What restricts the development of the Wind Country is the lack of fresh water.

Luo Sha, the former Fengying Fourth Generation, could not understand this problem.

But it is another thing to know whether it is one thing, but whether it is capable of solving it.

Before Dawan found a way to prepare fresh water, the water in Sahimura was more expensive than oil. This "oil" was still a very precious cooking oil, not kerosene used for ignition and lighting.

Only after the large-scale "multi-level flash evaporation" seawater desalination plant in Awaji Village in South China Sea area did the water cost of residents begin to decline. Even so, desalination seawater with salty smell and lingering coal ash flavor is still a valuable resource that requires careful calculation.

Drinking water is the first level, followed by kitchen waste water, washing water, and washing and cleaning water. This second level cannot be poured out, but must be concentrated and recycled by the urban management department. It is used as an industrial water with less demanding requirements. At this point, it enters the wastewater recycling system and uses the increasingly mature multi-stage flash evaporation technology to purify and cycle.

Finally, high-pollution concentrated wastewater with no utilization value is stored in fermentation tanks, and finally used as irrigation of sand fixing vegetation and drip irrigation in experimental orchards and vegetable gardens.

Saving water is almost the instinct of the residents of the Wind Country, and the village managed by the Sand Ninjas also maximizes this tradition.

In the early stage, all kinds of fruits and melons in Awaji Village were not directly consumed except for a few gardens. Instead, they had to be fermented or detoxified and made into wine, juice or canned food for sale.

The irrigation water is not clean, and the fruits and vegetables produced in the fields are more or less affected, and the land is accelerated to be salinized, casting a shadow on the development of Awaji Village.

Improving the quality of seawater desalination water and increasing output is also the top priority, and the need to cultivate alkali-resistant crops and plants is also imminent.

In the central part of the Wind Country, with melted water supply on the plateau snow peaks, the demand for freshwater is still strong in the coastal areas, so Damaru turned his attention to a more intelligent and effective reverse osmosis method than "multi-level flash evaporation".

There are two difficulties in removing minor details.

The first is a stable high-pressure environment. Originally, Sand Village did not have such conditions. Whether it is materials, technology or mechanical equipment development, they were much worse. However, with the giant reincarnation eye brought back from the moon, which can provide a fine and sufficiently powerful pressure field, this problem is solved.

The second is an efficient, reliable and cheap reverse osmosis membrane. This is the real difficulty. Damaru's most advanced material technology in his previous life cannot take into account efficiency and cost. Today's ninja world is even worse. Not to mention the reverse osmosis membrane that can turn seawater essence into fresh water, even ultrafiltration membranes with macromolecular impurities below 100 nanometers cannot be produced, and at most solid materials below one micron can be intercepted. At this level, let alone filtering inorganic salts in seawater, even smaller large molecular proteins, colloids, bacteria and suspended substances are not much better than activated carbon.

Therefore, Damaru has never used this kind of seawater desalination technology, which has many benefits but is really not low in technical content.

Fortunately, a while ago, an unexpected discovery gave Damaru an inspiration.

Members of the Sand Village air combat troops who cleared pirates in the South China Sea conducted a detailed investigation into the distribution of major islands and ocean currents. They accidentally found several species of seagulls, albatrosses and sea mammals that actually swallowed seawater and pressurized them to filter fresh water in their bodies.

In other words, the miracle of nature helped these natural creatures to evolve efficient and reliable reverse osmosis membranes.

It is precisely because of such "magical skills" that these creatures born from the sea have never worried about insufficient drinking fresh water.

Damaru was extremely surprised to learn about this and entrusted his subordinates to conduct a more detailed investigation, and even asked several "artificial elves" to take turns to observe the matter, confirming the authenticity of the matter, and even found that several major species had similar functions.

The organs they evolved with reverse osmosis membrane functions are different, but one thing they have in common is that they can drink sea water directly without dying of thirst, and can also replenish fresh water and maintain body fluid balance.

The industrial level is not up to date, but the bioreverse osmosis membrane is ready-made. The only trouble is that those marine organisms are not enough to kill. Even if they are caught and "take materials", cut off crops, fish bladder, lung conjunctiva, etc., it is not enough to build a super-large seawater desalination plant.

