Ruri's Educational Issues

He'd just acquired the Three Divine Techniques, and Keiyun wasn't paying much attention in the subsequent classes. Not only was he distracted during lessons, but the moment the dismissal bell rang, he vanished without a trace.

Umino Iruka watched this clearly from up front and couldn't help but shake his head. His evaluation of Kamiya Keiyun began to drop.

What good was talent if one didn't work hard? They wouldn't achieve great things in the future!

Although not much was being taught now, it was the perfect time to observe a person's nature. He had seen plenty of talented children like Kamiya Keiyun who lacked patience and disliked studying.

It was a shame, but Umino Iruka had no intention of intervening. After all, the teachers at the Ninja Academy didn't have the kind of sense of responsibility that required every student to succeed.

Kamiya Family residence. Keiyun had just called out, "I'm home."

Then he heard Kamiya Sanyō's roar, "Nature is prone to change, nature is prone to change! How can you not remember these three words!"

"Nature is prone to what?"

"Change, change!"

"Nature is what change?!"

BANG!

Keiyun looked up and saw his sister Sanyō storming downstairs. Upon seeing Kamiya Keiyun, she acted as if she'd found a savior. "Little brother, you're finally back! That cat is so stupid, I can't teach him at all!"

"How is that possible?" Kamiya Keiyun was stunned. He had felt the cat was quite intelligent when he communicated with it yesterday!

"You don't believe me? You try!" Sanyō said irritably. "I tried to teach it the Three Character Classic today, and it didn't even finish the first sentence!"

"Is that so?" Kamiya Keiyun looked up and saw the kitten already on the stairs. It stretched lazily, then leaped.

Keiyun quickly reached out and caught it.

"Ruri? Are you really unable to learn?" Kamiya Keiyun asked.

"Learn what?"

"'Humans at birth are naturally good, their natures are close, their habits are far apart'?" Kamiya Keiyun recited.

"'Humans at birth are naturally good, their natures are close, their habits are far apart!'" Ruri repeated.

"'If not taught, nature is prone to change; the way of teaching is to value focus!'" Kamiya Keiyun recited again.

"'If not taught, nature is prone to change; the way of teaching is to value focus!'" Ruri continued to repeat.

Kamiya Keiyun turned to Sanyō and saw her glaring at him with a wronged expression. "Ruri, do you have a problem with me? Why is it that you can't recite it when I teach you, but it's fine when he teaches you?"

"I think Ruri is like a child. You need to be patient when teaching her. At her age, learning new things will definitely be slow!" Kamiya Keiyun said cautiously.

"Am I impatient?" Sanyō said irritably. "I've been reciting these two sentences for almost a whole day!"

"Why don't you try again?" Kamiya Keiyun handed Ruri back to Sanyō.

"Okay!" Sanyō, feeling a bit wronged, still took Ruri.

"Teach her well. Later, I'll teach you three Ninjutsu, real Ninjutsu!" Kamiya Keiyun tried to use motivation.

"Hmph!" Sanyō hugged Ruri and stomped upstairs, saying as she walked, "Ruri, be serious! Use the learning speed you had just now!"

"Whew." Kamiya Keiyun shrugged. Was it difficult?

It didn't seem difficult!

He went to the backyard and began to study the Three Body Technique.

It wasn't about further practice, but about trying to understand the principles behind these three techniques.

Focusing only on application and neglecting theory had long been proven by modern science to be a wrong path.

Even if one rose rapidly through application, they would have to arduously catch up later and repay the debt from before.

Kamiya Keiyun's learning had always been about knowing not only what but also why. Although, so far, this was still just a goal.

First was the Clone Technique.

He formed the hand seals, then felt the flow of Chakra within his body. But unfortunately, the speed of this change was too fast.

He felt the Chakra in his body flow rapidly the moment the seals were completed, and then it returned to its original position.

The entire process happened extremely quickly, perhaps only 1-2 seconds. Kamiya Keiyun didn't even have time to perceive it before an illusionary image of himself appeared beside him.

If he hadn't felt a slight depletion of Chakra, he would have thought it was an illusion!

"Okay, slowly, step by step!" Kamiya Keiyun slowed down the speed of his hand seals.

The Clone Technique required three seals. He first completed the first seal, and then he felt the Chakra in his abdomen begin to transfer to his legs.

The second seal: Chakra spread from his feet to the surrounding area, forming a sensing range of about 5 meters.

Then, Kamiya Keiyun could guide it, causing it to condense in one direction.

The third seal: shaping!

The entire process had to be completed within 2 seconds. Exceeding 2 seconds carried the risk of Chakra losing control. If the Chakra was still within the body, it would retract to the abdomen; if it was outside, it would dissipate into nature.

"So that's how it is. Chakra is released from the feet onto the ground and then forms an illusory human figure." Kamiya Keiyun nodded, but his doubts not only didn't decrease, they actually increased.

First, why could the hand seals control Chakra to perform these actions, but his own mind couldn't?

Second, when he practiced the Clone Technique under Kakashi's guidance, the clone automatically appeared beside him, even though he hadn't set a position for it to appear.

By the second and third attempts, he discovered he could indeed control the position where the clones appeared, even more than one. As long as his Chakra reserves allowed, he could create up to three clones simultaneously within a five-meter radius.

So, if the clone's position required mental control, what explained the success of the first attempt at the Clone Technique?

Third, it wasn't strange that Chakra could form a human shape. He could already mold it into a human shape inside his body, and the external space was much larger. The amount of Chakra needed for manipulation was less, making the difficulty countless times lower than his Bright Virtue Method.

But how did the clones get their colors?

How did Chakra gain color? Shouldn't it be light blue? Why did it appear in various colors on the human body—red, orange, yellow, green, cyan, blue, and purple?

As everyone knows, color appears because a substance reflects sunlight. So, can Chakra also reflect sunlight?

Can consciousness even control the color of Chakra reflection, reflecting whatever light one desires?

If it were controlled by consciousness, then a person has so many colors on their body. Such a massive computational load would require a supercomputer to control even in modern times. Yet, ninjas calculate this with their consciousness and only feel a slight headache.

Was this reasonable?

Kamiya Keiyun pondered and experimented for a long time. Besides gaining a deeper understanding and mastering the Clone Technique, he made no further significant progress.

"What internal energy, true Qi, can't compare to Chakra at all. This energy seems to have a very high energy level and level of mystery!" Kamiya Keiyun silently noted these questions.

He didn't have the ability to unravel these mysteries yet and could only research them slowly in the future.

"Tsk, if only I had an electron microscope."

After two exclamations, Kamiya Keiyun continued his research. Next were the Transformation Technique and the Substitution Technique!
