Walking through the school, Guo Bin did not go in. Because when Liu Bi came to Yangzhai, he often came to inspect the sentry, so Guo Bin was most familiar with the school.

The layout of Xicheng District is similar to that of Yangzhai Old Town, but because it is a new urban area, the planning is more reasonable than that of the old city. Within the courtyard wall on both sides, which is more than one zhang high, is the "li", that is, the private house. Generally speaking, in order to facilitate government management and prevent theft, each "li" is surrounded by high walls. Xicheng District is naturally no exception, but it is more refined, and each village has a large courtyard wall.

Because it is a townhouse, it is easy and convenient to modify, just add a wall to the gable on one side of the house that connects to the house in front. The houses are all five rooms in a row, and when the foundation was first dug in mind, the problem of heating in winter was taken into account, so a ground dragon was dug under the room, and sawdust was stuffed in the winter, and it was lit to let it slowly spontaneously combust, which could burn for the whole winter. Now that the houses have been completed, and it is already November, it can be said that the sky is freezing and the ground is freezing, so the earth dragons of each house have already been ignited, and the heat from the soles of the feet can directly warm the heart. Before they became exiles, how could they have tried such a warm and harsh winter?

When Guo Bin came, he saw the villagers who were digging a pit, and he turned back to Xu Shu and said, "Yuan Zhi, has the work of the biogas digester begun?" ”

Xu Shu, who has been following behind, said: "Back to the lord, according to the lord's instructions, the biogas digester will be put into use in the spring of next year, and it just so happens that the villagers' houses have been built, and they have been built during the winter slack time, and they can be put into use in the coming year." ”

Guo Bin nodded and said, "Well, are there people from Fulong Villa to guide you?" ”

Xu Shu returned: "Each household has a biogas digester, and a group of five households takes turns to excavate, all under the guidance of people from Fulong Villa. ”

Guo Bin nodded reassuringly and did not speak. Xu Shu did things, he was very relieved.

Speaking of this biogas digester, it was originally dug by Guo Bin in Fulong Villa. Why did you think of such a thing? Just because the village is full of feces, even the road is full of animal feces. In order to deal with the mountain of manure, Guo Bin had people dig a biogas digester. He was born in a rural area, and there was a biogas digester in his home before he crossed, and the government called for the construction of each biogas digester with state subsidies. Although Guo Bin had not dug it, he had seen it, and he understood the principle, so he tried to build it in Fulong Villa.

If you want to say why there is so much animal manure in Fulong Villa, it is still due to the breeding industry. At the beginning, Fulong Villa, which started with a very low threshold breeding industry, not to mention chickens, ducks, and geese, also raised rabbits, cattle, sheep, pigs and other poultry. There was a movement, and the barking of dogs, chickens, and sheep was heard endlessly. That's not all, the pile of animal manure has become a big headache in the village.

Because the planting season is over, it is no longer possible to grow food, so although the land has been cleared, it has not yet been cultivated, and it is difficult for people to find time to collect the manure and cultivate the fields. Therefore, Guo Bin came up with such an idea.

It is not impossible to say that the manure is thrown directly into the field to fertilize the field, but the nutrients are not good to penetrate into the soil, and it still needs to go through the steps of decomposition. Therefore, compost is often seen in rural areas, that is, the manure must be piled up first, and the ubiquitous microorganisms are used to break it down, and then sprinkled in the field to make the crops grow better.

The biogas digester collects the biogas produced when the manure is decomposed, transports it to the ignition place through the pipeline, and then uses the biogas to cook or illuminate. When there is less biogas, dig out the manure inside to fertilize the field, which is a good trick to count in one fell swoop, and it is Guo Bin's way. This kid is lazy, he always thinks about how to count in one fell swoop, tries his best to squeeze profits, and never does a loss-making business.

Unexpectedly, after overcoming various difficulties, the biogas digester put into use won unanimous praise, and Guo Bin's experiment in Fulong Villa was a success.

In addition to the gas production is not as good as that of later generations, the biggest technical difficulty of the biogas digester in this era is the sealing and transportation of biogas.

Guo Bin tried everything he could, using iron pipes, copper pipes and the like, and finally proved that unless they were cast, and they had to be made very thick, they could not be done with the current technology. It's just that this is not only not easy to transport, but also extremely expensive to build, and is not suitable for promotion. Just when Guo Bin was anxious, he was still Ma Jun's grandfather, and Ma Lao had an idea.

Isn't it just a pipe? Take bamboo, isn't it a good pipe to poke the bamboo joints open? The elbow is not easy to do, so it is cast in iron; What about the ignition? What else can I do, pour it with iron, Ma Lao is not a fairy! Is it not easy to seal at the joint? It is enough to smear the joints with cement and fix them, so that not only has good sealing, but also does not fear that the enemy will drop rockets into the city during the siege war, causing a fire. And for safety reasons, the pipes are buried in the ground and covered with stone slabs, which greatly increases their service life.

Therefore, after reducing the cost through this series of methods, the construction of biogas digesters has the possibility of promotion.

