Ninjas learn ninjutsu not by looking at a scroll or watching someone else perform it.

In the memory of his previous life, although Uchiha Itachi had seen Fugaku's Fire Escape Fireball Technique, he successfully performed it once. This is not to say that ninjutsu is easy to learn, just look at Sasuke's experience to see how difficult it is.

And Sasuke is already a rare talent in the ninja world. That's the existence of Shikamaru and others who are destined to become the same period as the upper ninja.

So to learn ninjutsu, it usually takes a ninja a dozen times, dozens of times, to try to find that feeling. But the ninja's chakra is enough to be used a few times. Like Yichen, it is only enough to perform C-level ninjutsu once a day, and if you practice it once a day, Yichen has a high talent, assuming that it takes thirty attempts to succeed.

That Yichen was going to drastically reduce the amount of chakra it took to learn other things within a month, just to perform ninjutsu once a day.

And a month later, Yichen only learned ninjutsu, and he had to perform it skillfully to improve the success rate of ninjutsu. It is also necessary to be able to adapt to a variety of different environments, and try to simplify the Indian forms used to perform ninjutsu.

If you calculate the same thing, one year may not be enough. And the ninja is on a mission most of the time, and to keep the chakra, you can't be in a bad state every time you perform a mission, which is looking for death.

Based on this situation, the ninja world has developed a drug that can quickly replenish the chakra that is consumed and has no negative effect on the body. It's not so much a medicine as a medicinal diet.

This medicinal diet is rich in a lot of nutrients and can quickly replenish the body's consumption. A person who has eaten the medicinal diet can practice chakra several times a day. If you eat medicinal diet for three meals a day, the amount of chakra that can be refined more a day can reach about 50C.

It's enough for ninjas to perform C-rank ninjutsu dozens of times a day. And with this kind of continuous practice, it is easier to find the feeling and understand it more deeply.

Usually, the amount of a medicinal diet is 30 meals, and if it is counted as three meals a day, it can last for 10 days. In these ten days, ninjas can practice C-rank ninjutsu hundreds of times. The chances of learning are very high.

Usually, the village will reward a medicinal meal after a ninja is promoted to a middle ninja, and try to help a new middle ninja learn a C-level ninjutsu. Such a middle ninja can be qualified for the position of captain, otherwise what is the use of just relying on the name of the middle ninja? It's nothing more than a stronger lower forbearance.

Of course, the village only provided medicinal food, and the ninja had to pay for the ninjutsu themselves.

However, Yichen's parents left him two C-level ninjutsu scrolls, which saved him a lot of expenses.

With the task reward voucher given by Onoki, Yichen registered at the contribution office and exchanged it for one and a half, that is, 45 meals of medicinal food at the exchange office.

Then it took another 90 points to consign to a dedicated chef to handle it. This price is actually not expensive, at the beginning, Yichen could get two contribution points for copying a book, and it was normal to spend two points on making a medicinal diet.

After all, the medicinal diet made by professional people is also more effective than ordinary people.

There was no delay, there were still a few days left to leave school, and Yichen would naturally not be wasted. At noon on the same day, he began to eat medicinal diet, and the effect of medicinal diet was obvious, and after eating, the whole body had inexhaustible strength. This is a sign of over-replenishment of the body, and if the excess energy is not consumed in time, it will not be long before the body will have symptoms such as nosebleeds. In severe cases, it can also be harmful to the body.

Yichen had long known the pros and cons, so he didn't hesitate. Begin to mobilize the chakra in the manner described in the scrolls of the Earth Flow Wall.

The reason why Yichen first learned the earth flow wall is simple, the earth flow wall has few changes, and after the chakra is separated from the body, it is mainly to form an earth wall in front of him. Unlike the Tulong gun, it is also necessary to control the direction of the gun, the number of guns.

I saw that Yichen's hands quickly made seals, a total of seventeen seals, because he was not proficient in this way of mobilization, so it took more than 9 seconds. Then Yichen squatted down and slapped the ground with both hands at the same time, and all the chakras that were mobilized poured into the ground.

