Chapter Three: The Power of Shirou Emiya

"Now..."
"Their surname is Uchiha."
"The Uchiha clan and the Senju clan have been at odds for generations."

Tobirama Senju, as if he had finally found a kindred spirit, began to vent his grievances regarding the Uchiha: "My older brother defeated the Uchiha clan and persuaded them to join Konoha together. Yet, among them, there still exist those as evil as their ancestors..."

Tobirama did not notice a particular issue.

As the advisor to the Hokage of Konoha, he had been listening intently to the stories told by Emiya Shiyuan, and his trust in the man was growing rapidly; these were stories he found deeply compelling.

However, Tobirama could not possibly suspect a man from over a thousand years ago. He only knew that from Emiya Shiyuan's words, he had uncovered powerful evidence to justify keeping the Uchiha clan under surveillance!

"Brother..."
Tobirama’s expression darkened as he mentioned a person he detested: "He was also wounded by a naturally evil Uchiha..."
"That man... his name is Uchiha Madara."

When Tobirama spoke that name, he made no effort to hide his loathing and disdain: "Back then, my brother invited him to join forces to end the chaotic era. Yet, that man betrayed my brother's trust. Leaving Konoha was one thing, but when he returned, he attempted to destroy the village, kill my brother, and plunge the ninja world back into the fires of the Warring States period..."

Fortunately.
Uchiha Madara was finally dead.
His brother would no longer be held back by that man.

Emiya Shiyuan sighed, seemingly feeling a sense of pity: "It sounds like this Uchiha Madara you speak of was just as belligerent as his ancestor..."
"Back then..."
"Ashura wanted everyone to understand one another."
"But Indra wanted to dominate the ninja world."
"Despite being born of the same blood, the two brothers began a conflict for their differing ideals, one that did not cease even until their deaths..."

"Hmph!"
"That is the evil inherited in their very blood!"
Tobirama’s face looked grim as he harshly criticized the Uchiha clan: "Much like the Sharingan, the evil bloodline limit the Uchiha have inherited for generations..."

"The power of the Sharingan..."
Emiya Shiyuan spoke of the history behind the eyes: "I discovered early on that the power of the Sharingan slowly drives Indra toward extremism..."
"Correct."
"I, too, have researched the power of the Sharingan."
"This bloodline limit is inevitably manipulated by emotions."

Tobirama was well-versed in the Sharingan, and like someone meeting a soulmate, he spoke with absolute sincerity: "Because the evolution of the Sharingan is influenced by chakra born from extreme emotions..."
"Which also means..."
"The more powerful an Uchiha is, the more easily they drift toward extremism."
"The more extreme an Uchiha is, the more easily they become powerful..."

It was an unsolvable dilemma.
If an Uchiha's emotions could not be guided in the right direction, and they refused to live in peace, they would eventually become extremely dangerous.

They must be monitored!
They must be strictly monitored!
They must be centralized and kept under strict surveillance!

Tobirama secretly decided to implement his plan. Konoha's manpower was insufficient to monitor every single Uchiha, so they had to be gathered together for surveillance.
These Uchiha were currently still allies.
He needed to establish a new department for them.
This department would be managed exclusively by the Uchiha clan, and by consolidating their residential area, the Anbu could then quietly dispatch agents to keep them under tight watch.

Konoha Hospital.
The security here was extremely tight.
Because the battle between the First Hokage, Hashirama Senju, and Uchiha Madara had been so immense, the aftermath of their clash had altered the landscape of the ninja world, creating a valley at the site of their fight.
This battle could not be hidden from other ninja villages.
Villages from other nations had sent spies to infiltrate Konoha to gather information on Hashirama Senju. Since the safety of the First Hokage was tied to the peace of the ninja world, Konoha had no choice but to strictly seal off all information regarding him.

"Sasuke."
Tobirama suddenly called out loudly.
"..."
The corner of Emiya Shiyuan's eye twitched.
No...
Something wasn't right, was it?
How did Sasuke suddenly pop up?

***

This era shouldn't have been only a few years after the founding of Konoha, right?
According to the memories of his past life, this time should have been just after the Battle of the Valley of the End between Hashirama Senju and Uchiha Madara. How could there be a Sasuke here?

"Lord Tobirama!"
A young ninja strode forward to meet them.
The young ninja looked at Emiya Shiyuan beside Tobirama, his eyes filled with confusion and his voice laced with caution.
"Lord Tobirama, this is..."
"This is Lord Emiya Shiyuan."

