The so-called "pure life energy" refers to natural internal energy.

When Mu Feng transferred his internal force to Orochimaru for him to experience it personally, Orochimaru finally showed some interest and made an evaluation.

"This energy is different from chakra, and it seems to be more pure, but there is less 'god' in the 'Essence Spirit', which can only be used to perform physical arts, but cannot be used to perform illusions and ninjutsu."

"The teacher is right, but this energy also has its own characteristics and has a certain recovery ability. I feel that my body's ability to withstand is much stronger than that of ordinary ninjas!" Mu Feng said confidently.

These words are actually hinting to Orochimaru: I have a strong ability to withstand it. Even if I do experiments, don’t be polite about Hashirama cells, I can withstand it…

Orochimaru obviously thought of this, pondered for a long time, and 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 extracted.

In addition, I may not have much time to teach you ninjutsu. I will give you a ninjutsu scroll first and practice it yourself. If you don’t understand anything, you can ask Hongdou for advice.”

As he said that, he took out a ninjutsu scroll.

At the same time, a prompt sounded in Mu Feng's mind: "Trigger and complete the apprenticeship task. Do you want to learn the 'Chakra Refining Technique'? 500 points and 1 bronze medal are required to learn."

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

Mu Feng did not hesitate and chose to learn directly. This is a very critical skill to allow the reincarnation to integrate into the Naruto world. Without chakra as the foundation, even if he learns the ninjutsu in this world, he will not be able to use it.

Correspondingly, the threshold for this skill is also very low. Reincarnations who enter the Naruto world can basically trigger it, and there are few points and medals required for certification.

However, with this skill alone, the speed of practicing chakra is slower...

"Successfully studied, initial chakra is being refined... Congratulations on obtaining the special skill [Zhongnin Junior Chakra]."

As the prompt sound fell, Mu Feng's skill bar changed some changes, and there was an additional [Zhongnin Jungin Jungle Primary Chakra] behind [Level 4 Internal Force]. However, the attributes did not change at all.

If you can advance chakra with your own cultivation, you can improve your attributes.

‘The Junin Nin level is similar to the intelligence.’

Mu Feng was somewhat disappointed with this result.

Fortunately, now that I have become an disciple of Orochimaru, opportunities will definitely be indispensable in the future. Of course, danger will also be indispensable in the future...

"Thank you, teacher."

Seeing Orochimaru handing him a ninjutsu scroll, Mu Feng immediately took it over after thanking him.

I got a ninjutsu so easily. If other reincarnation people know about it, I am afraid I will be envious of death.

When I opened the ninjutsu scroll, I saw the reminder sound again: "Get the ninjutsu [Surprise Snake Hand], E-level purple quality, 1200 points required for certification, 2 bronze medals."

‘Is E-level purple quality so bad?’ Mu Feng’s smile froze.

In fact, this is not bad anymore. For ordinary silver reincarnation practitioners, the E-level purple skill is already very rare. However, he, who has many D-gold skills, naturally doesn't like it.

"Don't be satisfied with this ninjutsu?" Orochimaru glanced at him, seemingly a little unhappy.

Mu Feng shook his head quickly, "No, I'm very satisfied, but I don't know why, I always feel that this ninjutsu is very simple, and it seems that I can learn it in one go. Teacher, is there any more complicated things, such as the Hidden Shadow Duo Snake Hand..."

Orochimaru said coldly: "Don't be too ambitious. After learning the Hidden Snake Hand, I will teach you Hidden Snake Hand again. You go down and prepare first. I will wait for you at the entrance of the village in two hours. Those elders are urging you very quickly. It's time to go to the front line to support you."

"Yes, teacher." Mu Feng didn't dare to say anything else and immediately withdrew from the laboratory.

Walking on the street, Mu Feng touched the ninjutsu scroll in his arms, feeling helpless. It seemed that he would learn this skill even if he didn't learn it.

The reason why he was reluctant to learn this ninjutsu was because it had little effect and could not increase his combat effectiveness; the other was because he did not want to spend these 1,200 points.

Although it is not much to get 1,200 points, it consumes a little bit here and there, and it adds up to a lot.

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

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

After removing the expenses during this period, there are still more than 17,000 points and five golden medals left. It is not too much to say more, and it is not too much to say less.

"Learn."

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

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

He actually wanted to directly learn the more advanced [Kan Yingda Snake Hand], but unfortunately, he needed to prove his learning ability first so that Orochimaru could teach his other ninjutsu.

[Secret Shadow Snake Hand] is a B-level ninjutsu. If nothing unexpected happens, it should be a D-level purple skill.

To be honest, such ninjutsu is still not very attractive to Mu Feng. Only A-level ninjutsu and S-level ninjutsu can truly make his strength improve by leaps and bounds.

However, it is too early to think about these things now.

Following the marks left by An Xiaocao and others, Mu Feng quickly met with them.

"Did you rent this house?"

After seeing three people in a house, Mu Feng couldn't help asking.

"No, it's our three of us, and the character identities are included. Car... Brother Hyuga, 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 soon. Be careful."

"You'd better be careful about yourself." Xiao Xingyun said lightly, "The three of us are going to take on some D-level tasks in the village, which is much safer than you."

Mu Feng pondered for a while and said, "If possible, you'd better go to the ninja school to see it. It should be able to trigger [Chakra Refining], which will be of great benefit to you integrating into this world."

As he said that, he also shared the information about chakra refining with them.

"I understand." Xiao Xunyun responded and continued, "Be careful."

"You must be careful too." Mu Feng said seriously, "If the village enlists you to the battlefield, try to come to me."

"Um."
