The six people of the second and fifth classes slaughtered their respective captains at the instigation of Yichen. After a lively meal, they dispersed.

Today's assessment has made Yichen very tired, so I will take a day off today, and tomorrow I will go to receive medicinal food and practice ninjutsu.

Yichen, who has just been promoted to the middle ninja, will have a short vacation according to the practice of the village, and this holiday is used by the newly promoted middle ninja to learn C-level ninjutsu, and to improve his combat power in a short period of time, and this system has not been suspended even in wartime. And Tian Na also needs time to practice the teleportation technique, so the fifth class has no tasks recently.

Yichen, who received the medicinal diet and came to the training ground again, was a little excited, this training was the welfare of the village, and as usual, the village would arrange for the corresponding senior Zhongnin to come over to guide Yichen.

It's just that when Yichen filled out the application, he wrote that he was practicing the art of waterline. There weren't many water-type ninjas in the Rock Ninja Village, and coupled with the strange ninjutsu of the Waterline Technique, Yichen doubted that the village could find a suitable candidate.

But this is not something I can control, and my purpose is not to learn the art of the waterline, I already know this ninjutsu. His purpose is to have someone guide him to level up the waterline technique.

Yichen's understanding of water attributes is actually not strong, and his advantage is that his control is amazing. When walking the path of water attribute cultivation, there is a feeling that experience leads to understanding.

At first, I was able to perceive the water attribute because of the water stand-in, which was confused at that time, and later I barely mastered the change of water attribute through repeated practice.

With this level of understanding, it is impossible to realize the development of ninjutsu.

After Yichen finished eating the medicinal food, the waiting Zhongnin hadn't come yet, and he didn't care, and began to practice the technique of the water line by himself.

A while ago, thanks to the improvement of Chakra's control ability, Yichen was barely able to achieve pressurization treatment in the waterline technique. But this kind of pressure is far from enough, not to mention cutting the ten tails like the second generation Hokage in the expectation, just for actual combat, it may be better than the kunai shuriken.

The chakra cost of the waterline technique is not large, but if you apply pressure, then the chakra cost will be much higher. Now the dust is not easy to control, sometimes the chakra is ineffective if it is used too much, and sometimes it is effective when it is used less, but it has little effect.

In this way, one person practiced for most of the day before a ninja came to Yichen.

I didn't expect it to be a shinobi.,It seems that there is really no suitable shinobi in the village.。 Although he guessed that the other party was here to guide him, Yichen still held his maneuver and tried to remain calm.

Sure enough, after the man walked in front of Yichen, he took the lead in speaking: "You are Yichen, you are so young, you can be promoted to Zhongren at such a young age." I'm the shinobi who is in charge of guiding you in the practice of the waterline technique this time, my name is Seichi. ”

Yichen hurriedly bowed and saluted: "Hello, I'm Yichen." It's such an honor that the village should have a shinobi like you to guide me in ninjutsu. Yichen's words are not sycophants, this kind of reporting task is not highly paid, and it is only invited by the village to contribute money, so everyone doesn't like to take this kind of task very much.

Seichi was a more easy-going ninja, and smiled awkwardly when he heard this, and said, "Actually, the village can't find a suitable middle ninja, and there are few people in the village who practice the waterline technique you chose." Actually, I don't know how to use the waterline, so the village sent me mainly to guide you in the cultivation of water attribute changes. ”

Hearing this, Yichen Feidan was not disappointed, but overjoyed: "Great, my mastery of the change in the nature of my water attribute is actually very average, and the only thing that I can use to perform ninjutsu is the chakra control talent." Just now, I was still worrying about how to strengthen my water attribute cultivation. ”

Then Yichen said his understanding of the nature of water, the purpose of the waterline technique, and the idea of adding the principle of water pressure to the waterline technique to develop a new ninjutsu.

Se listened to it at first with the mentality of pointing out the juniors, but the more he listened, the more surprised he became, and he thought, "Shouldn't you, a new middle ninja, be entangled in how to perform ninjutsu?" How to think about the high-end field of form change, ninjutsu development, and water attribute perception is coming. ”

Especially when he heard the idea of Yichen pressure, Seichi had a feeling of being sudden. It seems that my perception of water attributes has deepened in an instant.

"Who's instructing whom?" Seichi thought.

After Yichen finished speaking, Seichi fell into deep thought. Yichen could only wait from the sidelines.

After a long time, Seichi came back to his senses, and when he saw Yichen's expectant gaze, Seichi smiled and said, "Originally, I came to guide you, but I didn't expect to be guided by you first." In this case, in return, I will give you a detailed explanation of the water attribute in the next few days, and you can also listen to my feelings. ”

Yichen was a little dazed at first, how could I guide you, but the last two sentences directly made him excited. This kind of guidance will not have a second situation in the ninja world except for the inheritance of master and apprentice. Today is really my lucky day.

Next, Se explained to Yichen the relevant knowledge of water properties at the beginning, which was not in these books, and could only be exchanged with contributions to the village. Now Seichi is teaching himself for free.

During the twenty days that Yichen took the medicinal diet, Seichi did not do tasks, but trained with Yichen in the training ground. The two of them, one spoke wholeheartedly, the other listened carefully, and Yichen's brain circuit, which was different from the ninja world, would put forward some strange insights and conjectures from time to time.

Gradually, the more the two chatted, the more speculative they became, and then Seichi instructed Yichen to practice ninjutsu, and let Yichen understand the truth through practical operations.

What excites Yichen the most is that once when Seichi talked about the characteristics of water attributes that also have a certain cutting ability, he also taught Yichen a B-level water escape ninjutsu, and the water escape breaks the cold current. Let Yichen deepen the characteristics of the water attribute cutting ability through the water escape ninjutsu of breaking the cold current.

