Time flew by, and it was soon the end of August.
The second semester of the Ninja Academy was about to begin.
Over the past few days, Gojo Yoru had figured out exactly where the black Space-Time Chakra came from and what it could currently be used for.
Just as Senjutsu Chakra is a special energy formed by the combination of Chakra and natural energy, Gojo Yoru's Space-Time Chakra was a product of combining physical energy, spiritual energy, and the power of space-time.
Unlike Senjutsu Chakra, which requires absorbing natural energy from the outside world into the body, Gojo Yoru's cells could secrete this special space-time power.
However, Gojo Yoru discovered that only a portion of his cells could secrete space-time power. The amount was limited, unlike physical and spiritual energy, which could be extracted from all 130 trillion cells.
Cells wouldn't undergo such changes for no reason. Gojo Yoru's preliminary hypothesis was that there was something wrong with his heart.
The black heart projected in his mind might be hiding some secret.
But if there was a secret, logically speaking, it shouldn't have taken so long to manifest, only "activating" when he turned six.
Perhaps it wasn't his heart that had a problem, but... the soul that came to this world had a problem!
Whichever it was, it wasn't something Gojo Yoru could investigate right now.
Moreover, Gojo Yoru had a premonition that the feeling which resembled a precursor to sudden death might just be the beginning, and it would likely occur many times in the future.
After experiments over the past few days, based on Gojo Yoru's current strength, there were two usages for the Space-Time Chakra.
First was Intangibility. In fact, he didn't need to manifest the Space-Time Chakra outside his body; Gojo Yoru's body could achieve intangibility internally.
As long as he formed hand seals to mobilize the Chakra and let the Space-Time Chakra flow through his meridians, any part with the black Chakra could become partially intangible. If he could flood his entire body with it, he could achieve full-body intangibility.
Second was Attack. However, it couldn't be used to perform Ninjutsu, at least not something Gojo Yoru could do right now.
The reason he discovered that Space-Time Chakra could be used for attacking was that he used the Chakra Blade inherited from his family to try and draw the black Chakra out of his body.
Then...
The Armament Haki from the One Piece world appeared in the Naruto world.
The Chakra Blade in Gojo Yoru's hand actually turned into a Black Blade!
And it was an indestructible Black Blade. Unless it met a force of law capable of contending with space-time, any object, no matter how hard, would be cut in two when struck by Gojo Yoru.
Gojo Yoru had tested it himself. Just by gently dragging the tip of the blade across the ground, a smooth, straight cut appeared through both the bricks and the soil beneath.
Shuriken, kunai, iron blocks, wooden training dummies, gemstones... no matter how hard the object, in front of Gojo Yoru's Black Blade, they were as fragile as thin paper.
With every slash, Gojo Yoru's self-confidence surged.
These two usages of Space-Time Chakra were practically a pirated version of the double-eye Kamui.
Although Gojo Yoru currently needed hand seals to mobilize the Space-Time Chakra, and it took a certain amount of time to flood his whole body—during which he couldn't move—and although drawing the Space-Time Chakra out of his body was extremely difficult, requiring a Chakra Blade and being unusable for Ninjutsu...
Gojo Yoru had more than one method to solve these issues.
As long as he resolved these limitations, he would be invincible in both offense and defense until his Space-Time Chakra ran out!
This goal filled Gojo Yoru with the motivation to become stronger.
...
Konoha Year 30, September 1st.
Just as usual, Gojo Yoru got up at six o'clock to go for a morning run.
He didn't give up on physical exercise and building a solid foundation just because he had awakened a powerful force.
The original Uchiha Obito was the best negative example.
Despite obtaining Uchiha Madara's Ninjutsu inheritance and the Gunbai, having half his body made of Hashirama cells, and possessing terrifying Chakra levels and pupil power, he could only fight to a draw with Hatake Kakashi when he couldn't use Kamui's intangibility.
Gojo Yoru wouldn't rely solely on space-time abilities like him. At least until his Space-Time Chakra surged to the point where he could squander it freely, he would only treat intangibility and the Black Blade as trump cards.
Gojo Yoru didn't have X-ray vision, nor had he mastered sensing techniques, so he didn't know what the Chakra capacity of an ordinary Genin was.
However, in the original work, when Uchiha Sasuke performed the Fireball Jutsu, his Chakra amount amazed Hatake Kakashi. This indicated that for an ordinary Genin, having enough Chakra to perform a C-rank Five Elements Ninjutsu was already remarkable.
As for Gojo Yoru, he had already begun training in C-rank Five Elements Ninjutsu, and his Chakra amount was sufficient to execute a C-rank Ninjutsu with ease.
This meant his Chakra capacity far exceeded that of an ordinary Genin.
This was one of Gojo Yoru's few advantages.
Perhaps it was because a transmigrator's soul was stronger, or maybe it was the Gojo family genes, or even the influence of the "unknown" inside him, but Gojo Yoru's spiritual energy was very powerful. Coupled with money and planned investment in his body, his Chakra amount far surpassed his peers.
In the first grade, his Chakra was already stronger than an ordinary Genin.
Space-Time Chakra occupied one-third of his total Chakra, so the amount was probably not less than that of an ordinary Genin.
Even so, this bit of Space-Time Chakra was not nearly enough.
Because Gojo Yoru discovered that his cells could only extract this specific amount of space-time energy. Once used, it could be regenerated, but he couldn't break through the current upper limit.
This discovery made Gojo Yoru happy rather than alarmed.
It could be regenerated after use, but the maximum amount was locked. Wasn't this an invisible bottleneck?
If, before this, Gojo Yoru still doubted whether that feeling akin to sudden death would appear again, now he was 100% certain that the feeling would definitely return.
When that time came, more cells in his body would be able to extract space-time energy.
When all his cells could extract space-time energy, ordinary Chakra would be completely replaced by Space-Time Chakra. This ability would be a "Kekkei Genkai," and Gojo Yoru might also figure out the secret hidden within his body.
Therefore, Gojo Yoru called that feeling of sudden death—Evolution!
...
Finishing his morning exercise, Gojo Yoru went home for a quick shower.
In front of the full-length mirror, Gojo Yoru zipped his jacket up to his chest. Looking at the reflection of the white-haired child wearing a blue jacket, a white shirt, and black Bermuda shorts, with a face full of baby fat, looking tender and cute, he couldn't help but tilt his head and grin: "How cute!"
However, after turning around, Gojo Yoru returned to his expressionless look.
Hands in his pockets, Gojo Yoru walked out of the house and headed towards the school.
Entering the school gate, students who had seen how Gojo Yoru fought or heard of his fierce reputation stopped and moved out of his way.
Even so, Gojo Yoru didn't let them off.
"Trash, what are you looking at?"
Meeting the eyes of the students secretly peeking at him, Gojo Yoru spoke coldly.
"So... sorry!"
Those icy blue eyes seemed to genuinely radiate a bone-chilling coldness, scaring the students into trembling. They hurriedly apologized with shaking voices, then lowered their heads or turned away.
Wherever the School Tyrant passed, no one dared to approach.
