As an Uchiha I became the Jinchuriki of Senju Tobirama

Did Sarutobi Hiruzen know that Senju Tobirama has been experimenting on humans?

Of course he knows!

Did he know how far Tobirama's limits went?

Of course he knows!

After becoming the Hokage, Sarutobi Hiruzen read the research records of Senju Tobirama many times, as well as those semi-finished products, and he deeply believed that what the first Hokage did was right.

Those techniques should be banned!

Unrestrained imagination is not enough to describe Tobirama's thinking. If you want to make a fair evaluation, it should be called contempt for life and death and no bottom line...

Sarutobi Hiruzen also used Senju Tobirama as an example in private, telling Orochimaru not to be so extreme, just absorb his scientific research ideas, but not to follow him recklessly, otherwise it would be bad...

But in front of Uzumaki Mito, Sarutobi Hiruzen cannot make a critical evaluation of his sensei as he did in front of Orochimaru...

But looking at Uzumaki Mito's oppressive eyes, Sarutobi Hiruzen quickly searched for words in his mind...

Sarutobi Hiruzen put on a confused but wise look and said carefully: "Well... Tobirama-sensei... devoted a lot of time to the study of ninjutsu... and his research was... quite varied."

Mito laughed softly, interrupting him: "That's not what I'm asking, Hiruzen, I want you to evaluate the scale and bottom line of Tobirama's research..."

Sarutobi Hiruzen's eyes became more blurred, and at this moment, he even felt that Uzumaki Mito was making fun of him.

But there was no way, Uzumaki Mito seemed to want to hear his answer.

Hiruzen complained helplessly in his mind. After pondering for a long time, he had an idea.

"Tobirama-sensei... In his experiments, he was always guided by the will of fire. His research into forbidden ninjutsu... saved many resources, enriched the village's knowledge, and benefited education and future wars... he always had a vision ahead of his time..."

"Monkey, you know that's not what I'm asking..." Uzumaki Mito looked at the sweaty Sarutobi Hiruzen with a playful look and laughed. "Hiruzen, can't you tell the truth?"

Hiruzen smiled awkwardly, his lips trembling.

Some things Mito could say, but he, as a disciple, couldn't really...

What if Tobirama's soul was watching him from the Pure Land...?

At this point, Tobirama was already a little annoyed.

Although he couldn't see Sarutobi Hiruzen's expression, his tone said it all!

What, are my human experiments really too much?

That's just because my elder brother has no vision and my sister-in-law is too conservative, otherwise I would have developed a powerful forbidden technique to protect the future peace of Konoha!

Come on, Monkey! Can't you defend your sensei a little?

Senju Tobirama was very dissatisfied.

Tsunade watched this scene silently and couldn't help but admire Sarutobi Hiruzen's language skills.

"Tobirama... since I met him, I knew he had a special personality..." Uzumaki Mito still sighed, her old voice full of memories. "Before him, shinobi still used kunai and long swords to chop, used simple fire, wind, and thunder to attack, and then used earth and water to defend..."

"But after he invented the Shadow Clone Technique, the shinobi world seemed to wake up, and ninjutsu can be developed..."

"I still remember that we were fighting against the Uchiha clan at that time. Tobirama didn't know how to get those corpses, and used the Impure World Reincarnation to summon the dead members of the Uchiha clan, and let them pretend to be ghosts to talk to those Uchiha who missed their relatives..."

Sarutobi Hiruzen swallowed his saliva, he had already thought of what would happen next.

Tsunade frowned, although the second grandfather was warm, would he be so kind to the enemy?

"After that, when they were chatting happily, Tobirama detonated the multiplication explosive tags in the bodies of those Uchiha clans, and blew them into ashes..."

Uzumaki Mito seemed to be nostalgic.

"At that time, Uchiha Madara went crazy, Uchiha Izuna also went crazy, and all the shinobi of the Uchiha clan swore to kill Tobirama, but in the end they failed."

"After the village was built, Tobirama became the Hokage and suppressed the Uchiha clan..."

Uzumaki Mito looked at Tsunade's shocked expression and laughed.

"Little Tsuna, your second grandfather is just gentle to you..."

"He has the reputation of being the fastest in the shinobi world, but he is also called the most despicable demon of the Senju by the Uchiha clan..."

"Do you want to hear more? There are many stories like this about Tobirama."

Even inside Kazuki's body, Tobirama couldn't hold back any longer!

Senju Tobirama was sulking, and couldn't help thinking that if Kazuki was awake, he would definitely support and understand him!

