Actually, it wasn't just Nagato who was looking for Obito; even Naruto was looking for Obito. He hadn't found Obito for a long time, so he caused trouble for Obito and then found an excuse to beat Obito.
Of course, Obito was unaware of Naruto's thoughts, but that didn't stop him from avoiding Naruto. Obito was prepared to lure Naruto in and then settle scores with him once he became stronger. If Obito knew Naruto's intentions, he would definitely disappear for a long time.
Naruto, do you have nothing better to do? Can't you find someone else to torment?
However, Naruto's plan was clearly going to fall through. He had searched for Obito for so long without finding him, which made Naruto somewhat bored. Who was he to be so terrifying as to avoid him like this?
However, what he didn't know was that not only Obito, but even Black Zetsu had disappeared. Due to a moment of carelessness, they were sucked into a strange portal of light and their whereabouts were unknown.
Naruto was still confused because he couldn't find Obito. After all, he had planned from the beginning to go find Obito whenever he had the chance, and then beat him up without saying a word. After all, killing him would be too easy for him.
The suspicious thing is that Naruto has been searching for a long time, but hasn't found a single clue. It's as if Obito suddenly disappeared from the Shinobi World; there's no trace of him at all. This is almost making Naruto question his existence. Where on Obito did that Obito guy go?
Naruto was puzzled, Naruto was confused. Naruto probably couldn't have imagined, even if he racked his brains, that Obito would go to another world. That's right, even Obito probably didn't know that the portal that sucked him and Black Zetsu in was actually a door to another world. If Naruto saw it, he would definitely recognize the portal, because it was just like the portal after clearing the Illusion Trial in the Hokage mobile game.
At this moment, Obito and Black Zetsu, who had been sucked into the portal, were lying on the ground like dead dogs. The surroundings were completely silent, so quiet that only the sound of the wind and Obito's faint breathing could be heard.
Obito, whose head was throbbing, was the first to wake up, but when he did, he was completely bewildered. What had he done to him?
"Ouch, my head hurts so much, where am I?"
Looking around, Obito was surprised to find that he didn't recognize any part of the Shinobi World he was in. Cold sweat broke out on his forehead. Yes, he was starting to panic because the place felt so desolate.
The surrounding environment was desolate and suffocating. Darkness, like a thick curtain, swallowed everything without a trace. Obito could see mounds of earth scattered on the ground, but more accurately, they looked like simple graves. Rusty longswords were stuck in the mounds from time to time, their blades broken and incomplete, as if they were the last blows left by their former masters in despair.
Every broken sword fragment seemed to whisper, recounting the past carnage and ruthlessness. The surrounding air was stagnant, filled with a chilling, murderous aura, as if a bloody battle had once taken place here, and the shadow of Shinigami had long since shrouded this land. The thick stench of blood, like a poisonous miasma that could never be dispelled, pressed down on every breath, every inch of skin, causing Obito's brows to furrow into a knot.
He couldn't help but search for Black Zetsu. If he remembered correctly, Black Zetsu seemed to have come here with him, but where was Black Zetsu?
Obito looked around and searched for a long time before finally spotting Black Zetsu. For some reason, Black Zetsu had completely turned into a lump of black mud, just like a black sludge, leaving Obito puzzled. What had happened to Black Zetsu?
He poked it with his finger, and a strange sensation lingered in Obito's mind. It was cold to the touch, like piercing a thin, slippery layer of grease with his finger. As his finger went deeper, it felt like sinking into a jar of thick oatmeal porridge that had cooled and begun to harden, mixed with a few grains of sand and plant debris.
This strange feeling intrigued Obito; he hadn't expected Black Zetsu's body to feel like this.
Just then, Black Zetsu woke up. As soon as he opened his eyes, he saw Obito poking him with his hand. Black Zetsu felt his anger rising. This kid was so rude.
"Hey, Obito, what are you doing?"
Obito was startled by the sudden sound. He hadn't expected Black Zetsu to wake up so suddenly. Imagine, a lump of black, sludge-like substance on the ground suddenly coming to life and yelling at you—wouldn't that be terrifying?
"No, it's nothing. Just checking to see if you're still alive."
Seemingly calmed down, Obito slowly explained his actions, but Black Zetsu Obito clearly wasn't going to buy it.
"Hmph, you better behave yourself, kid."
After Black Zetsu finished speaking, he also began to look around, but soon his eyes were filled with confusion, because he didn't even recognize where they had come to.
But what happened next was what truly terrified Black Zetsu. He had tried to transform from that lump of slime into human form, but after trying for a long time, he couldn't succeed. This made Black Zetsu somewhat panicked.
Obito could see that Black Zetsu was constantly changing his form, but he didn't know what he was doing and was a little confused about what was wrong with Black Zetsu.
"Hey, Black Zetsu, do you even know where you are? And what's wrong with you?"
Black Zetsu clearly didn't have time to pay attention to Obito. He just wanted to quickly return to human form because his current state was too inconvenient. He could only stay close to the ground, and he didn't want to keep looking up at people.
Unfortunately, he tried for a long time without success. But as they say, Black Zetsu is an old monster who has lived for so long. Although he could not transform into human form, he quickly calmed down.
"It seems this region is exerting pressure on me."
This is what Black Zetsu discovered, and even he doesn't know where he is. Does such a place really exist in the Shinobi World?
"Let's go, Obito, let's continue deeper and explore other areas."
Having no clue Obito could only listen to Black Zetsu, since there was no better way.
One person and one lump, and so they embarked on an exploration of another world, unaware of the dangers that awaited them ahead.
Meanwhile, in the Shinobi World, Naruto and Sasuke, with the help of Pakkun and other Shinobi World Ninja Dog, began searching for White Zetsu. Since they couldn't find Obito, surely they could find White Zetsu, and then use White Zetsu to find that guy Obito.