With super chakra control, with the careful guidance of a senior who is good at water escape, and with the blessing of medicinal food, Yichen actually successfully performed this B-level ninjutsu.

Of course, Yichen also understands that he can use it now because of the help of the huge amount of chakra brought by the medicinal diet. In a normal battle, it is impossible to perform it yourself.

From the perception of water attributes explained by Seichi, Yichen understood that he had a misunderstanding before, he always wanted to amplify a certain feature of water attributes, thus ignoring the biggest characteristic of water attributes is the variety of performance. That is to say, there are many, many characteristics of water attributes, and if you don't have any of them, you will no longer be water.

For example, if Yichen wants to increase pressure in the waterline technique, he must take into account that the conduction of the waterline pressure with a large increase in pressure is in all directions, and the pressure in other directions must be contained in order to achieve a strong blow.

The biggest gain in the past twenty days is actually Seichi, although he doesn't realize much from Yichen, but Yichen's words to break the inertia of thinking can often inspire him.

With the cooperation of Yichen's medicinal diet, the upgrade of a waterline technique has not yet been completed. Seichi completed the development of three ninjutsu.

Seichi himself is a master of water escape ninjutsu in the village, but practicing water escape in Iwa Ninja Village is too limited and restricts his growth. But Yichen helped him open the door that imprisoned him.

So in the past twenty days, Seichi's strength has improved by leaps and bounds, and there is a faint meaning of elite forbearance.

These Yichen can't feel it, and he still doesn't know the difference between the upper ninja and the elite upper ninja. He just saw from Seichi's generosity to him that his gains were definitely not small.

However, Yichen was very content, and when he was originally assessed by the middle ninja, he realized that the attack method was too single and the ninjutsu release was too slow, so he thought about practicing the waterline technique to increase his attack power and casting speed. He didn't plan to use this opportunity to learn a new ninjutsu, but with Seichi's generosity, he managed to learn a B-grade attack ninjutsu to break the cold current. There is nothing not satisfied?

And in the past 20 days, my harvest is far more than that. In the past 20 days, the biggest change in Yichen is that in the course of water attribute change, he has completed the transformation from a primary school student to a high school graduate. Seichi's explanation made up for the gap in his theoretical knowledge, and the rest of Ruth had to go by herself, and the teacher's teaching was actually not very useful.

And the benefits of this shift are numerous. Greatly reduced the casting speed and chakra consumption of water-based ninjutsu. The number of connection prints has achieved a qualitative breakthrough.

Although no new ninjutsu has been fully developed in the past twenty days, the power of the upgraded waterline technique has long been incomparable. After trying, Yichen was able to use the new waterline technique to directly penetrate the Earthflow Wall he cast, and cause damage to the people behind the Earthflow Wall.

Original Waterline Technique: 12 prints, 2.7 prints/second, 0.8C. Now Yichen only needs 5 prints to perform the original waterline technique, and the printing speed is 3.5 prints per second, which consumes 0.6C chakra.

The upgraded version of the Waterline Technique, the stamping method has a subtle speed regulation, which requires 7 stamps, and the stamping speed is 3.5 stamps per second, consuming 5.8C of chakra.

Twenty days of countless ninjutsu practices have made a qualitative leap in Yichen's sealing speed. Yichen felt that now his ninjutsu could really be used in actual combat.

As long as you can practice two more Earth Escape Ninjutsu in the days to come, and simplify the seal, I believe that your strength will increase a lot.

At the end of the practice, Se Yiyi has always said goodbye to Yichen, he has gained so much, he needs time to transform this harvest into actual combat ability, and he has to explain his value to the upper echelons through the task.

I'm going to start the mission again tomorrow, so I'm going to check out the enchantment class today.

I haven't been to the enchantment class for more than 20 days, and I don't know how the fragments of the "Fire Domain" of the enchantment class have been deciphered.

Thinking of this, Yichen was a little impatient. Hurriedly quickened his pace.

The enchantment class is not as leisurely as Yichen these days, and the entire enchantment class's research on the fragments of the "Fire Domain" has not stopped for a moment. The three upper ninjas take turns on duty to lead the team, working in three shifts 24 hours a day, non-stop experiments.

Although it has not yet been cracked, the theoretical gains in it are far greater than everyone expected. The method they discussed a long time ago to find inspiration from the ninja school children didn't have much effect. However, in the process of this analysis and research, various ideas emerged one after another.

In addition, the enchantment class that obtained the Vortex Clan's sealing technique was already in a period of rapid growth in the level of sealing techniques. This time, under the impetus of this research project, several rounds of qualitative breakthroughs have been completed.

Now the number of people who have reached the level of A-level sealing skills in the enchantment class can't be counted on two hands, and the number of B-level people is not even known to Onogi and Mizuwon.

Yichen's return was warmly greeted by everyone, and many familiar and unfamiliar sealers couldn't wait to share the research process with Yichen during this time.

After listening, Yichen was dumbfounded, when discussing research methods at that time, everyone put forward a lot of ideas, and these days they are trying one by one.

I thought that after such a long time, there should not be many experimental projects left. As a result, there are more projects that have not been tested now than before, I don't know how many. It turns out that in the process of research, people are constantly coming up with new ideas.

Sometimes there are dozens of new ideas after a single experiment.

Some of these ideas are refinements in detail, and some are whimsical ideas.

After listening to everyone's descriptions, Yichen was immersed in the bombardment of various novel ideas and the analysis report of various test results.

It wasn't until someone reminded Yichen that it was time to go home that Yichen came back to his senses. After looking at it, he saw less than one-tenth of the documents, and Yichen felt that he didn't have enough time.
