Reborn Into Naruto World With Tenseigan
Causes of Curse
...'If this poison was related to the Kekkei Genkai of the Kaguya Clan, then why were the members of the Kaguya Clan not immune to this poison?' is the thought in Kuroto's mind....
...Kuroto who had studied, and concocted various types of poisons and poisons, for many years was now no stranger to Poisons, he said, it is not even wrong to say that he is also one of the few shinobi with deep knowledge of both biological toxins and Mineral toxins. Therefore, he quite understands that all animals and plants that carry all kinds of toxins are generally immune directly to their own toxins, he said, or they have a certain mechanism in their body that prevents the poison from harming themselves....
...It's not some sort of magical thing, it's a strict requirement to ensure their own survival. If a species does not have a protective mechanism against the toxins produced by their own bodies, then that species will not be able to survive for long, and will soon become extinct....
...After all, survival of the fittest was no joke....
...However the Kaguya Clan managed to survive for a millennium despite the dangerous poison in their bodies, this showed that the Poison was rooted in their bodies, more specifically in their bones did not directly affect the survival of the Kaguya Clan. What Toxin is limited by is the upper limit of their power and how much they can or cannot use or explore Shikotsumyaku....
...And this unusual restriction somewhat reminded Kuroto of the Mangekyou Sharingan of the Uchiha Clan....
...The Mangekyou Sharingan in the truest sense was merely a product of the deep development of the Uchiha Clan from their own Kekkei Genkai Sharingan. True, there are some additional requirements involving emotional stimulation and others, but in the end, this is still the next stage of their Kekkei Genkai evolution....
...The Mangekyou Sharingan represents the peak of Visual Proficiency that an Uchiha can possess, before losing its light and eventually going blind after continuous use unless he awakens the Eternal Mangekyou Sharingan by taking the eyes of his blood relative, the Mangekyou Sharedan, preferably a sibling....
...However, Otsutsuki Hagoromo and his eldest son, Otsutsuki Indra never faced this problem of blindness, why is that so?...
...Obviously because their Chakras are quite powerful, but that alone cannot be an excuse, after all, if it is only Chakras, so Madara and Sasuke should not suffer from this effect of blindness as they are the reincarnations of Otsutsuki Indra, thus possessing the chakra of the senses. However, they do so and suffer, which means that the powerful Chakra itself is not the key....
...Kuroto attributes this to the depletion of their bloodline. The bloodline of Rikudo Sennin and his son Indra was pure, therefore, they never needed the eyes of their brothers. However, Rikudo Sennin's own blood gradually became thinner and thinner over generations over the course of a thousand years of reproduction....
...Even if the Uchiha Clan took the policy of not letting the Klan's blood flow out of the Clan, or foreigners not getting into the clan, and restricting marriage between clan members only, it would be impossible for the Uchiha Clan to flow out of the Clan, that's not a hundred percent possible.full evidence approach. There must have been hundreds of occurrences in thousands of years when members of the Uchiha Clan were reproduced with non-Uchiha; as a result, giving birth to half of the Uchiha children whose lineages were thinner compared to their parents....
...And this process goes on until the Indra lineage becomes very thin....
...As a result, an Uchiha could not support the large consumption caused by the Mangekyou Sharingan, and his eyes would definitely be sealed the more he used....
...The Uchiha Clan should have been stuck in this matter for many years, but they finally found a solution, namely the Eternal Mangekyou Sharingan....
...That is, with the Mangekyou Sharingan fusion of two blood brothers, preferably brothers; they might be able to pass through the thinness of their bloodline and gain eternal light. In this way, the issue of the thinness of the bloodline was solved fundamentally for a particular Uchiha and his eyes again evolved into the Eternal Mangekyou Sharingan, the Mangekyou Sharingan, which was not blind....
...And for some reason, the Curse of the Kaguya Clan seems to be a little similar to Kuroto, of course, there are many differences, but the issue of the thinness of the bloodline seems to be the cause....
...'Does that mean the cause of this unnatural disease caused by the poison in the Kaguya Clan is also a result of their bloodline becoming thinner over thousands of years?' as this thought came to Kuroto's mind, he quickly realized that if his guess was correct, then the mysterious 'Toxin' rooted in the bones of the Kaguya Clan was not a simple 'Toxin....
...But this was only a guess and not enough to prove Kuroto's theory. So, instead of speculating, Kuroto began to conduct some experiments that would help him understand the true characteristics of this Poison....
...Since the Poison was circulated throughout the body of the Kaguya Clan members with blood as its medium, then Kuroto quickly took a sample of Kimimaro's blood and tried to extract a 'Toxin' from it to research this Poison....
...And the extraction process went quite smoothly, Kuroto quickly identified an unknown toxic substance in Kimimaro's blood, then separated it from the blood using a simple centrifugation process....
...But as the Poison particles were gradually separated from Kimimaro's blood and collected in another solution, Kuroto soon encountered a problem....
...Kuroto was surprised to find that once this 'Toxic' present in Kimimaro's blood was purified to some degree, it became impossible to collect, or rather, impossible to store somewhere....
...There were no vessels in his laboratory that could contain Poison, even if it was made from some of the best and strongest substances ever, they would only collapse in the presence of this poison and turn into ashes....
...Kuroto had never expected that a day would come where she would face such a problem, holding onto a mere Toxin had become an impossible task, okay, not just poison, but I think the main point is clear. There was no equipment in his laboratory capable of accommodating a purified 'Toxin....
...Although she felt troubled, Kuroto did not let it bother her too much, as this phenomenon of things collapsing and crumbling into ashes reminded Kuroto of the effects of Otsutsuki Kaguya's All Killer Ash Bone....
