My brother Uchiha Madara

Originally, Uchiha Yu's body chakra amount was limited, after all, the upper limit was there.

Even if he had the Corpse Vein, the chakra was further improved, but it only reached about 1500K, which could not carry the chakra consumed for so many years.

However, after approaching Uchiha Yu, these chakras were still absorbed into the body.

Originally, Uchiha Yu thought something was going to happen, but he didn't expect that during the operation of the chakra root, all the chakras that poured in were compressed and refined step by step during Uchiha Yu's practice.

Step by step, it was transmitted to his Dantian, and then along the Dantian, it stretched to the limbs and bones of the body.

Uchiha Yu's chakra upper limit did not get any improvement in this process.

However, Uchiha Yu clearly felt that those chakras were constantly integrating into his body, causing some changes in his body.

This point is very inconsistent with the law of conservation of energy.

However, Uchiha Yu did not feel any discomfort, but felt more at ease, especially the faint joy in his heart, which was very similar to the feeling when his body's blood was evolving.

This made Uchiha Yu feel more at ease.

As time went on, Uchiha Yu found that his body began to show a state similar to "hair removal and marrow washing".

At first, the body expelled some sour and smelly dirt, not the kind of wisps of mucus, but like staying in a stuffy room in a high temperature of more than 40 degrees.

That kind of filth was constantly expelled as if it was free, and in just half an hour, several kilograms of it were expelled.

While expelling the dirt, Uchiha Yu also began to peel off, layer by layer.

Lost hair, lost teeth, and even the cornea fell off layer by layer.

Even in the end, Uchiha Yu's body no longer flowed out dirt, but blood, which flowed out in streams, making the whole room look like a murder scene.

However, apart from being a little dirty and a little creepy, Uchiha Yu did not feel any discomfort during this process.

In particular, Uchiha Yu weighed his weight and found that he was not lighter because of removing so much dirt, but heavier.

And those fallen hairs grew out quickly after falling, and they were darker and stronger than before, and could be manipulated freely by himself.

After the teeth fell out, new ones would grow out quickly;

After the skin peeled off, the new skin inside was smoother and more delicate, but much stronger than before.

At least, without using any chakra at all, his skin could not be pierced by ordinary kunai at once.

Even if he used his full-level shuriken throwing technique, it only broke a scar.

With his self-healing ability, he recovered completely in just a few minutes.

All this is moving in a good direction.

In this constant change, Uchiha Yu also vaguely guessed the reason for the change in his body.

Chakra transformation!

Or, to put it in a more understandable way, he is transforming into a human-shaped tailed beast.

Tailed beasts are nine kinds of monsters created by the Six Paths Sage after dividing the energy of the Ten Tails.

No matter what abilities and attributes these nine monsters have, they all have one characteristic.

That is, although they are entities with flesh and blood, they can also become energy bodies.

This is a kind of existence that can transform between chakra energy bodies and flesh and blood bodies.

Therefore, the tailed beasts can be sealed in the human body through sealing techniques;

Therefore, even if the tailed beasts die, they will be resurrected after a period of time when their chakras are aggregated.

At this moment, Uchiha Yu, under the Chakra Root Technique, has reached a level similar to that of the tailed beasts.

His chakra is evolving into his flesh and blood tissue, replacing his original body bit by bit.

Therefore, he did not feel any discomfort, and even felt a sense of peace of mind.

Because as the chakra is transformed, his body is gradually losing its weaknesses.

He is developing in a more advanced direction.

Chakra Root Technique.

At this moment, Uchiha Yu gradually understood the meaning of this technique.

The origin of chakra comes from the sacred tree.

Or, from Kaguya Otsutsuki.

She planted the sacred tree herself, and finally ate the core fruit of the sacred tree, instantly becoming a great existence.

From that moment on, all the chakras in the world, except for the hidden few Otsutsuki, have the mark of Kaguya.

The reason why Otsutsuki Hagoromo and Otsutsuki Hamura had the opportunity to rebel against Otsutsuki Kaguya was because when Otsutsuki Kaguya was eating the fruit of the sacred tree,Pregnant with two people.

Part of the power of the core of the sacred tree was stolen by the two brothers.

To some extent, the two brothers have the same level as Kaguya Otsutsuki, and therefore have the possibility of resisting Kaguya Otsutsuki.

If not, it is estimated that the sealing of Kaguya Otsutsuki would not have happened.

Uchiha Yu, who practiced the Chakra Root Technique, became another independent existence, making Uchiha Yu the third independent existence outside of Kaguya Otsutsuki's will after the Six Paths Sage, Otsutsuki Hagoromo, and Otsutsuki Hamura.

Perhaps his current physical energy is not enough to compare with those perverts of the Otsutsuki family, but his status is equivalent.

His chakra belongs only to him.

Even if it is used, as long as the chakra is not decomposed by the heaven and earth, he can summon it back.

And his chakra seeds have now become chakra root seeds, which completely eliminates Uchiha Yu's last worries.

The chakra root seed can be destroyed and studied, but it cannot be replaced.

Because above the root, the chakra root seed belongs to Uchiha Yu's characteristics.

This characteristic is like the relationship between the characteristics of the sacred tree and chakra.

Without the characteristics of the sacred tree, there is no chakra.

Without the brand characteristics of Uchiha Yu, there is no chakra root seed.

If you want to enjoy the benefits of Uchiha Yu's roots, but don't want to be harvested by Uchiha Yu, you are dreaming.

Time passed leisurely, and seven days passed~

Uchiha Yu finally stopped practicing the root technique.

It's not that he doesn't want to continue, but there is no chakra in the outside world.

At this moment, his chakra is still 1500 calories.

If it were before, if he consumed all the 1500K chakra at once, he would need an hour to completely replenish his chakra with the mental amplification brought by the primary sage body and the Sharingan.

But now, after consuming it, he can use the chakra refining technique to replenish his body's chakra to the upper limit within a few breaths, because a large part of the cells in his body are now made of chakra.
