"Kushina, I'll cast the Spirit Transformation Technique later. Use the Mind's Eye of the Kagura to help me with an experiment."
"Okay."
After the sensing training ended, Gojo Yoru didn't take Uzumaki Kushina back to Konoha but teleported to a cave.
Inside the cave, it wasn't just the two of them; there was also an unconscious ninja lying on the ground.
Gojo Yoru first formed seals with both hands, fully releasing his spatial sensing. After confirming there were no White Zetsu clones around, he said to Uzumaki Kushina, "Do you remember my Chakra aura?"
"Mhm mhm..."
Uzumaki Kushina nodded repeatedly.
In the entire Konoha, no one was more familiar with Gojo Yoru's Chakra aura than her.
This was why Uzumaki Kushina could intercept Gojo Yoru at the entrance of the Hokage Building as soon as he returned to Konoha.
"Very good."
Gojo Yoru pointed at the ninja on the ground and continued, "Then remember this guy's Chakra aura. I'll possess his body later. Pay attention to see if there are any changes in his Chakra aura."
"Okay."
Uzumaki Kushina immediately used the Mind's Eye of the Kagura to sense the ninja's Chakra aura.
When Uzumaki Kushina opened her eyes and nodded, Gojo Yoru immediately sat cross-legged, closed his eyes, and formed a Rabbit seal with both hands.
In a perspective invisible to Uzumaki Kushina, a spirit body looking exactly like Gojo Yoru, even with clothes, emerged from the top of his head and floated in the air.
Gojo Yoru felt his vision suddenly elevate, seeing himself sitting cross-legged, the unconscious ninja on the ground, and Uzumaki Kushina whose face suddenly turned pale.
Not only that, Gojo Yoru could also see the Chakra inside that ninja and Uzumaki Kushina, and sense their Chakra aura.
Without forming seals, Gojo Yoru could sense energy fluctuations in all directions, with a range more than ten times larger than usual.
This was one of the characteristics of the Super S-rank Yin Release Secret Technique.
It was Gojo Yoru's first time casting the Spirit Transformation Technique. A few days ago, after sensing that spiritual energy and physical energy could be perfectly separated, he knew he had mastered the Spirit Transformation Technique.
But worried that there might be White Zetsu clones in Konoha, or Black Zetsu who hadn't yet become the incarnation of Uchiha Madara's will watching him, highly likely to discover his spirit body state, plus developing spatial sensing was more important, Gojo Yoru didn't cast the Spirit Transformation Technique in Konoha.
Entering the spirit body state for the first time, just this sensing enhancement characteristic made Gojo Yoru feel that the Spirit Transformation Technique was worthy of being a Super S-rank Secret Technique.
Impure World Reincarnation and the Eight Gates could be quickly mastered as long as a genius with suitable talent was found; at most, they were S-rank difficulty.
Only the Flying Thunder God Technique and Spirit Transformation Technique, these two Super S-rank Secret Techniques, were simply techniques choosing people.
Needless to say about the Flying Thunder God Technique, the cultivation conditions for the Spirit Transformation Technique required not only suitable spiritual energy and Yin Release Chakra but also matching Yin Release talent. It would take years of cultivation just to barely get started.
To master it quickly like Gojo Yoru, one also needed Chakra control at the pinnacle of the Ninja World. The cultivation conditions were as harsh as the Flying Thunder God Technique.
If Gojo Yoru still only had veteran Chunin level Chakra, even after completing the second evolution, he couldn't cultivate the Spirit Transformation Technique.
Because his spiritual energy and Yin Release Chakra were not strong enough to condense a spirit body to leave the physical body.
Just like Rock Lee could open the fifth gate of the Eight Gates at twelve but could only open the sixth gate at sixteen.
Unless one was a super genius, the Spirit Transformation Technique had a bottleneck that required adulthood to break through.
Only an adult body and spirit could support them in bearing the side effects brought by breaking this bottleneck.
This was also why many Ninjutsu were listed as Forbidden Jutsu; casual cultivation could easily lead to life-threatening danger.
Just as Gojo Yoru was preparing to feel the spirit body state and then possess the ninja, Uzumaki Kushina's panicked voice suddenly reached his ears: "Yoru, did you succeed? Why did all the Chakra in your body disappear?"
"Chakra disappeared?"
Gojo Yoru raised an eyebrow and looked at his body doubtfully.
