The Shinobi World, Year 60 of Konoha.
The night was deep. The moon hung high in the sky, bathing the world below in a bright, gentle light.
In the southeastern corner of Konoha, nestled against the edge of the forest, stood a small wooden house.
It wasn't large, and inside lived a young boy named Kamisato Yuehua.
"Hu~"
He exhaled slowly, releasing a breath of turbid air. His slightly closed eyes suddenly opened, gleaming with brilliance—an almost fluorescent light shimmered within them.
Kamisato Yuehua was twelve years old this year. Though still young, his handsome features carried a delicate, almost charming quality.
"At last… I've permanently opened the Third Gate of the Eight Inner Gates."
Muttering to himself, a faint smile curled his lips. He was in high spirits.
"It's been a year since I arrived in the ninja world."
"In just one year, I've gone from being an ordinary student at the Ninja Academy to permanently opening the Third Gate, regularly opening the Sixth Gate, and even forcibly unlocking the Seventh Gate of the Eight Inner Gates."
"In terms of pure physical strength, I'd already rank as an Elite Jōnin at twelve years old!"
"And with the rest of my skills… I should be close to Kage-level, shouldn't I?"
"The only thing I lack now is true combat experience—the kind of experience forged on the brink of death time and again."
"Unfortunately, in my previous life, I was just an ordinary orphan with no family or special bloodline. It's only been a year since I transmigrated here… otherwise, I'd be even stronger by now."
"After all… I possess heaven-defying comprehension!"
This extraordinary comprehension was the cheat Kamisato Yuehua brought with him upon transmigrating.
But just how "heaven-defying" was it?
Lacking a bloodline or any family secret techniques, Kamisato Yuehua had devised an original cultivation method that combined Taoist principles from his previous life with this world's chakra extraction techniques—allowing him to absorb the essence of the sun and moon to temper his body!
He had named this technique the [Sun and Moon Eclipse Technique].
Later, by chance, Kamisato Yuehua encountered Might Guy and, through determination and the Will of Fire, earned the right to learn the Eight Inner Gates Technique.
Then, through his own comprehension and deduction, he combined the technique with his Sun and Moon Eclipse Technique—creating an entirely new form of the Eight Inner Gates.
The original Eight Inner Gates was notoriously difficult to master, requiring tremendous willpower and effort. Though it granted incredible strength, it came at a steep price: tremendous damage to the user's body, and death upon opening the final Gate of Death.
Worse still, its effects were temporary. Once the gates closed, the user would soon become incapacitated.
For ordinary ninjas, the drawbacks far outweighed the benefits.
But Kamisato Yuehua new Eight Inner Gates Technique had none of these flaws. His gates could be opened permanently!
With the constant body refinement of the Sun and Moon Eclipse Technique, and the continuous healing from absorbing the sun and moon's essence, the side effects were eliminated entirely.
As long as Kamisato Yuehua body continued to develop, the day would come when he could open all eight gates permanently.
Most importantly—he no longer needed to train tirelessly day after day. The only requirement now was time.
In addition to the Sun and Moon Eclipse Technique and the New Eight Inner Gates Technique, Kamisato Yuehua had also created several original A-rank ninjutsu.
This was the true power of his heaven-defying comprehension.
"To become truly strong, one needs three things: comprehension, physical talent, and will."
"Your physique determines your lower limit. Comprehension determines your upper limit. And your will allows you to break through the limits of both."
"In this world, those who excel in physique would be the Ōtsutsuki Clan and those of similar bloodlines—even the weakest among them possess power approaching that of the Sage of Six Paths."
"Yet the Ōtsutsuki, despite their overwhelming physiques, seem to lack true insight. The techniques they wield rely almost entirely on their bloodline; they've created nothing truly groundbreaking."
"In contrast, the paragons of comprehension would be Senju Tobirama, Orochimaru, and Yakushi Kabuto. Especially Tobirama—creator of the Impure World Reincarnation, Flying Thunder God Technique, and Shadow Clone Technique."
"Yet lacking the Ōtsutsuki's physique, even Tobirama's growth was ultimately limited. Had he possessed their bloodline, his strength would have reached unimaginable heights."
"Then there are those defined by pure will—Might Duy, Might Guy, and Rock Lee. Their determination is unmatched."
"But with their average physiques and limited comprehension, the pinnacle they can reach is the temporary power of the fully-opened Eight Inner Gates."
In Kamisato Yuehua's mind, he pictured these figures—legends in their own right, each excelling in one domain: physique, comprehension, or will.
But none combined all three.
Throughout ninja history, no one had ever embodied the perfect fusion of body, mind, and spirit.
Yet Kamisato Yuehua believed that person would soon emerge.
And it would be him.
Of course, willpower was not in question.
Even with the body of an ordinary mortal, Kamisato Yuehua—with his heaven-defying comprehension—was confident he could transform his physique.
"Doesn't the Sage Mode of Ryūchi Cave allow even ordinary bodies to evolve?"
"Forget what happened to Orochimaru—just look at Yakushi Kabuto. His body underwent genuine evolution."
"While my Sun and Moon Eclipse Technique is strengthening me daily, if I want to surpass even the Ōtsutsuki in raw physical potential, I'll need to refine it further."
"I must go to Ryūchi Cave."
"And not just Ryūchi Cave—Mount Myōboku and the Shikkotsu Forest as well. I need to visit all three Sage locations."
"Comprehension alone isn't enough. True deduction requires knowledge and experience. The teachings behind the three Sage Modes will be invaluable to me."
"And what better opportunity than the Chūnin Exams? The Three Legendary Sannin of Konoha all trained at those places… this exam might be my best chance."
Kamisato Yuehua's thoughts raced as he quickly sketched out a plan in his mind.
For now, that rough outline would suffice.
After all, the Chūnin Exams were still a ways off, and many variables remained.
"The immediate priority is tomorrow's Ninja Academy Graduation Exam. Naruto, Mizuki… and the Scroll of Seals—that's a godsend."
A knowing smile appeared on Kamisato Yuehua's lips as he recalled the events from the original story.
By tomorrow… the secrets of the Scroll of Seals would soon be his!
