I haven't seen fireworks.

On the first floor, in the stairwell, there are some debris piled up here, and few people come here. It is quite appropriate to place the tunnel entrance here.

Of course, he would not directly lift the floor openly, but asked Hei Bei to dig a small hole leading to the ground, and then let Hei Bei start working underneath.

"How is it, how efficient is it?" Shen Gu Jingyun asked from above.

"The strength of my claws is more than ten times stronger than before, and now I can do what I used to do overnight!" Heibei said excitedly, "But where is the pile of soil dug out?"

"This..." Kamiya Jingyun thought for a while, yes, this seems to be a problem!

Digging a hole a hundred meters deep will lead back to the outside of the village. Even if you don't have to dig too thick, the amount of earth will still be quite huge.

Kamiya Jingyun grabbed a handful of soil, thought about it, and said, "Pile it in the backyard first. I'm just testing your digging speed tonight! As for the earthwork, I'll find a way..."

"Okay! Don't forget the package you said!"

"Of course not!" Shen Gu Jingyun smiled, and then smiled, wanting to cry.

Yes, mice have to eat too!

Not to mention that today, Heibei's two older brothers and three younger sisters are also coming.

A mouse can't eat as much as a cat, but now there are six...

Especially after becoming Ninja Beasts, their food intake has increased!

"But fortunately, roof rats are omnivores. Maybe I should find a grain merchant to cooperate..." Kamiya Jingyun thought for a while, and he realized that he still didn't know who in the village made grain!

In fact, because he stayed at home before, he didn't know much about Konoha Village and the various political structures...

When he woke up in the early morning, Kamiya Jingyun was shocked to see a black mouse lying peacefully in Liuli's arms, and the two little things were sleeping soundly...

"Ah this..." Kamiya Jingyun was shocked, is this okay? Isn’t it said that cats and mice are natural rivals?

But thinking about it again, even in the previous life, pet cats generally would not do anything to the pet mouse raised by the owner, let alone Liuli is a cat that can talk and communicate with people now.

Kamiya Keiyun put on his clothes and then knocked Heibei on the head.

"What are you doing? I'm so sleepy!" Heibei said impatiently.

"Okay..." Kamiya Jingyun nodded. After all, he had been working all night, so he wouldn't be disturbed.

He glanced at the backyard, and there was indeed a lot of soil piled up in the backyard, more than one meter long, a big pile.

When he went downstairs, Kamiya Yi had already prepared the meal. When he saw Kamiya Jingyun coming down, he asked with vigilance: "Jingyun, didn't you bring a cat back before? Can it catch mice? I was I heard a mouse digging a hole in the house!"

"Ah, mom, don't worry about this..." Kamiya Jingyun waved his hand: "I will take care of it. By the way, don't worry about the soil in the backyard, I will take care of it..."

"Oh..." Kamiya nodded. She usually didn't go to the backyard very much because the backyard was shady, so even if she was drying clothes, she would always hang out in the front yard.

"Indeed, there is still the problem of noise, and we have to find a way to solve it!"

After eating, Shengu Jingyun took a roll of pond, lay down on the stairwell, and measured it downwards.

He marked a circle for Heibei, a circle with a diameter of 40 centimeters, and asked him to dig down.

When we looked down, we found that it was 2.5 meters deep!

"The formula for the volume of a cylinder is V = πr2h, so it dug 3 cubic meters of soil in one night!" Kamiya Keiyun was a little surprised, but after thinking about it again, 3 cubic meters didn't seem like much!

After all, it only took 2.5 meters to dig in one night, and it took 40 days to dig meters.

After 40 days, the daylilies are cold!

Even if Hebei's whole family is called in, the construction period is only shortened to six days, and there is still a distance to dig from the ground to the outside of Muye Village!

"It would be great if I awakened the MC system. It's only 100 meters, and I can finish it in less than a minute!" Kamiya Keiyun sighed, thinking of digging the ground in MC, the soil can be turned into small pieces, and then it can be returned to the ground. It can be put into a backpack, so there is no need to pack it away...

"Wait?" Kamiya Jingyun was stunned, MC system, small pieces?

