Shikamaru explained in detail the causes and consequences of this mission to the second Hokage, and the second Hokage who used Shikamaru's body frowned slightly: "Uchiha......"

"That's not the case, Nidaime Hokage-sama!" Shikamaru, who shared the same body with Senjuma, sensed Kazuma's displeasure and hurriedly added:

"Sasuke is our companion, and although I don't know why he chose this path, he loves Konoha Hidden Village as much as we do......"

"Except for a few individuals in the Uchiha clan who can transcend the narrow family thinking, the rest of the people regard their own families more seriously than Konoha!"

Senju said disdainfully, "But since you think he is your companion, I will help you bring him back!" ”

"Damn!" Naruto suddenly jumped up at this time, pointed at the second Hokage and said loudly:

"Don't think that you are the former second-generation Hokage, you can talk nonsense, Sasuke must have been deceived by that group of people to leave Konoha Village!"

Senju seemed to be stunned for a moment, and glanced at Naruto with strange eyes, as if he remembered someone. Pen & Fun & Pavilion www.biquge.info

"Niyome Hokage-sama, Naruto is like this, please don't blame him!" Shikamaru said a little nervously.

Then the voice switched to the voice of the second Hokage:

"Yay...... How come, little one, what's your name! ”

"Huh?" Naruto turned his head from side to side, and when he saw that the second Hokage was pointing at him, he said in a very confident tone:

"My name is Naruto Uzumaki! It's the man who will become the Hokage in the future! ”

The second generation Hokage was stunned for a moment: "The Vortex Clan?" ”

"Huh?" Naruto, who had always been an orphan, didn't expect that the second Hokage would actually hear of his surname, and he was a little dumbfounded.

Ning Ci frowned, very interested in Naruto's information: "Second Hokage-sama, do you know Naruto's family?" ”

"No one knows anymore...... Thousand Hands sighed slightly: "Sure enough, it's the same as the Thousand Hands Clan, it's gone......

Looking at Naruto and Ninji's serious expressions, Senju began to explain:

"The Vortex Clan is a distant relative of the Senju Clan, and has a deep bond with the Senju Clan since ancient times, after my eldest brother, the first Hokage-sama, established the Vortex Village in the Land of the Vortex Tide. It is a family with a strong vitality and chakra volume. ”

Naruto was a little excited: "Could it be that there are still my clansmen in the Vortex Village!" ”

He shook his head:

"From your reaction, I know that there should be basically no other people like the Thousand Hands Clan...... Since you were born in Konoha, judging from the relationship between Konoha and the Vortex Clan, you should be the clan bloodline of the Vortex Clan...... Is there even a point where there is no inheritance......"

Ning Ci seemed to hear something from the melancholy tone of the second generation Hokage, and asked with some doubts:

"The second Hokage-sama, I've always had a doubt, the Senju clan, who is the founder of the village, seems to be unable to find any other clansmen other than the newly appointed Hokage-sama...... This ......"

"The new Hokage, Kozuna......" Senju seemed to smile:

"A Thousand Hands...... Because there aren't many babies born at all......"

“！”

Kazuma began to recall: "The Senju clan used to implement a system of intermarriage within the clan and relatives, that is, they basically did not intermarry with other families except with the Vortex clan.

"But since the establishment of the ninja village, for the harmony of the whole village, the Thousand Hands clan has broken the intermarriage system within the clan that has been maintained for thousands of years, and began to intermarry with various families and non-family ninjas, and since then, the birth rate of the Thousand Hands clan has begun to plummet, but the Uchiha and Hyuga clans, who have maintained the original system, still maintain a strong birth rate."

"In order to solve this problem, I invested a lot of manpower and material resources to start the research ...... forbidden arts" (The second generation can study so many forbidden arts, it should not be his work alone, it should be a group work.) ）

"Did you solve the problem?" Ning Ci asked.

"The problem is found, but there is no ......solution at all," the second generation Hokage sighed again: "My research has found that there are some essential differences between ninjas and ordinary people in the most basic life composition, the stronger the family, the greater the difference between ordinary people, and as a thousand-armed clan, after intermarrying with ordinary people, this essential difference makes it very difficult for the two to have the next generation......"

