Knock, knock, knock.
Not long after Kakuzu and the others left, a knock sounded on the door. Kageyama Kogetsu, who was handling administrative affairs, said "Come in," and a familiar figure strode in.
This person had long, light blonde hair tied into a large ponytail, a blue-purple mark of the Strength of a Hundred Seal on her forehead, thin and short light blonde eyebrows, bright brown eyes, light red lips, and red nails.
Her skin was fair and tender, her figure voluptuous and imposing. She wore a tea-green haori with black trim over a loose, sleeveless, kimono-style top, a black sash around her waist, and dark blue capri pants. She looked heroic, neat, and capable.
"Senior Tsunade is back. Welcome, welcome," Kageyama Kogetsu looked up and smiled.
"Hey, hey, why isn't my name on the expedition list?" Tsunade asked with a displeased expression.
"Ah, isn't your illness not cured yet?"
"Considering that I and other ninja can summon Katsuyu, I didn't want to trouble you. Just stay and guard Konoha," Kageyama Kogetsu explained calmly.
Hearing this, Tsunade looked disappointed. Had she, one of the legendary Sannin, become useless?
No, she was not useless!
"Even if what you say makes sense, with me, we can summon even more of Katsuyu."
"Besides, my rich medical experience can also guide the medical corps, allowing injured ninja to recover faster."
"I want to go to the battlefield."
"Jiraiya, Orochimaru, Sensei, and the younger generation are all going. What's the point of me staying in Konoha?" Tsunade said firmly.
"Your two disciples going to the battlefield is equivalent to you going."
"Nonsense! I don't care, I want to go to the battlefield. Otherwise, I won't leave, and I'll go to your house and pester you!"
Tsunade walked to the desk, leaned on it with both hands, and "threatened viciously." But she didn't look intimidating at all; instead, her assets looked even more imposing.
As Kageyama Kogetsu's prestige grew, his power increased, and the strength he displayed became more terrifying, acting shamelessly was undoubtedly a wise move for those close to him.
It wouldn't hurt their relationship, and the probability of achieving the goal was not low.
Kageyama Kogetsu: "..."
Women were sometimes harder to deal with than children or old people. Why was she acting shamelessly again?
Could it be menopause?
Tsunade treated him well enough. With no shortage of combat power and medical resources, there was no need for her to risk her life on the battlefield.
Although he had the ability to revive people, he didn't want to abuse it, or there would be endless trouble.
If only he could cure Tsunade's hemophobia. But it was a psychological problem, and medical ninjutsu wouldn't work.
A heart disease requires heart medicine. He wasn't Naruto... hey... wait a minute, he seemed to have heart medicine!
That heart medicine was just sitting idle anyway. Using it would also repay the favor of Tsunade teaching him Monstrous Strength and medical ninjutsu back then.
"Senior Tsunade, I have a method that might cure your hemophobia. Do you want to try it?" Kageyama Kogetsu asked seriously.
Tsunade was stunned, then excited.
As the medical saint of the ninja world, she was afraid of blood. Although she knew it was a war trauma left by Dan's death, it was still a humiliation!
Kogetsu was so strong; his method might really work!
"What method?" Tsunade asked eagerly, her eyes full of anticipation.
"You'll know this afternoon. I need to prepare."
"Tch, so mysterious." Tsunade pouted. "I'll come find you this afternoon. I'm going for a drink."
"It's broad daylight. Don't drink too much. Come early this afternoon."
"I know."
...
At noon, after returning home and having lunch, Kageyama Kogetsu called Sasuke aside. With a flip of his palm, a glass jar containing an eye appeared in his hand.
"Father, who do you want to use Big Brother Shisui's Mangekyō Sharingan against?"
Sasuke was first surprised, then calm, as if it didn't matter who it was used against.
Back then, after defeating Itachi and retrieving Shisui's Mangekyō Sharingan, Sasuke had loyally handed it over to Kageyama Kogetsu.
Kageyama Kogetsu didn't accept it immediately but let Sasuke familiarize himself with the "Kotoamatsukami" technique before taking it, just in case.
"Not against anyone, but to treat your Aunt Tsunade's illness."
Although given Tsunade's age, it would be more appropriate for Sasuke to call her Grandma Tsunade, Tsunade, who always maintained her youth, wouldn't want to hear that.
"Your Aunt Tsunade suffers from a war trauma called hemophobia because she was helpless as her lover died before her eyes."
"As the name suggests, it's a fear of blood. Once she sees blood, your Aunt Tsunade's mind goes blank with fear, and she completely loses her combat ability."
"So I plan to use Kotoamatsukami to modify your Aunt Tsunade's will. It should cure her illness," Kageyama Kogetsu explained with a smile.
"I see." Sasuke suddenly realized, then said excitedly, "What a genius idea!"
"Kotoamatsukami can actually be used to cure illnesses and save people..."
Kageyama Kogetsu laughed heartily. "Haha, ninjutsu is like a ninja tool. Used for good, it is good; used for evil, it is evil."
"Prepare yourself. Come find me at the Hokage Tower this afternoon."
"Yes."
Sasuke took the glass jar, bowed, and turned to perform the eye transplant surgery on himself.
With two godmothers, Xiangmei and Nonō, who were skilled in medical ninjutsu at home, and Sasuke being eager to learn, although his medical ninjutsu wasn't brilliant, changing an eye for himself was no problem.
However, with a mortal body, it was impossible to achieve the plug-and-play capability of Six Paths Madara Uchiha.
After changing his eye, Sasuke lay on a chair in the garden, pondering how to cast the jutsu...
The cooldown time for Kotoamatsukami was too long. Even with methods to shorten the cooldown, it was still long.
Father entrusted this matter to me. I can't make any mistakes. I must succeed in one go!
Forcing Aunt Tsunade not to fear blood seemed insufficient; it would treat the symptoms but not the root cause.
To treat both the symptoms and the root cause, the painful memory had to be eliminated. Without the source of the psychological shadow, the psychological illness would naturally be cured.
Mm... let's do that!
Speaking of which, Aunt Tsunade was quite pitiful. She had lived in a psychological shadow for decades. Besides Shizune's constant companionship, she didn't even have a boyfriend and had been single for decades.
Unless something unexpected happened, the direct bloodline of the Senju clan would end with Aunt Tsunade.
So miserable. In her old age, she should enjoy some happiness.
How to enjoy happiness?
Of course, by following Father. Mother and the godmothers were all very happy, with smiles on their faces every day.
Besides, her youth would be maintained for a long time, and there was the Living Corpse Reincarnation technique for longevity.
Following Father, Aunt Tsunade would truly hit the jackpot.
After this move, the Uchiha clan would owe the Senju clan nothing.
Although he was acting on his own initiative, Father shouldn't blame him after finding out. At most, he would scold him superficially.
He had a little selfishness, but more of it was filial piety!
His filial piety was greater than Naruto's. He was Father's most sensible and capable son!
Having made up his mind, Sasuke got up and left home, heading to the Hokage's office early to learn how Father handled administrative affairs.
As long as they defeated the Masked Man and his group, he would shoulder more responsibilities in the future. He had to improve.
That guy Naruto was reliable in some things, but not in others.
Around two in the afternoon, Tsunade, smelling faintly of alcohol, arrived at the Hokage's office with a mix of excitement and anxiety.
Seeing Sasuke there too, Tsunade was a little surprised. She greeted him openly and then couldn't wait to ask...
