The functions of "biogas system" and "tap water" are somewhat similar, and they are also used in two spaces, one is "taking materials" and the other is "sending gas", and the one is also transferred by an unknown space, and what the primitive people have to do is just to build a huge material pool in the biogas plant, which is the same as the water storage tank, which is also a closed material pool controlled by space, but it is the opposite of "tap water", "tap water" is lake water - unknown space - water storage tank - thousands of households, and "biogas system" It is thousands of households - material pools - unknown spaces - thousands of households.

This material pond is different from the biogas digester, not so complicated, to put it bluntly, it is just a large pit for collecting waste materials, which is controlled by space to produce biogas, and then the biogas is stored in an unknown space, and then sent to thousands of households through guò pipelines.

The "biogas system" involves three types of pipes, the first being the pipes that connect the manure tanks under all the public and household toilets, the collection of animal manure from pastures and many other organic waste disposal points, the second is the pipeline that transports the biogas to thousands of households, and the third is the pipeline that transports the biogas residue to the farm. That is to say, in the construction of this project, the workload of laying pipelines is very large, and in order to keep the pipeline firm and smooth, all of them are paved by iron pipes, and most of the iron used this time is in this piece, at the same time, so far, not counting the sewerage, all the pipelines have been used, that is, the subway, tap water and biogas system.

The first type of "reclaiming" pipeline, under the control of the space, will collect the waste at the end of the pipe every day, the collection method is the same as the logistics center, the contents of the pool will disappear completely, and after collection, it will be sent directly to the "material pool", under the control of the space to speed up the process of producing biogas, after which the biogas residue will be sent to the farm, and the biogas will be stored in an unknown space.

The family toilet here has a bathtub, a washbasin, and a toilet, and it can be said that it has initially taken the form of a modern toilet. Although the toilets of the tribesmen are still squatting pits, the primitive people are already very satisfied with the fact that every household has a private toilet, and they have not seen modern equipment, so they will naturally be satisfied. Sima Pianpian was not very satisfied, she had already asked primitive people to research and make zuò flush toilets, hoping to succeed as soon as possible.

At present, there is only one use of biogas after "gas", and that is for cooking. The terminal of the biogas is a small stove set up separately in the kitchen of each household, this stove is specially made, and it is also a project that starts with the water plant, faucet, flush toilet, and material pool, all of which started after Sima Pianpian knew the role of these two functional spaces, and has not yet been popularized, and will definitely be in the future. The special feature of this stove is that it has a valve, and when it is opened, a light blue flame will appear on it, and the pot can be used to cook vegetables, which is very convenient.

Of course. Biogas is not only used for this purpose, but Sima Pianpian is a lazy person, she is too lazy to study in depth in this area, and when the time comes, she may tell the primitive people about the relevant knowledge, if they are interested, they can study it themselves.

Whether it's her system, or all the functional spaces and those products, it's a symbol of convenience and, moreover, super-civilization. However, there are pros and cons to everything, and the sudden arrival of supercivilization from primitive to super-civilization will inevitably shorten the process of human beings developing civilization themselves. It reduces the opportunities for human beings to explore and grow on their own, much like pulling out seedlings to help grow, primitive people have not yet known the role of gasoline fuel, nor do they know how to make cars, they have already got on the bus, so to speak. It's ridiculous, so to speak, the history of mankind, lazy.

Well, it's her fault, but, without these functions of hers, primitive people don't know how many tens of thousands of years it will take to develop to enjoy these, no matter what the future holds, at least for now, everyone's life is good, and the Canglong civilization has also developed, and in the future, everyone will live a good life while learning and studying those basic substances, laws and principles, etc., isn't it?

Moreover, who said that human beings must only depend on material things for production and development? Don't forget, this is another world, different from the earth, the biggest resource here is spiritual energy, maybe one day, human beings can learn to use this energy like using gasoline, electricity, and minerals? Aren't the features and products she has now a good example of that?

The most important point is that Yuanzhu is creating a world that only belongs to her, and what will happen in the future, Yuanzhu must have its way......

The use of biogas is the same as water, it is also necessary to go to the biogas factory to recharge, the unknown space biogas capacity is also 1 million cubic meters, the family's biogas fee is 200 points per cubic meter, you can also zero calculation, that is, 1 point 5 cubic decimeters, how much to charge, the space will be automatically connected to the recharged pipeline, every time you open the valve of the stove, pure biogas can be used in cooking.

The use of biogas has reduced the consumption of countless firewood for the Canglong tribe, as well as reduced air pollution and the treatment of organic pollutants, which Sima Pianpian is very satisfied with.

Subway, tap water and biogas, these three functions, for the life and work of the Canglong people living in the super city provides great convenience, it can be said that it is the most basic function, so early appeared, it is really good, Sima Pianpian felt, this may be Yuanzhu is helping her to promote, want her city to be as stable as possible, on the right track as soon as possible.

At the same time, she also found that Yuanzhu seemed to be much more active than her in the development of the Canglong civilization, and when she had been thinking about running out to look at other areas and looking for that power, it had been signaling her to steady and develop ......

The matter of saving people or not is basically the same as what she explained to the clansmen on the radio last time, but she didn't mention Yuanzhu, and her intuition has always been biased towards letting her develop the tribe steadily, even if she has accumulated a lot of group spiritual power and can already use some advanced skills, it still hasn't wavered, which makes her feel a little puzzled, Yuanzhu doesn't seem to want her to save people, why?

Don't want her to take risks now?

Or does it already have another way?

Or is it both?

She doesn't think that Yuanzhu wants her to give up saving people, although she doesn't fully understand Yuanzhu, but she seems to vaguely feel that she understands something, just like a person understands her bottom line, she never gives up her bottom line, she believes that Yuanzhu is too, so, why?

Her instincts told her that in a short period of time, she would probably not be able to know the answer...... (To be continued.) )