And then there was no then. Not to mention the earthen wall, there is not a single earthen ridge or earthen bag. At this point, 1.3C of chakra is wasted.

Although he had long expected the difficulty of learning C-level ninjutsu, seeing that it had no effect at all, Yichen couldn't help but twitch the corners of his mouth.

The movement of chakra in the body is aided by imprints, and its flow outside the body depends on experience. For the first time such a large number of chakra transfers, Yichen was completely unrestrained. As a result, the chakra is completely messed around.

Fortunately, the effect of the medicinal diet began to work, and Yichen began to extract chakra, and did not stop until the body reached the upper limit of storing chakra. After extracting the chakra for the first time, I felt that my body was not hollowed out, which was really comfortable.

In this way, Yichen began to practice again and again, and slowly began to control the chakra to form an earthen wall.

At the beginning of the formation of a small soil bag, then a large soil bag, aware of the deviation of the dust, began to change the control method, this time began to form a small ridge, and then felt that the right direction of the dust, began to control more finely. Slowly, the rudiments of an earth flow wall appeared.

Then, after repeated attempts to become proficient, Yichen finally mastered the earth flow wall when he consumed 27 meals of medicinal food. A full 9 days have passed.

In the past nine days, Yichen has to spend more than an hour training on the earth flow wall after meals every day.

Now I have been able to complete 14 seals in more than 5 seconds, and then 100% successfully cast the Earth Flow Wall.

The number of stamps has been reduced from 17 to 14, and the number of chakras has been reduced from 1.3C to 1.1C.

Yichen was very emotional, thanks for the crossing, thanks for the strong spiritual power. Far beyond the chakra control of ordinary people, it has brought too much convenience to Yichen's ninjutsu cultivation. Usually, a new mid-ninja has to spend a whole serving of medicinal food, which is 30 meals, before he can barely perform C-level ninjutsu.

And Yichen Feifei has completed the cast, and has also improved his proficiency, not to mention the 100% success rate, and the number of link seals has been reduced by three. In addition, the stamping speed has also been significantly improved.

Now Yichen's C-level ninjutsu earth flow wall's sealing speed is about the same as the speed of D-rank ninjutsu doppelgänger and transformation technique. This is also the standard that Yichen himself uses to judge whether he has fully mastered the ninjutsu of Tuliubi.

Now as the best ninjutsu: stand-in technique, Yichen can be printed 3 times in 1 second. And the doppelganger technique, transformation technique, and earth flow wall are only about 2.6 marks in 1 second.

At this point, Tuliubi's practice came to an end, and Yichen decided to rest for a while to let his body relax before learning the next ninjutsu.

Another side benefit of this period of learning is that Yichen's understanding of soil properties has been greatly deepened. He had now transformed the chakra into an earth attribute, and it was all in a single thought. No more jerky, no hindrance.

Next, Yichen decided to become proficient in the water attribute chakra first. Originally, his plan was to learn the Tulong gun after learning Tuliubi. But after discovering that learning ninjutsu can improve his proficiency in attribute changes, Yichen changed his mind. I plan to learn a water escape ninjutsu first, and practice water attribute changes through water escape.

Originally, Yichen had 1,000 points of contribution under his name, but after the reward of the S-level task arrived, it directly reached 11,000 points. It's enough for Yichen to buy an average B-grade ninjutsu, and it's enough for C-level ninjutsu to buy several.

So Yichen decided to exchange for a C-level water escape ninjutsu that suited him.

Flipping through the introduction of the Water Escape Ninjutsu in his hand, Yichen found that there were not many high-level Water Escape Ninjutsu in Rock Ninja Village, but there were still a lot of C-level mainland goods. For example, the water archery technique used by the fog ninja who sent Yichen to the first kill at that time was included in the rock ninja village.

Speaking of that fog ninja, Yichen remembered one thing, at that time, that fog ninja seemed to be performing a kind of perceptual ninjutsu before he died.

