A Risky Move, The Wicked Utatane Koharu

"You're treating me like a complete fool!" Uchiha Dan laughed in anger. "Even if I sign the contract, would I dare use it? If I don't dare use it, what's the point of learning it?"

"And if I remember correctly, the Sage Mode of Shikkotsu Forest is said to be the hardest to master, isn't it?" Uchiha Dan continued.

"Since recorded history began, the only one to ever master Shikkotsu Forest's Sage Mode was your grandfather, Hashirama Senju. Even your great-uncle couldn't learn it. Do you think I have that kind of talent?"

"So don't bring that up again!" Uchiha Dan said. "I'm very interested in quietly studying the slugs to improve my medical skills, but that alone definitely isn't enough."

"You should know I've not only created the Revival Technique you saw last time, but also several others I couldn't demonstrate due to Chakra limitations. Your conditions are too poor."

"Several others?" Tsunade's breathing grew rapid.

And that technique was called Revival Technique? Implying it had the power to bring the dead back to life?

Before Tsunade could offer more conditions, the office door was pushed open. A nurse walked in and said, "Doctor Dan, there's a patient here to see you. They specifically requested you for treatment."

"Got it!"

With that, Uchiha Dan grabbed his medical kit and fled like the wind, leaving Tsunade behind with a face full of frustration.

Days passed one after another.

At night, Uchiha Dan guided Namikaze Minato in training while verifying his own theories about ninjutsu.

During the day, he worked as usual.

The only difference was that Tsunade was now in his office.

Over time, Uchiha Dan gradually stopped rejecting Tsunade.

On the surface, it didn't seem like he had accepted her—rather, it looked more like he had resigned himself to fate, which infuriated Tsunade to no end.

But during this time as colleagues, the two frequently discussed medical arts and Medical Ninjutsu. Every time they talked, they both became completely absorbed, unable to tear themselves away.

As the ceiling of Medical Ninja, without Uchiha Dan, Tsunade truly had no one to discuss things with.

No one could keep up with her pace or offer her constructive advice.

Because she was the best.

Now that she had someone to talk to, everything changed.

The occasional ideas Tsunade offered made Uchiha Dan's eyes light up.

And the insights and plans Uchiha Dan proposed left Tsunade utterly captivated.

Because of this, Tsunade sighed more than once—how could this man be so brilliant and yet so infuriating at the same time?

As the number of patients they treated grew, Tsunade's reputation slowly spread.

The claim that Konoha's medical world had two unparalleled geniuses gained more and more recognition.

When they encountered interesting cases, the two would also study and treat them together.

Three months passed like this, and Uchiha Dan received a notice ordering him to go to the Pharmaceutical Department to develop a new Antidote.

Uchiha Dan keenly sensed that his opportunity had arrived.

To speed up the process of gaining freedom, he decided to take a risky move.

Seven years. He was tired. He really didn't want to drag this out any longer. After all, how many seven years does a person have?

In a secret room of the Pharmaceutical Department, this had become Uchiha Dan's exclusive laboratory.

But the ever-wary Utatane Koharu had people specifically watching him.

Uchiha Dan was long used to this scene. Having no freedom anywhere was the norm of his life.

Other aspects didn't matter much, but the key issue was that he didn't even have a chance to test the Flying Thunder God Technique.

As one of the Five Great Shinobi Villages, Konoha's strength was not to be underestimated. To successfully escape Konoha, the Flying Thunder God Technique was essential for Uchiha Dan.

Learning the Flying Thunder God Technique was a hopeless endeavor for others.

But the Flying Thunder God Technique was invented by the wicked Tobirama Senju, and Uchiha Dan possessed all of Tobirama Senju's talents.

So he had never doubted that he could learn the Flying Thunder God Technique.

Over these seven years, Uchiha Dan had long figured out the principles of the Flying Thunder God Technique, but he didn't dare practice it.

He was afraid that before he could learn it, he would be mercilessly eliminated.

But the Flying Thunder God Technique wasn't the kind of jutsu you could use just by understanding the principles. It required extensive practice.

Without mastering the Flying Thunder God, Uchiha Dan felt that this vast shinobi world had no place for him to call his own.

Sigh!

Letting out a breath, Uchiha Dan began taking out various medicinal ingredients, starting the preliminary processing and extraction of each one.

About ten minutes later, that old hag Utatane Koharu showed up herself.

"Get out!" After ordering the Security Section personnel to leave, the entire lab was left with only Uchiha Dan and Utatane Koharu.

"Evil Uchiha brat!" Utatane Koharu looked at Uchiha Dan with a cold, condescending expression. "Before noon today, you must prepare the Antidote and write down the formula. Otherwise, you will die without a doubt."

Hearing Utatane Koharu's words, Uchiha Dan's anger flared up uncontrollably.

This kind of scene had played out many times.

And Utatane Koharu was such a coward that if any third party were present, she would never dare to spout nonsense about an evil Uchiha brat—unlike Tobirama Senju, who was at least straightforward.

Only when no one else was around would this old hag instantly run her mouth, making Uchiha Dan want to kill her more than once.

I can't take down Hatake Sakumo, who's watching me, but I can't take you down either?

Among Tobirama Senju's many disciples, Utatane Koharu was the only female disciple.

When she was young, her looks were decent enough, and with Tobirama still alive back then, Koharu appeared very well-behaved, making her the undisputed group favorite.

She was also a Medical Ninja, and her skills among Medical Ninja were outstanding, reaching the level of an Elite Jonin.

It was widely acknowledged in the ninja world that Medical Ninja generally had weak combat ability—Tsunade was an exception.

So for Koharu to reach Elite Jonin level as a Medical Ninja was already quite impressive.

But ever since Tobirama Senju died, for seven whole years, as this old hag aged and stopped training for long periods, her strength had declined significantly.

In those seven years, no one knew that Uchiha Dan had already awakened the Three-Tomoe Sharingan.

With his current strength, killing this old hag would be really quite easy.

One genjutsu, and she'd be done for instantly.

But killing Koharu would only be a momentary thrill.

Not only would it bring no real benefit, it would also cost Uchiha Dan his own life.

Trading one life for another wasn't something he couldn't do.

But trading lives with Utatane Koharu?

Just thinking about it was damn not worth it!

Still, Uchiha Dan knew the reason Koharu treated him so poorly had little to do with Tobirama Senju.

As fellow Medical Ninja, Uchiha Dan's talent left this old hag in the dust by over a dozen streets.

Especially over time, it made Koharu feel like she was a complete and utter waste.

Naturally narrow-minded and having been a spoiled prodigy since childhood, Koharu's jealousy toward Uchiha Dan had twisted her beyond recognition.

If it weren't for the fact that Uchiha Dan genuinely helped her make money, she would have wanted him dead long ago.

There was another reason she targeted him, and it involved Kagami Uchiha.

In truth, this old hag Koharu hadn't originally held strong prejudice against the Uchiha Clan.

So during joint missions and the First Ninja World War, Koharu found herself unable to resist Kagami Uchiha—a strong, warm Uchiha man who had saved her many times.

But Kagami always kept his distance from Koharu.

Later, without even informing Koharu beforehand, he fell in love, got married, and now his kid could practically run errands.

This drove Koharu nearly insane.

Hiruzen Sarutobi pursued me, and I turned him down.

Mitokado Homura pursued me, and I turned him down.

Shimura Danzō never pursued me, but he once showed some interest.

And you, Kagami Uchiha, dared to treat me like this?

So the old hag came to hate the entire Uchiha Clan, venting all her anger on the unrelated Uchiha Dan.

Even though Kagami had been dead for seven years, the hatred in Koharu's heart never faded.
