Naruto: If I ask you to practice gentle fist, will you drive a Gundam?

Late at night, Neji woke up as usual.

Ever since he combined the complete Nine-Tails and Otsutsuki bloodline, his body has too much chakra, so he would always be woken up by the chakra when he sleeps at night.

"Huh, it's this feeling again. It's quite troublesome."

Thinking that he would be able to synthesize more Nine-Tails and Otsutsuki essence soon, Neji wondered if it would be more difficult to fall asleep after the synthesis, or was this situation caused by the insufficient awakening of the Otsutsuki bloodline?

At this time, Neji casually put on a piece of clothing and walked to the indoor training ground in the branch family's territory as usual.

Whenever Neji couldn't sleep at night, he would come here alone to consume some chakra, and then go back to sleep.

The ability that Neji has mastered that consumes the most chakra is definitely the Mangekyō Sharingan.

Ningci moved his mind and opened the system space.

Four years have passed since the Uchiha clan genocide. During these four years, Ningji has stockpiled a large number of Sharingans.

Uchiha Obito and Uchiha Itachi each have stockpiled around 16,000 Mangekyō Sharingan.

Ningji originally wanted to take out 2 of each to add up to to exchange for the Eternal Mangekyo Eye Blind Box.

But Neji was afraid that the blind box he opened would be a garbage ability.

Because in the original work, although only Madara and Sasuke can open the Eternal Mangekyō, that only means that the conditions for opening it have been met, which does not mean that other people's Mangekyō cannot evolve.

In other words, these 2 eyes can be exchanged for Madara or Sasuke's Eternal Mangekyō, or for other unknown Eternal Mangekyō, such as those of Uchiha's side branches.

If all these years of hoarding result in a rubbish eye, it would be better not to exchange it.

Moreover, Neji learned that if he could collect 2 of the same kind of Mangekyō Sharingan, it could directly evolve into the Eternal Mangekyō.

In the original work, it is Itachi and Obito's Mangekyō. It is already very abnormal without the eternal mode. If they can turn on the eternal Mangekyō, wouldn't they be invincible?

Itachi's abilities are the red Susanoo and the Totsuka sword, while Obito's ability is Kamui. It seems that he cannot activate Susanoo, but that should be because Kishimoto considered that Obito's ability itself was too buggy so he didn't write it.

After all, whether it is the number of times the Sharingan has been used, the proficiency, or the amount of chakra, Obito has all the conditions to open Susanoo. It is not because he needs two eyes to open it. In the original work, Shisui opened Susanoo with just one eye.

Therefore, it can only be a problem with the setting of the original work.

Thinking of this, Neji suddenly had an idea. Since Obito had never opened Susanoo before, what would it be like if I opened Susanoo with his eyes one day to show him?

It must be very exciting.

Moreover, there are actually quite a few Mangekyō Sharingan within the Uchiha family, but very few of them are portrayed in detail, and only the main characters can activate Susanoo.

In theory, as long as one has the Mangekyō Sharingan and the pupil power is strong enough, one can open it.

Then let me, Hyuga Neji, fulfill the regret of the Uchiha family!

Thinking of this, Neji couldn't help but look forward to the future.

But right now I need to quickly consume some chakra and go back to sleep.

"Kagura Heart Eye!"

According to Neji's perception, the chakras of all the people in the branch family's land were displayed in Neji's consciousness space. Seeing that the chakras were still familiar and they were all sleeping in their respective rooms, far away from the training ground, Neji felt relieved.

Then, Neji replaced Itachi's Mangekyō with his left eye and Obito's Mangekyō with his right eye, and began training at the wooden stakes on the training ground.

"Amaterasu!"

With a "Cing!" sound, a ball of black flame ignited on the wooden figure.

"Divine power!"

The next second, the wooden man disappeared, and a ball of fire was burning out of thin air.

"It is indeed a black flame that will not go out. It seems that Amaterasu's burning does not rely on combustible gas or some fuel."

Having received higher education in his previous life, Neji naturally came to this conclusion.

"Divine power!"

Suddenly, Ningji brought out the milk tea in the Tun Tun Rat space and transferred Amaterasu into the milk tea, but found that the fire was still burning.

In this regard, Ningji had a bold idea.

The eternal flame, doesn't that mean endless energy?

If it can be used reasonably, it will be better than any new energy source.

What does endless energy mean? This question may be a bit difficult for the natives of the Naruto world.

But Neji understood that endless energy meant perpetual motion machine, which meant an inexhaustible source of energy. Moreover, with the Mangekyō Sharingan, he could turn Amaterasu on and off at will, which was more convenient and safer than nuclear energy.

After a while, the milk tea was burned out, even the liquid in it was burned dry.

Seeing that the black flames were about to burn to the floor, Neji used the Mangekyō to shut down Amaterasu.

When I opened my left eye again, I felt that one third of it had turned black. It was no wonder. After all, I had been using this eye to practice pupil techniques these days, so the speed of blindness had greatly accelerated.

Suddenly, Ningci had an idea. Can he use the broken Sharingan to redeem the blind box? It would be great if it is possible.

The system sensed Ningci's doubts and provided an answer again:

[Sharingan is Sharingan, any state can be exchanged for a higher eye blind box! 】

That means it's okay.

After receiving a positive response from the system, Neji began to use the Sharingan even more unscrupulously.

"Divine power!"

"Amaterasu!"

"Divine power!"

. . .

Neji used various methods to control the two Sharingan and played with Kamui and Amaterasu in various ways.

Not only that, but Neji also uses Tsukuyomi on himself through the mirror.

After using it, he found that the mental damage caused by Tsukuyomi can be adjusted.

Through this method, Neji can not only improve the power and proficiency of his Mangekyō Sharingan, but also quickly improve his resistance to illusions.

Because he didn't have to worry about going blind and could turn the Mangekyō on and off at will, Neji boldly tried various ways of using the Sharingan, and one fantastic idea after another was born in his mind.

Compared with this feeling of high mental excitement, the pain of blood and tears shed when using the kaleidoscope is nothing. Besides, if you lose eyes, you can replace them at will. There are more than 20,000 eyes in the warehouse.

Use it! Use it as you like!

After tossing and turning for two or three hours with his Mangekyō Sharingan fully open, Neji felt that about 10% of the chakra in his body had finally been consumed, and the bloating feeling in his abdomen had also subsided a little.

"Phew, that's it for today!"

Cing!

Neji used the Mangekyō to extinguish all the black flames inside the room, wiped the blood from the corners of his eyes, washed his face, and walked back to his room to rest contentedly.
