Fugaku has gone mad; he's going to create a new Uchiha clan in Kirigakure.

Mei Terumi sat down next to Fugaku Uchiha.

The wooden planks under the eaves creaked softly, a sound that was particularly clear in the stillness after the rain.

She placed her hands neatly on her knees, her back ramrod straight, her eyes fixed on the rain-soaked moss in the yard, but she dared not look at the person beside her.

"sorry."

She suddenly spoke, her voice low and tinged with embarrassment.

"I should have knocked first. I came at the wrong time."

She knew that her little movements couldn't be hidden from the owner of the Mangekyou Sharingan. Just thinking about what she had seen through the crack in the door made her ears burn again.

Fugaku Uchiha turned his head to look at her.

The light from the stove fire shone through the paper door, casting a soft, warm glow on her profile. Suddenly, he reached out and wrapped his arm around her waist.

"No."

Fugaku Uchiha's voice rang out above her head.

"You've come at just the right time."

Feeling Fugaku Uchiha's broad and warm embrace, Mei Terumi's heart pounded wildly, so loudly that she suspected he could hear it.

She couldn't help but turn around.

Through the thin crack in the paper door, she saw that Uchiha Mikoto was still curled up on the tatami, wrapped in a blanket, fast asleep, her breathing even and long, completely unaware of what was happening under the eaves.

For some inexplicable reason, an indescribable feeling welled up in Terumi Mei's heart.

I'm very happy.

It's very exciting.

"What brings you here?"

Fugaku Uchiha's voice pulled her back to reality.

Mei Terumi blushed, then secretly glanced at Mikoto Uchiha, who was still fast asleep in the room.

"I just... came to see you."

"Also, Hozuki Mangetsu said that if you wake up, he wants to see you."

Hozuki Full Moon...

Fugaku Uchiha searched his memories for the name, some from his previous incarnation, some from his past life...

A genius ninja from Kirigakure, the current head of the Hozuki clan, a genius who became the clan head at the age of seventeen.

The original work describes him very little. All that is known is that he mastered all the secret techniques of the Hozuki clan at a young age and was able to use the seven ninja swords skillfully. More importantly, the original work mentions that he died of disease.

For powerful ninjas, it's almost impossible for them to get sick. If they do get sick, there's only one possibility: bloodline disease.

That is, the same disease as Kimimaro.

The so-called bloodline disease is not actually a disease, but simply a bloodline limit that is too strong for the body to withstand. The development of a bloodline limit requires a massive amount of nutrition and vitality. Nutrition is easy to obtain, as money can provide it, but vitality is not so. As he said before, the ninja world lacks materials to replenish vitality, and those materials cannot be directly consumed or absorbed.

His [Blade of the Underworld] can only absorb external energy and convert it into chakra; it cannot reverse this process, just like a Pixiu, which only takes in and never gives out.

As for his right eye, it can indeed generate almost infinite life force. Unfortunately, this life force can only be transferred through certain special means. Since he is not from Chengdu, he is unable to help Hozuki Mangetsu with his illness.

Or to be more precise, at least until he can summon the exclusive weapon of his right Mangekyou Sharingan, it is impossible. And to summon the exclusive weapon of his right Mangekyou Sharingan, according to the innate memories written in his eyes, he must at least reach the fourth stage of Susanoo, which is the ultimate form of the Mangekyou Sharingan.

Don't be fooled by the fact that they only differ by one form. As the saying goes, sometimes the difference between two Golden Cores is greater than the difference between a Golden Core and a Qi Refining cultivator.

In the original work, only Madara Uchiha and Sasuke Uchiha ever used this fourth form of Susanoo. Even Itachi Uchiha, that beast, only reached the third form.

In other words, Fugaku Uchiha had reason to believe that simply piling up chakra was no longer enough to reach the fourth form; he might need Indra's chakra as a "catalyst." It sounds like a ridiculous bloodline story, but on the other hand, chakra and the Divine Tree were weapons of war for the Otsutsuki clan, a cosmic civilization capable of traversing the void.

It's like a spaceship; to use its ultimate weapon, you need the highest authority, which is perfectly normal...

Therefore, Fugaku Uchiha believes that the solution to this matter will likely be to focus on Sasuke...

...

"Why would he want to see me?"

As his thoughts returned, Fugaku Uchiha held Mei Terumi's hand and gently stroked her smooth, fragrant hair, realizing that this woman had also taken a bath.

"He and I are the backbone of the Ninja Clan Alliance."

"Leaning on Fugaku Uchiha," Mei Terumi said.

"After you join us, we will become the third major power. In the future, we will need to have a formal exchange to deal with the faction led by the Fourth Mizukage, or rather, the mysterious person who controls him. Some things and some positions need to be made clear face to face."

