The man standing at the top of the ninja world

Therefore, for the benefit of Konoha, even if Nagato, a kinsman, is sacrificed, it is a matter of course. It is impossible for Uzumaki Mito to oppose Danzo's suggestion just because he is a kin with Nagato.

And this was indeed the case. After Danzo finished speaking, Uzumaki Mito did not show any intention of speaking, but remained silent.

But Uzumaki Mito's silence did not mean that others did not have different opinions. Before Danzo could be proud for a few seconds, someone else raised objections.

"I don't agree to do that."

Sarutobi Hiruzen looked at Danzo with an unquestionable look in his eyes, "We all know the Kyuubi's ability, and it was judged by Mito-sama himself. In this case, there is nothing to doubt at all, Chang. He has no ill intentions towards Konoha, this is an undisputed fact."

"Danzo, don't you think Naruto represents Konoha enough?"

Danzo's expression changed, Sarutobi Hiruzen's words touched a painful spot in his heart.

Of course the Hokage can represent Konoha, but unfortunately it is not him who is the Hokage, but someone else.

"Sarutobi, you" Danzo opened his mouth to speak, but as soon as he started speaking, he was forcefully interrupted by Sarutobi Hiruzen.

"Also, Danzo, don't forget that transplanting the samsara eye is not that simple. What if there is a rejection reaction?"

"This" Danzo originally wanted to argue, but the words "rejection" seemed to have some magic power, and he suddenly choked back what he was about to say.

Mito Uzumaki, Kado Yan, and Koharu who had been standing aside silently watching the two of them arguing, their expressions changed slightly when they heard Sarutobi Hiruzen's words.

Everyone present knew very well what rejection was.

The so-called rejection reaction, simply put, is an adverse reaction caused by the body tissue of one person being transplanted into another person's body. Due to the physical differences between the original owner and the new owner, the original owner's body tissue does not adapt.

In the ninja world, the thing most closely related to rejection reactions is the blood inheritance boundary.

As we all know, the Blood Succession Limit is a combination of two attributes. For example, Ice Release is water plus wind, and Wood Release is water plus earth. Therefore, at the same level, ninjas with Blood Succession Limit release ninjutsu. The power is obviously stronger than the ordinary Five Elements Ninjutsu ninja.

Ninjas are all eager to become stronger. In this case, those ninjas who only know the Five Elements Ninjutsu will naturally have the idea of ​​​​allowing themselves to have the blood inheritance limit.

However, the reason why the Blood Succession Limit is called the Blood Succession Limit is because it is a special power that can be inherited innately through blood, rather than something that can be learned later like Five Elements Ninjutsu or Taijutsu.

However, among the many blood inheritance limits, there are two exceptions, namely the Byakugan of the Hyuga clan and the Sharingan of the Uchiha clan.

These two blood successor limits are different from the blood successor limits of the chakra attribute type such as Ice Release and Wood Release. They belong to the blood successor limits of body organs. In other words, as long as you can grab the Byakugan and Sharingan, then By transplanting them into your own body, you can gain their power.

The Uchiha clan and the Hyuga clan are both well-known wealthy families in the ninja world, and the Uchiha clan is a contender for the strongest family, but no matter how strong they are, they cannot cut off the common ninjas in the entire ninja world from these two eye techniques. of spying.

Before the first Hokage established the ninja village system, the ninja world lasted for more than a thousand years during the Warring States Period. In this long history of ninja wars, although the two major families were powerful, they could not win every battle, let alone without casualties. In the war, Countless people died in the war between the two clans, and these two pupil techniques would sometimes be captured by the enemy.

Among them, the Hyuga clan has caged birds, so most of the captured Byakugan have become waste. However, the war has lasted for thousands of years. No matter how small the Hyuga clan is, they will always die on the battlefield, and Uchiha does not have caged birds. , even more intact Sharingan were captured.

At first, the ninjas who captured these two eye techniques would eagerly replace their eyes to strengthen their strength, but after a while, few people were willing to do this.

This happens because of the existence of rejection reaction. After non-Uchiha and Hinata ninjas transplant these two kinds of eyes, although they can have the abilities of these two kinds of eyes, they are not only limited by the ability of these two eye techniques. In terms of performance, he is not as strong as the two clans of ninjas, and his strength is decreasing instead of increasing, and his strength will grow slower and slower in the future.

Over time, even if someone gets these two kinds of eyes, they are basically unwilling to transplant them into their body.

There are many genius ninjas who have lost themselves to others because of transplanting these two kinds of eyes. This is a bloody lesson.

The five Sarutobi and Hiruzen had a deeper understanding of rejection reactions. After the death of the first Hokage Senju Hashirama, they wanted to copy the first Hokage's invincible Wood Release and let the Wood Release reappear in Konoha. .

To this end, they conducted many human experiments using the first-generation cells, but the results were all failures without exception. Ordinary ninjas simply could not withstand the power of the first-generation cells. Let alone learn wood escape, they would suffer from the effects of transplanting the first-generation cells. Death from rejection.

So far, hundreds of Konoha ninjas have died for this experiment.

"Humph."

But now that Danzo had spoken, he was not going to give up so simply. He snorted coldly, "Sarutobi, the Rinnegan Eye is the eye of the legendary Sage of Six Paths. I have never heard of any family that can awaken the Rinnegan Eye. There is no evidence." It can prove that the Rinnegan, the Sharingan, and the Byakugan are both blood successors."

"In this case, how can we say that transplantation of samsara eyes will cause rejection reactions?"

Sarutobi Hiruzen said disapprovingly: "So what? Before Lord Hashirama was born, no ninja in the Senju clan had ever possessed the wood release ninjutsu. Does this mean that wood release is not the limit of blood inheritance?"

"The Rinnegan is an innate power that Nagato possesses. This is certain. Since ancient times, the Rinnegan has been listed as one of the three major pupil techniques along with the Byakugan and the Sharingan. These rumors cannot be groundless. Since they have been If they are listed together, they must have something in common, and the reincarnation eye must be the limit of blood inheritance."

"Just like Hashirama-sama is the first-generation owner of the Wood Release, maybe Nagato is also the first-generation owner of the Rinnegan."

The era of the Sage of Six Paths is so far away that even the Sage of Six Paths himself is not regarded as a real person by the world. Hiruzen Sarutobi can only make some speculations from some of the only rumors related to the Rinnegan Eye, without knowing anything about it. My thinking is completely wrong.
