"Make Uchiha Izuna your subordinate?"
"Tobirama, you really are…"
After hearing Senju Tobirama's request, the corner of Uchiha Ren's mouth twitched.
He hadn't expected Tobirama to have such an idea.
So many years had passed, yet he still couldn't forget his old rival, Uchiha Izuna.
He really was just like Senju Hashirama!
"You agree?"
Senju Tobirama's face lit up with joy.
He had wanted this for a long time.
This naturally evil Uchiha brat in front of him didn't take him seriously at all.
Every day, Ren treated him like livestock.
And Tobirama had no way to resist.
But once Uchiha Izuna was revived through Impure World Reincarnation, whenever Uchiha Ren oppressed him, he would oppress Uchiha Izuna in return.
All the anger he suffered from Uchiha Ren would be vented onto Uchiha Izuna.
He would make Uchiha Izuna serve him tea, massage his legs, wash his clothes, and beat his back!
Just thinking about that feeling was…
Wonderful!
In Senju Tobirama's mind, he imagined Uchiha Izuna serving him with a resentful, disgusted expression.
No matter how unwilling Izuna was, he would still have to obey Tobirama's orders!
Thinking of this, Senju Tobirama couldn't help humming softly.
"Hey, hey, Tobirama."
"What kind of perverted scene are you imagining in your head?"
"Why did your expression suddenly become so obscene?"
Seeing Senju Tobirama's lips curl as he sank into fantasy, Uchiha Ren felt a chill crawl over him and quickly interrupted.
This naturally evil white-haired old ghost was definitely imagining something strange!
"Cough, cough… nothing."
"Uchiha Ren, then this matter is settled?"
Senju Tobirama's tone was somewhat impatient.
He could no longer wait to see Uchiha Izuna's expression after being revived by Impure World Reincarnation.
It would definitely be very interesting!
"Tobirama, you know this."
"I am a member of the Uchiha Clan, and the current clan head of the Uchiha."
"Uchiha Izuna is an elder predecessor of the Uchiha Clan!"
"He weathered wind and rain for the family, and later encountered a villain's sneak attack—cough, cough."
"In short, although I have never met Uchiha Izuna, I have always held great respect for him in my heart."
"No matter what, Uchiha Izuna is my beloved friend, my dearest brother!"
Uchiha Ren spoke with deep emotion.
Senju Tobirama merely snorted coldly.
Others might not understand Uchiha Ren.
But how could he not understand this black-hearted bastard?
Uchiha Ren had never even met Uchiha Izuna.
What feelings could he possibly have?
Now that he was spouting so much nonsense, he was definitely trying to squeeze benefits out of him.
Add money!
As long as the benefits were sufficient, there was nothing Uchiha Ren wouldn't dare do.
What was one mere Uchiha Izuna?
"Those two humanoid creatures you sent over… they're called White Zetsu, right?"
"Through my recent research, I've obtained some interesting results."
Senju Tobirama decided to bring out something real to exchange for the chance to revive Uchiha Izuna through Impure World Reincarnation.
"Oh? Tell me in detail."
Uchiha Ren became interested.
He hadn't expected an unexpected harvest from this trip to the underground laboratory.
"According to my research, those White Zetsu were once human beings."
"Someone used a unique method to transform them into their current state."
After hearing this, Uchiha Ren picked his ear, his expression showing no surprise at all.
He had known this information for a long time.
Humans were hung on the Divine Tree, then drowned in beautiful dreams.
Their bodies were slowly transformed by the Divine Tree until they finally became White Zetsu.
"And?"
"I already knew that."
"Why are you so impatient? Let me finish!"
"White Zetsu cells are similar to my elder brother's cells."
"Both possess extremely vigorous vitality."
"But White Zetsu cells are far less invasive than my elder brother's cells."
"They can even neutralize the invasiveness of my elder brother's cells."
"But that isn't the most important part."
"The functional potential of White Zetsu cells is especially strong!"
"In the past, producing one vial of Hashirama cell solution was extremely expensive."
"Although the cells of your Uchiha Clan can resist the invasiveness of Hashirama cells, when the two types of cells collide, the stimulation is extremely intense."
"It's just like the relationship between the Uchiha Clan and the Senju Clan in the past—completely incompatible."
"It requires expensive auxiliary medicines to act as stabilizers."
"But now, with White Zetsu cells, there may be an opportunity to achieve mass production of Hashirama cell solution."
"The effect will be weaker than the current version, but it will still be powerful."
"It can greatly enhance a shinobi's potential, especially chakra reserves and recovery ability."
Senju Tobirama revealed his latest discovery.
