The training for the Rasengan had been completed two years ago. By now, he could even add various elemental nature transformations to it.
In fact, he could achieve multi-elemental nature changes, though for the moment, he maxed out at three types at once.
Showing it to Tsunade now wasn't about teaching her, of course. It was about using the Rasengan to "inspire" her.
"Well, consider it a ninjutsu I developed myself. The name is Rasen... ahem, Three Points Return to Origin."
Although it technically counted as plagiarism, who asked him to be born earlier?
The current Minato Namikaze should have already been born; maybe Gisei was even the one who delivered him.
Thinking of this, Gisei instantly felt his image become much taller and grander.
As for "Three Points Return to Origin," Gisei felt the name "Rasengan" was just too weak. It sounded like a ninjutsu used by some small-fry extra, definitely not fitting for a protagonist like him.
Anyway, since he was the one using it now, it was his ninjutsu, and no one could change its name.
Imagining a future where Naruto shouts, "Eat my Three Points Return to Origin!" Gisei revealed a fatherly smile.
"Three Points Return to Origin... what a weird name. What do you mean by showing me this?"
Tsunade thought Gisei just wanted to show off, though she had to admit—the kid was amazing. Looking solely at talent in jutsu, even Orochimaru was far inferior.
Just sensing the chakra fluctuations of this "Three Points Return to Origin," she could tell it was at least an A-rank ninjutsu.
Gisei took a deep breath and said expressionlessly, "You really don't understand a man's romance."
Shaking his head, he smashed the Rasengan into the ground.
A perfectly circular hole appeared, exactly the same as the one under his foot earlier.
Tsunade looked left and right, then was instantly dumbfounded.
"Releasing an A-rank ninjutsu with your foot... are you even human?"
"You don't think I can do it just like you, do you? No, no, I absolutely can't do that."
Gisei crossed his arms over his chest with a look of arrogance.
Releasing the Rasengan with his foot wasn't difficult for him; it just wasn't as convenient as using his hands.
"You're overthinking it. Even if you wanted to learn this kind of ninjutsu, I wouldn't teach you unless you pay extra."
Tsunade: "Can we not talk about money?"
Gisei: "No."
Tsunade rolled her eyes. "I didn't plan to learn it. Does this ninjutsu have anything to do with improving my speed?"
Gisei nodded. "You saw it just now; this ninjutsu relies on the rotation of chakra to unleash its power."
"My point is, when you burst out with chakra, make the chakra at the soles of your feet form a similar rotating posture. This will greatly improve your speed."
After finishing his explanation, Gisei waved his hand at her. "Well, that's it. Good luck!"
After walking a few steps, he turned back. "Don't forget to bring the money tomorrow. I hope we have another opportunity to do business next time."
After Gisei completely disappeared, Tsunade looked at the two round holes on the training ground and fell into silence.
The soles of the feet are the part of the body furthest from the brain. Controlling chakra there is already difficult, and to form a rotating posture on top of that...
Tsunade felt like she couldn't do it, but then she remembered Gisei's extreme speed just now.
Taking a deep breath, she began her training.
She was not a woman who admitted defeat easily.
After sending Tsunade away, Gisei spent a boring day at the hospital.
The next day, however, he went to work with a face full of joy.
Another large sum of money came in today, and his assets finally broke through to nine figures.
It wasn't easy. Thinking about the money that had passed through his hands these past few years, Gisei's teeth ached from anger.
Tens of millions came in every year, and before they could even get warm, they had to be sent out. Various expenses weighed on him, almost making him breathless.
The fifty million he got from Tsunade had been given to Sadahisa to purchase instruments, so there wasn't much left of that. The current money was all earned from his hard work performing surgeries—he was almost sick of doing them.
Tsunade was a good woman; aside from being broad-minded, she didn't even blink when spending money.
Truly worthy of being the legendary "Fat Sheep." She was simply his savior.
In his office, the two met again.
Upon seeing him, Tsunade took out a black leather suitcase and extended it to him.
Gisei took a scroll from his chest pocket and placed it in her hand, whistling. "Pleasure doing business."
Tsunade felt angry just looking at his expression. Of course, she knew she had been ripped off, but who asked her to need this thing so badly?
Unable to bring herself to smile after being scammed, she could only glare at him fiercely before turning and leaving.
The following days were rather boring.
Tsunade would show her face at the hospital every day, and then vanish.
Gisei certainly knew what she was doing and couldn't be bothered to fuss about it. After all, he had gotten so much money from her; gossiping about it would be undignified.
The Medical Unit could function normally without Tsunade; it was just a little more tiring.
But that had nothing to do with Gisei. He sat in his office playing with bugs every day. If there were problems that really couldn't be solved, members of the Medical Unit would come to call him.
Life was leisurely and extremely comfortable.
As time passed, Gisei found that this life was actually quite nice.
Ever since Shuichi Takemoto guessed his thoughts, he hadn't let anyone disturb him, and even those ninja clans had become much more well-behaved.
He didn't know if this was a good thing or a bad thing.
Even if Takemoto was dying, he was definitely not a simple person. Moreover, he was quite obsessed with his clan, so there was no reason for him to just give up like this.
But since he couldn't see through that old fox, he could only deal with things as they came.
As for the village, it remained peaceful and harmonious.
Occasionally, he would go to report the Medical Unit's work to the Third Hokage. Every time the Third saw him, he would just ask a few routine questions before letting him leave.
As for Danzo, it was as if he had completely disappeared from Konoha. Previously, one could occasionally see him on the streets, but now there was almost no trace of him.
Actually, Gisei was quite curious about what Danzo was doing now.
If nothing unexpected happened, Danzo should have already set his sights on the Sharingan.
After all, the only good eyes one could get in Konoha were the Sharingan; there was definitely no hope for the Byakugan.
Originally, Gisei wanted to fish in troubled waters to see if he could get a few Sharingan to study, but after thinking about it carefully, he gave up.
If it were the Mangekyo, Gisei would definitely wade into the muddy waters, but three-tomoe eyes were a bit unsatisfactory. Even if he studied them, there wouldn't be any major results, so why provoke a mess?
Moreover, Mei had given him something good recently, which had attracted all his attention.
This "good thing" was a notebook.
Yukihito Shiraishi, his grandfather, had written the notebook by hand.
It mostly contained events his grandfather had personally experienced, as well as many insights into ninjutsu training.
Gisei had been studying this notebook recently, almost to the point of obsession.
Because the things recorded inside were just too interesting.
