Naruto: My Sharingan is about to burst!

"come in."

Upon hearing Fugaku Uchiha's voice and receiving permission, Uchiha Kakuzan did not stand on ceremony and strolled into the tea room where the clan head usually entertained guests.

After Uchiha Okayama entered the room, he found that Uchiha Fugaku was already wearing a kimono and sitting upright, obviously waiting for his arrival.

Fugaku Uchiha took Uchiha Kakuyama's arrival quite seriously, after all, Kakuyama was a genius ninja of the Uchiha clan, on par with Uchiha Shisui. Although Kakuyama might not be his match yet, he was still a high-level combatant of the Uchiha clan.

Uchiha Kakuzan sat down and was about to speak when a beautiful woman in a kimono, with a slender figure and pretty face, walked in carrying a tea tray.

The beautiful woman didn't say anything. She served them hot tea and snacks, nodded to Uchiha Kakuzan, and then left.

Uchiha Okayama thanked her and waited for the clan head's wife, Uchiha Mikoto, to leave before speaking.

Uchiha Kakuzan planned to use the same old trick again; he didn't care if the scheme was old, as long as it worked.

"Chief, Qiu Shan has come here with important matters to report. There are too many people around during the day, so I had to come late at night to disturb you."

Fugaku Uchiha nodded in understanding.

"If there's anything important, just say it. As your clan leader, this is my responsibility."

Uchiha Kakuyama gets straight to the point.

"Qiu Shan came here this time because my Sharingan seems to have undergone some changes. As the clan leader knows, my parents passed away a few years ago. Since there is no one to consult with about this matter, I had no choice but to trouble the clan leader."

Fugaku Uchiha took a sip of tea and waved his hand.

"What are you saying, Qiu Shan? As the head of the Uchiha clan, and you are an elite ninja of our clan, it is my responsibility as the head of the clan to solve your problems."

"Qiu Shan, open your Sharingan, let me take a look at you."

Uchiha Kakuzan didn't stand on ceremony and immediately activated his Sharingan, revealing his Mangekyou Sharingan to Uchiha Fugaku.

Fugaku Uchiha certainly knew about the Mangekyou Sharingan, but he never expected that Uchiha Kazuyama could awaken the Mangekyou at such a young age. When the pattern of Uchiha Kazuyama's Mangekyou Sharingan was revealed, Fugaku Uchiha was completely unprepared and was shocked, standing there dumbfounded.

Fearing that things might get complicated if things dragged on, Uchiha Kakuzan took advantage of Uchiha Fugaku's surprise and lack of vigilance, and immediately activated his Mangekyou Sharingan, releasing the eye technique 'Kotoamatsukami'.

As the owner of the Mangekyou Sharingan, Fugaku Uchiha immediately sensed something was wrong when Uchiha Okayama activated the Mangekyou Sharingan and released his eye technique. He no longer cared about hiding his Mangekyou Sharingan and immediately activated his own Mangekyou Sharingan to resist the eye technique that was invading his brain.

However, Kotoamatsukami, known as the "strongest genjutsu," is not something that can be resisted so easily. Just as Fugaku Uchiha revealed his Mangekyou Sharingan, Kotoamatsukami had already invaded Fugaku Uchiha's brain with overwhelming force, altering his deepest thoughts and changing his will. From then on, his thoughts became Fugaku Uchiha's highest command.

After realizing that 'Kotoamatsukami' had succeeded, Uchiha Kagami slowly exhaled, finally feeling relieved.

Don't be fooled by how easily Kyuuyama controlled Fugaku Uchiha with Kotoamatsukami. That's because Fugaku Uchiha was caught off guard and didn't know that Kyuuyama possessed such an incredible eye technique as Kotoamatsukami.

Otherwise, as a fellow Mangekyou Sharingan user, Fugaku Uchiha not only had far more combat experience than Uchiha Kakuzan, but he was also still in his prime and had virtually no weaknesses. If Uchiha Kakuzan hadn't exploited an information gap, how could he have succeeded so easily?

Just as Fugaku Uchiha was being controlled by Kotoamatsukami, his wife Mikoto Uchiha, whether she sensed the commotion in the tea room or simply felt something was wrong, came in.

"Husband, what happened just now? I think I sensed a fluctuation of chakra. Are you alright?"

