The Land of Wind possesses the largest territory in the Shinobi World, but ninety percent of its land is desert, with only a few oases suitable for human habitation.
As for plants... except for cacti, which have evolved special fleshy roots and stems to adapt to the dry environment and climate, other plants basically cannot survive in the desert.
To transform the desert environment through afforestation, one can only start little by little from near the oases.
Through the growth of plant roots and stems, gradually changing the geology outward.
But the vast area means that if ordinary people were to do it, it would probably require the persistent efforts of the entire population of the Land of Wind over several generations to see results.
If any mishaps occur midway, decades or even centuries of effort could turn to naught.
Even the First Hokage would be of no use here.
Even if he used his immense Chakra to quickly plant vegetation across the entire desert, in such an environment, the plants would soon die, failing to serve the purpose of changing the geology.
Therefore, trying to change the Land of Wind's environment through afforestation is undoubtedly a fool's dream.
But if one fuses White Zetsu's cells with Sage cells, then conducts in-depth research to transform them into rapidly growing plant seeds, and has the citizens plant them near towns in their spare time...
That could greatly shorten the transformation time.
Through calculations by the observation instrument, Ryuji estimated that, under the premise of reasonable planning and smooth progress, results could be seen in roughly twenty years.
"Fusing the cells themselves isn't difficult, but once fused, they become saplings, which would increase transportation costs..."
After pondering for a moment, Ryuji decided to create an inhibitor.
Since they are meant to be used as seeds for planting, let's call them seed cells.
Use an inhibitor to suppress the vitality of the Sage cells, so as to prevent the seed cells from immediately turning into saplings.
The inhibitor's effect could be set to automatically expire over time, or it could be designed to deactivate after being buried in the soil and receiving nourishment from the earth's vitality.
In short, it's about setting a timer for the seed cells.
As for which specific type to make, it depends on which is lower cost and higher efficiency.
As for how to make the inhibitor...
This is too simple; many poisons have life-inhibiting effects. One just needs to pay attention to the compatibility and dosage of the poison with the Sage cells to avoid immediately killing the cells.
But Ryuji knows nothing about poisons.
"This project will have to wait until I can consult Granny Chiyo later. After all, it's a large-scale project with a timeline of decades; there's no rush." After a moment of contemplation, Ryuji made a decision.
Although he could also seek help from other puppeteers,
But firstly, his relationship with those puppeteers isn't at that level; he doesn't want them knowing about his experiments. Secondly, those puppeteers' expertise in poisons is far inferior to Chiyo's.
Even though it's just making a vitality inhibitor and doesn't require extraordinary skill,
But people always tend to want the best and most powerful.
Otherwise, why did so many people in his previous life, with just a minor cold, go to top-tier hospitals to see specialists?
It's precisely this mentality.
…
The Sage Body creation encountered difficulties, and the seed cells also required consulting Chiyo.
With these two research projects temporarily shelved, Ryuji turned his attention to other projects.
Chakra Radar.
This was a project he conceived long ago, but due to the lack of Sensor-type Shinobi for reference, and later having more important research projects, it had been put on hold.
But now, after this setback, he felt it necessary to get this thing done first.
Why did his attempt to seize the Rinnegan fail?
He had long anticipated Madara coming to rescue Nagato and had prepared countermeasures in advance. Why was Madara still able to rescue him?
It was due to the intelligence disadvantage.
With a sufficiently large intelligence advantage, one could completely achieve a dimensional suppression against the enemy, to the extent that an ordinary person could effortlessly outmaneuver a Zhuge Liang.
Ryuji, through knowledge of the future from the original manga, could plan development routes beneficial to Sunagakure. Black Zetsu could manipulate Madara's entire life using ancient secrets. Madara could use one hundred thousand White Zetsu to observe the Shinobi World's situation and achieve his goals.
Because of the intelligence gap, Madara turned a situation originally meant to force Nagato to his death into one that forced him to turn dark, and even shifted the root of hatred onto Ryuji himself.
If he had detected the secretly watching Madara earlier, if he had known Konan was among the fleeing crowd, he wouldn't have made the decision to send his subordinates to pursue.
Everything boils down to intelligence.
Therefore, he must complete the Chakra Radar as soon as possible.
At the very least, ensure there are no White Zetsu monitoring his vicinity.
…
Days spent immersed in research always pass quickly. Unconsciously, a week had gone by.
During these seven days, the development of the Shinobi World's situation unfolded just as Ryuji predicted.
After Konoha eliminated the three-thousand-strong Iwa-Kusa alliance in the Land of Rice Fields, the Allied Forces of the two villages on the Land of Grass's front breached Konoha's defense line the next day.
By the time Konoha's forces from the Land of Rice Fields arrived, they only managed to gather less than two thousand surviving Genin remnants.
This was the result of Orochimaru, seeing the situation turning bad, ordering a swift retreat.
