At this time, Yichen's advantages as a traverser are reflected, the magic of chakra is endless, and it is not troublesome to solve the problem of fixing the form of water, it depends on what your chakra attribute is.

Thinking of this, Yichen couldn't bear it anymore, and immediately went out, went to the contribution exchange office next to the village task hall, and exchanged the contribution value obtained from copying the book for a chakra test paper.

After exchanging the test strip, on the way home, Yichen was a little distressed, and a test strip directly asked for Yichen's fifty contribution points. Eighty percent of the contribution value in exchange for copying books was directly spent.

The production of chakra test strips is not troublesome, and the high price is because it is just needed, and every ninja will buy one, otherwise the direction of the future road cannot be determined.

When he got home, Yichen couldn't wait to enter the chakra into the test strip, and then saw that the test strip was half wet and half crushed.

"Well, water and earth." Yichen muttered to himself.

The result is neither happy nor disappointed. The long-term goal of dust escape also needs fire and wind, and there is no fire and wind in Yichen's natural attributes, so if you want to develop dust escape, the difficulty is twice as high. And the problem of the front eye needs the soil attribute, so there is a chance to achieve it.

"Alas!" Yichen sighed, and cheered up again to ponder how to use the earth attribute to fix the form of water.

It's a very difficult project, but it doesn't go beyond the level of Yichen. Although Yichen's comprehensive strength is far less than that of ordinary ninja, his cultivation progress in ninjutsu can indeed be carried out in the next part. That's a change in nature.

When ordinary people can skillfully perform the three-body technique, the amount of chakra is almost enough to perform C-level ninjutsu. As long as you perform tasks for a period of time, adapt to actual combat with chakra, and become a ninja mentally, you can learn ninjutsu with attributes.

Then I will learn the nature change while learning the ninjutsu casting, and this time it is much more difficult than practicing the three-body technique. Considering the mission, chakra can't be used to perform ninjutsu to the fullest, so progress will be very slow. Except for some geniuses, they generally have to be specially trained by the village after becoming a middle ninja before they have the opportunity to learn a C-level ninjutsu.

Yichen's situation is special, although he is proficient in the three-body technique, but this all relies on super chakra control, and the amount of chakra is far from reaching the time when he casts C-level ninjutsu. It stands to reason that he doesn't need to practice the nature change now, because even if he does, it's useless. But now that Yichen had discovered a new use for the nature change, he simply decided to include the chakra nature change in his next cultivation focus.

The cultivation of the nature change, Yichen has no clue, and the cultivation of Naruto's wind attribute change in his memory is completely brainless, and it is all based on muscle memory. This method was not suitable for Yichen, and Yichen's physical condition determined that he was not suitable for this brainless cultivation method.

But it doesn't matter, in Iwa Ninja Village, there is no good way to practice anything else, but to practice the soil attribute, Ishikawa Sensei said, this is not a problem.

When he heard that Yichen was going to practice the change in the nature of the soil attribute, Mr. Ishikawa just frowned, and directly told Yichen that there was a special place in the village to practice the change of the soil attribute, and it was free and open, and anyone in the village could go there.

At lunchtime, Yichen followed the guidance of Teacher Ishikawa and came to the No. 9 training ground, which was different from other venues, where there were no targets for practicing kunai and no various humanoid puppets for exercising physical skills. There are only a variety of rocks of different shapes.

According to Ishikawa-sensei, these rocks are all kinds of earth escape ninjutsu performed by various upper ninjas since the founding of the land country. At that time, the first generation of Tsuchikage, the reason why he chose to build Iwa Ninja Village here was because he took a fancy to this land. Because this land can slow down the passage of the Tufu Chakra to a great extent.

Don't think it's strange, there are so many strange places in the ninja world that the perennial strong winds in the country of the wind can't be explained by common sense, and the thunder of the country of thunder can overturn the scientific theorem.

The advantage of Iwa Ninja Village is that it is a sacred place for cultivation in the earth.

Yichen followed the method taught by Ishikawa-sensei, wandering through this stone forest, looking for rocks that could resonate with his chakra. As long as you find this kind of rock and sit on the side and understand it carefully, there is a high chance that you will be able to cultivate the change in the nature of the earth's attributes. This advantage is the main reason why Iwa Ninja Village can have the largest number of ninjas among the five major countries, and it is because the cost of cultivating earth attributes is lower than that of other countries, so the land country dares to cultivate so many ninjas.

Yichen walked in it, this feeling is very wonderful, as if these stones have life and their own preferences, Yichen can clearly feel that some rocks are not close to him, some rocks are indifferent to him, and some are very yearning for himself.

These rocks that yearn for oneself are like children calling for their mothers, calling for Yichen to come closer. Yichen was not in a hurry, he first walked around this huge rocky area before finding a rock that he felt the most strongly.

The shape of this stone is a very regular spherical shape. According to the description in memory, this seems to be the one of the four people who cast a ninjutsu that can trap people inside and absorb chakra outside. What's it called, it seems to be a dungeon?