While Mikoto Uchiha was speaking, Fugaku Uchiha had already been transformed by Kotoamatsukami.

He slowly closed the kaleidoscope he had just turned on, picked up his teacup, took a sip of tea, and replied in the same tone and manner as usual:

"Mikoto, it's alright. I was just checking Okayama's Sharingan. You should go and rest. I still have something to discuss with Okayama."

The clan leader's wife, Uchiha Mikoto, never imagined that in such a short time, her husband's mind would be enslaved by Uchiha Okayama.

"Alright, I'll go rest now, Qiushan-kun. Excuse me." Uchiha Mikoto bowed slightly and turned to leave.

Whew, Uchiha Kakuyama let out a sigh of relief and wiped away non-existent cold sweat from his forehead.

That was incredibly dangerous. If he had made even the slightest mistake, Uchiha Kakuzan would have had no choice but to consider defecting.

However, risks and rewards are proportional. Now that he has control over Fugaku Uchiha and the Grand Elder supports him, it's as if the Uchiha clan is now in charge.

Now, it's time for you to reap the rewards.

Uchiha Kakuyama looked at Uchiha Fugaku, whose headmaster remained seated upright, calmly watching him.

"You know what happened, right?"

Fugaku Uchiha nodded.

“You have enslaved me, changed my mind, and now I am completely loyal to you. My life and death are entirely in your hands. Even if you ask me to do anything, including suicide, I will do it without hesitation, and I will not have the slightest complaint against you.”

"You were just using a Mangekyou Sharingan technique, weren't you? I didn't expect your technique to be so powerful; I was completely powerless to resist. However, I remembered that your Sharingan was more focused on copying, but I didn't expect your awakened Mangekyou Sharingan technique to be a top-tier genjutsu. I can't even use my backup plans."

At this point, Fugaku Uchiha shook his head regretfully, as if it were a great pity.

Upon hearing Fugaku Uchiha's words, Uchiha Kakuzan immediately broke out in a cold sweat, feeling extremely frightened. He never expected that Fugaku Uchiha would have a backup plan even at this critical moment.

Fugaku Uchiha seemed to have seen through Kiyama's thoughts, smiled, and comforted him:

"Rest assured, your eye technique makes me completely loyal to you and I will not do anything to harm you. I have already dispelled the contingency plan I left behind."

Chapter 11 Fugaku Uchiha's Kaleidoscope

Chapter Eleven: Fugaku Uchiha's Kaleidoscope

Although Uchiha Kakuzan used his eye technique to enslave Uchiha Fugaku, he still respected him.

"Chieftain, what other tricks do you have up your sleeve? Can you tell me?"

Upon hearing Uchiha Kakuzan's words, Uchiha Fugaku nodded and explained:

"Qiu Shan, do you know about the forbidden techniques unique to our Uchiha clan?"

Uchiha Kakuzan guessed, "Susanoo?"

Although Fugaku Uchiha was surprised that Uchiha Kakuzan knew about Susanoo, he still shook his head.

"Susanoo is a divine power unique to the Mangekyou Sharingan, but it's not a forbidden technique. The forbidden technique belonging to our Uchiha clan is 'Izanagi,' a technique that can change fate, altering everything unfavorable to me. Even if I die, as long as I've pre-set 'Izanagi' in my Sharingan, I can be resurrected when the time I set it is activated."

“I sensed something was wrong when you activated your eye technique. Just in case, before you controlled me, I set up Izanagi in my Sharingan to revive myself after a while and eliminate all factors that were detrimental to me.”

"I never expected that your eye technique would make me willingly obey your commands and prevent me from doing anything that would be detrimental to you. Since I had previously set up Izanagi to be detrimental to you, I had no choice but to cancel it."

Hearing Fugaku's explanation, Uchiha Kakuzan was filled with lingering fear. He realized he had narrowly escaped defeat and defection. The person who could become the head of the Uchiha clan was indeed no ordinary person. If he had been lazy and left a loophole when using Kotoamatsukami, Fugaku might have been able to turn the tables.

Izanagi is a forbidden technique of the Uchiha clan because no matter how powerful its effects are, the price of using it is the permanent blindness of one of the user's Sharingan eyes. Therefore, it was listed as a forbidden technique by the Uchiha clan.

