Naruto: Wood-Wood Fruit

After dinner.

It wasn't just Shizune who followed Kiyoshi back to his room. Tsunade and Karin, full of curiosity, also came along.

Seeing Shizune sitting there cross-legged, a bit nervous, Kiyoshi smiled and said.

"Shizune-senpai, there's no need to be nervous. I've already tried this on other ninjas, so theoretically, it should work."

Thanks to Kiyoshi's guidance, Shizune had progressed far beyond her original potential. In these two years, with constant effort, her chakra control had significantly improved. 

While she still hadn't reached the level required to fully master the Yin Seal, she could manage some of Tsunade's powerful techniques.

"Wait, Kiyoshi." Shizune raised her hand, a bit hesitant, and voiced her concern. "Even if you help me form the Yin Seal, my chakra control still isn't enough to fully master it."

Kiyoshi nodded, smiling as he explained, "For most people, this approach wouldn't make much sense. Once my spirit leaves, they might not even be able to tap into the sealed chakra.

 But you're different. Your chakra control has come a long way these past two years, and your medical ninjutsu is quite strong now."

"If you take this opportunity to truly experience the process of the Yin Seal and the Strength of a Hundred, repeating it over time, your body will gradually develop muscle memory for it," he continued.

Tsunade, rubbing her chin, nodded in agreement. "With this foundation, if you keep up the effort, you might actually master these two techniques."

Tsunade could clearly see how hard Shizune had been working. However, talent, ability, and aptitude often felt like barriers that hard work alone couldn't overcome.

Luck and opportunity played crucial roles. Kiyoshi, it seemed, was that luck Shizune needed. Maybe this time, success was possible.

"If it doesn't work the first time, we'll try again," Kiyoshi said with a warm smile. "Even if it takes ten, or even a hundred times, I'm sure you can do it over time."

Shizune had silently supported him these past two years, helping him in every way possible, never once expecting anything in return. 

This was the least he could do to repay her kindness. For anyone else, he wouldn't have been this patient.

"Kiyoshi." Shizune gazed at him, moved. A warm feeling welled up within her, touched by his encouragement. "Thank you."

"Do we really need such words between us?" Kiyoshi chuckled. "You've helped me so much over these years."

Shizune's eyes sparkled, and she nodded earnestly, a soft smile on her face. The Yin Seal and the Strength of a Hundred complemented each other. 

For someone with Tsunade's training and solid medical skills, mastering these two techniques was almost like a ticket to eternal youth.

Even someone as reserved and modest as Shizune couldn't help but feel a bit excited. After all, what woman wouldn't want to stay young like Tsunade?

"Good luck, Shizune-nee." Karin cheered, clenching her fists in sincere encouragement. 

Over the past two years, Shizune had been like a real sister to her, always there, caring for her in every detail. 

Even Tsunade and Kiyoshi hadn't been as thoughtful and attentive. 

To Karin, who had lost her mother, Shizune had become one of the people who cared about her the most. 

She truly hoped Shizune would succeed in mastering the Yin Seal and the Strength of a Hundred.

"Tsunade-nee, Karin, please wait outside," Kiyoshi said with a smile. "With me here, there won't be any problems."

"Alright, but be careful." Tsunade nodded. She knew that practicing the Yin Seal and the Strength of a Hundred required absolute silence. 

Confident in Kiyoshi's abilities, she trusted him to handle the process safely, even if they didn't achieve instant success. With that, she led Karin out of the room.

"Alright then, let's begin." Kiyoshi sat cross-legged, forming hand seals calmly and steadily. In an instant, his translucent spirit detached from his body and entered Shizune's.

"Eh? Kiyoshi?" Shizune felt a moment of dizziness and then found herself in her own mental realm. 

She gazed at Kiyoshi standing before her in shock. "Is this the Spirit Transformation Jutsu you learned from Uncle? It's incredible."

"To be precise, it's a Jutsu your uncle learned, not something he invented," Kiyoshi clarified with a smile. "It was actually developed by the Second Hokage."

Shizune nodded with a smile, looking at him. "Alright… What should I do now?"

"Just relax, let go of control over your body, and don't resist in any way," Kiyoshi instructed. 

"Focus entirely on the flow of chakra and every little change in your body. Don't miss a single detail."

"Leave everything else to me. Next, I'll be fully controlling your body."

"Got it."

With Shizune's full cooperation, Kiyoshi smoothly took over her body, unlike his previous method with the ninja from Yugakure, where he had to forcibly suppress the target's consciousness.

The next moment, "Shizune" opened her eyes.

"She" stretched, standing up and moving around a bit. Swinging her arms, kicking her legs, bending her waist…

Adjusting quickly to this somewhat unfamiliar body.

"Huh? Kiyoshi, you're."

Shizune, still within her mental space, blushed as she saw Kiyoshi put her body into a split.

It was a strange feeling. Every movement he made, she could feel as if she were doing it herself. 

Yet at the same time, it was as if her own body had no secrets from him, making her feel a bit embarrassed.

"Ahem, I was just checking your body's flexibility—it's essential for this." 

Kiyoshi coughed, slightly awkward, as he summoned a blue chakra ball in his palm and began manipulating Shizune's chakra to form a Rasengan. 

Testing the control he had over her body, he remarked, "Alright, let's begin."

He had to admit, his senpai was incredibly flexible—naturally gifted for this sort of thing. 

She just dressed a bit too modestly and reservedly, turning herself from the student of one of the Sannin into someone easy to overlook.

If she dressed up a bit, her charm would definitely increase by at least twenty points.

It looked like he'd need to guide her in the right direction in the future.

As for physical improvements.

It seemed he could use this opportunity to make subtle adjustments to her body with his precise chakra control, helping her improve over time. 

Like water wearing down stone, slowly but surely. All natural, no artificial additives.
