Escape from Konoha.

This means that if time continues to drag on, the ninja who casts the genjutsu will eventually run out of chakra, causing the genjutsu to be broken.

The concept that chakra cannot sustain genjutsu.

Ninjutsu and cursed seal techniques also follow this template.

Timeliness is very important.

The flames released by Fire Release techniques have a very short lifespan unless something accelerants them after they are released, allowing the flames to burn for an extended period.

Because these flames are not real flames, but are essentially a mass of chakra that has taken on the form of a 'technique'.

The curse seal cannot be maintained forever; it must have a 'time-limited' mechanism.

However, based on the observation just now, the Caged Bird Seal has a relatively obvious flaw at the moment it is activated.

Using the perception generated by the Spirit Transformation Technique, Shiraishi discovered that the special chakra produced when the Caged Bird Seal was activated was residing inside Hyuga Shingo's brain.

This chakra didn't last very long in Hyuga Shingo's brain, and it has almost disappeared on its own now.

A slight smile appeared on Shiraishi's face.

The experiment was a bit dangerous, but the results didn't seem too bad.

At the moment the Cursed Seal Technique is activated, materialized chakra is generated within the system formed by the Cursed Seal Technique.

That portion of chakra, which wasn't reclaimed by the Caged Bird Seal, was essentially depleted.

If this cycle continues, the Caged Bird Seal will eventually lose the chakra that sustains the concept of 'jutsu' and will disintegrate from within.

"The Caged Bird Seal was not fully triggered. It seems that dying by the loss of chakra is one of the ways to trigger the Caged Bird Seal."

Thinking about it this way makes things much easier.

The conditions and assumptions are all true.

He also has a complete way to replace chakra as a life energy source, which allows him to survive safely even after abandoning chakra.

Shiraishi placed his palm on Hinata Shingo's forehead to examine his brain.

This is the only slightly bad situation, and it's also the most important part of the experimental procedure.

The chakra extraction was interrupted in time, preventing the Caged Bird Seal from fully erupting, but that special chakra directly attacked Hyuga Shingo's brain nerves, causing damage.

Here's the tricky part.

If the experiment can be repeated, dissolving the Caged Bird Seal by continuously releasing chakra is not difficult. The real challenge now is to ensure the safety of the test subject's brain nerves when the Caged Bird Seal is triggered.

Shiraishi pondered for a moment, then squatted down and picked up the shards of glass from the ground.

The tool used to absorb chakra shattered, and on the glass shards, in addition to Shingo Hyuga's own chakra aura, there was another residual chakra aura.

It was the collision of two different chakras that caused the glass bottle to shatter.

"Some of them have been attracted, but the suction power doesn't seem strong enough... It seems we need to choose a tool with stronger suction power."

Shiraishi walked to the shelf next to him, picked up two chakra bottles, then took a syringe from the medicine tray and began injecting the medicine into Shingo Hyuga's body.

This is a medicine used to maintain bodily activity.

Because the upcoming experiment is even more dangerous than the one before, it is necessary to enhance Shingo Hyuga's self-recovery ability.

Otherwise, if this continues, the experimental subjects will die during the experiment before it is over.

With Shingo Hinata unconscious, Shiraishi began the second experiment.

This time, Shiraishi plans to use two chakra bottles. One chakra bottle with normal absorption power will be placed on Hyuga Shingo's chest, following the same rhythm as before. The other chakra bottle with stronger absorption power will be placed on his forehead.

If the Caged Bird Seal is triggered again and generates special chakra, try to absorb that special chakra and see if that works.

As a result, Shingo Hyuga's painful screams could be heard from time to time on the operating table.

"..."

About two hours later, seeing Hyuga Shingo on the verge of death, Shiraishi stopped the experiment.

If this continues, I feel that Shingo Hyuga will die from the pain.

Bai Shi frowned and pondered.

Through the experiments he had just conducted, he discovered that the special chakra generated when the Caged Bird Seal was activated had a very strong attachment to Hyuga Shingo's body.

Even with repeated use of chakra bottles with stronger absorption capabilities, the effect was minimal.

At this rate, even using better absorption tools will be of no use.

Shiraishi dared not make any guarantee as to whether Shingo Hyuga could continue with the experiments for the next few times.

The pain and lethality that the Caged Bird Seal caused to the human body at the moment it was triggered far exceeded Shiraishi's imagination.

"A cursed seal technique specifically developed to counter the Byakugan?"

If that's the case, it's not hard to imagine the close connection between the Caged Bird Seal and the Byakugan.

Through the experiment just now, Shiraishi has gained a certain understanding of how the Caged Bird Seal can damage the Hyuga branch family ninjas, and how to manage the risks.

"This is dragging on for too long..."

Shiraishi dared not try to kill Hyuga Shingo directly in order to conduct a more thorough observation.

