The Substitute

Uchiha Dan is a transmigrator.

It is a bit embarrassing to say.

In his previous life, he was a fanatical bodybuilding enthusiast and a "god-tier" figure in the circle, but after a high-intensity workout session where he challenged his limits, he died suddenly from heart failure.

When death arrived, Dan felt no regret, only a sorrowful and unwilling realization:

The capabilities of human beings, after all, have their limits.

Unexpectedly.

After death, Dan transmigrated into the world of Naruto and was reborn as a member of the Uchiha clan, becoming the younger brother of Uchiha Mikoto.

Having some knowledge of the Naruto plot, he knew from a young age:

He would have a brother-in-law named Fugaku, who was the Clan Head of the Uchiha. He would also have two genius nephews, named Itachi and Sasuke.

The Uchiha are the most prominent ninja clan in Konohagakure.

Fugaku's family, furthermore, are the core figures of the Uchiha.

However.

Dan felt nothing in his inner heart regarding his background; what truly made his soul tremble with excitement was something else entirely.

That is.

Humans in this world have 130 trillion cells in their bodies, three times that of humans on Earth, and through training, they can refine Chakra from within those cells to further strengthen themselves.

The strong can fly through the sky, burrow into the earth, move mountains, and drain seas.

There are no limits.

Uchiha Dan therefore firmly believes that this must be a second chance at life bestowed upon him by the great Muscle God from the heavens.

So.

He embarked on the path of bodybuilding training in his second life without hesitation.

It is worth mentioning.

Although Dan pursues strength and yearns to be powerful, he has absolutely no interest in becoming a Konohagakure ninja.

Because he knows.

Konohagakure is a military organization with a terrifying nature, one that even trains children only a few years old into weapons of war and sends them to the front lines.

The Will of Fire? Don't make me laugh.

Dan has no sense of belonging to Konohagakure, and it is impossible for him to risk his life on the battlefield for such a village.

Thus.

At the age of 6, he made his choice: relying on the strong body he had developed since childhood, he found a random excuse and pinned the tall, burly Chunin Teacher from the ninja academy to the ground, beating him up.

Dan lost his eligibility to become a ninja, but he also avoided the fate of going to the battlefield.

Since then.

He has immersed himself in his own world, living a life of training away from worldly disputes, until the blink of an eye brought him to his second zodiac year.

Then, something unexpected happened.

Half a month ago, when Dan finished his day's training and pushed his physical body to a new peak, he...

Awakened a Stand.

After 24 years of transmigrating, he finally waited for his long-overdue "cheat."

He turned off the showerhead and wiped his body dry with a towel.

Dan turned to the side and, through the mirror, saw the star-shaped mark on his left shoulder.

He had known about this birthmark since he was a child, but he never paid it any mind until he awakened the Stand "The World" and finally remembered.

This is the ancestral birthmark of the Joestar family from the JoJo series of manga.

The World is the Stand awakened by the great villain Dio after he forcibly took over the body of Jonathan Joestar.

So.

The Muscle God had left him a revelation long ago.

With a clatter.

Dan pushed open the bathroom door, changed into a loose black kimono, and walked straight into the kitchen.

He opened the refrigerator and found that there weren't many ingredients left.

He replenished some fast-acting carbohydrates and vegetables, ate 20 egg whites, and finally drank a bottle of Chicken Breast Juice.

"I'm sorry, Gym Director, I'll go out and buy groceries right away."

Samui walked over, bowed to Dan, and said with an apologetic look on her face.

In addition to serving as the receptionist, she is also half a nanny to Dan, usually responsible for laundry, sweeping, and buying groceries and cooking.

However, Dan's appetite is so massive that sometimes, if Samui isn't paying attention, she finds the refrigerator completely emptied.

"I'll go with you; it's a good chance to buy some extra beef today," Dan said.

And so.

The two locked the door of the Gym, walked out of the Alley together, and headed toward the market.

Uchiha Itachi looked pale as he walked along the streets of Konohagakure.

He could feel the gazes of many passersby on him; the looks they cast his way held curiosity, but far more were filled with disgust and fear.

As for the reason, it was the Uchiha fan crest on his back.

Ever since the Nine-Tails' Attack several years ago, the hostility of the villagers toward the Uchiha Clan had grown increasingly intense.

And the Uchiha Clan, under the suppression of the Konoha high command, had been forced to relocate to the Village Outskirts, becoming completely isolated.

Usually, Itachi spent every waking second contemplating the issues between his clan and the village, but today, as he walked, the person he frowned and thought about was his Uncle, Uchiha Dan.

Before he knew it, he had returned home.

"Brother!"

Sasuke, who had been playing in the courtyard, immediately ran over on his short legs as he always did, throwing himself into Itachi's arms.

"Hiss." Itachi couldn't help but gasp, feeling a spasm in his abdomen.

"Brother, what's wrong?" Sasuke noticed Itachi's unusual reaction and couldn't help but look up, asking with a curious face.

"I'm fine, Sasuke."