If Iruka were here, then he would say to the second Hokage in a strange tone, "Friend, do you know about reproductive isolation? ”

Yes, after the big teacher system scanned the physique of Xiao Li, Yakumo, Hinata, and Naruto, the big teacher system gave an answer that Iruka did not expect.

These four people are slightly different in terms of genetic level, among which Xiao Li's genes are the most similar to ordinary humans, and Naruto's relationship with ordinary humans is probably similar to the relationship between mutants and humans.

Only then did Iruka understand the most critical setting hidden in the Hokage, why the entire ninja world was fighting around, which was actually a family ethics drama of the Otsuki family. Because the Otsuki clan is a human from another world, although it is also one of the countless humans in the pan-plane, it has actually gone in two completely different evolutionary directions from the humans in the ninja world.

Those powerful ninja families and blood succession families are genetically closer to the Otsuki clan than ordinary humans, so naturally the best and most powerful ninjas must be the direct descendants left by the Six Dao Immortals, those who directly possess the blood of the Otsuki clan, such as the Thousand Hands, Uchiha, Hinata, and Vortex clans!

Although the Sacred Tree and the Chakra Fruit are actually products of the ninja world, since Otsuki Kaguya took the Chakra Fruit and became the source of the Chakra, she has completed a new evolution under the influence of that mysterious fruit, which can be seen from her and her two sons, they are different from humans!

Six Dao Immortals, the founder of the Ninja Sect, as an immortal, he shared his chakra with his disciples, but in order to allow his disciples who are just ordinary humans to use chakra, he should use techniques such as "Izana Branch" to share some of his life characteristics with his disciples, which also makes various bloodstain families appear in the ninja world.

The blood inheritance boundary in the ninja world is generally divided into two kinds, one is the blood inheritance boundary above the retreat technique, the mainstream explanation is: this blood inheritance boundary is reflected in these meridians are different from ordinary people, they only need to use one hand to complete a chakra refinement, and then as soon as the hands are closed, the new attribute of the retreat technique appears!

Then a new problem arises here...... What is the situation of the elimination of the bloodstains of the three attributes, and is one foot also involved in the refinement? In fact, it was not the same thing at all, and the reason why they were able to combine two or three basic retreat techniques to create a new retreat technique was entirely because these people were gradually approaching the blood inheritance ability of the big barrel wood clan on some level.

And others are more tragic, they have physical mutations, such as the Kaguya clan of the corpse bone vein, all kinds of pupil arts, the illusion of the Kurama clan, etc., these families can be traced back directly to the big barrel wood family, that is to say, these families actually have the blood of the big barrel wood family, so you will find that these families are more or less blood succession disease.

Genetically speaking, the so-called hemostain disease is actually a rejection reaction, human genes do not accept this organ from another world, so there are all kinds of problems, the only few families that do not have hemostain disease are: the Hyuga family (caged birds are not counted), the Thousand Hands family and the Vortex family. (The Uchiha clan, except for the two cheap sons of Rokudo, who opened a kaleidoscope and lived past the prime of life?) The Fugaku that Kishimoto added in order to fill the pit is not counted...... ）

We know that the Hyuga clan is actually a direct descendant of Hamura, and the bloodline of the Thousand Hands clan is not the original Mu Dun at all, but the same "immortal body" as the Vortex clan! Otherwise, the bloodstain limit of a fusion of two attributes is stronger than the bloodstain elimination of the fusion of three attributes, which in itself is not in line with the Basic Law, and the reason why Mu Dun is strong is because the founder and user are the sons of the Six Dao Immortals in a certain sense!!

So why don't these three tribes have bloodstains? We know that rejection is the body's rebellion against foreign organs, but people themselves are descendants of otherworldly beings, so where does rejection come from!! Therefore, the Six Dao Immortals will give the name to the younger brother who has inherited the "Immortal Body" instead of the elder brother of the "Immortal Eye", because in terms of blood, it is indeed the younger brother who is closer to him......

The Six Dao Immortals and the immortals in the immortal body confuse most people, because in everyone's opinion, the so-called immortals are actually the products of people who have reached a certain realm after cultivating, and they are also one of the evolutionary directions of human beings. But the immortals in the ninja world in the world are actually better understood as "non-human".

This is also the reason why Iruka must send Sasuke to Orochimaru's place to steal his technology and experience in human experiments, the key to changing the ninja world has always been in Orochimaru's hands, but Orochimaru has used them to pursue his own immortality.
