Hearing Uchiha You's seemingly casual words, Uchiha Bu Shi was startled and asked, "Brother You, do you know this person?"

Uchiha You said unhappily: "You idiot, if I don't know them, how can I assign you to investigate?"

"Uchiha Obito is a member of our clan, the orphan of the previous generation of elders, so the clan leader gave me a task when I was still a Chunin, asking me to teach him ninjutsu."

"However, when I was on a mission, I found that Uchiha Obito's basics were too poor, so I forced him to do basic training for several days, and finally taught him a few commonly used ninjutsu."

Uchiha Bu Shi thought for a moment and asked again: "From the tone of my elder brother, it seems that he is more familiar with Shinichi."

Uchiha You said helplessly: "Uchiha Obito is a weirdo. My mission was to teach him, but he insisted on taking his teammates with him and using my time and energy to fulfill his kindness."

"So I trained him pretty hard, but I also discovered that his teammate Shinichi was a pretty good ninja, so I taught him some real skills, and we became friends."

Uchiha You smiled and asked, "Ayumi, aren't you curious about why I am so tolerant of Obito?"

Uchiha Ayumi immediately replied: "Curious, Brother You, I really can't understand why you pay attention to Obito. Although his personal strength is good, this 'weirdo' you mentioned is really a waste that drags people down."

"I haven't even left the village yet. With a simple investigation, I can find out that he has dragged down his teammates more than once. From those lines of text, I can feel Shinichi's distress."

"If I were the ninja named Shinichi, I would smash Obito's mouth."

Uchiha You looked around and noticed that there was no one around, and whispered: "Uchiha Obito is one of the two people in the family with the most potential and the most likely to awaken the Mangekyō Sharingan."

Hearing Uchiha You's words, Uchiha Ayumi's pupils suddenly dilated, his mouth slightly opened, and after a while he asked: "Brother You, what is the Mangekyō Sharingan? Is it a special Sharingan?"

Uchiha You turned around suddenly, his eyes slightly widened, looking at his most loyal younger brother, hesitantly asked: "I didn't tell you what the Mangekyō Sharingan is?"

"No, this is the first time I heard this name."

"..., well, you are the person I trust the most, so I will tell you."

However, Uchiha You did not speak directly. Instead, he blinked his eyes, opened his three-magatama Sharingan, looked deeply at Uchiha Ayumi, and pulled him into the illusion.

When Uchiha Ayumi realized that he was in the world of illusion, he couldn't help swallowing, because he was sitting on a hard chair with a backrest and in front of him was a desk with a drawer that was only 75 cm wide.

This is the most terrifying nightmare, the standard setting for studying for exams in dreams. Just sitting here is enough to make the Uchiha brothers tremble with fear.

Each of them had a nightmare, sitting on this set of desks and chairs, being forced to study extremely hard. The inhuman process of studying so hard was so painful that they felt like dying just thinking about it.

However, Uchiha You appeared in the illusion world and explained to Uchiha Ayumi: "What I am going to tell you is a secret. Currently, only Konoha Village and the Uchiha family leaders know about it, so I choose to tell you in the illusion."

Hearing the familiar words, Uchiha Bu Shi immediately felt relieved. He immediately nodded and said, "I will keep it a secret, Brother You."

"Well, I believe you."

Uchiha Yuu began to narrate: "I learned about the existence of the Mangekyō Sharingan through ancient books and manuscripts in the family's collection room. According to the records of the family's predecessors, the Mangekyō Sharingan is called the 'strongest eye that sees through the three realms', and the Mangekyō pupil technique is the 'earth-shaking pupil technique'."

"In short, the three-magatama Sharingan has another breakthrough, which is the Mangekyō Sharingan. But the difference in pupil power between the three-magatama and the Mangekyō is huge. The Mangekyō can deal with the three-magatama more easily than the three-magatama can deal with ordinary people."