The next second, a trace of surprise flashed in Gojo Yoru's eyes: "What's going on?"
He hadn't noticed just now, but Gojo Yoru now realized that from the spirit body perspective, his body had no energy fluctuations at all.
As if this wasn't Gojo Yoru's physical body, but a corpse.
This was very unusual.
Just as Five Elements Ninjutsu users could convert Chakra into Five Elements nature transformations, Yin Release and Yang Release, as hidden attributes, although special, also converted Chakra into nature transformations.
For example, Genjutsu users converted Chakra into invisible Yin Release Chakra, but only converted the part of Chakra used for the technique.
The Spirit Transformation Technique was no exception.
Moreover, the Spirit Transformation Technique must leave Chakra in the body to facilitate positioning and return to the physical body.
It was also for this reason that Kato Dan in the original work was found and killed by the enemy.
If the body became a corpse, the Spirit Transformation Technique would be an invincible existence, meaning the body could be sealed in a storage scroll.
But now, neither Uzumaki Kushina nor Gojo Yoru's spirit body could sense a trace of energy fluctuation from his body.
Most critically, Gojo Yoru was very certain that he left Chakra in his body and didn't use Space-Time Chakra when casting the Spirit Transformation Technique.
Ignoring the possession experiment, Gojo Yoru hurriedly returned to his main body.
Just opening his eyes, Gojo Yoru saw Uzumaki Kushina leaning over, asking worriedly: "Yoru, are you okay? Did the technique fail just now?"
"No, the technique was very successful." Gojo Yoru shook his head, then asked, "Kushina, you said my Chakra disappeared completely just now. What did you mean?"
Uzumaki Kushina replied truthfully: "I was using the Mind's Eye of the Kagura just now, and then I saw your Chakra disappear instantly. Not just Chakra, even life fluctuations were gone, just... just like you were dead."
Although knowing it was inauspicious, Uzumaki Kushina still said the last sentence.
Hearing this, Gojo Yoru fell into deep thought.
He never knew that Uzumaki Mito could barely see his Space-Time Chakra.
Gojo Yoru wasn't surprised that Uzumaki Kushina couldn't sense Space-Time Chakra; this was high-dimensional sensing shielding.
But not sensing the remaining Chakra and the body's energy fluctuations was a bit strange.
Could it be that after his spirit left the body, Space-Time Chakra automatically hid his aura?
Only intangibility could hide all aura.
Thus, Gojo Yoru said to Uzumaki Kushina: "Kushina, I'll cast the Spirit Transformation Technique again. After you sense my Chakra disappear, touch my body to see if it merged into space."
"Okay."
Knowing Gojo Yoru didn't fail, Uzumaki Kushina was no longer panicked.
When Gojo Yoru formed seals again to cast the Spirit Transformation Technique, sensing his Chakra disappear, Uzumaki Kushina reached out and gently touched his body.
The scene of her hand passing through his body didn't appear; Uzumaki Kushina's hand landed solidly on Gojo Yoru.
"Eh?"
As if sensing something, Uzumaki Kushina showed a curious expression: "Clearly Chakra and energy fluctuations disappeared, but the body still has temperature."
"Without temperature, that would be dead." Gojo Yoru opened his eyes, speechless.
"Yoru, what's going on? Could it be that this is the Spirit Transformation Technique?" Uzumaki Kushina stared at Gojo Yoru with bright eyes.
"Don't disturb me for now. Go check that guy's condition; don't let him wake up." Gojo Yoru waved his hand and fell into deep thought again.
This uniqueness different from Kato Dan made Gojo Yoru, whose talent had improved for the second time and whose mental agility had also strengthened, have a vague flash of inspiration in his mind.
This uniqueness might not be simple, or it might have huge room for manipulation.
He might have severely underestimated the Spirit Transformation Technique.
This Super S-rank Yin Release Secret Technique, for him possessing the Space-Time Kekkei Genkai, might not only be used to develop spatial sensing. He could also use the characteristic of this technique perfectly separating spiritual energy and physical energy to do more things.
As Gojo Yoru had such thoughts, the inspiration in his mind grew larger, seeming to approach him.
Suddenly, Gojo Yoru remembered an experiment thrown into a corner due to countless failures.
This experiment was... Space-Time Release: Shadow Clone.
