The so-called 'pure life energy' refers to the internal force of nature.

When Mu Feng transferred the internal force to Orochimaru and let him feel it for himself, Orochimaru finally showed some interest and made an evaluation.

"This energy is different from Chakra, it seems to be more pure, but it lacks the 'god' in the 'Spirit and Qi God', and it can only be used to perform physical arts, not illusions and ninjutsu."

"The teacher is right, but this energy also has its own characteristics, and it has a certain ability to recover. I feel that my body is much stronger than the average ninja! Mu Feng said confidently.

These words are actually hinting at Orochimaru: My tolerance is very strong, even if you use me as an experiment, don't be polite about the intercolumnar cells, I can bear it......

Orochimaru obviously thought of this as well, and after pondering for a long time, he said lightly: "You are indeed a little special, I am willing to accept you as a disciple, but after returning from the front line, you have to cooperate with me to do some experiments, I am very interested in the energy you have extracted."

In addition, I may not have much time to teach you ninjutsu, so first give you a ninjutsu scroll for you to practice by yourself, and if you don't understand something, you can ask Red Bean for advice. ”

As he spoke, he pulled out a ninjutsu scroll.

At the same time, a prompt sounded in Mu Feng's mind: "To trigger and complete the apprenticeship task, do you want to learn the 'Chakra Refining Technique'?" 500 points and 1 bronze medal required for study. ”

"Chakra Refining: After mastering, chakra can be extracted from the body, and the initial chakra level is related to the full attributes of the reincarnation. The higher the All stats, the higher the initial Chakra level. ”

Mu Feng did not hesitate and chose to study directly. This is a very crucial skill for the reincarnation to integrate into the Hokage world, and without chakra as a foundation, even if you learn the ninjutsu of this world, you can't use it.

Correspondingly, the threshold for this skill is also very low, and the reincarnation that enters the Naruto world can basically be triggered, and the points and medals required for certification are also very few.

However, with this skill alone, the speed of cultivating chakra is relatively slow......

"The learning was successful, and the initial chakra refining was in progress...... Congratulations on obtaining the special skill [Nakashinobi Beginner Chakra]. ”

As the prompt fell, Mu Feng's skill bar underwent some changes, and there was an additional [Middle Ninja Junior Chakra] behind the [Level 4 Internal Force]. It's just that the properties haven't changed in any way.

If you rely on your own cultivation to make Chakra advanced, it can improve your attributes.

'The middle ninja is primary, and it's almost the same as the intelligence. ’

For this result, Mu Feng was somewhat disappointed in his heart.

Fortunately, now that he has become a disciple of Orochimaru, there will definitely be opportunities in the future. Of course, there are also dangers......

"Thank you, teacher."

Seeing that Orochimaru handed him a ninjutsu scroll, Mu Feng immediately took it after saying thank you.

I got a ninjutsu so easily, if I let other reincarnators know, I am afraid that I will die of envy.

When I opened the ninjutsu scroll, the reminder sounded again: "Obtain ninjutsu [Shulker Snake Hand], E-level purple quality, 1200 points and 2 bronze medals required for certification." ”

'E-grade purple quality, is it so bad?' The smile on Mu Feng's face froze.

In fact, this is not bad, for the average silver reincarnation, the E-level purple skill is already very rare. It's just that he, who has a lot of D-gold skills, naturally doesn't look down on him.

"Not satisfied with this ninjutsu?" Orochimaru glanced at him, seemingly displeased.

Mu Feng hurriedly shook his head, "No, I'm very satisfied, but I don't know why, I always feel that this ninjutsu is very simple, and it seems that it can be learned at once." Teacher, is there anything more complicated, such as the Shulker Multi-Snake Hand......"

Orochimaru said coldly: "Don't be too ambitious, after learning the Shulker Snake Hand, I will teach you the Shulker Snake Hand." You go down and get ready, and I'll be waiting for you at the entrance of the village in two hours. Those elders were in a hurry, and it was time to go to the front line to support. ”

"Yes, Teacher." Mu Feng didn't dare to say anything more, and immediately quit the laboratory.

Walking on the street, Mu Feng touched the ninjutsu scroll in his arms, a little helpless, it seems that this skill will be learned if he doesn't learn it.

The reason why he is reluctant to learn this ninjutsu is because it has little effect and cannot increase his combat effectiveness; The second is because I don't want to spend these 1,200 points.

Don't look at 1,200 points is not much, but it costs a little here, some there, and it adds up to a lot.

You know, so far, he has spent 4,500 points in this reincarnation! Four thousand points are the entrance fee, and five hundred points are the cost of learning chakra refining.

Fortunately, before entering this world, all the equipment that was eliminated last time was sold, and a total of more than 16,000 points and three gold medals were obtained.

After removing the cost of this time, there are more than 17,000 points and five gold medals left. Say too much, say less and say less.

"Let's learn it."

Mu Feng no longer hesitated, and directly certified the [Shulker Snake Hand], and then chose to learn.

Speaking of which, this is the first ninjutsu he has mastered in his life.

He actually wanted to directly learn the more advanced [Shulker Multi-Snake Hand], but unfortunately, he needed to prove his learning ability before Orochimaru could teach himself other ninjutsu.

[Shulker Multi-Snake Hand] is a B-level ninjutsu, and if nothing else, it should be a D-level purple skill.

To be honest, this kind of ninjutsu is still not very attractive to Mu Feng, and only A-level ninjutsu and S-level ninjutsu can really make his strength improve by leaps and bounds.

However, it is too early to think about this.

Following the marks left by An Xiaocao and the others, Mu Feng soon joined them.

"You rented this house?"

After seeing the three of them in a house, Mu Feng couldn't help but ask.

"No, it's our three own homes, and the character identity comes with it. Cart...... Brother Hinata, Orochimaru didn't do anything to you, we are all worried about you. An Xiaocao said.

"I'm fine, Orochimaru is already my teacher, and it's safe for the time being. I'm going to go with him to support the front line right away, so be careful yourself. ”

"You'd better be careful with yourself." Xiao Lucky said lightly, "The three of us are going to take on some D-class missions in the village, which is much safer than you." ”

Mu Feng pondered for a while and said, "If it's possible, you'd better go to the ninja school and have a look, it should be able to trigger the [Chakra Refining Technique], which will be of great benefit to your integration into this world." ”

As he spoke, he also shared the information about the Chakra Refining Technique with them.

"Got it." Little Lucky replied and continued: "Be careful yourself. ”

"Be careful, too." Mu Feng said seriously, "If the village sends you to the battlefield, try to come to me." ”

"Hmm."
