Naruto: The Medical Ninja

Chapter 268: Chapter 265: Copy of the Instincts

A month had passed since the beginning of the [BodyGPT] project. While Hokage Hiruzen Sarutobi had returned to the Leaf Village after a brief respite, Dan Hamura and Yuki Sarutobi had remained in the Land of Rivers, dedicating their considerable expertise to help Ryu Hamura with this groundbreaking Fuinjutsu seal.

Every day, Ryu, Dan Hamura, Tsunade Senju, Yuki Sarutobi, and occasionally Shizune met in Ryu’s [Mind Palace] for several hours to meticulously work on the [BodyGPT], combining their expertise in Fuinjutsu and medical ninjutsu.

The seal, when rendered virtually within the [Mind Palace], was a breathtaking sight when zoomed out to a full view. It appeared as an incredibly complex, full-body tattoo, its intricate lines and symbols flowing across the virtual body of Souji, pulsating with a faint, internal glow.

Every detail, every function, was woven into its design with astonishing precision, and there was room for more growth unknown to everyone but Ryu.

Ryu felt extremely satisfied with the design, and the team was highly impressed by its innovation.

”Another one of my secret weapons is now complete.” Ryu said, surprising everyone. They had almost forgotten Ryu mentioned the same earlier.

”Weapon? What do you mean by that?” Yuki asked. ”Didn’t you say it is a mobility seal?”

Ryu smiled and said, ”Yes, but I also said it could be a secret jutsu of our clan. Like a knife, which can be used in the kitchen to cut vegetables and also as a weapon. This seal is the same. It all depends on how I use it.”

Others looked at Ryu with all the obvious questions in their eyes, wondering what other secrets he may be hiding up his sleeve.

Ryu finally answered their unspoken questions, ”This seal can be integrated by another seal as a secondary function of it. That could be utility seals like [Storage Seal] to store a number of fuinjutsu cards on my body or many defensive seals like [ReflexGuard].”

”Imagine the fighting style with an impact-absorbing barrier on the body itself or impact-generating... Ohh boy.... I have so many ideas with this seal.”

Ryu’s explanation left the group in awe, realising the versatility and power of his seal. They now understood that his abilities went beyond what they had initially assumed, making him a formidable opponent in any situation.

Tsunade’s eyes widened at his casual declaration. ”If that’s truly the case,” she mused, a new idea sparking in her mind, ”then you could permanently place your barrier and defensive seals, always active, on your body. Like earlier, but in a more permanent manner.”

Ryu giggled with a mischievous glint in his eyes. ”Not just that, Auntie. I can now write it on my ninjas and make them living weapons. This [BodyGPT] will act as a slotting mechanism for me to grant power to others.”

His words hung in the air, leaving the team in stunned silence, processing the implications of his statement. The idea that Ryu could, in seconds, bestow complex abilities upon his recruits, turning them into formidable assets, was almost unbelievable.

”Then you weren’t wrong in claiming this seal as our secret weapon,” Dan finally stated, his voice filled with a newfound reverence for Ryu’s ingenuity.

Ryu’s smile widened, but then he shook his head slightly, surprising them all once more. ”Right, but I didn’t classify this seal as a weapon due to that capability alone.”

”What more is there to this seal?” Yuki asked, her curiosity piqued, unable to fathom what else could make it more profound.

Ryu explained, his voice taking on a more serious tone. ”With its export feature, I can take a post-training [BodyGPT] out of a user’s body and then grant or ’bless’ it to others.”

Ryu paused, letting the concept sink in. ”Think of it as a blueprint of how a body should move. It’s an ingrained battle sense, a set of instincts that normally comes only through years of rigorous training. If I place this seal on myself and train, let’s suppose, [Academy-style Taijutsu] with it, then all the body movements and instincts related to that taijutsu will be embedded within the seal itself.”

As he spoke, Ryu’s doppelganger materialised within the [Mind Palace], the [BodyGPT] glowing faintly on its body. The doppelganger moved through a series of precise, fundamental taijutsu katas—punches, kicks, blocks—each movement executed with flawless form and economy of motion. As it moved, shimmering lines of chakra, almost like data streams, visibly flowed from its limbs into the intricate patterns of the [BodyGPT] seal, illustrating the recording process.

