The underworld exerts a natural suppression on the souls of the dead.

Even as powerful as Gensou, he could hardly resist the pull of the underworld.

If he hadn't been cautious and only partially detached his soul from the Edo Tensei body on his first attempt, he wouldn't be standing here so easily now.

"In a semi-detached state, I can barely hold my ground against the underworld's pull. Fully out of body, I'd be powerless. Forget merging with my real body; I'd be dragged to the underworld the moment I tried to move."

Gensou stroked his chin, looking up at the clear, cloudless sky, deep in thought.

He needed to find a way to resist the pull of the underworld or enhance his soul.

"Soul..."

Gensou furrowed his brows.

There are countless jutsu in the world, but very few secret techniques concerning the soul.

No wonder, as the soul remains an enigma.

In life, he had focused more on chakra analysis, always cautious about meddling with the soul.

He couldn't afford to be reckless like Orochimaru, who didn't value others or himself, mangling his soul yet somehow surviving, purely by luck.

Gensou had limited research on the soul.

He tried the few soul-related secret techniques he knew in life, but none were effective.

Glancing once more at the rift in the underworld above, Gensou re-entered his Edo Tensei body with practiced ease, shaking his head:

"It's still no good. The resistance from the underworld is too overwhelming. The boundary between life and death isn't easy to breach."

The Rinnegan could succeed because of its exceptional nature.

Like the Ten Tails and Kaguya Otsutsuki, these extraterrestrial entities.

As the ultimate weapon of the Otsutsuki clan, the Rinnegan's wonders far exceeded resurrection.

"Unfortunately, I'm not the reincarnation of Asura or Indra. Even if I obtained their blood and cells, I couldn't evolve the Rinnegan."

Apart from the pure-blooded Otsutsuki clan, only Indra's reincarnations could awaken the Rinnegan by transplanting Asura's reincarnated body or cells.

Mixed offspring from Uchiha and Senju, or an Uchiha with Hashirama's cells, could never produce the Rinnegan, at most gaining Wood Release like Obito.

The Rinnegan was too far-fetched, better to set it aside for now.

After continuous attempts, night had fallen, and the temperature had dropped significantly.

Unbothered, Gensou sat cross-legged.

Edo Tensei bodies felt no pain, fatigue, hunger, or other physical needs.

Free from mundane distractions, he could fully focus on his predicament.

"Should I shift from chakra research to fully studying the soul?"

Gensou pondered, then dismissed the idea.

Even if successful, it would require immense time and effort.

Time was what he lacked the most now.

The Edo Tensei body wouldn't last indefinitely, and the remaining time wasn't enough for fruitful soul research.

Even Orochimaru, the greatest scientist in the ninja world, took over ten years to develop the Living Corpse Reincarnation technique.

Though highly talented, Gensou couldn't guarantee a quicker success.

If he were that formidable, he'd have completed the research on Kekkei Tota and been invincible, instead of struggling now.

In his current situation, self-reliance was impossible. External help was needed.

Gensou never underestimated others.

Despite being deemed equal to a god, he was only human with limited time in life. Compared to this millennium-old ninja world, more suitable methods surely existed.

Gensou pondered deeply.

As previously thought, he needed a soul technique that ignored distance and reached instantly.

Once his soul reached his real body and fused perfectly, like residing in the Edo Tensei body, the underworld could no longer affect him.

"Does such a soul technique exist in the ninja world?"

Gensou delved into his buried memories.

Suddenly!

A vivid, hot-blooded scene flashed in his mind.

A single phrase came to mind: "Big Chest."

No, not that! More accurately, the deceased boyfriend of that busty woman.

That man who dreamed big but wasn't cut out for it.

If memory served, his name was Dan.

As for his surname...

Heh heh.

"Kato" was a surname Gensou remembered vividly from studying many works in his previous life.

Even after all these years, this minor character, due to his surname "Kato," remained etched in his mind.

"Soul Body Separation Technique!"

Thinking of Dan, Gensou immediately recalled the fleeting jutsu from the Fourth Great Ninja War.

This S-rank soul technique, which allowed the user's soul to leave their body, traverse distances, kill enemies, control others' bodies, or enter their minds, was exactly what he needed.

Gensou's eyes lit up.

That's it!

He had to obtain it!

For the sake of his resurrection, Gensou couldn't wait any longer and stood up, ready to act.

But first, he needed to confirm something.

Where was the Soul Body Separation Technique?

Dan was dead, and summoning his Edo Tensei form would only force him to fight, not divulge the technique.

And learning a jutsu just by watching hand signs? Here, try clapping your hands to summon a Buddha.

The Soul Body Separation Technique was S-rank, not due to its effect, but its learning difficulty.

Learning jutsu carried risks.

Forbidden techniques were so named not for their lethality—after all, a Grand Fireball could also kill—but for the high chance of self-harm or even death during training.

That's why Konoha had the Book of Seals, prohibiting the spread of recorded techniques.

Like the Multi Shadow Clone Jutsu, those with average chakra reserves would die from chakra depletion if they attempted it.

Without restrictions, over ninety percent of ninjas trying it would perish.

Not every ninja was Minato Namikaze or Naruto Uzumaki.

Back to the point, Gensou wasn't worried about finding the Soul Body Separation Technique.

As warriors living on the edge, ninjas meticulously recorded their techniques, storing them in their clans or villages for posterity.

Dan, being a Konoha ninja, was no exception.
