After eating, Yubi had a wonderful sleep.
The next day, he went to the Village's administrative office to record the Ninjutsu he had developed into a scroll.
Afterward, he headed to the Village hospital.
Because it was the Second Great Ninja War and the timeline was quite early, the public infrastructure of the Five Great Ninja Villages—including Konoha—was still relatively simple and far from as complete as it would be during Naruto's era.
At this time, the hospital in the Hidden Sand Village was not large, and its internal environment and decor were quite ordinary.
As a Medical Ninja who had interned at the hospital before, he could enter and leave the premises freely.
Aside from treating Ninjas, the hospital's primary function was actually to look after the health of the Hidden Sand Village residents. However, because it was a special period, almost all the patients in the hospital were Sunagakure who had withdrawn from the battlefield; there were hardly any civilians.
All the doctors and Medical Ninja were so busy their feet barely touched the ground... there weren't even any spare beds.
Many Sunagakure were lying on straw mats, waiting for treatment.
Moreover, those who had returned from the front lines... at a glance, they were all heavily injured.
There were no light injuries.
Yubi quickly threw himself into the rescue work.
Although treating patients in the hospital didn't have the battlefield buff, and the experience points gained were relatively limited... even a mosquito's leg is meat; it couldn't be wasted.
In the process, he could also practice his Medical Ninjutsu, which was helpful for his Chakra cultivation.
Even if the workload in the hospital wasn't as heavy as on the battlefield, it was still significant. After a busy day, it was already late at night by the time he returned home.
He didn't even have time to eat a meal.
"The Village's funds are tight right now... there's no way to invest in public facility construction. Almost all resource reserves have been consumed by the war." Lying in bed and listening to his stomach growl, Yubi's thoughts were elsewhere.
Today, his presence had been a huge help to the hospital and relieved a lot of pressure.
It also made many of his colleagues very grateful to him.
Setting aside the Medical Ninja aspect, in terms of pure surgical skill, Yubi—who had inherited Kuroo's abilities—possessed medical knowledge and insights that people of this world couldn't compare to. The medical skills of the people currently in the Sunagakure hospital were still relatively backward.
"I've had this idea for a while... but the timing wasn't right before. Now, I can start the second step..."
Yubi said softly. On the third day, Yubi went to find Grandmother Chiyo.
He voiced his thoughts.
"Teaching?"
"Yes... I want to train some doctors with outstanding abilities for the Village. I don't mean Medical Ninja, just pure medical treatment and nursing. Additionally, there are some specialized tools for surgical operations that are currently missing. I want the Village to manufacture a batch; it won't cost much... but it can greatly improve our Hidden Sand Village's medical capabilities. At the same time, it can increase the survival rate of the Village's Ninjas, which will be very helpful for this Ninja World War."
Yubi said with a smile.
"..."
Chiyo fell silent.
Yubi was a genius; the Village had already certified that, it was true.
And on the battlefield, Yubi had also shown impressive medical rescue capabilities.
But one thing was one thing... no matter how outstanding Yubi was, he might not necessarily surpass the veterans in the hospital by much.
An eight-year-old child... suddenly saying he had the ability to improve the hospital's projects... Yubi had come to Chiyo because Grandmother Chiyo was the main person in charge of the Village's Medical Department.
As long as she nodded, there would be no problem.
"We can give it a try... You can audit it, Grandmother Chiyo. I can teach one or two people first. If you're not satisfied, just act like I never said anything." Yubi knew that in Grandmother Chiyo's eyes, what he was doing seemed a bit like acting out.
But considering his relationship with Sasori... plus the fact that if this succeeded, it would definitely benefit the Village.
There was nothing to lose by trying.
"Fine."
Chiyo's hand holding the teacup slowly relaxed.
Ultimately, she agreed with a smile.
Geniuses... they should have a few small privileges.
In her view, Yubi was still immature at this age. Moreover, the praise he received after returning to the Village this time might have caused the little brat to lose his way a bit, making him unaware of his own limitations.
Through this matter, she could make Yubi realize his own shortcomings—that even a genius... cannot do everything.
This was also a good thing.
It could temper his arrogance and help his future growth.
With Chiyo's approval, Yubi immediately got to work and entered his working state.
After entering the hospital, his task was no longer simple treatment... but gradually explaining his surgical steps and logic to the people accompanying him.
At first, the group of veterans in the hospital felt very uncomfortable following a little kid to listen to lectures, but since it was Chiyo's order, they had to comply. However, as time passed, people gradually realized that Yubi's teaching wasn't nonsense... it was backed by clear thinking and a wealth of knowledge. This kind of ability required a massive accumulation of medical experience; it wasn't something one could grasp simply through study.
For the same type of case, after using Yubi's treatment plan, the efficiency was indeed higher, and the patients recovered better.
This didn't even need auditing, because the improvement in the hospital staff's abilities was visible to the naked eye. During the day, Yubi immersed himself in the hospital; at night, after returning home, he had to hand-write a large amount of medical materials for the hospital staff to study.
These were only a small part of Yubi's knowledge base. The medical content he taught was tailored to the specific situations of the Sunagakure who needed treatment and the integration of major injuries during wartime, rather than everything.
But even just these were of considerable help to the Sunagakure Medical Department.
Yubi stayed in the hospital for three months.
Towards the end, even Grandmother Chiyo was reluctant to let him go... she even personally came to the hospital to learn some of Yubi's medical concepts like everyone else.
A Village is neither too big nor too small.
The Sunagakure returning from the battlefield received excellent treatment, and the personnel and capacity for the Village to subsequently support the battlefield were given the best care... this also greatly reduced the secondary loss of the Hidden Sand Village's combat power.
Furthermore, a Village is neither too big nor too small... every Ninja cured in the hospital was connected to a household.
Thus... very quickly, the entire Village knew of Yubi's existence.
This genius 'Little Divine Doctor' had not only solved the 'pain point' of the Village's combat reserves but had also saved many families.
And this... was exactly the 'prestige' Yubi needed.
To put it plainly, it was about winning over people's hearts.
He didn't care how dazzling his talent was... or how many incredible things he did in the eyes of outsiders.
He wanted the Village's higher-ups to realize his importance.
The more important, the better... to make the Hidden Sand Village understand that they couldn't do without him.
Of course, everything Yubi did had only one purpose.
And that was... to sit in that position!
As a transmigrator, Yubi knew one thing very well... while the Ninjas in the Village shed their blood on the front lines, the civilians living a comfortable life in the rear didn't see those merits and glory with their own eyes, nor did they have a direct understanding of them.
To them, what was more important were the things and changes happening right around them.
What Yubi wanted was his own reputation and image... this was actually quite unfair to those who wanted to rise purely based on military merit.
But there was no helping it... that was reality.
