Naruto: Mikoto and Tsunade, don't let either of them go.

The reason why the Fourth Hokage was so strong was because of his space-time ninjutsu—the Flying Thunder God Technique—and his superhuman reaction speed. The combination of these two made him the renowned Fourth Hokage.

Don't assume that just because you learned the first stage of Lightning Release Armor in a month, it's easy to learn. You should know that Uchiha Kakuzan and Uchiha Sasuke trained tirelessly for that month. Moreover, because they were in an illusion, they could train without restraint, without fear of mistakes, physical damage, or even death. Meanwhile, Sasuke had a teacher, Uchiha Kakuzan, standing beside him with a metal rod, watching him intently, which kept him in a constant state of tension.

In addition, Sasuke's talent was not bad, which is why he completed the first stage of the Lightning Release Armor training in just one month.

In fact, for an ordinary ninja, even the first stage of Lightning Release Armor is enough to benefit him for life. After all, as long as he masters the first stage of Lightning Release Armor and works hard to hone his physical body, becoming a Jonin is more than enough. Moreover, he is the kind of Jonin with superhuman speed and reaction speed. As long as you are not surrounded or you do not do anything reckless, your survival ability is very strong.

Three days before the one-month deadline, after Sasuke Uchiha successfully completed another training session with the Lightning Release Armor, Uchiha Kakuzan looked at Sasuke, who had just opened his eyes, and asked, "How does it feel? Have you fully mastered this secret technique?"

Uchiha Sasuke stood up, his body still crackling with residual electricity, and said with confidence in his eyes, "Yes, Master, I have completely mastered this secret technique, and I have not made a mistake for ten consecutive times."

Uchiha Kakuzan witnessed all of this and was greatly impressed by Sasuke's resilience. He hadn't expected Sasuke to have such a strong will. He had also experienced the pain of training in the Lightning Release Armor, and he hadn't expected Sasuke to adapt so quickly. This was far beyond his expectations.

Uchiha Kakuzan originally thought that Uchiha Sasuke would need at least a month to use the eye technique 'Fleeting Time' again before he could master the Lightning Release Armor. Unexpectedly, he succeeded in just one month.

The confidence in his eyes wasn't confidence in himself, but rather confidence built from the hardships, torment, and perseverance he had endured over the past month.

Uchiha Kakuyama nodded and said, "Then get ready. Master is about to end this training and dispel the illusion."

Sasuke, who was standing there, was somewhat taken aback when he heard Uchiha Kakuyama's words. In the nearly one month of training, he had gradually gotten used to this place and to training. He was a little surprised to suddenly hear his master say that it was over.

Uchiha Sasuke stammered, "Master, wasn't it still several days until the month was up? How come it's ending early?"

Uchiha Kakuyama smiled and shook his head, saying, "I didn't expect you to be able to cultivate so quickly, Sasuke. Your hard work is even more outstanding than your talent. Your performance this time surprised me. Now that you have mastered this secret technique, there is no point in staying here any longer. Besides, going back a few days earlier will prevent you from becoming too mentally exhausted."

Upon hearing Uchiha Kakuzan's praise, Uchiha Sasuke narrowed his eyes with delight and chuckled, completely abandoning his former aloof and adorable demeanor.

When Uchiha Kakuyama saw Sasuke's expression, he smiled. In the past month of spending time together, they had become familiar with each other, and Sasuke had long since relaxed around him.

Then, Uchiha Kakuzan glanced around at the scene, casually forming a hand seal: 'Illusion--Dispel'.

······

When Uchiha Kazuyama and Uchiha Sasuke came to their senses, they found themselves in Mikoto's courtyard again. The autumn sun shone warmly on them, and a gentle breeze blew past their ears. For a moment, Uchiha Kazuyama and Sasuke were immersed in this environment.

After a short while, Uchiha Kakuzan gradually came to his senses. He met the gaze of Uchiha Sasuke, who had also come to his senses, and said softly to Sasuke, "Sasuke, try again. Don't worry, I'm watching you."

Uchiha Sasuke nodded vigorously upon hearing his master's words. He knew that it was time to test the results of his training. After all, even if you were proficient in the illusion, it didn't mean you had mastered it. In the end, you had to test your training results in reality. Only by succeeding in reality could you say that you had finally mastered this secret technique.

