On the last day of the holiday, Yichen was training in ninjutsu alone in the dark training ground.

Earth Escape - Rock Breaking Technique, Yichen first cast an earth flow wall, and then formed 19 seals, and the chakra that consumed 35C performed the rock breaking technique sent by Nagato. I saw that the original earth flow wall turned into fine rocks, and shot forward one after another.

Water escape - the technique of blisters, this time Yichen has 20 seals, consumes 40C chakra, a blister is spit out of Yichen's mouth, and it hits forward at a very fast speed, and in the process of advancing, Yichen can control the size of the blister. Finally, the blisters reach the target area, shaking the boulders in the target area, and other small stones are flying around. This ninjutsu is also a C-level ninjutsu sent by Nagato.,Nagato himself has no shortage of chakra.,The ninjutsu sent by him turned out to be a ninjutsu that consumes a lot of money in the same level.。 If this is replaced by Yichen when he first became a middle ninja, he really can't use it.

B-level Earth Escape - Heart Decapitation Technique, Yichen first sneaked under the set target puppet by sneaking in the soil, and then formed 27 seals in the soil, consumed 21B chakra, and performed the ninjutsu that Kakashi used to bully Sasuke in the original book.

B-level earth escape - camouflage technique, Yichen made 31 seals in the same place, consumed 12B chakra, and then Yichen's body disappeared from the place. There was a mirror not far from Yichen, watching himself disappear in the mirror, Yichen smiled with satisfaction. Then I felt it again, well, I still have to consume 5C of chakra per second, which is not much, and I can afford it.

B-level Earth Escape - Sclerosing Technique, Yichen who returned from the stealth state formed 24 seals, consumed 35B chakra, and then one of Yichen's arms hardened into stone with the naked eye.

"Whew~~" Yichen let out a long breath, and in just this moment, he consumed almost one-fifth of the chakra.

B-rank ninjutsu can't afford it.

In the past few days, Yichen has returned to the original days of chakra shortage, and the number of times he practices ninjutsu every day is no longer counted in hours, but is determined by the amount of chakra in his body.

Fortunately, now Yichen's chakra control is strong enough, and the amount has reached the level of upper ninjutsu, so he barely completed the practice of five ninjutsu before the end of the holiday.

The two C-level ninjutsu sent by Nagato are ignored first, and the three ninjutsu that Yichen chose by himself have also been carefully considered, mainly to enrich his combat methods.

Remember http://m.et for a second

The heart decapitation technique can be used with stealth in the soil, and the previous sneaking in the soil, Yichen's usage is very simple, all of which are to secretly close the distance with the enemy when the doppelganger attracts the enemy's attention, and then drill out of the soil, and then perform ninjutsu. It's embarrassing, and I feel like the role of stealth in the soil can't be played at all.

After all, if you want to get closer to the enemy, the best way is to use the teleportation technique to quickly approach. The suddenness of the teleportation technique is much better than stealthing in the earth.

But with the Heart Decapitation Technique, it is different, and you can inflict fatal damage on the enemy in the soil.

The purpose of exchanging camouflage is very clear, that is, to increase the tactical method, after learning this ninja, Yichen can use other means to stealthily approach the enemy in addition to sneaking in the earth. Moreover, the camouflage technique can make Yichen perform body skills and knife skills in a stealth state, which is very remarkable.

The last hardening technique,It's Yichen used to increase its own defense.,So far, Yichen's defensive ninjutsu,There's only one Earthflow Wall.,But the defense effect of the Earthflow Wall is too single.,And the ninja world's understanding of this ninjutsu is too thorough.,It's easy to be targeted.。 Yichen himself had used the high penetration of the water pressure line against this ninjutsu.

As for the two ninjutsu sent by Nagato, the technique of rock breaking is very suitable for Yichen, and Yichen will flow on the wall, which can be used to cooperate with the technique of rock crushing, and this technique is very unpopular, so it is a good method to use it for sneak attacks. The usefulness of the blister technique is somewhat narrow, and the frontal assault ability of the blister technique is not strong, and the power is not great. However, there is an advantage that it can be achieved in the center of flowering, and if you can punch the blister technique into the enemy's formation, you can attack from the inside out.

In terms of rich Yichen combat methods, these two ninjutsu are good.

It's just that the proficiency of these five ninjutsu newly learned is far from the level of actual combat. And the embarrassing thing is that Yichen doesn't have much time to spend on practicing ninjutsu.

In the past few days, Yichen will consume the chakra because of the cultivation of ninjutsu, and the rest of the time can be used to comprehend the changes in the nature of the fire attribute. Coupled with the help of the scroll given by Onogi, Yichen's fire attribute perception is not slow, and the progress is not small. So far, Yichen has been able to use the newly extracted chakra to ignite the dry wood.

The next step is to practice Fire Escape, and there are only two Fire Escapes that Yichen can choose, one is the Hao Fireball Technique obtained from the Konoha Outpost, and the other is sent by Nagato. Nagato sent two, one of which was also a fireball, and the other was a fire whip technique. Yichen's choice is naturally the technique of Hao Fireball.