At this time, the advantage of the ninja world with extraordinary power came. Industrial products, such as cellulose carbonate, polyamide, etc., Damaru probably won't be able to create it for another twenty years after research. However, with ready-made biological samples, puppet and ninjutsu enhanced versions of biological cloning technology can come in handy.

Damaru, who was upset and sighed about why he had never expected before, quickly ordered his subordinates to speed up the relevant research and experiments. In Naruto Village, a small-scale reverse osmosis and pressurization method seawater desalination base has been trial operation for a week, and no accidents have occurred.

With the first mature experience, I have spread all the way along the coast of Wind Country and combined with the snow melting water in the middle of Wind Country, it can basically meet the water use of the entire country.

The envisioned scenario is that the reverse osmosis method is used to prepare high-quality fresh water, and the multi-stage flash seawater desalination plant is committed to wastewater recycling and industrial water with low requirements.

Because of this, Damaru's attitude towards the giant reincarnation eye has also undergone tremendous changes. His purpose was to let it go after it was used. As a result, he found that this powerful energy source and power generator that can almost maintain the operation of a satellite is itself an inexhaustible treasure house.

"It's really a waste to use the giant reincarnation eye to fight. This is a biological version of the "semi-permanent motion machine"!"

The experience of the previous life has helped Damaru a lot and brought deep-rooted prejudice. There are still many blind spots in the combination of ninjutsu, chakra and blood transcendence boundary and natural technology, ignoring truly valuable treasures.

Because of this, I originally thought that I could only make a three-pointer with no dates, but I had the intention of making a profit if I had achieved results, but now I am very serious about finding the secret.

The Otsutsuki clan and the sacred tree are extraordinary creatures that truly transcend common sense. The true value of their body needs to be discovered carefully.

For example, Daimaru used all his skills to get a Sharingan, and then grabbed the two-tailed genital Riki Yukito, and handed over the "vote letter", Uchiha Obito paid the "final payment" of another Sharingan.

Together, they are a pair of three Tome-Da-Sharingans. Daimaru doesn't know who his original owner is, and most of them are not an unknown person in the Uchiha family.

But these are not important, and how to use them is the top priority.

The possibility of transplanting it into other people's bodies and opening the Maneid Sharingan is basically zero. Such a blood-resistance limit is not very useful to the current Damaru.

One of the ways Daimaru could think of was to use it as a material for the reincarnation of the filthy land, and to summon the soul of the psychic from the Pure Land to become a filthy land body.

However, such a risk is too great and it may not be successful.

The general method is useless, so you have to think of some special means.

If you do it completely out of thin air, Damaru's imagination will be ineffective, but it is still possible to learn from "ready-made" examples.

For example, the one that was used as an excellent material by Orochimaru, even transplanted an arm covered with Sharingan to give to Shimura Danzo, which has the perfect carrying capacity.

It is still unknown what that guy with special abilities will become in the future. Damaru already has cell samples in his hand, and even a few clones with ignorant and ignorant clones. At the same time, it is also used as a modulation "material" and is used in several special biological puppets, and the effect is quite good.

When such an experiment was not conducted, Daimaru was particularly envious of Orochimaru's talents and his right-hand assistant.

After receiving the news that a puppet test work collapsed because it could not withstand the erosion of the Sharingan, Daimaru, who was far away in Konoha Village, had to temporarily stop the futile attempt.

"There has been too much accumulation recently. We need to calm down, sort out the gains and losses of the results, and then consider the next step..."

As the "big sister", Xiao Shanchui ran around and was busy, and had to direct a few sisters to arrange the tasks assigned by Damaru. He was really exhausted.

In his spare time, while fiddling with several highly toxic pets he raised, he echoed with some distractedness:

"There are many things on my mother's side, and Jin was also called to deal with it..."

"Is that true!"

