Although all countries have suffered heavy losses, and it seems that there is no winner, in fact, it is Konoha who wins. World War II was essentially a war waged by the four great powers to grab resources, and Konoha was the country that the four countries used as the main target for grabbing. So although many people died in the battle, Konoha finally held on, and in terms of strategic purposes, Konoha won.

It's just that although Konoha won, after all, he is on the defensive and has no ability to counterattack, so although the four countries were defeated, they did not sign any unequal treaties.

Although the ninjas on the front line have not yet returned, the war is almost over, so the life of the village is slowly recovering and becoming much more lively than before. This is not very suitable for Yichen, after all, the war broke out at the beginning of the crossing, and he has lived in the war years for four consecutive years, and it is normal for him to be unable to keep up with the pace of the peace era all of a sudden.

However, these little things can't distract Yichen now, and Yichen is now focused on learning the sealing technique. With the growth of age, Yichen's physical fitness is improving rapidly, and now Yichen's chakra has reached about 15D. Around 10D, you can perform C-level ninjutsu, so the amount of chakra of Yichen can also be recorded as 1.5C.

However, so far, Yichen has not learned C-level ninjutsu because he has no time. Physical training and physical training take up half of the time, and the rest of the time is spent practicing sealing. Therefore, Yichen didn't have time to practice C-level ninjutsu, and secondly, Chakra was consumed in the process of learning sealing techniques.

After these years of study, Yichen has learned about half of the sealing techniques in the data room of the enchantment class, which is not to say that Yichen's sealing techniques are powerful, but that the sealing techniques in Iwa Ninja Village are too few and too low-level.

Due to Chakra's high talent for control, Yichen was highly treated in the enchantment class, and one of the most important points was the qualification to learn sealing.

Among the dozens of bookshelves in the data room, several are bookshelves that have been sealed by the sealing technique and require permission to view. Among them, the most are various conjectures and speculations about the sealing techniques of the enemy country, followed by the experience of the sealing techniques possessed by the country, and the rest are the details of the sealing techniques and various data records.

Yichen counted, there were a total of seventeen C-level sealing techniques and six B-level sealing techniques. As for none of the A-ranks, it is said that there are only two A-rank sealing techniques in the Iwa Ninja Village, both of which are in the Tsuchikage Building.

Yichen has learned and is able to perform most C-rank sealing techniques. Although the rest didn't learn it, they also understood the principle, and the reason why they wouldn't do it was because of the incompatibility of attributes. As for the B-level sealing technique, Yichen had already carefully studied 2 of them. Due to the lack of chakra, Yichen could not cast it directly, but he innovatively split the sealing technique and divided it into three parts to practice separately. Although it is impossible to combine and cast B-rank sealing techniques, there are indeed ninjas who follow Yichen's method and learn sealing techniques in three steps, and then successfully cast B-rank sealing techniques after combining them.

For this reason, Yichen was specially approved to learn all B-level sealing techniques, after all, with the help of Yichen's method, there were seven or eight more B-level sealing masters in Iwa Ninja Village at once. This may not be a big deal in Konoha but it's a great deal in Iwa Ninja Village, you must know that there are only three A-level sealing ninjas in Iwa Ninja Village in total, and one of them is still Onoki.

So Yichen was recorded as an A-class mission this time, and was allowed to learn all the sealing techniques in the data room. This is remarkable, you must know that Yichen has learned all the C-rank sealing techniques early, but he has never been able to touch the B-level sealing techniques. Later, he was cheeky enough to ask to see Ohnogi, and only with Ohnogi's special approval could he have the opportunity to learn a B-rank sealing technique.

This also spent all the contribution points of more than a year of his time, and he made a lot of storage scrolls for more than a year, and occasionally made guest appearances as perception ninjas, and was on duty in the enchantment center, with a monthly income of about 600 contribution points, excluding expenses, and saved more than 6,000 contribution points before and after.

Fortunately, the rewards are also large, with C-level non-combat missions contributing more than 10 points, B-level 100 points or more, and A-level 1000 points or more. The rewards for combat missions tend to be twice as high as for non-combat missions. Since Yichen has obtained the qualification to learn the remaining 5 B-level sealing techniques, the contribution value is settled according to the lowest level, which is 1000 points.

Anyway, this comes and goes, Yichen is equivalent to exchanging more than 5,000 points of contribution for 6 B-level sealing techniques, plus other side rewards for A-level tasks. For example, money is 1 million taels. The reward for D-level tasks is 5,000 taels to 50,000 taels, C-level is 50,000 taels to 200,000 taels, B-level is 200,000 taels to 1,000,000 taels, and A-level is 1,000,000 taels to 3,000,000 taels. Yichen got the lowest grade of 1 million taels for A-level tasks. This wave is not a loss.

For more than a year, most of Yichen's expenses were spent on cultivation, with hundreds of contributions and tens of thousands of taels of investment every month. (Because the war lasted too long and the village's finances were tight, the silver taels in non-combat missions were greatly reduced) Because he realized the importance of contribution points early, everything Yichen could buy with silver taels was used for silver taels, so although the contribution points could save more than 6,000 points, there was basically not much silver taels left. So now that 1 million taels have arrived at once, Yichen is somewhat uncomfortable.

