In Konoha Village, Uchiha Kai sat quietly in the room of the underground laboratory.

The chakra on his body surged extremely fast, but the originally complicated chakra seemed very quiet under his control.

The strangest thing is that those powers with completely different attributes and auras are completely blue at this moment, and they are completely resonating with his own chakra.

Fusion of chakra is not an easy thing, it is the same for everyone.

After all, this is a way to fusion blood transcendence limits, and the more fusions it is, the more unimaginable the power it presents!

Uchiha Kai and others were lucky. With the help of Iori, they had long turned the impossible into something that could be done, and they all reached the level of fusing at least four chakras!

Kenta Imai is the most powerful guy among them. His five chakra fusions were completed before Uchiha came back.

I have to say that this guy does have an unimaginable talent. Before Iori completely cracked the blood secrets of the Yuyi clan, he had already found a breakthrough in the fusion of five attributes.

And he began to try to use this breakthrough, allowing his chakra to truly precede Iori's research and embark on the path of fusion of five attributes.

It can even be said that Iori's subsequent research also borrowed a lot of this guy's ideas, and combined with the bloodline research and development progress of the Yuyi clan, this fusion method was completely cracked!

"call....."

When the five different attributes of Uchiha Kai's body were completely synchronized and began to resonate with special resonance, he finally breathed a little relieved.

Complete this step can basically be regarded as a step that he did the fusion of five attributes as a troublesome step.

The rest is to accelerate the synchronization of their own chakras and allow them to be completely integrated.

Since he began to study the bloodline of the feathered clan and began to try to integrate it, he has long been accustomed to these things after so many years.

Moreover, in addition to the extraordinary difficulties at the beginning, such fusion is basically the same in the future. It is just a step of constantly familiarizing, mastering and thoroughly improving.

"It seems that you're done." At this moment, the door of the room was opened, and Hinata walked in slowly and closed the door behind him.

"Well, I'm done for the time being." Uchiha Kai nodded with a smile: "The most troublesome sync fusion has ended, and the rest is relatively easy. Although it's also very troublesome, we are all used to it, aren't we?"

"Indeed, it was much easier afterwards." Hinata Aya walked slowly to Uchiha Kai's side, and then slowly sat down: "After all, we have experienced so much, so we can be considered familiar with it. However, I have always had a problem that I didn't understand."

"I just don't know why I've been emphasizing that fusion of chakra?" Uchiha Kit tilted his head. He knew that Hinata Aya was probably wondering what she was now without asking.

Actually, this is not surprising. Their current strength is really too exaggerated.

Even sixteen or seventeen years ago, they had just joined together and never thought that they would now cross this point.

Perhaps Uchiha Kai had thought that after all, he knew how exaggerated the enemies he would face in the future.

But when he really got to this point, he was a little surprised and incredible, not to mention Hinata Aya and the others.

Moreover, at their stage of strength, the power of the blood-resistance limit is probably just that. Even if the student status is eliminated, it is just a chakra expression with a little bit of strength.

The chakra modes of Uchiha Kai and Hinata Aya can easily condense the Jade of Seeking Tao.

Moreover, as their power continues to increase, even if they do not use the chakra mode, they can show the Jade of Seeking Tao.

After years of training, learning and accumulating chakra, all their attributes of chakra are kept at the same extremely high level.

In addition, they are people with Yin and Yang escape, so it is not difficult to gather the Jade of Tao. At most, there are fewer numbers, and there is no way to compare with the chakra mode.

That's why Hyuga Ayan feels strange, why did Uchiha Kid have been investigating the fusion of Carra from beginning to end?

Even though his strength has reached this point, he has been persisting and has never given up.

"Yes." Hinata nodded slightly: "I am really curious about this. The fusion of chakra is very strong, but it seems to have helped us too little. Even Kenta, a guy, has a tailed beast chakra mode, and the combat level he shows is not weak."

"Yes, indeed, we are all very strong." Uchiha Kai nodded. He did not deny Hinata Aya's intention: "But there is one thing you probably didn't expect, not only you, but Kenta, also."

"What is it?" Hinata Aya was also very curious. She was not in a hurry now, so it was no big deal to figure out some of these things.

"That's the essence of chakra."

Uchiha Kai smiled a little, and he raised his hand to help Hinata Aya stroke his hair before saying slowly.

"Does it feel natural to fight with chakra? But I think few people think about one question, that is, what is the essence of chakra.

In fact, Chakra's research has become more and more in-depth and extensive, and the development progress has become higher and higher, and is moving towards once unimaginable progress.

But few people really look back and start studying some basic, mysterious and important things.

Deformation, qualitative change, power improvement, etc., as well as various chakra development techniques, which are considered to be advanced chakra usage techniques.

With our strength, such development skills are actually not difficult for us at all. We can do whatever we want.

However, we rarely explore basic things, and chakra fusion is actually a kind of basic exploration.

The blood-resistance limit makes us stronger, but why can the blood-resistance limit appear in the fusion of two chakras?

No one knows about this kind of thing, and we are not interested in studying it. This ‘we’ includes other ninjas.

In my opinion, this is not a good result, and of course it cannot be considered a very bad result. After all, we don’t have that much time.

But we can't figure out the problem of blood transit limits like this, but we can reversely introduce other things, such as..."

