Tobirama, Be Good and Obey Me.

Uchiha Nan scanned Tobirama Senju with greedy eyes, like an old farmer looking at crops about to be harvested.

What's the most expensive thing in this Ninja world?

That's definitely a talented person!

How could Tsunade, who owed so much money, still live a carefree life? It's because she mastered core technology—incredibly powerful Medical Ninjutsu.

The creditors wouldn't press too hard for any of her debts; after all, every family has someone seriously ill. As long as Tsunade is there, it's like having an extra life!

The big investors behind those gambling dens were more than happy for Tsunade to owe them more money; the more money she owed, the more favors they could gain.

As for the debt, it's just a matter of extending the repayment period. Tsunade will pay it back sooner or later; they only have one life.

The Tobirama Senju before me is even stronger than Tsunade; all the powerful forbidden techniques that can be considered top-tier in the Ninja world originated from him.

The Fourth Hokage's signature technique, the Flying Thunder God Technique; the Impure World Reincarnation that ignited the Fourth Great Ninja War; and Naruto Uzumaki's Multiple Shadow Clone Technique.

Besides, Tobirama's primary job has always been Hokage, and these forbidden techniques were invented by him in his spare time. I must imprison Tobirama in the Uchiha clan's territory and make him do scientific research Tenten.

"What do you want to do?!"

Tobirama Senju felt Uchiha Nan's burning gaze and instinctively sensed a malice, as if Uchiha Nan wanted to do something bad to him.

What do I want to do?

"Tobirama, you are now my prisoner. I have complete control over your body, so I can do whatever I want with you."

Hehehe

Uchiha Nan revealed a perverted smile.

"I'm warning you, don't do anything reckless!"

Tobirama Senju was a little flustered. He seemed to have seen this situation before. He seemed to have said the same thing when he used prisoners for scientific experiments.

But does Uchiha Nan even know what scientific research is?

The Uchiha's talent has always been focused on combat!

"Tobirama, you should just give in to me."

"After all, everything I've done is for Konoha."

"Stop spouting nonsense. Just tell me what you want me to do!"

Tobirama Senju couldn't stand Uchiha Nan Uchiha Nan's strange and suggestive words, and told him to just say what he meant.

"That means having you work for me, and putting all your energy into scientific research."

"To be honest, Tobirama- sama, every day you're in the Hokage position is a complete waste of your life. A talent like you should be spending your days doing scientific research; otherwise, you're a loss to the entire Ninja world!"

Uchiha Nan highly praised Tobirama Senju's research abilities, and thought that letting Tobirama Senju become Hokage was a waste of his time and a loss to the entire Ninja world.

If Tobirama Senju had devoted even a little time and energy to improving productivity, the technological trees for steel, food, electricity, and so on would have been fully developed long ago.

For someone capable of inventing a miraculous Ninjutsu like the Impure World Reincarnation, these things were simply a piece of cake for Tobirama Senju!

Do you really think so?

Tobirama Senju's eyes lit up; Uchiha Nan's undisguised praise made Tobirama Senju's vanity soar.

He actually developed a feeling of kinship with Uchiha Nan.

Suddenly, the evil brat from the Uchiha in front of me wasn't so annoying anymore; I discovered what I was most proud of.

It's such a pity that the person who appreciates my scientific research the most in this world is actually the evil brat from the Uchiha Clan. The Senju Clan members are only focused on developing their clan's power and are only interested in the position of the Third Hokage.

Even his older brother was advising him to stop doing those strange experiments and focus more on the development of Konoha.

Every time he invents a powerful forbidden technique, his older brother always asks first if it's Water Release. If not, he proactively writes it into the Forbidden Scroll and tells him not to reveal it.

They claim that these forbidden techniques are powerful and harmful to nature, and that passing them on to the ninjas of Konoha would do them no good whatsoever—this is utterly absurd.

"Of course, Lord Tobirama, you are the greatest scientist in the Ninja world!"

"Especially the Ninjutsu you invented to deal with the Uchiha, every strike is practically pushing the Uchiha to their doom."

"The Sharingan of the Uchiha possesses terrifying insight and Genjutsu abilities, so you invented the Bringer-of-Darkness Technique; the Sharingan can see through the Clone Technique, so you invented the Shadow Clone."

"Once you awakened the Mangekyō Sharingan and could summon Susanoo, you invented the Impure World Reincarnation and the Mutually Multiplying Exploding Tags Technique to wage a war of attrition!"

"With your unparalleled research capabilities, you can accelerate your research progress at will as the Uchiha's strength increases. Who in this Ninja world can rival you?"

Uchiha Nan decided to use examples to illustrate his point.

Uchiha Nan flipped through the Forbidden Scroll and discovered that Tobirama Senju Uchiha constantly updating his research results, inventing corresponding Ninjutsu to counter the Uchiha's strengths at each stage of their power.

When it comes to dealing with the Uchiha, no one in the entire Ninja world is more professional than Tobirama Senju. However, this professionalism is so terrifying that Uchiha Nan, who is also Uchiha, will definitely have to find a new profession for Tobirama Senju in the future!

"Forehead"

Tobirama Senju's initial goodwill towards Uchiha Nan vanished instantly. The praise was tinged with sarcasm, Tobirama Senju couldn't tell whether Uchiha Nan was praising him or using the conversation to mock him.

"Hmph, I'll take that as a compliment."

Tobirama Senju snorted coldly, and began to make plans in his mind.

If it's just about helping this evil Uchiha brat with his research experiments, then cooperating with him is an option.

If the bet Uchiha Nan mentioned was simply that he would occasionally Impure World Reincarnation by Uchiha Nan to take a look at Konoha under his rule, then his plan to escape is probably a long way off.

If I continue to help Uchiha Nan with his research, I can stay in the human world forever. As long as I continue to exist in the form of Impure World Reincarnation, I will definitely have a chance to sneak out.

Moreover, his research would ultimately be used by Uchiha Nan to strengthen Konoha's power. No matter how you look at it, cooperating with Uchiha Nan would be a sure win!

I still had so many experiments left to do before I died. I really miss the days I spent at the lab bench.

In the past, they either couldn't afford to conduct experiments because they were too poor, or they didn't have time to do experiments because they were busy with Konoha's official duties.

Pure and rational scientific research experiments are much more interesting than fighting and killing; consider it a vacation for yourself.

However, he couldn't just give in to this evil brat from the Uchiha so easily.

We must negotiate terms; we can't let him work for free!

"You mean you want me to do your research?"

"Let me tell you, I am the Second Hokage, and I have invented countless Ninjutsu in my lifetime. Moreover, you usurped the Hokage Position from Konoha. We are mortal enemies."

"So if you want me to work for you, my pay is very high!"