Uchiha Ren's eyes lit up.
"Doesn't that mean we can raise the lower limit of Konoha's shinobi, increase their upper limit, and even turn ordinary people who lack the talent to become shinobi into shinobi?"
Excitement colored Uchiha Ren's voice.
In this ninja world, the number of shinobi compared to the entire human population was pitifully small.
The situation was somewhat similar to metahumans in Under One Person.
Only, the gap between the top experts of the two worlds was enormous.
Metahumans couldn't rule the world.
But shinobi could.
Top-tier shinobi could summon meteorites with one hand, or even cleave the moon apart with a single strike.
"Theoretically, yes."
"But I have to remind you."
"The degraded mass-produced version of Hashirama cell solution cannot transform people completely."
"It can only allow ordinary people to extract chakra and become ordinary genin."
"In the best case, through continuous training and cultivation, reaching chunin-level combat power would already be quite good."
Seeing Uchiha Ren's excitement, Senju Tobirama hurriedly added a warning.
He could not mass-produce high-end jonin combat power.
Every jonin in Konoha was extremely precious.
They possessed excellent talent, endured harsh training, and often had to experience life-and-death battles before becoming qualified jonin.
If he didn't warn Uchiha Ren ahead of time, Ren might develop unrealistic expectations.
And when the time came, Uchiha Ren would definitely fall out with him.
Maybe he would even let that naturally evil Uchiha Izuna ride on his head and throw his weight around.
That would be hell.
One Uchiha riding over him was already the limit of Senju Tobirama's endurance.
He had no desire to challenge his own limits.
"That's enough!"
"Genin and ordinary people can already be considered two different species."
"The difference in work efficiency is heaven and earth."
"In Konoha's factories, the outstanding groups and outstanding workers—the backbone members—are all shinobi."
"When the time comes, if every worker in Konoha's factories is a shinobi…"
"Wouldn't I be able to stand up and exploit them—cough, cough."
"I mean, allow them to contribute even more diligently to Konoha!"
"Even in a war of attrition between ninja villages, we could completely mass-produce genin to serve as cannon fodder."
"Of course, I would never do such inhumane things."
"Killing one genin only takes a single shuriken."
"But cultivating one genin from birth to adulthood takes more than ten years."
"It's better to let them shine in factories for decades."
"Let them earn their retirement money while they're young, then enjoy their blessings after retirement!"
"Konoha's hospitals also need to generate revenue."
"This is truly… truly wonderful!"
Uchiha Ren felt he was very compassionate.
He had always maintained reverence toward life.
Even though he possessed a forbidden technique like Impure World Reincarnation, he would not use it lightly.
After all, the Pure Land was watched over by the Sage of Six Paths.
Once Pandora's box was opened, and combined with the wild beast called capital, it would definitely be abused without restraint.
When that happened…
His ending would be hard to describe.
Beast.
Watching Uchiha Ren put on a sorrowful and compassionate expression, Senju Tobirama cursed inwardly.
This bastard was still as black-hearted as ever.
"Tobirama, how long will it take to develop this version of the Hashirama cell solution?"
"As soon as possible."
"For the prosperity of all Konoha, I want more ordinary people to become shinobi and enjoy Konoha's blessings!"
"Shortest case, half a year to one year."
"Longest case, three to five years."
"You know this yourself. When I researched Hashirama cell solution, it took me a year."
"And that was on the foundation of previous experiments."
"Although there are some small results now, the scientific difficulty hasn't decreased much."
"Besides, scientific research requires inspiration."
"Forget it. Even if I explain it to you, you won't understand."
Senju Tobirama's tone overflowed with superiority.
He stood on the high ground of intellect, looking down at Uchiha Ren.
Even if Uchiha Ren was good with words, he couldn't refute this.
Damn it. He really managed to show off.
Looking at Senju Tobirama's smug face, Uchiha Ren felt somewhat annoyed.
But he did not reveal his displeasure.
This was Senju Tobirama's capital for arrogance.
One had to respect scientific talent.
One had to respect technology.
"What if Orochimaru joins?"
"Orochimaru's talent and brilliance aren't inferior to yours."
"If the two of you conduct research together, it should speed things up, right?"
"Hm?"
"Orochimaru?"
"Haven't you always refused to let Orochimaru touch human experimentation?"
"Why the change?"
Senju Tobirama was somewhat puzzled.
From the moment Uchiha Ren introduced Orochimaru to him, he had repeatedly warned him—
Absolutely do not let Orochimaru come into contact with human experimentation.
"At first, it was because he was still young."
"If he touched human experimentation too early, I was afraid he would go down an evil path, or even start modifying his own body."
