"Kazuya, you dedicate the ninjutsu you developed to the village, of course the village will not treat you badly, according to the regulations, I can approve the award of two ninjutsu of the same level to you as a reward, and it is also to encourage you to continue to work hard in the future, and strive to develop more ninjutsu to increase the heritage of the village! You can think about what ninjutsu you want first. ”

After Echizen Kazuya also wrote the "Earth Escape-Flowing Earth Cocoon Technique" on the scroll, Sarutobi deliberately hung Echizen Kazuya's appetite, and Shi Shiran said that it was a surprise for Echizen Kazuya.

For most ordinary ninjas, the only way to obtain ninjutsu is to contribute to the ninja village, which is awarded ninjutsu according to merit;

And for wandering ninjas, it is even more difficult, often stealing and imitating everywhere, and finally they can make some ninjutsu that are different and full of loopholes.

It's almost impossible for an ordinary ninja to get ninjutsu from their enemies, after all, very few people carry a ninjutsu scroll with them, and it's even more unlikely that they can learn ninjutsu by observing the seals of their opponents in battle, unless you have a writing wheel.

Simple ninjutsu because there are not many knots, even if you don't have a writing wheel eye, you can barely see the opponent's seal order, but if you want to release a ninjutsu perfectly, it's not enough to know the seal order.

Subtle changes in the rhythm and rhythm of the ninja's seal will also affect the chakra's movement, thus affecting the effect of the entire ninjutsu, and this rhythm and rhythm will also change slightly when the speed of the seal changes.

But these subtle things are impossible for ordinary people to observe in battle, especially some high-level ninjutsu, which require a lot of seals, and the users are often ninjas, and it is very difficult to see their seals, let alone observe details such as rhythm and rhyme, so it has almost become an impossible task to learn advanced ninjutsu.

For ninjas from the family, it is much easier to acquire ninjutsu. As a long-term family, there will be more or less some ninjutsu that can be passed on to the younger generations, laying a solid foundation for the younger generations and helping them grow quickly.

And the civilian ninja has a lot of hard life, when he first became a ninja, he only had the three-body technique taught by the ninja school, some simple body skills and blade skills, and the mortality rate was extremely high when performing tasks, and he worked hard to help the village earn commissions as cannon fodder, which was a typical exploited class, and unless the talent was discovered by the village and focused on training, there was almost no chance of getting ahead.

And when the civilian ninja finally saves enough merit for ninjutsu, he is often not too old, and it will be the end of his life to become a middle ninja, and he can only look forward to the child fighting for strength, inheriting his mantle, and counting on the day when he will develop into a new family in a few generations.

Of course, all this has nothing to do with Echizen for the time being, he is one of the lucky few people, not only has the Yamanaka family as the backing, but also has his back against the big tree of the Hokage, and there is no shortage in ninjutsu.

"Grandpa, I want an illusion and a thunder ninjutsu, is that okay?" Kazuya Echizen thought about it for a while and made a decision.

The strength of the illusion ability depends on the strength of one's own mental power and the control ability of the chakra, and these two aspects are what Echizen Kazuya is good at. As long as the Thunder Ninjutsu is well developed, it can greatly improve the strength and speed of the body, and it can also act on the sword, which can well make up for the shortcomings of Echizen Kazuya's current lack of strength. Both of these types of ninjutsu can greatly enhance his combat abilities.

"Illusion and Thunder Ninjutsu? Are you sure? Sarutobi didn't expect Echizen and Kazuku to make a decision so quickly, and he thought that Echizen and Kazuku would also have to go back and think about it before deciding, so when he heard the answer, he couldn't help but be stunned, frowned and asked.

"Well, I've decided, I'll choose the ninjutsu of these two categories!" Kazuya Echizen nodded with a smile and said firmly.

"Okay, then judging from the current effect of the Flowing Earth Cocoon Technique, this should be the same C-level ninjutsu as the Earth Flow Wall Technique, then I will teach you a Thunder Escape Earth Walk and an Illusion Technique Nai Branding Technique, these two ninjutsu are very practical basic ninjutsu, and you should be very simple to learn," Sarutobi Slashed Echizen and was also very sure, so he muttered for a while, and introduced two practical ninjutsu to Echizen Kazuya.

"Well, anyway, I don't know which ninjutsu is suitable, grandpa, the one you recommend must be better than my own choice!" Echizen Kazuya doesn't really care about what he learns, anyway, he can continue to develop new ninjutsu based on them in the future, so that they can achieve the functions they want.

Just like the technique of flowing earth cocooning, when Echizen Kazuya wanted to develop a ninjutsu to control the enemy, he developed it on the basis of the earth flow wall.

And before developing the art of flowing soil cocooning, Echizen Kazuya discovered a very powerful function of the attribute panel, that is, as long as you completely learn a ninjutsu, when you learn other ninjutsu of the same level and type, the learning speed will be incredibly fast.

Just like Echizen Kazuya, shortly after spending nearly two years learning the Tsuchiru Wall, he developed a second Tsuchido Ninjutsu based on the Tsuchigo, "Tsuchi-Cage Technique", which is a simple ninjutsu that creates four rock walls around oneself or the enemy to protect oneself or temporarily trap the enemy.

Compared to the "Earth Flow Wall Technique", there is no change in principle, except that the position of the rock wall has been changed.

To Echizen Kazuya's surprise, with the foundation of the "Earth Flow Wall Technique", it only took him ten days to perfectly master the "Earth Escape - Cage Technique" when the daily practice time was almost the same as the previous "Earth Flow Wall Technique".

After that, the surprise and inexplicable Echizen Kazuya opened his mind and developed a lot of useful and useless strange C-rank earth escape ninjutsu, which is actually a simple change in the shape of the lower rock wall and the position where it appears, like turning into the shape of a pillar and appearing at the enemy's feet, etc.

Because the principle of these ninjutsu is exactly the same, they are all simply using chakra to create rocks, so Echizen Kazuya later simply unified these similar earth escape ninjutsu and renamed it "C-level earth escape".

And as the number of developments increases, the time for Echizen Kazuya to master a new C-class dokufu is decreasing. Probably because he has mastered all the secrets of the C-level Tu Dun, as long as he has a new brain hole now, he can completely master the C-level Tu Dun in less than half a day and use it as he wants.

It wasn't until later that he really lost the desire to continue developing, and Echizen Kazuya stopped this kind of script-like development behavior that began to become boring, and began to explore the earth escape ninjutsu with more changes at higher levels.

However, B-level ninjutsu consumes too much chakra, and Echizen Kazuya is still difficult to afford, so the progress of Tu Dun's cultivation has become much slower, and until now, the proficiency of the "B-level Tu Dun" displayed on the attribute panel is only 31.3%, so he will have the semi-finished ninjutsu of "Flowing Earth Cocoon Technique".

The current "Flowing Earth Cocoon Technique" is actually a ninjutsu between C-level and B-level, compared to the Soil Flow Wall Technique, it also has some more changes in the nature of the soil attribute, that is, the stickiness of sticking to the other party, so its potential is still very large, but Echizen Kazuya is now subject to the amount of chakra and can't play it.

As long as there is enough chakra to use it, then its range, the speed of controlling people, and the hardness of the rock after forming a cocoon will be greatly enhanced, and at that time, it will definitely be able to completely wrap the enemy's whole body, and it will not be like when it was used on Inoue Chuan, just barely controlling his lower body, and it can also allow him to calmly seal and perform ninjutsu.