Fugaku Uchiha nodded.

"Can."

He paused, then suddenly remembered something.

"By the way, there are two things you need to know about the eye I gave you."

"First, transplanting Sharingan into an outsider consumes a tremendous amount of chakra. Take Kakashi Hatake, the white-haired ninja who escaped from Konoha. He was the son of Sakumo Hatake, and had a very promising future, but because he transplanted the Sharingan, his chakra was constantly being depleted."

Why?

"Because outsiders cannot turn off the Sharingan, it will remain in an active state, continuously consuming chakra."

"Kakashi is called the 'Copy Ninja' not because he likes to use the Sharingan, but because he has to use it. Since he can't turn it off, he has to make the most of it. However, this has resulted in his total chakra never increasing, which puts him at a disadvantage in prolonged battles."

After hearing this, Mei Terumi blinked.

Then, a slightly proud expression appeared on her face.

"That's not a problem."

She raised her chin slightly.

"From childhood to adulthood, I have never worried about the amount of chakra. On the contrary, the more I use it, the more I have. I can never run out of it."

Fugaku Uchiha was taken aback. He looked at the woman in front of him with a "I have a lot of chakra and I'm proud" expression and suddenly remembered the plot of the original work. It seemed that it was really true.

In the original story, during the battle between the Five Kage and Madara Uchiha, Mei Terumi's performance was relatively average, so he thought that this woman's strength was just so-so. But after thinking about her battle process carefully...

Lava Release: Melting Monster Technique, it sprays it like it's free.

Boiling Release: Skillful Mist Technique has an absurdly large range.

Water Release: Water Dragon Bullet, seven or eight of them can be fired at will.

Combining this with the memories he had acquired after arriving in this world, Fugaku Uchiha realized that Mei Terumi's chakra reserves were probably terrifying to an extreme degree, possibly even far exceeding those of the Uzumaki clan, which was known for its massive chakra reserves.

She's only in her early twenties, and there are still about ten years left in the original storyline. Her strength hasn't reached its peak yet, but even so, her chakra reserves are definitely not lacking.

"...Alright, then the second thing is that there is no professional storage environment here, so we need to do the surgery to replace it as soon as possible. If it is left for too long, the Sharingan that has been separated from the body may be damaged."

"But...the surgery requires a recovery period, which might affect combat effectiveness. The situation is still unstable right now, what if..."

"It's okay."

Fugaku Uchiha said with a smile.

"I have a secret medicine here. It can heal injuries immediately after you take it. It tastes a bit pungent, but the effect is very good."

"Really?"

"Of course it's true. I'll go see Hozuki Mangetsu first, then you can stay with me. I'll perform the surgery on you, and tonight... you can sleep here with me."

"Huh?"

Mei Terumi's face, which had just calmed down, flushed red again.

"Why?"

"no way."

Fugaku Uchiha shrugged, looking like he was saying, "I'm helpless too."

"The kind of special medicine I'm talking about can only be obtained from me. You need to take it immediately after your surgery, otherwise the recovery effect will be reduced."

Mei Terumi stared at him for several seconds, her Kage-level ninja instincts screaming alarm bells. She felt this guy had ulterior motives, but his expression was so serious and sincere. And thinking about it carefully, what he said made sense. Secret medicines always have some strange restrictions on their use.

She muttered something under her breath, but nodded nonetheless.

---Divider line

Somewhere in the Land of Whirlpools.

The underground cave was damp and cold, with water droplets condensing on the rock walls. Each drop fell into a puddle on the ground with a monotonous "drip-drip" sound. White Zetsu emerged from the wall, his body seemingly melting and reforming, finally transforming into a pale humanoid figure. He grinned, revealing an exaggerated smile...

...

"Lord Madara, that's the conversation I overheard~"

His voice echoed in the cave, carrying an unsettling merriment.

In the center of the cave, Obito Uchiha sat on a protruding rock, still wearing his orange spiral mask.

"What a despicable guy."

Obito remained silent for a few seconds, then suddenly sighed angrily.

"He opens his eyes and does that kind of thing... I really suspect that his Mangekyou Sharingan is used to enhance his abilities in that area."

"Possibly."

Black Zetsu echoed, his voice low and hoarse.

Obito turned his head and looked at him as if he were an idiot.

"Can't you tell I'm joking?"

"Who's joking with you?"

Black Zetsu also looked at Uchiha Obito.

"Didn't you hear it?"

"What are you listening to?"

"It's just...it's just...oh, sorry, I forgot, you're a newbie, it's normal that you don't understand."

"Go to hell!"

Obito cursed angrily, grabbed a rock from the side and threw it.

Black Zetsu laughed and dodged to the side. The rock smashed against the rock wall, broke into several pieces, and rolled into a puddle.

