In his previous life, Yichen had never figured out why Naruto, who was just a scumbag when he first appeared, could progress so quickly. If it is because the amount of chakra is far beyond ordinary people. Then the amount of Naruto chakra at the beginning far exceeded that of Kashinobi.

Now Yichen understands that the realm is not enough. Ninjas can only better exert their strength after reaching the standard in terms of willpower and mental power. Otherwise, there will be chakra, and it will always be just a lower ninja.

There has always been a misconception in the previous life, that is, ninjas had a period of rapid growth in strength at the age of fourteen or fifteen. Most of the twelve small powerhouses in the original book grew by leaps and bounds during this period, and then basically reached the level of special forbearance or even forbearance.

In fact, this period of rapid growth of ninjas has little to do with age, mainly due to the increase in reading power, the increase in perception, and the firmer willpower.

Some ninjas who had special experiences in their childhood, such as Kakashi, Ninji, and Iara, had actually experienced a rapid increase in strength before this age.

Now Yichen also feels this change, the kind of change that he can perceive his progress every day.

Yichen is not a real child, and it is very difficult for Yichen to grow up like a child, and general emotional stimulation cannot bring results. Originally, Yichen might have a bloody battle with the enemy one day, and only in the crisis of life and death would he truly comprehend the will of the upper ninja level.

But no one expected that after experiencing the power of an A-level ninjutsu at close range, Yichen really began to change his cognition. Only then did I understand what kind of world I was in and what role I was playing. So under this understanding, Yichen strengthened his belief in becoming stronger, and the most important transformation of his ninja career was completed.

Since then, Yichen has had a total of three ideological changes, the first time was when he met the fog ninja spy when he was in the ninja school, and that time Yichen realized the cruelty of the ninja world and began to understand that this is not a game, not a comic, but the life he is experiencing. The second time was the Zhongren assessment, and then Yichen had a certain understanding of his own strength and began to form the self-confidence of a strong man. The third time was this time, and this time Yichen really realized that he was a ninja for the first time, and he was already a ninja with extraordinary abilities.

The three realizations came in a timely manner, and they just corresponded to the three periods of Yichen's growth, the lower forbearance, the middle forbearance, and the upper forbearance.

Now Yichen's strength is far from reaching the level of Shangnin, but at this rate of progress, it won't be long before he can leave the white cat and Xiaoshi behind and become a real Shangnin.

In the next training, Yichen's progress speed saw that the white cat and Xiaoshi were envious, jealous and hateful. Although Yichen practiced ninjutsu fast before, it was only fast in Yin Escape, but now Yichen is not only illusion - the speed of the body binding technique is simplified and sealed, and even the progress of other ninjutsu, such as the instantaneous body technique, is more than a step faster than before.

In addition, the cultivation of the earth clone is also very smooth, and even the weakest aspect of Yichen: the sword technique, after a few days of evil supplementation, has gradually started. Yichen estimates that if it weren't for the end of the training camp, if he gave himself a few more days, his anti-perception ninjutsu and earth stealth would also be improved.

These are not the biggest gains, Yichen's biggest gain is that after the increase in willpower, the transfer of Chakra has been smoothed a lot. The advantage is that the printing speed has broken through again, from 4-4.5 prints per second to about 4.3-4.8 prints now. In addition, the amount of chakra consumed by performing ninjutsu has also been reduced accordingly.

And what is surprising is that this progress continues, and it will not stop until Yichen's strength reaches a new level.

The rapid progress of strength brings about the restlessness of eagerness to try, and Yichen now understands Ersuke very well, because now Yichen really wants to go to Yicang to try it and see if he is really good again.

However, after careful analysis, Yichen still gave up, and during the mid-year ninja assessment, Icang was able to use B-level ninjutsu in actual combat. After such a long time, I believe that the current strength of Yicang is no longer what it used to be. Maybe people already have the strength to forbear, but it's uncomfortable not to look for it.

At the end of the training camp, the first task of Zidian is still border patrol, and this task has the advantage that it can be properly arranged for practice. Once you arrive at the border, you don't have to spend time on the road. Moreover, the ninja world has just been in a period of peace, and during this period, the major powers will not take the initiative to provoke conflicts, and the task is relatively leisurely.

Therefore, Zidian's arrangement is clear to everyone, just to give everyone a buffer for their sudden improvement in strength, so as not to misestimate the strength of themselves or their teammates when they go to the battlefield. And the three of Yichen also felt that a month of intensive training was not long enough, and their strength could be further improved. Yichen needless to say, the feelings of the white cat and Xiaoshi are even stronger, watching Yichen make rapid progress day by day, and the two of them are also anxious to break through themselves.

However, Purple Lightning's arrangement was doomed to fail, and as in previous missions, after the 18th team arrived at the border, they first exchanged information with the regular ninjas stationed at the border. This is a common thing, but this time there was an accident, after the 18th team came to the border, they saw a number of vigilant ninjas, and they knew without asking, something must have happened.

