I haven't seen fireworks.

The original technique of turning mud into stone can only look like the wrapped soil, and it will still look like the same when compressed, but the volume is reduced.

Kamiya Keiyun wanted to change it so that the middle was compressed to the surroundings, and finally a cylindrical piece of soil was transformed into a circular stone pipe.

In this way, it not only solves the problem of stacking stone bricks, but also has the load-bearing capacity of the pipe itself, and can also isolate the invasion of groundwater, insects and the like.

He originally thought it would be difficult, but after only trying two or three times, he discovered that it was successful!

It is almost no difficulty to change the appearance of the compressed soil, as long as you think about it in your mind, you will succeed immediately!

"The technique of turning mud into stone has a total of 12 seals, which is much higher than that of the three-body technique, but in terms of difficulty, it seems that there is not much difference?" Shen Gu Jingyun thought he had created a rather difficult technique, but From my own experience, it doesn't seem to be difficult.

Unfortunately, this technique consumes a bit of chakra. Even if you have a high affinity with soil, you still need so much.

He estimated that he could only use this technique four times with his chakra, and each time he could penetrate 5 meters deep. In other words, he could dig a 20-meter-deep tunnel in just a few minutes!

And his chakra needs 8 hours to recover, and if added up, it can be used 8 times a day, or 12 times.

Then, Shengu Jingyun passed the advanced changes of this technique to Heibei, and then watched him perform the paw seal.

"Have you learned it?" Kamiya Jingyun asked.

"I can feel it, but I can't find the feeling you mentioned, the feeling of being one with the soil!" Heibei replied: "And the consumption of chakra is very powerful. I can only use the chakra once. It can dig up to one meter deep! And using too much chakra makes me dizzy and feels like my body has been hollowed out..."

"Is there such a thing?" Shen Gu Jingyun was a little curious. He had never used up all the chakra in his body, mainly because he didn't have any means to consume chakra. He couldn't just use the transformation technique all the time!

As for not being able to blend in with the soil, maybe it’s because it doesn’t have the attribute of soil...

"The fusion of physical energy and mental energy of Chakra atoms. Chakra consumption means that physical energy and mental energy are consumed. Maybe this will happen..." Kamiya Keiyun thought for a while and said: " Then you control the output of chakra and don't dig so deep. Digging 60 centimeters at a time is enough. When your brother and sister come, a family of six can dig 3.6 meters at a time! Then restore chakra, and it will take one night. It should not be a problem to advance 30 meters..."

"How can Chakra recover so quickly? The Chakra I consumed last night took half a sleep to recover!" Hei Bei said.

...

"So when you don't use ninjutsu, you can dig 2.5 meters a night, but you can only dig 0.6 meters a night with ninjutsu?" Kamiya Jingyun asked.

Heibei was silent for a moment. Although he didn't want to admit it, it seemed like this was indeed the case...

"I, did I fail to help you?" Hei Bei asked in a low voice.

"No, this is not your problem!" Kageyun Kamiya shook his head: "After all, you are just a mouse, and your chakra volume is definitely not as large as mine. You don't have earth attribute chakra, and the consumption of controlling earth must be great. ..."

Therefore, it is better to let Heibei dig the hole by himself. He can recover chakra quickly, he can use it twice a night, he can dig 40 meters, and he can dig 100 meters deep in three days!

Konoha Village is not big, with a diameter of only 900 meters (counted from the top of the B station up the river and down the mountain). The location where Kamiya Keiyun lives is only 300 meters away from the wall. To be safe, dig 400 meters away, and it only takes 10 days.

Including the time to dig up, it will take a total of 14 days to dig out!

Subtract these 14 days, and there are still 10 days until October 5th!

enough!

