I, Yu Uchiha, am devoted to cultivating immortality

The threat Uchiha Yu was talking about was of course Uchiha Madara.

He didn't want Uchiha Madara to find the executor of the Infinite Tsukuyomi Plan. The uncertainty of the Mangekyō Sharingan Ninja was too great, and he really didn't know what the consequences would be.

So Yuu Uchiha not only kept a close eye on Uchiha Obito, he also ordered Elder Ryunosuke Uchiha to keep an eye on several ninjas in the family.

Tracking and surveillance is a very difficult job, especially when the target is a ninja, it is even more difficult. It takes several times as many ninjas to keep a firm eye on him.

Fortunately, there are not many weirdos like Uchiha Obito in the Uchiha family.

Excluding the children who are too talented and too young, and the two guys who are too old, there are only two people who need to be monitored by Uchiha Yuu, and one of them is Uchiha Obito.

The other target is called Uchiha Yae. She is a female ninja with a very gentle personality and a very kind heart. She is currently serving in the ordinary ninja team, but she has not been transferred to the front line like Obito.

This is a true holy mother who can sacrifice herself to protect others at any time. For the benefit of the team, she is even willing to learn medical ninjutsu.

When Uchiha Yuu first investigated this information, he thought it was his time travel companion. Fortunately, he ruled out this possibility.

Of course, Uchiha Yu had no way to prove whether she was a time traveler. He only verified through secret codes that she was not his fellow countryman, nor was she Xiaobaga or Xiaobangzi.

By the way, she doesn’t know English either.

To be honest, the cultural differences are to such an extent that even if this girl is really an earth traveler, she has nothing to do with Uchiha Yuu.

After closely watching Uchiha Yae and Uchiha Obito, Uchiha Yu felt at ease.

But when he clashed with Setsuna Uchiha at the banquet, and after his first contact with the elder's younger son, Yuu Uchiha was surprised to find that although the younger son of the elder Setsuna was surprisingly stupid, he had very good qualifications and rich emotions.

At that time, Uchiha Yuu's heart skipped a beat, but Uchiha Fugaku's ensuing attack made him unable to continue paying attention.

He was confined for the next few days, but his contact with the outside world was not cut off. Recalling the situation at that time, the sense of crisis in his intuition became stronger and stronger, so he ordered Uchiha Yuichiro to mobilize manpower to investigate all the elder families. young ninja.

The result surprised Uchiha Yu.

These young ninjas who are direct descendants of the Uchiha family, like Itachi Uchiha, live in deep mansions and enjoy luxurious living conditions like stars in the moon.

But unlike Uchiha Itachi, they almost never go out on missions, have almost no contact with ordinary Uchiha people, and live a life that is almost isolated from the outside world.

So much so that Uchiha Yu, a guy who grew up at the bottom, subconsciously ignored the existence of these second-generation people.

The investigation results show that although these second-generation ninjas have good and bad personalities, they are all extremely naive and extremely emotional.

For example, Uchiha Shota, who was beaten up by Uchiha Yuu and lost half of his teeth, upgraded from two magatama sharingan to three magatama sharingan in a mixture of shame and anger after he woke up.

What's even more frightening is that he also has an older brother, Uchiha Hayato, who also advanced to the Three Magatama Sharingan in anger after seeing his younger brother's face swelled to the size of a volleyball.

It's terrible.

These guys actually perfectly meet the conditions for awakening the Mangekyō Sharingan identified by Uchiha Madara.

This means that even if Uchiha Yuu sends Uchiha Obito to the Pure Land at a critical moment, Uchiha Madara's unlimited Tsukuyomi plan will not directly die.

He also has a list of candidates, including a brother who can synthesize the Eternal Mangekyō Sharingan.

This is troublesome.

The children of the elders all live in a deep compound, with sufficient manpower to protect them and many servants surrounding them, so there is no way to monitor them.

Uchiha Yu couldn't even arrange surveillance, because his own people were on the front line, and the only people in the village who could be used were two elders.