Uchiha Sasuke didn't even bother to check if the ground was clean before sitting down cross-legged. He took a deep breath to calm his nerves, then closed his eyes and slowly tried to find the feeling of training in the illusion space.

Meanwhile, Uchiha Mikoto and the others who were watching from the sidelines were somewhat confused. They saw Uchiha Kazuyama and Sasuke say something, Sasuke nodded, then Uchiha Kazuyama activated his Mangekyou Sharingan, and then Uchiha Kazuyama deactivated his Mangekyou Sharingan. Uchiha Sasuke then inexplicably sat down on the ground.

Just as they were wondering what was going on, they suddenly noticed some sky-blue lightning crackling around Uchiha Sasuke, who was sitting down. Uchiha Mikoto, who was somewhat knowledgeable about such things, covered her mouth in alarm when she saw it.

Mikoto Uchiha might not know much else, but she did know that when it came to manipulating lightning-style chakra, whether it was form transformation or nature transformation, a single mishanded move could result in injury. And of course, she knew this about her own son.

Although Sasuke may have inherited his lightning chakra, he has never learned any lightning-style ninjutsu, let alone a self-inflicted technique. This oversight could lead to his injury.

Although Mikoto Uchiha wanted to step forward to stop him, she knew that this was a crucial moment for Sasuke to use his ninjutsu, and that rushing over to stop him would only cause him to be injured more severely. So she could only cover her mouth and try not to make a sound so as not to disturb her son.

P.S.: Thank you to Qingshankeran, Xiwangmu, You, and Yanyuqingzhou for your support and love. Thank you all for your attention, encouragement, and gifts.

Chapter 135 Secret Techniques and Mikoto's Exuberant Dance

Chapter 135 Secret Techniques and Mikoto's Exuberant Dance

Mikoto Uchiha now only hoped that Uchiha Kazuyama, who was beside Sasuke, could save him in time if he was in danger. If Mikoto remembered correctly, in her recent memory, Kazuyama was also skilled in Lightning Release, although his use of Lightning Release was a bit off. Thinking of this, Mikoto's face flushed slightly.

Seeing Uchiha Mikoto nervously covering her mouth, the two maids beside her, Uchiha Izumi and Uchiha Ye, although they did not have Uchiha Mikoto's experience, could also see the nervousness in Uchiha Mikoto, the clan leader's wife. They involuntarily held their breath and looked at Uchiha Sasuke sitting on the ground.

Meanwhile, Uchiha Okayama, who was standing next to Uchiha Sasuke, was ready to make a move at any moment. Although Sasuke had trained very well in the genjutsu, they were now in reality. If he wasn't careful, Uchiha Sasuke would have to stay in the hospital for at least a few days.

Sasuke Uchiha sat on the ground, closed his eyes tightly, and began his first training session in the real world to master the Lightning Release Armor.

In contrast to the tense atmosphere surrounding him, Uchiha Sasuke was quite calm. After all, he didn't know how many times he had trained and how much suffering he had endured in the genjutsu. It's important to understand that in the genjutsu, aside from the lack of physical harm, the mental pain was no less intense. Moreover, being a spiritual being, his senses were more acute and refined when experiencing pain, making the suffering much clearer.

Therefore, after enduring so much hardship and working so hard for so long, Uchiha Sasuke was very confident that his efforts would not be in vain and that he would definitely succeed.

Sasuke Uchiha calmed his mind and focused on controlling and manipulating his chakra, guiding it to slowly work on his body.

······

Under the watchful eyes of the onlookers, first, wisps of electricity began to travel and surge from Uchiha Sasuke's body. Gradually, more and more electricity appeared, and the sound of thunder grew louder and louder, with crackling sounds filling the air.

In the end, the lightning on Uchiha Sasuke's body had covered his entire body, and the originally ear-piercing thunder suddenly turned into a low buzzing sound.

Uchiha Kakuyama, who had been watching over Sasuke the whole time, breathed a sigh of relief upon seeing this. He knew that Sasuke's first training session in the real world had been successful. Next, Sasuke would need to activate his Lightning Release Armor to stimulate and promote the growth of his physical body, making it even stronger.

Then, Uchiha Kakuyama saw Mikoto watching Sasuke intently from the side, so he strolled over to her.

When Uchiha Mikoto saw Uchiha Kyuuyama approaching, she grasped at a last straw and anxiously asked, "Kyuuyama-kun, how is Sasuke? Is he alright?"

