Metal Skeleton

"Konoha's environment is truly wonderful, surrounded by trees everywhere," Yu marveled. In the manga, only Konoha's natural environment was top-tier, far surpassing the other ninja villages, especially the harsh, sandy Sunagakure.

He had originally intended to return to his own class, but his eyes caught a swing set in the woods.

Yu's playful side surged, and he sat on the swing, pushing himself higher. This was a rare moment of joy. Although he no longer had his phone or computer, he felt that his current life suited him better.

"I wish I didn't know about the future."

If you know what's going to happen, you can't be content with the present.

He understood clearly that in the world of Naruto, only strength could protect him. He didn't want to become cannon fodder for those who impulsively wanted to change the world.

No matter what, he wanted to control his own destiny. Why should others do whatever they pleased?

And to control his own destiny, he needed strength. Only strength could break through all barriers and difficulties.

The higher he swung, the happier Yu felt. Today, he had found a way to solve his Chakra problem, bringing him one step closer to being invincible.

"Naruto, no matter how much you run, it's useless. I'm determined to have your bloodline," Yu thought to himself.

Since ninjutsu training was still ongoing, Yu was the only one in the entire forest. At this moment, Yu was having a great time, but others might see it differently.

After Yu left, Naruto thought for a moment, then quietly followed him.

Naruto was hiding at the edge of the woods, secretly watching Yu.

In the silent forest, Yu was the only one swinging. Wasn't this a scene Naruto often experienced? Loneliness, desolation, having to spend time alone.

Upon seeing this scene, Naruto finally believed that what Yu had told him was true. He had truly misunderstood Yu's sincere intentions.

After an internal struggle, Naruto made up his mind and emerged from his hiding spot. He didn't want to miss out on a friend.

"I'm sorry!"

Naruto apologized to Yu.

Seeing this, Yu was naturally very pleased. He had thought his plan had failed today, but Naruto had come to him on his own.

Things that come to you shouldn't be refused.

So Yu asked, "Will you be my friend?"

Naruto nodded without hesitation.

"Yeah!"

A smile bloomed on Naruto's face. This was his first friend.

"Uchiha Yu."

"Uzumaki Naruto."

The two small hands clasped together.

Of course, Naruto didn't know Yu had other intentions. But that didn't stop them from becoming friends. Yu had his own selfish motives, but he was also very happy to be friends with Naruto, after all, Naruto was a golden thigh.

Next, the two played on the swings in the forest. While it seemed childish, what else could two eight-year-olds do? Even if they talked, what could they say?

Yu treated it as playing with a younger brother. As a child with an adult's soul, he also had to possess the noble qualities of respecting the old and caring for the young.

The happy times quickly passed, and the bond between Yu and Naruto grew significantly.

"See you tomorrow!"

"See you tomorrow!"

Yu and Naruto parted ways on the playground, both with smiles on their faces.

Naruto's smile was naturally due to gaining a friend and ending his lonely existence, while Yu's smile had many facets, which wouldn't be elaborated on here.

After school, Sasuke was waiting for Yu to go home together. During dinner, Sasuke noticed Yu was in a good mood and asked, "Did something happy happen today?"

Yu thought for a moment and said, "Today I saw Sasuke-bro's fight. That senior is going to be a genin next year. Sasuke-bro, you're amazing."

No one dislikes praise, especially from someone they care about.

However, Sasuke's smile lasted only a few seconds before chilling. He thought of Itachi. The gap in their abilities was still vast, and he had a long way to go to achieve his lifelong dream. He couldn't be happy over a small improvement.

Yu naturally noticed Sasuke's change. Uchiha Itachi was Sasuke's greatest inner demon, and even he couldn't change that.

So he quickly changed the subject.

"Today I made a new friend, and he's in your class. His name is Uzumaki Naruto."

"Uzumaki Naruto? How did you get to know that guy?" Sasuke naturally knew about the dead last in their class, the two positions that garnered the most attention being first place and last place.

"We met on the playground. I feel like he's very similar to me..." Yu trailed off, lowering his head.

The atmosphere became somewhat heavy.

"Although that guy can be a bit unreliable, he's not bad as a friend. But you can't mess around with him. Don't slack off during training. We'll go practice the Three Body Technique together later," Sasuke said.

Yu smiled and replied, "Okay."

Yu felt that Sasuke was becoming more and more like an older brother. This feeling of being cared for by someone was quite nice.

"Is this considered a bond!"

The word "bond" gave Yu goosebumps. In his previous life, he had often joked about "Naruto" and "Sasuke's" bond.

After finishing his training, the butler Yunshang Jinwei brought the two brothers a medicinal soup. High-intensity training requires various energy supplements; otherwise, it's easy to sustain hidden injuries. The medicinal soup was specially made to replenish stamina and heal bone and muscle damage.

Back in his room, Yu sat cross-legged on the bed and began to refine his Chakra. Mental energy and physical strength intertwined to form Chakra. Although he could only increase it a little each time, at least he could see hope.

His current Chakra level was less than one-fifth of that of a normal Genin, while Sasuke's total Chakra had already surpassed that of an average Genin. Therefore, he was anxious because without Chakra, he couldn't do anything.

Past midnight, Yu stopped refining his Chakra, checked his progress, and found he had increased it by about one percent.

Lying on the bed, he began to think about the second problem: how to improve his physical strength. His current body had the characteristic of being immune to physical damage, but its durability was too low. If he were to fight someone, he might end up as a meatball after the first round.

"First, don't think about methods from the Hokage world. Those methods are too far-fetched for me right now."

He needed to step outside the scope of the Hokage world and combine his own abilities with other knowledge.

Of course, the so-called knowledge wasn't academic knowledge but rather the knowledge from the various anime and movies he had watched. Since he could now travel to the Hokage world, things from anime and movies weren't impossible to make real.

Soon, he thought of a movie character—Wolverine.

Wolverine was very similar to him, possessing powerful regenerative abilities and an immortal body. Of course, his immortal body couldn't compare to Wolverine's; it was merely a low-tier version of immortality.

Wolverine wasn't considered very strong in the early stages of the movies, perhaps only equivalent to a super-human. A Chunin with excellent taijutsu could possibly be on par with Wolverine.

However, after being modified with Adamantium, Wolverine could be called a terrestrial immortal.

"Adamantium bone structure gave Wolverine an indestructible body. So, could I also get a set of metal bones?" Yu thought.

The more he thought about it, the more he felt this method could work. Using a set of metal bones to support his body would naturally increase his physical durability, and it could also enhance his strength, speed, and so on. It was truly a matter of killing multiple birds with one stone.