"That's it!" Kamiya Jingyun said: "Without further delay, let's start tonight!"

~~~~~

At night, after Kamiya Yi and Kamiya Hiroaki went to sleep, Heigai was first sent out to bring a wooden stake infused with Kamiya Keiun's chakra into the pit, and then Kamiya Keiyun used the substitute technique!

Shengu Jingyun instantly crossed the floor and appeared in the deep pit!

"It's a bit dark..." Kamiya Keiyun looked around. The whole environment was quite cramped. He could only accommodate himself. It was okay to turn around, but it was a bit uncomfortable to sit down.

But just in time, since he couldn't see his surroundings, he didn't feel claustrophobic. Kamiya Keiyun directly formed a seal, then pressed his hands on the ground and injected chakra into the soil.

"Earth Dungeon: The Art of Turning Mud into Stone!"

boom!

Under the action of Chakra, the soil under Shengu Jingyun's feet instantly turned into a smooth pipe with a length of 5 meters and an inner diameter of 40 centimeters. The ground under Shengu Jingyun's feet was empty and fell directly.

But it's not a big problem, it's just five meters.

Kamiya Jingyun continued to form seals.

boom!

"Huh? It seems to be farther this time, and the inner wall is wider?" Shen Gu Jingyun's perception is very keen, but he doesn't know the exact length, but fortunately, there is Hei Bei, who sent down a roll of ruler.

After measuring it, he found that the pipe made this time was actually 5.05 meters long, and the inner wall width reached 42 centimeters.

Chakra can extend farther and compress the soil more strongly, which is a manifestation of ninjutsu becoming stronger.

If he keeps practicing like this, it won't be impossible for him to be able to open a spell 10 meters long in a few days!

"I have the talent of God's reward for hard work. When I use ninjutsu, my proficiency is constantly improving. Maybe it won't take 14 days at all!" Kamiya Keiyun was a little excited. Then he thought about it again. Chakra is the product of the fusion of physical energy and mental energy. , human beings have activities every day, and it doesn’t matter if they consume a little, but if they are consumed in large quantities, it may harm the body...

Since ninjutsu can evolve, don't use chakra to death. The original plan was to use it eight times a day. Now, six times a day is enough!

He turned mud into stone again, and that was the end of tonight's work.

Including what Heibei dug before, the total depth is 17.7 meters!

"Should I still dig tonight?" Seeing Shengu Jingyun coming up, Hei Bei was a little nervous.

"Do you want to dig?" Kamiya Keiyun asked.

"I definitely don't want to!" Hei Bei said, after all, no one likes to work, and besides, the feeling of exhausting Chakra is too uncomfortable!

"Then don't dig!" Shengu Jingyun thought for a while, and said: "By the way, call Liuli into my room. It's only 9 o'clock. Why sleep? Come to class for two hours before going to bed!"

"Oh..." Heibei stood up and went upstairs with a whoosh.

Shen Gu Jingyun also got up and came to the training room.

Soon, Liuli and Heibei came in, followed by Shengu Sanye.

"I, I can't sleep either..." Mitsuha Kamiya said.

In fact, seeing everyone, a cat and a mouse, busy with their own affairs, how could Mitsuha Kamitu sleep well!

"Alright, then you sit down first and review the three-body technique you learned before, and I will teach them how to read!" Shen Gu Jingyun took out a roll of white paper and began to read softly.

The cat and the mouse sat at the small table and listened carefully. Their attitudes were much more correct than those of the students in the Ninja School.

They also know that Shengu Jingyun's teaching is very effective, but his time is very precious. He has to attend classes during the day, exercise his legs after school, and practice ninjutsu. There is only a little bit between classes every day.

Kamiya Jingyun taught them very traditional courses, first learning the Three Character Classic, and then learning Tang poetry and Song poetry.

Is there a thousand-character text missing in the middle?

That's because Shengu Jingyun didn't memorize it.

In the middle, there are also some courses such as political thought.

He didn't have life and death talismans, three corpse brain pills and other means of controlling people, even if there were, he didn't trust the effect of those things.

If you want to keep secrets, strengthen your will, and make your subordinates withstand torture, the same thinking is more useful than means.

At the same time, in order to protect the two ninjas, when the strength of the two is insufficient, Kamiya Jingyun will not send them too difficult tasks, such as asking Hei Bei to monitor Shimura Ken.

Even if he is a mouse, Kamiya Keiyun is not willing to take this risk.

After thinking about it, Shengu Jingyun didn't plan to let Heibei's siblings join in, because he might not be able to support him.

Everyone in the family knows the existence of Liuli, and Shen Guyi can make an extra meal for the cat.

Heibei eats less, and Shengu Jingyun can even out by bringing more every day.

But how to balance the six mice?

Secondly, if there are too many mice, it will be difficult to control. Now there are only two, and the cat and the mouse can supervise each other.

If six mice come running, can Liuli see it?

As for the third, he doesn't need so many workers now, he can dig holes by himself.

After teaching an article "Ode to the Goose" here and letting the two ninja beasts practice calligraphy on their own, Kamiya Keiyun came to Mitsuha's side again.

"Sister, do you have a way to make money?"

That's right, now that the problem of going out of the village has been solved, another problem lies in front of Shengu Jingyun.

He has no money!

If you don’t have money, how can you buy materials out of the village?
