Konoha: The thirty-year-old Uchiha is not motivated.

After some haggling, Nawaki finally secured the rental rights to the Fugaku Sharingan by paying the exorbitant price of eight strawberry milkshakes.

"Now that you've reached an agreement, I'm going to begin the surgery~"

Seeing that the two children had reached an agreement, Uchiha Gin nodded, signaling them to lie down on the spot. He was about to begin his professional procedures.

"Uh, Grandpa Yin, are you sure you don't want to wash your hands?"

Looking at Uchiha Gin's large hands covered in strawberry jam, Nawaki's brows furrowed deeply. He certainly didn't want to have strawberry-flavored eyeballs transplanted into him.

"Hey! It happened so suddenly, let's keep things simple. Just bear with it and grit your teeth and get through it."

Uchiha Gin straightened his face and reprimanded him with the air of someone who had been through it all.

"Tsk~ I really can't do anything with you guys, okay? I'll wipe it off, alright?"

Seeing the growing disgust on their faces, he had no choice but to turn around and rub his strawberry-jam-covered hands on the Hyuga brothers who were watching the show.

"Look, isn't it clean now!"

The Hyuga brothers, caught in this undeserved calamity, lowered their heads, looking at the red handprints on their snow-white kimonos, their four small fists clenched tightly.

"."

However, since they couldn't defeat Uchiha Gin, they could only stare wide-eyed at the culprit.

(°д°)(°д°)
"Um, before I get my eyes replaced, I'd like to ask something."

Seeing Uchiha Gin's large hand getting closer and closer to his eyes, a nervous Nawaki raised his hand again.

"If you have any other questions, please tell me all at once."

Uchiha Gin frowned impatiently. It's just a change of eyes, why make such a fuss?

Did you see any hesitation when Kakashi and Obito switched places? It was a plug-and-play, hot-swap game.
"After I get the Sharingan, will I be able to use genjutsu?"

"Isn't that obvious? That's why it's called a physical cheat code. Fugaku's illusion talent is pretty good. You've really struck gold."

Nawaki isn't lacking in illusionary talent; however, due to his age, his Yin Release nature hasn't awakened, making him quite helpless in the realm of illusion.
Fugaku was different. At a young age, he awakened the three-tomoe gem in one eye, and his spiritual energy far surpassed that of his peers. He could easily master illusion techniques.
His eyes were constantly generating Yin Release chakra, essentially acting as an ammunition depot storing vast amounts of Yin Release chakra.
Once Nawaki has Yin Release chakra, casting genjutsu will be a piece of cake for him.
"That's great! Let's change it quickly, I can't wait!"

Although Rope Tree only half understood what was being said, he believed that Grandpa Gin would never cheat him, so he immediately lay down on the sofa, his face full of eager anticipation.

"Uncle, after this guy gets my eyes, won't he be sucked dry?"

However, before Uchiha Gin could make a move, another party involved raised a question.

Fugaku blinked thoughtfully. As his birth eye, he was acutely aware of the terrifying energy consumption it consumed.
Even using it normally is a bit too much for me. If it were Rope Tree, I'm afraid the Sharingan would drain my energy the moment I opened my eyes.
"You can rest assured, this kid's physical strength is top-notch, he could withstand even if he had an arm or an eye replaced."

Nawaki wasn't some peasant like Kakashi; his Senju bloodline was extremely pure, and the physical energy consumed by his Sharingan to create Yin Release chakra was nothing more than a drop in the ocean for him.

"That"

"Alright, we can discuss any problems after we've paid it off."

Seeing Fugaku's worried expression, Gin Uchiha waved his hand, preparing to begin the simplest surgery in the Naruto world.

Nawaki and Fugaku lay head to head on the sofa, their faces scrunched up in tension.
"Hey, you better keep your word, eight cups, eight cups!"

Fugaku swallowed hard, trying to ease his anxiety by changing the subject.

"Eight cups it is, but it has to be paid in installments. My sister took all my allowance and I don't know what she did with it, so I can only buy you one cup every week."

Following the other person's lead, Rope Tree answered tremblingly.

"Huh? This is not what we said before. This is fraud!"

Upon hearing the word "installment payment," Fugaku's vision went black.
Uchiha Gin watched the two start bickering, his face full of satisfaction.
Is this what they call sworn brothers?
"Don't say anything, just get some sleep."

He was, after all, a licensed gynecologist, and would adhere to basic medical standards. To facilitate the surgery, Uchiha Gin used physical hypnosis on the two of them.
"Boom~"

"Boom~!"

Rope Tree's head seems a bit harder; no wonder he's such a hothead.

"Mikoto, you guys step aside for a moment, the following scene is going to be a bit bloody."

After putting on the medical gloves he took out of his backpack, Uchiha Gin turned to Mikoto and the Hyuga brothers, who were staring wide-eyed with curiosity, and said...

"Hmph! If you don't want me to see it, then you don't want me to see it."

Xiao Meiqin pouted and turned her head to the side.
"Can we cover our eyes?"