"Clan leader, I just saw that your Mangekyou Sharingan has been awakened. So, what is its eye technique?" Uchiha Kakuzan was actually most concerned about the evolution of his own Sharingan. With the help of the system, he could copy other people's Mangekyou eye techniques and make them his own.

Uchiha Kakuzan understood that everything except his own strength was fake. Now that he had Uchiha Fugaku under control, it was only natural that he wanted to copy his Mangekyou Sharingan.

"My Mangekyou Sharingan's eye technique, the one in my left eye is 'Illusion - Momentary Time and Space,' which can bring the enemy's spirit into the illusionary space within my eye. In the world of my eye, the enemy has no ability to resist me. What seems like a moment in the outside world is actually a month in my illusionary space. However, it can only be used once a day." Uchiha Fugaku began to explain the abilities of his eye technique.

"It seems to be Itachi Uchiha's eye technique, an enhanced version of Tsukuyomi. However, it doesn't seem to be as capable of manipulating space and time within the Tsukuyomi dimension as Tsukuyomi, but the duration is longer than Tsukuyomi."

Uchiha Kakuzan stroked his chin as he listened to Uchiha Fugaku's story.

"The kaleidoscope eye technique in the right eye is 'Izanagi'."

Upon hearing Fugaku Uchiha's words, Okayama Uchiha almost jumped up. How could this be? It was simply unbelievable.

Fugaku Uchiha paid no attention to Okayama's reaction.

“I’ve already told you about the effects of ‘Izanagi,’ but as my Mangekyou Sharingan’s eye technique, the side effect is no longer blindness. Instead, it can only be used once a month. Moreover, compared to the ordinary ‘Izanagi,’ my eye technique’s activation time is much shorter; otherwise, it wouldn’t have been set up in an instant just now.”

Uchiha Kakuzan put his hand to his forehead. Indeed, one cannot underestimate the people of the world, let alone the Uchiha clan. This is simply cheating! No wonder the Uchiha clan was reduced to only a few people later on, and they still caused unrest in the ninja world.

To avoid any unforeseen complications, Uchiha Kakuyama decided to copy Uchiha Fugaku's Mangekyou Sharingan technique now, so that his own Sharingan would soon be ready to be upgraded.

"Clan leader, activate your Mangekyou Sharingan, and do not resist," Uchiha Kakuzan instructed.

“Okay.” Although Fugaku Uchiha didn’t know what Qiu Shan was planning to do, he still activated his Mangekyou Sharingan.

Upon seeing Fugaku Uchiha's Mangekyou Sharingan, Okayama Uchiha suppressed his joy at the prospect of gaining another eye technique and also activated his own three-tomoe Sharingan.

Because I am currently trying to copy Fugaku Uchiha's Mangekyou Sharingan, I cannot open Shisui Uchiha's Mangekyou Sharingan. Shisui's Sharingan technique is 'Kotoamatsukami'. If I want to copy Fugaku Uchiha's technique, I can only start with the three-tomoe Sharingan.

Uchiha Kakuzan compared his three-tomoe Sharingan to Uchiha Fugaku's Mangekyou Sharingan. The three-tomoe Sharingan in Kakuzan's eyes spun faster and faster, and soon, his three-tomoe Sharingan slowly transformed into the exact same pattern as Uchiha Fugaku's Mangekyou Sharingan. Fugaku's eye techniques 'Illusion - Momentary Time and Space' and 'Izanagi' were also copied by Uchiha Kakuzan.

At this point, it was equivalent to copying the potential, foundation, and characteristics of Fugaku Uchiha's Sharingan and merging them with the potential, foundation, and characteristics of Shisui Uchiha's Sharingan.

Because Uchiha Kakuzan's system doesn't just copy the Mangekyou Sharingan's eye techniques. If it only copied the eye techniques, Kakuzan's eyes would only deteriorate faster with use. Only by copying the potential, foundation, and characteristics of his Sharingan along with the eye techniques could Uchiha Kakuzan's Sharingan possibly upgrade and have a wider range of development.

The Sharingan of the Uchiha clan is divided into genjutsu eyes and copy eyes according to its characteristics. The representative of genjutsu eyes is Uchiha Shisui. After Uchiha Kakuzan copied Shisui's Mangekyou Sharingan, he also copied the characteristics of Shisui's eyes, which greatly enhanced Uchiha Kakuzan's genjutsu abilities.

