Chapter 104: Letting the Brother-in-law be the Guinea Pig

At dusk.

It was only during the shift change of the police force that they suddenly realized a squad was missing and couldn't be contacted at all.

Presumed to be in danger.

"What?!"

Upon receiving this news, Hiashi Hyuga was shocked and angry. He immediately ordered all members of the four squads of the police force to launch a large-scale search in and around the Leaf Village.

An hour later.

In a small grove in the Leaf Village park, the police force found the bodies of the squad members.

There were signs of a fight at the scene.

Without exception, all the deceased had external injuries. The poison had entered their bodies through the wounds, destroying their internal organs and leaving their bodies beyond recognition.

After an overnight investigation.

Early the next morning, the police force launched a vigorous search throughout the village, vowing to catch the criminals.

Hiashi Hyuga personally went to the Hokage building to report the situation to the Third Hokage.

Then.

The Third Hokage summoned Kakashi.

There were two photos on the table, taken by surveillance cameras of the criminals.

However.

Both of them were wearing straw hats and high-collared coats, and their faces couldn't be seen clearly. One could only vaguely see that they were a long-haired man and a hunchbacked person.

"Take two squads from the Anbu and help the police force catch the criminals as soon as possible."

The Third Hokage instructed Kakashi.

"Yes, Lord Hokage." Kakashi responded, turning to leave.

He hadn't taken two steps.

"Kakashi."

The Third Hokage suddenly called his name again, seemingly casually asking, "I heard from Hiashi Hyuga that you've been getting close to the Uchiha clan recently. Is that true?"

Kakashi paused, slowly turning around.

"Reporting to Lord Hokage, I did inquire about the Sharingan from the Uchiha, but my goal was to investigate the enemy who tried to kidnap the Nine-Tails Jinchuriki through Obito's Sharingan."

He explained to the Third Hokage respectfully and calmly.

"I see."

The Third Hokage nodded in understanding, thought for a moment, and still reminded Kakashi, "However, you must maintain a proper distance from the Uchiha clan as much as possible."

"Yes."

Kakashi responded again, like an emotionless scarecrow.

He then left.

Puff.

The Third Hokage took a puff from his pipe, his eyebrows furrowed.

What's been going on recently?

First, someone tried to kidnap the Nine-Tails Jinchuriki, then there was the murder of the police force members.

Were these two cases related?

But one thing was certain.

Many unfriendly "guests" had come to the Leaf Village recently.

The Third Hokage had a bad feeling that some plot against the Leaf Village was brewing in the shadows and was about to unfold.

The only good news.

Was that the internal problem of the Uchiha clan had temporarily settled down. They had been behaving recently, not giving him, the Hokage, any more worries.

In this case.

The most urgent task was to catch the criminals who had murdered the police force members.

However.

Unexpectedly.

Two days passed, and the Leaf Village side had no leads. The criminals seemed to have disappeared suddenly.

This was undoubtedly a major blow to the newly established police force.

Although it didn't completely ruin the reputation of the police force, it did lose a lot of prestige, leading people to question the ability of the police force, especially the Hyuga clan.

At this, Hiashi Hyuga's face was

extremely grim.

Uchiha Clan Compound.

While the village was in an uproar over the murder of the police force members, the Uchiha clan remained behind closed doors, living their own lives.

The Uchiha clan had no interest in the affairs of the Leaf Village.

These days.

The busiest place in the clan was the newly established Uchiha Physical Enhancement Department. Every day, from morning to night, groups of clan members were coming and going.

A fitness craze had swept the entire Uchiha clan.

Samui was extremely busy these days.

During the day, she was a fitness instructor at the Physical Enhancement Department, diligently guiding hundreds of students;

At night, she didn't forget her original mission, becoming a spy again, staying up late to sort out intelligence and send it back to the Cloud Village.

During this period, Samui received a reply from the Hidden Cloud Village, revealing an important piece of news.

Next month, the Leaf Village would hold the Chunin Exams.

Since the Hidden Cloud Village had signed a peace treaty with the Leaf Village three years ago, they naturally found an excuse to participate this time, led by the Fourth Raikage himself, with the aim of testing the strength of the Leaf Village.

If everything went as expected.

After the Chunin Exams, Samui could end her three-year spy mission, return to the village with the Hidden Cloud team, and take on more important duties.

The thought of being able to go home soon made her overjoyed, even causing her to lose sleep.

She missed her hometown and her younger brother Atsui, whom she hadn't seen in three years.

But after calming herself down.

Samui lowered her head, touched the crystal necklace on her chest, and a hint of inexplicable loss and reluctance flashed in her sky-blue eyes.

Late at night.

Uchiha Medical Room.

Under the bright light, five people gathered, namely Dan, Fugaku, Shisui, Tsunade, and the carefree Aoi.

They could be said to be the five major forces of the Uchiha faction at the moment, each possessing strength around the level of a Kage.

With these five people guarding the Hashirama cells, neither Obito and Akatsuki's people, nor the high-ranking officials of the Leaf Village, could take them away.

After several days of research.

Tsunade had gained a fairly deep understanding of the theory and process of transplanting Hashirama's cells, but during this process, she also discovered some problems.

According to Uchiha Madara's self-account in his experimental notes.

