UK:GSW Chapter 414 – Black Zetsu's Secrets Exposed, Resolved with the Most Classic Political Strategy
When the Kage of the Five Great Villages in World No. 2 headed toward the Land of Iron to attend a Five Kage Summit destined to be anything but ordinary, in the Main World, research on World No. 2's Black Zetsu had already reached a decisive breakthrough.
In other words, Orochimaru and the others had found a way to control Black Zetsu!
Black Zetsu was an extremely strange existence, but at its core, it was still a creation of Yin–Yang Release. Even if World No. 2 were somehow to connect to the Boruto era, the most that version of Black Zetsu could add would be a so-called "god technique" attribute.
Although such things might sound mysterious, to scientists, once the principles were understood, a path for research and countermeasures naturally appeared.
And with the Spiritual Network World as their ultimate research and simulation weapon, their progress was even greater—almost absurdly so.
After all, they could even manipulate the flow of time inside it.
As a result, in just half a month after Black Zetsu's capture, they developed a method to control him.
This method didn't simply immobilize him; it could also force him to perform certain actions and make him divulge everything he knew involuntarily.
Interrogation and intelligence extraction methods of this sort had long existed in the ninja world, but they were only effective on humans. None of them worked on Black Zetsu—until now.
Once the scientists understood his composition and developed their control method, the results were even better than with human targets.
Humans could have mental seals, so a slight misstep might kill the subject and make all their memories irretrievable.
Even without seals, a sufficiently strong will could resist the process, making it difficult or dangerous to use. Forcibly applying it could burn out the brain, rendering the search useless.
But Black Zetsu was different. As a creation of Kaguya Ōtsutsuki, his vitality was absurd. Rough methods wouldn't kill him—if anything, they would make him more alert.
Thus, they didn't have to be cautious in dealing with him. Not to the extent of carelessness, of course—they couldn't let him escape—but there was no need to worry about his life.
The moment the control device was deployed, World No. 2's Black Zetsu experienced unprecedented torment. The instrument wrapped around him without mercy, delivering a soul-rending pain that left his amorphous body twisting and losing its shape, his screams echoing in agony.
Meanwhile, the device was also analyzing and forcibly rewriting his structure—breaking him down as a Yin–Yang Release and god-technique construct, then seizing control of him entirely.
There was not a shred of humanity in this process; he was treated as something that couldn't die and thus could be exploited to the fullest.
Uchiha Kei thought to himself that, had he encountered something like this before his transmigration, countless self-righteous do-gooders would be loudly protesting the "abuse of living beings."
In the future, if the ninja world developed along the lines planned by him and Minato, moral standards would inevitably rise, and so-called "bleeding-heart liberals" would emerge.
But that was for later—and Kei had no intention of letting such people dominate the discourse.
For now, his only thought was that Black Zetsu deserved every bit of this.
Given all the atrocities he had committed—no matter which version of Black Zetsu—he carried countless sins and grudges, the kind of super-war criminal who deserved to die tens of thousands of times over.
Kei had always felt that Black Zetsu's ending in the original story was far too lenient. Being sealed with his "mother," Kaguya Ōtsutsuki, was practically a reward. A creature like him should be subjected to the cruelest torment imaginable and milked for every bit of value he could provide—eternal suffering for eternal crimes.
Some people excused Black Zetsu by calling him a "mama's boy" who only wanted to save his mother, arguing that such a person didn't deserve torture—just a swift death. Kei utterly rejected that notion.
Those guilty of grave atrocities deserved to be met with the harshest justice, to honor their victims.
So, watching Black Zetsu's current misery, Kei was more than pleased—he wanted to see the screws tightened even further.
Piece by piece, everything Black Zetsu knew, everything he had done, came to light. Orochimaru and his team recorded it all in real-time through the genjutsu-linked network.
They soon discovered just how deeply he had been the shadowy hand behind history—at least in World No. 2. Many disasters in ninja history, countless instances of brothers turning against each other, and centuries-long clan feuds had been orchestrated by Black Zetsu.
For example, the millennia-old feud between the Uchiha and Senju clans began with their progenitors, Indra and Asura, turning from brothers into mortal enemies. While part of that stemmed from the Sage of Six Paths' skewed values and unfair treatment of his sons, Black Zetsu had also been there in the shadows, quietly pushing Indra toward darkness.
From Black Zetsu's memories, Orochimaru's team confirmed the Sage of Six Paths' existence. Through forced memory extraction, they could even witness the images in Black Zetsu's mind—glimpses of the ninja world a thousand years ago.
Back then, the world was much the same in terms of nations, but before the Sage spread chakra, there were few superhuman warriors. Wars between nations were fought mostly by ordinary soldiers. Some individuals used supernatural power, but it came from the world's native "Senjutsu" alone—not chakra—and was far weaker than later eras.