...All Killing Ash Bones Kaguya was able to destroy anything and everything with just one touch and unlike Truth-Seeking Orb, which had a similar effect, in the case of All Killing Ash Bones, was not, even Senjutsu was very useless, so whatever these bones touched immediately collapsed into nothing more than ash....
...After this discovery, Kuroto was more convinced by his guess, "It seems that the Kaguya Clan's ability to control their bones is a much weaker version of Otsutsuki Kaguya's ability to manipulate his bone structure into a Killer Bone."...
...Otsutsuki Kaguya also took out All-Killing Ash Bones from his body, but he remained unharmed from them, meaning that he was immune to the effects of All-Killing Ash Bones....
...But the members of the Kaguya Clan did not....
...Of course, just because Otsutsuki Kaguya was immune to the negative effects of All-Killing Ash Bones did not mean that the Kaguya Clan should also be immune....
...It can also be attributed to Otsutsuki Kaguya as the ancestor of all Chakras. His Byakugan was a true Kekkei Mora, and his body was extremely strong, probably the strongest in the Shinobi World. This meant that his body was strong enough to negate the negative effects of All-Killing Ash Bones....
...And if all of his guesses were indeed correct, and if Shikotsumyaku was a weak version of the All-Killing Ash Bones, then Kuroto felt sorry for the Kaguya Clan, he said, because they are probably the most unlucky of all the descendants of Otsutsuki Kaguya....
...Although the Kaguya Clan inherited the most dangerous abilities from the Otsutsuki Kaguya arsenal, but due to the depletion of their bloodline for thousands of years, they were unable to use this most dangerous ability....
...In the case of the Mangekyou Sharingan of the Uchiha Clan, they only lost their eye light due to their thin bloodline, but in the case of the Kaguya Clan; as the Kekkei Genkai they developed more and more, and more, and when it reached closer and closer to its original form and slowly began to acquire the characteristics of the All Killer Ash Bone, it actually resulted in the death of the Shinobi Kaguya Clan....
...Even if the Kaguya Clan inherits the body of Sage Hamura, even if their Yang Chakra is very strong, even if their physique might be on par with the Senju and Uzumaki Clans, in the presence of All the Slaying Ash Bones, even if their physique might be on par with the Senju and Uzumaki Clans, in the presence of All the Killer Ash Bones, being able to kill even Six-Line level people with just one touch, how could those Kaguya Clan people who were not close enough to Six-Line level shinobi refuse, and not die?...
...After concluding this, Kuroto also understood that the 'Blood Exchange Ritual' used by the Kaguya Clan clan to reduce their blood poisoning rate was actually not a cure, but a self-defeating method for self-defense....
...As the toxicity level in their blood decreased, the speed at which Shikotsumyaku progressed to All-Killing Ash Bones was reduced, so even though the members of the Kaguya Clan could live longer, they did so at the expense of their strength....
...Of course, even these self-defeating methods are not permanent remedies because sooner or later they will die, and this does not change....
...The solution found by the Kaguya Clan was truly incomparable to the Uchiha Clan, The Uchiha Clan had found a method to cut through their thin bloodline and achieve greater power in the form of the Eternal Mangekyou Sharingan....
...But the Kaguya Clan only found a temporary method to extend their lives for a few, and that too after sacrificing many of them....
...Of course, the ancestors of the Kaguya Clan could not be blamed or called incompetent for this, after all, no matter how hard they tried, dealing with the All-Killer Ash Bone was impossible....
...If there was indeed a way to cure the curse of the Kaguya Clan, then it was to possess bodies as strong as Kaguya, Hagoromo, and Hamura, so that the body could withstand the attack of the All-Killing Ash bone....
...Byakugan Kaguya and Rinnegan Hagoromo are Kekkei mora, in fact, Kuroto even speculates that the Hamura Tenseigan might as well be Kekkei Mora, and for how strong their bodies really are, and for how strong they really are, it was very difficult to imagine even for Kuroto....
...And reaching Kekkei Mora was definitely not a joke. Let alone Kekkei Mora, it was a fusion of the seven Traits of Chakras; even reaching the level of the Six Paths with the fusion of Yin-Yang and achieving the Power of All Creation was no joke....
...Therefore, the fact that the ancestors of the Kaguya clan could find a solution to cure the Kaguya Clan Curse was not to blame, at the very least, they found a method to increase their survival rate by using 'Blood Exchange Ritual. .'...
...After everything was said and done, Kuroto could only sigh inwardly, 'No wonder Orochimaru-sama could not save Kimimaro.'...
...In the Canon, it was not that Orochimaru was not trying to save Kimimaro, in fact, he was using everything he could to find a cure from Kimimaro's illness, but he was completely helpless. The lack of knowledge about the Kaguya Clan is one of the many causes of Kimimaro's early death....
...'Heh, it is ironic enough to think that the Curse of the Kaguya Clan is actually a genius disease, the more genius a member of the Kaguya Clan, the sooner he will die.' Kuroto sighed....
...Kimimaro died at the age of 15. He didn't even have the chance to leave behind a descendant....
...However, Kuroto immediately put those thoughts aside, and muttered to herself, “It seems like I won't be using the 'Blood Exchange Ritual'. The so-called ritual is actually self-defeating, not healing, and I obviously don't want to weaken Klon.”...
...Despite this, Kuroto was not too worried, as she was working towards Project Godhood. And Project Godhood will be completed when Kuroto reaches Kekkei Mora. When Kuroto reached Kekkei Mora, his body would be as strong as Otsutsuki Kaguya, so the curse of the Kaguya Clan would obviously be meaningless to him....