The most prominent figures with the Copy Ninja are Uchiha Kazuyama and Uchiha Obito. Uchiha Kazuyama goes without saying, while Hatake Kakashi later earned the title of 'Copy Ninja Kakashi' by using the Sharingan given to him by Uchiha Obito.

Therefore, the more Sharingan Uchiha Kakuzan copies in the future, the more potential, characteristics, and foundation his Sharingan will gain. The system can then use these things as nourishment for Uchiha Kakuzan's Sharingan to upgrade and evolve. Without needing to transplant other people's Mangekyou Sharingan or Hashirama cells, it can help him continuously upgrade his Sharingan to Mangekyou Sharingan, Eternal Mangekyou Sharingan, Rinnegan, and Tomoe Rinnegan.

Chapter 12 Madam, you didn't want this either...

Chapter Twelve: Madam, you didn't want this either...

Just as Qiu Shan copied Fugaku Uchiha's Mangekyou Sharingan and slowly closed his Sharingan, feeling a sense of relief, a katana pierced through his back.

The katana pierced through his chest, and at the same time, it also pierced his still-beating heart.

Things happened so fast and suddenly that Uchiha Kakuzan hadn't even had time to react. He only felt a chill down his back and a sharp pain in his heart before watching helplessly as a blood-stained katana pierced through his chest.

There are many things like this: everything was going smoothly until you were about to achieve your goal, and then suddenly something unexpected happened.

Uchiha Kazuyama opened his mouth as if to say something, but his lips trembled a few times and he still couldn't say anything. His body, which had been sitting upright, slowly hunched over. Uchiha Kazuyama felt weak all over, and slowly, his body could no longer hold on and he fell to one side, revealing a slender figure standing behind him.

When Uchiha Mikoto collapsed on Uchiha Hill, she loosened her grip on her katana. Perhaps due to extreme tension, her fingers trembled slightly. Her face was pale, and the three tomoe in her eyes slowly rotated.

"Kyuu-kun, I didn't want to kill you, but if I don't kill you, I can't guarantee that Fugaku can recover. He is my husband, the father of my two children, and the head of the Uchiha clan. So, to ensure that nothing goes wrong, please die."

Mikoto Uchiha's words seemed to be addressed to Uchiha Okayama, or perhaps she was trying to convince herself. After saying these words, her trembling body gradually calmed down, and she turned and walked towards Fugaku Uchiha.

Uchiha Kakuzan lay helplessly on the ground. He knew where he had gone wrong when he heard Uchiha Mikoto's voice.

He underestimated others, especially Uchiha Mikoto. He thought that controlling Uchiha Fugaku would be enough, but he didn't expect that Uchiha Mikoto had already noticed something was wrong and struck him deadly when he was most relaxed, leaving him no chance to turn the tables.

Uchiha Kakuzan felt a chill run through his body, and his vision blurred. He knew that his time was running out.

Now, even the thousands of ninjutsu he's learned can't save him, and neither can his Mangekyou Sharingan. 'Kotoamatsukami'

"It's an illusion, it can only be used on others, it can't save myself, I can only rely on the system, and on the 'Izanagi' that I just copied."

Just as Uchiha Kakuzan activated his Mangekyou Sharingan, intending to use 'Izanagi', the system's notification completely shattered his hopes.

"Friendly reminder to the host: The eye technique 'Izanagi' is currently being learned and digested, and is expected to be usable in one hour."

"Damn system, I'll be dead in an hour, what's the point of using it?" Uchiha Kakuyama cursed in despair.

Just then, the system seemed to have also learned of Uchiha Kakuyama's perilous situation, and notification sounds kept ringing out.

"The system has detected a life-threatening situation for the host. The learning and assimilation of the eye technique 'Illusion - Fleeting Moment' has been paused, while the learning and assimilation of the eye technique 'Izanagi' has been accelerated. The learning is expected to be completed in half an hour."

"The system has detected that the host's life is under threat. It is operating at full capacity to accelerate the learning and assimilation of the eye technique 'Izanagi'. The learning is expected to be completed in ten minutes."

"The system has detected that the host is in imminent danger and is operating at overload. It is strengthening the learning and assimilation of the eye technique 'Izanagi'. The learning is expected to be completed in five minutes."