Uchiha Kirinlin said a lot of things, and Hyuga Aya listened very seriously, Uchiha Kirin said very well.

Indeed, with the widespread use of chakra, advanced ninjutsu and various techniques have been developed, but no one has explored the most basic things.

The fusion of chakra attributes is a very basic topic, and there is even a topic like "Where does the power of chakra come from?"

Perhaps Orochimaru will be interested in these things, but Uchiha Kai's interest is not that high, because they know where the chakra is. Even if they don't know, they really don't have time.

Moreover, as Uchiha Kai's words continued to deepen, Hyuga Ayan also roughly understood what he meant.

The blood-resistance limit is the fusion of two chakras, which can separate two basic attributes of chakras.

Three types can be separated by elimination of bloodstains, and there is another key. Chakra, which masters and balances seven attributes, can condense the jade for seeking Tao.

So, if all the attributes of chakra can be integrated together, can we reach an amazing conclusion - the power of the ancestor of chakra, or her bloodline?

"You mean..." Hinata Aya raised her head slightly incredible: "Through the fusion of chakra, we can obtain... no, the bloodline of the ancestor of chakra?"

"To be precise, it is the power in the bloodline." Uchiha Kai gently stroked Hinata Ayan's face, then sighed slightly and said, "In fact, you and I have bloodlines, and there are even many people in the entire ninja world who have the ancestor bloodline.

But having is one thing, how to develop is another. Just like us, it can be said that it is very good to develop.

But I don’t think this kind of power alone is the entire power of the so-called ancestor bloodline in my mouth.

Of course, even fusion of chakra cannot be considered as such.

We should take it apart and see that the power we get is the power given by the body itself as a race.

The power of chakra should be regarded as a new inherited power obtained through practice or devouring fruits later."

Uchiha Kai said that he had stopped here. In fact, in his opinion, he always felt that the so-called power of Otsutsuki should be regarded as two parts.

One part is the power they have as this race.

For example, rolling eyes, reincarnation eyes, etc., the power of inheritance based on bloodlines.

Another part is that after devouring the fruits of the sacred tree, they obtained the power of the huge chakra that was unattainable.

That is, the so-called most original power of chakra - the power of blood relay.

And this part of the power Uchiha Kishi really knows one thing. If you want to completely restore it, you must integrate seven different attribute chakras including Yin and Yang escape!

Nowadays, Uchiha Kai, Hyuga Aya, and Kenta Imai have no idea of ​​the development of his own bloodline.

Then there is only one left that is worth their expectations, that is, through the fusion of chakra, we can trace back the power obtained after devouring the fruits of the divine tree.

This is the power that belongs to the essence of chakra!

"I really didn't expect that you actually thought of something so far away." After hearing Uchiha Kai's words, Hinata couldn't help but sigh: "You started preparing more than ten years ago. Did you think of it at that time?"

"It's considered a good deal, but it's not." Uchiha Kiyo shook his head. He couldn't tell all of his words, even if they were the ones they trust the most: "I just had a concept or a guess at that time."

"Conjecture?" Hinata Aya asked strangely: "What kind of conjecture is it that makes you make such a crazy decision to merge chakra?"

"Because of that old man Onoki, because of dust escape." Uchiha Kai threw a black pot on Onoki's head without hesitation.

This reason really has a bit impeccable meaning. After all, only the old man who lives in the entire ninja world will be eliminated in blood.

And the strength he showed was really terrifying. It was normal for Uchiha Kai to have thoughts about these things more than ten years ago.

And he also said that he had already had a guess at that time. Maybe this guess would be a fusion of all chakras, which would be even more than blood-stained elimination.

"So, what made you completely affirm?" Hinata Aya looked up and down at Uchiha Kei: "The rotation of the thousand-year memory? The ancestor's notification? Or..."

"The memory of Otsutsuki Ichishi." Uchiha Kai decisively spread his hands: "You have seen it, I imprisoned his consciousness, and I have also seen a lot of memories through his consciousness, including all the information about the fusion of attribute chakra."

"Is Otsutsuki Ichishi?" Hinata nodded: "Okay, it's really this guy. Actually, if you think about it carefully, only such guys can have such detailed information."

"Yes." Uchiha Kai nodded, "It's really very detailed."

Speaking of this, Uchiha Kiyo shut up decisively.

He is very clear about the truth that he can say too much. It is enough that half of his words can make others understand what they mean.

Although the prisoner who stayed in his consciousness space would not jump up to refute him, Uchiha Kai's lying to Hinata Aya made him feel a little uncomfortable, and the topic was so good that it was so far.

Besides, this conversation can be said to be very complete, although he didn't know what happened to Hinata Aya coming to him.

However, it would be great to explain the problem of Xueji.com clearly. With this information, he would not believe that Hinata Aya and Imai Kenta would not work hard.

"By the way, how is Kakashi and the others going on?" Perhaps because he knew the answer he wanted, Aya Hinata simply changed the topic: "They went to save Shizuriki, and it seemed that they had been going on for several days. There was no accurate letter to the specific situation."

"I don't know very well, but such a task cannot be difficult for Kakashi." Uchiha Kai shook his head casually: "You must know that except for a few people, the entire Akatsuki organization is all our own people. What I care most about now is the situation of those little guys."