Uzumaki Mito looked at Tsunade's embarrassed expression and Sarutobi Hiruzen's awkward smile and shook his head.

"I just saw this boy, Kazuki, and it reminded me of Tobirama's old days. When one gets older, one tends to remember things from the past. I hope you can understand."

Then, her expression became more serious.

"Now, I want to talk about why Kazuki lost control, why he suddenly used Tobirama's Flying Thunder God Technique, and even possessed his chakra. He is an Uchiha, but he has mastered the Uzumaki clan's Adamantine Sealing Chains!"

Tobirama blinked, didn't he manage to fool his sister-in-law? But how could the Adamantine Sealing Chains be related to me?

For the Adamantine Sealing Chains awakened by Kazuki, Senju Tobirama believed that it was the work of Uzumaki Mito.

After all, Kazuki has been learning sealing techniques from her in recent months.

And Uzumaki Mito's performance also seemed to have noticed something, often secretly sensing Kazuki and transferring some chakra into Kazuki's body...

Senju Tobirama pondered.

Sarutobi Hiruzen and Tsunade listened seriously.

Uzumaki Mito sighed and gave the final answer: "Kazuki... is the final result of Tobirama's forbidden techniques."

"You all know how wary Tobirama was of the Uchiha clan. An Uchiha with great talent, even for someone as extraordinary as Tobirama, was nearly impossible to defeat."

"When he was alive, Tobirama himself could suppress him, but after his death..."

Uzumaki Mito looked at Sarutobi Hiruzen and said softly: "If there is an Uchiha Madara in the Uchiha clan... forget it, there is a shinobi like Uchiha Izuna, how should you deal with it?"

Sarutobi Hiruzen frowned, an Uchiha who can fight with his sensei for a lifetime...

Would that mean he would have to face off against Senju Tobirama?

Just thinking about it, Sarutobi Hiruzen felt a palpitation, that is definitely an extremely terrifying opponent!

Uzumaki Mito looked at Sarutobi Hiruzen's unconfident expression and shook his head.

Sarutobi Hiruzen has tried his best. As a ninja who is not a Senju or Uchiha, his talent is already versatile enough.

But when facing those real monsters, it is still not enough.

Tsunade, on the other hand, was completely confused. What did her second grandfather's forbidden techniques have to do with Kazuki?

"So, in order to solve this problem, Tobirama came up with a solution, which is Kazuki..."

"Tobirama developed a certain forbidden technique, using his own chakra as the main body and combining it with the chakra of the Uzumaki clan to ensure that the Uchiha clan is completely suppressed..."

Uzumaki Mito looked at Kazuki, and at this moment, his eyes seemed to be shocked by Tobirama's boldness.

"Taking advantage of this, Tobirama also mixed in Uchiha Izuna's chakra and eventually formed a chakra aggregate, which attached itself to Kazuki's body, creating something akin to a second Nine-Tails for Konoha..."

"You probably can't sense it, after all, you haven't seen Uchiha Izuna, but I can recognize that pupil power, and my perception will not be wrong..."

Sarutobi Hiruzen was stunned when he heard it, and Tsunade was even more so, her mouth couldn't close.

But thinking about it, Sarutobi Hiruzen realized that if it was Senju Tobirama, these things made sense, especially since he, as Hokage, knew some of Tobirama's forbidden techniques that were never revealed.

"It's like Tobirama-sensei's artificial tailed beast project…" Sarutobi Hiruzen muttered to himself. "I saw in the texts left by Tobirama-sensei that he tried to create a chakra conglomerate from negative energy, which he called the Zero-Tails Beast, like the second Tailed Beast of Konoha..."

"But it seems that he ran into some obstacles..."

Uzumaki Mito nodded. "That's right, Monkey, Tobirama's technique was banned by Hashirama at that time."

"But looking back on it now, it seems that Tobirama didn't give up. Instead, he took a more extreme path to create a new forbidden technique, both to resolve the threat of the Uchiha clan and to give Konoha a second tailed beast."

"And the result of this technique is Kazuki..."

Tsunade was completely lost and muttered: "But why didn't Second Grandpa tell us?"

Uzumaki Mito sighed.

"Perhaps, it's because Tobirama didn't expect that he, a Flying Thunder God Technique user, would be surrounded and killed one day. Perhaps, Hashirama and I suppressed his ideas too much, so he had to conceal it..."

"But in any case, at least I've discovered the truth before Kazuki is misunderstood, and we still have time to fix things."

Hiruzen bowed his head in regret. In this way, the reason why Kazuki's affairs are so confusing, is essentially caused by Tobirama's death to protect them...