The Hyuga brothers spoke earnestly, while simultaneously extending their small hands to cover their eyes completely, leaving not a single gap.
This seemingly sincere act made Uchiha Gin roll his eyes in exasperation.

Do these two kids think he's an idiot?
"Before you say that, you should first tighten the veins in your temples."

With a wave of his hand, he tossed the three onlookers outside the shop, and Uchiha Gin rubbed his fists together in anticipation.

It's time to show the real technology!

"I hope that kid Nawaki can step up his game and help Fugaku increase the growth value of his Sharingan."

If you buy a car, you should drive it. What's the point of leaving it at home and filling up your tank with gas every year?
Uchiha Gin nodded thoughtfully, then reached out his wicked hand towards the two unconscious children.
"and many more!"

Just as his palms covered their eyes, Senju Hisama, who had been silent for a long time, suddenly spoke up, interrupting the deep green light emanating from Uchiha Gin's hands.

"What's wrong with you?"

Looking at Senju Hisama with displeasure, Uchiha Gin temporarily suspended the surgery.

"This is against the rules."

The test she set out to test her didn't mention anything about using physical cheats.

"This eye-swapping procedure just doesn't seem right, does it?"

"You didn't say it wasn't allowed, and isn't this basic ninja technique?"

Eye transplants, a minor surgical procedure, were far more common among ninjas than circumcisions.

After all, being a ninja is a high-risk profession. Losing limbs, going blind, or breaking limbs are common occurrences. Otherwise, the prosthetic limb shop at the village entrance wouldn't be doing such a booming business.
"No, this is not the power of the Rope Tree, it doesn't count."

Senju Hisami shook her head solemnly; no one understood the Sharingan's power better than her.
She worried that once Nawaki was infected, he would never be able to get rid of it and would eventually become a slave to the Uchiha's power.
"Tsk, why didn't you say so earlier? You made me waste so much time, and there's also a pair of gloves."

"It's quite interesting to watch the two of them talk."

It wasn't that Senju Hisa deliberately didn't say anything, but rather that she could directly sense the budding bond between Nawaki and Fugaku, which made her reluctant to interrupt.

"You think you can make a fool of me? Reimburse me, one million taels!"

Uchiha Gin, cursing, took off the medical gloves he'd stolen from the hospital and threw them in front of Senju Hisama.
"Do you take me for a traitor?"

"I don't care, my throwing knives are expensive, I charge money as long as you wear gloves."

Do I look like I'm worth a million?

Those who have nothing to lose are fearless. The current Senju Hisama is completely empty-handed and doesn't care about Uchiha Gin's accusations at all.

"As expected of the naturally despicable Thousand-Handed White Hair, it's no wonder that the Thousand Hands have been scattered with you around."

Seeing Senju Hisama's impervious attitude, Uchiha Gin trembled with rage.

"Why are you, a grown man, arguing so much?" Senju Hisa, who had unconsciously adapted to her female identity, not only failed to reflect on her reneging on the debt, but instead began to practice her boxing with surprising skill.

"You don't seem to care now."

Uchiha Gin pursed his lips. It seemed the feminization process was progressing well; in a few years, this white-haired guy would be sporting a watermelon belly and rolling his eyes.

"Enough of this nonsense. The illusion test is passed. I will revise the test content."

Unaware of Uchiha Gin's dark and sordid thoughts, Senju Hisa shook her head and turned her gaze to the unconscious Nawaki's face.
"Women are just too much trouble."

Muttering a disgruntled sigh, Uchiha Gin adopted a nonchalant expression, awaiting the details of Senju Hisami's test.

This curly-haired guy gave her a heads-up: with physical techniques and illusions out of the question, that left her with only escape techniques as an option.

Recalling Nawaki's meager skill set and his rather crude chakra manipulation techniques, Senju Hishi suddenly had the answer.

"No, it's an A-rank ninjutsu."

To discourage Uchiha Gin from trying, Senju Hisami deliberately increased the difficulty.

"what?"

Uchiha Gin blinked, completely bewildered. What kind of test was this?

"If you can teach Nawaki to master an A-rank ninjutsu within a week, I will consider him to have passed the test."

"Isn't your test too vague?"

In most cases, ninjutsu ranking is not the sole criterion for determining its destructive power; rather, it represents the level of difficulty in mastering it.
Techniques like the Palm Healing Technique, the Telescope Technique, and the future seventh generation's signature technique—the Harem Technique.

These non-lethal support-type ninjutsu were also classified as A-rank.

Thinking of this, Uchiha Gin thoughtfully stroked his chin.
Nawaki has a huge amount of chakra, why don't we teach him the Multiple Shadow Clone Technique?
Simple and quick.

"You think it's simple?"

"It's alright, it's not too difficult~"

Having already made up his mind, Uchiha Gin nodded upon hearing this.

"Hmph! I knew you'd say that. My test is not just about mastering A-rank ninjutsu."

Looking at the confident Uchiha Gin, Senju Hisami snorted coldly.
How could she not know that this curly-haired old man was cunning and calculating? Having lived this long, even a dog would have some knowledge stored up inside. Teaching Nawaki ordinary A-rank ninjutsu was a piece of cake for him.