Seeing this, Uchiha Kakuzan quickly comforted him, "Don't worry, Mikoto-nee, I've been watching. I taught Sasuke a secret technique, and he has already mastered it."

Upon hearing Uchiha Kakuzan's words of comfort, Uchiha Mikoto became somewhat flustered and stammered, "Lightning Release Secret Technique? It's already successful? This... that..." She even started gesturing with her hands.

Mikoto Uchiha is no novice. Although her strength is not that great, as the wife of the Uchiha clan's head, her knowledge and experience, gained through daily exposure, far surpass those of ordinary Jonin.

What are secret techniques? Secret techniques are called secret techniques to distinguish them from ninjutsu. All secret techniques have one thing in common: they are extremely difficult to master. Some people without talent may not be able to master them even if they practice for a lifetime.

Of course, the reason why so many people still try to master secret techniques is because the more difficult a secret technique is to master, the greater its power. And those top-tier secret techniques can truly be said to provide for one's entire life if mastered, providing a secure livelihood for the rest of one's life.

Mikoto Uchiha knew some secret techniques. Although they were very powerful, the difficulty of mastering them was outrageous. Moreover, eight out of ten of these techniques were life-threatening to be practiced.

This is why Mikoto Uchiha was at a loss after hearing what Okayama Uchiha said.

It's important to know that Uchiha Sasuke has been under her watchful eye since birth. If there's anyone in the world who understands Uchiha Sasuke the most, it's none other than her.

And now, right under her nose, her son has instantly learned a secret technique and is practicing it. This gave Uchiha Mikoto an absurd idea: could her son, Uchiha Sasuke, actually be a super genius, capable of crushing Qiu Shanjun, Shisui, and Itachi? (In her mind, Qiu Shanjun was the genius who crushed everyone else.)

Seeing that Mikoto seemed to have her worldview shaken, Uchiha Kakuyama smiled and comforted her, "Mikoto, don't worry, Sasuke is fine. There are some things I'll explain to you later."

After Uchiha Kakuyama finished speaking, he tapped his eyes twice under Mikoto's questioning gaze.

After seeing the hint given to her by Qiushan-jun, Mikoto Uchiha, who knew some of Qiushan-jun's background, suddenly realized what was going on. She breathed a sigh of relief when she learned that Qiushan-jun had helped Sasuke in a way she didn't understand.

The two maids watching from the sidelines were also confused about what had happened, but they didn't dare ask Uchiha Kakuzan. After all, Uchiha Kakuzan was the vice-clan head; despite his usual gentle demeanor, they wouldn't be so ungrateful as to do anything inappropriate.

Moreover, this concerns secret techniques. Although they don't know what secret techniques are, anything with the word "secret" in it is, in their minds, something that needs to be kept confidential. They won't inquire, they won't spread it, they won't know...

The two maids exchanged a glance, secretly stuck out their tongues, and then waited there with Uchiha Mikoto.

Meanwhile, Uchiha Izumi quietly returned to the house and brought a stool for the clan head's wife. News of the clan head's wife's pregnancy had already spread throughout the clan; everyone knew that, in order to set a good example for the clan and for the Uchiha clan to prosper and flourish, the clan head's wife had taken the lead by becoming pregnant with her third child.

The two maids, Uchiha Izumi and Uchiha Yoh, were temporarily assigned to help and take care of the clan leader's wife because she was unwell.

Chapter 136 Umino Iruka

Chapter 136 Umino Iruka

For a moment, the courtyard fell silent as everyone watched Sasuke, who was training in Lightning Release Armor, with a variety of thoughts on their minds.

Uchiha Kakuzan knew that Mikoto would definitely not go back to rest at this time, so he didn't try to persuade her anymore. Instead, he quietly stayed there with her, waiting for Uchiha Sasuke to finish his training.

About half an hour later, Uchiha Sasuke, who had been silent all along, finally changed. The lightning armor that had been covering him slowly thinned and decreased at a visible rate, and the low buzzing sound also gradually disappeared as the lightning decreased.

Finally, the lightning on Sasuke's body completely dissipated, and everyone who had been on tenterhooks breathed a sigh of relief.

A moment later, Sasuke Uchiha opened his eyes. His eyes were very bright and filled with joy. Slowly, Sasuke Uchiha stood up from the ground. However, he was a little weak and staggered when he stood up.