It's just that now there are too few fire attributes released from maintaining balance in Yichen's body, so it's still very reluctant to use the Hao Fireball technique, how can I say that it can, it can be regarded as reaching the standard of the young man with soil. That is, you can spew a little flame out of your mouth.

Just this small flame can only be done by Yichen after consuming the water attribute chakra, and using the re-extracted chakra. If you use the chakra at the beginning, because the proportion of fire attributes is too low, Yichen can't even use a spark.

In addition, Yichen also used chakra test strips to test his fourth attribute, which is thunder.

This result is not disappointing, after all, Lei Dun is still very eye-catching in the original book, but unfortunately, the rock ninja village is not good at Lei Dun, and the inheritance of Lei Dun is the least of the five elements of ninjutsu.

But if it's Wind Escape, although Iwa Ninja Village is not good at Wind Escape, at least there are people around you who can learn from it. And the Thunder Ninja, Yichen doesn't seem to know any of them.

After Yichen recovered for a while, he stopped practicing ninjutsu, which is not something that can be achieved in a short period of time, and requires long-term proficiency. I'm going to leave for the border tomorrow, and Yichen still has to make some preparations.

This time, Yichen is the captain of the team, and the others can be rotated, but Yichen himself estimates that he will not have the opportunity to return to the village in at least half a year, so Yichen must make sufficient preparations when he goes to the border this time.

The first is the procurement of materials, this Yichen is already very familiar, but the materials purchased this time are more than the materials for arranging the enchantment. Because Yichen himself is one of the best sealing masters in the village, when he went to the border this time, the village did not arrange other sealing masters to help Yichen arrange the enchantment.

Yichen's current level of sealing technique is A-level, because of the increase in chakra, Yichen has been able to perform A-level sealing techniques independently. In order to set up a safe supply depot at the border, Yichen took a lot of supplies from the enchantment class, and also asked for two A-pole sealing techniques from Suwona that he had not learned before.

The enchantment class has a good impression of Yichen, and it can be said that Yichen has single-handedly contributed to the current status of the enchantment class in the village. Therefore, Suwon basically agreed to Yichen's request.

Coming out of the enchantment class, Yichen was a little eager to try, and with these materials, Yichen believed that his supply depot would definitely be able to be established soon.

Then Yichen almost spent all the savings from the recent mission, and all of them were used to buy daily necessities, although it was said that the village would provide the daily consumption of the supply station, but Yichen was still not at ease. Then he went to the logistics office to get the supplies needed for the supply station, and Yichen only learned that there was such a department in the village that was independent of the contribution department. And in terms of scale, I'm afraid it's even bigger than the contribution.

The staff of the logistics department first checked Yichen's identity, and then gave Yichen a list of materials that Yichen could receive. Then Yichen followed the staff to collect the items on the list one by one.

This is the first time Yichen has seen so many military supplies, and it turns out that the village is so rich. Seeing that the boxes where the kunai was placed were piled up like a small mountain, Yichen subconsciously wanted to convert it with silver taels or contribution points. But the thought was interrupted in time, it was too scary. You can't save so much in your lifetime by working on your own.

The materials that Yichen received were less than a drop in the bucket compared to the storage in the warehouse, but even so, the number of these materials was far beyond Yichen's imagination, so many materials were not suitable for the space scrolls to be loaded, and the space scrolls also cost money, even if Yichen was a master in this area, he didn't have so much time to make space scrolls specifically for these materials.

Because most of the space scrolls are disposable, even if some are of particularly good quality, they cannot be used indefinitely, and there is an upper limit on the number of times they can be used. It's not cost-effective to use it for these supplies.

Yichen couldn't carry so many materials, but for the staff of the logistics department, they did a lot of this kind of work, only to see dozens of shinobi come over, under the leadership of a middle ninja, load these materials, and then pull a car by one, and leave the village from the special passage, and finally put down the vehicle in a place outside the village.

Yichen followed them to this meeting point, and at a glance he judged that this was not a temporary meeting point, but should be a permanent transit point in the village. Because this place is very well guarded, just the patrol team, Yichen saw three squads. Yichen guessed that every time the supplies were transported to the front line, they were first counted and placed here, and then the designated ninja was responsible for escorting them.

Yichen's supply station has 44 people going to the front line this time, so there is no problem in terms of safety, and the staff of the logistics department told Yichen that tomorrow they will arrange a team to be responsible for transportation, but the security work will be handed over to Yichen himself. Yichen nodded in understanding.

Early the next morning, Yichen arrived at the gate of the village, and at this time, there were already several teams of ninjas waiting at the gate. Among them, Yichen saw his three subordinates and Mu Fuki. And Shinohara, they shouldn't have arrived yet.

When the three subordinates saw Yichen coming, they just nodded and said hello, they knew that it was not them who Yichen had to deal with today.

Yichen first stepped forward and said hello to Mu Fu, and then the two chatted for a while about their post-graduation experience, of course, they were just talking about it, ninja is not good, the confidentiality regulations are there, and you can't say much about the mission in public.

Although Yichen and Mu Chui are classmates, they are not particularly close, and although the relationship is good, they are still much worse than their teammates in the same group after being classified. So after Taniya and Fujino led the team to arrive, Yichen couldn't interject, and could only watch the three of them start to fight for a long time.