Miss Shaye didn't hear anything happening for a while. Daimaru recalled it and seemed to find no problem, so he put it down for the time being. Then he remembered something and asked,

"Honglian... isn't she working diligently? The crystallization, debugging and installation of bioreverse osmosis membranes require her blood limits. If the chain is dropped, it will be bad. It's a small matter to affect the progress. Those biofilms will fail if they are exposed to the air for too long..."

"Don't worry!"

He clapped his hands happily, blew up to the hill where the pets had finished feeding, and replied confidently,

"Although the blood limit of that big sister's blood limit is very useful, the chakra and physical strength are far from keeping up with the needs. Fortunately, Bai Jue clone provides support and various supplies such as military rations, so she barely dealt with it..."

"That's good. Don't have problems at critical moments. So many 'new immigrants' are pouring in. If there is a problem with drinking fresh water, it will be troublesome..."

Daimaru nodded with satisfaction,

"What's wrong with Gaara?"

"Well..."

Xiao Shanbu climbed up Daman's shoulders skillfully, kicked his calves back and forth, and said in a low voice,

"The Five Dynasties seem to be more repulsive of those rituals and pomp..."

"It's normal, as long as he's patient to finish it..."

A boy of fifteen or sixteen years old is the most rebellious age in his life. Although Gaara seems calm because of his childhood experience, he is still a little naive.

In the village, even Fengying is nominally just a special upper ninja. There is a relationship of superiors and subordinates between ninjas. In the entire human society, it is actually at the same level. They are all "civilians" without ancestral honors and reputations. In secular society, it is equivalent to being strong everywhere. However, the ninja village is too strong, and even Daming and the government have to look at each other.

But now it’s different. Gaara is both the village chief of Fengying Five Dynasties and the village of Sakai Village, and also the Great Imperial Office, a noble and an official.

People in peaceful times probably cannot understand the strict class society and respect for the status of aristocrats. Even if they shouted "Whether kings, princes, generals and ministers are more likely to be borne by them", the people at the bottom are not resisting the nobles themselves, but by one family, controlling reputation and authority without sharing them with others. The purpose of overthrowing the nobles is to make themselves aristocrats, which is definitely not for the ideal of being equal to everyone.

In the ninja world, civilians who have little knowledge have deep obedience and awe for nobles who have great righteousness.

Like Gaara, Tsunade, Hinata family and Uchiha family, at most half a nobleman, who is real but not famous. Today, the Fogchae Five Dynasties is considered a name-and-real person.

How can we let others know that Lord Fengying in Sand Village is different from before?

Of course, strength is the top priority, but you can’t meet anyone with questions and beat him up to show your prestige?

Therefore, the importance of systems, rituals and pomp is highlighted.

In the past, the Shirokage House, basically all the innocent Satsuki Ninjas could go to see him. For example, Daimaru, more than three years ago, in order to allocate the team and qualification for the Chuninian exam, he went to find Rasa who had been the Shirokage at the time. Of course, it was another matter to see Shirokage, but at least, everyone has this right, but they wouldn't do it if they had nothing to do.

But now it is not possible. The flat-scale management has become a more rigorous, complex and hierarchical bureaucratic system. Nowadays, ordinary civilians have not been summoned. If they want to take the initiative to meet Gaara, they have to go through at least three reviews. In the past, Daimaru just asked the guard to pass on a message, and after agreeing, he saw Fengying.

The travel and formal occasions of the Dayu Temple are so strict that Gaara cannot accept it, which is somewhat contrary to his previous image as a village chief who is close to the people.

Unfortunately, this is a necessary way to integrate into the traditional secular power order of the world. The frivolous acts that were in harmony with everyone in the past were probably rarely done. They separated from the interests of the general public and opened up the distance between ordinary villagers and brought prestige.

"It's good that he can get used to it. In addition, the progress of the village taking over the southern coastal areas of Sichuan Country has accelerated! By the way, the fragrant wine went to take over, and that kind of ghost place was rampant. I don't know how many plagues were raging. With him, he could have a lot of energy left..."

"Kawa Country? By the way, Uchiha Sasuke seems to have appeared at the junction of Fire Country and Kawa Country..."

"Um?"

Daimaru was stunned,

"Is Uchiha Itachi also there? That's interesting..."
