My brother Uchiha Madara

Uchiha Yu had a good idea, and he did it with excitement.

Unfortunately, he found out that he was naive in the end.

After accumulating nearly 1,000 crow shadow clones, Uchiha Yu could not continue.

There are two reasons.

First, the spiritual space hidden in the shadow is not enough.

After the shadow crow contract, each shadow crow will merge with the shadow of the contractor, and to some extent, build a nest in the shadow of the contractor.

This nest will not be very large because there are only one or a few shadow crows.

One thousand is the limit of the shadow crow space.

To increase the space, the number of real shadow crows needs to be increased to expand the shadow crow spiritual space.

Second, he does not have enough chakra.

A thousand crow shadow clones, practicing diligently at the same time, this process is a continuous consumption of the crow clones.

In order to keep the crow shadow clones from dissipating, Uchiha Yu has to replenish the consumed chakra energy of these crow shadow clones every day.

Even if a crow shadow clone tries not to practice those high-cost ninjutsu as much as possible, the consumption of more than a thousand of them is there, enough to make Uchiha Yu drink a pot.

At this moment, Uchiha Yu understood that he had reached a bottleneck again.

The problem of the shadow crow space is easy to solve. As long as you continue to practice the summoning technique, you can make the space in the shadow space more closely connected with the summoning world of the shadow crow clan.

At that time, the space of the shadow space will become larger and larger, attracting more shadow crows from the ancestral land of the shadow crow.

I heard from Uchiha Tajima that a powerful ancestor of their Uchiha clan used this method to trick the entire shadow crow clan.

Yes, they invited them here.

When the compensation points are enough and the summoning technique is activated, the space will basically not be a problem.

Even, maybe you can use this to study the spatial characteristics of the summoning technique and develop some so-called time-space ninjutsu.

I have to admit that the Flying Thunder God Technique makes Uchiha Yu very envious.

He doesn't have the talent of Senju Tobirama, but Senju Tobirama doesn't have his cheats.

However, Uchiha Yu is still taking steady steps and focusing on increasing the amount of chakra.

"My current chakra, in addition to the growth brought by physical development, only has the increase when the Sharingan awakens."

"But I don't have a cheat like Madara."

"Even if I open the three magatama, or even reach the Mangekyō or the Eternal Mangekyō, my own chakra is not enough to maintain my unscrupulous use of ninjutsu."

"The real chakra big user is still the immortal body created by the Asura Yang escape in the body of Senju Hashirama."

"Even the Yin escape in Indra's body is also necessary. The combination of yin and yang is the real forest of all things."

"Then, it's the tailed beast chakra and immortal arts."

As a man who knows the original work well, Uchiha Yu is thinking about it in his mind and quickly integrates these aspects that can be improved in the future.

Among them, the improvement of Uchiha bloodline can be arranged.

The Sharingan upgrade will further awaken the blood limit in his body, making the cells in his body produce more and stronger chakra.

As for the power of Ashura and Indra in Hashirama Senju and Madara Uchiha, Uchiha Yu is not going to do anything for the time being.

The water of Naruto is too deep, and he is too weak now. Even if he has a cheat, he can't be too reckless.

Because once someone wants to mess with you, no matter how powerful they are, they will have a way to deal with you.

Moreover, there is not only Otsutsuki Agarwood in Madara's body, but also Otsutsuki Hagoromo in the underworld observing the changes in the ninja world.

Even Uchiha Yu suspected that Otsutsuki Hagoromo was not simply old and dead, but after his body was old, he went to the underworld to arrange some hidden hands.

Before he understood the intentions of the Six Paths Sage, or had the ability to compete with the Six Paths Sage, he did not plan to attack Hashirama Senju and Madara Uchiha.

As for the tailed beasts.

Uchiha Yu might do some research, but as for sealing it in his body to become a Jinchūriki, Uchiha Yu has no intention of self-harming for the time being.

Although the energy of the tailed beast is magnificent, it is also violent and complex, and full of corrosive and negative energy. Before he has developed the power to completely devour the power of the tailed beast for his own use, Uchiha Yu does not intend to attack the tailed beast.

Finally, it is the magic.

Uchiha Yu first thought of the three holy places, but he quickly rejected this idea.

The waters of the three holy places are also very deep, and they are even the indigenous forces of this planet.

Moreover, although the magic of the three holy places has its own characteristics, it is not the perfect magic in Uchiha Yu's mind.

Because in Uchiha Yu's cognition, these so-called three holy places do not have the qualifications at all.He wanted to become a real immortal, a kind of acquired practice, to reach an existence comparable to or even beyond the gods. However, these were too far away for Uchiha Yu. However, he had some ideas about the immortal chakra. After breaking through the level, the chakra refining technique became the chakra refining technique. With the practice of chakra refining technique, he controlled his body and energy, and he occasionally felt some special forces flowing around him. These forces, especially after the completion of the multiple crow shadow clone technique, became clearer. Especially every time he breathed, the special operation brought by the living body technique in his body seemed to be able to absorb the external forces as nutrients. The amount absorbed was not much. Compared with the energy he breathed into his body, the digested energy may be less than one thousandth of the energy he breathed into his body. However, after the appearance of the crow shadow clone, he felt that the efficiency of absorption could reach one percent, and the changes in his body became more and more obvious. After this power was absorbed, it seemed that it could directly strengthen his own chakra. Or, it was absorbed as nutrients and converted into chakra energy.

Uchiha Yu was sure that this energy was not extracted from cells, but simply absorbed nutrients from the world through breathing and converted into chakra energy.

This energy was abundant, rich, and powerful, and it continuously improved the attribute power in Uchiha Yu's body, making the five attribute strengths in Uchiha Yu's body quietly strengthened at a perceptible speed.

There were even two other attributes, one that made the body extremely comfortable and relaxed, and the other that made the eyes eager to move.

The increase of the two energies quietly increased the upper limit of Uchiha Yu's chakra in silence.

If Uchiha Yu guessed correctly, the last two attributes should be yin and yang attributes.

However, what Uchiha Yu was more concerned about was why such a phenomenon occurred.

The celestial arts in Naruto only re-proportion chakra and natural energy into a new power;

But when he breathes in and out, he instinctively absorbs and transforms natural energy into chakra, and can also strengthen his own attribute strength.

This is an extraordinary discovery.

Perhaps Uchiha Yu cannot get the blessing of the sage mode.

However, Uchiha Yu feels that understanding this path may be more valuable than the sage mode.