"You know what state he was in when he first encountered research. He was practically possessed."
"But now, I think the time has come."
"And I don't believe you haven't secretly let Orochimaru touch human experimentation behind my back."
"I saw that you were controlling the scale, so I didn't expose you."
"You didn't actually think I didn't know, did you?"
"Orochimaru's relationship with me… hmph."
"Even if you're his teacher, it doesn't matter."
"After all, I am his benefactor, his direct superior, and the Hokage of Konoha."
Uchiha Ren wore a proud expression, his tone carrying faint arrogance.
Your disciple Orochimaru has always been close to me.
His relationship with me is even better than with you, his teacher.
"Bastard!"
Senju Tobirama's expression turned ugly.
He had raised a ghost in his house and hadn't even known it!
"Uchiha Ren, don't get smug."
"Orochimaru is a good seedling."
"Because you kept nagging beside my ear, I never let him come into contact with true scientific research."
"Those so-called daily-life ninja tools you value are nothing but minor tricks!"
"I will lead Orochimaru into true research."
"Human experimentation."
"Forbidden technique research."
"Even the mysteries of the soul!"
"When he first entered research, Orochimaru's vision was still narrow."
"When he saw me, it was like a frog at the bottom of a well looking up at the moon."
"But once he comes into contact with true research, seeing me will be like a mayfly beholding the blue sky!"
Senju Tobirama snorted coldly.
Once Orochimaru witnessed true scientific research, he would view Tobirama with reverence like a god.
What was Uchiha Ren compared to that?
Just a naturally evil Uchiha brat!
"You're impressive."
"Then what about the research progress?"
"Can it be accelerated?"
Uchiha Ren waved his hand indifferently.
He only cared about when the degraded mass-produced version of Hashirama cell solution could be completed.
This made Senju Tobirama extremely unhappy.
It felt as if his counterattack had landed on cotton.
"Shortest case, half a year to one year."
"Longest case, three to five years."
Senju Tobirama repeated his earlier answer.
"Orochimaru has no effect at all?"
"I don't believe that."
"I'm not satisfied with this timeframe."
"You need to give me a new number."
Uchiha Ren saw through Senju Tobirama's attempt to negotiate conditions.
But he would not indulge him.
This naturally evil Senju old ghost would open a dye workshop if given just a bit of color.
Climbing up the pole when given a chance was his passive skill.
"At Orochimaru's current level, he can at most serve as my assistant."
"The core research difficulties still need me to overcome them."
"You know this too. Scientific inspiration is extremely important."
"If inspiration comes one day, perhaps I can shorten the research time to about a year, or even less."
Senju Tobirama's meaning was obvious.
He needed Uchiha Izuna to serve him like livestock and become a source of scientific inspiration.
"Say it, then."
"How can you burst with scientific inspiration?"
Uchiha Ren sat back down on the sofa, crossed one leg over the other, and looked at Senju Tobirama.
"For example, let Uchiha Izuna become my subordinate."
Senju Tobirama stated his wish once again.
"Hmph. Hmph."
Uchiha Ren snorted coldly a few times.
This naturally evil white-haired old ghost really had not given up.
If he revived Uchiha Izuna through Impure World Reincarnation, there must be some extremely filthy and disgusting idea hidden in his heart.
"Tobirama, do you know who Uchiha Izuna's elder brother is?"
"Uchiha Madara."
"And do you know where Uchiha Madara is right now?"
"He's in Konoha."
"Are you trying to make Uchiha Madara blow Konoha into the sky?"
"If Uchiha Izuna escapes this laboratory and lets Uchiha Madara learn that Konoha is playing with the soul of his most beloved younger brother…"
"I can guarantee that Uchiha Madara will turn Konoha into ruins!"
Uchiha Ren roared angrily at Senju Tobirama.
"What's there to fear?"
"This laboratory has three layers inside and three layers outside, all sealed with sealing techniques you personally engraved."
"Even I can't escape!"
"And we can simply use an ordinary person as the sacrifice to revive Uchiha Izuna through Impure World Reincarnation."
"He won't even be able to display one percent of his strength."
"When the time comes, I'll assign three clones to monitor him constantly!"
"Uchiha Izuna absolutely won't have any chance to escape!"
Senju Tobirama argued stubbornly with Uchiha Ren.
He absolutely did not believe Uchiha Izuna, revived in an Impure World Reincarnation state, could escape from this heavily sealed laboratory under his nose.
"Looks like you've considered everything very thoroughly."
Uchiha Ren said with a faint, ambiguous smile.
"Does that mean you agree?"
Senju Tobirama's expression was filled with surprise.