If they had fought to the death, they probably would have been completely annihilated.
The final outcome became the predicted seven thousand Kusa-Iwa allied forces versus Konoha's five thousand.
And Kirigakure, after three consecutive failed attacks, abandoned its surprise assault on the Land of Wind.
Pakura's performance in this war was too formidable; the name 'Scorch Release Pakura' began to spread throughout the Shinobi World.
The Third Kazekage's conditions for war reparations from Amegakure were also settled on the fourth day.
All the Chakra Metal that Hanzo and his people plundered from the Land of Iron became Sunagakure's possession.
Although Amegakure initially absolutely refused to agree to these extremely harsh demands, as the Third Kazekage's patience gradually wore thin, the Sunagakure's army outside the village grew restless.
In the end, the leaderless Amegakure still agreed to these humiliating conditions.
The expeditionary force returned to Sunagakure at noon on the sixth day.
Round Table Conference's members and a large number of villagers came out to welcome the victorious Shinobi, and for a time, the entire Sunagakure was immersed in a celebratory atmosphere.
But this was only superficial.
Three thousand troops set out; eighteen hundred returned. Over a thousand families lost loved ones.
Beneath the celebratory surface lay the hidden pain of lost relatives.
That night, Ryuji heard faint sounds of weeping carried by the wind and sand.
The sound was hard to bear, so he buried himself in his workshop for research.
Over these many days, his research had borne fruit.
By understanding the principles behind Kuro's perception, imitating his brain structure, he created a biological perception brain.
Its perception range was only slightly less than Kuro's.
However, what Ryuji wanted was a Chakra Radar capable of detecting White Zetsu, not an ordinary sensor.
Plus, this thing was the size of three basketballs, inconvenient to carry, so it could only be considered a semi-finished product.
He planned to continue research, optimize it, shrink the sensor's volume, then mechanize it and make fine adjustments specifically for White Zetsu's Chakra to complete the final stage.
But semi-finished products also have their uses.
Sunagakure lacks a perception network, making it difficult to guard against enemy infiltration.
Although the biological brain's perception range cannot cover the entire village, signal towers can be constructed in multiple locations, connected via the Sea of Consciousness, projecting images onto screens.
Of course, using the biological brain requires Chakra.
If this perception network were to be built in Sunagakure, individuals would need to be specifically assigned to provide Chakra.
But considering that the Mechanical City will be completed in six years… no, the war reparations from Amegakure can accelerate construction by two years, so it will be ready in four years.
Therefore, Ryuji doesn't plan to waste effort and money building this in the current Sunagakure. Instead, after the Mechanical City is built, it will be directly used there.
With the Dragon Vein, there's no need to worry about Chakra Supply.
With the energy supply problem solved, the next consideration is security risks.
This thing is made based on the perception principles of Sensor-type Shinobi. Unlike Konoha's perception network, which only senses the village borders and entrances, this can peer into every corner of the village.
As long as one is within the village, everyone's location can be sensed at all times.
Such an intelligence super-weapon… whoever masters it can grasp the location of everyone within the village; no one can keep secrets from them.
This super-weapon must be controlled by someone absolutely trustworthy.
But where in the world is there an absolutely trustworthy person?
Even if Ryuji creates a puppet with a long lifespan, after his death or if he leaves Sunagakure for too long, the puppet's thoughts would change based on its experiences, let alone other people.
If this thing falls into the hands of an enemy spy, it would be like checkmate.
After repeated consideration, Ryuji decided to create an emotionless artificial intelligence.
Of course, not an AI in electronic data, but an artificial soul, like Jarvis from Iron Man.
With protecting Sunagakure's safety as the core directive, supplemented by detailed regulations like preventing infiltrators, stopping and combating criminal incidents for programming.
Once the AI is created, it will interface with relevant departments.
For ordinary civilian's security issues, it will report to the police force; if infiltrators or spies are detected, report to the Anbu; if there are conspiracies of rebellion within the village, report directly to the Kazekage and the Round Table Conference.
Additionally, to avoid a scenario where the AI evolves, ultimately becoming a boss like the Red Queen in the 'Resident Evil' movies, destroying Sunagakure due to logical contradictions, Ryuji will install a daily factory reset function on the device carrying it.
Of course, even with a daily reset function, the smaller the risk, the better.
Avoiding risks at the source is the best approach.
Therefore, Ryuji hasn't started programming yet.
He plans to wait until the Mechanical City is built, then invite professionals familiar with various fields to conduct investigations and research based on the Mechanical City's actual conditions, providing the most suitable suggestions for programming.
He aims to make this perception network a sharp tool serving the Mechanical City, not a Damocles' sword threatening himself.
So, the perception network project is also temporarily shelved.
Afterwards, Ryuji didn't continue other research projects but went to Roran.
Because the foundation excavation for the Mechanical City was almost finished.