Tobirama trusted this young ninja immensely and spoke in a low voice: "Sasuke, everyone can rest easy now; there is no need to worry about the state of the village."
"I used a forbidden technique to revive Lord Emiya and requested him to treat my brother's injuries. You must have heard his name; there will be no more problems with my brother's condition."

"Is that the great medical ninja, Lord Emiya?"
A flash of awe crossed the young ninja's face. He looked at Emiya Shiyuan in disbelief: "I grew up hearing Lord Emiya's name. I never imagined that one day I would actually see him in the flesh..."

"This is the leader of Konoha's Jonin squad, Sasuke Sarutobi."
Tobirama introduced the young ninja to Emiya Shiyuan before giving an order: "Sasuke, keep Lord Emiya's presence strictly confidential from those in the village..."

Although Tobirama held great power in Konoha as the Hokage's advisor, he did not rule as a total autocrat.
During the time Hashirama Senju was injured, the other ninja clans in the village were uneasy and had a right to be informed about the situation.
If an accident were to occur...
Konoha would inevitably face hostility from other ninja villages.
At this point, Tobirama had to unite the clans within the village so that Konoha would not collapse due to his brother's condition shortly after its founding.

The Sarutobi clan was a large ninja clan in Konoha.
The Ino-Shika-Cho trio—the Nara, Akimichi, and Yamanaka clans—had been led by the Sarutobi clan since the Warring States period.
Sasuke Sarutobi had been instrumental in helping stabilize the other clans, preventing the villagers from falling into panic, and introducing Emiya Shiyuan was intended to give Sasuke Sarutobi some peace of mind.
Tobirama letting Sasuke Sarutobi be responsible for protecting his brother was also a way to show that he trusted these clans enough. At the very least, compared to the internally isolated Hyuga and Uchiha clans, the Sarutobi clan was indeed trustworthy.

"I will take Lord Emiya to the ward now."
Tobirama patted Sasuke Sarutobi on the shoulder, taking the lead to guide the way while praising him to Emiya Shiyuan: "Sasuke Sarutobi is a ninja of resilient character and the head of the Sarutobi clan. Even I fall short of him in many respects..."
"Speaking of which, his son, Hiruzen Sarutobi, is also a very talented student. At his age, he has already mastered their clan’s summoning technique..."

As Tobirama said this, he looked at Emiya Shiyuan with a somewhat obscure gaze, seemingly hoping that Emiya might tell some stories about the ancestors of the Sarutobi clan.
"..."
Emiya Shiyuan looked at Tobirama with some surprise.
Did he want him to say something about the past of the Sarutobi clan?
He didn't know the past of the Sarutobi clan; he only knew their future.

Meeting Tobirama's gaze, Emiya Shiyuan gently shook his head: "In my era, the name of the Sarutobi clan did not yet exist..."
"In that era when the Ninja Sect was first founded..."
"Only the Sage of Six Paths possessed his own surname in the Ninja Sect."

"Ninja Sect?"
"Sage of Six Paths?"
Tobirama’s steps faltered. He stared fixedly at Emiya Shiyuan and instinctively asked: "Could it be that Lord Emiya has actually met the legendary deity?"

"Deity?"
Emiya Shiyuan looked surprised and examined Tobirama with curiosity: "The Senju clan... do they not have records of the Sage of Six Paths?"
"..."
Tobirama shook his head, then nodded: "To our era, the Sage of Six Paths is a mythological creator god who wielded the Heavenly沼 Spear to pacify the disasters of the ninja world, spread chakra across the world, and founded the ancient Ninja Sect..."

"That's about right."
Emiya Shiyuan was noncommittal about the Sage of Six Paths and casually dropped a bombshell: "I thought the Senju clan would have records, because the Sage of Six Paths was the father of your clan's ancestor, Ashura, and the Uchiha clan's ancestor, Indra..."

"..."
Tobirama’s heart couldn't stop racing.
Such a secret...
He had never heard of it!
The ancestors of the Senju and Uzumaki clans were both the Sage of Six Paths!
One could imagine what it would mean if this news about their progenitor were to leak. It was a pity this information came too late.
Of course.
It would be even better if the other party wasn't the ancestor of the Uchiha clan.
The Uchiha clan was already unruly; if they knew their ancestor was the Sage of Six Paths, they would likely become even more arrogant in the village.

"The Sage of Six Paths was a good man."
Emiya Shiyuan ignored Tobirama’s worries and continued on his own: "When I first proposed the concept of medical ninja in this world, the Sage of Six Paths was the first person to donate his remains after death for medical research and human experimentation..."