If they were asked to monitor the children of other elders, they would not be able to do it, and it would be easy for them to become estranged from Uchiha Yu because of things hurting their own kind.

After thinking about it, Uchiha Yu finally decided to give up monitoring these second-generation ninjas and instead adopt a more cruel plan.

After Uchiha Obito, the first target, was dealt with, if Uchiha Yuu failed to find and kill Uchiha Madara, he would have no choice but to go back and eliminate all the second generation Quan who could not be monitored.

It's very cruel, but his ability is limited and he can only use this method.

Uchiha Yu and Uchiha Shinyin fell into silence because of the cruel topic just now, and the courtyard fell into complete silence until it was broken by a burst of cheerful laughter and cat meowing.

Uchiha Shisui is back from training.

Uchiha Nobuyin's sorrow immediately disappeared, and he said to Uchiha Yuu with a smile on his face: "Since you went to the front line until now, you haven't seen Shisui, right? You will be surprised."

"It's less than a year, how much change can there be?" Uchiha Yu turned his head to look at the door in surprise.

The first person who walked through the door was a small calico cat. This was Yaeko, the ninja cat who signed a contract with Shisui after being introduced by Masato Miwa. She was a very qualified ninja cat.

Then a vigorous figure rushed in, hugged the calico cat, and said with a smile: "I caught Yaeko."

Uchiha Yu was really startled. He looked up and down carefully, but he didn't dare to confirm who it was.

The boy holding the calico cat saw him and shouted in surprise: "Brother You, is your confinement over?"

When Uchiha Yu heard this, he asked in disbelief: "Uchiha... Shisui?"

"Hey, it's me!" Uchiha Shisui proudly pointed at himself with his thumb and boasted, "Have you grown up a lot?"

Uchiha Yu nodded, he has indeed grown up a lot.

Uchiha Shisui has already grown to 136 centimeters before he is five years old. In just the past nine months, his height has grown by a full 15 centimeters, which is not a lot.

Uchiha Yu quickly asked: "Are you feeling any discomfort this year? For example, joint pain, muscle cramps, etc.?"

Shisui asked in surprise: "Hey, Brother Yu, how did you know that I had muscle cramps?"

Uchiha Yu explained: "This is common sense, okay? Children grow taller quickly and are most prone to muscle cramps."

Uchiha Shisui stuck out his tongue and glanced at Uchiha Shinyin secretly. The old man's face turned slightly red. It turned out that he didn't know this common sense.

Uchiha Shisui noticed the awkward atmosphere and quickly shouted: "Grandpa Shinyin, I'm hungry."

"Okay, let's have dinner. Let's have dinner right away."

"Yu, would you like to eat too?"

"When I come, um... okay, let's eat together."

Seeing Uchiha Shisui's expectant eyes, Uchiha Yu naturally changed his mind. Anyway, his belly was big enough, and the breakfast he ate along the way was nothing.

After being influenced by Uchiha Yu, the breakfast at Shisui's family was no longer the neon style, tasteless rice, natto and tofu kelp soup, but became meat and vegetable buns, siomai, pot stickers, fried cakes and beef soup.

This full of Chinese flavor made Uchiha Yuya unable to help but move his index finger.

But the one who ate more than him was Uchiha Shisui. This child devoured two drawers of steamed buns, a basket of siomai, some pot stickers, and drank two large bowls of beef soup with the pancakes.

Uchiha Yu and Uchiha Shinyin looked at him, fully understanding what it meant to be "a half-grown man living in poverty."

Fortunately, the Uchiha Shisui family was extremely wealthy, and if it were an ordinary family, they would really go bankrupt.

Although Shisui ate less than a quarter of what Uchiha Yuu did, Uchiha Yuu was a special case, and as a child, Shisui ate too much.

So, the worried Uchiha Yu stopped Shisui after the meal and performed a physical examination on him to prevent his digestive system from being overwhelmed. It turned out that the child was... malnourished?

The confused Uchiha Yu checked again and confirmed the result.

Digestive system, in excellent condition.

The blood circulation system is in excellent condition.

Endocrine system, in excellent condition

Bones and bone marrow are in good growth and development status, but slightly deficient in calcium.