Today, biogas digesters in Xicheng District, Yangzhai County, are built in small courtyards of each household, and pipes are buried underground to increase safety.

As a modern person, Guo Bin really can't stand the living environment full of feces, and every time he sees feces flowing everywhere, he always has a feeling that he has nowhere to put his feet. In the Han Dynasty, when poultry was widely raised, a biogas digester may be the only way to get rid of this environment and achieve a hygienic and safe living environment.

Guo Bin did not think about controlling environmental sanitation through administrative means, such as spitting and fining 50 yuan. But this is just a stupid way to treat the symptoms but not the root cause, and it is very inconsistent with Guo Bin's style of doing things with small input and large output. The lack of manure in the biogas digester will make the villagers feel that even a lump of poop is extremely valuable. So they will educate children not to defecate anywhere, they must come to their own latrines, and the so-called fertilizer water does not flow into outsiders' fields!

The only drawback of this measure is that every time Guo Bin goes to the countryside to inspect, he will always receive a warm welcome from countless villagers. They all wanted to drag Guo Bin to their own house to go to the toilet, which made Guo Bin have a headache and sighed: "Who knows that the feces in the pit are all hard." ”

Today's Xicheng District, although it has ended the initial high-tide period of construction, is still busy.

The men were outside building and digging the digesters, the children were in school, and the women were tidying up their homes and feeding the chickens and ducks distributed to each family in the company. Therefore, most people will take orders from the quilt factory in Fulong Villa, gather in the village hall, and make clothing and leather shoes under the guidance of technicians sent by the quilt factory. Once they have learned, they can take the materials to work at home.

Therefore, the residents of Xicheng District, who have lived a good life, cherish their lives today. They knew that all this was due to the order of Guo County.

When they had no food and clothing, and were hungry and cold, it was Guo County who sent people to bring them steaming porridge and rice; When their whole family was defenseless and trembling, it was Guo County who sent someone to send them fine linen cotton clothes; When they stayed overnight in the wilderness and there was no tile on it, it was Guo County who sent people to send bricks and cement to build houses for them; When they felt hopeless in this life, it was Guo Xianling who sent someone to pick up their children and send them to study, giving them hope for life; When there was no place under their feet, and they were almost about to be eaten, it was still Guo County's order to give them work, so that they could rely on their only remaining strength to support their families.

Guo County Decree let them work with dignity, so that they can live like individuals, it is also Guo County Decree who saved their family, and also let them live a good life that they have never imagined in this life, they can only throw off their arms and work hard, not to repay Guo County Order's great kindness, but to make themselves feel more comfortable.

Further west, there is a "city" surrounded by residential areas.

At this time, there is a wall around the city, and traders can only enter and exit through the market gate, so as to restrict trading outside the city, and the market gate opens and closes on time. There is a city building in the city, also known as a pavilion, a flag pavilion or a city pavilion, and the official office of the city is located here. The officials in charge of the city are called mayors, and the gates of the city are guarded by prison guards.

In order to facilitate business management, the shops and vendors in the city are arranged according to the types of commodities they operate, which are called columns, shops, times, columns, markets or markets. The passage between the rows is called a tunnel. There is also a warehouse for storing goods, called a store, after the column. In addition to private businessmen, the government also sent people to sell government-run handicraft products and other goods in the hands of the government.

Although Guo Bin, who came from later generations, was extremely disdainful of such a strict management system, as a qualified court official, Guo Bin had to act in accordance with the requirements of the law. Because it is a new town, everything is new, even the establishment is new. Therefore, Guo Bin transferred the first batch of students from Fulong Villa to learn to manage the "city" under the guidance of Xu Shu, so as to exercise their practical ability and lay a solid foundation for taking on more important positions and solving more complex things in the future.

The cultivation of talents is not to cultivate flowers in a greenhouse, but to gradually expose them to wind and rain, and those who can survive are the real talents. And most of these children from poor families did not disappoint Guo Bin.

These people are generally fifteen or sixteen years old, and they have learned no more than 2,000 common words, and they have only learned addition, subtraction, multiplication and division in mathematics. But everyone works very seriously, and they all know that it is really hard to have such an opportunity, and this may be their only chance to get ahead.

They are all the first batch of students of Fulong Villa Academy, because they are not young when they go to school, many things are learned faster than children, and they have to practice while studying, so what they learn is extremely practical. In this way, many people still choose to go to Yangzhai County Government School at night to participate in tutorial classes, in order to improve themselves faster. Their families are now in Fulong Villa, all of them are extremely decent families, because they went to the city to "become officials" and have a career, so most of them are burdened with the expectations of a family.

According to the agreement of Yangzhai County Construction Co., Ltd. when it was first established, two "cities" were built in the new area, and although the land was owned by the county government, the buildings on the ground were the property of the construction company. Therefore, the shops and stalls inside should pay rent to the construction company. At this time, the construction company has already received its first dividends, and the rapid rate of return has made shareholders extremely optimistic about the company's prospects. It is true that Yangzhai New City, which Guo Bin started, has a rate of return that they can't imagine now.

Everything in Yangzhai County seems to be on the right track.
