Late at night, beneath a hazy moon, in a remote secluded grove.
Two clones with altered appearances appeared here, meeting secretly.
"Here, this is what you wanted. From now on, we're even."
Fugaku Uchiha was disguised as an ordinary villager. He tossed a ninja scroll to Satori Hyūga.
Satori Hyūga had black hair and black eyes. Slender and plainly dressed, he picked up the ninja scroll, scanned its contents, and nodded in confirmation.
"That's right. This is exactly what I needed."
"You didn't disappoint me."
Fugaku shot him a sidelong glance and warned, "The Akimichi clan's secret techniques aren't easy to obtain. If you get caught, don't you dare mention my name."
This was inherited knowledge—an exclusive treasure not meant for outsiders.
Despite appearing basic, it formed the foundation of the clan's power.
If someone with malicious intent got hold of it, they could develop counter-techniques.
Satori nodded, reassuring him, "Don't worry, I'm not that stupid. I only borrowed it for reference."
After all, how could such a handsome guy like himself want to turn into a fatty?
He intended to modify the technique—refining it to suit his own needs.
Seeing how firm Satori sounded, Fugaku finally felt slightly relieved.
What he feared most was Satori accidentally revealing the stolen technique.
Even with their high status, exposure would bring severe consequences.
"I've delivered the goods. I'll be off then."
With those words, Fugaku transformed into a puff of smoke and vanished on the spot.
Meanwhile, Satori found a quiet place and began studying the contents of the ninja scroll.
After memorizing its contents, he immediately set it alight, reducing it to ash.
Safer to keep it in the mind.
He scattered the ashes with a breath, and his shadow clone also dispersed into smoke and disappeared.
Inside the Hyūga clan compound.
Satori, quietly reading a book, suddenly shivered slightly, then a faint smile appeared on his face.
"The Akimichi clan's secret technique is indeed powerful—converting food into stored fat, then turning that fat into chakra when needed."
[Secret Technique: Conversion]
As soon as he grasped the technique's potential, ideas flooded Satori's mind in a torrent.
This secret technique was essentially the perfect complement to taijutsu.
Except for affecting the user's physique, everything else about it was great.
It was practically a godsend for enhancing combat endurance.
And the training involved? Just constant eating to build up fat reserves.
Following the training methods recorded in the scroll, Satori started experimenting by devouring all kinds of high-calorie foods.
Once these high-energy meals entered his stomach, his chakra rapidly digested and stored them.
This process continued endlessly, converting any excess energy into fat cells for storage.
Satori deliberately selected several types of calorie-dense, high-fat, and sugary foods.
Amplified by the secret technique, Satori's appetite grew monstrous—like that of a ravenous, insatiable beast.
His mouth resembled an endless abyss.
Satori Hyūga stood up and turned side to side in front of the mirror, studying his reflection closely.
His once-handsome face had grown round, turning him into an unexpectedly adorable little chubby boy.
However, Satori wasn't worried.
He yanked off his forehead protector and exhaled sharply. Instantly, he unlocked the First Gate of the Eight Gates.
In an instant, the limiter inside his body released, allowing his energy to surge and spill outward.
But this time was different.
The specialized fat he'd cultivated began behaving unusually.
It substituted for his physical energy, serving as the new consumable required for activating the Eight Gates.
Although not a perfect match, it still managed to offset part of the energy consumption.
The roundness Satori had just gained quickly shrank back down.
Activating the Eight Gates was now like driving a hybrid vehicle.
Previously relying only on gasoline—now electricity could work too.
Forget efficiency—this at least helped conserve resources when energy demand spiked.
This confirmed his theory was correct.
At least for him personally, this cultivation path was valid.
After confirming the result, he understood his next training method.
Satori stroked his chin in deep thought.
"Using fat to power the Eight Gates was the right choice. But how could he refine this technique further?"
Its main flaw required constant eating to build up fat stores.
And that's why every ninja in the Akimichi Clan inevitably ended up overweight in Konoha.
If he became a gluttonous fatty himself, people would quickly catch on.
Plus—he specialized in Taijutsu. The Gentle Fist relied on fluid, agile techniques.
The Iron Fist emphasized explosive, overwhelming force.
Gaining weight wouldn't make him stronger—it could even cost him his speed and agility under normal conditions.
He brainstormed various methods for improving the Akimichi's secret technique.
Not being part of the clan meant he lacked access to their complete family arts, so there was no need to follow their approach strictly.
Which meant he had far more room for modifications.
Rather than copying the technique completely, he could refine the fat into internal energy cells stored within his body.
"Should I solve this with scientific research or Ninjutsu? That's the question."
After careful consideration, Satori decided to test Sealing Techniques.
Sealing Techniques were nearly universal tools—capable of imprisoning everything from basic supplies to Kaguya Otsutsuki herself.
Given its unique properties, perhaps it could help regulate the special fat.
Without hesitation, he tried applying a sealing technique to some of the special fat within his body.
But the results weren't great.
This special fat was also part of his bodily balance. Sealing it off recklessly damaged his health.
He sought immortality—so techniques that harmed his body were immediately abandoned.
He also realized that the technique for sealing this secret fatty substance seemed remarkably similar to the Yin Seal [Yin Seal (used by Tsunade, one of the Sannin)].
If that's the case, wouldn't it be better to simply master the Yin Seal instead?
Satori Hyūga turned away from sealing techniques and embraced the path of scientific research.
His Shadow Clones worked tirelessly alongside Orochimaru, conducting research and experiments, gathering substantial scientific knowledge.
Compared to immersing himself in ninjutsu, Satori clearly leaned more heavily toward the scientific path.
"Perhaps it's time I built my own laboratory."
Gazing at the vast courtyard of his estate, Satori considered excavating a basement for experiments.
But building a basement beneath the Hyūga clan compound should be permissible.
His Main House status granted him near-complete freedom to act as he wished.