After ordinary Chakra could merge with Space-Time Chakra, Gojo Yoru didn't develop the Phantom Body Flicker Technique first but used it to cast the Shadow Clone Technique.
The mixed Chakra successfully created a physical body, but the Shadow Clone had no independent consciousness, and its body distorted and flickered from time to time, like a glitchy monitor screen.
This problem remained unsolved even after Gojo Yoru completed the second evolution and his Chakra control reached the pinnacle of the Ninja World.
Gojo Yoru thought the space-time power in his body possessed a [Unique] characteristic, usable only by his main body, not shareable with Shadow Clones, hence the lack of independent consciousness.
Thinking carefully now, if there really was such a characteristic, the mixed Chakra shouldn't be able to create a physical body.
After all, Gojo Yoru's main body could only release space-time power externally by covering Ninjutsu with it.
Simply releasing Space-Time Chakra, Gojo Yoru at "Stage Two" couldn't do it.
Other external release Ninjutsu succeeded, so why did the "Space-Time Shadow Clone" fail?
Now it seemed it wasn't that space-time power had a [Unique] characteristic, but that Gojo Yoru... wasn't qualified enough.
The Space-Time Shadow Clone lacked an important link, something Gojo Yoru at "Stage Two" couldn't compensate for.
If he thoroughly understood the Spirit Transformation Technique, Gojo Yoru might be able to fill this important link.
Even if not now, "Stage Three" definitely could.
At this moment, Gojo Yoru was even more determined.
The third evolution was definitely a watershed in the "Ladder to Godhood."
"Yin Seal—Release!"
Temporarily dismissing the idea of restarting the "Space-Time Shadow Clone" experiment, Gojo Yoru suddenly unsealed the double Yin Seals again, using the full-power micro-adjustment of the Yin Seal to raise his body functions to the optimal state.
In this state, Gojo Yoru, like opening the first gate of the Eight Gates, could achieve 100% control over both types of Chakra.
"Phew..."
Taking a deep breath, Gojo Yoru suddenly formed a Rabbit seal again.
But this time, after converting the Chakra in his body into Yin Release Chakra, he didn't immediately condense a spirit body to leave the flesh but waited for something.
Soon, the Space-Time Chakra independent of ordinary Chakra, under Gojo Yoru's dual-tasking control, flowed along the meridians to the brain, merging with the Yin Release Chakra.
With external intervention, Gojo Yoru's spirit body delayed emerging from the body.
Until the double Yin Seal micro-adjustment intervened, Gojo Yoru's spirit body saw a ray of white light in the darkness.
The spirit body lost in darkness rushed towards that ray of white light without hesitation.
As the white light grew larger, the darkness where Gojo Yoru closed his eyes was suddenly torn apart.
Vision elevated again, and Gojo Yoru saw the familiar cave and the three figures.
Gojo Yoru immediately examined his spirit body state, and the corner of his mouth rose slightly: "Success."
Ordinary Spirit Transformation Technique spirit bodies were transparent white, with built-in sensing shielding. Even Edo Tensei Madara's Rinnegan couldn't see them, only vaguely sensing something nearby.
At that time, Uchiha Madara was still at the Super Kage level stage, not yet a higher-dimensional existence.
Since even Uchiha Madara at this level could vaguely detect it, the Spirit Transformation Technique certainly had no effect on Six Paths level sensing.
Gojo Yoru was very certain that when Uchiha Madara revived and retrieved the Rinnegan, as the true owner of the Rinnegan, he would definitely be able to see the Spirit Transformation Technique spirit body.
Even Nagato, after mastering the Six Paths Technique, might be able to see the Spirit Transformation Technique spirit body.
After all, the most basic Human Path of the Rinnegan was extracting the enemy's soul.
However, just like the Rinnegan's exclusive Dojutsu and summoning the Gedo Statue, Edo Tensei Rinnegan were fake eyes; some abilities required real eyes to use.
The Human Path was the absolute nemesis of the Spirit Transformation Technique, something even Gojo Yoru dreaded extremely.
But now, Gojo Yoru had no fear.
Perhaps the real Rinnegan could still see the existence of his spirit body, but the power of the Human Path definitely couldn't counter him.
Because... Gojo Yoru's spirit body had mutated.
Gojo Yoru's spirit body was no longer transparent white but transparent black.
