My brother Uchiha Madara

Three hundred root seeds with negative power, three hundred seeds with some root attributes, three hundred seeds with various bloodline characteristics, and the last one hundred seeds were infused with Uchiha Yu's pupil power.

All the Chakra root seeds with negative power are prepared for the Uchiha clan.

This kind of root seed will be affected by negative power for a period of time after use, making emotions extremely unbalanced and increasing the probability of opening the eyes.

Among the Uchiha, there are many ninjas who are strong but cannot open their eyes due to their own bloodline qualifications.

These ninjas are treasures.

Chakra root seeds are the easiest for this type of Uchiha to accept, and the improvement is the most obvious;

And with the stimulation of negative power, once the eyes are opened, their combat power will show a blowout improvement, and even their combat power can directly threaten Uchiha Tajima.

Because this type of people have a low dependence on the Sharingan, they will have more ways to deal with the suppression of high-level Sharingan.

Although such an increase is useless in fighting against Hashirama Senju, it is catastrophic to other Senju.

Even if Tobirama Senju is not injured and has learned Flying Thunder God and a group of ninjutsu, he still has to be careful when facing such a group of Uchiha.

If he is not careful, he may be killed there.

This is the Uchiha, a race where 1 plus 1 is greater than 2 in regular group battles.

The more people there are, the more desperate the opponent will be.

.....

The second type of chakra root seed is the root seed that integrates the root attribute.

Each root attribute can refine and improve a certain attribute of a ninja.

Although it cannot reach the root level, the power of ninjutsu can be greatly increased.

The root seed of bloodline power is similar to the attribute root seed, but it can strengthen two attributes at the same time and maintain those two attributes in a special ratio.

Although it is impossible to directly develop a new bloodline like Bai Lian, it can allow a ninja to use a combination of ninjutsu to achieve a similar effect to bloodline.

For example, Feng Shui combined ninjutsu may be able to form a "cold wind" type of ninjutsu, but it is difficult to form an ice escape effect.

However, using the chakra root seeds of ice escape can improve the two attributes of Feng Shui to a certain degree and a certain ratio, so that the ninja does not need to deliberately control it, and can complete the use of ice escape through the combination of ninjutsu between Feng Shui.

To a certain extent, this is a seal-type bloodline ninjutsu that cannot be passed down.

There are three hundred bloodline chakra root seeds, including ice escape, melting escape, boiling escape, sand escape, and burning escape. In order to cater to the attributes of Uchiha's fire escape, the burning escape is given the most.

At this time, he didn't believe anyone who said that Uchiha's fire could not burn people.

And the last one hundred root seeds were condensed by Uchiha Yu specifically for Uchiha Madara.

Each of them has been integrated with part of Uchiha Yu's pupil power. The most important thing is that he has used the repair technique to infuse life energy and written the passive skill of the gaze technique.

The pupil power carried by a chakra root seed is not very strong, but it will continue to act on Madara's eyes, forming a continuous effect.

It can repair eye damage to a certain extent and relieve eye fatigue caused by the activation of pupil power.

100 chakra root seeds may not bring too much improvement to Uchiha Madara, but it can reduce the damage he suffers from opening the Mangekyō 100 times by at least 10 times.

And this is also an attempt.

He wants to let his power compete with the Otsutsuki Agarwood in Uchiha Madara's body, or even the power of Indra.

He even wants to try to touch the Six Paths Sage.

And the bet this time is Uchiha Madara's eyes.

Anyway, Uchiha Madara's eyes will go blind in the future, and they will be replaced by Uchiha Izuna's eyes. These eyes are useless, so it's okay to keep them as a collection.

Always taking the Six Paths Sage as an imaginary enemy, without testing the other party's depth and attitude, Uchiha Yu always feels a little uneasy.

This is not Uchiha Yu's impulsive behavior, but with the increase of his own root attributes and the improvement of the Chakra Root Technique, he feels that he is closer to the source of negative emotions.

And the closer he is, the more panic he feels.

The closer he is, the more he has a strong intuition.

The road is wrong.

He has always been a wretched development, and he is determined not to stand on the opposite side of the masses. He would rather be a fish struggling freely in the river than a barrier stone that resists the great torrent.

However, since he absorbed the ominous power in his body, he felt that he was going against his original intention.

Originally wanted to talk about other things after completing the chakra root technique, but at this moment, he was at the source of the underground veins of the Wind Country, but that idea gradually changed.

At this moment, Uchiha Yu was in an underground mine.

Here, there were stones full of rich natural energy, like the spiritual stones in the immortal novels.

The Stone of Garel.

Uchiha Yu remembered that this seemed to be a special energy stone in the Naruto movie, which was once used by a ninja clan to develop some energy props.

Uchiha Yu pried off an energy stone casually, and the moment he got it, he felt his chakra surge, giving him an impatient feeling.

A feeling of wanting to devour it impatiently.

It seemed to be an instinct.

Uchiha Yu did not restrain this impulse and tried to do so.

The result was very surprising.

One, just one energy stone, increased Uchiha Yu's energy limit by half a card.

And here, there are tens of thousands of energy stones, at least millions according to Uchiha Yu's detection.

With Uchiha Yu's chakra-transformed body, he has already broken the shackles of flesh and blood, and can devour these natural energies without limit, turning them into the root chakra of his own brand.

One million energy stones means an increase of 500,000 cards.

What is the concept of 500,000 cards?

According to Uchiha Yu's measurement of Senju Hashirama's chakra, his advanced sage body can only break through the 10,000 card state at most, practice the sage mode, and reach a maximum increase of 10 times, exerting about 100,000 cards of power.

Taking Kakashi as the standard, it may not be in line with it.

However, taking Senju Hashirama as the basic unit, it is very stable.

After devouring and absorbing these energy stones, he is almost equivalent to 5 peak-stage Senju Hashirama.

And now Senju Hashirama is just adapting to the sage mode, and is far from reaching the strength of 10 times the increase.

This discovery is undoubtedly exciting for Uchiha Yu.

As long as he absorbs these, he can beat Senju Hashirama into autism.

So, he decisively began to absorb.

However, with the continuous crazy transformation and rapid improvement, Uchiha Yu also had a clearer perception of the changes in his body.

He found that the negative power in his body was increasing at a speed visible to the naked eye as the chakra continued to increase.

At that moment, Uchiha Yu suddenly realized the possible origin of his negative power.

"Is the transformation of natural energy the root of the existence of negative power?"