The muscles and internal organs are in poor development and severely lacking in nutrition.

Uchiha Yuu was dumbfounded. Looking at Uchiha Shisui, who had grown a lot taller but had bulging ribs, he thought hard about how to find the reason.

Uchiha Nobuyin also realized that something was wrong at this time, and asked with concern: "Is there something wrong with the child Shisui?"

Uchiha Yu nodded and said: "Shisui has severe malnutrition, which greatly affects the development of muscles and internal organs."

Old man Xinyin looked confused and asked in disbelief: "This child can eat ten times more than before. How can he be malnourished? Is he lacking something?"

Uchiha Yu pointed at Shisui's ribs and limbs and said, "It's just malnutrition. Look, old man, there is no fat on his body at all, his bones are obvious, and his muscles are even stretched."

"What's missing is calories and protein, oh, oil, meat, noodles, and rice."

Uchiha Shisui and Uchiha Shinyin looked at each other. These were the things Shisui ate the most. They all thought they were missing vegetables and fruits, things that Shisui didn't like to eat recently.

Uchiha Yuya knew that his statement seemed ridiculous, so he added: "Shisui does eat a lot, but I don't know why it is not enough. His body is too thin. If this continues, there will be big problems."

Uchiha Shisui's thinness was extremely obvious. Shisui looked at his ribs. Both he and Xinyin had to believe that there was something wrong with his body.

So Uchiha Shisui raised his head and asked: "Brother Yu, what should I do? Do you want to eat more?"

Uchiha Yu directly objected: "No, your appetite is large enough now, and your digestive system has reached its limit. If you add gastrointestinal problems, there will be problems first."

“We still have to find the specific cause before we can prescribe the right medicine or solve the problem.”

Uchiha Nobuyin nodded and said: "Yu is right, you have to understand the problem first before you can find a way to solve it. You can't mess around."

After thinking for a while, Uchiha Yu said: "Shisui, I want to conduct a deeper examination on you. If you feel uncomfortable, remember to tell me."

After saying that, Uchiha Yuu called on the natural energy and carefully penetrated into Uchiha Shisui's body. Through this power that he had the deepest control, he sensed the natural energy and chakra that must exist in Shisui's body.

Get the details of Shisui's body changes through the most delicate feedback of natural energy.

The whole process was very time-consuming. It took Yu Uchiha a full two hours to complete all the inspections, but the results were surprising.

He patted Uchiha Shisui on the shoulder and said, "Congratulations, Shisui. Your bloodline has awakened."

Uchiha Shisui asked in surprise: "Is it the Sharingan?"

Uchiha Yu corrected: "No, you are changing towards the source of the Uchiha family bloodline, which means you are returning to your ancestors."

Seeing the hopeful yet disappointed look in Uchiha Shisui's eyes, he could only say: "Yes, your Sharingan will be awakened soon."

Uchiha Shisui happily danced the same old routine. He cheered and pulled Yaeko up to dance in the yard.

Uchiha Shinyin came over and said, "Boy Yuu, what will happen if Shisui's blood returns to his ancestors?"

Uchiha Yu replied: "The Sharingan will be awakened smoothly, upgraded without any obstacles along the way, and the Mangekyo Sharingan will be opened directly."

Old man Xinyin asked in surprise: "Awakening Kaleidoscope smoothly?"

Uchiha Yu explained: "Let me use an analogy. After Shisui's bloodline returned to its ancestors, it became a tall giant tree. The bloodline of ordinary Uchiha ninjas is just a short shrub, and the Sharingan is a huge fruit."

“It is a test of life and death for a short shrub to bear big fruits, but it is a matter of course for a big tree to bear big fruits.”

Uchiha Nobuyin nodded repeatedly, but he still asked worriedly: "Then why is his body malnourished?"

Uchihaou replied: "Returning bloodline requires too much consumption. Although Shisui's appetite is quite exaggerated, it is still not enough to make up for the consumption gap."

Seeing that old man Xinyin was anxious, he quickly said: "Don't worry, I can solve this problem."

