Analyzing the Ninja World Starting from Konoha

A new week begins at the Ninja Academy.

The morning sunlight streamed into the classroom, filling the air with a lazy, languid atmosphere.

Just like going to school or going to work, many people are listless and lack energy.

Aoba sat in her seat, resting her chin on one hand. Between the fingers of her other hand, a grayish-white pebble rolled from her index finger to her little finger, and sometimes flipped from the back of her hand to her palm, so nimbly as if it had a life of its own.

Kurenai turned her head and stared intently at Aoba's hand before finally asking a question.

"What are you doing?"

"Practice finger dexterity."

Aoba, with a straight face, spouted nonsense: "The speed of forming hand seals depends on the coordination of the fingers, which can train nerve reflexes."

Aoba's fingers twitched slightly, his fingertips feeling the texture and feel of the rock, trying to resonate the frequency of his chakra fluctuations with the material of the stone.

This is the first step in practicing Earth Release: Nature Transformation – understanding the weight and structure of "Earth".

"Really?" Hong blinked her big, ruby-like eyes, looking eager to try. "I'll give it a shot too."

She picked up a pebble of similar size from the ground and tried to spin it between her fingers, just like Qingye did.

pat.

The pebble fell onto the table before it had even spun halfway.

Red, unconvinced, picked it up again and tried, but this time it flew off and almost hit Obito, who was sleeping in front of her.

"This is so difficult..."

Her cheeks puffed out, looking somewhat deflated.

"Pebble is unstable and not suitable for beginners."

Aoba stopped what she was doing, took a coin out of her pocket and handed it to Kurenai, "Try this."

As he spoke, he demonstrated it once.

The coin rolled and undulated on the back of my finger like waves, its movements elegant and fluid.

"It's actually quite simple as long as you master the coordination of your center of gravity and fingers."

Aoba patiently explained several points for applying force.

Hong took the coin and tried it a few times according to Qingye's method.

Although it was a bit awkward at first, I quickly got the hang of it and successfully spun the coin around my fingertip.

"I learned!"

Hong exclaimed in surprise, a bright smile spreading across her face.

"Yes, once you're proficient, you can gradually increase the speed."

"Um."

Red Dot nodded, as if it had found a new toy, and spun around happily.

Soon the coin was spinning rapidly on her finger.

Having received a new toy, Aoba was bound to show it off to her best friend. She was lying on the table when she soon heard Shizune and Rin's voices.

Soon, cheerful laughter rang out, indicating that they were all learning quite quickly.

Spinning a coin with your fingers isn't actually that difficult; anyone with decent finger dexterity can master it quickly. Furthermore, hand seals are a fundamental skill for ninjas, and many people practice hand seals to some extent before entering the Ninja Academy, so their finger dexterity shouldn't be too bad.

"Pshaw, what's so difficult about that? I'll definitely learn it in no time!"

As Rin's loyal admirer, Obito always kept a close eye on her every move. When he saw Rin playing with a coin, he came over to join in.

As a result, Obito chased the falling coin all over the classroom, causing laughter from everyone around him.

This simple yet skill-based game quickly spread like a virus throughout the class.

During breaks, almost everyone had a coin in their hand, and the classroom was filled with the clinking sound of coins falling onto the desks.

Seeing so many people playing with coins, Obito couldn't resist trying it out during class. However, he was too bad at it, and the coins kept falling to the ground with a thud. In the end, Araki-sensei, who couldn't stand it anymore, kicked him out to stand outside as punishment.

"idiot!"

Kakashi, as always, was sharp-tongued, but after looking at the coin that had rolled to his feet, he thought for a moment and picked it up.

After trying to spin it twice, the coin began to roll smoothly between Kakashi's fingers, and the speed increased.

Lin, who was standing nearby, also noticed Kakashi's little actions. She was very surprised to see Kakashi get his hands on the object after just a couple of turns, and thought to herself.

"Geniuses really do learn everything fast!"

"It's definitely a good method. It can train the muscles in your fingers, making hand seals smoother," Kakashi thought to himself. Then he wondered if it would be more concealed if he replaced the coin with a shuriken or a kunai.

……

"This is boring."

Kurenai sat there listlessly. While all her classmates were playing, she, the "trendsetter," found it all rather dull.

The coin flips between the fingers, the thumb flicks it away, and then it lands precisely back in the palm of the hand.

The moves are pretty cool, but once a lot of people do them, they become just so-so.

This thing is indeed not difficult; once you get the hang of it, the novelty wears off quickly.

Hong turned her gaze to the instigator who was lying on the table beside her, pretending to be asleep.

"Aoba~ Is there anything else?"

Whether it was her nature or not, Hong somehow learned to act coquettishly without being taught.

Qingye immediately felt goosebumps all over her body.

Hong seemed to realize that her tone was a bit off, her face turned red, and then she glared at Qingye fiercely.

Seeing Hongnai's fierce yet endearing appearance, Qingye immediately burst into laughter.

"Here you are."

Aoba took a pen from the pen holder, twirled it lightly between his fingers, and the pen shaft drew a perfect arc on his finger.

Red's eyes lit up instantly; this looked way cooler than spinning a coin.

The pen flew between his fingers, sometimes swirling at the base of his thumb, sometimes rolling on the back of his fingers, the movements so fluid it was as if the pen had grown wings.

"I'll give it a try!"

As she spoke, Hong took out her pen, intending to start spinning it.

Aoba quickly stopped him; if it were just a matter of spinning a pen, he wouldn't need to demonstrate it.

"The principles are the same, only the center of gravity is different."

"But that's not what I wanted to say. Think about it, besides pens, could you try something else?"

"Like kunai?"

As he spoke, Aoba slightly turned his wrist, and the pen that was originally in his palm turned into a kunai. Then, with another flick of his wrist, the pen reappeared in his palm.

Then, upon closer inspection, it turned out to be a shuriken!

"this……"

Hong was stunned.

Having achieved her goal, Aoba began to explain to Kurenai.

"This is a visual deception created by exploiting blind spots and hand speed..."

"The principles are all the same. By utilizing blind spots and subtle hand movements, one can also conceal a sword in their hand, using techniques such as hiding a sword in the sleeve."

"Besides this, Hong, you can try to extend it yourself. You're so smart, you're sure you can come up with a lot of ways to play."

"That's for sure, humph."

After being praised by Aoba, Hong raised her head slightly, put her hands on her hips, and looked like she was very awesome.

Okay, keep it up.

Aoba clenched her fist with one hand and encouraged him, then told Kurenai to go find her friends to demonstrate.

Aoba watched Hong skip and hop around, a slight smile playing on her lips.

Unfortunately, there aren't many decent games in the ninja world. The most popular ones are ninja games, similar to ghost hunting in my previous life, which require multiple players and a certain amount of space to play.

This edutainment approach injects some vitality into the barren world of ninja games, and it is also hoped that Kurenai's future ninja journey will be smoother.

Anyone who isn't too stupid can see that whether it's spinning a coin or using a pen, it can be a great aid in the practice of hand seals and throwing techniques.

In the world of ninjas, strength ultimately matters. He can't stay by Kurenai's side forever, and it's highly likely that he won't be in the same group as Kurenai after graduation.

The biggest problem now is to survive the Third Shinobi World War safely. Although they all grew up safely in the original story and became special Jonin of Konoha, it is hard to guarantee that there will be no unexpected changes due to his time travel.