For the original Yichen, the contribution value is not rich, so naturally he can't exchange too much ninjutsu. Now that I can't spend so many contributions in a short period of time, is it possible to redeem a perceptual ninjutsu practitioner.

In the enchantment class before, although Yichen was also on duty in the perception detachment, working there, there was no need for Yichen to perform ninjutsu, the ninja only needed to use the enchantment that had been arranged in advance to spread the senses. This is very simple for Yichen, who has excellent mental power.

Yichen, who has had a perceptual experience, is very envious of the feeling of God's perspective. So Yichen asked the staff if there was a sentient ninjutsu to redeem.

The staff took Yichen a much thinner booklet, which contained some introductions to C-level perceptual ninjutsu. After seeing the price of C-level perceptual ninjutsu, Yichen was taken aback.

The price of C-level ninjutsu for ordinary combat is above 1000 points, just like the 17-seal Tuliu Wall, the price is 1700 points, and the price of 15 seals of the Tulong gun is 1900.

For the same ninjutsu, the smaller the number of seals, the higher the price, for example, the price of 10 seals is 4500 points.

The highest-priced C-level Earth Escape Ninjutsu is a 6-seal Earth Sneak, and the price is higher than some B-level Ninjutsu, reaching 13,000 points. 19 seals of the earth only need 3500 points.

But in any case, if you don't consider the ninjutsu that has simplified the number of seals, the general C-level combat ninjutsu is between 1000 and 4000.

However, perceptual ninjutsu is significantly one level higher than combat ninjutsu. The cheapest C-level perceptual ninjutsu on the list is also at 3200 points, which is still a chicken rib ninjutsu with a large number of seals, a large amount of chakra, a small perception range, and strong perception fluctuations.

The perception ninjutsu that is really practical and cost-effective is at least 7000 points.

Yichen took a fancy to the perception ninjutsu used by a Konoha ninja in a memory of his previous life, and after sealing it, he could slowly perceive the chakra situation around him by pointing a finger on the ground. The perception range increases with the amount of chakra, chakra control, and mental power. It can be said that if you buy it once, you can use it for a lifetime.

There are many benefits, that is, the price is slightly higher, 13000 points. Can't afford it!

Yichen wrote down the price and decided to start saving money after exchanging it.

Next, Yichen began to look for a suitable water escape ninjutsu. First of all, exclude those that need to consume a large amount of chakra, which is their own shortcoming, and then focus on chakra control, such ninjutsu is more cost-effective for themselves.

There are not many ninjutsu left to meet these two requirements, and Yichen is surprised to find that the water archery technique is actually among them. However, in the end, Yichen did not choose water archery, and water archery will form a large number of water arrows, which is a ninjutsu that covers a small area of strikes. What Yichen wants is a single attack ninjutsu.

In the end, Yichen chose the water escape - the art of the water line. This ninjutsu is not high in attack in C-level water escape, and it is a ninjutsu that concentrates the water attribute chakra at one point and then makes a concentrated breakthrough. The attack of Shui Dun is already weak in the Five Elements Ninjutsu, and the power of the Waterline Technique is even weaker in the Shui Dun Attack Ninjutsu.

The biggest reason why Yichen chose this ninjutsu is because of its compressive properties, which have great potential. In the memories of his previous life, the Fukasaku Immortals of Myoki Mountain and the second-generation Hokage Senju had used this highly compressed water escape, but they used it for cutting.

The waterline technique also uses the principle of compression, but the density is not enough at this stage to be used for cutting, and it can only be used to point to where to hit, which plays a role similar to a thousand books.

However, considering that it only needs to consume 0.9C of chakra, Yichen thinks it is appropriate, at least it is good to practice the change of water attribute chakra. And because of the low practicality, the price is also cheap, only a reserve price of 1000 points.

Yichen exchanged the waterline technique, reluctantly glanced at the manual of perceiving ninjutsu, and left the exchange office.