Itachi endured the pain and forced a smile, then patted his younger brother's head and took his small hand to head into the house.

In the dining room.

Uchiha Mikoto, wearing a beige apron with her long black hair tied back, was busy placing the carefully prepared meal onto the table.

"Itachi, you're back."

Seeing her eldest son return, a smile appeared on Mikoto's face, and she immediately asked, "Where is your Uncle?"

"Sorry, Mother, Uncle... he had something come up, so he probably won't be able to make it."

Itachi hesitated in his Inner Heart; he didn't tell his mother the truth, instead weaving a white lie.

After all, if his mother knew that Dan felt her cooking wasn't to his taste, she would surely be saddened.

"If he can't come, then we won't wait for him."

A deep, magnetic voice sounded as Uchiha Fugaku walked out of the study, waving his hand to signal the start of dinner.

And so.

The family of four sat around the dining table.

At the table, there was complete silence.

Do not speak while eating, do not speak while sleeping; this was the family rule.

Itachi took a few bites of food, chewing while looking at his family before him.

His father was dignified and upright, his mother gentle and virtuous, and his younger brother innocent and cute—truly an enviable, perfect family.

Unfortunately.

The only flaw was that he and Sasuke had an eccentric, peculiar Uncle.

Whenever he thought of Uchiha Dan, Itachi lost even the appetite to eat.

"I'm full."

He put down his chopsticks, stood up, and bowed to his parents. "Father, Mother. I'm a bit tired, so I'll return to my room to rest."

With that, he left the table under the surprised gazes of Fugaku and his wife.

"Was the food not good today?"

Mikoto murmured, thinking her cooking had been rejected by her eldest son, but she glanced at her younger son, Sasuke, who was eating happily like a little pig.

Fugaku also frowned slightly, feeling that Itachi was a bit strange today, not quite like his usual self.

Could it be that he wasn't adjusting well to having just joined the Anbu?

Thinking of this, he decided to find a time to have a good talk with his son and fulfill his responsibilities as a father.

"Creak."

Itachi gently closed his bedroom door.

He took off his shirt, revealing a large bruise on his lower abdomen, clearly caused by a Fist, which was still stinging with pain.

After applying medicine to the bruise, he lay on the bed and slowly closed his eyes.

Itachi replayed in his mind over and over how he had been defeated by Uchiha Dan, yet he could not fathom the reason.

As it turned out.

He didn't understand his Uncle at all.

Perhaps I could ask Shisui about my Uncle.

"I'll take this cow."

Uchiha Dan pointed at a yellow ox weighing over five hundred kilograms in the pen and said to the vendor, "Same as usual, please slaughter it and have the beef delivered to my Gym."

"Yes, of course!"

The vendor replied hurriedly, beaming with joy.

While others bought beef by the catty, this Mr. Dan bought it by the head. Furthermore, he bought three to five cows a month, making him a major client.

Other customers at the market couldn't help but whisper behind Dan's back after witnessing this scene:

"No wonder he's built so strongly; I bet this guy eats beef like it's his staple food."

"That physique is terrifying. Just standing in front of him makes it hard for me to breathe."

"But that woman beside him is so beautiful. Just like Lady Tsunade, she's not only blonde but also has a huge chest."

"..."

Samui shook her head slightly.

If these customers knew that the Gym Director ate over a dozen meals a day at his peak and had to go to the bathroom every hour, their jaws would probably hit the floor.

That should be enough.

Dan and Samui walked out of the market. Besides the beef, the two had also bought a large amount of vegetables, dairy products, and eggs, filling several large bags to the brim.

"Whew~"

Samui panted and shrugged her shoulders, feeling a soreness in them.

It wasn't just because she was carrying two large bags of groceries; a more significant reason was that her chest was getting bigger and bigger.

As she grew older, at just nineteen years old, her chest had developed to an exaggerated degree, one that couldn't be hidden even with loose clothing.

She had felt many strange gazes from men while walking down the street lately. Fortunately, she had the "colossus" that was Dan walking beside her; otherwise, men would have swarmed her to strike up a conversation long ago.

Sigh, why must I bear such a burden?

Samui looked down and couldn't even see her own toes, sighing to herself in distress.

"Give it to me."

Noticing the sweat beading on her forehead, Dan reached out to take one of the bags, relieving much of the burden for Samui.

"Thank you, Gym Director."

Samui's face flushed slightly as she spoke softly. That shy and lovely appearance would stir a strong sense of protectiveness in any man who saw it.

On the surface, it seemed she was interested in Dan.

The truth was.

She was intentionally feigning affection for Dan to hide her identity as a spy, hoping to lull the man into a false sense of security.

Unfortunately, faced with Samui's allure, Uchiha Dan remained completely unmoved and never took the bait.

This left Samui with a sense of frustration, leading her to doubt her own charm at one point.

But later, she finally realized the truth. The problem likely didn't lie with her.

It lay with Dan.

This man had nothing but muscles in his head and no room for women.
