Escape from Konoha.

Liuli had some knowledge of the Book of Sealing, but she wasn't particularly clear about how many forbidden techniques, profound arts, and secret skills were recorded in it, or what their types were.

How about choosing a soul-related ninjutsu?

Shiraishi offered his suggestion.

"soul?"

Liuli raised an eyebrow.

"I heard there's a Jonin in the village named Kato Dan who knows a very mysterious soul-type ninjutsu. He's also supposedly Tsunade's boyfriend. I think this type of ninjutsu would be very helpful for my research."

"understood."

After thinking for a moment, Liuli nodded in agreement.

In any case, she doesn't have much need for the ninjutsu in the Book of Seals. If the soul-type ninjutsu can really help Shiraishi and help him unlock the secrets of Sage Mode sooner, it would be a huge boost for her.

Chapter 47 The Shura Field Does Not Exist

It didn't take Ruri long to go to the Hokage Building and return home.

When he returned, Shiraishi saw that Ruri was holding a scroll and casually tossed it to him.

Thanks.

Bai Shi didn't stand on ceremony and simply accepted the scroll.

"You just need to hurry up and figure out the magic."

"This is quite difficult, after all, there is a severe lack of information on immortal techniques. Even just learning from them would be helpful. If we could study the immortal techniques systems of the three holy lands, it would undoubtedly be of great assistance to my work."

"Give up. If it weren't for the spiritual contracts signed with the three holy lands, it would be difficult to find that place, let alone obtain immortal techniques from it."

"So, the Sannin really are blessed with extraordinary talent."

The rumors that the Legendary Sannin of Konoha had close ties with the three great holy lands have been circulating for a long time.

Not only are they disciples of the Hokage, but they also have the support of the three great holy lands, something that ordinary ninjas can only dream of for a lifetime.

"But even among the Three Ninja, I've never heard of them successfully mastering Sage Mode."

"Of course, I don't know if there's any difference between the Sage Techniques that summoned beasts practice and the Sage Techniques I'm researching, but fusing natural energy with ordinary chakra does indeed carry a considerable risk; it could really kill someone."

Shiraishi sat down in the room, took a sip of tea, and then unrolled the scroll in his hand.

The scroll begins by recording the developer and name of the ninjutsu.

The art of spiritualization.

The developer is Tobirama Senju, the previous Hokage.

According to records, the art of spirit transformation is a technique that allows the soul to leave the body and travel regardless of distance, directly killing enemies.

However, even after the soul leaves the body, the spirit retains the caster's consciousness. Therefore, this ninjutsu has a wide range of uses, not only in combat, but also for transmitting information, sensing over a wide area, and even transferring chakra to comrades. The Spirit Transformation Technique can accomplish all of these.

It must be said that Tobirama Senju, the Hokage who developed this ninjutsu, was a respectable figure.

I heard he sacrificed himself on the battlefield of the First Shinobi World War, which is a pity.

Shiraishi strongly agreed with many of the ideas of the previous Hokage.

He built ninja schools, established the Anbu organization, divided and suppressed ninja clans, improved the status of commoners, and created various secret techniques and ninjutsu belonging to the Konoha school... His influence can be seen in the political, scientific, and military fields, and he was the one who created them, which were then imitated by ninja villages around the world.

The era of one village per country was created by the Senju and Uchiha clans, but this system was merely a name without substance. If it weren't for the previous Hokage, Tobirama Senju, the so-called ninja village... if you think about it carefully, it would be no different from the chaotic situation of ninja clans dividing up the country during the Warring States period.

It wasn't until the previous Hokage took office and implemented a series of groundbreaking reforms that this distorted system of ninja clans ruling the village gradually began to improve. The common people were used to check the ninja clans, and from then on, a stable balance was formed among the various factions in Konoha, with each faction checking and supporting the other.

Their balancing skills are truly admirable.

The only pity is that there was no follow-up.

With the outbreak of the First Shinobi World War, the previous Hokage, Tobirama Senju, passed away. Even though he still had unfulfilled ambitions and ideals in his heart, he could only let them go with the wind, entrusting the future of the village to the current Third Hokage.

As for the Third Hokage, Shiraishi doesn't know much about him, perhaps because the achievements of the previous Hokage have overshadowed his accomplishments.

After all, many systems were already perfected during the time of the previous Hokage, which meant that no matter how great the successors were, they could not surpass their predecessors. So, we can only look forward to what amazing things the Third Hokage will do in the future.

After thinking all this through, Shiraishi took the scroll of the Spirit Transformation Technique and returned to the underground laboratory.

He has already infused natural energy into the experimental subject and needs some time to observe and collect data.

So, it's time to consider the issue of the 'Caged Bird' seal.

Shiraishi had actually been researching the Caged Bird for some time, but due to a lack of data and the fact that the deeper structure of chakra had not yet been fully analyzed, progress in this area had stalled for a long time.

