Have you seen enough?
After a while, Tsunade stretched, and her loose white coat couldn't hide her stunning figure that stood out in the Shinobi World.
"Not enough."
Yuzuru placed his hands on Tsunade's shoulders and gently massaged them.
"I haven't seen a teacher this serious in many years. The last time I saw a teacher this focused was when we were researching Ice Release together."
Upon hearing this, a flicker of reminiscence crossed Tsunade's eyes.
"Back then, you were just a little kid."
"And now?"
"You're such a disrespectful little brat!"
Yuzuru:...
"You've caused quite a stir in the Shinobi World lately."
Tsunade glanced at him.
"Well enough."
"As for the Kekkei Genkai Disease, I've dealt with most of the others except for Itachi's."
"So fast? You truly are my beloved teacher!"
Yuzuru looked at her in surprise.
Ignoring how Yuzuru addressed her, Tsunade picked up the blood analyzer.
" The Kaguya Clan has a lot of problems with Kekkei Genkai Disease, but as long as they don't pull out too many bones, it's fine. Their bloodstains are very strange, how should I put it?"
The Shikotsumyaku granted them superhuman physical abilities and bones far harder than steel. However, the problem is that each time they use their bones, it reduces the stability of their genes, meaning there's a limit to the number of times they can use them.
"My advice to them was that they should not frequently pull out their own bones or use those strange secret techniques, such as the Ten-Finger Drilling Bullets. Instead, they should honestly practice Taijutsu and avoid using their own bones unless absolutely necessary."
In that case, their physical strength could remain at a terrifying level forever. Although they would lack those offensive techniques, at least they wouldn't develop Kekkei Genkai Disease.
"Pure Taijutsu? That's not a bad direction."
Yuzuru had no regrets about this. After all, the Kaguya Clan's physical attributes were what they were; even in their normal state, they possessed a hardness comparable to steel. With a little training, each of them would become an extremely powerful close-combat killer.
"Speaking of Kimimaro? I remember that kid was born with Kekkei Genkai Disease."
"Yes, his parents experienced the bloody policies of Kirigakure back then. After intense battles, both of them developed Kekkei Genkai Disease. Kimimaro was born under those circumstances, so his genes are much weaker than those of the healthy Kaguya Clan. Fortunately, you didn't let him continue training or practice those secret techniques, otherwise, he probably wouldn't have lived for more than a few years."
Tsunade took out Kimimaro's blood analysis report and said...
"I have prepared a suitable serum. Based on his condition, it will take about a year for him to recover. However, his genes are still very fragile, so I will not recommend using bone in the future."
"That's alright. Most Ninjutsu and secret techniques will become obsolete sooner or later. The future belongs to the technological age. Scientific Ninja Tool can do anything. Compared to that, Chakra is the most important thing."
Yuzuru understood this very well. The Shinobi World of the future was no longer a world of ninjas. If he were allowed to continue along the original path after coming to this world, wouldn't he have come for nothing?
As long as he has Ice Release, he is invincible.
Unless the opponent disregards the fundamental laws of the universe, but is that even possible?
"I need to continue researching Itachi's situation. This kid is very strange. You might think he has Kekkei Genkai Disease, but his Mangekyō is right there, and his genes are very stable."
"But if you say he's healthy, well, when he's not using the Mangekyō, his genes are very unstable. And every time he activates the Mangekyō, his genes break down even faster. It's very strange. The Mangekyō Sharingan seems to be protecting his genes, but the side effects of the Mangekyō Sharingan are accelerating the collapse of his genes."
Every time Tsunade sees Itachi's blood analysis, she feels her worldview being shattered and rebuilt.
Is this thing really the same as those Kekkei Genkai Disease?
"Now?"
"It's not entirely hopeless. I'm currently trying to strengthen Itachi's body using Sasuke's blood, and so far, it seems to be very effective."
"It's strange, Sasuke's blood and genes are so different from Itachi's. Aren't they brothers?"
Tsunade picked up Sasuke's blood sample and looked at the genetic data of the two brothers, but she really couldn't understand it.
"Physiologically speaking, Sasuke and Itachi are indeed biological brothers, but Sasuke is the reincarnation of Indra, in other words, the reincarnation of the ancestor of the Uchiha. Although Indra has long lost consciousness, his unique Yin Release and talent still exist. Perhaps this is why Sasuke's genetic strength far surpasses Itachi's."
Yuzuru and analyzed.
"It's not impossible. In short, Sasuke's blood would have an effect on Itachi. After being injected with Sasuke's blood, Itachi's body would quickly absorb the nutrients. However, this is only a temporary solution."
Tsunade sighed.
" Sasuke is still young, we can't expect him to keep donating blood to support Itachi, can we?"
"Well, given the Uchiha Clan's tradition of brother-complex and brother-complex, Sasuke might actually be proud of it?"
Hearing this, Tsunade rolled her eyes at him.
"At this rate, Sasuke might become malnourished."
" Orochimaru is also researching Itachi's genes, but he's not making much progress. Oh right, did you know that he has two divine artifacts hidden in his Mangekyō Sharingan?"
"Of course, the light has already Imprinting those two things on it."
"I'm wondering if those two things are influencing Itachi."
"That's possible. After all, Itachi was the first to wield Susanoo with divine artifacts, and he even possessed two divine artifacts."
"Such immense power might be beyond Itachi's complete control at his current level."
At this point, both of them fell silent.
"I suspect that Itachi's body couldn't withstand the power of those two things."
Tsunade told the truth.
"In the history of the Uchiha Clan, no one has ever awakened the Mangekyō Sharingan at Itachi's age. Moreover, his Susanoo two sacred artifacts. If he had awakened it after reaching adulthood and his body had fully developed, it might have been normal."
"Or, things might be much better once he's a healthy adult and his body has fully developed."
"The problem is, Itachi might not even live to adulthood now."
Tsunade:...
"Is it possible that we can only rely on that kid Sasuke to prolong our lives?"
Their eyes were filled with helplessness.
While massaging Yuzuru 'Tsunade shoulders, Yu Gen also pondered a solution.
I'm going to the moon this weekend.
"That progenitor of Chakra?"
"Hmm, perhaps she has a way."
"If not, ask her if there's a way to seal the Mangekyō Sharingan. If Itachi temporarily loses this power, maybe his body will stop collapsing, and it can be unsealed when he comes of age."
Tsunade offered her own idea.
"This method does have some feasibility."
Yuzuru strongly agreed with this method.
Since it's impossible to fully control it, it's better to seal it temporarily and return it to Itachi once his body has fully developed.
"If there's really no other way, then we'll have to resort to the worst method."
"What?"
"Surgery will remove the Sharingan, and it will be temporarily sealed away until he reaches adulthood, at which point it will be returned to him."
"Well, it's one way, I suppose."
"That was the only option available."
