Ninja school teacher, I can become stronger by teaching

“Why is my head so dizzy?”

As sunlight pierced through his eyelids, a subtle, prickling pain came from his back. Obito squinted and sat up from the grass.

His palm pressed against the ground, and the snapped grass roots made a crisp "pop" sound. The smell of grass around him rushed into Obito's nostrils.

“What the hell, wasn't I sleeping at home?”

Obito looked around at the incredibly empty surroundings with a dumbfounded expression.

He didn't have a habit of sleepwalking either, and this was sleepwalking way too far. Obito couldn't even see where his house was.

“Whatever, I'll find a place to eat first.”

Obito rubbed his stomach, feeling a bit hungry, and decided to eat before going home.

He patted the dirt and grass off his body, looked around, and realized that he was in a small park he had never been to before.

As Obito walked towards the exit, he passed a place with two swings.

There were four children there who looked to be about six or seven years old.

Obito's attention was drawn to one of the children with a head of dazzling blonde hair.

“Who would want to learn that kind of thing? You'll only get scolded.”

A slightly taller and thinner child looked up at the sky and said:

“Let's go home. Our families will worry if we don't go home soon.”

The other two children nodded in agreement and turned to leave with the tall, thin child.

“You'll regret not learning the skills of the great Naruto Uzumaki!”

Naruto continued to shout.

However, none of the three children looked back at him, and they walked away laughing and talking.

Naruto watched the three figures gradually move away, fell silent, and sat on the swing with a lonely expression.

He failed again. It really wasn't that easy to get recognition.

“Are you Naruto Uzumaki?”

“Eh?”

Naruto didn't notice Obito walking over. He was startled by the sudden voice of a stranger. If Obito hadn't caught him, he would have fallen to the ground.

“Looks like I'm already famous. I'm not far from getting everyone's approval.”

Naruto looked at Obito, realized that this was a stranger he had never seen before, and said smugly.

After confirming that he hadn't misheard, Obito fell into deep thought.

Unless he had slept for several years and during that time Minato and Kushina divorced, causing him to lose his memory and not remember him, and Naruto changed his last name.

Then he must have traveled to a parallel world he didn't know about.

“Who are you? Why are you spacing out?”

Naruto saw that Obito had inexplicably stopped talking and took the initiative to ask.

“Do you know Mugetsu Hanyu?”

Obito didn't answer Naruto's question, but asked him a question.

He believed that if it was Sage Mugetsu, even if it was a counterpart, he would definitely be an extremely reliable good person who could help him return to his original world.

“Mugetsu Hanyu? Who's that? Is he a very famous person?”

Naruto didn't mind Obito answering a question with a question, and asked blankly after thinking hard.

Obito put his right hand on his forehead, thinking that he was in trouble. He had not only traveled to a parallel world, but also one without Mugetsu.

“Maybe Teacher Mugetsu in this world is more low-key, and Naruto is young, so he doesn't know him.”

Obito still had a glimmer of hope in his heart.

If there was no Mugetsu, he really didn't know how to go back.

The Dragon Vein was a random mess, and it wasn't certain if he could even travel.

“It's so late, aren't you going home yet?”

Obito thought for a while and asked tentatively.

“It's the same whenever I go back, anyway, no one's waiting for me at home.”

Naruto replied with a nonchalant attitude.

Obito's heart sank to the bottom instantly. He had the Uzumaki surname and was an orphan. Wasn't this exactly the same as Naruto in parallel world number one?

Could it be "Obito" who did it again? Not this again.

“No, maybe this is the past of parallel world number one!”

Obito suddenly became excited.

If this was the past of parallel world number one, then Obito only needed to wait for ten years or so, and Mugetsu and the others would travel here to save the world.

At that time, he could ask Mugetsu to send him back to his own timeline.

“Big brother, why are you spacing out again? You're such a dork.”

Naruto couldn't help but complain when he saw Obito suddenly stop talking again.

“Is that so? I was going to say that I liked you, so I'd treat you to a bowl of Ichiraku ramen.”

Obito rubbed his chin and said with a regretful look.

“Ichiraku ramen!”

Naruto's eyes widened, and he hesitated.

“Haha, let's go, let's go eat ramen.”

Obito rubbed Naruto's little head and said with a laugh.

This was his little brother Naruto, he would treat him to a hundred bowls, not just one.

“But…”

Naruto looked at Obito embarrassedly. He had said bad things to Obito, but Obito was still treating him to food.

“No buts, let's go, I'm hungry if you're not.”

Obito didn't give Naruto a chance to refuse, and directly pulled Naruto to the Ichiraku ramen shop.

“Two large bowls of pork bone miso chashu ramen.”

Obito helped Naruto sit down and immediately shouted.

“Okay.”

Teuchi skillfully cooked the ramen and put it into the soup, and brought it to Obito and Naruto.

“Let's eat.”

Smelling the tempting aroma of the ramen, Naruto's eyes brightened, and he quickly picked up his chopsticks and started slurping.

Watching the eager Naruto, Obito smiled and started eating as well.

“Are you full? I'll order you another bowl if you're not full.”

Seeing Naruto eating, Obito put down his chopsticks and asked.

“No need, I'm already full, thank you for the ramen, big brother.”

Naruto showed a bright smile and waved his hand in refusal.

He was already content that someone was treating him.

