Land of Fire, Konoha.
Inside an inconspicuous house in Konoha.
A pale-skinned, long-haired, snake-eyed little boy with purple eyeshadow stared blankly at himself in the mirror.
After a long while, Orochimaru finally came to his senses, made a few funny faces, and then did his signature tongue-out gesture.
His reflection in the mirror mimicked his actions, forcing him to accept the fact that he had transmigrated.
But… why Orochimaru? And specifically, in his childhood…
Recalling the original content of Naruto World, Orochimaru couldn't help but sigh.
Is Orochimaru powerful? Extremely powerful. Without special bloodlines or strange eyes, he survived to the very end by relying solely on his "cunning" survival ability, taken to the extreme.
The Third Hokage's Reaper Death Seal couldn't kill him, Sasuke couldn't kill him, Uchiha Itachi's Totsuka Blade couldn't kill him. Even after dying, he could revive through his Cursed Seal. In Boruto, he even lived younger and younger, showing signs of rejuvenation.
But the only problem was… all of Orochimaru's methods relied on scientific research and human experimentation.
Although he was also a scientist in his previous life, he studied physics, which had nothing to do with biotechnology…
Never mind… I'll start learning from scratch…
And… Ninjutsu… Bloodline… Chakra…
This World is truly interesting…
After a long time, Orochimaru exhaled, and remembering the peculiarities of this World, he couldn't help but feel a little excited.
He liked the feeling of gradually turning the unknown into the known, which was why he chose physics in his previous life.
For him, nothing was more exciting than an unknown World…
“However… this World is quite dangerous…”
Thinking of the Naruto Worldview, Orochimaru felt a headache coming on.
The Naruto World was constantly plagued by wars. Forget about research; just surviving was not a simple matter.
The only good news was that, according to his predecessor's memories, he had already graduated from the Ninja Academy.
And just like in the original story, he was assigned to Third Hokage Hiruzen Sarutobi's team, along with Tsunade and Jiraiya.
This was naturally good news for him, as who knew how those three ended up on the same team in the original Naruto story.
If he hadn't connected with the Third Hokage's network, he would have been completely screwed…
But… do Ninja Academy students graduate at six years old now?
Thinking of his age, Orochimaru couldn't help but complain.
Six years old! He's only six years old!
In his previous life, that was an age where even buying soy sauce was difficult, but in this World, he was already expected to go to the battlefield and kill people!
Although Naruto's era decades later was also ridiculous, at least he was twelve then!
Forget it~
Orochimaru couldn't help but shake his head. Since he couldn't change this World for now, he could only adapt.
Then he closed his eyes and began to refine Chakra according to the method in his predecessor's memory.
Although it was his first attempt, the process of refining Chakra was easier than he expected. Soon, he felt a warm current flowing through his meridians, finally gathering in his Dantian.
“Huh? My Chakra volume has increased?!”
Feeling his own Chakra, Orochimaru noticed the difference from his memories. His current Chakra volume was about fifty percent more than what he remembered.
This amount could no longer be explained by error…
“Is it because I transmigrated?”
Orochimaru murmured. According to the setting in Naruto, Chakra is a product of the mixture of spiritual energy and life energy within cells.
Did his transmigration cause him to absorb the memories of the young Orochimaru, leading to an increase in spiritual energy, which in turn affected his Chakra volume?
That's truly… interesting!
Touching Chakra for the first time, Orochimaru couldn't help but get excited.
Then, based on his memories, he began to practice Ninjutsu in the house.
As he came from a civilian background, all he knew were the most basic Three Body Technique taught at the Ninja Academy.
Family secret techniques, Bloodline Ninjutsu, and such, he naturally didn't know…
In the original story, most of Orochimaru's snake-related Ninjutsu were likely learned in Ryūchi Cave…
However, for someone like him, who was encountering Ninjutsu for the first time, this was already enough.
Among the Three Body Technique, he was naturally most interested in the Transformation Technique.
After all, this Ninjutsu was much more outrageous than the other two in the original story. It could not only change the body and gender.
It could even transform into animals and Ninja tools… simply absurd!
Thinking this, Orochimaru attempted to form hand signs, guiding the flow of Chakra within his body.
Then…
“Bang!”
Accompanied by a puff of smoke, Orochimaru's appearance changed, transforming from a child into a young man in a white lab coat.
“This is truly… amazing!!”
Orochimaru looked excitedly at his reflection in the mirror; it was his appearance from his previous life.
Then he felt himself up and down. What he touched was real flesh, not an illusion.
His physical body had truly been altered…
Afterward, Orochimaru, like a child who had found a new toy, began to transform into various things.
From people to animals, then to plants, and even inorganic matter…
Everything could be transformed. It wasn't an illusion, but a genuine change in his own material composition.
But it wasn't as powerful as he had imagined before.
Maintaining the transformed state required continuous Chakra consumption. The smaller the difference from his original self, the less Chakra was consumed.
Transforming into a human of similar build was the easiest. As for transforming into non-living things, simple structures like shurikens were fine, but complex structures couldn't be formed.
Moreover, the transformed objects were merely superficial; their material strength was completely inferior to the original.
But even so, it showed the outrageousness of the Chakra system…
The Clone Technique and Substitution Technique, however, were quite simple. The Clone Technique only created illusions, similar to quality projections, not solid clones like the Shadow Clone.
The Substitution Technique also just left a log in place the moment an attack was received, then ran away…
Compared to the Transformation Technique, which could completely alter oneself, they were still rather plain.
Thus, through experimentation, night unknowingly fell.
“That's enough for today…”
Orochimaru wiped the sweat from his forehead, his face even paler due to Chakra depletion, but his eyes were even more excited.
He wanted to figure out how Chakra affected human cells to achieve such feats, but a clever housewife cannot cook without rice. He currently lacked tools like a microscope.
And more importantly, he was meeting his instructor tomorrow, so he needed to rest early today.
Thinking this, Orochimaru opened the refrigerator and cooked a bowl of noodles to fill his stomach.
After eating, he took a quick shower and went to bed to rest.
The Naruto World has cell theory. Corresponding research tools should be available in the Konoha Hospital, right?
He should be able to get a set through Third Hokage's connections, right?
And relevant research materials…
Huh? Wait a minute, it seems these things are already available?
At this thought, Orochimaru's eyes lit up. He almost forgot that Tsunade Hime was about to become his teammate.
This future Hime was renowned for her Medical Ninjutsu. Why should he seek far and wide?
According to the future trajectory, Tsunade could research Medical Ninjutsu to that extent not just because of her extraordinary talent, but also because she must have had a vast amount of data.
And judging by the medical standards of Konoha Hospital, this data probably didn't come from there…
In other words, did it come from the Senju Clan?
In that case… as a teammate, it should be fine if he tagged along, right?
Thus, amidst his fantasies of a beautiful future, Orochimaru drifted off to sleep.
Then, accompanied by a feeling of weightlessness, Orochimaru instantly woke up.
When he came to his senses, he found himself in a space filled with grey mist.
And in front of him, there were several figures of varying heights, dressed differently, and even of different races.
From their expressions, they were looking at… him? with anticipation.
What… what exactly is going on here?!
(The setting of the Sannin graduating at 6 years old, while outrageous, comes from the 'Book of Databooks,' so I'm not making it up.)
(To clarify, I believe Naruto has a Dantian, or a place to store Chakra. This can be seen when Naruto's Nine-Tailed Chakra bursts out during the Chunin Exams; it emerges from his lower abdomen and then spreads throughout his body.)