When Sasuke finished his training, Mikoto Uchiha ran to his side. When Sasuke staggered a little, she quickly helped him up, her eyes full of heartache, but she didn't say anything to blame him.

Uchiha Kakuzan, who was standing nearby, explained to Mikoto, "This is Sasuke's first time training. He overdid it and is now a little exhausted. It's alright, he just needs to rest. It won't affect him in the future."

Supported by Mikoto Uchiha, Sasuke Uchiha bowed to Okayama Uchiha and said, "Thank you, Master. I will do my best and not let you down."

Although Sasuke Uchiha was young, he could tell right from wrong. Uchiha Kakuzan had gone to great lengths to help him successfully train in the secret technique 'Lightning Release Armor', and even stayed with him in the illusion for a month. From childhood to adulthood, apart from his master Uchiha Kakuzan, no one had ever put in so much effort for him.

Uchiha Kakuzan chuckled and ruffled Sasuke's hair, saying with a smile, "Don't talk nonsense. I'm your master, this is what I should do. You have to work hard, and when you grow up, you'll be able to help your master."

Upon hearing his master's words, Uchiha Sasuke was somewhat distraught. He nodded vigorously, opened his mouth, and said with a hint of tears in his voice, "Don't worry, Master."

Uchiha Kakuyama watched as Uchiha Sasuke was helped into the house, but he didn't follow. Instead, he said something to the maid Uchiha Izumi who was waiting for him, and then left Mikoto's house.

Uchiha Kakuzan originally intended to take advantage of the two-day cooldown period of his eye technique 'Kotoamatsukami' to properly train Sasuke so that he wouldn't embarrass him too much. Unexpectedly, Uchiha Sasuke was quite promising and learned the secret technique 'Lightning Release Armor' prepared for him within a day.

Uchiha Kakuzan knew that with this secret technique as a foundation for Sasuke, as long as he didn't give up halfway, his future would definitely surprise everyone, including his brother Uchiha Itachi and his father Uchiha Fugaku. After all, in their hearts, Sasuke's performance was only mediocre and far from their expectations, so they had essentially given up on him. Uchiha Kakuzan believed that under his tutelage, Sasuke would definitely live up to expectations, after all, this was his only chance to surpass his brother.

Next, we need to deal with Tsunade's situation. As one of the Legendary Sannin of Konoha, the princess of the Senju clan, and a disciple of the Third Hokage, how can she not return to the village to serve for so long? Even if she has developed hemophobia, it shouldn't stop her from opening a medical team and continuing to contribute to the development of the village.

Most importantly, you are the only one left in the Senju clan. Shouldn't you make efforts and contributions to continue the Senju bloodline? The Senju clan, which has a history of thousands of years, can't just end with you.

Therefore, as the de facto ruler of Konoha Village, Uchiha Kakuzan absolutely could not allow such a waste to happen.

After leaving Mikoto's house, Uchiha Kakuzan went straight to the Hokage Building. As the Third Hokage, he had endless documents to handle every day, so if you wanted to find the Hokage, coming to the Hokage Building was almost always the way to go.

Uchiha Kakuzan was a rather special figure in the Anbu. First of all, before joining the Anbu, Uchiha Kakuzan's combat power had already reached the peak of the Kage level. With such combat power, not only in the Anbu, but also in Konoha Village and the ninja world, he was an existence that could do whatever he wanted. Therefore, even after entering the Anbu, apart from the Third Hokage, no one could command him.

Secondly, the Third Hokage recently promoted him again. When he first joined the Anbu, he was promised the position of captain. After he trained with Kakashi for a while, the Third Hokage simply put him in his own squad, under his direct leadership (actually, it was Uchiha Kakuzan who asked the Third Hokage to put him in his own squad so that he would have more freedom of action and be less controlled).

Therefore, when Uchiha Okayama came to the Hokage Building to meet the Third Hokage, he was completely ignored by the ANBU guards and entered the Hokage's office without any obstruction.

In the Hokage's office, Uchiha Kakuyama saw a familiar face: a Chunin wearing a headband and a green vest, with a large scar on his nose, standing properly in front of the desk, listening to the Third Hokage's teachings. Even when he heard someone open the door, he didn't turn around curiously.