It is worth mentioning that Yichen's parents' pension was parked a year ago. Not only him, but because of the continuous expansion of the war, the pension of all children who have the opportunity to become ninjas is parked for a year, and the village promises that in the future, these children can learn a C-level ninjutsu for free when they meet the requirements.

And the village will arrange a middle ninja to guide for an hour.

This arrangement is beneficial to Yichen, because he entered the enchantment class early, has a stable income, and because of his excellent performance, his income is actually higher than that of ordinary shinobi. Although the silver reward is less, the contribution value is still there, and there is no shortage of money at this stage, so it is feasible to exchange the pension for the future. But for many children, it is miserable, and the pressure on their lives at this stage is suddenly much greater, which directly slows down the growth of their ninja path.

Yichen had recently learned 5 sealing techniques that he could only learn but couldn't meet the requirements, so he didn't practice directly, but began to summarize the sealing techniques he had learned. Since there was some information about the sealing technique in the memories of his previous life, Yichen wanted to combine the two and innovate.

There is not much positive knowledge of the sealing technique in the memory of the previous life, but the different vision can still bring a lot of aura to Yichen. For example, there is information about the Four Elephant Seals in the data, but there is no Five Element Seal, and Yichen has the impression that the Great Snake Pill and Zilai will also be sealed by the Five Elements. In addition, there is no record of the sealing seal.

All these can point out the research direction for Yichen. Compared to other people who are bound by the village's book collection, Yichen's mind is much more open-minded.

Therefore, during this time, the captain of the upper ninja in charge of the seal of the enchantment class of the branch temple has been discussing the five elements seal with Yichen. The Five Elements Seal is very demanding for ninjas, if one person can learn five chakra nature changes at the same time.

Generally, those who can do this are at the shadow level, so the branch temple began to be a little disappointed. However, Yichen proposed that the five upper ninjas could cast a partial sealing technique of one attribute at the same time, and then merge together to form a complete five-element seal.

Not to mention whether or not we can find five Shangnin who meet the conditions, just how to maintain the stability of the five sealing techniques performed by five different people, so that there is no internal rejection, and Yichen and the temple are stumped.

In the end, under the reminder of the Ming Society, a person who has been making scrolls all his life, five scrolls can be prepared in advance, and the positions that need to be connected can be reinforced by carving runes, so as to reduce rejection.

Therefore, after the pace of the war slowed down, the sealing squad dispatched a large number of people to conduct research on the runes of the Five Elements Seal. In the end, under the leadership of the Ming Society, with a lot of new materials, the production of this kind of scroll was theoretically realized.

Originally, the matter ended here, and this thing may not have a chance to be put into use, so the scroll of the Five Elements Seal was not really made.

But no one expected that the first use of this thing would come so quickly and so suddenly.

It turns out that the ninjas on the front line have begun to return one after another, but something has happened along the way. The accident was triggered by a special ninja named Katsuragi. As a veteran shinobi in Iwa Ninja Village, his special stems from the fact that he has a tailed beast sealed in his body: the Five-Tailed Mu King.

As a human pillar force, Katsuragi is the same as other pillar forces of this era, not a perfect human pillar force, and does not get along with the tailed beast in peace and friendship, but always guards against suppressing the tailed beast.

With Katsuragi's strength, with the help of the power of the seal, it would be fine in peacetime, but during the war, at the request of the village, Katsuragi still used the power of the five tails twice. This caused the seal, which was not particularly advanced, to loosen.

This time, Katsuragi was one of the first ninjas to return to the village, and the reason was to return to the village as soon as possible to solve the problem of sealing. Whoever wanted to look forward was about to go to the village, but the tailed beast still ran away.

Maybe it's the Five Tails who also realized that this was a rare opportunity, so they did their best to attack the seal.

When Yichen received the notice, he was practicing at home, it was the holiday of the ninja school, and there were still a few days left before the school left, and he planned to become proficient in the changes of the water attribute chakra before the start of school.

That's right, in the past year or so, Yichen has made another big progress in learning the water attribute chakra change. It's just that unlike the enlightenment-like epiphany when learning the earth attribute, the cultivation of the water attribute chakra is progressing little by little.

Although Yichen has mastered the changes in water properties, it is very immature. Let's understand it this way, if Yichen Chakra is enough now, he can learn Tu Dun at any time, but he can't learn Shui Dun because his proficiency is not enough.

When the dark part saw Yichen, Yichen was looking at a glass of water in a daze. When Yichen was told to immediately follow the other party out of the village to carry out the mission, he still couldn't react.

When he was carried by the shadows and arrived at the place of the incident, he was directly stunned by the scene in front of him.

Although the five tails are not completely out of trouble, the size of the half-tailed beast is not small. It's raging everywhere, but fortunately, the damage caused is not great, because he is now suppressed by the earth escape of Onogi.

But Yichen's quasi-shinobi can also see that this suppression is temporary, Katsuragi's state is declining, the sealing technique that trapped the five tails is being destroyed, and it is only a matter of time before the five tails break the seal.