Of course.
Emiya Shiyuan did not mention the other truth.
The Sage of Six Paths' remains were not donated voluntarily.
Because the ninja system had triggered a mission to recover the remains of the Sage of Six Paths, and he had only completed the task by utilizing an ally.
He had obtained the remains of the Sage of Six Paths, which allowed him to gain the strength to truly stand firm in this world since his arrival. It was a pity that he ultimately did not find the secret to immortality within the Sage's remains; otherwise, he wouldn't have needed to traverse the barrier of death to reach this day...

[Name: Emiya Shiyuan (Wei Yuan)]
[Gender: Male]
[Profession: Ninja]
[Chakra Affinities: Fire, Wind, Lightning, Earth, Water, Yin, Yang]
[Chakra Energy: (A) Chakra is the fusion of physical energy and spiritual energy within the human body. It can enhance physical strength and affect lifespan.

[Bloodline Limits]
[Wood Style (S): Reward from the mission to recover the remains of the God Tree. A special bloodline limit activated by using chakra as the source of life. The techniques performed can absorb the enemy's chakra to make the technique even more powerful (Current power limited by the reanimated body).]
[Natural Rinnegan (S): Reward from the mission to recover the remains of the Sage of Six Paths. Possesses the ability to bridge Yin and Yang and master life and death. More powerful than an ordinary Rinnegan, capable of using many unfathomable ocular techniques, as well as a Susanoo that rivals the gods and is far superior to an Eternal Mangekyō Sharingan!

[Eternal Mangekyō Sharingan (S): Reward from the mission to recover the remains of the Sage of Six Paths. Possesses powerful visual observation, innate mastery of powerful genjutsu, and the magical ocular technique Kamui. Capable of activating the ultimate ocular technique, the Complete Body Susanoo!]

[Combat Modes]
[Cursed Seal Mode: Cultivated on his own by utilizing the God Tree remains' ability to absorb natural energy. Can be used to generate cursed seals containing natural energy. When the host's chakra is exhausted, the seals provide a continuous stream of converted natural energy to replenish chakra, or allow the host to fight in Cursed Seal Mode.]
[Sage Mode: Cultivated on his own based on the Cursed Seal Mode. Sage Mode originates from the perfect balance of physical, spiritual, and natural energy to generate senjutsu chakra. In Sage Mode, a ninja's perception and combat capabilities are greatly enhanced.]
[Six Paths Mode: Reward from the mission to recover the remains of the Sage of Six Paths. A perfect combat mode mastering both Yin and Yang, capable of enhancing all internal powers and utilizing Truth-Seeking Balls in combat. Using this mode will immediately break the Reanimation Jutsu and return the host to the afterlife or the space between the afterlife and the living world.]

[Skills]
[Swordplay (S), Taijutsu (S), Medical Ninjutsu (S): All self-cultivated. Medical Ninjutsu utilizes internal chakra to treat patients; mastering the Yang power allows for the curing of any disease (Currently limited by the reanimated body, unable to use Yang power).]

[Summoning Technique (S): Self-cultivated; the blood contract is with the Slugs of Shikkotsu Forest (Currently unable to summon due to the reanimated body).]
[Kamui (S): Ocular technique derived from the Mangekyō Sharingan, capable of creating a unique dimension to evade any attack or remotely absorb objects (Currently restricted in power by the reanimated body and chakra limit).]
[Shin-Mu (S): Ultimate ocular technique derived from the Rinnegan, capable of generating a hidden defensive mirror around the body. The mirror absorbs information from all techniques encountered by the host, allowing the host to reflect all incoming attacks, provided the technique's cost does not exceed the host's chakra limit (Currently unusable due to the reanimated body).]

On the surface, Emiya Shiyuan's strength was not weak.
In reality, it was indeed quite formidable.
The ability to cast any technique without hand seals alone provided an incomparable advantage in battle, not to mention the ultimate bloodline limits like the Eternal Mangekyō Sharingan and the Rinnegan, and the Six Paths Mode that surpassed ordinary ninjas.
However...
The reanimated state still could not unleash his true power.
It was a pity.
He had been revived a bit too early.

Emiya Shiyuan looked at Tobirama walking in front of him.
This guy, Tobirama...
He was not an easy man to deceive.
He was accustomed to wanting to keep everything under his control.
Emiya Shiyuan had noticed this the moment he was revived.
Tobirama had tried to control him, only temporarily dismissing the idea because he perceived Emiya as a kind and gentle man.
What a shame.
If someone with an evil nature had revived him using the Reanimation Jutsu, he could have easily deceived them and used his Rinnegan, left behind in this world, to truly resurrect himself...