Iruka Umino, Naruto's mentor, was the first teacher in Naruto to genuinely care for him. He had a great influence on Naruto and even acted as Naruto's father at his wedding.

The Third Hokage glanced at Uchiha Kazuyama who had entered, then continued his conversation with Iruka. Their conversation seemed to be nearing its end, as they exchanged a few more words before concluding. Iruka then respectfully bowed to the Third Hokage and left. Before exiting, he glanced curiously at Uchiha Kazuyama, wondering who was so bold as to casually enter the Hokage's office.

When Uchiha Kazuyama saw Iruka looking over, he smiled and nodded in response. He had a good impression of Iruka; although Iruka wasn't very strong, his character was commendable.

Iruka was somewhat taken aback after receiving Uchiha Kakuzan's response, since he didn't recognize the handsome man in front of him. However, after a moment of surprise, Iruka quickly realized that since the other party had shown goodwill, he smiled and nodded at Uchiha Kakuzan.

Chapter 137 The Third Hokage Paves the Way for You

Chapter 137 The Third Hokage Paves the Way for You

After Iruka left, the Third Hokage took a drag of his cigarette and, before Uchiha Kakuzan could speak, explained, "This child is named Umino Iruka. Although he is not very strong, he has a gentle personality and is more suitable to be a teacher. So I transferred him from his original team to teach students at the school."

“Naruto Uzumaki has reached the age to enroll in school, so I asked Iruka to take care of him. After all, given Naruto’s status, he will inevitably face isolation and exclusion after enrolling.”

"Although Iruka knows Naruto's identity, he is a kind-hearted boy and would never harm a child. You can rest assured about that."

Uchiha Kakuzan naturally trusted Iruka. After hearing the Third Hokage's explanation, he nodded to indicate that he understood.

After the Third Hokage finished explaining, he asked with some curiosity, "What brings you here today?" After all, in his memory, ever since Uchiha Kagami brought Uzumaki Karin back from Kusagakure, he had been dating Uzuki Yugao all the time, wandering around the streets, and had almost explored all the famous shopping streets and food streets in Konoha.

Uchiha Kakuzan didn't treat the Third Hokage like an outsider. He slammed his hands on the table, leaned on it, and said, "Old man, it's time for you to retire!"

The Third Hokage, upon hearing Uchiha Kakuzan's words, paused, assuming Kakuzan aspired to become Hokage. After taking a drag of his cigarette, he said, "Kakuzan, you're too hasty. Although I could directly announce my abdication and let you succeed me as Hokage, the other clans in the village won't agree. If you want to be Hokage, you should first select some of the elite members of your Uchiha clan and place them in key departments of Konoha, then gradually promote them until you control those departments. Of course, I will do my best to help you with all of this."

"Next, your Uchiha clan needs to network more with the other clans in the village, build good relationships, and gain their support. Finally, you also need to spread the good reputation of your Uchiha clan. After all, your Uchiha clan's reputation in the village isn't very good, and you need to change the impression you have in the minds of the Konoha residents."

"If you rashly take over the position of Hokage now, the people in the village will not agree. This will cause the entire village to fall apart and become fragmented. Moreover, they may discover that I am being controlled by you. All of this will prevent you from getting what you want."

The Third Hokage rambled on for a while, but noticing the increasingly strange look in Uchiha Kakuzan's eyes, he stopped talking and asked, "Is there something wrong with what I said?"

Uchiha Kakuzan looked at the Third Hokage with a strange expression: "How did you come up with so many things in such a short time? Or were you already prepared to withdraw?"

The Third Hokage took another puff of his cigarette, his expression carefree, and said with a smile, "Ever since you took control of me, I've been prepared to step down. What I just said was something I had planned beforehand, with the aim of ensuring the safety of the village and preventing it from falling apart after you become Hokage, so that the residents of Konoha would suffer in the end."

Upon hearing the Third Hokage's words, Uchiha Kakuzan couldn't help but look at the old man with new respect. It seemed that there was a reason why the Second Hokage had entrusted him with the position of Hokage. Although he was a bit confused now, he had still made many contributions to Konoha.

Uchiha Kakuyama waved his hand and said, "Don't worry, I won't become Hokage. I want you to step down and let Tsunade come back to take over the Hokage position. After all, with her status and achievements, she is the most suitable person to be Hokage." (I'm the kind of man who wants to be Hokage.)

