Analyzing the Ninja World Starting from Konoha

"Can it change the future...?"

Kato Dan murmured softly.

Isn't this exactly what he once dreamed of?

Become Hokage, protect the village, and protect the people who are important to you.

Kato Dan looked at the boy in front of him and remained silent for a long time.

He looked at the young man in front of him and saw in him a maturity and persistence beyond his years.

Although he is dead, his will may continue through this boy.

"Okay, I'll teach you."

He looked at Qingye, his tone solemn.

He could sense that Aoba was still holding back.

However, he did not see greed or ambition in the other person's eyes; at least he could sense that Qingye was not an evil person.

Of course, more importantly, he trusted Tsunade and Jiraiya's judgment.

Aoba breathed a sigh of relief.

It's finally done.

"However, I must remind you."

Kato Dan continued, "The art of spiritualization is a secret technique of our Kato clan. It has special requirements for talent; it requires the practitioner to achieve a special synchronization between the mind and soul. Even within our main family, there have been very few people who have mastered it over the centuries."

"It's okay, I still have some confidence in my talent."

Aoba smiled confidently.

In his view, there is no skill that cannot be mastered; so-called "special talents" are more like incomplete skills.

And this is precisely what chips excel at.

"it is good."

Kato said no more.

He began to explain in detail the principles and hand seals of the [Spiritualization Technique].

"The core of the art of spiritualization lies in separating spiritual energy from physical energy and maintaining the stability of the spiritual body..."

"The sequence of hand seals is: Yin – Si – Zi – Chen – Wei..."

Aoba's expression was focused, while the chip in his mind was operating at an alarming speed, perfectly recording, modeling, and storing every syllable, every gesture, and every flow of chakra.

[High-level ninjutsu data stream detected...]

[Entering data...]

[Building a model...]

[Analysis of the Spirit Transformation Technique in progress...]

A large amount of obscure and difficult knowledge was disassembled and reassembled by the chip, and transformed into data that Aoba could understand.

Kato Dan explained it in great detail, including not only the technique itself, but also his insights from years of practice, as well as the techniques for using spiritualization in actual combat.

This is priceless.

More than an hour later, Kato Dan finally stopped.

"That's all there is to the art of spiritification."

Kato Dan looked at Aoba. "Can you remember it?"

"Yes, I've remembered them all."

Aoba said sincerely, "Thank you, Senior Dan."

"You're welcome."

Duan looked at the sky gradually darkening outside the cave, his expression complex.

"If you really can change the future... please take good care of Tsunade for me."

"I will."

Aoba solemnly promises.

"Furthermore, I will not break the contract of Edo Tensei."

"I will not undo the Impure World Reincarnation."

Kato Dan was taken aback: "What do you mean?"

"I will seal you away temporarily."

Aoba explained, "I'm not sure if I can really change the future. Some things may be destined. If it's really as I suspect, I hope you can persuade Tsunade-sensei to take over the Hokage position ahead of schedule."

"Shall we see Tsunade?"

Kato Dan's body jolted, and his eyes flashed with astonishing light: "Really... is it possible?"

"sure."

Aoba nodded. "If the timing weren't so bad, I would have liked to bring Tsunade-sensei to see you."

"After all, that's your dream too, isn't it?"

Become Hokage and protect the village.

That was his obsession during his lifetime, and also the promise he made to Tsunade.

Kato Dan remained silent for a long time before finally revealing a relieved smile.

"it is good."

A long-lost smile appeared on Duan's face, a smile of relief and anticipation.

"I'm waiting for you."

"Thank you, Aoba."

Aoba nodded, clasped his hands together, and a wooden coffin appeared out of thin air, resealing the Edo Tensei.

Then he waved his hand, and the gourd on his back turned into a stream of sand, erasing all traces in the cave.

After doing all this, Aoba checked the surroundings to make sure that no trace of chakra was left behind.

"withdraw."

The sand cushion lifted his body, and he flew low, skimming the treetops, quickly disappearing into the morning mist.

……

When they returned to Konoha, it was just dawn.

Aoba skillfully slipped through the gap in the barrier and returned to her room.

The shadow clone was still lying in bed pretending to be asleep.

With a "bang," the shadow clone was dispelled.

Memories flooded my mind.

Nothing happened that night.

Young people are at the peak of their energy.

Aoba lay in bed, unable to sleep, so she decided to review the events of the previous night.

As he suspected, this Impure World Reincarnation was indeed the original version, without even any talisman control, relying entirely on the caster's suppression.

Furthermore, the strength of the reanimated dead is very low. Although the sacrifices he used are a factor, his strength is indeed weak. No wonder the Second Hokage needed to use the reanimated dead in conjunction with the Mutual Multiplication Explosive Tags.

Fortunately, the established goal was achieved.

Spiritualization Technique!

It can materialize spiritual energy, kill enemies regardless of distance, and even control their bodies.

It can be described as the ninja world version of astral projection.

The connecting seals also differ from the regular twelve seals.

Since she couldn't sleep anyway, Aoba simply got up and sat cross-legged on the bed.

He began to recall the hand seals for the Spirit Transformation Technique.

He then began to try forming hand seals and mobilizing the chakra within his body.

However, nothing happened.

The chakra circulated throughout the body before finally returning to calm.

It didn't work as expected.

Aoba was not surprised.

As a forbidden technique, the [Spirit Transformation Technique] is far more difficult than the Impure World Technique.

Impure World is more like another form of summoning magic. With a foundation in summoning magic, it's relatively easy to learn. The Spirit Transformation Technique, however, is quite different. It involves soul techniques and is relatively unique. The meaning of many incantations in the technique is unknown.

Although Senior Duan said that the [Spirit Transformation Technique] was a family secret technique, Aoba's analysis showed that some of the techniques in [Impure World Reincarnation] were similar to those in the Spirit Transformation Technique.

He didn't believe that the Second Hokage didn't refer to the techniques of spirit transformation when researching the Impure World.

Even Tobirama's acquisition of the Spirit Transformation Technique wasn't necessarily honorable.

Tsk tsk tsk!

Aoba tried again, but there was still no response.

"System, retrieve ninjutsu data."

Blue light cascades across the retina like a waterfall.

"So-called special talent, huh... I see. This makes things a little more interesting."

A hint of excitement appeared on Qingye's face, the kind of novelty that only top students experience when they encounter special problems.

After several attempts, he came to the conclusion that the so-called "special talent" was more like a system incompatibility.

The system is incompatible, so Aoba can't open the new software. Therefore, he either needs to change the software's runtime code to make it compatible with the system, or build a virtual machine to create a new environment to adapt to the new software.

The main problem now is that there is too little reference material available. He dares not experiment on his own body, but relying solely on system simulation would take too long.

"It seems we need to let Senior Duan get out and about more; keeping him sealed away all the time isn't really appropriate."

Indeed, as long as you don't give up, there are always more solutions than problems.