According to Ayane, once a caged bird is marked, it will follow it for life and will only be removed upon death.

In other words, the caged bird can be released by the condition of 'death'.

So, what kind of state is 'death'?

Body or soul?

What characteristics are attributed to chakra in this context?

Humans are born with chakra, and they die when they lose it.

If Ayane were to die from chakra exhaustion, would the Caged Bird Seal be removed?

Of course, this kind of death is not real death, but a state of suspended animation similar to death.

Then, he repeatedly gave Ayane chakra to wake her up from her suspended animation.

The premise for conducting this experiment is to first verify a viewpoint.

That is, after a person loses chakra... will they really die?

If losing chakra doesn't necessarily mean death, then... where does chakra come from?

Why has it become the energy source for life activities essential for human survival?

Is death due to the loss of chakra considered physical death or spiritual death?

Is it possible for a human to enter a strange state of suspended animation after losing chakra, and then be brought back to life after being given chakra again? Is such a thing even possible?

If all of these can be confirmed through experiments, then eliminating caged birds may no longer be a difficult problem.

It also resolved many of Shiraishi's doubts.

Shiraishi carefully recorded these guesses in the notebook he always carried with him.

In science, you first have questions before you can speculate, and then you have to prove whether something is right or wrong.

Therefore, the research on soul ninjutsu is very necessary.

The only troublesome thing is that we are in a time of war, and he may have to go out on missions at any time, which means he will not have time to conduct experiments here.

Listening to the eerie screams coming from the experimental subject on the operating table, the pain was unbearable. They wanted to scream but couldn't make a sound. They felt like their throats were about to burst, but they could only hear the faint sounds of themselves struggling on the operating table.

Shiraishi calmly watched the experimental subject convulsing on the operating table, his face contorted in pain. His eyes were devoid of emotion as he skillfully cut a piece of skin eroded by natural energy from the subject's arm. The skin was a pale green color. He placed it in a container and examined it under a microscope.

Next, he looked at the computer screen, which displayed the heart rate of the test subject on the operating table and the fluctuation value generated by the fusion of natural energy and chakra.

These experimental subjects went from being uncooperative at the beginning to being manipulated and reduced to numb dolls, their eyes devoid of even the emotion of fear.

Shiraishi admitted that this was a miscalculation.

Unexpectedly, the fusion of natural energy with chakra within the human body would cause such a terrifying mental and physical impact on the individual.

Therefore, whenever a test subject shows signs of mental breakdown, the experiment is stopped immediately, a sedative is prescribed, and another test subject is brought in.

This kind of repeated and sustainable use can also save costs.

Shiraishi looked at the other people trembling by the wall and shook his head. Honestly, these guys have no spirit of dedication to science whatsoever.

If his experiment succeeds, these people can instantly transform from ordinary people into ordinary people whose bodies are filled with Sage Chakra. Although they will not know any ninjutsu, their vitality, strength, speed, and reaction speed will all be qualitatively improved.

I can't speak for other things, but living to be a hundred years old should be no problem.

As for immortality... Bai Shi thought about it helplessly, realizing that his thoughts were becoming increasingly absurd.

"The research on natural energy is basically complete. Sage Chakra still needs further data analysis to improve the fusion success rate. Next, we can focus on dealing with the Caged Bird Seal issue..."

Um?and many more!

Shiraishi suddenly realized a very serious problem: how could he collect detailed physical data about Ayane's current state?

He is currently residing in the Uchiha clan's territory, while Ayane is a ninja from the Hyuga clan.

If we bring Ayane here, and Ruri happens to find out...

A bead of cold sweat involuntarily trickled down Shiraishi's face.

Quickly calculate your chances of survival if you are discovered.

Chapter Forty-Eight: Longing is the emotion furthest from understanding.

It was an hour later when I arrived at Liuli's room.

The other person was holding a scroll and studying something carefully. Shiraishi glanced at it and saw that the contents recorded on it were related to fire-style ninjutsu.

"what's up?"

Liuli looked up from the scroll and glanced at Baishi.

"Oh, um... I want to go to the pharmacy to buy some herbs; we don't have enough in the lab."

Shiraishi scratched his head, his expression unchanged, showing no sign of anything unusual.

"Okay, remember to bring me some natto when you come back."

"Natto?"

Shiraishi nodded to indicate that he understood, and then left the room.

Once outside, I breathed a sigh of relief; I had finally gotten through it.

Bringing Ayane here to collect her body data is highly improbable and difficult to accomplish; the probability of her being discovered by accident is far too high.

This is the heartland of the Uchiha clan; even with the Byakugan, one cannot easily infiltrate here.

Otherwise, the Uchiha clan wouldn't have such a great reputation in the ninja world.
