Ninja World: I fought the five Kages hard, and then the system came

The underworld has a natural suppressive force on the souls of the dead.

Even a powerful person like Yuyi Xuanyue could not resist the power of the underworld.

If I had not been cautious and my soul had not completely separated from my body in the first attempt, I would never be able to stand here so easily.

"When my soul is half separated, I can only barely keep steady when facing the suction of the underworld. If my soul is completely out of my body, I will definitely not be able to move. Not to mention merging with my real body, I am afraid that I will be pulled up by the power of the underworld as soon as I take a step."

Yuyi Xuanyue touched his chin, looked up at the clear and cloudless sky, and thought.

I must find a way to resist the attraction of the underworld, or strengthen the soul itself.

"Soul."

Yuyi Xuanyue frowned.

There are thousands of ninjutsu in the world, but there are very few secret techniques related to the soul.

There is no way, because the soul is too mysterious.

When I was alive, I focused more on chakra analysis, and I always took a cautious attitude towards the soul.

He couldn't be like Orochimaru who didn't take others seriously, let alone himself.

He tossed his soul into pieces and it was unrecognizable, but he didn't die. He could only say that he was too lucky.

Yuyi Xuanyue didn't study the soul deeply.

He tried the few soul secrets he mastered during his lifetime, but the effect was not very good.

He looked up at the crack of the underworld above again, and Yuyi Xuanyue's soul skillfully returned to the dirty earth body and shook his head:

"It still doesn't work. The resistance of the underworld is too foul, and the boundary between life and death is not so easy to break."

The Samsara Eye can succeed because its own quality is too high.

Just like the Ten Tails, Kaguya Otsutsuki and other aliens.

As the strongest support of the Otsutsuki clan, the overlord of the universe, the magic of the Samsara Eye is far more than resurrection.

"Unfortunately, I am not the reincarnation of Ashura or Indra's chakra. Even if I get the flesh and blood of the two, I can't evolve the Samsara Eye."

Except for the Otsutsuki clan with pure blood.

In the entire ninja world, only the reincarnation of Indra's chakra can open the Samsara Eye by transplanting the flesh or cells of the reincarnation of Ashura's chakra.

For example, Uchiha and Senju people have children, and Uchiha transplants Hashirama's cells, it is impossible to give birth to the Samsara Eye. At most, they can develop the power of Wood Release like Obito.

The Samsara Eye is too far away, so let's put it aside for now.

After continuous attempts, the sky has darkened at this time, and the temperature has dropped by ten degrees compared to the daytime.

Yuyi Xuanyue sat cross-legged without caring.

The Impure World Body has no sense of temperature, no sense of pain, no fatigue, no need to eat, and no need to relieve oneself.

Without being delayed by trivial matters, I can think about the problems I encounter with all my heart.

"Put aside the chakra research for now, and then devote all my energy to the research on the soul?"

Yuyi Xuanyue thought about it and rejected this proposal.

Let's not talk about whether the research can succeed.

Even if it succeeds, it will take a lot of time and energy.

What he lacked the most right now was time.

Although the Impure World Body would not dissipate in ten days or half a month, the remaining time was not enough to support the research results on the soul.

You should know that Orochimaru, the most powerful scientist in the ninja world, spent at least ten years to develop the Reincarnation without Corpse.

Although Yuyi Xuanyue was very talented, he did not dare to guarantee that it would take a shorter time.

If he was really that powerful, he would have completed the research on the Bloodline Network and would have been invincible in the world, and he would not even need to think hard here.

In the current situation, he could not get through on his own. He could only rely on the outside world.

Yuyi Xuanyue never looked down on others.

Although he was called a person who was on par with gods, he was still a human being after all, and his time in life was limited.

Compared with himself, it was normal for the ninja world that had accumulated for thousands of years to have more suitable methods.

Yuyi Xuanyue thought seriously.

As he had thought before, what he needed most now was a special soul secret technique that could ignore distance and reach in an instant.

Once his soul reaches his real body and merges perfectly with it, it will be like his soul in the filthy earth body, and the underworld will no longer be able to do anything to him.

"Does the ninja world have such a soul secret technique?"

Yuyi Xuanyue carefully recalled the memories that had been buried for many years.

Suddenly!

A white and hot picture flashed through his mind.

To describe it in one word, it is "tolerance is greatness".

Tolerance is greatness is not right!

To be more precise, it is the ex-boyfriend who died early.

The man who has the dream of being a protagonist but not the fate of being a protagonist.

If I remember correctly, it seems to be called Duan.

As for the surname.

Hehe.

Yuyi Xuanyue, who had studied the works of many teachers in his previous life, was impressed by the surname "Kato".

Even after so many years, for such a minor character who appeared not long ago, because of the name "Kato", he can always remember it in his heart.

"Spiritualization Technique!"

When thinking of Kato Dan, Yuyi Xuanyue immediately thought of the ninjutsu that appeared in the Fourth War.

This S-level soul secret technique, which allows one's soul to temporarily leave the body, travel through time and kill enemies regardless of distance, and can also control the other party's body or enter the spiritual world of others, is exactly what he needs.

Yuyi Xuanyue's eyes suddenly lit up.

That's it!

He must get it!

As it concerns the resurrection plan, Yuyi Xuanyue can't wait to get up and prepare for action.

But before that, there is one more thing to confirm.

Where is the Reincarnation Technique?

Kato Dan is dead. Even if he is resurrected by the Impure World Reincarnation, he can only be forced to fight, not to let him reveal the practice method of the Reincarnation Technique.

As for the fact that you can directly learn and perform the same ninjutsu by watching the other party make a seal?

Come, I'll give you both hands.

You clap and try to see if you can summon the Buddha.

The Reincarnation Technique is judged to be S-level, not because of the effect of the technique, but because of the difficulty of learning.

It is risky for ninjas to learn ninjutsu.

The reason why forbidden techniques are called forbidden techniques is not because of their lethality. After all, a fireball can also kill people.

More importantly, it is very likely that the practitioner will hurt himself or even endanger his life during the practice.

This is exactly why Konoha set up the Sealed Book and stipulated that the techniques recorded in it cannot be spread.

Just like the Multiple Shadow Clone Technique, once a person with an average amount of chakra uses it, his chakra will be exhausted and he will die.

If there are really no restrictions and individuals are allowed to practice, more than ninety out of a hundred self-important ninjas will die.

Not every ninja is Namikaze Minato or Uzumaki Naruto.

In other words, Yuyi Xuanyue is not worried about not being able to find the spirit transformation technique.

As creatures who live on the edge of a knife and whose life and death are unpredictable, ninjas will definitely record their own ninjutsu and keep it in their families or ninja villages so that it can be passed down to avoid complete interruption.

As a Konoha ninja, Kato Dan is definitely no exception.