The Third Hokage breathed a sigh of relief when he heard that it wasn't Uchiha Kakuzan who was going to become Hokage. But when he heard that Tsunade should become Hokage, he immediately smiled bitterly, took a deep drag on his cigarette, and said, "Do you think I don't want to? I've wanted to give the Hokage position to Tsunade for a long time, but Tsunade is very angry about my inaction over the years. Not only does she ignore my attempts to recall her, but she even chased away Jiraiya, who was trying to deliver a message to her."

Upon hearing the Third Hokage's complaints, Uchiha Kakuzan declared righteously, "This Tsunade is outrageous! She even ignored the recall notice from her teacher, the Third Hokage. No ninja in Konoha would stand by and watch. Now is the time when Konoha needs her. I will personally go and persuade her until she is convinced."

Hearing Uchiha Qiushan's righteous words, the Third Hokage looked at him suspiciously and asked, "Qiushan, what is your purpose in wanting Tsunade to come back? She has already left Konoha and poses no threat to you. Moreover, she is the granddaughter of the First Hokage, Hashirama Senju. Please, for the sake of the First Hokage, do not harm her."

The Third Hokage knew some of Uchiha Kakuzan's secrets. With his strength, Tsunade should be no match for him. Moreover, Tsunade suffered from hemophobia, which would put her at a greater disadvantage in battle. Knowing that he could not refuse Uchiha Kakuzan's orders, the Third Hokage had no choice but to plead for Tsunade, hoping that Uchiha Kakuzan would abandon his plans to harm her.

Seeing the Third Hokage's wary look, Uchiha Kakuyama knew he wasn't the kind of person who could stand up for justice, so he told part of the truth: "I'm confident I can get the Raikage lineage's method for training the third stage of the Lightning Release Armor, but I'm missing the second stage. I plan to train the third stage directly, and I need someone with extremely high medical skills to watch over me and help me at any time."

The Third Hokage knew that Uchiha Kakuzan had already completed the first stage of the Lightning Release Armor. He had previously approached him, asking him to try and obtain the training method for the second stage of the Lightning Release Armor. However, since it might expose their village's spies lurking in Kumogakure, Uchiha Kakuzan gave up. Unexpectedly, Uchiha Kakuzan actually obtained the training method for the third stage and was preparing to start training directly, with Tsunade by his side ready to help at any time.

Although the Third Hokage knew he couldn't persuade Uchiha Kazuyama, he still said, "Kuyama, you are still young, and your strength is already very high. There is no need for you to risk your life to train for that Lightning Release Armor."

Uchiha Kakuzan knew the Third Hokage meant well in advising him, but he still insisted, "Don't worry, I'm well-informed. Besides, even stronger enemies will appear in the future. If I slack off now, I'll regret it later."

Chapter 138 Tsunade's Recall Letter

Chapter 138 Tsunade's Recall Letter

Upon hearing Uchiha Kakuzan's words, the Third Hokage's hand, which had been steadily holding his pipe, suddenly trembled violently, and his gaze towards Uchiha Kakuzan instantly turned to horror.

How could the shrewd and experienced Third Hokage not understand what Uchiha Kakuzan meant? Besides, his disciple Jiraiya was always saying that he was entrusted by the Toad Sage to find the Chosen One, saying that there would be a great disaster in the ninja world in the future, and only the Chosen One could save the world.

The Third Hokage at the time didn't take these things seriously, but now, combined with what Uchiha Kakuyama said, it made the Third Hokage think more deeply.

Seeing the Third Hokage's expression, Uchiha Kakuzan realized he had let something slip, but it didn't matter anymore, since he already had the Third Hokage under his control.

The Third Hokage was already puzzled. This Uchiha Kakuzan seemed to have appeared out of nowhere. Although he had his past experiences, he had always acted in an ordinary way. Unexpectedly, he suddenly exploded, not only with a strength that was breathtaking, but also with this divine skill of controlling others.

You should know that the Third Hokage was known as the "Professor of the Ninja World." You can say that his strength wasn't great, but you can't say that his knowledge and experience were lacking.

This is also what puzzled the Third Hokage, Hiruzen Sarutobi. Before being affected, he had never heard of such a genjutsu that could permanently control others. After being controlled by Uchiha Kakuzan, although he could not do anything detrimental to Uchiha Kakuzan, he still had a great deal of autonomy and could still look up information.