This means that Shiraishi has to keep capturing Hyuga branch family ninjas. He can fool them once or twice, but after three or more times, no matter how stupid the Hyuga main family members are, they should realize that someone is targeting them.

By then, the Hyuga branch family ninjas will likely no longer leave the village to carry out missions.

Obtaining test subjects was extremely difficult at that time.

Moreover, having analyzed the matter to this point, there is no longer any need to study the bodies of the Hyuga branch family ninjas.

The connection between the Caged Bird Seal and the incomplete white eye, including its origin and how to deal with it, has been learned by Shiraishi.

Now all that's left is to observe a finished product sample.

—Hunting Hyuga main family ninjas.

Understanding the difference between the two types of Byakugan allows one to even use spiritualization techniques to possess their spiritual world, find the hidden information of the Caged Bird technique, and reverse-engineer the Caged Bird technique.

Only in this way can the experiment to break the curse of the caged bird be truly foolproof.

This matter cannot be entrusted to Ayane; I must plan the operation myself.

Compared to the branch family ninjas, the main Hyuga family ninjas rarely go out on missions, and even when they do, they are likely to be secretly protected by powerful branch family guards.

"The five of them, including Insect Man, can't possibly handle so many powerful ninjas. They might let their target escape. It seems I need to find a chance to leave the village."

Shiraishi finished his experiment on Hyuga Shingo and began thinking about how to hunt down Hyuga's main ninja.

Three days had passed, and it was afternoon.

When Konoha Jonin Shingo Hyuga went missing, the Third Hokage, Hiruzen Sarutobi, frowned upon seeing the intelligence presented by the Anbu.

According to the mission he assigned to Hyuga Shingo's team, they should have returned to Konoha yesterday morning to report on the mission at the Hokage Building.

However, more than a day has passed since yesterday morning.

According to the ANBU members operating in the Land of Fire, no trace of Shingo Hyuga's squad has been found.

Four ANBU ninjas are currently heading towards the Land of Waves to investigate the disappearance of Jonin Shingo Hyuga.

The sudden disappearance of a Jonin is no small matter for Konoha.

Fortunately, the domestic and international environment has been relatively peaceful in recent years, which has greatly reduced the workload of the Dark Guards, who no longer need to keep an eye on the Land of Fire and eliminate dangers all day long.

However, it is estimated that the Anbu will take four or five days to return and report back on their investigation in the Land of Waves.

Thinking of this, Hokage Hiruzen tapped the table, and an ANBU ninja jumped out from the shadows, awaiting orders.

"Give this to the head of the Hyuga clan."

"Yes, Hokage-sama."

The ANBU ninja took the scroll handed to him by Hiruzen and disappeared from the office.

After the ANBU ninja disappeared, Hiruzen took a deep breath.

Although it wasn't a major event concerning the village, it was only right and proper for a Jonin to communicate with the Hyuga clan promptly after losing contact without explanation, especially since he was a member of the Hyuga clan.

After all, the ninjas of this clan are somewhat special.

Let the branch family ninjas, who are restricted by the main family's Caged Bird Seal, judge for themselves whether there's anything going on inside.

As the Hokage, it's indeed difficult for him to handle these sensitive family matters.

Time passed slowly, and Hiruzen glanced at the sky outside, which had unknowingly darkened completely. He then tidied up the documents on his desk, walked outside, and went home to rest.

Less than half an hour after Hiruzen left, the office was dimly lit, with only a little moonlight to support it.

Without making a sound, a bulge rose on the office floor, and a pale golden eye, not particularly bright, surveyed the office.

Its body slowly detached from the floor, transforming into a soft, sticky, twisted humanoid figure, and began silently searching for recently released mission information from Konoha on the desk.

I don't know how much time had passed, but suddenly a dark shadow approached quickly, and with a soft swoosh, the gleaming silver ninja sword sliced ​​through the air.

Without any mercy, he chopped the twisted humanoid figure in two.

His upper body flew off and slammed against the wall with a thud.

He stared intently at the suddenly appearing Konoha Anbu with a pair of pale golden, inorganic eyes.

There was no fear in its eyes, it just uttered some incomprehensible gibberish.

Then, under the astonished gaze of the Konoha ANBU, the lower half of the body that had been resting beside the desk disappeared into the floor, which it had mistaken for a swamp.

Upon seeing this, the Konoha ANBU member immediately swung his blade and slashed at the upper body of the humanoid figure stuck to the wall again.

Just like the lower body before, the upper body treated the wall like a swamp, sinking completely into it as it began to retreat.

After the blade sliced ​​through the air, it only struck the hard wall, leaving a crack.

Chapter 81 Fun

It was a dozen minutes later when the Third Hokage, Hiruzen, returned to his office in the Hokage Building. He looked at the wall in his office, which had a crack from the fight, the mark left by the ANBU ninja with his ninja sword.

"what happened?"

Hiruzen looked at the four Anbu ninjas who appeared in front of him and asked what exactly had happened here.