"Do you remember the dried fish I gave you last year?"

"I remember, I was impressed."

"I will allocate a portion of dried small fish to Shisui. As long as one is eaten in four or five days, it will be enough to make up for the energy gap."

"Even his appetite will return to normal."

"Great, I feel relieved now."

In the afternoon, Uchiha Yu was led by Shisui to recognize the door of the study club. He met with several captains who were specifically responsible for management, and then spoke a few words with a few younger old members.

Finally, after saying "It's business as usual for the time being", he left with Uchiha Shisui.

No new official took office because he judged that it was not suitable now.

Although it was only a brief contact, Uchiha Yuya only chatted a few words with the 12 captains. He could also see that none of these guys were simple.

Those guys with provocative eyes and full of confidence must have the support of an elder or clan leader behind them. Those guys with wandering eyes and sweet mouths are definitely rare bastards in the Uchiha family.

Not only were every captain in trouble, but Yuu Uchiha also discovered that they had secretly formed an alliance against him.

If you can't find a suitable starting point and enter someone else's predetermined battlefield without hesitation, the result will definitely not be good.

So after he got the financial rights promised by the clan leader, he left, leaving these people there and letting them play with him.

Uchiha Yuu was convinced that it was impossible for these troublesome guys to have a harmonious relationship. As long as he did not get involved, they would definitely make trouble on their own after losing their biggest threat.

When things got really bad, and when they found out that the study club didn't have much money left, it was the right time for Uchiha Yu to intervene forcefully.

The most important thing at the moment is Shisui's problem. It is not difficult for Uchiha Yu to supplement nutrition, but it is important to figure out why Uchiha Shisui's bloodline has returned to his ancestors.

This is very important, very important to Uchiha Yu himself.

Returning to his home, Uchiha Yu solemnly taught Uchiha Shisui the Hundred Refining Exercises, the Circulation Refining Method, and the Meditation Soul Refining Method.

Uchiha Shisui is a true genius. After watching Uchiha Yu demonstrate the Hundred Refining Body Tempering Technique once, he immediately learned it and performed every move perfectly.

After only practicing twice, Shisui mastered all the essentials and achieved the maximum training effect.

At this time, Uchiha Shisui's sweat had soaked through his clothes, flowed down his trousers to the ground, and formed a small puddle.

Uchiha Shisui said excitedly: "Brother Yu, this body-building method is so powerful. It made me feel tired and sore in my muscles in such a short period of time. The exercise effect is really great."

Uchiha Yuu was delighted to find that Shisui had unconsciously improved three movements in just two exercises, and the effect was obviously better than what he had thought.

He secretly wrote down these three points, then asked Shisui to sit down and practice the circulation refining method while his body was tired.

Generally speaking, it is extremely difficult to refine chakra when the body is tired, but it is the best time to establish meridian circulation for the first time.

As long as the circulation is established, the difficulty of chakra extraction can be greatly reduced, and the extracted chakra can stay in the body longer, which is of great benefit to the body.

This time Shisui just followed Uchiha Yu's teachings and successfully established a chakra cycle without making any improvements.

Once the chakra cycle is established, you can start practicing the meditation and soul-burning method.

This time, Uchiha Yu took it upon himself to guide Shisui into the state step by step, allowing Shisui to experience perfect tranquility and soothing his nervous mind.

In the process of practicing the soul-forging method, Uchiha Shisui's mind relaxed, and then fell asleep in a deep sleepiness.

Uchiha Yu picked up Shisui and took him to his guest room, letting him sleep well.

Miwa Masashi asked curiously: "Why did Shisui fall asleep during training, nya?"

Uchiha Yu said with emotion: "He is too tired."

"Tired? He's still a child, meow."

"This kid Uchiha Shisui has too much sense of responsibility. He knows that there is something wrong with his body, but he is afraid that old man Shinyin will be too worried, so he endures it silently."

"It wasn't until I gave him enough confidence that I felt relieved."

"After entering a meditative state, the accumulated fatigue bursts out, and it's not like falling asleep."