”The [BodyGPT] will record and always retain that data,” Ryu continued, his voice calm, ”So, when I copy that seal onto, let’s just say, a five-year-old, their body will immediately be able to move as if they had trained for years.”

”We could train a whole squad in advanced taijutsu in months, not years!” she exclaimed, her eyes blazing with strategic insight. Tsunade was incredulous, immediately envisioning the seal’s potential combined with [Senju-style Taijutsu] training, a vision of an instantly formidable fighting force.

”Indeed,” Ryu confirmed, ”I know what you are thinking. But there will be some limits, of course. Special jutsus. Where the bar for learning is high, like the [Strong Fist Taijutsu], [Senju-style Taijutsu], or the [Eight Gates]... they are all still out of reach for this. Nevertheless, I believe that people without any fighting sense can be ’blessed’ using this seal after it is properly trained. First, we need to train it for basic body movements. After that comes training for complex movements, like simple fighting stances and throwing sense, then an E-rank academy taijutsu and then Genin-level D and C level taijutsu.”

They were still thinking about what Ryu said when he dropped another bomb. ”We can create multiple versions of this seal, each specialised in different kinds and levels of taijutsu, to optimise the learning and training process. Teaching one seal every kind of taijutsu would not be an optimised way. I need to train the seal using someone who has no prior knowledge and is starting from zero, so a fully functional blessing seal from me for combat purposes is years away.”

Tsunade, as a ninja and one of the Legendary Sannin, fully grasped the profound implication of such a Fuinjutsu. Even if it couldn’t instantly bestow A-rank or S-rank taijutsu, the ability to grant basic taijutsu in seconds and other minor Fuinjutsu skills permanently was revolutionary. It could transform an entire army, creating competent fighters in the shortest time possible.

”With this seal, training your private ninja force will be incredibly easy and fast!” Yuki added.

Ryu nodded. ”And after a few years of training a person with the help of a fully trained version of this seal, we can even remove it. But even after removing it the ingrained instincts and muscle memory will remain, allowing them to continue to fight like they did before when they had this seal.”

The implications of this new Fuinjutsu seal were immense, potentially changing the landscape of warfare.

”Imagine the possibilities for expanding our forces and the Hamura Clan,” Ryu mused, his mind already racing with potential applications for the new seal. The seal truly had the power to revolutionise their entire approach to warfare.

They all stared, trying to picture it. Shizune, in particular, grappled with a significant ethical dilemma regarding the use of Fuinjutsu, even for healing purposes.

”Lady Tsunade,” Shizune began, her voice hesitant, ”I’ve been thinking about [BodyGPT]... doesn’t intervening with the brain’s essence, even for healing, cross a line? Does it truly respect a ninja’s natural development?”

Ryu, with a composed expression, locked eyes with her. ”Shizune-san, [BodyGPT] is crafted to impact motor functions and deep-rooted instincts. It does not interfere with higher consciousness or personal volition. Consider it akin to an advanced muscle memory implant, not a technique that alters the mind.”

Tsunade nodded, understanding the nuance in Ryu’s explanation. ”He’s right, Shizune. We’re not tampering with who a person is but rather optimising how their body moves and learns. Its application is well within ethical bounds for its intended purpose.”

Reassured by their explanations, Shizune visibly relaxed. Now, after weeks of painstaking effort, the seal was finally complete.

There was silence for some seconds, then Dan chuckled, shaking his head in amused disbelief. ”Where do you get such ideas, grandson?”

His mind momentarily transported him back in time, recalling the fierce brilliance of Mito Uzumaki, known for her intricate sealing arrays, and the calculating genius of Tobirama Senju, renowned for his innovative applications of space-time ninjutsu.

Both masters together pushed the boundaries of Fuinjutsu and created the most forbidden space-time ninjutsus in the world: the [Shadow Clone-Jutsu], the [Flying Thunder God-Jutsu] and finally the [Impure World Resurrection- Jutsu] .

Yet, even their combined ingenuity seemed to pale in comparison to the sheer audacity and scope of Ryu’s vision.

”Ryu, you truly are a unique spark,” Dan said in his thoughts, recognising boundless and limitless innovation in Ryu.
