Chapter 1 Deep in Fushan Mountain

In this way, the matter of the farm came to an end, and Lin Bei no longer needed to worry about it.