"Are there any additional conditions?"

Uchiha Gin frowned; he knew this white-haired guy wouldn't be so kind.

“That’s right. The ninjutsu that Nawaki uses must be a completely new ninjutsu that I have never seen before, and it must be an offensive type that can cause damage.”

Seeing Uchiha Gin's increasingly troubled expression, Senju Hisami tapped her fingers lightly, a rare smile appearing on her face.
"As for the ninjutsu level, you don't need to worry about it. I will make my own judgment."

"You're so despicable!"

This test is no easy feat; Senju Hisashi's title as a ninjutsu master is far more prestigious than Sarutobi Hiruzen's title of ninjutsu professor.

She can use almost any A-rank ninjutsu available on the market, if not master it.

As for those closely guarded secret ninjutsu, she had some knowledge of them, though not all of them.
"So, if you want to give up, you can surrender now."

Seeing the Uchiha clan member's discomfiture, Senju Hisajin chuckled, picked up the half-empty caramel macchiato, and began to savor it with relish.
"You've really stumped me."

Uchiha Gin nodded calmly. The difficulty lay in the sheer number of choices he had, which caused him to suffer from decision paralysis for a moment.
"If you feel it's too difficult, just admit defeat. You don't need to blame yourself for losing to someone who is proficient in all ninjutsu."

Unaware of this, Senju Hisana was still smugly looking down at Uchiha Gin, who was deep in thought, with the air of a victor.
Just then, intermittent whispers came from the side.
"Daddy, Daddy's gone! Next time, I'm definitely going to win!"

Turning his head to glance at Nawaki, who was still unconscious, and listening to the other's delirious ramblings, Uchiha Gin gently shook his head. A surprising fighting spirit flashed in his usually lifeless eyes.

"That being said, I still want to give it a try. Even Nawaki hasn't given up, so how can I, as his instructor, surrender?"

"Hehe, commendable courage. In that case, how about we add a prize to make this test even more challenging?"

Senju Hisa looked at Uchiha Gin with some surprise. After a brief moment of distraction, she curled her lip in disdain and made a suggestion that was very advantageous to her.
"The prize?"

"Yes, if you pass the test, I will not only stop interfering with Rope Tree's cultivation of that disgusting bloodline, but I will also give you the one million taels you just mentioned."

"make a deal!"

"Don't rush, we haven't talked about the punishment for failure yet."

Seeing Uchiha Gin's impatient expression, Senju Hisami raised an eyebrow, looking smug.

"If you fail, besides Rope Tree no longer cultivating that bloodline limit, you must also agree to one condition of mine."

"make a deal!"

"Uh, you didn't even ask what the conditions were?"

Senju Hisa's expression froze. Shouldn't she be asking her about the terms at a time like this?

"No need."

Unless this white-haired guy is inhuman and insists on calling A something else, he absolutely won't lose.
But just to be on the safe side, it's best to have a few authoritative notaries present, in case this white-haired guy denies everything.

"Good, remember this arrogant look you have now."

When you lose, your curly hair won't even have time to cry.
Senju Hisami glared fiercely at the nonchalant Uchiha Gin, and said through gritted teeth,
If it weren't for the fact that it was in Banza's presence, she would have already pulled out a pen and written a tally mark on that bastard's thigh.

Thinking of Itama, a gentle light flashed in Senju Hisami's eyes, and a warm smile appeared on her lips.

The conditions she wanted to make weren't actually demanding; she simply wanted Uchiha Gin to give her sister a legitimate status.

"Ugh~ Why are you suddenly laughing so disgustingly?"

"Mind your own business! Hurry up and wake up Rope Tree. The test time starts today."

Seeing Senju Hisama's face change at a speed comparable to that of a peak Kawajima, Uchiha Gin showed no sign of anxiety. Instead, he thoughtfully looked at the medical gloves on the table.

He always felt guilty about accepting that million, and felt he had to resort to violence to resolve it.

"Oh well, what can I do when my medical ethics are so noble?"

With a sigh, he picked up his gloves and put them on again. Under Senju Hisama's questioning gaze, he gently pulled down the pants of the unconscious Nawaki.

"Wait! What are you going to do?"

Uchiha Gin stared solemnly at Senju Hisami, whose face was filled with astonishment. A scalpel, seemingly appearing out of nowhere, flashed across his face.

"What to do? Do what a doctor should do."

A barely perceptible cutting sound rang out, and Rope Tree's brow furrowed sharply. But because the knife was so fast, the wound didn't even have time to react; the pain had already subsided before it even struck.
"I didn't expect you to have such good professional ethics."

Looking at the Kunpi lying on the ground, Senju Hisajin's face was filled with complex emotions.

"How about a painless circumcision? We're honest people, we can't let you waste your money, right?"

As he spoke, he raised his knife again, this time targeting the unconscious Fugaku on the other side. The scalpel, sharp enough to cut without drawing blood, gleamed coldly, making Senju Hisa's heart tremble.

"If we're brothers, we'll cut down the skin of the dragon together." (End of Chapter)
