Frightened Black Zetsu: Could This Guy Be an Ōtsutsuki?

Deep within the dark and damp underground karst cave. With no sunlight touching it year-round, only a few clusters of eerie green chakra flames flickered on the stone walls, casting wildly distorted shadows around them. Black Zetsu's pitch-black half was leaning listlessly against the massive toe of the Demonic Statue of the Outer Path. It was waiting. It was waiting for Obito to drag that blonde brat back. As long as they got their hands on the Nine-Tails, the hardest nut to crack in the Eye of the Moon Plan would be broken. As for that variable named Uchiha Yoru in Iwagakure, once the Ten-Tails was resurrected, they would all be mere trash. Pop. The soil on the ground boiled like boiling water. White Zetsu's pale half-face drilled out, wearing its signature mindless smile. "Why has Obito been gone for so long?" White Zetsu shook the pitcher plant leaves on top of its head, its tone leaking a hint of boredom. "Dealing with a four-year-old brat, surely he doesn't need to change his diapers for him personally, does he?" "Shut up." Black Zetsu didn't even lift an eyelid, its voice as cold as ice shards. "Obito is wearing Madara's name right now, he knows what he's doing." However, the moment its voice fell. "Hum—!" The air in the center of the cave suddenly twisted without warning! The distortion was extremely violent, like a torn cloth bag being forcefully ripped open by someone, making a harsh, tearing sound. "Is he back?" White Zetsu curiously poked out half its body. The next second. "Bang!" A mass exuding a thick stench of blood was violently slammed out from that heavily shrunken Kamui spatial tear. It rolled seven or eight times across the hard rocky ground, leaving a shocking trail of blood behind. That could hardly be called a complete person. The right half of the White Zetsu tissue had already been minced into a messy pulp, pale shredded flesh mixed with blood plastered all over the ground in a sticky mess. The left half of the body was equally horrifying. At the neck was a fatal slash that almost severed the trachea, frantically spurting out bloody foam. That signature orange swirl mask was long gone. It exposed Obito's scar-covered face, distorted to the absolute extreme. His left eye was tightly shut, the corner of the eye still bearing traces of dried bloody tears, clearly ruined. "Obito?!" Black Zetsu and White Zetsu simultaneously gasped, their eyeballs popping out. This was nothing like going to catch a brat. This looked more like he had just crawled out of the meat grinder of the eighteenth layer of hell! "Save... save me..." Obito convulsed violently in the pool of blood like a dying wild dog. That sole remaining right eye stared fixedly at Black Zetsu, its pupil full of lingering horror and despair. Black Zetsu's asphalt-like body slid over instantly. It pressed a hand onto Obito's battered torso, frantically injecting its own Yin-Yang Release chakra into him to forcefully keep his last breath from fading. "What on earth happened?!" Black Zetsu's voice went out of tune, sharp enough to sound like fingernails scratching a chalkboard. "You went to the back mountains of Stone Village, how did you get beaten into this ghost of a state?!" Obito coughed up large mouthfuls of blood clots, his throat making a wheezing sound like a broken bellows. "Intel... it was all fake..." He grabbed Black Zetsu's arm tightly, his fingernails almost digging into that mass of black mud. "A trap... This is a dead end specifically waiting for me to jump into!" "Who did it? Ōnoki? Or the Stone Village's Demolition Corps?" White Zetsu hopped up and down anxiously on the side. "It's Minato Namikaze..." Obito gritted his teeth, every single word accompanied by heart-piercing agony. "He's not dead! Not only is he not dead... his strength is even more terrifying than on the night of the Nine-Tails' Attack!" The cave instantly plunged into a dead silence. Black Zetsu's yellow eyes widened abruptly, flashing with incredulous light. Minato wasn't dead?! Back then, it had watched with its own eyes as Minato executed the Reaper Death Seal! Even the Death God's sickle had sliced down, how could he possibly still be alive? And on top of that, he was running around acting as hired muscle for Stone Village?! "Even if Minato isn't dead, you couldn't beat him, but couldn't you run away?" Black Zetsu forcefully suppressed the shock in its heart, demanding harshly. "What about your Kamui? That's a one-of-a-kind Space-Time Ninjutsu, not even Minato's Flying Thunder God should be able to stop you from shifting into intangibility!" Hearing the word "Kamui". Obito's body shook even more violently, just as if he were recalling some extremely terrifying nightmare. "Useless... completely useless..." A hint of a sob carried into Obito's voice, a kind of collapse where one's faith was thoroughly shattered. "It's Uchiha Yoru..." "He didn't even weave seals, he just glanced at me..." "The space around me was forcefully frozen!" Obito's breathing grew rapid, his hands scratching wildly in the empty air. "Intangibility was interrupted... it was like being welded in place!" "If I hadn't kept a backup plan, rewriting reality with Izanagi, what you'd be looking at right now would be a corpse!" Boom—! This sentence fell like a thunderbolt from the nine heavens, directly splitting Black Zetsu's crown. Black Zetsu froze in place, the hand pressing down on Obito trembling slightly. Space freeze? Based purely on a single glance, it forcefully locked down the Mangekyō Sharingan's Kamui?! What the hell kind of concept was this? You had to know that Space-Time Ninjutsu was the absolute highest-tier application of laws in the Shinobi World. Even Madara Uchiha at his peak back then could only choose to endure it head-on or dodge when facing such an overbearing cross-dimensional transfer as Kamui. Achieving a forcible cutoff from the root was an absolute impossibility! Unless... the other party's attainments in the laws of space and time far surpassed Obito! "This is impossible!" Black Zetsu leaped up abruptly, pacing frantically back and forth in the cave like a headless fly. Its brain, which had lain dormant for a thousand years, was operating at over-capacity right now. Something was wrong. Way too wrong! Black Zetsu recalled all sorts of twists and turns that had occurred in the Shinobi World recently. All the clues, interwoven like a spiderweb, ultimately converged upon that single name. Uchiha Yoru. Before the Nine-Tails' Attack, this guy was totally a nobody whose chakra records didn't even exist. Yet that night, not only did he save the doomed Minato. He also suppressed the Nine-Tails' chakra until it was docile and obedient. And now, he had actually displayed terrifying power capable of casually crushing the laws of space! Black Zetsu had lived for a thousand years. It had witnessed the Sage of Six Paths' creation-grade might, and the fated battle between Ashura and Indra. It understood the power system of the Shinobi World far too well. The ceiling of chakra was locked. Mortals—even mortals who had awakened the Rinnegan—still had to abide by causality and laws. Being able to simultaneously foresee the future, lay precise ambushes, suppress Tailed Beasts, and even casually freeze space... This was fundamentally not a method a shinobi could possess! This attitude of treating rules as nothing and looking down on everything from on high... Black Zetsu's footsteps came to an abrupt halt. A fine layer of ripples spread across the surface of its pitch-black body. Just as if its disguised skin had been pierced by some extreme terror. A non-existent cold sweat slowly trickled down Black Zetsu's forehead. An extremely absurd yet logically perfect closed-loop guess grew wildly in its mind like toxic weeds. Its pupils shrank to the size of pinpricks, staring fixedly at the pitch-black rock wall above. "This Uchiha Yoru..." Black Zetsu swallowed hard, only feeling a creeping horror. "Could he actually be... some old Ōtsutsuki ancestor reincarnated, specifically running to the Shinobi World to crash the party?!"