“That'll be one hundred and fifty ryo.”

When Obito finished eating, Teuchi said with a smile.

“Okay.”

Obito responded and reached into his pocket. For him, one hundred and fifty ryo was nothing.

However, when his hand entered his pocket, Obito's expression changed slightly.

He thought of a very serious matter, he seemed to have no money.

Without considering whether the currencies were the same, he still had no money.

Before the time travel, Obito was doing hellish studies in order to become Hokage, so he was mostly wearing loose casual clothes at home, with nothing in them.

He even fell asleep without changing his clothes because he was too tired.

Obito had to be thankful for this, otherwise he would have traveled through time in his pajamas.

“Guest, you don't have any money, do you?”

Teuchi didn't know when he had walked to Obito's side, and put his hand on Obito's shoulder with a smile.

However, this smile was very terrifying in Naruto's eyes, causing Naruto to lean to the other side.

Obito wasn't flustered, and nodded calmly, “Yeah, no money.”

“Why do you look so confident when you don't have money?”

Naruto couldn't help but complain.

He thought it was a misunderstanding when he saw Obito looking so confident.

“Because I'm fast at washing dishes.”

Obito replied confidently. With his super physical fitness, washing one hundred and fifty ryo worth of dishes was easy.

If he used the Multiple Shadow Clone Technique again, washing one thousand five hundred ryo worth of dishes wouldn't be a problem.

Teuchi, Naruto: …

In the end, Obito's super dishwashing skills were not able to be displayed. Teuchi saw that Obito was a first-time offender, and didn't seem like the type to deliberately eat and run, so he let Obito go, and told him to pay together next time he ate.

“Big brother, why did you treat me to a meal when you didn't have any money?”

Naruto asked in confusion as they walked down the street.

“I forgot to bring money when I came out in a hurry.”

Obito scratched his head and explained.

In a sense, he really was in a hurry.

“You're too careless.”

Naruto complained.

“By the way, big brother, what's your name? I don't even know your name yet.”

“Call Kakashi an idiot.”

“Idiot big brother.”

“Damn it, that's not how you say it, you have to say the full name.”

“You clearly want me to curse, who would fall for that so obviously.”

After walking and talking together for half an hour, Obito said goodbye to Naruto.

Naruto was a little reluctant. There were too few people like Obito who didn't look at him with strange eyes and would even treat him to ramen. Naruto wanted to spend more time with Obito.

But Naruto also knew that Obito wasn't like him, who didn't have a home. He had to go back to his own home when it got dark.

“So what's your name, big brother?”

Naruto asked finally.

“I'll tell you next time we meet.”

Obito waved to Naruto and gradually disappeared before Naruto's eyes.

“If you don't want to say, then don't say it, I don't even want to know.”

Naruto pouted a little, a little unhappy, but quickly regained his smile.

“When I have money, I'll treat this idiot big brother to ramen.”

Naruto happily skipped back home.

On the other side, Obito pretended to walk a few streets before entering a secluded place, and then used the Transformation Technique to disguise himself and leave.

After confirming Naruto Uzumaki's identity in the park, Obito used his Observation Haki to detect two chakras hidden in the dark.

He guessed that these were Anbu responsible for monitoring Naruto, after all, Naruto was the Nine-Tailed Jinchuriki.

“I'm not wearing a forehead protector, and I haven't used ninjutsu, they shouldn't have noticed anything, right?”

Obito muttered a sentence and then became too lazy to care, and began to investigate the situation of the Uchiha clan, he wanted to obtain more information to determine whether this was the past of parallel world number one.

It didn't matter if he found anything unusual, what could a few Anbu do to him?

Obito's information about parallel world number one mainly came from Six Paths Obito's memory and Naruto's narration.

As far as Obito knew, the Uchiha clan in parallel world number one would be exterminated around the time Sasuke was seven years old because they wanted to stage a coup.

Although Obito had never seen Sasuke in this world, he had already seen Naruto. Naruto and Sasuke were born in the same year, just two months older.

If his guess was correct, then the current Uchiha clan was already on the verge of extermination, or maybe they had already been exterminated.

After all, the memory exchange caused by the chakra connection was only equivalent to watching a very long immersive movie. Obito couldn't remember everything, so he didn't know the exact date, just a rough idea.

Looking at the calm Uchiha clan grounds, Obito breathed a sigh of relief.

The night of the extermination had not yet come, he still had room to maneuver.

“If I change history, will Teacher Mugetsu and the others still travel to parallel world number one?”

Obito suddenly thought of a problem.

Mugetsu and the others traveled to parallel world number one because Naruto traveled there to ask for help.

But if Obito changed history, there might not be a Fourth Shinobi World War in the future, and Naruto might not come into contact with the Dragon Vein, causing him to travel to Mugetsu's world.

“Don't care about anything, hide in a corner for ten years and maybe I can go back.”

“But if I don't care about anything, Naruto, Sasuke, Nagato in this world…”

Obito fell into a dilemma. He realized that it was better to be stupid sometimes. If he hadn't thought of the possibility that this was the past of parallel world number one, he wouldn't have to worry about these things.

“Let's investigate the information first, anyway, it's all just speculation.”

Obito temporarily suppressed the distracting thoughts in his heart.

Currently, he had too little information. He wasn't even sure if there was a Mugetsu in this world, or if it was parallel world number one.