"Moreover, once the three-magatama Sharingan is awakened, different patterns will appear for each person, and completely different exclusive eye techniques will be obtained, so it is called the Mangekyō Sharingan."

In the illusion world, Uchiha You cooperated with the display of the pictures and told Uchiha Ayumi the origin of the Mangekyō Sharingan.

From the Six Paths Sage Ōtsutsuki Hagoromo who developed the Sharingan, to the Sage's eldest son Indra who inherited the Sharingan, the bloodline was passed down all the way to form the Uchiha clan.

Talking about the traditional way of awakening the Mangekyō, as well as Uchiha Yu's own awakening method that he has figured out but has not yet tried.

He also talked about the disadvantage of awakening the Mangekyō Sharingan, which would cause blindness as it is used.

During this lecture, Uchiha Bu Shi listened attentively throughout. Only then did he know that the origin of the Uchiha Family was so profound and it turned out that his ancestor was the Sage of Six Paths.

Uchiha Ayumi's pride suddenly grew stronger and he felt very confident.

But when he heard that after awakening the Mangekyō Sharingan, one would inevitably go blind, although he felt that he might not be able to awaken the Mangekyō Sharingan, he couldn't help but feel a chill in his heart.

So Uchiha Bu Shi couldn't help but ask: "Why did he go blind? He clearly awakened a more powerful Sharingan, why did he go blind?"

Uchiha You replied: "There are two reasons. First, the Mangekyō Sharingan is not complete enough. Second, the awakener himself is not strong enough."

"Ayumi, you may not know that the previous clan leader, Uchiha Madara, was further perfected by fusing his younger brother's Mangekyō."

"Not only did he solve the problem of blindness, but he also became even more powerful, known as the Shura of the Ninja World."

"Uchiha Madara's Sharingan is called the Eternal Mangekyō Sharingan."

The boss Uchiha Bu Shi opened his mouth and murmured, "Brother, I don't know anything about what you said. Is someone hiding the truth? What do they want to do?"

Uchiha You said: "It's not a deliberate concealment. Uchiha Madara and the first Hokage jointly founded Konoha Village, but he later changed his mind and became the first rebel ninja in Konoha Village."

"For the Uchiha clan and the entire Konoha Village, this matter is extremely embarrassing, so they are intentionally or unintentionally avoiding Uchiha Madara's name. As time goes by, we, the new generation of ninjas, naturally don't know about it."

"In short, this is the only effective solution known so far. Unfortunately, most of the ninjas of the Uchiha family are destined to be unable to meet this condition."

Uchiha Bu Shi smiled and said, "Yes, my elder brother and I are both orphans without brothers. We are born unable to follow this path."

"Brother You, what about the second way?"

"The second path is what I guessed based on the two people at the source of our bloodline. The Six Paths Sage and Indra both have Sharingan, but I've never heard that they need to awaken the Eternal Eye."

"The difference between these two ancestors and us is only the purity of their bloodline and the huge difference in strength."

"We don't have brothers to make up for the difference in blood purity, but we can become stronger through practice. No matter how big the gap between us and our ancestors is, there is hope as long as we become stronger through practice."

Uchiha Bu Shi suddenly said, "But such a huge gap cannot be made up by ordinary training methods. Brother You, can you teach me the real training?"

Uchiha You looked at his younger brother in surprise. Bu Shi was obviously not the smartest, but he was decisive at the critical moment.

Also seriously injured, Uchiha Ikki couldn't control himself and awakened the three-magatama Sharingan in one breath. From then on, his upper limit was locked on the Mangekyō Sharingan, and it came with an abnormal state that made it easy to get out of control.

Even though Uchiha Ayumi lost his legs and hands, he was able to keep his emotions stable and insist on walking on Uchiha Yuu's path.

And now, before Uchiha You even mentioned teaching him the magic, Uchiha Bu Shi suddenly had an idea and took the initiative to make a request to him.

This is no small matter.

When asking for help, you should first step in, help others solve the problem they are asking for a hand, and bear all losses incurred by their help.