Shengu Jingyun began to diverge his thinking. He didn't have a backpack, but turning the soil into small pieces might not be impossible!

After all, he had discovered before that Chakra has two characteristics: gravitational force and repulsive force.

If these two characteristics are applied to the soil to shorten the distance between soil molecules, the volume of the soil will naturally be greatly reduced, and the problem of where to pile the soil will naturally be solved!

Kamiya Keiyun also guessed that digging should be effortless. After all, that is Heibei's natal magical power. Can a mouse's son know how to dig a hole?

But transporting the soil to the backyard is very time-consuming, especially for a mouse who cannot use a car, he can only move a little bit, maybe he spends most of his time transporting the soil.

If there is a way to compress the soil, the construction speed can be greatly accelerated!

Kamiya Keiyun first went to the backyard and grabbed a lot of dirt, and then went to school.

Along the way, he began to experiment with chakra a little bit.

Gather the chakra in the palm, and then go to wrap the mud in the palm.

When the amount of chakra is low, it shows the characteristic of absorbing the soil, and when the amount of chakra is large, it shows the characteristic of repelling the soil.

But now that the chakra has surrounded the soil, there is nowhere to release this repelling force, and it can only be concentrated on the soil in the palm.

Then, the individual molecules that make up the soil are compressed by the ubiquitous chakra, and naturally begin to condense toward the center...

Little by little, little by little effort, after studying all the way and then trying two classes in the classroom, the ball of soil in Kamiya Jingyun's hand that was originally as big as a fist turned into a black ball that was only the size of an egg. A stone-like substance...

"It's really possible! But the size is only reduced by about one-third, which is not enough!" Kamiya Jingyun threw the stone-like thing in his hand. The density difference between stone and soil is not big. If it is only reduced by this point, then he still has to find a place to stack it.

At best, it is to turn the piled soil into piled stones, but the opponent's stones are too easy to be found, you might as well pile up the soil!

"However, speaking of it, this kind of fineness in manipulating Chakra is not as good as Jieyin!" Jingyun Shengu thought for a while, and began to try to use Jieyin to mobilize Chakra.

He is already extremely proficient in the twelve seals, and he also knows that the twelve seals correspond to various changes in chakra. Combined with the flow of chakra just now, it is not difficult to deduce the seal style from the results.

Sure enough, Kamiya Jingyun found that the fineness of his chakra control had suddenly increased a lot when he formed a seal.

If it is said that when Kamiya Jingyun first extracted chakra, his control over chakra was 1, then when he practiced "Ming Ming De Fa" and began to shape the human form, his control over chakra was 10, and the spirit plus structure Yin, the control over chakra is 30!

Just after completing the seal, a stronger chakra surged out from the palm of his hand and went straight into the compressed stone. Then it was compressed into a stone as big as an egg. It was compressed again and turned into a pigeon. Egg size!

"!!" Kamiya Jingyun looked at the dark brown stone as big as a pigeon egg in his hand in astonishment. Then he thought about the lump of soil when he went out. The size had shrunk by three-quarters!

"That's it!" Kamiya Keiyun was a little excited. What does the success of this technique mean? It means that the original 1 cubic meter of soil can be condensed into 0.25 cubic meters of stone!

And this Jushen Gu Jingyun feels that it is not over yet, he has only tried once or twice, if he goes further, he might not be able to condense to 0.1 cubic meters, or even 0.05 cubic meters!

Now it is just turning mud into stone, but in the future it will mean turning the earth into steel and turning stone into gold!

"However, why do I feel that I have a close relationship with the soil!" Shen Gu Jingyun felt the soil in his hands. He felt it when he just tried to compress the soil. , he didn't even use much effort!

But I never had this feeling when playing in the water before.

"Is it because I chose to strengthen the muscles of my legs? Or is it because I come from a flower grower, and farming is a talent?" Jingyun Kamiya thought for a while, and then thought of the electric current on Hatake Sakumo's body when he attacked, and Shimura Kenwai No. Wind Ghost, so that's the case, this is the attribute!Is it an affinity for a certain element?

So Hatake Sakumo's main attribute is electricity, Shimura Ken's main attribute is wind, then my main attribute is soil?