His Spirit Transformation Technique had turned into Space-Time Release: Spirit Transformation Technique.
As the eighth special attribute not belonging to Yin, Yang, and the Five Elements, space-time power was a universal existence. As long as your Chakra control met the standard, it could cover any attribute Ninjutsu.
Non-elemental Rasengan was like this, Five Elements Ninjutsu were like this, and Yin-Yang attributes were the same...
Although space-time power was consumed every second, before Space-Time Chakra was exhausted, Gojo Yoru's space-time spirit body was in an absolutely invincible state like using intangibility. Even abilities targeting the soul couldn't hurt a hair. The already powerful sensing shielding was instantly raised to a higher curtain; perhaps only ultimate Dojutsu could see him.
Unfortunately, the Spirit Transformation Technique assassination was a contest of spiritual energy and Yin Release Chakra; otherwise, Gojo Yoru would be the most unsolvable assassin in the Ninja World right now.
He just didn't know if Space-Time Chakra could work in the spiritual space. If so, it meant that before Space-Time Chakra was exhausted, Gojo Yoru's spirit body could also use space-time abilities in the enemy's spiritual space.
In that case, Gojo Yoru might be able to help Uzumaki Kushina tame the Nine-Tails in advance.
More critically, even if targeted by the Sage of Six Paths in soul form, Gojo Yoru wouldn't fear this true God of Shinobi who could travel between the real world and the Pure Land.
Even... Gojo Yoru could travel from the real world to the Pure Land.
These thoughts flashed by one by one, and Gojo Yoru's eyes were filled with shock.
Feasible... very feasible, just that he wasn't qualified enough at this stage.
Just like the Yin Seal was a Shinjutsu level for Gojo Yoru, or even a divine technique more powerful than Shinjutsu.
At this moment, in Gojo Yoru's eyes, the Spirit Transformation Technique was his second divine technique.
"Eh?"
Quickly calming his emotions, Gojo Yoru was about to examine his body to see if he could see the remaining energy fluctuations inside his body while in the space-time spirit body state.
Suddenly, as if sensing something, Gojo Yoru's gaze shifted to Uzumaki Kushina, and intense joy burst from his eyes.
In Gojo Yoru's sensing, the energy inside Uzumaki Kushina was visible at a glance.
The Uzumaki Clan's powerful vitality and Chakra, along with two unfamiliar Chakras inside her body.
One was the vast Nine-Tails Chakra like an ocean, and the other was a weak but very strong Chakra seal like the thin film on the surface of a Rasengan.
On this Chakra, Gojo Yoru also sensed an unfamiliar Chakra aura.
Although he didn't have this level of sensing back then, Gojo Yoru was very certain this was Uzumaki Mito's Chakra.
"Can I even use spatial sensing?" Gojo Yoru murmured to himself, but his gaze wasn't on Uzumaki Kushina's abdomen, but on her wrist.
In Gojo Yoru's perspective, there were two Chakras of different colors on Uzumaki Kushina's wrist, one blue and one black.
The blue one was the Ouroboros pattern engraved on the wrist like a bracelet, which was the ordinary Chakra version of the Flying Thunder God formula.
The black one was the Space-Time Release: Flying Thunder God formula attached to the clothes inside the kimono sleeve.
The next second, Gojo Yoru's spirit body suddenly appeared beside Uzumaki Kushina without warning.
The transparent black spirit body instantly shed a little blackness, soon covered by other blackness, but the overall color was no longer so dense.
Looking at Uzumaki Kushina in front of him, forming seals with both hands and maintaining the Mind's Eye of the Kagura state to monitor the unconscious ninja, if not for being unable to do so, Gojo Yoru really wanted to cup her face and kiss her hard to vent the joy in his heart.
The spirit body in space-time state could even use the Flying Thunder God Technique.
What did this mean?
This meant that Gojo Yoru's self-preservation ability would be greatly improved.
As long as he retained enough Space-Time Chakra, his spirit body could return to his physical body almost instantly.
When going to find Konan, he didn't need to risk going to a location near her, increasing the chance of being discovered by Black and White Zetsu, and spending a long time flying.
Gojo Yoru only needed continuous teleportation to appear beside Konan instantly and possess her body at space-time speed.
Plus high-dimensional shielding, no one could discover his possession.
If not for being cautious and the experiment not yet completed, Gojo Yoru really wanted to try it out.
