The Marvelous Shadow Clone Technique

Digging for sand is for making glass.

Making glass is naturally for manufacturing purification instruments, such as funnels, beakers, graduated cylinders, and flasks.

And making purification instruments is for making perfume!

That's right, when it comes to luxury goods, Kamiya Keiyun's first thoughts are bags, lipstick, and perfume.

However, bags require this skin and that skin, which he doesn't understand, and lipstick is even more complicated; he knows absolutely nothing about it.

Perfume, on the other hand, is simple.

He studied botany himself, not only learning about flower cultivation but also personally making perfume with flowers.

"Can I help with anything?" Sanyō asked, seeing her brother return with a bucket of sand.

"Remove all the leaves and stems from those flowers, leaving only the flowers, then find a rack and place them in the yard to air dry naturally!" Kamiya Keiyun said, glancing at the sky. "Or better yet, put them in the room where we train. It might rain this season!"

"Okay!" Sanyō went to get busy.

Kamiya Keiyun, meanwhile, began sifting the sand, washing it first with water to remove impurities.

The remaining sand became pure white river sand, with a slight yellowish tint.

According to the standard method for making glass, this sand should be heated and fired into glass, but Kamiya Keiyun didn't have a kiln.

His chosen method was still ninjutsu.

Mud can be molded into stone, so shaping sand into glass should be no problem, right?

He raised his hand and formed a seal: "Earth Release: Sand to Glass Technique!"

The composition of soil is quite rich, including organic matter, minerals, humus, microorganisms, and a large amount of water.

The main material of glass is also found within the components of soil. You can't say that sand mixed in soil is soil, but when picked out separately, it's no longer soil.

And Kamiya Keiyun's chakra doesn't seem picky about these things. Whether it's sand or soil, it works the same way. It even affects the metallic minerals within the soil.

If classified according to the Five Elements, it should include both Metal and Earth attributes. As a result, Kamiya Keiyun felt that calling this technique Earth Release might not be entirely appropriate.

It would be more fitting to use the Earth, Wind, Water, and Fire classification. So, should this be called Earth Style?

Under Earth Style, one could further divide it into Sand Style, Metal Style, Earth Release, Rock Style, and so on.

"Huh, this seems like it has potential. If I get an iron sword and control it with chakra, wouldn't I be able to achieve Sword Flight?" Kamiya Keiyun's thoughts began to wander.

Following this line of thought, Kamiya Keiyun would first need to be able to manipulate objects with chakra.

Could he do it?

Kamiya Keiyun tried, but it didn't work.

Object manipulation doesn't require an instantaneous burst of chakra, but rather a sustained external effect.

However, once chakra is released outside the body, it dissipates rapidly and cannot exist for long.

"Forget it, forget it. Focus on what's in front of me first. I'll make a note of this idea!" Kamiya Keiyun jotted the idea down in his little notebook.

As of now, this little notebook already contained 11 problems, all discovered by Kamiya Keiyun while researching chakra and learning ninjutsu, and which he found difficult to solve himself.

Before, he might have thought about researching them himself, but with Snake Uncle around, he could ask for help in a month.

Snake Uncle is one of the Sannin, basically one of the most advanced individuals in the world when it comes to chakra. He should be able to easily answer his questions!

So, let's continue making glass.

He wasn't sure if it was because he had chosen the wrong materials, but in front of him, the glass was indeed made, though it wasn't colorless and transparent. Instead, it was a pale yellow with a greenish tint, like a beer bottle.

Additionally, perhaps his mental focus wasn't fine enough, as the beaker he shaped had a pitted surface.

It wasn't that obvious, but a beaker, unlike a pipe, requires a very high degree of surface smoothness. The level Kamiya Keiyun had achieved so far was still a considerable distance from what he desired.

Kamiya Keiyun wasn't discouraged. It was his first time making glass, so it was bound to be unsatisfactory. He would just keep trying.

Fortunately, the beaker was much smaller than a pipe, and he didn't feel any chakra consumption.

For a beaker this size, he felt he could spend the entire afternoon!

It was a shame about the color, but it couldn't be helped. His current requirements weren't high, so he'd make do.

At noon, after eating, Kamiya Keiyun attempted to cultivate Cooking Gold, Serving Jade for the first time.

He infused chakra into his stomach, small intestine, and large intestine.

These three organs have a vast surface area and involve numerous meridians. This time, the effect wasn't as pronounced as when he strengthened his legs.

Kamiya Keiyun's small amount of chakra could only strengthen them a little, distributing a barely perceptible amount of chakra within each meridian.

"I feel a bit drowsy, but I don't feel any significant improvement in food digestion. Is the enhancement too low?" Kamiya Keiyun pondered. If his original digestive capacity was 100, and now it's 101, he wouldn't be able to tell the difference.

"The amount of chakra is too small, causing the enhancement of the digestive system to be too weak. The weak enhancement of the digestive system leads to reduced digestive efficiency of food. And low digestive efficiency of food means that the accumulation of chakra cannot increase."

However, interpreted from another perspective, the chakra used to amplify the digestive system would, in turn, grant Kamiya Keiyun a stronger body and more chakra.

This was a positive feedback loop. Although the speed might be slow, it was stable.

Just as he was about to continue polishing the bottle, Keiyun suddenly remembered the two ninjutsu techniques Snake Uncle had taught him.

There was nothing much to say about Summoning Technique; he didn't want to find the White Snake yet. However, the Shadow Clone Technique was something else!

"This jutsu was given to me by Snake Uncle after I expressed my desire not to go to school, so this jutsu can help me solve the problem of not wanting to attend class?" Kamiya Keiyun recalled the special feeling he had while experimenting with ninjutsu at Snake Uncle's place.

"Shadow Clone Technique!" Kamiya Keiyun summoned a shadow clone and then commanded, "Take this paper, go outside the door, write any character you want, place it under the main door, and then dismiss yourself!"

"Okay!" His shadow clone had a similar personality to his own—honest, rigid, full of curiosity, and not one for tricks.

He took the paper and went straight out the door. A few minutes later, Kamiya Keiyun's head went blank. He hurriedly got up, went to the door, and picked up the paper!

There was no writing on the paper, only a large question mark!

"What the hell?" He was stunned. When he recalled the clone, he had unexpectedly received the clone's memories!

What was the principle behind this?

Aren't memories formed by synapses between nerve cells? Why could a shadow clone, made entirely of chakra, generate memories? Why did the shadow clone have its own thoughts? Why did the chakra return to his own body after the shadow clone dissipated, instead of scattering into the air?

After being stunned for a while, he understood Snake Uncle's intention. This shadow clone had a physical form and wasn't afraid of being seen through, so it could attend class in his place!

In that case, he would naturally be freed from those boring lessons.

However, the acquisition of a new ninjutsu was accompanied by more and more questions.

Kamiya Keiyun felt like he was that circle; as it grew larger, the unknown it came into contact with also increased dramatically.

He was a little... excited!

Kamiya Keiyun raised his hand. He felt that the Shadow Clone Technique held great potential, and if he studied it deeply, he might gain unexpected rewards!
