Konoha: Offer your heart to the Hokage!

After six long years, he finally developed the first version of the Impure World Reincarnation technique himself.

He subconsciously pressed his hand on the left chest of Edo Tensei No. 1 and released the Earth Grudge.

Sure enough, it was just an empty hole; there was no heart inside.

Theoretically speaking, a ninja without a heart has no physical energy and therefore cannot refine chakra. Without refining chakra, they cannot even perform the most basic ninjutsu and possess no combat power.

Tobirama, who initially developed the Impure World Reincarnation technique, must have faced similar challenges. Left with no other option, he combined Impure World Reincarnation with the Mutual Explosive Tags technique to create a self-destructing truck that dragged the enemy down with it.

However, the ninja world is not a place where science is entirely applied.

In an unknown future version of the Impure World Reincarnation, Kabuto inexplicably developed the ability to possess "unlimited chakra."

Simply outrageous.

After much research, I still couldn't find a clue. I could only temporarily reconcile with my own scientific spirit and hope that the wisdom of future generations and puppetry could solve the problem.

Orochimaru and Kabuto's research findings were indeed not something that could be easily replicated simply by copying their ideas.

Looking at the motionless Edo Tensei No. 1 lying on the experimental table.

He then resumed thinking.

Undoubtedly, he has made far greater progress than Tobirama Senju in the development of the Impure World Reincarnation technique.

Even if Tobirama is a genius at developing ninjutsu, it will be difficult for him to easily catch up with such a gap. Especially with Shinji proposing "division of labor" in the future, Tobirama's progress will be slowed down by him.

However, the symbolic meaning of this "First Edition: Impure World Reincarnation" outweighs its practical value.

It doesn't seem to be intended for the mastermind behind the scenes; it only allows the caster to become a dream-fulfilling master in the ninja world. It can bring the consciousness of the dead back to the present world to make up for the regrets between them and the living.

"Self-directed action".

Even the restraints on Edo Tensei No. 1 were released.

Edo Tensei #1 immediately screamed in terror: "This...this is...I'm dead? No, I think I'm still alive. Was that a dream?"

After confirming that he could move normally and was conscious, Shen Er buried a kunai with a psychic talisman on it into the back of his neck, erasing the autonomous consciousness of Edo Tensei No. 1 and taking over the body from the soul level.

Impure World Reincarnation has two drawbacks.

If the deceased knows the order of the hand seals, they can break the psychic contract on their own and escape control.

Another flaw is similar to that of the Earthly Grudge.

Earth Grudge Parasites control living people with their tentacles, but they can be broken by ninjas with strong taijutsu and abundant Yang Release. Impure World Reincarnation binds the souls of the dead with its techniques and spirit, but it will also fail when it encounters the dead with lingering attachments.

The former can also assess the probability of failure by gathering information about ninjas in advance;

The latter involves the soul and spirit. The manipulated person may, at some moment, be awakened by some kind of bondage and have their inner obsessions awakened. This idealistic power is enough to break free from the control of the spell, thus leading to the failure of a certain action.

These are all shortcomings that need to be addressed in the future.

Specialization is key; leave professional tasks to professionals.

The development of subsequent advanced versions will be handed over to Tobirama Senju after Hashirama Senju's death. After Tobirama Senju's death, it will be handed over to Orochimaru; and after Orochimaru's death, it will be handed over to Kabuto Yakushi.

From Tobirama Senju's tactical perspective, the initial intention behind developing the Impure World Reincarnation technique was certainly not as simple as coordinating with the mutual multiplication of explosive tags.

Even if we take a step back and assume that this was truly his original intention...

Even Er could completely emulate Director Ai.

By subtly suggesting to Tobirama Senju the direction of their research into advanced Edo Tensei, they were guiding him towards independent combat.

Tobirama believed that everything was due to his own flash of inspiration and that he had led the evolution of the technique, but he did not realize when his thinking was gradually led astray by Shinji, deviating from his original intention.

Who influenced whom exactly?

She smiled faintly.

He raised his hand and used Earth Release to create a simple-looking coffin, with the words "Souvenir" printed on the coffin lid. Then he put the Edo Tensei No. 1 inside, and then put the coffin and the corpse into a summoning scroll.

This "first finished product" is a testament to the progress of his research on Edo Tensei from scratch.

It's worth keeping it safe.

As a memento.

Just like the Iron Man armor exhibition hall.

Even after dealing with the Impure World Reincarnation, he still hadn't stopped.

The essence of Impure World Reincarnation is a special extension of the art of spirit summoning.

After several years of continuous development and research into the Impure World Reincarnation technique, I have mastered it in many ways, and even my skill in spirit summoning has greatly improved.

Based on this, Shen Er further developed and designed a large-scale spirit communication array.

He slapped the ground with both hands, and with himself as the center, a large number of spiritual seals spread outwards along the ground, setting up a complete spiritual array in the Zen temple laboratory.