The most taboo thing is to ask others for help, but stand on the dry shore and throw all the responsibilities and consequences to others.

Of course, what is even worse is to stand on the moral high ground and use the weapon of moral kidnapping to force others to help, forcing people into a desperate situation from the very beginning.

Uchiha Ayumi's active request handed over the initiative to him. Uchiha You taught him that he was no longer actively showing favors, but passively satisfying his brother's requests.

In this matter, the difference between active and passive is very subtle, but the difference in cause and effect is huge.

This is like the experiment of moving a single pendulum ball. All conditions are the same, but by unlocking the car body at different times, the car can move in two completely opposite directions.

Hearing Uchiha Bu Shi's request, Uchiha You suddenly felt relieved. He suddenly understood a little about the saying "Bodhisattva fears cause".

Uchiha You, who was in a good mood, smiled and said, "Okay, I'll teach you."

"However, from today on, you can no longer teach anyone anything I teach you without my permission."

Uchiha Bu Shi was overjoyed when he heard this. He nodded repeatedly and promised to keep it a secret.

Uchiha You did not teach the true method of cultivation in the illusion world, but continued to talk about the knowledge of the Mangekyō Sharingan, and finally talked about the ultimate power resided in the Mangekyō Sharingan - Susanoo.

Through illusion, Uchiha You demonstrated the power of Susanoo to Uchiha Ayumi, allowing him to truly experience the power that crushes all ninjas.

As long as Susanoo appears in the world, all the ninjutsu will be divided into two categories: one is the powerful ninjutsu that can threaten Susanoo, and the other is the useless ninjutsu that Susanoo is immune to.

Just as Uchiha Ayumi was blushing and scratching his ears excitedly, Uchiha You asked: "Now do you understand why I ordered you to investigate Uchiha Obito's intelligence?"

"I understand. If Obito has the potential to awaken the Mangekyō Sharingan, then it is only natural to value him no matter how much."

Uchiha Ayumi answered seriously, but he hesitated and said: "But Obito is obviously a idiot with some talent but a muddled mind. Why does he have such potential?"

Uchiha You immediately replied: "Based on his rich emotions and his unclear mind."

"Bu Shi, you were influenced by me and subconsciously thought that the traditional way of awakening the Mangekyo was wrong, so you made such a judgment."

"Now look at it from another angle. Who is the ninja in the Uchiha clan who has the most sincere emotions and the most intense mood swings?"

Uchiha Ayumi thought carefully for a long time before he said with difficulty: "Uchiha Obito..."

Uchiha You nodded, and then continued: "If you don't consider the identity of ninjas, and lower the age standard, who else can you think of?"

"Uchiha Shisui... Shisui brother? Oh my god!"

Uchiha Ayumi was extremely shocked, causing the fragile illusion space to be destroyed, and he and Uchiha You woke up instantly.

The continuous acquisition of important intelligence made Bu Shi feel dizzy. He looked at his elder brother, not knowing what to say.

Uchiha You patted his shoulder and ordered: "Just know these things yourself."

After being photographed, Uchiha Ayumi woke up instantly and immediately replied, "Yes."

"Also, in the next period of time, you will investigate the intelligence of the other two people. This time, I ask you to investigate more carefully."

"Brother You, who should I investigate?"

"One of the Three Ninjas of Konoha, Jiraiya's apprentice, Namikaze Minato, a jonin, and Hatake Kakashi, a chuunin, son of the White Fang of Konoha, Hatake Sakumo."

"I see. I'll start investigating right away."

"Be careful when investigating. Hatake Kakashi is a ninja that the Third Hokage focuses on, and Namikaze Minato Jonin himself is a very powerful ninja, so you have to conduct indirect investigations as much as possible."

"I will be careful, please rest assured."

"One last thing. Starting tomorrow morning, you must come to my house before dawn. I will teach you the real way to practice."

Uchiha Ayumi shouted excitedly: "Brother You, I will definitely not be late!"

