Chapter 10: All Forbidden Techniques Lead to Tobirama
Since he couldn't stabilize the bird's physical and spiritual energy—or sense and sync with them—Kimura Takuya decided to switch the focus to himself.
Using his own body as the base, he attempted to transmit his own weight to the phantom clone.
Although he couldn't perfectly stabilize his own energies either, there was at least a chance to synchronize them.
As long as the phantom clone maintained continuous synchronization with him—
The clone's physical and spiritual energy would mirror his own.
Maintaining this link would essentially simulate a stabilized energy state.
Following this logic, Kimura Takuya resumed his research into the Perfect Transformation Technique.
And perhaps this time, he had found the right path.
Within just ten pages of notes, he managed to stabilize the transmission of his own body weight to the phantom clone, creating a unique solid-body clone.
"It worked!"
At this stage, Kimura Takuya was ecstatic.
Li Yao could feel the man's excitement through his writing—this was the joy of finally heading in the right direction, of seeing the long-dreamed-of Perfect Transformation Technique take shape.
Li Yao kept turning pages.
Sure enough, the progress became much smoother from that point onward.
After stabilizing weight transmission, Kimura went on to synchronize and transfer his body temperature to the clone.
The clone now had the same temperature as his real body.
Then he transmitted his heartbeat, blood flow, skin, hair, organs—even his own consciousness.
It felt like… the Perfect Transformation Technique was almost complete.
In the notes, Kimura Takuya's excitement grew with each entry.
Reading along, Li Yao couldn't help getting excited too.
Then, on the next page, he saw something that thrilled him.
"My Perfect Transformation Technique finally has hope!"
These words, written in large, bold characters across the top of the page, radiated pride and joy.
Li Yao eagerly read on. He had initially thought that developing the Perfect Transformation Technique would fall to him—but judging by the notes, Kimura might have already completed it.
The biggest hurdle—material conversion—had been passed.
Now, it was just a matter of copying the process. Transfer body temperature, heartbeat, and other biological data into the phantom clone until it became a real, living entity.
From there, the next step would be to derive a bird-form clone, and finally, the full Perfect Transformation Technique that could change one's body into an actual bird.
The hardest, most crucial step had been solved. Now it was only a matter of time.
Li Yao kept reading.
Kimura Takuya had created a clone identical to himself in every way.
It possessed his full memories and even thought with the same logic and awareness—it was a true clone.
It had the warmth and texture of human skin. Press an ear to its chest, and you could hear its real heartbeat. It even got excited when looking at a naked woman.
It breathed out real visible mist with every exhale.
It could feel pain.
It could perform every jutsu he could.
When the clone walked outside, no one could tell it apart from the original. Kimura even had it stroll past the Hyūga and Uchiha clan compounds—no one saw through it.
Not even the Byakugan or Sharingan could expose it. That alone proved it was a flawless clone.
From this perfect clone, he could now work toward a bird-form clone—and then to the full Perfect Transformation Technique.
The notes brimmed with Kimura Takuya's hope for success.
And Li Yao shared that same hope.
But when he turned the next page, he found only one bitter, self-mocking line:
"Heh… So that's it. What I called a perfect transformation is just the Shadow Clone Jutsu created long ago by Lord Tobirama."
What?
Li Yao's mind went blank, flooded with confusion.
Why say the technique doesn't exist all of a sudden?
Wasn't the previous page filled with optimism?
Why such despair on the next?
Li Yao flipped further ahead—nothing but blank pages. All the way to the end, there was nothing.
It was clear: Kimura Takuya had abandoned the research.
"But he already overcame the hardest part…"
"Why would he give up now?"
"Why?"
Li Yao furrowed his brows tightly, unable to make sense of it. He also felt a deep unwillingness.
The Perfect Transformation Technique was a life-saving jutsu—he needed it. How could Kimura give up so easily?
Li Yao went back to reread the final line:
"The perfect clone is the Shadow Clone?"
"What does that… hmm, wait."
Li Yao froze, then quickly flipped to the previous page and reread the description of the "perfect clone."
And then—his face went blank with realization.
It really did sound exactly like the Shadow Clone Jutsu created by Tobirama.
Li Yao recalled everything he knew about the Shadow Clone's effects:
A tangible clone, created by dividing one's chakra evenly.
It could think independently.
It could use all of the caster's jutsu.
Even the Byakugan couldn't see through it.
Even god-tier beings like Kaguya Ōtsutsuki couldn't see through it.
Every characteristic matched Kimura's so-called "perfect clone."
"This…" Li Yao was speechless. At last, he sighed, "As expected… In the world of Naruto, all forbidden techniques lead to Tobirama."
Though he couldn't know exactly how Kimura felt upon discovering that his great creation was merely a reinvention of the Shadow Clone Jutsu—
Li Yao could understand the despair.
It was like being an inventor, working tirelessly for years on what you believed to be a world-first innovation…
Only to be told someone else had already made it—and better.
That kind of soul-crushing realization was enough to make anyone give up.
Tobirama really was Tobirama.
So many of the ninja world's forbidden techniques could be traced back to him.
He was the first to develop space-time ninjutsu like Flying Thunder God—without a dōjutsu.
He was the first to create a technique like Edo Tensei that resurrected the dead—without the Rinnegan.
Shadow Clones, Exploding Tag Chains, Darkness Technique—all Tobirama's inventions.
In terms of forbidden jutsu, Tobirama was the unrivaled master.
Even Orochimaru, hailed as the most obsessive researcher of the ninja world, had spent his entire career feeding off Tobirama's legacy.
That alone showed how terrifying Tobirama's genius was.
Against such a towering figure in history, it was no wonder Kimura Takuya fell into despair.
Li Yao could understand.
But understanding didn't mean agreement.
Li Yao had no intention of giving up on the Perfect Transformation Technique.
He would continue the research.
Right now, his mind was already brimming with ideas and directions to explore.
Holding the notebook, Li Yao returned to his room, sat down, and began to jot down his own inspirations to continue the project later.
He picked up his pen and was just about to write—
When suddenly, a sharp pain shot through the back of his neck, like a bug bite. Instinctively, he reached back to slap it.
But before his hand made contact, a wave of dizziness struck him. With a thud, Li Yao's face slammed into the desk.
"What… the hell?"
That was the only thought that crossed his mind before he blacked out.