After Yichen and several people proved their identities, they entered the border post and got in touch with the person in charge here.

It turned out that since five days ago, there have been ninjas who have disappeared one after another, first one or two lower ninjas, and then even middle ninjas who went out alone. As of yesterday, there was even a whole team of Zhongnin squad in charge of the investigation who were all missing.

In charge of this outpost is a special shinobi named Miyake, who was very excited when he saw the arrival of the 18th team, and said to Ziden: "You have come at the right time, this kind of task of searching for traces of the enemy is not our specialty. And being able to silently kill a mid-ninja squad shows that the opponent's strength is not weak, and the squad at our outpost does not have the strength to complete this task. I'll leave it to you in the dark. ”

"There was also a dark group before you, and this dark group is now looking for clues in this area." As he spoke, Miyake pointed to an area on the battle map, "This area is also the patrol area of the Nakashinobi team that disappeared yesterday. ”

After listening to Miyake's description, Ziden asked for a detailed information, and then the four of them set off towards the suspicious area.

The four of them took turns reading the information as they hurried. After reading it, the four of them began to discuss in a whisper.

The white cat said: "First of all, it is possible to solve an entire middle ninja team without alarming other patrol ninjas, and without leaving any traces of battle on the scene, the other party will either shoot with multiple people, or the strength will exceed that of the middle ninja a lot, at least one upper ninja." ”

Seeing that the three of them nodded in agreement, the white cat said again: "Judging from the time of the disappearance of the ninja several times, the other party did not act separately, so the number should not be much." So I'm guessing that the enemy is one or two shinobi or an elite squad. ”

Little Stone added: "That's right. In addition, the other party did not leave a corpse.,It's very strange.,The other party attacked the middle and lower ninja.,Most of them were lower ninja.。 The intelligence value of these ordinary ninjas is not high. It shouldn't be worth it for a team of elites or individual shinobi to risk squatting nearby. So I'm guessing that the other party's purpose might be the ninja's corpse. ”

Yichen said: "Now the ninja at the outpost is just missing, maybe the other party's purpose is not necessarily a corpse, but a living ninja." ”

Yichen knows that there are many examples of experimenting with living people in the original book. I believe that in addition to Orochimaru who was discovered, there should be a lot of people who were not discovered.

The white cat and the little stone both frowned when they heard this, but they didn't say anything, obviously they also knew that what Yichen said was not impossible.

After a while, several people entered the patrol area, and without Zidian explaining, Yichen began to perform perceptual ninjutsu. With this breakthrough, Yichen's perception range has also increased a lot, from more than 1 km to about 1,400 meters.

It's just that this is the limit perception that Yichen can ensure that there is no omission of this premise, that is, the maximum sensing distance after confirming a direction. Yichen controls his perception and circles around him like a radar. After perceiving it for a while, Yichen discovered four chakra fluctuations. After a detailed analysis, Yichen made a judgment.

"The discovery of four ninjas should be the Shadow Squad that set off before us. Do you want to go to the rendezvous? ”

Zidian said, "Merge first." Then he led the three of them to follow the direction that Yichen was pointing.

It didn't take long for the two dark teams to converge, and after a complex series of code communication, both sides confirmed each other's identities. Then began to exchange situations, saying that it was an exchange, but in fact, the main thing was that Yichen listened to the other party's report.

Yichen listened to the other party's description of the situation while performing perceptual ninjutsu again. It's just that this time under the close perception, Yichen really noticed that there was something strange about the chakra of these four people.

I was shocked, could it be that this was the enemy pretending, but this is unlikely, it is impossible to hide the perception ninjutsu such as the transformation technique. Yichen didn't make a sound, and after a careful sense, he suddenly reacted. Whispered: "You are poisoned! ”

The captain of the opposing team was telling the situation, and when he heard Yichen suddenly interject, he was obviously stunned, what is poisoning, he is fine.

Yichen hurriedly added, "Check your chakra and see if you can find any abnormalities." Your chakra is strange to my perception. ”

The four of them didn't dare to be careless after hearing this, knowing that the ninja's methods are changeable, so they began to check themselves, but the three middle ninjas checked for a while and didn't find anything abnormal, only the upper ninja seemed to have noticed something, and his brows were furrowed.

After a long while, the shinobi came back to his senses and said solemnly: "There is indeed a problem, but the problem is very hidden, and I still don't know what this poison does. ”

Zidian asked, "Can it be cleared?" ”

The shinobi said: "I can't do it, I don't have a clue at all." I didn't even feel the poison, but when I controlled the flow of chakra, I felt a little different from usual, not as smooth as usual. ”

Even Shangnin couldn't remove the toxin, and he couldn't even find out that he was poisoned, which showed that the other party's level of use was very high, and now that the enemy was dark and I was clear, everyone suddenly felt tricky.