Once the Sage of Six Paths shared chakra with his followers, the number of superhumans exploded. The ninja world rapidly evolved into an age of wars between superhuman shinobi, and the Sage's followers and descendants became the founders of the earliest ninja clans.
The Sage's two sons, Indra and Asura, then began their thousand-year cycle of enmity. Even in death, their chakra reincarnated endlessly, perpetuating their struggle.
Through Black Zetsu's eyes, they saw each generation of Indra's and Asura's reincarnations—among them Hashirama Senju and Madara Uchiha.
What shocked them was that, in most generations, Indra's reincarnation was slightly stronger. Asura's reincarnation could keep up but never surpass him, except perhaps in the late stages of their rivalry when they were evenly matched.
Sometimes, either reincarnation would die prematurely—after all, in a millennium of endless war, no one was guaranteed survival, not even them. But whenever one fell, the other would soon follow, and the cycle continued.
The sole exception was the Hashirama–Madara generation.
Not only did they die far apart in time, but their strength was completely reversed—Madara was the one constantly suppressed.
It was as if Hashirama had some kind of hidden "growth multiplier" system—whenever Madara grew stronger, Hashirama's power would rise by 1.25 times that amount, ensuring he always stayed ahead.
This imbalance only ended when Hashirama "died young" from the aftereffects of the Valley of the End battle. Madara, still clinging to his dream of world peace, slowly integrated Hashirama's cells and eventually awakened the Rinnegan near the end of his life.
And here came the part that Tobirama Senju wanted to laugh about endlessly—Madara's Moon's Eye Plan was entirely Black Zetsu's scheme. The Uchiha clan's ancestral stone tablet really was left by the Sage, but Black Zetsu had altered it, turning a warning about a dangerous progenitor sealed on the moon into an endorsement of the Moon's Eye Plan as the key to peace.
In other words, Madara had been conned.
Kei had already revealed this much before, using White Zetsu as proof, but until now, they hadn't known the fine details.
Now that the full truth was out, Tobirama could hardly contain his glee. From his perspective, it was the funniest thing in the world—Madara, played like a fiddle for decades.
If he could, Tobirama would mock Madara for this for the rest of his life. And since they were now both Heroic Spirits with uncertain lifespans, that might actually be possible.
The others didn't share Tobirama's schadenfreude. Orochimaru's group felt it was tragic, even sigh-worthy. Madara was a legendary figure, an undisputed titan of the ninja world. To see such a man not just fooled but utterly manipulated… it was almost pitiable.
Black Zetsu had claimed to be Madara's will made manifest, and Madara believed him without question—never probing, never testing, taking every word as truth.
It was partly because he had just awakened the Rinnegan and didn't yet fully grasp its abilities, but mostly it was his arrogance and overconfidence.
Black Zetsu had exploited that weakness perfectly.
Without the interference of the Main World, Black Zetsu's plan might have succeeded—perhaps more smoothly than ever before.
In World No. 2's timeline and environment, had the Main World not acted, Black Zetsu could have freed his mother, Kaguya Ōtsutsuki, at last—fulfilling his millennium-long objective.
In truth, his so-called "thousand-year plan" wasn't much of a plan at all. It was just a thousand years of being a professional troublemaker—ensuring that peace never took root. Whenever calm loomed, he would stir up hatred and hostility until war resumed.
His "rescue plan" for his mother was nothing more than waiting—waiting for someone capable of awakening the Rinnegan.
Madara was the only one in a millennium with both the potential and the drive, so Black Zetsu fixated on him, guiding him to discover the altered stone tablet, learn how to awaken the Rinnegan, and eventually achieve it.
His methods weren't particularly sophisticated—just the classic advantage of plotting against someone who wasn't plotting back.
In truth, the simpler the scheme, the more likely it was to succeed.
Black Zetsu's approach was like the most traditional, time-honored political ploy: "invite someone to a meeting, then treat them to dinner."
Simple. Effective.
In the end, all of Black Zetsu's machinations and secrets were laid bare and recorded.
And there was more than just information—he had also amassed many treasures over the centuries, all carefully hidden. Now they would belong to Main World Konoha.
Of course, Konoha wouldn't keep them all; some would be shared with World No. 2's Konoha.
And this was only World No. 2's Black Zetsu. The Main World's Black Zetsu was still at large—but now Kei's side had the means to capture him.
All that remained was to deal with Madara first. Once Madara understood the truth, they could guarantee Black Zetsu's downfall.
Their plan was to use the most classic, most reliable political tactic: lure Black Zetsu into a trap—and kill him.