…

Time passed quickly, and in the blink of an eye, it was the end of the 44th year of Konoha.

Since December, there have been several snowfalls in Konoha Village. The livelihood issues within the village have become serious, and the war pressure on the front line has also been increasing.

After a few months, the Sand Village, the Iwagakure Village, and the Cloud Village all breathed a sigh of relief. After adapting to the pressure from the Konoha Village, they began to be eager to fight back.

As Uchiha Ayumi's activities increased, when most people were used to the fact that he was a healthy ninja, some people finally connected him with the disabled person a few months ago.

As expected, as the Uchiha family confirmed this incident, it caused a huge sensation among the Konoha ninjas.

Thanks to Tsunade's efforts, the level of Konoha Village's medical ninjas is unrivaled in the ninja world. As long as the Konoha ninjas do not die in battle on the spot, they can save their lives.

Medical ninjutsu is amazing, but it is not omnipotent.

The medical ninjas were able to reattach severed arms and legs, but they were unable to regrow lost limbs.

Therefore, there are many ninjas in Konoha Village who had to retire because of missing limbs.

The number of these disabled people is so huge that almost every family in Konoha Village is involved.

The impact of this matter was so great that even Orochimaru and the Third Hokage had to personally inquire about it. In view of Uchiha Yu's identity and strength, two treatment quotas per month were finally determined.

And one of the places will be given priority to a ninja from the Uchiha family.

As a reward, Uchiha You can get a mission reward, and the level of the mission will be determined according to the level of the ninja being treated.

Treating a Genin is a C-level task, treating a Chunin is a B-level task, and treating a Jonin is an A-level task.

Uchiha You also asked at the time: "Although the Third Hokage is unlikely to be injured, what if there is a chance to treat the Third Hokage?"

Sarutobi Hiruzen laughed and replied, "Don't worry, the Hokage will of course be responsible for S-level missions."

However, the first two disabled ninjas selected were all Genin. It was obvious that they were test subjects to test Uchiha Yu's true level.

Then let's experiment. Uchiha You doesn't care. The only thing he has to do is to disguise himself well so that no one finds out that the limb regeneration technique is Wood Release.

In fact, this matter is very simple. You can use Wood Release to cultivate tree species to replace bones in advance, and use hand carving instead of ninjutsu shaping.

Finally, the volume of the plant at the regeneration endpoint is reduced, at the expense of reducing the regeneration rate, so that it is no longer visible as a characteristic of the plant.

After the two ninjas had undergone seven days of treatment and walked out of the treatment room on their own legs, all the ninjas lining up after them were jonin.

A month ago, the Third Hokage even came to ask in person, "Can you regenerate your eyes?"

Uchiha You rejected it at the time and said bluntly: "The eyes are different from all other systems of the body. They are absolutely independent systems. There is no way to regenerate them from scratch after losing them. They can only be transplanted."

He even asked back: "Third Hokage, as far as I know, Konoha Village's eye transplant technology is very mature, there is no need to consider regeneration, who on earth made such a boring request?"

The Third Hokage sighed and said, "It was Maruboshi Kosuke. He lost his eye while on a mission with me. I have always felt guilty about it and wanted to transplant an eye for him."

"But this guy just refused to accept the eyes of others and was unwilling to occupy resources that other ninjas might use. I really had no choice but to think about whether I could convince him with the reason of regeneration."

After repeated questioning, the Third Hokage finally gave up and sighed with deep regret: "What a pity."

Uchiha You politely sent the Third Hokage away. He had to say that he felt very good about Sarutobi Hiruzen just now.

He took his past misfortune seriously and tried his best to help him regain his sight. Even if he failed, he had no intention of taking his anger out on Uchiha You.

Unfortunately, this is only perfection in personal character. It would be great if Sarutobi Hiruzen could perform so well as the leader of Konoha Village.

What a pity! After muttering a few words, Uchiha You continued to busy himself with his own things.
