Konoha: I have a clone in One Piece.

"Izuna?"

Sasuke Uchiha's face showed even deeper confusion.

"Sorry, I mistook you for someone else."

Madara Uchiha calmed his excited heart and answered as calmly as possible.

Uchiha Izuna was his younger brother, but he was killed by the Second Hokage, Tobirama Senju, long before Konoha was even established.

Although the little boy in front of him looks a lot like Izuna, he can't possibly be Izuna's younger brother.

"Alright." Sasuke Uchiha looked at the stranger standing not far away, who was about the same age as his brother, and asked curiously, "I haven't seen you in the village before. Are you from another village, here to participate in the Chunin Exams?"

"Well, I guess so."

Uchiha Dazzle nodded, then slowly walked to the lakeside, sat down beside Sasuke, and earnestly reminded him:

"Your training method is wrong."

"The hand seals for the Great Fireball Technique are 巳-未-申-亥-午-寅, but you paused for too long when forming the '亥' seal."

"Oh? Is that so?"

Sasuke Uchiha suddenly understood, and then looked at Madara Uchiha with gratitude on his face, saying:

"Thank you, I'll try again."

"Fire Release: Great Fireball Technique!"

"Fire Release: Great Fireball..."

After several hand seals were formed.

A fireball several meters long was successfully spewed from Uchiha Sasuke's mouth, and the scorching heat heated the lake water in the center to boiling point, causing a large amount of steam to rise from the lake surface.

"It's a success!"

Seeing the fireball he had just unleashed, Sasuke Uchiha's face was filled with joy.

Madara Uchiha smiled and praised:

"Not bad, it seems you have quite a bit of talent."

"Thank you, Onii-chan."

Sasuke Uchiha turned his little face to look at Madara Uchiha, and thanked him with gratitude.

Oh... Onii-chan?

Madara Uchiha was shocked, and his expression froze.

How long has it been?

After his last younger brother, Izuna, died, he never heard anyone call him so intimately again.

And now, the Uchiha boy in front of him, who looks almost exactly like his younger brother Izuna, is calling him Onii-chan?

Madara Uchiha felt a moment of dizziness in his eyes.

In that instant, looking at Uchiha Sasuke in front of him, he felt as if his beloved younger brother had been resurrected and was standing in front of him.

"...What did you call me?"

Madara Uchiha's voice trembled slightly.

"Onii-chan."

Uchiha Sasuke tilted his head cutely, his little face full of confusion, and answered:

"You're about the same age as my brother, and you even taught me ninjutsu. Can't I call you Onii-chan?"

"……Can't."

Madara Uchiha remained silent for a moment with a complex expression, then nodded affirmatively.

"Hehehe..."

Uchiha Sasuke chuckled foolishly.

For some reason, he felt a sense of closeness to this kind stranger in front of him.

Soon, Uchiha Sasuke was taught and trained by Uchiha Madara.

"Kid, that's how you throw a kunai!"

"Wow, that's amazing... Onii-chan!"

"The Uchiha clan's shuriken need to be used in conjunction with the Sharingan to reach their full potential, but there's actually a special training method before awakening the Sharingan. Watch closely, like this... and then like this..."

"Mmm, Onii-chan!"

"..."

With each "Onii-chan," Madara Uchiha's smile grew wider, and he became increasingly enthusiastic about teaching.

As the former head of the Uchiha clan, Madara was extremely proficient in the various techniques and training methods of the Uchiha clan.

Even someone as clumsy as Kenji Uchiha Obito could have his strength greatly improved in just a few months, let alone Uchiha Sasuke.

Sasuke's talent needs no further explanation.

As the reincarnation of Indra after Madara, Sasuke is an extremely talented genius in all aspects, including ninjutsu and taijutsu!

The experience of teaching a bright student is completely different from that of teaching a slow learner.

Obito Uchiha once nearly infuriated Madara Uchiha, but looking at Sasuke now, Madara's eyes gradually revealed a look of appreciation.

……

……

at the same time.

Inside a training ground in the Forest of Death, in Konoha Village.

Vast swathes of lush green trees were burned by the raging fire, their trunks pierced by sharp kunai.

The two figures collided at an extremely high speed.

"Fire Release: Great Fireball Technique!"

A blazing fireball shot out from Itachi Uchiha's mouth and flew straight toward Kakashi Hatake, who was in mid-air.

But that was just a shadow clone.

As the white mist appeared, Itachi Uchiha's heart tightened, and he immediately jumped up.

In an instant, the ground where he was standing had turned into a swamp, and a pair of mud-covered hands even emerged from the swamp.

Just as Itachi Uchiha drew his shuriken from his waist, preparing to shoot it at those mud-covered hands...

He suddenly stopped moving and frowned.

For some reason, in that instant, he felt as if he had lost something important, and a deep unease settled in his heart, but he couldn't quite remember what it was.

Take this opportunity.

Kakashi Hatake swiftly circled behind Itachi and hung a sharp kunai around Itachi's neck, subduing the genius who was several years younger than him.

"Wow, that's really impressive."

Kakashi Hatake put away his kunai, clicked his tongue in admiration, and then asked with a hint of doubt on his face:

"What were you doing just now?"

Uchiha Itachi snapped out of his daze and quickly bowed politely to express his apology:

"Uh...sorry, Kakashi-senpai, I was daydreaming."

"It's okay, it's okay. If you hadn't been distracted, I wouldn't know how I would have beaten you."

Kakashi Hatake quickly waved his hand.

"No, even if I don't get distracted, I still absolutely cannot beat you, Kakashi-senpai."

Itachi Uchiha looked at Kakashi Hatake with gratitude and respect.

"Hahaha... Let's stop flattering each other." Kakashi Hatake took a few steps back with a serious expression, then said in a deep voice, "Let's continue."

"OK."

……

……

Happy times are always fleeting.

Sasuke Uchiha glanced at the sky, watching the sun completely set, and immediately stopped training. He raised his hand and shouted to Madara Uchiha, who was still full of enthusiasm:

"Onii-chan, I'm going home~"

"Okay, sure."

Madara Uchiha glanced at the gradually darkening environment and nodded.

"Thank you, Onii-chan. If it weren't for your guidance, I probably wouldn't have made much progress even if I practiced until dark."

Sasuke Uchiha bowed deeply to Madara in respect.

Then, as he turned to leave, Uchiha Sasuke suddenly looked back, his cute big eyes showing a hint of confusion as he asked:

"Onii-chan, my name is Sasuke, Uchiha Sasuke. What's your name?"

"Me..."

Madara Uchiha pondered for a moment, then crossed his arms and replied in a deep voice:

"Luo, Otsutsuki Luo." (End of Chapter)