Yichen circled the ball several times, and finally chose a direction, which had the greatest sense of calling. Yichen then put his left hand on the ball, and his right hand stamped with one hand, and began to cast chakras into the sphere.

When Yichen's chakra came into contact with the original chakra in the sphere, Yichen seemed to have a connection with the master who performed this ninjutsu. In this kind of connection, Yichen saw some vague fragments, these fragments are some special experiences of the original owner, before this life, these pictures must have been impressive, but unfortunately the order is chaotic and difficult to sort out.

In addition, all of Yichen's minds are on understanding the feeling of the other party performing ninjutsu. So the content of these fragments is basically not remembered.

At this time, Yichen, who seemed motionless from the outside, seemed to be wrapped in a warm liquid, Yichen seemed to have returned to his mother's body, the whole person curled up, unable to move, I don't know how long it took, Yichen began to adapt to this feeling, and slowly stretched his limbs. Finally, Yichen stood in the mass of liquid and began to walk in small increments.

Yichen did not dare to step out of the liquid, but deliberately walked around all corners of the liquid. Experiencing this special feeling, I can't say what life experience there is, I can compare it with the current situation, it is as if something suddenly has something in my mind, and it seems that nothing has changed.

If you have to make an analogy, it's like learning to ride a bicycle in a previous life, before you learned it, you couldn't master your balance anyway, but after learning it, it was not easy to lose your balance.

Slowly, Yichen knew that the mass of things wrapped around him was Chakra, the earth-attribute Chakra, and it was the Chakra that the original owner left here. It's amazing that Yichen also knows how to transform the attributes of Chakra.

Naturally, Yichen opened his eyes and came out of his original motionless state. Only this time he wasn't outside the ball, but inside. It turned out that in the process just now, Yichen gradually integrated into the interior of the earth dungeon.

After Yichen came to his senses, he sensed the chakra in his body, and smiled bitterly, the chakra in his body had been exhausted. Although he didn't know why he was in this ninjutsu, Yichen knew that if he wanted to go out, he had to practice chakra first.

But another Yichen was speechless, and the chakra he had practiced was being absorbed by this ninjutsu little by little. This absorption rate is very slow, after all, I don't know how long this ninjutsu has been here. But Yichen himself doesn't have much chakra, and now he doesn't know how many chakras he needs to leave. If it wasn't enough, Yichen would have to be trapped inside and wait for rescue.

Fortunately, I just ate lunch, and I still have some chakra in my body that can be extracted. Yichen carefully sensed it, found a place with the slowest absorption speed, sat down, and meditated on refining the chakra. Now Yichen can practice standing up, and he can even practice while using chakra, but this will slow down the speed, and the chakra is not enough, if it takes too much time, it will only be absorbed more.

I don't know how long it took, Yichen felt that his body was almost at its limit, and then, according to the strange feeling he felt before, he released Chakra from his body, maintained it on the surface of his body, and then slowly pierced out of the dungeon.

After coming out, Yichen breathed a sigh of relief, and in just about a minute, the chakra in his body was almost consumed again. I glanced back, and the feeling of fear in my heart came up again. If you run out of chakras halfway through, you'll have to get stuck in it. Fortunately, there is no danger.

Yichen can come out of it in a way similar to the ninjutsu that sneaks in the soil, but it doesn't mean that Yichen can perform this ninjutsu now. It's that this dungeon has a special connection between chakra and Yichen. It can bring great convenience to his movements, which can support Yichen to get out of it. In another place, it is impossible for Yichen to use this method at all.

Although it was thrilling, but after all, it didn't cause any harm, Yichen was still happy and scared, this trip was not in vain, and he learned the changes in Chakra's soil attributes without knowing it.

Yichen walked towards the ninja school with excitement. It took a lot of time to practice chakra just now, and it took a lot of time to find a suitable chakra rock before, and now the ninja school is almost over. However, Yichen needs to report his safety to Mr. Ishikawa, and by the way, tell the other party the good news.

Seeing Yichen come back, Mr. Ishikawa was also relieved, he was also very worried, and he was already thinking that if Yichen didn't come back after school, he would go to the No. 9 training ground to look for Yichen.

Seeing that Yichen was obviously much more tired than at noon, Ishikawa-sensei comforted, "How is it?" Have you ever seen the magic of that place? You have fewer chakras, so your perception will be slower than ordinary people, and you can gain something by going a few more times than others. ”

Seeing that Mr. Ishikawa still wanted to comfort himself, Yichen hurriedly said, "Mr. Ishikawa, it's not like this. I've realized that I've succeeded. He described his previous experience in detail.

Teacher Ishikawa was speechless after hearing it, just Yichen's chakra, not even the percentage when he went to understand it back then. How many times did you go back and forth? Forget it, don't dare to calculate it.

Although Mr. Ishikawa was also a little afraid of Yichen's recklessness, but thinking of this rock forest, Yichen would go like this once, so he didn't talk to Yichen too much, so that Yichen avoided a bombardment of Shizhizhi's will.