He bit off a piece of Hashirama Senju's flesh and grafted it onto himself, thereby gaining the power of the Senju clan. This power combined with his own Uchiha power to form the power of the Rinnegan, eventually awakening the Rinnegan.

Previously.

Tsunade never imagined that the once rival clans of Senju and Uchiha could merge their powers. Moreover, tracing back a thousand years, they even shared the same ancestor.

That was the legendary Sage of Six Paths.

She was shocked for a long time after learning this and couldn't recover.

If the Senju and Uchiha truly shared an ancestor, why did they fight relentlessly for a thousand years as once family?

Neither Tsunade, as a Senju, nor Fugaku and Shisui, as Uchihas, could understand this.

Dan knew the reason was due to Black Zetsu's instigation, but he didn't bother to explain.

His focus was only one thing.

Could they proceed with the transplantation of Hashirama's cells immediately?

To this.

Tsunade's answer was that she could perform the transplantation surgery for the Uchiha, but she couldn't guarantee the success rate.

Because.

The greatest risk of transplanting Hashirama's cells was a strong rejection reaction.

Even though Tsunade was hailed as the legendary medical ninja, she could only use various methods to alleviate this rejection reaction as much as possible, but she couldn't make it disappear completely.

And given the domineering nature of Hashirama's cells, even a slight rejection reaction could be fatal.

This had been confirmed by the Leaf Village's previous research.

After hearing Tsunade's words.

Fugaku and Shisui both looked serious, realizing that they had been too optimistic about the Uchiha's transplantation of Hashirama's cells.

But Dan had a different opinion.

"I believe there will be no problems at all," he stated decisively.

"Why?" Tsunade couldn't help but frown, crossing her arms and waiting for his answer.

Dan gave his reason.

"If other people were to transplant Hashirama's cells, it would indeed be more likely to fail than succeed, but not necessarily for the Uchiha.

Whether it's the records on the Uchiha clan's stone tablet or Madara's personal experience of awakening the Rinnegan, they all prove that the Uchiha and Senju share the same origin and have the same blood in their bodies.

The two clans are actually one, only one inherited the Sage of Six Paths' Yin power, and the other inherited his Yang power.

Since they are family, the rejection reaction from the Uchiha transplanting Hashirama's cells will definitely be much milder.

The successful transplantation examples of Madara and Obito have already proven this."

Makes sense.

Upon hearing this, Fugaku and Shisui both nodded thoughtfully.

If Dan's speculation was correct, it meant that most of the Uchiha clan members had the opportunity to successfully transplant Hashirama's cells and obtain the Yang power of the Senju clan.

At that time.

It was unimaginable how powerful the Uchiha clan would become!

"I have a hypothesis."

Dan looked at the expressions on their faces and continued:

"According to the principle of Yin-Yang harmony, the stronger the Yin power, the better one can adapt to Hashirama's cells, which contain Yang power, like Uchiha Madara.

The most direct manifestation of Yin power in the Uchiha clan is the

Sharingan.

So, I believe that from the regular one-tomoe, two-tomoe, to the three-tomoe Sharingan, the stronger the ocular power, the smaller the risk of transplanting Hashirama's cells.

And for Uchiha who have awakened the Mangekyou Sharingan, the success rate of transplantation must be one hundred percent!"

Upon hearing this, everyone present was visibly moved.

Because, among those present, there were three Uchiha with the Mangekyou Sharingan.

"What you're saying seems to make some sense, but it still needs to be tested in practice to truly prove it."

Tsunade stared at Dan, her gaze sweeping over the three Uchiha present.

In other words, who's going first?

"Let it be me."

Fugaku made up his mind and stepped forward.

As the clan head of the Uchiha, if he didn't step up now, who would?

A clan head should set an example for his people, bear the risks, and seek benefits for the clan with his own sacrifice.

Moreover.

Due to his frequent use of Susanoo recently, Fugaku had clearly felt a decline in his ocular power and vision. To solve this problem, he had no choice but to transplant Hashirama's cells.

There was no other choice.

Shisui's face changed, thinking that Fugaku was too impulsive, and tried to persuade him, "Clan head, why don't we wait a bit longer..."

"We can't wait any longer."

Dan directly interrupted Shisui's words, saying seriously, "Although we have temporarily eased our relationship with the Leaf Village, the Uchiha are likely being targeted by the more dangerous Akatsuki organization now. At this time, we need to seize the time and improve our strength as soon as possible."

He had been persuading for a long time.

His real purpose was to push Fugaku out to be the guinea pig to see if there would be any mishaps.

After all, Dan would never risk his own body.

"Dan is right."

Fugaku nodded, deeply agreeing with his brother-in-law's words.

So, he solemnly requested Tsunade:

"Please perform the transplantation surgery for me. I will bear any risks that occur during this period and will not blame you."

Tsunade was silent for a moment, and finally, with a serious look, she nodded:

"Alright."

She also wanted to see with her own eyes whether Dan's speculation was correct and what changes would occur after the Uchiha obtained the power of the Senju.

Could they really give birth to the so-called power of the Rinnegan?

While Tsunade was preparing for Fugaku's surgery.

On the outskirts of the Leaf Village, in a secluded forest where no one was around.

Whoosh.

With a vortex-like fluctuation in space, Obito appeared, meeting Orochimaru and Sasori who had been waiting here for a long time.

Akatsuki was about to take action.