In short, it is—

Black Zetsu's smile vanished, and his voice returned to its previous somber tone.

"I've roughly figured out the capabilities of his two eyes."

"explain."

"Left eye, Huangquanjin Restaurant."

Black Zetsu said slowly.

"His ability is to absorb external energy and convert it into his own chakra. That's why he was able to activate the third stage of Susanoo. The combined ninjutsu of a thousand Konoha ninjas became his 'soldier rations'."

Obito nodded; he had already guessed this.

"What about the right eye?"

"Right eye...the name is not yet known."

Black Zetsu said.

"But one thing is certain: it can generate a huge amount of vitality."

"First, the pressure faced by hundreds of people engaging in reverse psychic communication."

"Second, the impact of hundreds of shadow clones disappearing at the same time."

"Third, even after continuously using the Mangekyou Sharingan and even activating the third stage of Susanoo, there were no aftereffects of decreased vision."

"Fourth, White Zetsu observed that Uchiha Mikoto's appearance has been getting younger and younger lately, and her skin and complexion are incredibly good."

"Therefore, his right eye is mostly related to vitality, which can help him repair damaged bodies and even damage to his eyes."

Obito Uchiha frowned.

"Wouldn't that be... an eternal kaleidoscope?"

"It's just like that."

Black Zetsu shook his head.

"It's still not quite the same as a true eternal kaleidoscope, but it's really powerful in specific scenarios, such as war."

"Moreover, this vitality should be able to be transferred to others."

"How do I transfer it?"

"Based on White Zetsu's observations..."

Black Zetsu's voice carried a hint of mockery.

"The change in Uchiha Mikoto occurred after they frequently engaged in marital relations, so it was probably transferred through the fluids in her body."

"The...fluid inside the body..."

Obito paused for a moment, then suddenly realized.

"You don't mean... you'd eat his saliva, do you?"

He showed a look of disgust.

"How disgusting..."

"Hehehe..."

Black Zetsu smiled without saying a word, offering no further explanation.

"Let's put this matter aside for now. A mere three-tomoe Sharingan won't have much impact on the overall situation. The real problem is that Fugaku Uchiha's arrival will disrupt the internal balance of Kirigakure under your control."

Factions...

Obito Uchiha took a deep breath, his whole demeanor becoming somewhat cold, because the mere mention of Kirigakure reminded him of those past events.

Currently, under his control, the Hidden Mist Village has split into two factions.

One faction, led by the Fourth Mizukage Yagura Karatachi, was the "non-bloodline limit faction," which advocated suppressing bloodline limit families and implementing the Blood Mist policy. The other faction, represented by Mei Terumi and Mangetsu Hozuki, was the "bloodline limit faction," also known as the Shinobi Alliance, which attempted to resist the Mizukage's rule.

Initially, the non-bloodline faction held the advantage, given their numerical superiority. However, since the rise of Mei Terumi and Mangetsu Hozuki, the bloodline faction has become increasingly powerful, subtly overtaking the non-bloodline faction. Now, with Fugaku Uchiha leading the Uchiha clan to join, once he officially integrates into Kirigakure, the strength of the bloodline faction will surge, and the balance will be completely broken.

"It doesn't matter."

Obito suddenly spoke, his voice tinged with weariness.

"Anyway, I've had enough fun."

The Blood Mist policy of Kirigakure was originally a toy he created for revenge and to create chaos. Now that he's tired of it, he can just throw it away. After all, no one knows better than him how many talented Kirigakure members he has ruined over the years.

"However, the rise of the Uchiha clan will affect you, especially Uchiha Fugaku. His Sharingan is very special; he was born with a near-eternal Mangekyou Sharingan. Before the Ten-Tails is born, he will be one of your most troublesome opponents. Don't forget, Kirigakure still has two tailed beasts, the Three-Tails and the Six-Tails."

Obito fell silent again.

I know my own abilities.

Kamui possesses the ability to become intangible, making him invincible in defense, but his offensive methods are relatively limited. If the opponent's right eye truly has infinite life force, a fight between the two could easily turn into a stalemate where "you can't hit me, and I can't wear you down either."

"Since you can't do it yourself, then do as I say."

Black Zetsu didn't expect Obito to offer any advice. To put it bluntly, without the Kamui Sharingan, Obito Uchiha was a complete waste. In fact, Black Zetsu didn't think much of this guy at all.

"To reiterate, for us, the ninja world can be turbulent in the coming years, but it's best to avoid major chaos. In a state of chaos, all nations will pay more attention to the tailed beasts, which will make our capture efforts more difficult, and the same applies to Kirigakure."

"So, since the problem lies in the Ninja Alliance becoming too powerful, then let's just let the Ninja Alliance descend into chaos..."
