Naruto: Reshaping the Shinobi World with Sasori

Chapter 152 Yubi's Art, Life Medicine!

Yubi opened the Uchiha's skull.

Various resections and surgical experiments were performed on different regions of its brainstem.

This was used to observe the effects on the Sharingan.

His Reversal Technique can heal any injury, so he's not afraid that the Uchiha's experimental subjects will suddenly die.

If he wanted to, even if the Uchiha's brain tissue was shattered into a pile of mud, as long as his vital signs did not disappear immediately, he could restore his brain in a short time.

"As expected—this kind of eye technique primarily relies on the mental power of the brain—"

"Emotional stimulation doesn't seem to be very effective; it can't upgrade a two-tomoe Sharingan to a three-tomoe Sharingan. In other words, it's very difficult to create a Sharingan through artificial intervention—I'm a bit disappointed—"

During this time, Yubi performed brain surgery on the Uchiha, turning him into a living being in a vegetative state, only able to receive some simple commands.

However, these instructions allow this Uchiha to maximize the emotional stimulation he experiences after eliminating all distracting thoughts.

He had already used his surgical skills to activate the brain's magnetic field to its maximum value, yet—even so, the man's two tomoe remained unchanged.

"Unfortunately, the current level of technology in this world is relatively limited, and many external medical tools and instruments cannot be used. Otherwise, the surgery could be more precise, and the results that I can achieve myself would be even better." After a while, Yubi sighed and restored the Uchiha's head.

He took a step back and met the gaze of the Uchiha man.

At this moment, the latter's two eyes were as follows: one eyeball was red with two tomoe, while the other was a normal black and white eyeball, seemingly not yet opened.

The eyeball that wasn't opened was regrown by Yubi after he removed one of Yubi's Sharingan eyes using a reversal technique.

Yubi's idea was to use the Uchiha experimental subjects, combined with his Reversal Technique, to achieve an unlimited production of Sharingan 4.

O

But clearly, the final result was a failure.

The extracted Sharingan with two tomoe has been bottled and stored away.

Yubi is certain that this new eyeball, although "original," cannot be opened yet.

"The condition for the awakening of the eye—that was removed—was achieved through years of chakra infusion and alteration." This isn't simply a matter of the brain—the brain is merely a switch, or rather, a limiter.

Yubi put down his tools, stroked his chin, and pondered.

In other words, these newly grown eyes are more like the original body's eyes when it was an infant—it takes time for the Sharingan to develop.

The exact timeframe is currently unknown.

It's like creating a new game account.

But in essence, there are still conditions for "becoming a Sharingan".

It just can't be turned into a double tomoe immediately.

"Alright, you can go to the side now."

Yubi waved to the stiff-faced Uchiha.

Upon hearing this, the latter, like a robot, walked a few meters away and stood motionless.

Yubi performed some brain tissue removal surgery on him. To put it simply, this Uchiha has now become a tool that only accepts his instructions. He no longer has a strong sense of his own, and only his basic thinking ability is guaranteed to ensure that his actions are not interfered with.

Industry specializing in surgery.

Sasori's puppetry technique allows ninjas to become his art objects after death—while using the puppet core, the deceased can still use some of their life techniques after becoming a puppet.

As a doctor, Yubi could also achieve similar conditions.

The art of scorpion is more complex and more perfect than that of scorpion.

It is true life medicine.

It involves physically intervening in the human brain to turn it into an obedient puppet—the physical erasure of consciousness.

If it weren't for the limitations of the current technological level in the world, the achievements he could have made would have been even more terrifying.

This is what makes the Black Man's abilities so abnormal.

Of course, performing this kind of surgery is not that simple.

The target needs to be under absolute control—otherwise, no one would be willing to have their head opened at will.

Moreover, Yubi didn't have enough understanding of the power system of this world before, and he was unable to integrate and experiment with some theories and his medical knowledge. Only after he had a certain understanding of the principles of chakra and ninjutsu did he have the basis to start.

At least—know how to do it.

Furthermore, although they are also human beings, the ninjas of this world are not the same people that Yubi knew in her previous life.

Back when he was interning at the Sunagakure Hospital, Yubi discovered that the ninjas of this world—in terms of life alone—were a completely different kind of being from what he considered "humans."

"Because of the unique power system"—primarily the chakra system—the ninja's cell walls and cell nuclei underwent a qualitative change.

That's right, people in this world do have cell walls—

It can be understood that the ninjas in this world are simply "retaining" human form.

This also allows the flesh and blood of ninjas to evolve from "more angles" and achieve incredible and magical phenomena.

For example, the chakra in a typical ninja's body is like bulk cement; you only bring out as much as you need.

Orochimaru's Cursed Seal Technique is equivalent to installing an expansion card into an individual's chakra system, along with an independent CPU that can be implanted into the original system. This allows him to rewrite cellular genes, increasing cell division speed by more than 300%.

The normal cell wall replacement cycle is usually 7 days, and it may take longer depending on the level of training and physical strength.

This undoubtedly leads to a comprehensive improvement in various bodily attributes, including the speed of recovery and self-healing.

This seal also allows one to achieve precise control over chakra, enabling the flow of chakra in every cell of the body and allowing muscle fibers to complete energy conversion at an ultra-high speed.

The speed at which chakra was processed reached an astonishing level.

After being "modified by the cursed seal", although it is still human flesh and blood, the "material" of its body, that is, its strength, has far exceeded that of metal.

However, from Yubi's perspective as a doctor, the side effects of this cursed seal are undoubtedly system overload, physical overload, cellular abnormalities, and the possibility of cancer.

If cell division goes out of control, the ultimate consequence will be the explosion of the physical body.

The reason for giving this example is to say that if it were a human being as he knew them in his previous life, once the curse mark was placed on them, it would be 100% failure, with absolutely no chance of success.

However, in this world, given the innate life strength of ninjas, especially at the cellular level, it is possible for them to withstand it.

Orochimaru's use of the cursed seal to achieve this effect is a scientific mutation.

Yubi has always been intentionally refining his physical body, aiming to become stronger—in fact, he is similar to Orochimaru's cursed seal effect, which is also at the cellular level.

This also applies to some of Tsunade's forbidden techniques.

However—Orochimaru's cursed seal is too dangerous and has strong side effects.

In order to achieve stability, Yubi still wanted to follow the path of Tsunade, where her body would undergo a transformation through training using "normal ninjutsu," rather than relying on external forces.

Previously, it would have been quite difficult for Yubi to achieve this step simply through cultivation.

After all, Tsunade's ability to achieve that level is inseparable from her bloodline.

But things are different now.

With the spiritual power granted by the two eye powers and bloodline limits, the control over chakra becomes more refined—in addition, the Crimson Blood Technique itself can control and change the cellular components in the blood.

Therefore, in Yubi's view, it's only a matter of time before Yubi can delve deeper into the "Crimson Scale Leap" technique and achieve the same level of skill as Tsunade.

He wasn't referring to the self-healing aspect of medical ninjutsu; he already possessed the Reversal Technique, so he no longer needed to concern himself with medical ninjutsu.

He was referring to the chakra system at the physical level, and he wanted to find a way to update the chakra system to another version.

But Yubi was also very interested in the method of cursed seals.

Because—this is also a way to improve the fighting strength of Sunagakure.

Now, targeting the Uchiha clan and conducting experiments is just the beginning.