These summoning arrays are directly connected to the hidden coffins in the storage laboratory where ninja corpses are kept.

Hashirama's impending death means that war is not far off.

And Shen was an extremely cautious ninja.

To guard against extreme situations such as assassination or encirclement, he had prepared such a contingency plan.

As long as his five hearts aren't instantly destroyed, or he's caught in close combat without even the space to form hand seals and cast a summoning spell, he can summon his reserve hearts to his side at any time and replace them on the spot to prolong his life.

Chapter 75: The Dark Side Formation Plan (4K)

Before attending Takayuki Senju's wedding at the end of the month, there is still one thing I need to do.

That is to form a secret service.

Previously, Shen's influence in Konoha was limited, only involving the medical and educational fields. His sudden involvement in the military would easily arouse suspicion. But now that he has been appointed to arrange the distribution of the Tailed Beasts, this concern naturally disappears.

Furthermore, the operation of the Zen Temple Laboratory largely depends on the gap in the Death Forest.

Whether it's the secret service or the police department, their establishment will interfere with his covert arrangements.

But times have changed, and it's time to make a move.

The Anbu, short for Special Assassination Tactics Unit, is a violent, government-funded organization that only answers to the Hokage. It was initially established by Tobirama Senju shortly after becoming Hokage, and the system was subsequently imitated by other major ninja villages throughout the ninja world.

If we do nothing.

This violent organization will be completely controlled by Tobirama Senju and the future Hokage.

It's hard to say whether he will become Hokage in the future.

But he had to intervene and insert his own power into this power that belonged to the Hokage.

This is something that will be difficult to handle during the Tobirama period.

The best time is when Hashirama's lifespan is nearing its end.

Hashirama Senju was a complete idealist, his saintly nature unchanged, and he could accept even the Uchiha without any reservations.

What Shen Er needs to do is to get Uchiha clan ninjas into the Anbu.

Given his relationship with the Uchiha clan, the Uchiha people were essentially his eyes.

There are also branch families of the Hyuga clan.

The future Anbu might not have any Hyuga ninjas, perhaps because Tobirama worried that the Byakugan would uncover village secrets. But the naive Hashirama probably wouldn't have thought that far ahead, and could even have sent another loyal student, Hyuga Jun, into the Anbu.

Hashirama Senju knew he wouldn't live for many more years, but he didn't know that Shirou also knew he had a few more years to live.

The closer a person gets to death, the more they will want to carry out their will for as long as possible.

The Will of Fire is the will of Hashirama Senju.

His will was to enable all the ninja clans in the village to work together on an equal footing.

Therefore, even though sending ninjas from the Uchiha and Hyuga clans into the Anbu would provoke strong opposition from Tobirama Senju, this decision would likely still be forcefully pushed through by Hashirama, who was on his deathbed.

Once this precedent is set, it will be difficult for future Hokage to follow suit.

He could easily shut up the criticism with a statement like "The laws of our ancestors cannot be changed" or "The First Hokage once said so."

Anyone who opposes the Uchiha and Hyuga joining the Anbu is opposing the Will of Fire.

With the spies planted in the shadows, all of Konoha's arrangements will be secured for decades to come.

While the establishment of the Dark Division might cause some trouble for his covert operations in the short term, it's not a major problem. His need for human experimentation has diminished significantly with the successful development of the Impure World Reincarnation technique.

Furthermore, the smooth development of Akatsuki Village also provided Jin with a stable and legal channel. He could easily have Uchiha Yan send the human samples he needed into Gospel Hospital under various pretexts.

A dark underground network for human trafficking was thus legally and compliantly established.

Anbu, Konoha Police Department, Standing Patrol Units...

Shen Er plans to gradually extend his reach, planting his loyalists and spreading his influence throughout Konoha.

Even if the worst happens in the future, and everything he has done is exposed due to some accident, he will have to become a rogue ninja.

He could also retreat to Akatsuki Village with ease, and, relying on his hidden backup plans, continue to share Konoha's various resources like a lurking parasite.

He had complete control over everything, from external intelligence and the status of the Jinchūriki being cared for to lists of various employers and their commissions.

In the post-Hashirama era, with these accumulated resources, it wouldn't be impossible to create a new Konoha.

Of course, this is only the worst-case scenario.

She even preferred that she would stay safely in Konoha until the moment the Nine-Tails Jinchuriki was handed over.

Either Mito Uzumaki will pass the Nine-Tails on to Kushina, or Kushina will pass the Nine-Tails on to Naruto Uzumaki in the future.

He will wait until one of the Nine-Tails Jinchuriki is at his weakest point and then strike decisively.

...

After making the decision to form the Dark Division.

They even arrived at the Uchiha clan's territory together with Uchiha Chiri.

Thanks to the blessing of the Yin Seal, two years have passed and Zhili shows no signs of aging, forever frozen in her youthful and beautiful appearance in her early twenties.

In recent years, her relationship with Shen Er has become increasingly close.

Everything is progressing steadily along the established trajectory.
