Izuna, restore the glory of the Uchiha!

He made the right bet.

There were no survivors; this conclusion was based on details of the surgery during the day.

As early as when he performed open-heart surgery on Tobirama, he realized that Tobirama's forced endurance of the pain of having his heart ripped out was not simply a show of strength, nor was it a sign of being at someone's mercy.

He is cooperating.

He was observing.

From conversations with their own family physicians, it's easy to see that even the chief physicians of powerful clans in this era only had a superficial understanding of modern anatomy and surgery.

Without a solid theoretical foundation, who would dare to let the enemy operate on their still-beating heart?

Why was Tobirama Senju so convinced of the importance of surgery? How could he remain calm when his chest was opened?

Combining the information from the original work with today's reaction, the answer is obvious—Tobirama Senju had already begun conducting human experiments long ago, and his understanding of human anatomy far surpassed that of any other physician of his time.

Recovering from the shock of his secrets being exposed, Tobirama's previously ashen eyes suddenly sharpened, and he retorted sharply:

"Uchiha Izuna, stop pretending to be a saint. Haven't you done just as much as I have?"

As a pioneer in this field, Tobirama knew better than anyone else that Izuna's precise technique and unhurried knife skills could not be learned by training on pigs, dogs, cattle, or sheep.

If we're talking about sins, this smiling man before me is probably far worse than I am.

"Well..."

Izuna touched his nose, feeling it wouldn't be right to admit that he was standing on the shoulders of giants to see the world.

Before today, the only animals forced to die by his blade were mice and rabbits.

This ambiguous attitude led Tobirama to tacitly accept his guess.

The air froze once again.

As a genius of the ninja world, Tobirama Senju's frustration at this moment was not only due to his defeat and capture.

His new techniques were seen through, his secrets were exposed, and his proud skills appeared clumsy and incompetent in front of his opponents... all of this dealt a devastating blow to his self-esteem.

In other words, his spirit is almost worn down.

Izuna knew the timing well; the time had come to reveal the true intentions.

"While you're receiving treatment, my lab happens to be short of an assistant..."

"impossible!"

Tobirama almost instinctively growled in refusal.

"Don't rush. If you're willing to come, I wouldn't mind sharing..."

Izuna leaned forward slightly, his voice full of seduction.

"If I'm not mistaken, you don't even have a single set of standard human anatomy data yet, do you?"

Of course... no.

"Various complete organ samples..."

Then again.

"And here's the tutorial for my surgery today."

This is simply irresistible!

Having spent years immersed in the laboratory and working in various project teams, Izuna may not boast about anything else, but when it comes to the ability to paint a rosy picture for his subordinates, he is absolutely top-notch.

Tobirama's face turned from pale to white, then flushed red. In this intense internal struggle, his originally weak face regained some color.

Reason told him that this was aiding the enemy, a betrayal.

But then I thought, this defeat is already a foregone conclusion, and the Uchiha clan will definitely make exorbitant demands in the upcoming negotiations.

If I can endure the humiliation and gain access to the medical technology from this guy, it wouldn't be a bad compensation...

a long time.

"Then I...willingly..."

Izuna's smile blossomed completely.

Successfully won.

……

At this leisurely pace, it will take at least another week to get back to the Uchiha clan's territory.

Izuna comfortably occupied the "premium seat" that originally belonged to the wounded, lying on the oxcart covered with soft straw, swaying gently with the monotonous creaking of the wheels.

He rested his hands behind his head, gazing at the vast, boundless sky above, his thoughts drifting far away.

If the original story had continued, Madara and Hashirama would have fought another war that would have reshaped the ninja world shortly after this body died, ultimately leading to the establishment of Konoha.

As a modern soul who cherishes peace, Izuna naturally did not want to remain in the Warring States period, where human life was as worthless as grass, constantly worrying about the safety of his own head.

But he was also keenly aware that if he simply went with the flow and allowed the Uchiha clan to gradually become marginalized and isolated after the village was built, his life would probably be even more difficult than on the battlefield.

Therefore, he had to get involved. At the very least, he needed to secure an unshakeable core position for the Uchiha clan in the future ninja village alliance.

Tobirama Senju is a key piece in the game.

In the original timeline, Tobirama's political skills were indeed brilliant: he suppressed the Uchiha clan, diminished the influence of the Senju clan, and promoted commoner ninjas to power.

From a macro perspective, this seems to safeguard the collective interests of Konoha.

Unfortunately, this strategy ultimately led to the indiscriminate oppression of those with innate strength, while failing to truly support the weak at their root.

This outwardly strong but inwardly weak political environment was precisely the root cause of Konoha's later various disasters and internal strife.

Izuna didn't expect to change Tobirama with just a few words.

All he had to do was use Tobirama as a variable to achieve his own goals.

There is another equally important factor in the situation—Uchiha Madara.

Since arriving in this world and taking over this body, the most undeniable thing is Madara's attitude.

Faced with his younger brother's various abnormal, even bizarre, behaviors, the only reaction of that ninja world demon was tolerance.

Unconditional tolerance.

Izuna couldn't help but think of the term "brother complex" in the encyclopedia.

Madara is not Hashirama; he doesn't have that carefree, optimistic personality.

He was perceptive and proud, yet he showed tenderness only to Izuna.

Whatever Izuna wants to do, as long as he's happy, Madara will accept it all and even pave the way for him without asking why.

He was on the battlefield, performing surgery on Tobirama.

Beforehand, Ban did not stop it; afterwards, Ban did not question it.

Madara, like most parents, was quite proud that Izuna had suddenly acquired a skill he had never heard of before.

That was Izuna, after all, his dearest younger brother.

It's just that I've acquired a small new skill, so what's so strange about that?

Thinking of this, Izuna's original scheming to take advantage of the plot suddenly made him feel uneasy.

He turned over, looked at the white clouds floating in the sky, struggled with his thoughts for a long time, and finally let out a long sigh.

"never mind……"

Since he's gone to such lengths, let's treat him like an older brother for now, unless there are major disagreements.

This is certainly partly due to the sense of responsibility that comes with taking over the original owner's body and assuming the karma of this bloodline;

But more importantly—

Non-vegetation, ruthless Practice makes perfect.

If someone is completely open with you, even willing to confide in you and entrust their back to you completely, and you still try to stab them in the back or scheme against them, you will never be able to get past your conscience for such a despicable and immoral act.

At this point, Izuna opened his eyes.

Then there's another thing that really alarmed him.
