Analyzing the Ninja World Starting from Konoha

"It's true."

Aoba's secret passage.

Even if it wasn't Shisui, Aoba would still believe it.

The Uchiha clan's arrogance made them disdain faking such matters.

Even the Second Hokage, who was prejudiced against the Uchiha, commented that "the Uchiha's pride cannot tolerate bias," so the Uchiha have their own pride and disdain to lie.

After the Senju clan retired, the Uchiha clan could almost be considered the undisputed number one powerhouse.

The Uchiha clan is indeed full of talented people; otherwise, where would they get so many Jonin?

Compared to Shisui and Itachi, the others are not as outstanding; those two are indeed relatively more outstanding.

Instantly stop the water...

They've already started to show their talent!

That future genius who is said to possess the strongest illusion technique, "Kotoamatsukami".

That little devil from the forest back then.

Time flies!

late at night.

A small courtyard in a mountain town.

Aoba quietly reopened the barrier.

Even the Hokage wouldn't be carrying a crystal ball around looking around at this hour.

Even if she were to be checked on, Aoba had already come up with a reason.

Then a large amount of sand covered the entire room.

Double insurance: Aoba's sand itself has sealing nodes, so even the Byakugan can't see through it.

To this end, Aoba even tried to cover people's eyes with sand when one of the Hyuga branch family members went to the hospital for treatment.

Snapped!

Aoba clasped her hands together in prayer.

"Spiritual Communication - Impure World Reincarnation".

A wooden coffin slowly rose from the ground.

The coffin lid was opened, revealing Kato Dan inside, dressed in a Konoha Jonin vest.

Good evening, Senior Duan.

Aoba greeted him.

"Aoba-kun".

Kato Dan stepped out of the coffin and stretched his stiff body, though he felt nothing; it was more like a subconscious human action.

The cracks on his body became more numerous and deeper.

The two had noticed this situation as early as the third time they were summoned, but neither of them cared.

One group believes that once the durability is used up, they can simply use the spirit medium again; the other group believes that every trip back to the mortal world is a bonus.

"You're calling me so late, is there some progress in things?"

After spending this time together, the two had become quite familiar with each other, and he was also stunned into silence by the boy's whimsical ideas.

While most people are pursuing ways to increase the power of ninjutsu and perform it more covertly and unexpectedly, this guy is actually studying the structure of ninjutsu.

Just like when people buy clothes, they consider how to wear them and how to style them to look good.

Aoba was different; he was studying how the stitches were sewn on, what techniques were used, and what kind of fabric it was.

Duan never expected that ninjutsu could be learned in this way, which gave him a deeper understanding of his family's secret technique, the Spirit Transformation Technique.

If someone like Aoba had analyzed the [Spirit Transformation Technique] during his lifetime, he could very well have filled in the gaps in the spiritual transformation process.

"I have a new idea regarding the art of spiritification."

Aoba revealed his own idea, stating that the chip analysis and deduction yielded an 80% success rate.

"Separating spiritual energy from physical energy... this process isn't instantaneous, but can be done step by step. Everyone's constitution is different; perhaps ninjutsu is performed from the inside out, so perhaps we can try external intervention!"

"External intervention?"

Duan was somewhat confused and didn't understand what Qingye meant.

"Chakra is a combination of biological energy and spiritual energy. [Spiritualization] requires the stripping away of most of the biological energy, but forcibly tearing apart these two highly integrated energies causes the body to instinctively resist."

"you mean……"

"That's right, inducement."

Aoba explained, "Since spiritification can possess a target's body and control its actions, it's not advisable to perform the [Spiritification Technique] on the target's body again. Instead, the caster should guide the target's spirit to slowly leave the body. This allows the body to adapt to the state in advance. Once the body no longer rejects it, the [Spiritification] practice can be performed independently. Wouldn't this minimize the body's instinctive resistance?"

Upon hearing this, Duan fell into deep thought.

Aoba's idea completely overturned the training methods passed down through generations of the Kato clan, and even other ninjutsu.

But upon closer examination, he realized that this method was highly feasible.

"This... might actually be feasible."

"Of course, the theory is perfect, all that's missing is the practice."

Aoba smiled confidently.

"but……"

Duan hesitated somewhat because this method required extreme trust between the two parties. If the caster had any malicious intent, the life of the manipulated person would be almost entirely in the caster's hands.

"No problem, Senior Duan! I believe in you!"

Aoba could also see Duan's concerns, and gave him a thumbs up, saying, "Just like you trust me, you didn't hesitate to teach me your family's secret techniques."

Kato looked at Aoba and nodded emphatically.

Then came the trial.

Duan used the Spirit Transformation Technique again, entering Qingye's body.

Just then, a rapid alarm sounded from the chip deep within Aoba's consciousness.

[Warning! Unknown spiritual energy intrusion detected!]

Aoba was also prepared, and reliably authorized the broken spiritual energy.

Duan was also taken aback, because he encountered resistance when he first broke in, something that had never happened before.

However, after being blocked for a moment, the obstacle disappeared again.

The two met in the spiritual world and were surprised to find that Aoba-kun in the spiritual world was more mature and stable than his actual physical age.

This is a manifestation of strong mental power and one of the basic requirements for learning the art of spiritualization.

Spiritual communication is more direct than physical verbal communication, which can deceive people through body language and facial expressions, making them say things they don't mean.

However, spiritual communication won't work because it will expose one's true thoughts. This is why Obito was successfully persuaded by Naruto's talk-no-jutsu in the spiritual world during the Fourth Shinobi World War.

"Senior Duan, let's begin."

After sensing Aoba's feelings, Dan's last trace of worry completely disappeared.

He then began to control Aoba's body and cast the [Spirit Transformation Technique] again. He first connected his chakra with Aoba's chakra, and then controlled his spirit body to slowly bring Aoba's spiritual body out.

Actually, this method was something Aoba came up with based on the abilities of the Rinnegan. Since the soul can be extracted from the outside, can the spirit also be subject to external intervention?

Although the success rate of chip simulation is as high as 80%, the actual process is more difficult than imagined.

The flow of chakra needs to be extremely precise; even the slightest deviation could lead to failure.

Time passed second by second.

Sweat dripped from Qingye's forehead.

The severed spirit had already left Aoba's body, but his hands, connected to Aoba's chakra, were forcefully pulling him out.

Unfortunately, the chakra of the Impure World Body was still too low, and just when he was about to give up, he was in dire need of help.

A phantom image emerged from Qingye's body, with the spirit and the physical form forming a single superimposed image.

"It's done!"

Even though it was just a phantom, it showed that life energy and spiritual energy had separated.

Seeing this, Dan severed his chakra connection with Aoba and returned to his impure body.

Upon returning to his body, Kato Dan found dust falling from his impure body and the cracks on his body becoming more numerous.

The infinite chakra of the impure body is relative; besides the original body's strength, it depends more on the quality of the sacrifice.
