I haven't seen fireworks.

Sand is dug to make glass.

Making glass is naturally for making purification instruments, such as funnels, beakers, measuring cylinders, flasks...

And making purification equipment is for making perfume!

That's right, when talking about luxury goods, the first thing that comes to mind for Kamiya Keiyun is bags, lipstick, perfume...

But he didn’t understand the leather that a bag needs. Lipstick was even more complicated, and he knew nothing about it.

But the fragrance is very simple.

He himself is a plant student, not only has learned flower planting, but also made perfume with flowers himself.

"Is there anything I can do for you?" Seeing her younger brother come back with a bucket of sand, Sanye asked.

"You remove all the leaves and stalks of those flowers, leaving only the flowers, then find a shelf, put them in the yard, and let it dry naturally!" Shen Gu Jingyun said, and looked at the sky again: "Still put it in our In the training room, it might rain this season!"

"Okay!" Sanye went to work.

Shengu Jingyun sifted the sand, and first ran it through with water to remove impurities.

The remaining sand becomes pure white river sand with some yellow.

According to the formal method of making glass, the sand should be heated and fired into glass, but Kamiya Keiun did not have a kiln.

The method he chose was ninjutsu.

Mud can be molded into stone, and sand can be molded into glass, so there should be no problem!

Raise your hand and make a seal: "Tu Dun: The Art of Turning Sand into Glass!"

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

The main material of glass is also among the ingredients that make up soil. You cannot say that sand is soil when mixed in soil, but it is not soil when it is picked out alone.

As for the chakra of Kamiya Jingyun, it seems that he is not picky about these things. Whether it is sand or soil, it still takes effect, even including metal minerals in the soil.

According to the Five Elements classification, it should include the two attributes of metal and earth, so Kamiya Jingyun felt that it might not be appropriate to call this technique Earth Release.

It is more appropriate to use the classification of land, feng, shui and fire, so this should be called earth escape?

Under Earth Escape, there are Sand Escape, Gold Escape, Earth Escape, Rock Escape, etc...

"Hey, this seems to be a bit tricky. If I get an iron sword and control it with chakra, wouldn't it be possible to fly with the sword?" Shen Gu Jingyun's thinking was a little divergent.

If you think along this line of thinking, first of all, Kamiya Kageun must be able to use chakra to control objects.

Can it be done?

Kamiya Jingyun tried it, but it didn't work.

Because what Yumon wants is not a momentary burst of chakra, but a lasting effect outside the body.

But once Chakra is released outside the body, it will dissipate quickly and cannot exist for a long time at all.

"Forget it, forget it, concentrate on the matter in front of you first, and write down this idea first!" Shen Gu Jingyun wrote down this idea in a small notebook.

So far, this little notebook has recorded 11 problems, all of which were problems that Kageun Kamiya discovered when he was studying chakra and learning ninjutsu, and that he found difficult to solve.

In the past, he might think of doing research on his own, but with Uncle Snake, he can find Uncle Snake to solve it in a month.

Uncle Snake is a Sannin. He is basically the person who has reached the top of the chakra path in this world. He must be able to answer his own questions easily!

So, keep making glass.

I don't know if it's because he didn't find the right material, but in front of him, the glass was indeed made, but it wasn't colorless and transparent, but like a beer bottle, it was light yellow with green in it.

In addition, maybe because he was not careful enough, the surface of the beaker he made was full of bumps and bumps...

In fact, it's not that obvious, but beakers are not pipes, and the requirements for surface smoothness are very high. As far as Kamiya Keiyun's current level of production is concerned, there is still a certain distance from what he wants.

Shen Gu Jingyun is not discouraged either. The first glass making is definitely not satisfactory, so just keep trying.

Fortunately, the beaker was much smaller than the pipe, so he couldn't feel the chakra consumption at all.

With just such a big beaker, he felt like he could make it all afternoon!

It's a pity that the color of this beaker can't be helped, but it doesn't matter. His requirements are not high for the time being, so he will make do with it.

At noon, after dinner, Kamiya Jingyun tried to practice cooking gold and jade for the first time.

Inject chakra into the stomach, small intestine, and large intestine.

These three organs are actually huge in size and involve quite a lot of meridians. This time it is not as obvious as when strengthening the legs.

Kamiya Jingyun's chakra can only be strengthened a little bit, that is, a little bit of chakra distributed in each meridian.

"I feel a little sleepy, but I don't feel any obvious feeling of food digestion. Is the intensity of the enhancement too low?" Kamiya Keiyun thought, if the original digestion capacity was 100, and now it is 101, then it really can't be felt. difference.

"The amount of chakra is too small, and the effect of strengthening the digestive system is too weak. The effect of strengthening the digestive system is weak, resulting in a decrease in the digestion efficiency of food. And the digestion efficiency of food is low, which means that the amount of chakra accumulated increases. Not going..."

However, from another perspective, chakra is used to increase the digestive system, and the strength of the digestive system will bring Kamiya Jingyun a stronger body and more chakra.

This is also a forward cycle. Although the speed may be slower, it is better than stability.

Just as he was about to continue grinding the bottle, Jing Yun suddenly remembered the two ninjutsu that Uncle Snake taught him.

There is nothing to say about spiritism, he doesn't want to find the white snake yet, but there is something about the shadow clone technique!

"Uncle Snake gave me this technique after I expressed that I didn't want to go to school. So this technique can help me solve the problem of not wanting to go to class?" Kamiya Keiyun recalled the special ninjutsu experience when he was experimenting with ninjutsu at Uncle Snake's house. Feel.

"Shadow clone art!" Shengu Jingyun summoned a shadow clone, and then ordered: "Take this piece of paper, go outside the door and write something casually, put it under the door, and then disband yourself!"

"Okay!" His shadow clone is similar to his own personality, honest and old-fashioned, full of curiosity, and can't do tricks.

He took the paper and went straight out. A few minutes later, Kamiya Jingyun was confused, then he stood up in a hurry, came to the door, and picked up the paper!

There are no words on the paper, only a big question mark!

"Damn it?" He was stunned. When the clone was retracted, he actually received the memory of the clone by the way!

What is the rationale for this?

Isn't memory the synapse formed by nerve cells? Why can a shadow clone made of pure chakra produce memories? Why does the shadow clone have its own thoughts? Why does chakra return to one's own body after the shadow clone dissipates, rather than dissipating in the air?

After being stunned for a while, he understood what Uncle Snake meant. This shadow clone has a physical body and is not afraid of being seen through, so it can take the class instead of him!

In this case, I will naturally be freed from the boring courses.

However, the acquisition of a new ninjutsu is accompanied by more and more doubts...

Kamiya Keiyun felt like he was that circle. As it grew bigger, the unknowns he came into contact with also increased sharply...

A little excited!

Shen Gu Jingyun raised his hand. He felt that the technique of Shadow Clone has a great possibility. If we study it in depth, there may be unexpected gains!
